The production line of XPS foam board was introduced in China

Extrusion foam insulation board is a kind of insulation material, which mainly used for building insulation, cold storage, highways, railway subgrade and other fields, and xps raw material is polystyrene resin. In 2013, China's total output of extruded foam reached 19 million ㎡, in the building insulation materials market share has more than 70%. It is reported that Tianjin Tianxi Sunshine introduced the Austrian Basset environmental extruded polystyrene foam board production line, which marks the world's most advanced environmentally friendly extruded polystyrene project officially settled in Tianjin.

Tianjin Tiandi Sunshine Insulation Materials Co., Ltd. is specialized in building energy conservation and environmental protection insulation materials integrated enterprise. It has established nearly 20 years and adhere to the conscience of a quality enterprise development concept, adhere to product quality, arduous pioneering, concerned about the cause of environmental protection and energy conservation, production of products widely praised by the market, and thus become similar enterprises Leader. In 2011 through the Ministry of Environmental Protection and the United Nations Development Program and other relevant agencies to assess the official into the China Environmental Protection Association governing units, China Building Materials Association governing units. This indicates that the Tianjin world sunshine will face a greater opportunity for development, will also lead the entire Tianjin and North China-related insulation products to further upgrade, and then for China's environmental protection and energy conservation to make a more solid contribution.

China's extruded foam insulation board industry is currently the main use of hydrogen fluoride-containing blowing agent. This kind of blowing agent to disperse into the atmosphere will damage the ozone layer, but also a strong greenhouse gas, produce benzene, formaldehyde and other harmful substances, great harm to the human body. Therefore, the accelerated phase-out of hydrochlorofluorocarbons is not only significant for the protection of the ozone layer, but also greatly slows global warming.

Some actions we can take to prevent the “white pollution”

1, unified thinking and understanding, strengthen management. In accordance with the "publicity and education as the guide, to strengthen the management as the core, recycling as the main means to replace the product as a supplementary measure" as the principle of prevent and control the white pollution, one is to strengthen the "white pollution" harmful propaganda, guide and educate the public conscious (Such as railways, water transport, civil aviation, tourism, restaurants, restaurants, retail, etc.). Through the strengthening of management, changing the unmanned, disorderly stacked, free to the "white pollution". The second is a large number of waste plastic packaging industry. The third is to take coercive measures, from the collection of waste plastic packaging (such as disposable bubble lunch box) to start, and gradually improve the recycling of waste plastic packaging. Fourth, to strengthen the alternative packaging product development, research, take efforts to reduce the amount of waste plastic packaging production.

2, enact the relevant laws and regulations to control the "white pollution". Let the producers, sellers and consumers know the importance of the plastic recycling, such as EPS recycling, and other waste plastic package recycling. obligations and legal responsibility. We should formulate specific control measures and guidance policies to control the production of waste plastic packaging materials that are not easy to be recycled and encourage the improvement of the recycling rate of waste plastic packaging materials in response to the production, operation and consumption of plastic packaging materials.

3, the development of appropriate economic policies, based on the market economy to eliminate the "white pollution" of the benign operation mechanism. The use of economic means to encourage and promote waste plastic packaging "reduction, resource, harmless", conservation and comprehensive utilization of resources, prevention and control of "white pollution" to protect the ecological environment.

Chinese salt polluted by micro-plastic is a rumor

Recently, a report on the discovery of micro-plastics in China's commonly used salt, widely reported and reproduced by domestic and foreign media, which has aroused public discussion and concerns about salt safety. In this regard, the experts who carry out the marine environment in the micro-plastic research, Li Tao said that the relevant facts must be clarified to solve the social concerns about edible salt.

"Marine plastic pollution is a global environmental problem." Professor Li Daoji said that research shows that the world's 192 coastal countries entered the plastic waste in the ocean about 400 to 12.7 million tons in 2010, the ocean almost became a "plastic world". So plastic recycling such as EPS recycling is very necessary to protect our environment. And then we can reuse it to do some other products.

Professor Li Daoji said that the pollution problem of marine plastic waste has aroused great concern from all over the world, especially coastal countries. Since 2007, China has also started the routine monitoring of marine waste including plastic waste. The number of samples in the acquisition accounted for more than 90%, micro-plastics generally present in the estuary and coastal waters. The researchers in the laboratory also studied the pollution of micro-plastics in sea salt, the main concern is the marine micro-plastics into the human food network approach. Our salt is just an example in this study.

Professor Lee said, acquire the micro-plastic from the salt may be minimal. Due to the complexity of the exposure pathways and the difficulty of detection. It is not possible to estimate how much plastic an ordinary person will consume in daily life every day. As a result, the public does not need to worry too much about the micro-plastic salt. Salt containing micro-plastic is just an example of the impact of our products on micro-plastics, and also a warning to each of us.

The future development trend of EPS industry

The fifth meeting of the 12th CPPCC National Committee was held on March 3 and closed on March 13. The fifth meeting of the 12th National People's Congress was held on the morning of March 5 and closed on the morning of the 15th. After the end of the two sessions, the related policies of all walks of life have been released, then which policies will affect the EPS industry?

Vigorously develop the assembly of buildings

The delegates of the two sessions proposed to increase the proportion of assembly buildings, the so-called assembly of buildings, refers to the prefabricated components assembled at the site of the building. The advantages of this building is the fast speed of construction, limited restrictions by climate conditions, and can also save labor force and can improve the quality of the building. For the decoration of the external decoration works mainly refers to the insulation construction, and EPS insulation board is widely used in cast-in-place wall insulation, so this policy will promote the the consumption of EPS .

Transforming Shantytowns

On the one hand, transform shantytowns can enhance the amount of external wall EPS insulation board; on the other hand, the policy indirectly stimulating the home appliances consumption, thus stimulating the demand for foam packaging. From this point of view, in the next few years, it will increase EPS consumption.

Speed up the development of new materials technology

Graphene as one of the new materials, in recent years, has become very popular. For the EPS industry, graphite EPS has developed rapidly of the current domestic production enterprises, which have a number of mass production. And graphite EPS insulation sheet has a better insulation properties, flame retardant properties and mechanical properties, which is more in line with energy saving and environmental protection standards.

Overall, the assembly of buildings, transform shantytowns and graphite EPS are all have policy support in the future time which will pull the EPS industry consumption, and accelerate the transformation of traditional industry to graphite EPS industry .

Although the large usage of EPS, the EPS can easily become the white pollution, so EPS recycling is very necessary to protect our environment. And then we can reuse it to do some other products, which can form a benign cycle.

Plastic pollution threatens marine ecological environment

According to the United Nations website reported that on June 23, 2016, the first United Nations Environment Conference opened in Nairobi, capital of Kenya. The United Nations Environment Program (UNEP) released the 2014 Yearbook, which reviewed the ten most pressing environmental issues over the past 10 years. The yearbook points out that a large amount of plastic waste in the ocean is increasingly threatening the survival of marine life and the development of tourism, fisheries and commerce. According to a conservative estimate, plastic waste annually caused economic losses of up to 13 billion US dollars.

At a press conference held on the afternoon of June 23, officials from the United Nations Environment Program (UNEP) said that the 2014 Yearbook had re-examined and assessed the top ten pressing environmental issues and raised their response. The research areas of the yearbook include plastic waste in the ocean, environmental effects caused by excessive nitrogen, air pollution, wildlife poaching, marine aquaculture and other fields.

The United Nations Environment Program has issued a yearbook for 10 consecutive years since 2003, focusing on global development and environmental issues. The 2014 Yearbook is the conclusion of the past 10-year changes, which is also a prediction of the future global environmental situation.

The "Assessment of Plastic Value Report", jointly funded by the United Nations Environment Program and the "Plastic Disclosure" project and the "real cost" program, pointed out that the plastic consumption of the consumer goods industry consumes as much as $ 75 billion a year in natural costs. In these natural costs of consumption, more than 30% of the capital consumption is used for the extraction and treatment of plastic raw materials caused by greenhouse gas emissions, marine pollution control in which is an important proportion. So plastic recycling such as polystyrene recycling is very necessary to protect our environment. And then we can reuse it to do some other products.

Express garbage recycling surviving resistance

With the rapid development of e-commerce, online consumption has become the main force to stimulate consumption, online shopping and other new consumption patterns effectively drive the development of the national economy. However, behind its continued prosperity, it faces a huge environmental burden. The issue of express trash has also been a number of representatives of the concern.

                                         

Usually the packaging industry used in the packaging materials are divided into tranches, envelopes, cartons, plastic bags, woven bags, tape and buffer. Due to the lack of specialized recycling management, most express packaging after a one-time use will be discarded into garbage. Among them, the delivery of plastic bags may also be a lot of residual plasticizers, flame retardants and other toxic and hazardous substances, not only cause waste of resources, pollution of the water and soil environment can not be overlooked.

Reporters learned that, for the courier company, the recycling of second-hand carton profits are less, usually do not spend human and material resources to recover. It is reported that due to different sizes and materials, express carton prices from 0.1 yuan to more than ten yuan, and most of these cartons 0.5 yuan per kilogram to 0.8 yuan price to the scrap collection station. A courier company courier said that now the pace of work quickly, they will not waste time in the recycling session, such as polystyrene recycling.

                                    

The express delivery packaging specifications should be standardized, the development of standards for express packaging materials, in principle, the use of recyclable, biodegradable materials. The use of non-degradable materials to be strictly limited, and gradually prohibit the use of non-recyclable, non-degradable materials. Li Jianhua representative told reporters that the current state of the express delivery industry, electricity business packaging standards, guidance has not expressly provided earlier this year, the State Post Bureau issued the "express development" thirteen five "plan" to standard this industry.

How to identify different types of plastic？

The basic method of distinguishing different types of plastic and its composition is through some commonly used analysis and detection instruments, such as infrared spectrophotometer, chromatograph, x-ray diffractometer, colorimetric instrument, nuclear magnetic resonance instrument and so on. However, the general plastic packaging printing plant does not have such equipment, so if a more simple method can quickly determine an unknown plastic, which in the actual work is more valuable. The easiest initial identification method is combustion method and tear identification method.

(1) combustion method: thermosetting plastic in the heat will be brittle, hair coke, but not soft; and when a certain temperature to reach a certain temperature soft, or even melting, which is the system to identify the basic boundaries of these two types of plastic.

Chlorine, phosphorus. Fluorine and silicon plastic are not easy to fire or self-extinguishing, on the contrary, sulfur and nitro-based plastic is easy to fire and burning. Ethylene, propylene, isobutylene and other plastic and alkane compounds similar structure, combustion characteristics are similar. Compounds with benzene rings and unsaturated double bonds (such as diene polymers or copolymers) are black smoke when burned.

When the plastic heat will break down and produce special smell. For example: polymethyl methacrylate, polystyrene, polyoxymethylene can be heat decomposition into monomer; polyethylene, polypropylene is cracked into carbon atoms ranging from carbon; polyvinyl chloride, polyvinylidene chloride decomposition of hydrogen chloride The All of these heating and burning phenomena, can be used for classification and identification of plastic basis.

(2) plastic composite film tear identification method: the blade will be cut with 1cm composite film openings, and then hand tear. Such as easy to tear, is a cellulose film. If it is not easy to tear is a polypropylene film. If it is difficult to tear is a polyethylene film, directional Yixiang film or polyester film.

    Although the large usage of polystyrene, the polystyrene are disposable, which can easily become the white pollution, so polystyrene recycling is very necessary to protect our environment. And then we can reuse it to do some other products.

Replace the ordinary plastic bag with starch bag

In the real life, people are always afraid to come into contact with toxic plastic. But if we tell you that the plastic bag can be used by starch, are you be afraid? The National People's Congress, Jiangnan University Vice President, State Key Laboratory of Food Science and Technology Jin Zhengyu put the promotion of the use of starch bags recommended to the venue.

A survey shows that China's annual oil production and imports of about a quarter of the production of plastic products, of which about 30% produced to make food packaging, disposable tableware, shopping bags, etc., and about 40% of the products will become "white pollution", which caused the enormous pressure on the environment. So plastic recycling polystyrene recycling is very necessary to protect our environment. And then we can reuse it to do some other products.

 Jin Zhengyu told reporters that many countries in the world have introduced varying degrees of plastic restrictions to encourage bio-based materials in the field of food packaging applications. If China's food packaging bags can be replaced with biological-based materials, not only can effectively control the "white pollution", but also to the safety of the human body.

Compared to cheap plastic bags, many people worry that bio-packaging bags are too expensive to use. For this worry, Jin Zhengyu smiled and told reporters: "With starch manufacturing bags in the technology has been relatively mature, and now the national corn stocks are high, corn starch prices are very cheap.We measured, according to traditional plastic 20% starch-based materials Alternative, theoretically every year there will be more than 20 million tons of market demand.To blown film end products starch content of 30%, plastic, injection molding end products starch content of 50% or more, is expected to consume 800-1200 million starch per year Ton, the conversion of corn 1150-1700 million tons of cost and the current plastic bag is almost the same.

Plastic Particles have a Bad Effect to Human Beings

Researchers have found plastic particles in many lakes around the world, and the Lakes Institute sees plastic particle search as one of the regular works. Researchers use advanced techniques to reflect the structure of the lake, but it is difficult for them to rely on this technology to discover plastic particles on the lake because of the large lake area. Lake always has different depth and strong mobility. A series of objective conditions for the search of plastic particles caused many difficulties.

The lake is beautiful and the scenery is very spectacular. But with the social and economic development, people produce and use too much plastic products. Waste plastic products such as waste plastic bags and foamed food trays lead to severe environmental pollution. In fact, the researchers not only found polystyrene particles in the lake, but also found that many other objects, such as hard plastic parts, plastic film and even fishing people left the fishing line. In addition, there are plastic beads used in daily necessities and beauty products. The data were at the same level as the Mediterranean, and the researchers also found plastic particles in the fish.

Through all these signs, people began to worry about the size of plastic particles from inland freshwater lakes and rivers that spread to the world's oceans. Researchers say they are studying the hydrophobic contaminants on these surfaces that may be eaten and are absorbed by birds and fish.

Plastic plays an important role in changing many aspects of people's lives. Specifically, the plastic can do anything, so it leads to its presence in any place. More and more problems are exposed to us, plastic decomposition may last for a century. However, we can recycle these plastic to make the pellets, such as ps pellets, which can make other products like the frame.

Plastic Heat Resistance Index and Classification

Compared with the metal, ceramics, glass and other traditional materials, the shortcomings of plastic is that heat resistance is not high, which often limits its use in high temperature occasions.

In plastic materials, different kinds of plastic heat resistance is different; some heat is very low, and some are higher. Heat-resistant plastic generally refers to the heat distortion temperature of 200 ℃ above a class of plastic products.

The ways to measure heat resistance of plastic products are good or bad is according to heat distortion temperature, Martin heat temperature and Vicat softening point, of which the most commonly used is heat distortion temperature.

According to the plastic heat resistance of the size, the plastic will be divided into the following four categories:

① low heat-resistant plastic, which the hot deformation temperature is less than 100 ℃ of a class of resin. Specific varieties are: PE, PS, PVC, PET, PBT, ABS and PMMA. However, some of the plastic products are disposable, which can easily become the white pollution, so plastic recycling such as polystyrene recycling is very necessary to protect our environment.

②the hot deformation temperature of heat-resistant plastic is 100 ~ 200 ℃ between a class of resin. Specific varieties are: PP, PVF, PVDC, PSF, PPO and PC, and so on.

③the hot deformation temperature of high heat-resistant plastic between 200 ~ 300 ℃. The thermal deformation temperature of polyphenylene sulfide (PPS) is up to 240 ℃, the thermal deformation temperature of chlorinated polyether can reach 2l0 ℃, the heat distortion temperature of polyarylsulfone (PAR) can reach 280 ℃, PEEK Hot deformation temperature of up to 230 ℃, POB thermal deformation temperature of up to 260 ~ 300C, Fused PI heat distortion temperature of 270 ~ 280 ℃, amino plastic heat distortion temperature of 240 ℃, EP heat distortion temperature of up to 230 ℃, PF heat distortion temperature up to 200 ℃.

④the ultra-high heat-resistant plastic which hot deformation temperature greater than 300 ℃ of a class of resin. The heat distortion temperature of polyphenylene imidazole

(PBI) can reach 435 ℃, and the heat distortion temperature of non-fusion PI can reach 360 ℃.

Emerging Marine Pollution

The ocean is the largest recipient of water on earth, and millions of tons of plastic waste are dumped into the ocean every year. The latest data from the United Nations Environment Program (UNEP) showed that plastic production has increased by 20 times since 1964 and 322 million tonnes in 2015, equivalent to 900 Empire State Buildings. At least 8 million tons of plastic per year will flow into the ocean, the equivalent of every minute there is a plastic filled with garbage truck into the ocean. According to the current consumption rate of development, by 2050 the earth will add 33 billion tons of plastic. Plastic accumulation in the ocean, the current world of marine floating plastic waste is estimated to be as high as 2.7 billion, 250,000 tons, the ocean has become almost a "plastic world."

It is estimated that by 2050, the total weight of the plastic in the ocean may exceed the sum of the fish, 60% -90% of the marine waste is plastic. For you and me, a plastic bag, a plastic bottle is insignificant, but for marine life it may be fatal "weapon" - turtles, whales and seabirds and other biological intake will be sick or even destroy the ecosystem of coral reefs, resulting in chemical pollution.

Some plastic waste is easy to break down, some is difficult to break down. In the decomposition process, the plastic will release toxic substances, such as phthalates, bisphenol A and so on. At the same time, scientists are increasingly aware that the plastic head changes may also be "toxic", large plastic dismemberment of plastic fragments, small plastic decomposition into tiny plastic, micro-plastic and then split into micro-plastic. Gradually, marine micro-plastic pollution as a new of the marine pollution problem, has gradually become a new hot topic of global scholars.

So plastic recycling such as polystyrene recycling is very necessary to protect our environment and marine. And then we can reuse it to do some other products.

How renewable plastic break out of tight encirclement？

In recent years, the negative impact of rapid economic growth has become increasingly prominent, environmental problems have to face the reality. With the steady development of the domestic economy, the government has increased the maintenance and management of the environment, recycled plastic industry is directly dizzying, the operation can be imagined.

First look at the domestic recycling industry's largest production base - Laizhou market. According to the experts in the recycling industry, he said that the recycling of plastic such as polystyrene recycling is the most important thing in their town, they will severely crack down the illegal production in the enterprises. To solve the problems like the market supply shortage, the little quantity of import materials, the customs strict investigation and is difficult into it, renewable materials prices continue to rise.

                                 

Recycled plastics how to break out of the industry is the focus of attention, the current production of enterprises are generally through the EIA certification and in the provisions of the park production enterprises. According to Jin Lianchuang research, the current recycling industry, 3/4 of the enterprises without a license or illegal production, in the cleaning of sewage at random discharge or treatment but can not meet the national standard.

Recycled plastics industry is an indispensable raw materials in recent years, the annual domestic supply is about 20 million tons, the imports quantity is more than 700 million tons. Environmental protection is imperative, the industry must make a choice.

                               

The enterprises should use purify equipment, and strive to meet environmental standards, to obtain environmental certification. And then part of the enterprises which do not meet the standards should move to the park to ensure that the environment will not be polluted. Part of the miniature and workshop manufacturers will be closed. Cracking down the non-cleaning waste plastics, part of the product through the surrounding environmental lax Vietnam, Thailand and other countries, should be cleaned and then customs.
