The polystyrene are disposable, which can easily become the white pollution, so Styrofoam recycling is very necessary to protect our environment. And then reuse it to do some other products.
Polystyrene foam agent is made of polystyrene resin, adding foaming agent and other additives, it is a cushioning material that used frequently. China's polystyrene foam production mainly concentrated in the northeast, Jiangsu and Zhejiang and Beijing, Tianjin, Hebei, and which is small and medium enterprises.
When the density of polystyrene foam sheet is insufficient, if it is used for exterior insulation of building exterior wall will lead to its low tensile strength, which easy to make the middle of the EPS board was broken; at the same time, the low EPS board density will lead to lower insulation performance and increase hygiene, which will affect the building insulation effect, polystyrene foam board will not achieve the role of building energy conservation insulation.
At present, China's EPS production enterprises is about 2000, polystyrene foam production momentum is good, and the quality continues to increase. But the number of large enterprises are less. It is reported that the apparent density refers to the volume per unit of the foam in the specified temperature and relative humidity conditions. The apparent density affects the other physical performance to a certain extent and directly reflects the cost of the product.
China's thermal insulation materials market started late, especially organic materials, thermal insulation materials market development is lagging behind. Over the past decade, the state actively promote the development of energy-efficient buildings, reduce energy consumption, making the expansion of polystyrene board thin plaster external wall insulation technology has been widely used.
And these materials can be recycled through Styrofoam recycling solutions, which not only can protect the environment, but also can save the waste resources.
