Synthetic plastic to promote industrial development and the improvement of people’s living standards have made tremendous contributions. In the early development of the plastics industry, the chemical stability of synthetic materials is one of great concern and focus on content. A few years later, its stability has been solved. Dramatically, today it has become the stability of a further hinder the development of important reasons. “Agricultural film” is a good illustration. Since it is difficult to be biodegradable and can only be used once, the easiest approach is to be burned. This is not only a waste of resources, but will also cause air pollution.
Recycling and use of waste plastics, has become a worldwide issue. The traditional method of landfill and incineration are gradually being reused, replaced degradation or decomposition process. Recycling of waste plastics, can not only protect the environment, save energy, but also has a good economy.
Expanded polystyrene waste crushing, adding perlite and cement, mortar, mixing evenly, conservation 3 days on the roof, natural drying, then disappearing into the cement mortar with lightweight concrete insulation. With the low cost of production materials into the legal system, good insulation, the house cool.
Waste foamed polystyrene, and dried with cheap phenol or chlorine hydrocarbon residue dissolved by adding toughening agents and anti-wear agent to reconcile into a film impermeable glue-like, or by blowing the surface of coated glass cloth, can be dried into roofing or waterproofing membrane pipes. After cooling the solvent can be recycled.
