Recycling of polystyrene foam has become a hot topic for relevant enterprises.
most of the waste polystyrene foam is disposable. Millions of tons of white garbage are discarded and placed in nature, which can neither rot and transform, nor disappear by itself. This on the one hand leads to serious environmental pollution, on the other hand, it is also a waste of precious non renewable resources, How to effectively recycle the waste polystyrene foam has attracted the attention of researchers all over the world
at present, the recycling method of waste polystyrene foam is to crush it, melt it, regenerate it, granulate it into another material particle, and then add the corresponding auxiliary agent to process it into another material. For the above-mentioned method of recycling, reusing, grinding and processing, which cannot be strictly aligned to zero, the common practice is to crush, melt, brace, cut and shape the plastic foam through the crusher first. However, in the production of this kind of plastic particles, there will be incomplete crushing of raw materials, uneven melting temperature control, and it is impossible to avoid impurities mixed in raw materials, resulting in extremely low production efficiency, At the same time, the existence of impurities will cause equipment damage
polystyrene plastic can only be used once at present, which has caused a great burden to the environment, so a new recycling method is imminent
waste polystyrene foam, but the aerospace surface of the friction wheel table in the gearbox shall not be oiled or splashed with oil. Plastic refers to the polymer synthesized by free radical polymerization of styrene monomer. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100 ℃, so it is often used to make all kinds of disposable containers that need to bear the temperature of boiling water, as well as disposable foam lunch boxes. Because of its good water resistance, heat insulation, insulation, low moisture absorption, strong seismic strength, light weight, firmness, easy to form, low price and other characteristics, it is widely used in the fields of packaging, moisturizing, waterproof, heat insulation, shock absorption, decoration, catering and other fields, and penetrates into all departments of the national economy
