Materials commonly used in plastic washbasins

The raw material of ordinary plastic basin is general plastic, which generally refers to plastic with large output, wide use, good formability and low price. There are five kinds of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene (ABS), all of which are thermoplastics.

1 Advantages of plastic pots: Most plastic pots have strong corrosion resistance, do not react with acid and alkali, are low in manufacturing cost, durable, waterproof and light, and are good insulators, beautiful and convenient.

2. Disadvantages of plastic pots: Burning plastic will produce toxic gases, such as toluene when burning polystyrene. Inhalation of a small amount of this substance will lead to blindness, vomiting and other symptoms, and PVC combustion will also produce toxic gas of hydrogen chloride.

Extended data

key property

Most plastics are light in weight, chemically stable and will not rust; Good impact resistance; Good transparency and wear resistance;

Good insulation and low thermal conductivity; Generally, it has good formability and coloring, and the processing cost is low; Most plastics have poor heat resistance, high thermal expansion rate and easy combustion; Poor dimensional stability and easy deformation; Most plastics have poor low temperature resistance, become brittle at low temperature and are easy to age; Some plastics are soluble in solvents.

Plastics can be divided into thermosetting and thermoplastic, the former can not be used in plastic, and the latter can be produced repeatedly. The physical elongation of thermoplastics is relatively large, generally 50%~500%. Under different elongation, the force does not change completely linearly.

The different properties of plastics determine their industrial use. With the development of technology, the research on plastic modification has never stopped. It is hoped that in the near future, this modified plastic can be widely used, even replacing steel and other materials without polluting the environment.
