1. Good processing characteristics
Plastics can be processed into products of various shapes according to the requirements of use, and the processing technology is simple, which is suitable for mechanized mass production.
The density of plastic is between 0.8-2.2g/cm3, generally only 1/3-1/4 of steel, 1/2 of aluminum, and 1/3 of concrete, similar to wood. Used in decoration projects, it can reduce the construction intensity and reduce the weight of the building.
3. High specific strength
The specific strength of plastic is much higher than that of cement concrete, close to or even higher than that of steel. It is a kind of lightweight and high-strength material.
4. Small thermal conductivity
The thermal conductivity of plastic is very small, about 1/500-1/600 of metal. The thermal conductivity of foam plastic is only 0.02-0.046W/mK, which is about 1/1500 of metal, 1/40 of cement concrete, and 1/20 of ordinary clay bricks. It is an ideal thermal insulation material.
5. Good chemical stability
Plastics have better corrosion resistance to general acids, alkalis, salts and greases, which are much better than metal materials and some inorganic materials. Especially suitable for doors and windows, floors, walls, etc. of chemical plants.
6. Good electrical insulation
Generally, plastics are poor conductors of electricity, and their electrical insulation is comparable to ceramics and rubber.
7. Good performance design
It can be made into engineering materials with various special properties by changing the formula and processing technology. Such as high-strength carbon fiber composite materials, sound insulation and heat preservation composite panels, sealing materials, waterproof materials, etc.
8, rich in decoration
Plastic can be made into transparent products or products in various colors, and the color is beautiful and durable. It can also be made with advanced printing, embossing, electroplating and bronzing technology with various patterns, patterns and surface three-dimensional impressions. , Metallic products.
9. Conducive to the industrialization of construction
Many construction plastic products or accessories can be produced in the factory and then assembled on site, which can greatly improve the efficiency of construction.
