| Plastic products are made of plastic as the main raw material of daily necessities, industrial products collectively. Includes injection molding of plastics raw materials, plastic, all technology products. Plastic articles for daily use has the following advantages: most plastic corrosion resistance ability, not with acid, alkali reaction; Plastics manufacturing costs low; Durable, waterproof, lightweight; Easy plastics made in different shapes; A good insulator; Plastics can be used in the preparation of fuel oils and fuel gas, this would reduce oil consumption. Plastics and other materials, are the following features: 1, light weight. Plastic is lighter material, relative density between 0.90-2.2. It is clear that can float on the surface of plastics? Especially foam plastic, porous texture, light, relative density is only 0.01. This makes plastic products that can be used to reduce weight. 2, good chemical stability. Most of the plastic to acid, alkali and other chemicals has a good resistance to corrosion. In particular commonly referred to as King of plastics PTFE (F4), it is better than gold, even the chemical stability, put in ' Aqua ' Cook for more than 10 hours from going bad. F4 has excellent chemical stability and corrosion resistance is an ideal material. F4 can be used as to transport corrosive and viscous liquids pipeline material. 3, excellent electrical insulation properties. Ordinary plastic is a poor conductor of electricity, the surface resistance, resistance is very large in size, with numbers up to 10,911,018 ohms. Breakdown voltage and dielectric loss angular tangent value is very small. Therefore, the plastic has been widely used in the electronics and machinery industries. Plastic insulated control cables. 4, poor conductors of heat, noise, vibration reducing function. In General, the low thermal conductivity of plastic, equivalent to 1/75-1/225 steel, foams in porous media with gas, heat insulation, noise, shock better. Such as polyvinyl chloride (PVC) thermal conductivity only 1/357 of the steel and aluminum 1/1250. In thermal insulation capacity, single glass-plastic pane 40% higher than the single glass with aluminium Windows, double glass and high 50%. The plastic form when it is combined with insulating glass in residential, Office, ward to hotel use, save on heating in winter, saving of air-conditioning in the summer, benefits are clear. 5, wide distribution and high strength mechanical strength. Some plastic as hard as stone, steel, some soft, such as paper, leather; Plastics hardness, tensile strength, elongation and impact strength, mechanical properties, wide distribution, there is a great deal of choice. Plastic small proportion, intensity, which has a higher specific strength. Compared with other materials, plastics also has obvious shortcomings, such as flammability, high stiffness than metal, ageing resistance difference, heat and so on. |
