Electrical industry is the production of power generation, transmission and distribution, industrial electrical equipment and special electrical equipment and other products based industries. The state will include the industry in China's equipment manufacturing industry focused on the development of industry.
In this case,
Plastic insulation with its characteristics, is widely used with the electrical industry, the current plastic has become one of the leading electrical products. Its development trend is also rising all the way, the electrical industry, the number of plastic consumption of plastic total consumption of the third, second only to the packaging and construction industries.
In this case,
Electrical appliances in the common plastic mainly PP, ABS, PC, PS and so on. Here's a look at their role in the electrical appliances to play it.
In this case,
ABS is the electrical and electronic industry, the largest use of plastic varieties, mainly for manufacturing shell. ABS biggest advantage is easy processing, good stability, easy to color, the price is relatively low. China's large-scale white goods enterprises to the steady increase in the demand for ABS each year, accounting for about half of the total demand for ABS. In addition, ABS in the IT industry such as notebook computer cases and communications products such as mobile phone shell has a large number of use.
In this case,
PS polystyrene in the IT and electronic products on the application is also more widespread, especially the IT industry, computer chassis, and so most of the use of high-impact PS (HIPS). Some of the higher hardness and transparency of the product is also widely used in this material, such as washing machine products on the popular roof of the transparent design, this transparent cover is also a considerable part of the use of HIPS manufacturing.
In this case,
PC in engineering plastics is a very special category. Its application area is relatively simple, but the amount is quite big. According to statistics, China PC resin in about 20% for alloy modified materials, and nearly 70% for the production of CD products. In addition to PC / ABS alloy, PC-GF is also often used in electrical and electronic alloy materials. The material of ABS less some of the features, but has its own characteristics, can greatly improve the material's environmental corrosion resistance, for the production of less than 1mm thin-walled parts, the thermal performance better than ABS, heat More uniform dispersion; the biggest drawback is the texture of poor flexibility, more brittle and fragile. CD-ROM disc manufacturing is the largest use of PC, China is about 400-500 CD production line, in accordance with the average consumption of each production line 200 tons / year PC conservative calculation, the annual CD-ROM to be consumed PC8-10 million tons. At present, PC has more than nylon, as China's largest use of engineering plastics.
In this case,
PP is one of the most active plastic materials, especially modified PP, there is a tendency to replace low-end engineering plastics. At present, the application of PP in electrical and electronic applications is mainly the use of additives such as adding glass fiber modified products, this material has a high impact strength and temperature performance, mechanical strength has also been significantly improved, the appearance of ABS than some products More smooth, and can use its transparency to produce some transparent parts.
In this case,
China's plastics industry's rapid and sustained development, has formed a complete industrial system categories, and into the ranks of the world's plastics power. The development of the plastics industry strongly supported the rapid and sustainable development of the electrical industry.
