Alumina Ceramics:
99 alumina ceramics vigorously develops the production of raw material styrene, and completely solves the problem of lack of polystyrene raw materials. The lack of raw materials restricts the development of polystyrene production, so solving the problem of raw materials is one of the keys to the development of polystyrene production. According to forecasts, the domestic production capacity of polystyrene will reach 2.2 million tons by 2005 and 3 million tons in 2010. The demand for styrene is very large, and the planned styrene production capacity still cannot meet the demand. The huge demand of polystyrene for styrene provides the two major oil and petrochemical group companies with a good opportunity to develop styrene production. The two major group companies are important domestic styrene producers. Trying to expand the production capacity of styrene can help domestic The production of polystyrene provides sufficient raw materials, and can seize the opportunity to occupy the market and obtain better economic benefits. 2. Seize the opportunity to actively occupy the domestic market. In recent years, the country has severely cracked down on smuggling and regulated imports. In order to reduce costs, some domestic users who used imported raw materials have begun to look for domestic suppliers that can replace imported products. This has brought excellent performance to domestic polystyrene manufacturers. opportunity. Domestic polystyrene production enterprises should seize the opportunity, strive to improve product performance and quality, and strive to replace imported products in the largest range. In short, as long as appropriate measures are taken, domestic polystyrene production can be well developed. It is not advisable to adopt an attitude of giving up easily.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
