Alumina Ceramics:

The discarded polystyrene of alumina ceramics cannot enter the biogeochemical cycle through biological decomposition and photolysis. Due to the low specific gravity of expanded polystyrene (styrofoam), it floats on the water or drifts with the wind, causing subjective landscape damage. According to the California Coastal Commission (California Coastal Commission) investigation, polystyrene has been the main marine drift. Ingestion of such plastic marine organisms can cause damage to their digestive system. The demand is strong, the consumption growth rate is amazing, and the market potential is great. Since the 1990s, China's polystyrene demand has been strong, and consumption has grown rapidly. In 1999, the national total consumption of polystyrene reached 2.43 million tons, an increase of more than 10 times over 1990, and the average annual growth rate reached 27.6%. The growth rate was second only to ABS resin among the five general synthetic resins, which was the world average growth rate during the same period. More than 6 times the speed. It is predicted that the demand for polystyrene in China will continue to grow steadily in the future, reaching 3.17 million to 3.3 million tons in 2005 and 3.9 million to 4.2 million tons in 2010. The market prospects are quite optimistic. Insufficient production capacity, high import dependence and strong domestic demand. Although China's polystyrene production capacity has grown rapidly, it is still far from meeting demand and has to rely on large amounts of imports. In 1999, China's polystyrene production capacity was about 1.4 million tons, of which the production capacity of high-impact polystyrene/general-purpose polystyrene was about 1 million tons, and the production capacity of expandable polystyrene was estimated to be more than 400,000 tons. . At the same time, the total output of polystyrene in the country in 1999 was about 940,000 tons, which was far from the demand. In order to meet demand, China imported 1.517 million tons of polystyrene resin in 1999, an increase of nearly 10 times over 1990, and the dependence on imports exceeded 60%.
