[Chinalco.com] Chinalco Shandong Branch's chemical alumina plant is China National Aluminium Corporation's chemical alumina production base, and 4A zeolite is one of the main products of the company and is used in the detergent industry. At present, 4A zeolite is affected by the structural adjustment of the downstream detergent industry, and the growth rate has slowed down. The factory reviewed the situation, adjusted the product structure, and seized market opportunities to develop a special zeolite product for PVC materials. After market research, the plant found that the use of 4A zeolite as an additive for PVC stabilizing additives to replace the original lead salt, has the advantages of reducing environmental pollution, low cost, favored by the manufacturer, and the 4A zeolite produced by the chemical alumina plant With high whiteness and low heavy metal content, it is more suitable for the production of PVC stabilizers. They organized technical R&D personnel to invest in the research, development, and trial production of special zeolites for PVC materials, transform the equipment, purify the production process, try out the users, and promote the market. The products soon entered the market. At present, the 4A zeolite product used as a stabilizer for PVC materials has formed a large-scale production and has a stable market share.
