用高岭土及芒硝替代氢氧化铝和纯碱生产冰晶石的技术,由天津市科赋康技术发展公司开发成功,并获国家专利。这种新技术可以生产高分子比和低分子比的冰晶石,生产过程中没有三废排放。通过半工业性生产实践,证明其技术可靠。采用此专利技术生产冰晶石,经济效益、环境效益高。建一座年产3000t能力的厂需投资730万元,一年就可收回全部投资,其生产原料广泛易得,不仅能生产主产品,而且可利用生产中生成的石膏和高岭土渣开发水泥副产品。同时,冰晶石是铝冶炼厂不可缺少的助熔剂,随着铝工业的飞速发展,
The technology for producing cryolite from kaolin and mirabilite instead of aluminum hydroxide and soda ash was successfully developed by Tianjin Kefukang Technology Development Co., Ltd. and won the national patent. This new technology can produce cryolite with a high polymer ratio and a low molecular weight ratio, and there is no emission of three wastes during the production process. Through semi-industrial production practices, it is proven that its technology is reliable. Using this patented technology to produce cryolite, the economic benefits and environmental benefits are high. To build a plant capable of producing 3,000 tons per year, a total investment of 7.3 million yuan will be required. The entire investment can be recovered in a year. The raw materials for its production are widely available. Not only can the main products be produced, but also cement by-products can be developed using the gypsum and kaolin slag produced in the production. At the same time, cryolite is an indispensable flux for aluminum smelters. With the rapid development of the aluminum industry,
