What are the areas in which aluminum foil is applied?
With the development of industry and the rapid growth of urban population, the pollution of water resources is becoming more and more serious. The sewage that needs to be purified is also increasing day by day, and the demand for water purifying agent is increasing. As a result of polyaluminium chloride molecules in the number of hydroxyl groups, when polyaluminum chloride added to hydrolysis in muddy source water, water under the condition of pH, accompanied by condensation, adsorption, sedimentation and a series of physical and chemical process, so as to achieve the purpose of water purification. The sources of waste aluminum foil are very extensive, mainly from cigarettes, food and pharmaceutical packaging, etc. the main component is aluminum, which has high economic value and social value of recycling. After experimental study, the best conditions of polyaluminium chloride from aluminum foil and the scope of application, has certain practical significance in improving the utilization rate of resources and protect the environment.
International and domestic production and application of inorganic polymer flocculant have scale, theoretical research has also been further developed. The main raw materials are bauxite, aluminium hydroxide, waste molecular sieve catalyst and so on. The main preparation methods are wet method, electrolysis method and so on. Some scholars believe that the aluminum foil has the advantages of high recovery and reuse of economic value. He experimentally studied the optimum conditions for the preparation of polyaluminium chloride by using waste aluminum foil and the applicable range of the purified water
Preparation of polyaluminium chloride from waste aluminium foilPolyaluminium chloride is a common inorganic polymer flocculant. The wide range of raw materials for the production of polymeric aluminum chloride sets the foundation for its development. Especially, the production process is various, which provides convenience for the development of polyaluminium chloride.
