Abstract
The present invention processes waste residue as raw material with aluminium section bar, open up a new raw material approach of producing polymerize aluminum chloride, adopted the operational path of and hydrochloric acid reaction direct with aluminium section bar processing waste residue, slough product colour by charcoal absorption and obtain water white liquid aluminium polychloride product, this products production cost is low, quality is high, reaches Japan and Drinking Water in China processing polymerize aluminum chloride quality standard.
Description
The present invention is a kind of novel process of synthesized polymer aluminum chloride.
The preparation of polymerize aluminum chloride, China mainly with the aluminium ash as raw materials for production, its production technique is simple, production cost is lower, but poor product quality.Japan mainly be with crystalline aluminium hydroxide as raw materials for production, its production technology requires high, cost is also high, but good product quality.Method with aluminium section bar processing waste residue synthesized polymer aluminum chloride at home and abroad still is not reported.
The objective of the invention is to process waste residue as raw material, open up a new raw material approach of producing polymerize aluminum chloride, and the novel process of the production polymerize aluminum chloride that a kind of production cost is low, quality product Gao Bingneng curbs environmental pollution is provided with aluminium section bar.
Aluminium section bar processing waste residue, from being crystalline aluminium hydroxide in essence, because of bringing various impurity into, its purity can not show a candle to the purity of industrial crystallization aluminium hydroxide, these impurity bring many difficulties for synthetic high-quality polymerize aluminum chloride, the reaction rule that synthesizes dimerization aluminium with aluminium section bar processing waste residue is with similar with crystalline aluminium hydroxide synthesized polymer aluminum chloride, promptly under the situation of high aluminium chlorine chemistry equivalence ratio, adopt high temperature and suitable reaction, improve the transformation efficiency of aluminium section bar processing waste residue as much as possible, improve the salinity of polymerize aluminum chloride, reduce the consumption of raw material hydrochloric acid, thereby reduce the cost of polymerize aluminum chloride product.With polymerize aluminum chloride synthesized polymer aluminum chloride, because of raw material is brought various impurity into, cause reaction product to be golden yellow, for synthetic high-quality polymerize aluminum chloride, the present invention has adopted activated carbon treatment technology, obtain colourless transparent liquid, through atom extinction spectrum analysis, the content of toxic heavy metal element is far below the polymerize aluminum chloride quality standard index of Japan and China's processing drinking water in the polymerize aluminum chloride, obtained satisfied result, proved that with aluminium section bar processing waste residue be that raw material can synthesize high-quality polymerize aluminum chloride product.
