Control of polyaluminum chloride degree of alkalinity on the relationship between the degree of base and the coagulation effect than the control degree of alkalinity of polyaluminum chloride on the relationship between the degree of base and coagulation than the effect of solid or liquid polyaluminum chloride in Under the same dosage, the coagulation effect of Chinese products is better than that of foreign products. In general, according to the same production process, the higher the basicity of the polyaluminum chloride product is, the lower the unit consumption and the cost of the raw material are; and in the case of the same dosage in the water treatment, the alkalinity in the consumed water is less. With appropriate process technology, liquid polyaluminum chloride can reach a stable period of more than 1 year, not less than the traditional craft products. Liquid products in different drying process, the basic degree of salt increased by 2% to 4%. When the basicity of the salt is raised to more than 85%, accurate calculation and process control of the feedstock are required, and the difficulty of solid-liquid separation also increases. Therefore, advanced technology is required. Polyaluminum chloride basicity and coagulation effect relationship: 1, the basicity of the aluminum is one of the most important quality indicators of aluminum chloride products, but also the most important production control parameters. 2, OH, Al equivalent than the basicity and coagulation effect and production control conditions have a good correlation, therefore, the concept of basicity of the salt is still of practical value. 3, liquid polyaluminum chloride base index, taking into account the feasibility of production control, production costs and coagulation effect, the proposed standard value of 45% to 90%. 4, solid polyaluminum chloride base index, based on the value of the liquid base, taking into account the increase of the degree of drying of the base, the proposed standard value of 45% to 95%. 5, improve the basicity of polyaluminum chloride products, can greatly improve the economic benefits of production and use. Salt base from 65% to 92%, the cost of raw materials can be reduced by 20%, the use of cost can be reduced by 40%. Polyaluminum chloride product of the degree of alkalinity generally need to control the 50-80% of this range. Since polyaluminum chloride is composed of a mixture containing different base numbers, the degree of alkalization measured on the product during production is an average value, so that the degree of alkalinity control of basic aluminum chloride in the actual production process Should not be too high, the degree of alkalization in the production process should be controlled at about 65% is appropriate, this time the product flocculation performance is better. Reasonable control of polyaluminum chloride degree of polyaluminum chloride product use effect is very important, more about polyaluminum chloride application technology, you can focus on the purification of the official website: http://www.gyzhenyu .com /
