Under normal circumstances. For the price of PAC, the three major indicators of polyaluminum chloride can greatly improve the economic benefits of production and use. The polyaluminum chloride content is 40-95% (base degree is adjustable). 3. Improve the base degree of polyaluminum chloride products, raw materials production costs can be reduced by 20%, the use of cost can be reduced by 40%. 2, aluminum content, the basic degree of salt. The basicity of the salt is increased from 40% to 90%: 1. For solid polyaluminum chloride, the index of basicity is important and the basicity of the salt is higher. Today, first of all, to introduce you to the PAC aluminum chloride base aluminum chloride national standard is 40-90 What is the basicity of PAC? The level of basicity for the product of the use of what effect, the higher the price, the less dosage. At present, the higher the basicity of the salt is the spray-dried polyaluminum chloride, water-insoluble, basicity index is an important indicator, but also a reference index produced by the manufacturer. Salt base degree is one of the most important quality indicators of polyaluminum chloride products
