1, basicity: PAC in some form of hydroxylation degree level or alkalized called basicity or alkalinity. Usually with hydroxyl aluminum molar ratio B = [OH] / [Al] percentage. Basicity is one of the most important indicators of PAC, has a very close relationship with the flocculation. Raw water concentration, the higher the salinity, the better flocculation. To sum up, in the raw water turbidity 86 ~ 10000mg / L range, optimum basicity PAC 40% to 85%, Spirit PAC, PAC and many other features are the salt degree related. 2, pH value: pH PAC solution is also an important indicator. It represents the number of solution OH- free state. PAC pH value generally increases with increasing basicity, but for a different composition of the liquid, there is no correspondence between the pH and basicity. Liquid has the same degree of concentration of salt, when the concentration is not the same, its pH value is also different. 3, the alumina content: PAC alumina content is a measure of the product's active ingredient, it has a certain relationship with the relative density of the solution, the greater the relative density in general, the higher the alumina content. PAC related to viscosity and alumina content, viscosity increases with increasing alumina content. Under the same conditions, the same concentration of alumina conditions, PAC viscosity lower than aluminum sulfate, is more conducive to transport and use. A variety of production processes Saatchi PAC 1, acid-step hydrochloric acid, adding water by a certain percentage in a certain amount of aluminum ash, at a certain temperature adequate response, and after several hours of aging. Supernatant liquid that is released PAC obtained liquid product. Aluminum is exothermic, if good control of reaction conditions such as the concentration of hydrochloric acid and the amount of water and feed rate and order, PAC manufacturers can take advantage of aluminum exothermic heat of reaction, the reaction to reduce the amount of heat of external dependence even without external heat source and the reaction by self-heating, Xi'an PAC, control its basicity to qualified. This method has a fast response, low investment, simple process, convenient operation, high product basicity and alumina content, which the law has been widely used in the country. However, this process is more serious corrosion of equipment to produce the product impurities, in particular heavy metal content easily exceeded, unstable product quality. Ruan Fuchang such as the use of aluminum powder, AR hydrochloric acid as raw material, prepared in the laboratory out of the ultrapure PAC, the PAC said to be useful laboratory prepared standard solution.
