We know that the production process there are many kinds of PAC, the article we introduced some of its manufacturing process, today we come to you in the following types of PAC's interpretation of what the production process. First, boil fumed crystalline aluminum chloride at a temperature pyrolysis coke plant PAC, to break down the hydrogen chloride and water, and then polymerized into a powdery clinker, after adding a certain amount of water and stir, short curable resin products, after drying to obtain PAC solid product. Second, adding alkali to configure certain concentration of aluminum chloride solution, at a certain temperature was slowly added dropwise with vigorous stirring while a certain amount of aluminum hydroxide solution, the reaction until the solution became clear, the supernatant liquid product is PAC . Al mass fraction is generally considered a micropipette alkali (alkali very slow speed) the product obtained up to 80%, by raising the temperature by means of total aluminum concentration was prepared 0.59 mol / L PAC production, Al's the mass fraction of up to 80.7% of the product. But abroad has been reported at low concentrations of aluminum, the base can not be added slowly but in the 90 c = Al by rapid addition of base available under Al mass fraction of 100% of the PAC solution, by dropping legal base PAC was prepared product allegedly Al content is not high. Advantages of introducing and analyzing the performance of PAC 1, PAC iron nutrients needed by the body is beneficial to human health. 2, the use of ferric chloride PAC can effectively remove the source of the water after the aluminum ions and aluminum coagulation water residual free aluminum ions form. 3, PAC PAC waterworks fast hydrolysis, hydration weak, dense form of alum PAC, settlement rate, by the temperature change is small, meet the water produced during flow cut shear requirement. Especially in dealing with high temperature and high turbidity water, low temperature, low turbidity water, it has a unique effect. 4, PAC precipitate netting mechanism when the metal salts (such as aluminum sulfate or ferric chloride) or metal oxides and hydroxides (such as lime) as when coagulant, when adding large enough to prompt precipitation of metal hydroxides (such as Al (OH) 3, Fe (OH) 3, Mg (OH) 2 or a metal carbonate (such as CaCO3), the particles in the water may be the formation of these precipitates in the netting when The precipitate is positively charged (Al (OH) 3 and Fe (OH) 3 in the neutral and acidic pH range), the settling velocity can be due to the presence of anions in solution is accelerated, for example, silver sulfate ion. Further water particles themselves These metal oxides can be used as the core of the formation of oxide precipitates, so condensation is removed inversely proportional to the concentration of substances in the best dosage of agent, that is, the more particles, the less metal cohesion agent dosage.
