1. Introduction
Aluminum Chlorohydrate(ACH) its molecular formula is Al2 (OH) 5Cl · 2H2O. It is an inorganic polymer compound with a degree of alkalinity (basicity) higher than that of polyaluminum chloride and second only to aluminum hydroxide.
It is a white solid powder, and its solution is a colorless transparent liquid. ACH liquid is characterized by the highest aluminum content of 23% Al2O3 (w / w) in any solution-based aluminum product on the market, the 83% -90% basicity of ACH is also the highest in any solution-based aluminum salt.
It has strong bridging adsorption performance, is easily soluble in water, and is accompanied by physical and chemical processes such as electrochemical, coagulation, adsorption and precipitation in the hydrolysis process.
The highly polymerized aluminum in ACH has a higher cationic charge than standard salts such as alum or polyaluminum chloride or even other aluminum salt products. Therefore, ACH can provide higher levels of performance and reduce overall usage. The high acid-neutralizing ability (alkalinity) also means that when using ACH, the effect of pH on the water environment is negligible. Compared with traditional metal salts and polyaluminium chlorides with low salinity, ACH can also effectively condense in a wider range of pH (such as 5-9.5).
2. Uses
Usedas ingredient for pharmaceuticals and the special cosmetic(such asantiperspirant)in daily chemical industry, drinking water purification, industrial wastewater treatment, paper industry and so on.
