Product Description:
ACh is a kind of inorganic polymer compound with higher alkalinity (salinity) than polyaluminium chloride and lower than aluminum hydroxide This product is bridged and polymerized through hydroxyl groups, with a relatively high number of hydroxyl groups in the molecule. The solid is white powder, and the solution is colorless and transparent liquid.
Product features:
The aluminum content of this product is up to 23% Al2O3 (w / W). It is a product with relatively high aluminum content in all aluminum salt solutions. The basicity is 83% - 90%, which is also higher in any solution based aluminum salt. The basicity (Alkalinity) refers to the degree of acid neutralization and also indicates the degree of polymerization of polyaluminum in ACh. High polyaluminum in ACh has higher cationic charge than standard salts such as alum or polyaluminum chloride or even other aluminum salt products. Therefore, ACh can provide a higher level of performance and reduce the overall consumption. The high acid neutralization capacity (Alkalinity) also means that the impact of pH in the water environment can be ignored when ACh is applied. Compared with traditional metal salts and polyaluminium chloride with low basicity, ACh can also effectively agglomerate in a wider pH range (e.g. 5-9.5).
