Physical and chemical properties: inorganic polymer compound, white solid powder,

soluble in water. The solution is a colorless and transparent liquid, with a 50% liquid specific gravity of 1.33-1.35g/ml (20℃). The aqueous solution is weakly corrosive, but it is still a general cargo by sea.

The brand name of Aluminum Chlorohydrate is ACH, which is an inorganic polymer compound with a degree of alkalinity (basicity) higher than that of polyaluminum chloride and second only to aluminum hydroxide. It bridges and polymerizes through hydroxyl groups, with the highest number of hydroxyl groups in the molecule. It uses aluminum ingots and hydrochloric acid to synthesize through multiple processes, and its product quality standards meet the USP-34 standard of the United States Pharmacopoeia and the European Union EC standard. Higher than my country's drinking water treatment GB15892-2009 standard. It is a white powdery solid, and its solution is a colorless and transparent liquid. The content of aluminum oxide in the liquid product is more than 23%, and the content of aluminum oxide in the solid product is 46% to 48%. It has strong bridging adsorption performance and is easily soluble in water. The hydrolysis process is accompanied by physical and chemical processes such as electrochemistry, condensation, adsorption and precipitation.

ACH is a highly polymerized solution of polyaluminum chloride. It is characterized by having the highest aluminum content of 23% Al2O3 (w/w) among any solution-based aluminum products on the market. The ACH of 83%-90% basicity is also the highest among any solution-based aluminum salts. The degree of basicity (basicity) refers to the degree of acid neutralization, and also represents the degree of polymerization of polyaluminum in ACH.

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 a higher level of performance and reduce the overall usage. The high acid neutralization capacity (alkalinity) also means that when ACH is applied, the impact of the pH of the water environment is negligible. Compared with traditional metal salts and polyaluminum chloride with low basicity, ACH can also effectively condense in a wider range of pH (such as 5-9.5).

Daily chemical grade aluminum chlorohydrate ACH is commonly used as an ingredient in antiperspirant and antiperspirant cosmetics. It is also the main raw material for the production of AZG (hydrated aluminum zirconium glycinate). Liquid aluminum chlorohydrate can be used as an additive to be added to graphite products to increase the aluminum content and enhance the fire resistance and other physical and chemical properties of the graphite products. As flocculant: used as municipal water treatment flocculant, drinking water purification treatment and in urban sewage and industrial wastewater (especially wastewater treatment in the automotive industry), in the papermaking industry (sizing precipitant, cross-linking agent), casting, printing, etc.

Packaging, storage and transportation:

Liquid cosmetic grade aluminum Chlorohydrate is packed in 200L PE drum (250kg/blue barrel or 275kg/blue barrel, up to 280kg/barrel) and water treatment grade liquid 1000L IBC drum (1350kg per IBC). Foreign trade export customers: IBC drum 24.3 tons/20'FCL  200l drum (250 kg/drum, 20 tons/20'FCL; 275 kg/drum, 22 tons/20'FCL)  liquid bag 25 tons /20'FCL; Domestic customers: One large truck of water treatment grade liquid: 31.05 tons (23 IBC drums).

Solid aluminum Chlorohydrate is 25kg outer paper bag plus PE inner film bag, foreign trade export customers: 25kg bag, 20 tons per 20'FCL. Domestic customers: One large truck of water treatment grade powder: 32 tons. Transportation is general transportation. Bulk liquids are weakly corrosive to metals, so non-metallic tanks or anti-corrosion containers must be used. Once spilled or a large amount of leakage occurs, it can be washed with water and will not cause harm to the environment. Solid products are afraid of moisture, please place them in a cool and ventilated place, and protect them from rain during transportation.
