Aluminum
hydroxide chloride ach is an inorganic polymer with higher alkalinity
(basicity) than PCA, second only to aluminum hydroxide. It is bridged and
polymerized by hydroxyl groups, with the highest hydroxyl groups in the
molecule. It is a white powder solid, and the solution is a colorless
transparent liquid. The content of alumina in the liquid product is more than
23%, and the content of alumina in the solid product is 46%~50%. It has strong
bridging and adsorption properties and is easily soluble in water. The
hydrolysis process is accompanied by electrochemical, coagulation, adsorption,
and precipitation physical and chemical processes.
Aluminum
hydroxide chloride ach is a highly polymerized solution of polymerized aluminum
chloride. It is characterized by a maximum aluminum content of 23% Al2O3 (w/w)
in any solution-based aluminum products on the market. It has the highest ACH
content of all aluminum salt solutions, ranging from 83% to 90% of the
salinity. The degree of salinity (alkalinity) refers to the degree of acid
neutralization and represents the degree to which the polymerized aluminum in
ACH is highly polymerized.
Highly polymerized aluminum in ACH has a higher cationic charge than standard salts such as alum or polymerized aluminum chloride, or even other aluminum salt products. As a result, ACH can provide a higher level of performance and lower overall power consumption. The high level of acid neutralization (alkalinity) also means that the effect of water pH is negligible in ACH applications. Compared to conventional metal salts and low alkalinity alumina polymers, ACH effectively coagulates over a wider pH range (e.g., 5-9.5)
.
Treatment
of municipal drinking water.
ACH is a
flocculant for standard water quality treatment of purified water, drinking
water, and domestic water. The product comprises pure aluminum and edible
hydrochloric acid, which is synthesized through a multi-course process. The
product's quality conforms to the USP-34 standard of the U.S. Pharmacopeia and
the standard of the European Union and the European Community. It greatly
exceeds China's drinking water treatment GB15892-2009 standard and has become
an internationally recognized drinking water treatment agent.

Daily-use
ACH is commonly used as an ingredient in antiperspirants (e.g., antiperspirant
lotions, drops) and is the main raw material for the production of AZG
(Aluminum Zirconium Glycinate Hydrate).
Additive
for graphite products.
Adding
hydroxy aluminum chloride liquid to graphite products increases the aluminum
content and enhances the fire resistance and other graphite products' physical
and chemical properties.
