what is aluminum chloride hydroxide

2020-12-01

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.

 

The recognized advantages of replacing high polyaluminum solutions are.

-Improved turbidity removal capacity and increased flocculation rate.

Improved TOC (Total Organic Carbon) removal.

-Reduced filtration turbidity, shortened filtration stroke, and increased throughput.

--Improved removal of iron, fluoride, cadmium, radioactive contamination, and oil slicks.

-Reduce the number of reagents used, simplify the process, and eliminate the effects of pH and secondary electrolytes added.

--Reduce the overall production cost of tap water.

Municipal and Industrial Water Treatment.

Applications of ACH in specialty wastewater treatment.

-Add color removal function

-Removes -TSS (Total Suspended Solids).

-Removal of heavy metals such as chromium, cadmium, lead, mercury, etc.

-Removal of phosphorus, fluoride, oil slicks, etc.

-More than 50% sediment reduction (50% sludge reduction)

--Eliminates the effects of pH and the addition of secondary electrolytes, reducing wastewater treatment costs.

--Reduction of COD (chemical oxygen demand) in industrial wastewater treatment.

-Biochemical Oxygen Demand (BOD) and Total Organic Carbon (TOC) removal in municipal wastewater treatment.

Pulp and Paper Manufacturing Applications

Sizing and precipitating agents, cross-linking agents

-Dimensional adhesives

-Anionic trash remover.

-Retention aid filter aids.

-Resin barrier control additive.

ACH Applications in Other Industries

-Precision molding as a coagulant and flame retardant.

--Decolorization of printing and dyeing wastewater.

Pharmaceutical, rubber, tanning, petroleum, and chemical industries.

-Aluminum zirconium crosslinkers, aluminum zirconium coupling agents, etc.

Cosmetic raw materials and resin manufacturing.

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.
