Basic Aluminum Chloride

Basic Aluminum Chloride is an inorganic polymeric high-valent polyelectrolyte flocculant, which can be considered as an intermediate hydrolysis product between aluminum chloride and aluminum hydroxide. Its chemical formula has various representations, such as [Al2(OH)nCl6-n] or Al(OH)2Cl, Al(OH)Cl2, etc., depending on its preparation method and process conditions. Basic Aluminum Chloride is usually a black or white powdered substance with high solubility and chemical stability.

Physical and Chemical Properties:

• Appearance: Black or white powder.

• Solubility: Easily soluble in water, forming a colloidal solution.

• Acidity and Alkalinity: Weakly acidic substance with a pH value typically ranging from 4.0 to 5.0. When dissolved in water, it releases hydroxide ions, causing the water to exhibit an alkaline reaction.

• Density: The density varies depending on the preparation method and process conditions but is generally high.

• Melting Point: The specific melting point varies depending on the chemical formula and purity but is usually high.

Application Fields:

• Water Treatment: As a flocculant, it is used to purify domestic water, industrial water, mine water, oilfield reinjection water, etc., effectively removing suspended solids, organics, heavy metals, and other impurities from the water.

• Papermaking: Used for sizing in papermaking to improve the quality and strength of paper.

• Textile Printing and Dyeing: As an auxiliary agent in textile printing and dyeing, it enhances printing and dyeing effects and product quality.

• Other Industries: It is also widely used in precision casting hardening agents, refractory binders, glycerol refining, sugar syrup refining, fabric crease resistance, pharmaceuticals, cosmetics, and other industries.

  
  

Usage Instructions:

1. Depending on the condition of the raw water, a small-scale test can be conducted beforehand to determine the optimal dosage.

2. When using, mix and dissolve Basic Aluminum Chloride solid with a certain proportion of clear water (e.g., 1:9 to 1:15). Note that solutions with aluminum oxide content below 1% are prone to hydrolysis, reducing their effectiveness; high concentrations are difficult to dose uniformly.

3. Add the flocculant according to the optimal dosage determined by the small-scale test and adjust as needed during operation.

   
   

Precautions:

• Basic Aluminum Chloride solutions should be prepared and used immediately and should not be stored for too long, usually not exceeding 24 hours.

• It is strictly prohibited to mix, transport, or store it with toxic substances. When storing, attention should be paid to waterproofing, moisture prevention, and preventing package damage.

• Water treatment chemicals from different manufacturers or brands cannot be mixed or stored with other chemicals.

• During use, avoid prolonged and excessive mechanical stirring to prevent it from affecting its effectiveness.

• When using solid Basic Aluminum Chloride, first dissolve it in water to a certain concentration, then dilute it to the desired concentration with additional water; during dissolution, add water first, gradually feed the material, and stir continuously.

• Wear protective equipment during operation to avoid direct skin contact or inhalation of its dust.
