Polyaluminium Chloride

Polyaluminium Chloride (Polyaluminium Chloride) abbreviation PAC. Usually also known as alkaline aluminum chloride or coagulant, etc., it is between ALCL3 and AL (OH) 3, a water-soluble inorganic polymer, chemical test [AL2 (OH) NCL6-NLm] which m on behalf of the degree of polymerization, n represents the degree of neutrality of PAC products. The color is yellow or light yellow, dark brown, dark gray resin-like solid. The product has strong bridging and absorbing properties, and in the process of hydrolysis, it is accompanied by the occurrence of physicochemical processes such as coagulation, adsorption and precipitation.

It is mainly used as flocculant in the treatment of domestic water, production water and industrial sewage (such as oil-containing sewage, printing and dyeing, paper sewage, steel mill sewage, etc.), as well as the treatment of high toxicity heavy metals and fluorine-containing sewage, etc.; In addition, it also has a wide range of uses in precision casting, tanning, and so on.

Characteristics: This product is suitable for all kinds of high and middle turbidity source water treatment, especially for high turbidity water purification has a particularly obvious effect, it alumina formation fast, large, easy to settle, suitable for a wide range of source water PH, corrosive small, low labor intensity of workers.

Polymerization of aluminum chloride dilution method of use:

    In order to achieve the effect of flocculant and economic benefits, the user can be based on different source water turbidity, different seasons and different reaction conditions, through experiments to determine the amount of dosage per thousand tons of water. The product is prepared into 3%-5% aqueous solution (calculated according to the weight of the product).

1. Dissolve the solid product into liquid by adding water at 1:3, then add 10-30 times of water to dilute it into the required concentration and use it.  

2, the dosage can be determined according to the different turbidity of the raw water, the general turbidity of the raw water in the 100-500mg / L, per thousand tons of dosage of 10-20kg.

Packing and storage:

1, lined with plastic bags, the outer layer of plastic film woven bag packaging, the weight of each bag is 25kg.

2、Store in a cool and dry place, protected from sunshine and rain.
