Polyaluminum chloride, referred to as polyaluminum, abbreviated as PAC in English, is an inorganic polymer water treatment agent. Types are divided into two types: domestic drinking water and non-domestic drinking water, and different relevant standards are implemented respectively. Appearance form is divided into liquid and solid two. Due to the different ingredients contained in the raw materials, the appearance and color are different, and the application effect is also different.

Physical data
1. Properties: Colorless or yellow solid. Its solution is colorless or yellow-brown transparent liquid.
2. Solubility: easily soluble in water and dilute alcohol, insoluble in anhydrous alcohol and glycerin
storage method
1. It should be stored in a cool, ventilated, dry and clean warehouse. During transportation, it should be protected from rain and scorching sun, and deliquescence should be prevented.
2. Be careful when loading and unloading to prevent damage to the package. The storage period of liquid products is half a year, and the storage period of solid products is one year.
The flocculation effect of poly (poly) aluminum chloride is as follows:
a. Strong electrical neutralization of colloidal substances in water.
b. Excellent bridging adsorption of hydrolyzate to suspended solids in water.
c. Selective adsorption of soluble substances.
Polyaluminum chloride is an inorganic polymer coagulant, which is produced by the bridging effect of hydroxide ions and the polymerization of polyvalent anions. It is mainly determined by the working principle of the pressure atomizer.
The main purpose
1. Water treatment agent is mainly used for the purification of drinking water, industrial sewage and urban sewage, such as iron removal,adioactive pollution removal, floating oil removal, etc. Also used for industrial wastewater treatment, such as printing and dyeing wastewater. Also used in precision casting, medicine, paper rubber, leather, petroleum, chemicals, dyes.
2. Polyaluminum chloride is used as a water treatment agent in surface treatment.
3. Cosmetic raw materials.
Properties and Stability
1. It has the properties of adsorption, coagulation and precipitation, and the stability of polyaluminum chloride is poor. Toxicity and protection are corrosive. If accidentally splashed on the skin, rinse immediately with water. Production staff should wear overalls, masks, gloves, and long rubber boots. The production equipment should be closed, and the workshop should be well ventilated.
2. Corrosive. When heated to above 110°C, it decomposes, releases hydrogen chloride gas, and finally decomposes into alumina; reacts with acid to depolymerize, reduces the degree of polymerization and basicity, and finally becomes aluminum salt. The degree of polymerization and alkalinity can be increased by the action of alkali, and finally aluminum hydroxide precipitates or aluminates can be formed; when mixed with aluminum sulfate or other polyvalent acid salts, it is easy to form precipitates, which can reduce or completely lose the coagulation performance.
a. The purified water quality is better than that of aluminum sulfate flocculant, and the cost of purified water is 15-30% lower than that.
b. The formation of flocs is fast, the settling speed is fast, and the processing capacity is larger than that of traditional products such as aluminum sulfate.
c. The alkalinity of the consumed water is lower than that of various inorganic flocculants, so no or less alkaline agent can be added.
d. The suitable source water can be condensed in the range of PH5.0-9.0.
e. Low corrosiveness and good operating conditions.
f. The solubility is better than that of aluminum sulfate.
g. The increase of salt in the treated water is small, which is beneficial to ion exchange treatment and high-purity water production.
h. The adaptability to source water temperature is better than that of inorganic flocculants such as aluminum sulfate.
