Poly aluminum chloride laboratory chemicals and reagents

 physical chemistry:

Polyaluminum chloride has the properties of adsorption, coagulation, precipitation, etc. It has poor stability and is corrosive. If it is accidentally splashed on the skin, it should be rinsed off immediately with water. Production personnel should wear overalls, wear masks, gloves, and long rubber boots. Polyaluminum chloride has good spray drying stability, wide water area, fast hydrolysis rate, strong adsorption capacity, large strontium flower formation, fast sedimentation, low effluent turbidity and good dehydration performance. Spray drying products ensure safety and reduce water accidents, making them safe and reliable for drinking water. Therefore, polyaluminum chloride, also referred to as high-efficiency polyaluminum chloride, high-efficiency PAC or high-efficiency spray-drying polyaluminum chloride. Polyaluminium chloride is suitable for raw water of various turbidity, and has a wide pH range, but its sedimentation effect is far less than that of polyacrylamide.

concentration ratio:

 When the solid polyaluminum chloride is diluted into a liquid, the first dose should be determined according to the original water condition. When polyaluminum chloride is used in production, it may be mixed and dissolved in a mass ratio of polyaluminum chloride solid water: 1:9 to 1:15. A solution having an alumina content of less than 1% is easily hydrolyzed, which lowers the use effect, and the concentration is too high to be easily added. After the application of the medicinal agent, if there is less sputum in the sedimentation tank and the turbidity is large, the dosage is too small; if the sedimentation pond is large and upturned, the dosage is too large and should be adjusted appropriately.

color type

The color of polyaluminum chloride is generally white, yellow, and tan, and the polyaluminum chloride of different colors is also quite different in application and production technology. The polyaluminum chloride with a content of tri-alumina between 27% and 30% in the national standard is mostly a yellowish, yellowish, pale yellow solid powder. These types of polyaluminum chloride have good water solubility, accompanied by physical and chemical changes such as electrochemistry, coagulation, adsorption and precipitation in the process of dissolution. Floc formation is fast and coarse, high activity, fast precipitation, and high turbidity water. The purification effect is obvious.

White polyaluminum chloride is called high-purity iron-free white polyaluminium chloride, or food-grade white polyaluminium chloride. It is the highest quality product compared with polyaluminum chloride. The main raw material is high quality hydrogen peroxide. The production process of aluminum powder and hydrochloric acid is the most advanced technology spray drying method in China. White polyaluminum chloride is used in paper sizing agents, sugar bleaching clarifiers, tanning, medicine, cosmetics and precision casting and water treatment.

The raw materials of yellow polyaluminium chloride are calcium aluminate powder, hydrochloric acid and bauxite, which are mainly used for sewage treatment and drinking water treatment. The raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid, and a little aluminum. Calcium acid powder, the process adopted is a plate and frame filter press process or a spray drying process. For the treatment of drinking water, the country has strict requirements for heavy metals, so both raw materials and production processes are better than brown polyaluminum chloride. The yellow polyaluminum chloride is generally produced by drum drying production or spray tower drying, and has two solid forms of flakes and powders.

The raw materials of the brown polyaluminum chloride are calcium aluminate powder, hydrochloric acid, bauxite and iron powder. The production process uses the drum drying method, which is mainly used for sewage treatment. Because the iron powder is added inside, the color is brown. The more the iron powder is added, the darker the color is. If the iron powder exceeds a certain amount, at some time, Known as polyaluminum ferric chloride, it has excellent effects in sewage treatment.

Superior nature

PAC polyaluminium chloride has good stability due to spray drying, adapts to wide water area, fast hydrolysis rate, strong adsorption capacity, and has the advantages of large sputum flower, fast dense sedimentation, low effluent turbidity and good dehydration performance. Under the circumstance, the dosage of spray-dried polyaluminium chloride is reduced, especially in the case of poor water quality, the spray drying product dosage can be reduced by half compared with the drum-dried polyaluminium chloride, which not only reduces the labor intensity of workers, but More important is to reduce the cost of water for users. In addition, spray drying products ensure safety and reduce water accidents, making them safe and reliable for drinking water.

Polyaluminium chloride, referred to as high-efficiency polyaluminum chloride, or high-efficiency PAC. It adopts the most advanced production technology and uses high-efficiency high-quality raw materials to react and polymerize. Production is carried out in accordance with the requirements of the national standard GB15892-2009. Polyaluminum chloride is processed by a spray drying process. Therefore, it can also be called high-efficiency spray-drying polyaluminum chloride.

Polyaluminum chloride composition:

Mainly aluminum oxide or aluminum oxide, molecular formula: [Al2(OH)nCl6-n·xH2O]m (m≤10, n=1~5) is a high-charged polymeric cyclic chain with Keggin structure, colloidal in water And the particles have a high degree of electrical neutralization and bridging, and can strongly remove micro-toxic and heavy metal ions, and the properties are stable. Inspection method: According to the international GB15892-2003 standard inspection. Also known as basic aluminum chloride, polyaluminum chloride is abbreviated as PAC, also known as polyaluminum chloride, composite polyaluminum chloride, basic aluminum chloride.

Polyaluminum chloride technical indicators:

The flocculation of poly(a) aluminum chloride is as follows:

a, strong electrical neutralization of colloidal substances in water.

b. Excellent bridging adsorption of hydrolysate on suspended solids in water.

c. Selective adsorption of dissolved substances.

Polyaluminium chloride is an inorganic polymer coagulant. Characteristics of inorganic polymer water treatment agents with large molecular weight and high charge due to the bridging action of hydroxide ions and the polymerization of polyvalent anions. It is mainly determined by the working principle of the pressure atomizer.

Performance analysis
a. The purified water quality is better than the aluminum sulfate flocculant, and the clean water cost is 15-30% lower than that.

b. The formation of floc is fast, the sedimentation speed is fast, and the processing capacity of traditional products such as aluminum sulfate is large.

c. The alkalinity in the consumed water is lower than that of various inorganic flocculants, so that the alkali agent can be administered without or with little.

d, the adapted source water PH5.0-9.0 range can be agglomerated.

e, low corrosivity and good operating conditions.

f, solubility is better than 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. Adaptability to source water temperature is superior to inorganic flocculants such as aluminum sulfate.

Polyaluminum chloride forms are divided into two types

a. Liquid polyaluminum chloride is an undried form, which has the advantages of no dilution, convenient loading and unloading, and relatively cheap price. The disadvantage is that the tanker is required for transportation, and the unit transportation cost is increased (equivalent to 2-3 tons of liquid per ton of solid). More suitable for users within 100 km.

b. Solid polyaluminum chloride is a form of liquid polyaluminum chloride after drying. It has the advantage of convenient transportation. It does not require a tanker. The disadvantage is that it needs to be diluted during use to increase the working intensity.
