Poly Aluminium Chloride PAC 28% Polyaluminium Chloride Fine Chemistry

Poly aluminum chloride
1. Product characteristics:
 solid yellow powder, alias poly aluminum
Polymeric aluminum, molecular formula [AL2 (OH) nc16-n]m, (M = 10; n = 5), new type of high efficiency inorganic polymer flocculent, aqueous solution is hydrolyzed between chloride between, molecular weight greater than the general inorganic flocculent
As water purifying agent, poly aluminum chloride is adaptable to various water quality, especially for high turbidity water, and its application value is within 5-9
For his water treatment effect is better, the flocculation flocculent forming block, particle dense and heavy, easy settlement, can shorten the settling time, low turbidity, Chrome, filter, filter cycle can be shortened
High alumina content and low dosage can reduce flood control cost little corrosion to pipeline
protection, use convenient, easy to store and transport, such as deliquescence, effect is the same

2. Main uses:
Aluminum chloride can sterilization, deodorization, decolonization, fluoride, aluminum, chromium, phenol, oil, turbidity, in addition to heavy metal salts, in addition to radioactive pollution substances, widely used in water purification, sewage purification, industrial water, industrial wastewater, mining, oil field injection water purification and papermaking, metallurgy, coal washing, leather and various chemical waste water treatment
For paper sizing, printing and dyeing, bleaching and dyeing accelerator in cement industry, precision casting, refractory adhesive, hardener, refining, refining glycerin syrup cloth crease, medicine, cosmetics and other industries

3. Index quality:
Note: the quality scores of ammonia nitrogen, arsenic, lead, cadmium, mercury and hexavalent chromium are all 10.0% AI203 indicators of class-I products are mandatory, class II is recommended

4. Usages:
Dilute the solid product with a solution of 5-10% of alumina, choose most PH value to add, the effect is more ideal normal turbidity water is 0.5-2kg for every 100t
When turbidity is high, the amount of investment is increased appropriately
When turbidity is low, the amount of investment is reduced appropriately
Poly aluminum chloride generated continuously in hydrolysis reaction H +, lowers the PH of water, adverse to the hydrolysis, therefore, should be appropriate to add some lime, the PH control in neutral or weak alkaline, in order to meet the needs of the hydrolysis reaction

5. Packing specifications:
Plastic film bagging, plastic woven bag, 25kg/bag

6. Precautions:
Product should be stored in ventilated and dry place (not affected by moisture) strictly prohibited to be put together with hydrochloric acid, alkali and toxic chemicals
