Does poly aluminium chloride can be applied in paper making?
- polyaluminium chloride (PAC) can be applied in paper making. In the paper industry, PAC is often used as a coagulant in the papermaking process. It helps to remove impurities and suspended particles from the pulp, which results in a clearer and cleaner paper product.
- PAC is also used in the production of paper sizing agents. Sizing agents are chemicals that are used to improve the water-resistance and printability of paper. PAC can be used as a sizing agent because it forms a strong and stable bond with cellulose fibers, which are the main component of paper.
- Overall, PAC is a versatile and useful chemical that can be applied in various industries, including the paper making industry.
PAC Product Introduction:
This product is a kind of inorganic polymer flocculant. Mainly through compression double, adsorption electricity neutralization, adsorption Bridges, sediment trap, etc mechanism function, make edema subtle aerosols and colloidal ions off firm, gathered, flocculation, coagulation, precipitation to purify the treatment effect.
The characteristics of Polyaluminium chloride are:
- It is a spray dryer type.
- It is utilized for both drinking water and wastewater treatment purposes.
- It appears as a solid powder with a yellow color.

Polyaluminum Chloride Packing&Storage:
25kg/PP woven bag with an inner plastic bag
The product shall be sealed and stored in a dry and ventilated place to prevent it from rain, high temperature, and strong sunlight. The shelf life of the product is 24 months.
Polyaluminium Chloride Advantages:
-
Polyaluminium chloride outperforms other organic flocculants in purifying low-temperature, low-turbidity, and heavily organic-polluted raw water. This results in a treatment cost reduction of 20%-80%.
-
The quick formation of large-sized floc (especially at low temperatures) and rapid precipitation service life of cellular filter of the sedimentation basin are facilitated by this chemical.
-
In comparison to other flocculants, a smaller dosage of Polyaluminium chloride is required to improve the quality of treated water.
-
Polyaluminium chloride displays wide adaptability to different water temperatures (in the summer and the winter) and regions (in the south and the north of China).
-
It is compatible with the automatic dosing device of alum.
-
Polyaluminium chloride can function over a wide range of pH values (5-9) and can decrease the pH value and basicity after processing.
PAC Usage:
1. The user can allocate remedy concentration by test and determine the optimum dosage according to different to be added after they are dissolved and diluted.
2. The dilution ratio of liquid product is 5-50% and the dilution ratio of the solid product is 2-20%.
3. The liquid product dosage is 3-40kg/1000 tons of water and solid product dosage is 1-15kg/1000 tons of water.
4. The amount of specific dosing is based on coagulation tests and experiments.
