1. Introduction
HC-PAC10 is a white power Polyaluminium chloride produced by spray drying technology, it`s mainly used for paper industry, can also use for drinking water treatment. it`s produced by high-quality aluminium hydroxide and hydrochloric acid.
HC-PAC10 Main advantages:
1. The content of (Al2O3) % of HC-PAC10 is ≥ 30.0%.
2. The bacisity is 40-60%, other common PAC is about 80%
3. Water insoluble is ≤0.1%, other common PAC is ≤1.5%
4. The color is pure white, doesn`t contain any other heavy metals besides AL+, the corresponding solution is colourless and clarified.
5. Easily soluble in low temperature.
2. Application method
When using solid product, first add water solution to form 5-10% solution, then dilute to the needed concentration, add water in the first place and stir slowly while adding the water, the diluted solution is best used within 24 hours in order to avoid the occurrence of hydrolysis which will reduce the use of results. This product dosage depending on the source water turbidity and purification equipment, coagulation sedimentation test is needed to determine the best dosage.
3. Packing Details.
Packed by double-decked bags, each bag weights 25kg/bag, the inner layer is the plastic bag, the outer bag is woven bag.
4. Storage
This product should store up in ventilates in the dry storehouse, strictly prohibits the rain drenching, being affected with damp.
