【Product description】

30% polyaluminum chloride is a kind of inorganic polymer coagulant. Due to the bridging effect of hydroxide ion and polymerization of polyvalent anions, it is a kind of inorganic polymer water treatment agent with larger molecular weight and higher charge.

【1、Product Introduction】

30% polyaluminum chloride (abbreviated as polyaluminum chloride or polyaluminum)

Polyaluminium Chloride, abbreviated PAC

[Molecular formula] Al2O3

[Technical standard] The product quality conforms to the national GB15892-2009 standard for drinking water polyaluminum chloride and the national GB/T22627-2008 standard for industrial polyaluminum chloride.

Action mechanism of 30% polyaluminum chloride

30% polyaluminum chloride is a kind of inorganic polymer coagulant. Due to the bridging effect of hydroxide ion and polymerization of polyvalent anions, it is a kind of inorganic polymer water treatment agent with larger molecular weight and higher charge. Molecular formula: ALn(OH)mCL(3n-m) 0 < m < 3n, its coagulation behavior is as follows:

1, the strong electric neutralization of colloidal substances in water.

2. Excellent bridging adsorption of hydrolysates on suspended solids in water.

3. Selective adsorption of dissolved substances.

Packaging, transportation and storage of 30% polyaluminum chloride

Polyaluminum chloride (solid) for drinking water shall be double-packed, the inner package shall be polyethylene film bag, the thickness shall be no less than 0.05mm, the packing volume shall be larger than the outer package, and the performance and inspection method of the outer package shall comply with the provisions of GB/T8946. The net weight of each bag is 25kg, 50kg(depending on customer requirements).

Polyaluminum chloride (liquid) for drinking water is packed in polyethylene plastic drums. Polyaluminum chloride (liquid) for drinking water can also be shipped in storage tanks when the user needs it.

3 Polyaluminum chloride for drinking water should be covered in transit to avoid rain and moisture: and keep the package complete and clear label.

Polyaluminum chloride for drinking water should be stored in a ventilated and dry warehouse. The shelf life of liquid products is 6 months, and the shelf life of solid products is 12 months.
