Phosphorus-free scale inhibitor(WS B-308d）

WS B-308d phosphorus-free corrosion and scale inhibitor does not contain phosphorus. It can greatly reduce the sewage treatment cost in areas where the emission of phosphorus in sewage is strict. Because it does not contain phosphorus, the microbial reproduction in the circulating water system is reduced and reduced. The amount of bactericidal algaecide and slime stripper is used.

Project	Indicator
Exterior	Dark brown liquid
Solid content %	≥30.0
Density (20 ° C) g / cm3	≥1.10
pH (1% aqueous solution)	2.0-3.0

◇ How to use:

(1) The concentration of this product is 30mg/L, which has a good corrosion inhibition effect on water with a total hardness of 100 mg/L and a total alkalinity of 100 mg/L, for example, the water of the Yangtze River. The corrosion rate of carbon steel is less than 0.075mm/a. ;

(2) The concentration of this product is 30mg/L, which has a good corrosion inhibition effect on water with a total hardness of 300 mg/L, a total alkalinity of 200 mg/L, and a chloride ion of more than 300 mg/L. Carbon steel corrosion The rate is less than 0.075mm/a;

(3) The concentration of this product is 60mg/L, and the corrosion inhibition effect is good for the ultra-low hardness water quality conditions such as the total hardness of 50 mg/L and the total alkalinity of 50 mg/L, such as the Lancang River system;

(4) This product can be compounded with other drugs, and the concentration can be greatly reduced;

(5) When the phosphorus-free corrosion and scale inhibitor is used alone, the optimum concentration is 40-60mg/L.

◇Packing and storage:

Packed in plastic drums, 25kg per drum or as determined by the user.

The storage period is twelve months.

◇Safety and protection:

This product is acidic. Wear glasses gloves during operation to avoid contact with skin and eyes. Rinse with plenty of water after contact.
