Properties and Purpose:

DF--3 composite water treatment agent is composed of organic phosphonate, carboxylic acid copolymer and metal corrosion inhibitor. Its cost performance is outstanding, and it has more advantages in industrial circulating water.

Good scale inhibition effect and strong corrosion inhibition.

Quality index:

Appearance:	Transparent or light yellow liquid
Solid contents≥	25
PH (1% solution)	3.0--4.0
Density g/cm³ ≥	1.10
PO₃^-3 (m/m)％ ≤	0.8
PO₄^-3 (m/m)％	0.15
Organic phosphonate (m/m)％（PO₄^-3）	7.0±0.5

Usage:

The chemical is applicable under normal operation, which can be added to circulating water system continuously or intermittently with maintained concentration of 40--70mg/1. When the pH value of circulating water is <8.5or M-a(Caco3)<150ml/1, the compatible usage with alleviating assistant agent is recommended.

Package and Storage:

It is kept in 25kg plastic drums in cool warehouse of ambient temperature over -2℃.

safety protection：

DF-3 compound water treatment agent is weak acid. It should avoid contact with skin and eyes and rinse with clean water after contact.
