This product is strong cationic poly electrolyte, appearance is colorless to light yellow viscous liquid. Safety, non-toxic, easy to dissolve in water, non flammable, strong cohesion, good stability, hydrolysis stability, not gel, the pH value is not sensitive to change, there is resistance to chlorine. The freezing point is about -2.8 degree, the specific gravity is about 1.04g/cm3,
the decomposition temperature is 280- 300 degree
It is used in waste water treatment as a primary organic coagulant which neutralizes negatively charged colloidal material and reduces sludge volume compared with inorganic coagulants
2-Pulp and paper industry
It is used for controlling disturbing substance in the paper making process
It provides superior fixing of pitch from mechanical pulp and latex from coated broke. Used in the short circulation of a paper mill to enhance retention and dewatering. In addition It can be used to improve the efficiency of disk fillers and floaters and for cationization of fillers to provide maximal filler retention
It can also be used as a flocculants to improve soap separation process in the evaporation plant of kraft pulp mills thus contributing higher tall oil yield
It is used as flocculants in water purification
It is very effective in flocculating, decoloring,killing algae and removing organics such as humus, little is needed to produce large flocs. Rapid precipitation and low turbidity residue
4-Mining and oil industry: It is used in treating all kinds of mineral slurry, also can be used in treating the oil water separator, oil dehydration and oily wastewater in oil refinery and oilfield etc..

Packing: IBC DRUM
Quantity: 1FCL 18mt ( 18 IBC DRUM )
APPLICATION METHOD :
1. When used alone, it should be diluted to the concentration of 0.5%-0.05% (based on solid content).
2. In dealing with different source water or waste water, the dosage is based on the turbidity and the concentration of the water. The most economical dosage is based on the trial.
3. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the other chemicals in the water and the flocs can not be broken.
4. It is better to dose the product continuously.
