Chemical Materials

1. Cation polyacrylamid

Description:
This product is a water- soluble high polymer.It’s not soluble in most organic solvents, with good flocculating activity, and can reduce the friction resistance between liquid.

Application Field:
1. It is mainly used for the sludge dewatering and decrease the rate of water content of sludge.
2. It can be used to treat industrial wastewater and life sewage water.
3. It can be used for papermaking to improve dry and wet strength of paper and to improve dry and wet strength of paper and to increase the reservation of tiny fibers and        fillings.

Note: our product can be made upon your special request.

 

Application Method:

1. It should be diluted to the concentration of 0.1%(based on solid content).It is better to use neutral or desalted water.
2. When making up solution, the product should be scattered evenly in the stirring water, usually the temperature is between 50-60℃.
3. The most economical dosage is based on the trial.

Package and Storage:

1. The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.The colloidal product can be packed in inner plastic bags and further in fiber plate drums with each drum containing 50Kg or 200Kg.
2. This product is hygroscopic, so it is should be sealed and stored in a dry and cool place below 35℃.
3. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.

 

2. Anionic polyacrylamide

Application Field:
1. It can be use to treat industrial wastwater and mining wastwater.
2. It can also be used as an additive of the mud materials in oil-field, geological drilling and well boring.

Application Method:

1. The produced should be prepared for the water solution of 0.1% as concentration. It is better to use neutral and desalted water.
2. The produced should be scattered evenly in the stirring water, and the dissolving can be accelerated by warming the water.
3. The most economical dosage can be determined based on a preliminary test. The pH value of the water to be treated should be adjusted before the treatment.

 

3. Nonionic polyacrylamide

Application Field:

1. It is mainly used to recycle the wastewater from clay producing.
2. It can be used to centrifugalize the tailings of coal washing and filter the fine particles of iron ore.

3. It can also be used to treat industrial wastewater.

4. Poly diallyl dimethyl ammonium chloride

Description:

This product (technically named Polydimethyl-Dislkelen-Ammonium Chloride) is cationic polymer and it can be completely dissolved in water.

 

Application Field:


1. The polymer body contains strong cationic group radical andactivated-adsorbent group radical which can destabilize and flocculate thesuspended solids and the negative-charged water soluble matters in the wastewater through electro-neutralization and bridging adsorption. It is veryeffective in flocculating, decoloring, killing algae and removing organics.

2. The product enjoys small dosage but can cause big flocs, rapid precipitationand low turbidity residue, and it can also produce small amount of sludge. Itis adaptable to wide range of pH value, between 4.0 and 10.0.

3. It is smelless, tasteless and harmless. It can be widely used to treatsource water and sewage water.
 

Specifications

Appearance

Colorless or light yellow colloid

PH (1% water solution)

3.0 ~ 6.0

Solid content %

40 ± 1

Note: our product can be made upon your special request.

 

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 basedon the turbidity and the concentration of the water. The most economical dosageis based on the trial.
3. The dosing spot and the mixing velocity should be carefully decided toguarantee that the chemical can be mixed evenly with the other chemicals in thewater and the flocs can not be broken.
4. It is better to dose the product continuously.

Package and Storage:
1. It is packaged in plastic drums with each containing 50kg and 200kg.
2. Sealed and stored in cool place, avoid solarization.
3. This product will appear layer after a long-term storage, but the effectwill not be affected with stir.
