Anionic Polyacrylamide( APAM )
Product form: White powder or granule
It has the properties of flocculation, thickening and water absorption. Soluble in water to form viscous liquid. Molecular weight can be adjusted on demand.
|Solid content (%) =
|Molecular weight (10000)
|Free monomer (%) =
|Dissolution rate (hours)
Anionic polyacrylamide is mainly used in mineral processing, metallurgy, coal, food and other industries of solid-liquid separation and wastewater treatment, wastewater, steel, textile, paper industry, oil industry for drilling and extraction of three times; papermaking retention agent and reinforcing agent etc.
Cationic PAM is mainly used as city sewage and industrial wastewater treatment and sludge dewatering flocculant; papermaking retention agent and reinforcing agent; pharmaceutical, leather, printing and dyeing wastewater treatment, textile industry as fabric finishing agent.
As a highly selective flocculant, nonionic polyacrylamide was used in drilling fluid and oil field wastewater treatment and acid wastewater treatment.
Amphoteric polyacrylamide is mainly used in sludge dewatering of oil refining and chemical industry.
Product use and packaging storage
preparation of drugs
According to the characteristics of the product, in the preparation and use of the process, should pay attention to the following matters:
1, the use of concentration should not be too high, the concentration of the general formulation in the range of 0.05%-0.5%;
2, the product should be dissolved, add half dissolved in water tank, and then stirring slowly adding medicament, the medicament is added to disperse rapidly, prohibit direct dumping, prohibit the first drug with water, to prevent a large insoluble;
3, the preparation of water with salt free neutral water, usually with tap water, no special requirements;
4, stirring speed and strength to be appropriate, too small to open, will increase the dissolution time, too fast will lead to severe molecular chain rupture, reduce the use of performance;
5, the general solution at room temperature, can not be heated, if the cold winter, in order to accelerate the dissolution of the product can be heated up to 30-40 DEG C, no more than 60 degrees C, more than 60 DEG C will occur degradation, so that performance degradation;
6, dilute solution to be used now, the general storage time should not be more than 24 hours, a long time to place the product performance will decline;
7, if the emulsion products appear stratified, should be mixed after use, does not affect the use of performance.
1, emulsion products using 25KG, 50KG, 200KG or 1T plastic barrel packaging, powder products using 15KG, 20 KG, 25KG lined plastic woven bag or paper plastic composite bag packaging, can also according to user requirements packaging;
2, the emulsion products stored at room temperature, the temperature of ~40 DEG C 5. Shelf life of 6 months. Expired products such as no exception can continue to use.
3, powder products placed in a cool and dry place. Shelf life of 2 years. Expired products such as no exception can continue to use.
Polyacrylamide products are non-toxic and non corrosive products, if used in the skin, eyes or mouth, to wash in time. Suitable for washing with warm water.
Such as emulsion sprinkled on the ground should be put away, or after mixing with dry soil cleaning, and finally rinse with water. The water spilled on the ground.
