Non ionic polyacrylamide (NPAM) is a water-soluble polymer electrolyte.
Non ionic polyacrylamide is a water-soluble polymer electrolyte formed by the free radical polymerization of acrylamide monomers using a series of initiators in aqueous solution. Used as a flocculant in water treatment processes. The mechanism of action of non-ionic polyacrylamide lies in the presence of a large number of polar groups in its molecular chain. Polar groups can adsorb solid particles in water, forming bridges between particles or aggregating particles into larger flocs through charge neutralization.
1、 Characteristics of non-ionic polyacrylamide:
Non ionic polyacrylamide has good water solubility and can be completely dissolved even in cold water. A small amount of non-ionic polyacrylamide can produce a great flocculation effect. Under certain conditions, it can be used in combination with inorganic flocculants such as polymeric ferric sulfate, polymeric chloride, and iron salts to produce excellent flocculation effects.
2、 Application of non-ionic polyacrylamide:
Bi Lang non-ionic polyacrylamide is mainly used for the purification treatment of acidic to weakly alkaline wastewater. The treatment of industrial wastewater mainly involves flocculation, sedimentation, and clarification. Such as the treatment of papermaking and pulp wastewater, wastewater treatment in mineral processing and metal refining processes, and wastewater treatment in steel and stone factories.
1. Non ionic polyacrylamide has a special effect on organic colloidal suspensions, which can quickly promote sludge dewatering and filtration. It is not easy to loosen during pressure filtration.
2. Applied in the treatment of organic wastewater, such as electroplating wastewater, printing and dyeing wastewater, oil and fat wastewater, alcohol wastewater, waste liquid from monosodium glutamate factories, sugar factory wastewater, etc., flocculation and sedimentation have good application effects.
3. In terms of papermaking, it can be used to improve the dry and wet strength of paper and enhance its tensile strength.
4. Used as an industrial additive: such as applied to oilfield chemical additives.
3、 Precautions for the use of non-ionic polyacrylamide:
1. Contact personnel must wear protective equipment when using non-ionic polyacrylamide, and the skin contact area should be immediately washed with clean water.
2. Maintain a dry bath in the workplace and avoid sprinkling non-ionic polyacrylamide on the ground. In case of wet or slippery conditions, it should be cleaned promptly to prevent slipping and falling.
3. Try to prevent moisture absorption and exposure to sunlight.
4、 Bi Lang non-ionic polyacrylamide technical services:
Shanghai Bilang Environmental Protection Technology Co., Ltd. provides users with comprehensive technical services for the selection, small-scale experiments, and factory trials of non-ionic polyacrylamide products.
5、 Packaging and transportation of Bi Lang non-ionic polyacrylamide:
1. 25KG composite bag or 750KG large package
6、 Non ionic polyacrylamide NP usage process:
1. When using, prepare a 0.1% concentration aqueous solution of non-ionic polyacrylamide and use neutral water that does not contain salt impurities.
2. Evenly sprinkle this series of products into the stirred water, and control the stirring speed at 100-300rpm. Moderate heating (<60 ° C) can accelerate dissolution
3. Select the optimal pH value and dosage of cationic polyacrylamide through experiments
5. When adding non-ionic polyacrylamide, the mixing with the treated liquid should be accelerated. After the appearance of flocculants, the stirring speed should be slowed down to promote the growth of flocculants and the accelerated settling of the treated liquid.
