Silicone defoamer-Shanxi Shuozhou manufacturer: PAM Polyacrylamide Introduction Polyacrylamide (PAM for short) is a linear high molecular polymer, easily soluble in water, and its aqueous solution is almost non-dangerous. Non-corrosive. Solid PAM has hygroscopicity, flocculation, adhesiveness, resistance reduction, thickening, and good simultaneity. Application fields Widely used in water treatment and electric power, mining, coal preparation, asbestos products, petrochemicals, papermaking, textiles, environmental protection, etc. Technical indicators Polyacrylamide name Molecular weight (10,000) Ionity (%) PH Solid content% Residual single% Appearance Cationic polyacrylamide 600-800 10-50 1-14 ≥88 0.05 White dry powder anionic polyacrylamide 300-2200 10- 50 7-14 ≥90 0.05-0.15 White particle powder name Molecular weight (10,000) Cationic degree% Anionic degree% PH Solid content% Appearance Zwitterionic polyacrylamide 500-5 1-14 ≥90 White powder Product type Anionic polyacrylamide ( PAMA) Molecular weight 3-22 million Cationic polyacrylamide (PAMC) Molecular weight 6-8 million Nonionic polyacrylamide (PAMN) Molecular weight 5-6 million Zwitterionic polyacrylamide (PAM-CA) Molecular weight 5-17 million Anionic polypropylene Amide is mainly used as a flocculant: for suspended particles, sewage with coarser, high concentration, positively charged particles, neutral or alkaline water pH, because the anionic polyacrylamide molecular chain contains quantitative polar groups that can absorb water The suspended solid particles make the particles bridge to form large flocs. Therefore, it accelerates the sedimentation of particles in the suspension, has a very obvious effect of speeding up the clarification of the solution, and promoting filtration. This product is widely used in the treatment of chemical industrial wastewater and liquid waste, and municipal sewage treatment. Water treatment in tap water industry, purification of high turbidity water, Shen Qing, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry, etc.; Used in petroleum industry, oil recovery, drilling mud, waste mud treatment, prevention of water channeling, friction, oil recovery, and tertiary oil recovery; widely used in textile sizing agent, slurry performance, less slurry, low fabric breakage, cloth Smooth and clean surface; used in the paper industry for retention of fillers and pigments. The loss of raw materials and the pollution; the second is the strength of the paper (including dry strength and wet strength). In addition, the use of PAM can also improve the tear resistance and porosity of the paper to improve the visual and printing performance. It is also used in food and tea. In the wrapping paper;
Other industries, food industry, used for cane juice clarification and syrup phosphorous float extraction in the production of cane sugar and beet sugar. Enzyme fermentation broth flocculation and clarification industry, also used in the recovery of feed protein, with good performance, the recovered eggs have no adverse effects on the survival rate, weight gain, and egg production of chickens, synthetic resin coatings, civil construction grouting materials, water shutoff, building materials industry , Cement, construction industry adhesives, joint repair and water plugging agents, soil improvement, electroplating industry, printing and dyeing industry, etc.;
Cationic polyacrylamide Cationic polyacrylamide presents positive electricity in acidic or alkaline media. It usually has a lower molecular weight than anionic or non-ionic polyacrylamide. Its clean sewage performance is mainly due to charge neutralization. The main function of this type of flocculant is to flocculate with a negative charge, and has the functions of removing turbidity and decoloring. Cationic polyacrylamide is more effective than anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt in wastewater treatment in alcohol factories, MSG factories, sugar factories, meat products factories, beverage factories, printing and dyeing factories, etc. Times or tens of times, because this type of wastewater generally has negative charges. At present, the use of water-soluble azo initiator AIBA, etc., has been able to increase its molecular weight to more than tens of millions.
Cationic polyacrylamide is suitable for high-speed centrifuges, belt filter presses, plate and frame filter presses and other special sludge dewatering machinery. It has fast formation of flocs, flocs, resistance to shearing, good agglomeration, and easy to filter Features such as cloth peeling. Therefore, the dehydration rate is high, the filter cake has low liquid content, and the amount is small, which can greatly increase the user's use cost. It can also be used to separate and purify the turbidity contained in medium-concentration sulfuric acid, etc. Therefore, the product is widely used in sludge dewatering treatment in urban sewage treatment plants, breweries, food plants, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industries and cosmetics.
Non-ionic polyacrylamide is mainly used as a flocculant: because its molecular chain contains quantitative polarity genes, it can absorb solid particles suspended in water and form large floccules between the particles. It accelerates the sedimentation of particles in the suspension, has a very obvious effect of speeding up the clarification of the solution, and promoting filtration. It is widely used in the treatment of chemical industrial wastewater and waste liquid and municipal sewage treatment. Especially when the sewage is acidic, this product is suitable. It can be used in conjunction with inorganic flocculants such as polyiron, polyaluminum and other inorganic salts.
It is widely used in petroleum industry, oil extraction, drilling mud, waste mud treatment, prevention of water channeling, friction, oil recovery, and tertiary oil recovery.
Used for textile sizing agent, sizing performance, less sizing, low rate of fabric breakage, smooth cloth surface.
Used in the paper industry, it is the retention rate of fillers and pigments. The loss of raw materials and the pollution; the second is the strength of the paper (including dry strength and wet strength). In addition, the use of PAM can also improve the tear resistance and porosity of the paper to improve the visual and printing performance. It is also used in food and tea. In wrapping paper.
Zwitterionic polyacrylamide is mainly used as profile control and water shutoff agent in oilfields, combined with crosslinking agent, agent, and coagulant to produce coagulant and water shutoff agent with important polymer gel and resin gel. It plugs formation pores and cracks through attachment and physical plugging. The ratio can control the gel time to adapt to different geological conditions. Treatment of various oil, inorganic, sewage, and complex sewage. In sewage with fluctuating pH. Used for sludge dewatering. Used in papermaking additives.
