Characteristic Products polyacrylamide (Polyacrylamide) called PAM, commonly known as flocculants or coagulant, is a linear polymer, molecular weight between 300-2500 million, and solid appearance of the product is white powder teeth, a colorless viscous liquid gel like, soluble in water, almost insoluble in organic solvents. Application should dissolve at room temperature, when the temperature exceeds 150 °C easy to decompose. Are non-dangerous goods, non-toxic, non-corrosive. Solid PAM are hygroscopic, flocculation, adhesion resistance, reducing resistive, thickening, and good stability. The product molecules and suspended particles dispersed in solution bridging adsorption, with strong flocculation. The company's products divided into polyacrylamide: anionic, cationic, non-ionic, zwitterionic-type molecular weight of different ions with different degrees of the four products. Widely used in water treatment and metallurgy, paper, petroleum, chemical, textile, sugar, medicine, washing, dressing and other fields. Polyacrylamide mainly the following: 1 non-ionic polyacrylamide 2 cationic polyacrylamide 3 anionic polyacrylamide4 Amphoteric polyacrylamide The role of PAM principle (Profile) 1) flocculation theory: PAM for flocculating, and surface properties were floc types, especially the dynamic potential, viscosity, turbidity and suspension of the PH value of the particle surface, potentiodynamic , is the reason for adding inhibitor particles surface charge opposite PAM, can reduce the cohesion potentiodynamic. 2) adsorption bridging: PAM chains fixed in the different particle surface, the formation of polymer bridges between particles, the particles aggregate to form the settlement. 3) Surface: PAM molecules on a variety of polar groups adsorbed particles. 4) enhancement: PAM chain and scattered through a variety of mechanical, physical, chemical and other effects, the dispersed phase involved together to form a mesh, which in turn has enhanced the role. Application 1, is mainly used for flocculant: for suspended particles, coarse, high density, particle charge with Yang, PH value is neutral or alkaline water, sewage, due to the molecular chain anionic polyacrylamide contains a certain amount of polar groups on adsorption of solid particles suspended in water, so that particles form large floc bridging. It accelerated particles in suspension of settlement, there is a very obvious solution to speed up the clarification, the promotion of filtering effect. The products are widely used for chemical industry waste water, waste handling, municipal sewage treatment. Water industry, the high turbidity of water purification, Shen Qing, coal washing, dressing, metallurgy, iron and steel industry, zinc, aluminum, electronics industrial water treatment. 2, for the oil industry, oil, drilling mud, waste mud treatment, to prevent water channeling, reducing friction, enhancing oil recovery, oil recovery is widely used. 3, for textile sizing agent, slurry, stable performance, falling less pulp, fabric breakage rate is low, clean cloth. 4, for the paper industry, first increase the filler and pigment retention. To reduce wastage of raw materials and environmental pollution; the second is to improve the paper strength (including dry strength and wet strength), In addition, the use of PAM can improve the tear resistance of paper and porous, to improve the visual and print performance, also used in the food and tea packaging in. 5, other industries, food industry, for sugar cane, sugar beet juice clarification and syrup production in the extraction of phosphorus float. Enzyme broth flocculation industry, also used to feed, protein recovery, stable quality, performance, recovery of protein powder on the chicken and the survival rate of weight, no adverse effects on egg production, synthetic resin coatings, civil engineering block grouting material water, building materials industry, improve the quality of cement, construction adhesives, sealing repair and blocking agent, soil improvement, electroplating, dyeing and printing industries.
