L Long anionic polyacrylamide called acrylamide is widely used in oil exploration, water treatment, textile, printing and dyeing, paper, mineral processing, coal washing, medicine, sugar, farming, building materials, agriculture and other industries. Known as the "Better Business additives", and also "universal product," said. L Long anionic polyacrylamide major technical indicators: ※ Appearance: white granular ※ Solid content: ≥99.8% ※ MW: 600-2200 Wan ※ efficient PH: 1-14 ※ charge density: 10-40 (Mole%) ※ degree of hydrolysis : 10-35% ※ dissolution time: ≤30 minutes ※ Odor: odorless ※ thermal stability: temperature exceeds 120 ℃ easily decomposed ※ toxicity: ※ corrosive, non-toxic: no corrosive or Long anionic polyacrylamide application areas: 1. Select polyacrylamide coal washery precipitation concentrated slurry tailings filter, please use the anionic polyacrylamide, nonionic polyacrylamide, cationic polyacrylamide low. 2. Please choose the paint industry wastewater anionic polyacrylamide, nonionic polyacrylamide. Paint wastewater treatment, the traditional method is to direct the mixed wastewater coagulation treatment, the treatment effect is not ideal, the water quality is unstable, difficult to meet emission standards. 3. Fees liquid dairy industry biological treatment, sludge treatment, select cationic polyacrylamide. 4. treatment of electroplating wastewater containing cyanide oxides chosen anionic polyacrylamide, nonionic polyacrylamide, cationic polyacrylamide low. 5. copper mining tailings waste water treatment selection anionic polyacrylamide, low cationic polyacrylamide, nonionic polyacrylamide. SHENGLONG anionic polyacrylamide Features: anionic polyacrylamide, since it has: 1, to clarify the purification; 2, promote sedimentation; anionic polyacrylamide Picture 3, filtered promoted; 4, the thickening effect and other effects. In wastewater treatment, sludge dewatering, mineral processing, coal washing, paper, etc., can fully meet the requirements of various fields. Coal washing wastewater treatment plan: a "cyclone - concentrator - press (slime sedimentation)" under the Coal slime water treatment in general processes. Under normal circumstances are purchasing machine polymer flocculant (polyacrylamide). Polymer flocculant and slime slime colloidal particles or contact role, and in the power of slime surface, reducing the surface energy, the agglomerated particles precipitated slime. Molecular weight polyacrylamide generally between one million, consisting of different size slime water to choose different molecular weight flocculant. PAM can be divided into anionic polyacrylamide, cationic polyacrylamide and nonionic polyacrylamide three types. Using polyacrylamide water treatment time, to ensure that the type of slime water pH match, anionic polyacrylamide suitable alkaline slurry water, cationic polyacrylamide suitable acidic slime water, anionic and cationic polyacrylamide mixed, slime water flocculation better. Anionic polyacrylamide or Long Features: 1, water-soluble, it can be completely dissolved in cold water. 2, add a small amount of the anionic polyacrylamide products, you can receive a great flocculation. Generally only add 0.01 ~ 10ppm (0.01 ~ 10g / m3), to be fully effective. 3, while using the products and inorganic anionic polyacrylamide flocculant (PFS, chloride, iron salts, etc.), may show greater effects. 3 action principle 1) flocculation of the principle: PAM for flocculation, the flocs species with the surface properties, especially the PH value zeta potential, viscosity, turbidity and suspension related to zeta potential of the particle surface, the particle polymerization The reason for adding surface charge opposite PAM, make the move to reduce the potential and cohesion. 2) adsorption bridging: PAM molecular chain is fixed on different surfaces of the particles, forming bridges between the polymer particles, the particles form aggregates and sedimentation. 3) surface adsorption: adsorption of polar groups of various particles PAM molecule. 4) enhancement: PAM molecular chain and dispersed through a variety of mechanical, physical, chemical and other effects, the dispersed phase implicated together to form a mesh. L Long anionic polyacrylamide Scope: 1. used in textile, printing and dyeing industry. Polyacrylamide as a sizing agent textile processing, finishing agents, and can generate a supple, wrinkle-free, anti-fungal protective layer. Use of its hygroscopic characteristics, can reduce the rate of spinning yarn break Chang's. Polyacrylamide for treatment agent to prevent static electricity and fire retardant fabric. When used as auxiliaries, polyacrylamide make products for adhesion to the big, bright and high, but also as a bleaching of non-silicon polymer stabilizers. 2, is mainly used as flocculants: for suspended particles, coarse, high concentrations, positively charged particles, neutral or alkaline water PH value of water, due to the anionic polyacrylamide molecular chain containing a certain amount of the polar group can adsorption of suspended solid particles that form a bridge between the particles larger floes. It accelerates sedimentation of particles in suspension, a very significant speed up the clarified solution, which facilitates filtering effect. The products are widely used in the chemical industry waste water, waste water treatment, municipal sewage treatment. Industrial water, high turbidity water purification, Shen Qing, coal, mineral processing, metallurgy, iron and steel industry, zinc, aluminum industry, electronic industry and other treatment. 3, for the oil industry, oil, drilling mud, waste mud treatment, to prevent water channeling, reduced friction, enhanced oil recovery, EOR has been widely used. 4, for the paper industry, one is to increase filler and pigment retention rate. In order to reduce wastage and contamination of raw materials to the environment; the second is to improve the strength of paper (including dry strength and wet strength). In addition, the use of PAM can also increase the tear resistance of paper and porous in order to improve the visual and print performance, but also with food and packaging of tea. PAM PAM is a linear polymer compound, because it has a variety of lively group, with many substances affinity adsorption to form hydrogen bonds. Mostly negatively charged colloid flocculation with turbidity, bleaching, adsorption, adhesion, and other functions, suitable for dyeing, paper, food, construction, metallurgy, mineral processing, coal, oil, aquatic products processing industry and other fermented organic colloid content higher wastewater treatment, especially for dewatering municipal wastewater treatment, sludge, paper sludge and other industrial sludge.
