Biqing water free samples, technical support, Tracking service, your satisfaction, my pleasure ......... polyacrylamide (APAM) formula [CH2CH (CONH2)] m- [CH2CH (COONa)] n, is an organic polymer, the appearance of white granules or powder, mainly used as flocculants, has good water solubility, dissolution fast, small dosage, good effect, such as a series of advantages, for suspended particles with a positive charge, water pH is neutral or alkaline water, because of the anion Polyacrylamide molecular chain containing a certain amount of polar groups can absorb solid particles suspended in water, so that the bridge between the particles to form large flocs, and therefore have accelerated sedimentation of particles in suspension, a clear solution to accelerate and promote filtration and other effects. Anionic polyacrylamide widely used in chemical waste, waste water treatment, municipal sewage treatment, water treatment, high turbidity water purification, clarification, coal, mineral processing, metallurgy, steel, zinc, aluminum industry, electronic industry and other water deal with. Other uses of anionic polyacrylamide: 1 for the oil industry, oil, drilling mud, waste mud treatment, to prevent water channeling, reduced friction, enhanced oil recovery, EOR has been widely used. 2. For the textile sizing agent, slurry stability performance, low drop-pulp, fabric breakage rate, clean cloth. 3. 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 anionic polyacrylamide can also improve the paper tear resistance and porosity to improve visual and print performance , but also for food and tea packaging. 4. Other industries, food industries, for cane sugar, beet sugar production juice and syrup clarification float extract phosphorus. Clarification enzyme fermentation industry, but also for the recovery of feed protein, stable quality, good performance, the recovery of protein powder to increase the survival rate of chickens and weight gain, no adverse effects on egg production, synthetic resin coatings, construction grout block water, building materials industry, improve the quality of cement, construction adhesives, caulking repair and blocking agent, soil improvement, electroplating industry, printing and dyeing industry. Anionic polyacrylamide using the methods and precautions: 1. When used, should be different for different applications and process wastewater to determine the optimum dosage by small-scale test in order to achieve the best results, first dubbed a certain concentration of a homogeneous solution (0.1%) diluted into a dilute solution after use. 2. Preparation of polymer flocculant solution should be in enamel, galvanized, aluminum or plastic drums were better. 3. The solution should pay attention to the product evenly and slowly added with stirring, to avoid a large group knot fast, suitable for solution prepared at room temperature, the appropriate heating (<60 ℃) can accelerate into a solution. Should avoid prolonged drastic mechanical shear, so as not to reduce the use of effects. 4. The general solution that is ready to use with, try to avoid using the next day. 5. The solid product to avoid scattered on the ground, to prevent moisture absorption after the product becomes so slippery.
