Silicone defoamer-Hulunbeier manufacturer: Beijing Shuibiqing Environmental Technology Co., Ltd. can meet the requirements of various fields in waste liquid treatment, sludge concentration and dewatering, beneficiation, coal washing, papermaking, etc. The coal plant's treatment of slime water generally adopts the "cyclone-thickener-filter press (slime sedimentation tank)" treatment process. Under normal circumstances, it is purchased machine polymer flocculant (polyacrylamide). The high-molecular flocculant interacts with slime particles or slime colloids to neutralize the electrical properties and surface energy of the slime surface, making the slime particles agglomerate and settle. The molecular weight of polyacrylamide is generally between one million, and flocculants of different molecular weights should be used for slime water with different particle sizes. Polyacrylamide can be divided into three types: anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide. When using polyacrylamide for water treatment, it is necessary to ensure that the type is consistent with the pH value of the slime water. Anionic polyacrylamide is suitable for alkaline slime water.
Cationic polyacrylamide is suitable for acidic slime water. Anionic and cationic polyacrylamide are mixed and used, and the flocculation and sedimentation effect of slime water is better.

High-purity polyacrylamide label: High-purity polyacrylamide produced by high-purity poly is a new type of water purification product developed to adapt to the wide range of applications of polyacrylamide products. It is aimed at different situations to make up for some shortcomings, thereby increasing the performance of polyacrylamide-producing a synergistic effect. Retention aid function: In papermaking, water must be filtered out as much as possible to leave paper fibers and fillers. This is similar to the principle of sewage sludge treatment, so adding polyacrylamide will help filter retention. It shows that for different paper products, based on dry pulp calculation, adding 0.1-3% polyacrylamide can produce 2-8% paper output, and because of the loss of fillers and short fibers, it also reduces the subsequent sewage treatment load. Sewage treatment: Polyacrylamide enlarges the alum through bridging, which is much more effective than using polyaluminum chloride and other chemicals alone. Cationic polyacrylamide label: Cationic polyacrylamide is suitable for use as a flocculant. Mainly used in industrial solid-liquid separation.
