Coal flotation agent

Beijing Jia Rui Lin Water Treatment Technology Co., Ltd. is a development, production, operation of water treatment technology and its products, specialized companies, the company production base for many years in the domestic experts and scholars water treatment units and relevant guidance, extensively absorb domestic application foreign advanced technology, relying on local resources, production and processing of various water purification materials, stable and reliable product performance and reasonable price. Extensive application in the domestic market and exported to Southeast Asia via Hong Kong, deeply domestic and foreign users. The main products are: PAC (PAC), polyacrylamide (PAM), PFS (PFS), ferric chloride (PAFC), bleaching flocculants, oil-water separator, a polymerization catalyst, coagulant, sulfuric acid ferrous 18,210,484,665 room CERCON Description: coal washing special polyacrylamide PAM is a more professional polyacrylamide. In fact, just inside the chemical composition do a bit of adjustment. Coal washing coal washing special dedicated polyacrylamide polyacrylamide, polyacrylamide than several times better than in the coal washing filter press, or in groundwater is discharged from the effect is very obvious, or so its response time is five seconds can see the effect of precipitation, so that the causes of many coal mines select flocculant of coal washing. In the coal was mined coal usually contain some impurities whole, the separation efficiency can be improved by the addition of coal and impurities flotation agent. Out of coal flotation tail coal settlement. Then by sedimentation, filtration or centrifugation round ending coal coal. Acrylamide in the settlement process, thereby facilitating solid-liquid separation. And then sent to the thickener, the water recovered from the thickener overflow and recycling. Powdered coal recovered through filtration and centrifugation. In the process of filtration and centrifugation polyacrylamide added again increase the separation efficiency. To user needs in this regard we produce a coal washing flocculant for different coal mine have better results, but also greatly reduces the amount of administration. Technical indicators: Item Unit Item Unit Index Appearance - white granular powder filtration ratio - ≤1.5 Solid content% ≥90 viscosity mpa.s ≥38.0 molecular Wan 600-1800 residual monomer% ≤0.05 intrinsic viscosity - 17.5 19.4 screen factor - ≥20.0 dissolution rate of hydrolysis of 22.5-27.5% ≤1.5 hour specific purposes: coal washing special PAM PAM in the coal industry, coal washing waste water, coal slurry preparation plant, coal-fired power plants and other surface washing waste is a mixture of water and fine coal, its main feature is high turbidity and fine solids particle size, solid particle surface more negative charge, the same charge repulsion between these particles remains dispersed state in water, gravity and Brownian motion effects; the interaction Slurry interface between the solid particles (such as adsorption, dissolution, compounds, etc.), the nature of coal washing wastewater is quite complex, not only has the nature of the suspension, but also has the nature of colloids. Not a lot of coal washing waste water discharge standards, resulting in water pollution, river silting, slime loss to the country caused great economic loss, but also makes the coal industry is more scarce water resources, severely restricts the development of coal production. Therefore, the development coal washing waste water efficiently handle new technology has important significance. Coal washing special polyacrylamide make rapid sedimentation of slime water in the pool was concentrated, to ensure that qualified washing with pressure filtration slime production, so that the production efficiency of economic operation, you must select the appropriate flocculant to enhance the slime water treatment. Through years of practice it has proved that polyacrylamide to the slime water treatment better, to speed up the settlement of slime and help filter press production. Usage: 1, when used, dubbed solution concentration of 0.01% -0.05%, to use neutral salts debris-free water is appropriate. 2, when dissolved, the anionic polyacrylamide (APAM) products even thrown into stirred water, stir speed control in 100 ~ 300rpm. Proper heating (<60 ℃), can accelerate the dissolution. 3, adjusting the PH value of liquid to be treated, anionic polyacrylamide (APAM) product fully play its role, through test PH value and select the optimal amount of products in this series. 4, the addition of anionic polyacrylamide (APAM) product solution, should speed up the mixing liquid to be treated, after the floc occurs, slow-speed stirring, to facilitate and accelerate the growth of the flocs settling. Note: 1, coal washing special PAM PAM for treatment of sewage slime, must add the appropriate amount of flocculation can effectively play its role. Can be determined by testing in accordance with slime and slime - water treatment process chosen. Major cause precipitation amount of slime slow, concentrated overflow easily exceeded, can not guarantee that the required recycled water index. 2, the amount of excess, although accelerated sedimentation rate slime, but could easily lead to concentrated underflow concentration is too high, the amount of excess concentrated underflow density sometimes make up to 700g / L or more, and increase the underflow polyacrylamide content, so that the underflow transport and pressure filtration adversely, in the filter press cake briquettes unloading easy to fall off, but also caused a waste of Pharmacy, generally concentrated underflow density requirements 500g / L, to meet the filter press production. 3, coal washing polyacrylamide special caution must be effectively dispersed and dissolved, to avoid rapid dissolution of the powder surface caused by the interaction between the particles adhere, resulting in a failure to dissolve the particles inside "fish eye." 4, the flocculant dissolved poor storage stability, should be used within 24 hours after the dissolution, if after 2-3 days of viscosity decrease caused by the dysfunction. Packaging and storage: 25kg / bag (lined with plastic bag as plastic coated paper bags). This non-toxic, pay attention to moisture, rain, avoid sun exposure.
