nsultation for silicone defoamer>Secondly, it can also increase the speed of papermaking, save beating time, reduce energy consumption, and have significant economic benefits. There are several precautions when using polyacrylamide.
It is also used in tertiary oil recovery. Because the current crude oil extraction costs continue to increase, when it reaches a certain level, the company must adopt tertiary oil recovery processes to balance the price. The recovery of drilling and exploration activities in the oil extraction industry will also promote the growth of polyacrylamide consumption. During the drilling process. Polyacrylamide is used as a drilling coagulant. 3 million-6 million low molecular weight polyacrylamide can be used as a flocculation coating agent.
nsultation for silicone defoamer in Qinghai>Bridging adsorption and flocculation. ???? Adhesiveness: It can be bonded through mechanical, physical and chemical action. ???? Resistance reduction: PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM in the water can reduce the resistance by 50-80%. ????Thickening: PAM has a thickening effect under neutral and acid conditions. When the PH value is above 10, PAM is easy to hydrolyze. When it has a semi-net structure, the thickening will be more obvious. Edit the product usage characteristics of this paragraph 1?? Edit the technical indicators of this paragraph? Technical indicators? Project? Model? Appearance. Flocculation: PAM can neutralize suspended matter through electricity.
10—35 ≤0.2 The pH value of water is neutral or alkaline cationic white particles 500-1200 ≥88 Ionity 5-80 ≤0.2 Belt type centrifugal filter press non-ionic white particles 200-1500 ≥88 Degree of hydrolysis 0-5 ≤0.2 The pH value of water is neutral or alkaline.
Used in the paper industry. Improve the retention rate of fillers, pigments, etc., and increase the strength of paper (including dry strength and wet strength). In addition, it can also improve the tear resistance and porosity of paper to improve visual and printing performance. It is also used in food and tea packaging paper.
nsultation for silicone defoamer>Its consumption accounts for 81% of total domestic consumption. Water treatment is the second largest consumption area of polyacrylamide in my country. The urban sewage treatment rate in China is less than 30%, the recycling rate of industrial water is 60%, and the industrial wastewater treatment rate is 77%, which is far behind the developed countries. Polyacrylamide is used as a flocculant in my country’s urban water treatment? And the amount of wastewater treatment in chemical, metallurgy, paper, printing and dyeing, sugar, MSG, coal, building materials and other industries will continue to increase. In super absorbent resins, cement enhancers, Adhesives, leather retanning agents and other fields.
nsultation for silicone defoamer in Qinghai>The sludge sedimentation is not good. If the bleached sludge is brown, it may be caused by the aging of the sludge. You can strengthen the sludge discharge and appropriately reduce the aeration. Of course, it is necessary to reduce the aeration on the basis of ensuring that the ammonia nitrogen reaches the standard. Primary treatment—mechanical treatment section: The mechanical (primary) treatment section includes structures such as grids, grit tanks, primary sedimentation tanks, etc., for the purpose of removing coarse particles and suspended solids. The principle of treatment is to achieve solid-liquid separation through physical methods. , Separate pollutants from sewage, which is a commonly used sewage treatment method. Mechanical (primary) treatment is all sewage treatment process engineering (although some processes sometimes omit the primary sedimentation tank), the typical removal rates of BOD5 and SS in the primary treatment of urban sewage are 25% and 50%, respectively. In biological dephosphorization and denitrification sewage treatment plants, aerated grit tanks are generally not recommended to avoid the removal of rapid degradation of organic matter; in the case of raw sewage water quality characteristics that are not conducive to dephosphorization and denitrification, whether or not the primary sedimentation is set up or not and how to set it The method needs to be carefully analyzed according to the subsequent process of water quality characteristics
