How it works: there is a circulating cooling water system fouling, corrosion, biofouling and bio-sludge buildup. Continuous circulation of cooling water used in a loop, because of rising water temperatures, changes in flow velocity, evaporation of water, a variety of inorganic ions and organic enrichment, cooling towers and cold plunge pool outdoors exposed to sunlight, wind and rain, in debris to enter, as well as the structure of the combined effects of equipment and materials, and other factors, will have a serious attachment deposits, equipment corrosion and microbial infested and the resulting biological slime and other issues. Flow resistance increased heat exchange equipment, water pumps, power consumption increases, reduce the heat transfer efficiency, so that the production process conditions in an abnormal state. Therefore, the process requires the use of cooling water for the integrated treatment of these issues in order to achieve safe operation of the cooling system properly. Chemical treatment of the water circulation system is adding to the system corrosion, scale, killing other agents. Under this situation, Hangzhou Environmental Protection Equipment Co., frost edge SG-JY-type dosing device and pick EDS biocides and corrosion DH-7701 resist corrosion. Central air-conditioning systems and other circulating cooling water system for chemical processing to achieve high water safe operation of equipment. Dosing Illustration: Pharmacy divided into DH-7701 corrosion inhibitors, EGD killing inhibitor DH-7701 DH-7701 Corrosion Inhibitor Corrosion group detergents, Hangzhou dynamic chemical engineering company built the original product DH -77 on the basis of the performance characteristics and further developed. Drug molecules characteristic group maximize water dispersion, chelation, and so distort the lattice, and thus scale, corrosion performance has greatly improved. Since the introduction of the group of molecules can enhance the power-driven characteristic group in the molecule drug, thereby enhancing agents temperature capabilities. DH-7701 by the Nanjing University of Technology and Engineering Center and on-site assessment of water treatment chemicals Electric Power Research Institute of Zhejiang Province, test evaluation, and its performance is superior to similar products at home and abroad. This research company, has been part of the province of Zhejiang and power plants, petrochemical enterprises attach evaluation and praise. DH-7701 corrosion inhibitors and their esters copolymer / organic phosphine / corrosion inhibitor compound pharmacy, in the circulating cooling water system can effectively prevent the formation of various scale and the like, to prevent the formation of calcium phosphate have effects; good inhibition effect at higher temperatures combined alkaline conditions. Specifically detected by the State Department to monitor the use of proven combination of many users, the scale effect of up to 98%. As the product contains sufficient buffer multifunction device from erosion, in scale and, in a lot of cases of water-saving, but may reach equipment corrosion. EGD EGD killing corrosion inhibitor killing is the main component of a variety of natural fatty acids as raw material, through distillation and modification process, the formation of diverse organic amines. Alcohol functional group, and then the excellent performance of a variety of additives compound formed. EGD biocidal metal cation organic corrosion inhibitor amine type surfactant, having a di-long-chain group-containing cationic surfactant bilayer membrane may be formed, in order to protect the layer system. Killing mechanism: EGD killing inhibitor killing more unique mechanism, it is not using the general principles of poison, but in the water use characteristics of its cation and anion state of the cells was usually tightly adsorbed to establish seal stand on the surface closed excellent organic bilayer membrane, due to its Swiss plus a long-chain molecules with strong hydrophobic, micro-organisms and aquatic organisms are therefore oxygen barrier suffocation perish without causing organisms develop resistance. Inhibition mechanism for the metal in the water, EGD killing inhibitors alter its surface corrosion potential and effective protective layer of organic molecules to form a film on the surface, which significantly slowed the rate of corrosion of metal objects in water. The greater the concentration of inhibitor and killing its corrosion better. The test, in full compliance "GB50050-95" industrial cooling water requirements of design and technical specifications.
