What is the cooling tower cleaning agent and the introduction of the role of cooling tower cleaning agent

　　In a closed cooling tower, the water is not exposed to the air, and the re-cooling of the water is performed by other cooling media through a certain type of heat exchange equipment. The cooling water loss is very small and basically not concentrated.wNCCooling tower noise reduction treatment manufacturer

　　In an open cooling tower, the cooling water passes through the heat exchanger and the water temperature increases to become hot water. The hot water is aerated by the cooling tower and touches the air. The water temperature drops due to the transpiration and touch heat dissipation of the water, and the cooled water is recycled. . This system is widely used in factories.wNCCooling tower noise reduction treatment manufacturer

　　Because the open cooling tower evaporates part of the water in the circulation process, it must make up for certain fresh water and discharge certain concentrated water to maintain the salt content of the circulating water or a certain ion content at a certain value. In comparison, the circulating water The fresh water to make up is very limited, generally only about one-fortieth of the direct flow and the amount of water.wNCCooling tower noise reduction treatment manufacturer

　　1. The status quo of the application of cleaning agents for industrial cooling towerswNCCooling tower noise reduction treatment manufacturer

　　Because of the different effects of various cooling tower cleaning agents, the synergy between the agents should be used and the agents should be used together. The pharmaceutical formulations used in China are mainly phosphorous, accounting for about 52%~58%, molybdenum formulations account for 20%, silicon formulations account for 5%~8%, tungsten formulations account for 5%, and other formulations account for 5%~10 %. The primary water treatment chemicals include: organic phosphates, polycarboxylic acids, sterilants, corrosion inhibitors, scale inhibitors and dispersants, as well as more than 60 chemical cleaning agents, coagulants, and defoamers. There are more than 120 major cooling tower cleaning agent manufacturers. Flocculant, water treatment agent, scale inhibitorwNCCooling tower noise reduction treatment manufacturer

　　2. Research progress on the mechanism of cooling tower cleaning agentwNCCooling tower noise reduction treatment manufacturer

　　The mechanism of action of medicaments on metals in corrosive media is relatively complicated, and it is also a research topic that people pay more attention to. The selection of many new methods and new skills provides a useful tool for the study of the mechanism of medicaments. On the basis of conventional methods, the application of many new methods has deepened the research on the mechanism of action of drugs.wNCCooling tower noise reduction treatment manufacturer

　　Potential polarization curve measurement, AC impedance measurement, steady-state polarization curve measurement, linear resistance measurement Phil linear extrapolation, small amplitude cyclic voltammetry, X-ray electron spectroscopy, Auger electron spectroscopy, laser ellipse On the basis of conventional research methods such as photometric method, new methods and new skills such as constant potential-constant current transient response measurement techniques, harmonic analysis methods, chopper methods, Mössbauer spectroscopy methods, and quantum chemistry methods have been used. Makes China's cooling tower cleaning agent theory and testing skills have achieved remarkable results. Some researches on the mechanism of action of medicaments and testing skills have reached the international advanced level. Because the research on basic theories of pharmacy in China has been continuously carried out, it has promoted the expansion and development of the types of pharmaceutical products in China.wNCCooling tower noise reduction treatment manufacturer

　　Three, pharmacy compounding skillswNCCooling tower noise reduction treatment manufacturer

　　In order to avoid problems such as scaling, corrosion and bacterial growth of industrial cooling towers, chemical agents such as corrosion inhibitors, scale inhibitors, and sterilants are usually added to the cooling water, which is commonly referred to as water stabilizer. Using the synergy between these agents can improve the effect of water quality stabilization and reduce production costs. Commonly used compound formulas are: polyphosphate + zinc salt, phosphate + polyphosphate, polyphosphate + silicate, organic phosphate + polyphosphate + zinc salt, organic phosphate + polyphosphate + benzothiazole , Silicate + organic phosphate + benzotriazole, zinc salt + organic phosphate + azole, polyphosphate + organic phosphate, zinc salt + molybdate, aromatic azole + organic phosphate + phosphate +Molybdate and so on.wNCCooling tower noise reduction treatment manufacturer

　　It is worth noting that some corrosion inhibitors are also good scale inhibitors, such as ATMP, HEDP, EDTMP, PBT-CA, etc. If these agents are used to avoid cooling tower corrosion, their application concentration is 10mg/L (preferably Used in combination with other water treatment chemicals) above, if it is used to avoid scaling, the general application concentration is 2~5mg/L.

　　Fourth, the development of new types of pharmaceuticalswNCCooling tower noise reduction treatment manufacturer

　　Our country has researched and developed a series of industrial water corrosion inhibitors, scale inhibitors and sterilant products, which have been used in large-scale steel, petroleum, fertilizer, and electric power production, and have dealt with the problems of corrosion, scaling and bacterial reproduction of industrial cooling water equipment. , Has saved a lot of costs for the country, and established and improved relevant water quality scale inhibition, sterilization specifications, specifications and monitoring skills and management systems, ensuring the safe operation of industrial production and achieving remarkable results.wNCCooling tower noise reduction treatment manufacturer

　　At present, the functions of our country's corrosion inhibitors and scale inhibitors are appropriate to those of foreign advanced products, and they have good treatment effects. With the progress of the research level in our country and the development of organic composition industry and fine chemical technology, the use of computers in molecular calculations is expected to form new organic corrosion inhibitors, scale inhibitors, and sterilant compounds with specific structures. Corrosion, scale, and sterilization functions, and has the characteristics of high efficiency, low toxicity, and low price.wNCCooling tower noise reduction treatment manufacturer
