For related corrosion, the following anti-corrosion methods: here introduces corrosion, electrochemical protection. ① inhibitor chromate corrosion inhibitor as a main component is commonly used in cooling water system, a chromium ion is an anode (process) inhibitors, when used with a suitable cathode inhibitor composition, it is able to obtain satisfactory and economical anti-corrosion effect. Chromate - zinc - polyphosphates: polyphosphates is used because it has the effect of cleaning metal surfaces, there is the Corrosion, polyphosphates may be partially converted to orthophosphates, they can also generate large with calcium colloidal cations inhibit cathodic process. Chromate - zinc - phosphonate: This method is similar to the use in place of sodium polyphosphates outer phosphonate with one method, amino-methylene phosphates can also be used for the pH ratio of the polyphosphate to be specified high places. Amino methylene phosphonates can prevent scale, even if the pH value of 9 is also able to control the precipitation of calcium salts. Chromate - zinc - hydrolyzed polyacrylamide: Because cationic copolymer dispersion hydrolyzed polyacrylamide, capable of preventing or inhibiting scale to the production of dirt. ② electrochemical protection and cathodic protection anode protection. Cathodic protection is the use of an external DC power supply, the metal surface becomes cathodic protection to achieve, this method power consumption, and high costs. Anodic protection is to protect the heat exchanger connected to outside power plus anode passivation film formed on the surface of the metal, and thus protected. Siping City-energy HVAC Equipment Manufacturing Co., Ltd. is mainly engaged in the transportation of plate heat exchanger; heat exchanger unit; volume heat exchanger; spiral plate heat exchanger, the company set research, development, manufacture, integration services for; radiator information tech enterprises. Company management system, strong technical force, processing equipment, product performance of the domestic advanced level, product quality living in the same industry-leading position. Products sold throughout the country, high-quality products, improve the efficient after-sales service, and establish a good corporate image, so that we win user acceptance and praise. Not only the best companies to better concept, wholeheartedly committed to all aspects have received a steady development. In the "quality first, reasonable price, prompt delivery, integrity and thoughtful" business purpose, dedication and cooperation between the new and old customers, I hope to learn from a total of total of deliberation, Qi development!
