Hainan Steel News: metal steel anti-acid corrosion coatings concern

ZS acid corrosion coatings can be useful to prevent the workshop steel structure of uniform corrosion, uneven corrosion, points (pit) corrosion, stress corrosion, hydrogen embrittlement and other metal corrosion phenomenon, completely solve the stress corrosion and hydrogen embrittlement of the steel structure workshop is sudden brittle fracture without obvious signs of deformation, avoid danger, ensure the safety of industrial production, non-corrosive metal steel structure is also of concern.
Metal Steel Such as: lightning rod tower, sea lighthouse, large reservoir gates, water tower, offshore oil facilities, tankers, tank, tank, tank, carbonation tower, heat exchanger, chimney, container, ship hull, offshore platform steel structure, etc. These steel structures in steel atmospheric environment by the sun, wind, rain, snow, frost, and the role of temperature and humidity changes throughout the year, during which atmospheric oxygen and moisture is an important cause of outdoor steel structure corrosion factor, Chi Shing Wai Wah experts pointed out that anti-corrosion coatings, causing corrosion of steel industrial gas containing SO2, CO2, NO2, CI2, H2S and NH3, etc., though the content of these ingredients is small, but for steel corrosion damage are can not be ignored, during SO2 the greatest impact, CI2 metal surface passivation film can be destroyed. These gases dissolved in the water acidic, acid rain, corrosion of metal facilities.
Are long-term in the marine atmosphere, industrial atmospheric corrosion environments. To long-term use, without large-scale repairs, long-lasting protective coating is best for the former, the service life of up to 20--30 years, less repair costs and obtain significant economic benefits. Metal steel acid corrosion coatings effectively prevent acid corrosion protection steel structure long acid corrosion. Steel structure workshop mainly refers to the main load-bearing member is made of steel, including steel columns, steel beams, steel base, steel roof, steel roof and so on. Wei Sheng Zhi Hua specialized anti-corrosion coatings researchers found that long-term site tracking summary, steel corrosion refers to the workshop corrosive gases, moisture or media purely in the physical and chemical interaction between the metal and the environment, as well as iron and steel materials in the air arising from oxidative corrosion scene from oxygen and water molecules oxidation, thus weakening the capacity and service life of steel components, metal performance changes, resulting in metal, the environment and its component-based power will damage the scene, so that to produce damaging effects, good performance ZS anti-corrosion coatings anticorrosive steel structure workshop can make more than 20 years.

Corrosion of steel in the environment is inevitable, especially corrosion in aggressive media effect, the steel will corrode, aggressive media are mainly acid corrosion, alkali and salt corrosion of three types of corrosion. According to their patterns, liquid phase and gas phase corrosion corrosion two categories. In addition, rain, dust, temperature effects and exposure to atmospheric humidity and atmospheric, steel and other metals will cause corrosion of steel. Located in Fengtai District of Beijing, Dong Tieying Wei Sheng Zhi Hua Development of the information produced corrosion mechanism is different, and some acid corrosion, some weak acid corrosion, some oxygen acid corrosion, some hydrogen acid corrosion, and these acids as the temperature rises, corrosion When the degree of geometric growth strong. ZS-711 for data inorganic anti-corrosion coatings, ZS-811 high temperature anti-corrosion coatings and ZS-1033 hydrofluoric acid corrosion-resistant coatings, ZS-1034 acid anti-corrosion coatings of different projects in accordance with the national standard test, the test results above anticorrosive coating corrosion resistance acid corrosion completely meet international design standards. Acid corrosion anti-corrosion coating solution is a solution of an inorganic polymer chelating filming the new Chi Sheng Weihua special, has siloxy -Si-O-Si- bond as the basis, grafting organic alkyl side chains as his assistant, and then has a hydroxyl-terminated chain chelated anticorrosive film-forming material, ZS-711 anti-corrosion coating molecules bond to a hydroxyl group on the silicon atom connected to chelation, an alkyl group with good corrosion ternary synergistic effect, strong solution stability, reducing the interior of the polymer influence, film was more compact, strong adhesion, high temperature. ZS above acid corrosion coating can be useful to prevent uniform corrosion of the steel structure workshop, uneven corrosion, points (pit) corrosion, stress corrosion, hydrogen embrittlement and other metal corrosion phenomenon, completely solve the stress corrosion and hydrogen embrittlement of the steel structure workshop are brittle fracture occurs suddenly without obvious signs of deformation, avoid danger, ensure the safety of industrial production, non-corrosive metal steel structure is also of concern.
