Metal steel structure anti-acid corrosion coatings concern

Metals such as steel structure, 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 construction, etc. These steel structure in steel structure atmosphere by the sun, wind, rain, snow, frost and temperature and humidity changes throughout the year effect, where the atmospheric oxygen and moisture is caused by corrosion of the important field of steel structure factor, pointed out, causing corrosion of the steel structure of industrial gases containing SO2, CO2, NO2, CI2, H2S and NH3, etc. These ingredients although content is small, but the steel is corrosion hazards can not be ignored, in which the greatest impact SO2, CI2 metal surface passivation film can be destroyed. These gases dissolved in the water acidic form acid rain, corrosion of metal facilities. Hainan Steel

    Are long-term in the marine atmosphere, industrial atmospheric corrosion environments. To long-term use, without large-scale maintenance, long-lasting protective coating is best for the former, the service life of up to 20--30 years, less maintenance costs, availability of obvious 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 composed of steel, including steel columns, beams, steel structure foundation, steel roof, steel roof and so on. Wei Sheng Zhi Hua specialized anti-corrosion coatings researchers found that long-term site-tailed summary, steel construction Corrosion is 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 oxidation corrosion phenomena arising from oxygen and water molecules from oxidation, thus weakening the capacity and lifetime member of the steel structure, the metal performance change, resulting in metal, environment and power lines will constitute the phenomenon of damage, so that to the production of harmful effects, good performance ZS anti-corrosion coating allows the steel structure workshop corrosion than 20 years.

    Steel structure corrosion 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.

    Material 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 increases, the degree of corrosion geometry when growth becomes strong. Inorganic materials ZS-711 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 carried out in accordance with the national standard test, the test results above anticorrosive coating corrosion resistance acid corrosion fully meet international design standards. Acid etching is a new anti-corrosion coating solution Hua Wei Sheng Zhi special inorganic polymer membrane solution chelate composition has silicon group -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 coatings can effectively prevent uniform corrosion steel structure workshop, uneven corrosion, points (pit) corrosion, stress corrosion, hydrogen embrittlement and other metal corrosion, steel structure completely solve the workshop stress corrosion and hydrogen embrittlement 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.
