Common factors affecting the anti-corrosion effect. Recently, there have been many cases where anti-corrosion coatings failed to meet the required standards; the analysis shows that problems exist in design and construction management. The key factors affecting the corrosion protection efficiency of anti-corrosion coatings include, in addition to the quality and type of the coating itself, the quality of surface preparation of the substrate, the application techniques, the thickness of the coating, as well as the use and maintenance of the equipment. To achieve good corrosion protection, all relevant factors must be taken into account; if any of these factors fail to meet the required standards or are not properly controlled, it can lead to defects in the coating, resulting in failed corrosion protection and causing economic losses and waste. Only by designing a scientific and reasonable anti-corrosion plan based on the environmental conditions of the equipment to be protected, selecting high-quality anti-corrosion coatings, ensuring the quality of installation, and carrying out proper maintenance during subsequent use, can the desired anti-corrosion effects be achieved.
The main factors for corrosion prevention are as follows: 1. Selection of materials versus the fluid (it is necessary to know the operating temperature and concentration of the fluid). 2. When using anti-corrosion coatings for protection, attention should be paid to the roughness of the metal surface as well as the application methods (such as cleaning, exposure to atmospheric moisture, etc.). 3. Selection of coatings (each type of metal has certain coatings that are suitable or not suitable for it, and there are also differences between coatings with insulation properties and those without them). This is what is meant by “large plates”
It’s especially important to choose materials under relatively harsh conditions!
