Following the development trend of economic development, the application of anticorrosive spiral steel pipes has become more common, but many people know little about its characteristics, and very few know about its maintenance. So how to maintain and maintain the anticorrosive spiral steel pipe?
Many people think that the anti-corrosion spiral steel pipe is never rusty. In fact, the anti-corrosion spiral steel pipe is excellent in corrosion resistance. The reason is that a layer of purified film is formed on the surface. In nature, it exists in the shape of a more stable metal oxide. . In other words, although the anti-corrosion spiral steel pipe is not the same according to the application standard and the air oxidation level is different, it is all oxidized by the air. This situation is generally called erosion.
In order to achieve greater corrosion resistance and aesthetics, the surface of the anticorrosive spiral steel pipe must be kept clean. If the anti-corrosion spiral steel pipe number and surface smoothness are properly selected, and the cleaning plan is carried out on time, it will result in excellent characteristics and a longer service life. Be sure to avoid surface environmental pollution and the generation of residues on the surface of the anticorrosive spiral steel pipe. This kind of residue will be fine particles of iron or rust caused during the construction period of the project. Industrial production and the air standards produced by nature all cause the same corrosive residues, such as salt residues under the deep-sea standard.
Therefore, the surface of the anticorrosive spiral steel pipe must be cleaned and maintained on time to maintain its surface and increase its service life. When cleaning the surface of the anticorrosive spiral steel pipe, be sure to pay attention not to cause scratches on the surface, and prevent the application of bleach ingredients and cleaning fluids and wire brushes. For grinding special tools, etc., in order to remove the cleaning fluid, use cold water to clean the surface after cleaning.
Clean up common problems
① No abrasive liquid with particles is allowed in the cleaning liquid to avoid grinding hair lines or damaging the surface layer.
②When cleaning, follow the direction of the hairline and clean it in order.
③After washing with cleaning fluid, clean it with plenty of cold water, and finally wipe it with a damp cloth.
2. Cleaning solution composition regulations: It is recommended to purchase matching stainless steel cleaners according to the detailed situation, which are available in the Chinese sales market (the ingredients should be considered: ph: partial alkali; specific ingredients: water content:> 30%).
3. It should not contain acid-alkaline chemical substances, very acids with chlorine and chemical substances with chlorine, followed by hydrochloric acid, sulfurous acid and acids with air oxidation.
4. The cleaning agent for opening the glue for hairline anticorrosive spiral steel pipes should be non-reducing solvents, such as ethanol, xylene, and toluene.
5. For anticorrosive spiral steel pipes whose surface has been solved, the cleaning fluid should be carefully used. The cleaning fluid that is neutral and does not contain grinding fluid should be used.
