With the continuous development of the society, some high-rise buildings made of steel structure appear more and more now. It can reinforce high-rise buildings. After long-term use, there will be long spots in some places. How should we remove them.
The mechanical or chemical method is the most important way to remove the spot of the steel structure. The quality of the surface of the steel structure depends on the effect of the spot removal to a great extent. The annealing and spot removing equipment works alone, that is, the spot removing method of high pressure water and iron sand is adopted. Its principle is to use 10MPa high-pressure water. With the progress of skills, now it has organically linked the two into annealing + speckle removal unit.
In the case of more acetic acid, austenitic steel structure containing molybdenum or molybdenum or copper should be selected. The spot removal of pure acetic acid is weak, and partial corrosion usually does not occur. However, in practice, due to the presence of impurities such as chloride ion and formic acid, it can be very sensitive to pitting corrosion and accelerate corrosion. With the progress of acetic acid temperature and concentration, it will intensify corrosion. When using the corrosion material data obtained from the laboratory, it is necessary to combine the application of practical media.
In the use of steel structures, regular cleaning and maintenance should be carried out. Do not wait for long spots to find a way to solve them, to prevent the appearance of long spots, and to improve its service life and enhance its stability.
