Foshan steel construction, such as factories, airports, etc., we are familiar with, but many users of steel structure construction program is not concerned about, but the steel construction program for the construction of such a great impact on quality, what steel construction program? The main content of the steel structure construction program which? Roof construction is very important to the house, the application of steel structure is also increasingly popular. However, steel surface corrosion has been the impact of steel quality, life of the main factors. Corrosion of steel structure a lot of incentives. Environment, should avoid long-term exposure to steel structures in relatively high relative humidity environment, and the environment of acid, salt and other chemicals will accelerate the corrosion of steel; followed by the design is unreasonable from the current point of view, the main impact of steel Surface corrosion of natural factors, paint the aging, the reasons for the construction and so on. These are also the main factors that cause the corrosion of steel surface.
Thus, for the Foshan steel structure, the initial construction of the steel structure for the address of climate factors, the choice of paint, as well as the degree of professionalism of the construction unit must have a certain requirement, in these relevant factors, the combination of steel structure engineering Of the overall quality assurance will have a better effect.
Specific measures are:
(A) to ensure that the effect of treatment of steel substrates meet the standard requirements (B) the use of multiple coating method to reduce the anti-rust primer pinhole defects.
(C) pay attention to the top paint, intermediate paint coating construction conditions and construction methods.
(D) to take the coating thickness detection, pin hole detection, coating adhesion detection.
Heavy-duty, long-lasting coatings consist of a primer, intermediate coat and topcoat.
From the long-term economic considerations spray coating the most economical but a one-time investment good construction of the coating can be 10 years
No maintenance is required. Epoxy zinc-rich primer + epoxy-iron intermediate paint and acrylic polyurethane long-lasting protection system has a better economy.
