Coating process: precautions and process for steel structure derusting and coating engineering

Core tip: the rust removal and coating of steel structure is a work that is easy to be ignored by the steel structure contractor, and it is also a weak link in the construction of steel structure engineering If this phenomenon is not corrected, it will have a great impact on the construction quality of the steel structure, because the quality of derusting and coating will directly affect the maintenance cost of the steel structure in the future use period, as well as the service life of the steel structure engineering, structural safety and the fire resistance time (fireproof coating) in case of fire The ideological root of this phenomenon lies in the lack of awareness of the importance of the coating work of the relevant personnel of the contractor, coupled with the lack of quality responsibility, and even profit-making Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: steel structure derusting and painting is a relatively easy work to be ignored by steel structure contractors, and also a weak link in steel structure engineering construction If this phenomenon is not corrected, it will have a great impact on the construction quality of the steel structure, because the quality of derusting and coating will directly affect the maintenance cost of the steel structure in the future use period, as well as the service life of the steel structure engineering, structural safety and the fire resistance time (fireproof coating) in case of fire The ideological root of this phenomenon lies in the lack of awareness of the importance of the coating work of the relevant personnel of the contractor, coupled with the lack of quality responsibility, or even profit-making, which eventually leads to frequent problems in the quality of the coating project Therefore, the supervision engineer must attach great importance to the derusting and coating work, and carry out strict inspection and acceptance for each process, which is the basis and guarantee for ensuring the coating quality of steel structure As for the coating quality of steel structure engineering, the following work shall be done: (1) the derusting quality of steel members shall be strictly accepted according to the grade required by the design; (2) the factory quality certificate of coating raw materials and the approval certificate of fire protection department shall be inspected; (3) the dirt, oil stain and other sundries on the surface of components shall be completely removed before coating; (4) The coating construction shall be carried out in a dust-free and dry environment, and the temperature and humidity shall meet the specification requirements; (5) the number of times of coating and the thickness of coating shall meet the design requirements; (6) the damaged part of coating shall be treated carefully to ensure the coating quality; (7) the adhesion of coating shall be checked carefully; (8) Conduct appearance inspection and acceptance strictly to ensure the coating quality meets the requirements of specifications and standards Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
