Derusting and painting of steel structure is a steel structure contractor easier to ignore work, is also a weak link of steel structure engineering construction. This phenomenon is not correct, the great influence on the quality of construction steel structure and the coating quality of rust removal and qualified or not directly affect maintenance cost during steel structure used in the future, also affect the service life of steel structure engineering, structural safety and the fire-resistant time when the fire (fire retardant coating).
Thought this phenomenon is rooted in contracting units concerned personnel lack of understanding of the importance of painting work, coupled with a lack of quality responsibility, and even cynical, eventually lead to coating engineering quality problems often. So the supervision engineer must for attaches great importance to the derusting and painting work, strict inspection acceptance of each working procedure, and the basis of this is to ensure that the steel structure coating quality guarantee.
About the coating quality of steel structure engineering, should pay special attention to the following work:
(l) quality of rust removal of steel members in accordance with the design requirements of strict acceptance level;
(2) check the coating raw materials of the factory quality certificate, also check the fire department approval of fire retardant coating;
(3) before painting thoroughly remove dirt, oil and other debris on the surface of the component;
(4) coating construction shall be carried out in a clean, dry environment, temperature, humidity and conform to the requirements of the specification;
(5) besmear brushs times and coating thickness should comply with the design requirements;
(6) on the coating damage to do meticulous processing, coating quality assurance here;
(7) check the coating adhesion;
(8) strict inspection acceptance of appearance, ensure the quality of coating specification and standard requirements.
