As we all know, insulated hollow metal doors are made of galvanized steel. Although Asico use high-quality material, the appearance of the surface is still unable to reach the standard of direct use. Therefore, we need a layer of paint on the surface of the hollow metal door to make the surface flatter and more in line with the style of the project.
By now you may have heard of the cutting edge technology known as "powder coating." It's a new way of applying color that's vastly superior to good old-fashioned painting. Powder coating is applied using a dry powder that is electrostacically charged to stick to the steel doors, and then cured in an oven, to give a smooth, hard finish that is much tougher than conventional paint.
Avantajele utilizării straturilor de pulbere pentru ușile de incendiu din oțel sunt:
Suprafața netedă a ușilor metalice goale izolate:
În plus față de a face pulberea să adere, dar și pentru a asigura o distribuție uniformă a pulberii, suprafața ușii obișnuite cu pensula este mai netedă.
Perfect Durability:
Fire doors are scratch-resistant and thus more durable. Powder coated doors do not rust and have been tested for more than 4,000 hours of salt spray exposure. However, a normal painted fire door. Over time, the paint will crack, the surface will rust, and the door will be extensively damaged. It is difficult to repair manually. If the surface of the hollow metal door is scratched due to an accident, you only need to buy a small bottle of paint to restore the door to its original shape.
Super aderenta:
Ușa de incendiu va fi vindecată după pulverizarea cu pulbere. Prin urmare, vopseaua poate fi fixată ferm pe suprafața ușii și nu va cădea ușor.
Rezistență ridicată la coroziune:
Grosimea acoperirii suprafeței ajunge la 35 de microni, care este de 4-10 ori mai groasă decât vopseaua obișnuită. Metalul de dedesubt nu se corodează ușor, crescând astfel durabilitatea ușii.
Flexibilitate excelentă:
Spre deosebire de vopsea, foaia ușii sau tocul acoperit cu un strat de pulbere nu se va crăpa chiar dacă este îndoit, iar rata de întindere poate ajunge la 100% -800%.
Our powder coating is uniformly sprayed in accordance with the RAL color code. For example, insulated hollow metal doors used in hospitals will use white. The school's art room uses bright green, yellow, blue. The factory's escape route fire door is in a conspicuous red.
