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.
Prednosti upotrebe slojeva praha za čelična protivpožarna vrata su:
Glatka površina izolovanih šupljih metalnih vrata:
Osim što omogućava prijanjanje praha, ali i osigurava ravnomjernu distribuciju praha, površina vrata obične četke je glatkija.
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 adhezija:
Protupožarna vrata će biti osušena nakon prskanja prahom. Stoga se boja može čvrsto pričvrstiti na površinu vrata i neće lako pasti.
Visoka otpornost na koroziju:
Debljina površinskog premaza doseže 35 mikrona, što je 4-10 puta deblje od obične boje. Metal ispod nije lako korodirati, čime se povećava trajnost vrata.
Odlična fleksibilnost:
Za razliku od boje, krilo vrata ili okvir prekriven praškastim premazom neće popucati čak ni ako je savijen, a stopa rastezanja može doseći 100 posto -800 posto.
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.
