PE wood grain transfer printing membrane vacuum most of the current wood grain transfer printing is PE TT wood grain film transfer to aluminum by automatic packing machine into tubular bags. From the ends of the tubular PE transfer film for bag vacuum until PE transfer film were able to sufficiently close to the aluminum. Vacuum negative-pressure based on transfer of aluminum shape and PE transfer film can withstand the negative pressure adjust, usually in the 0.3~ 0.6Mpa. Will have good vacuum aluminum to oven curing, curing temperature of and the length of time according to transfer aluminum shapes, to transfer the grain texture depth adjust factors, usually transfer temperature 180 ℃, time was 10-15 minutes. Launch has been transferred from the oven aluminum, automatic blowing PE transfer film for bagging blow, after cooling, remove residual PE transfer film.
The imitation wood grain treatment on the surface of aluminum alloy used in construction is developed with the requirement of colorful architectural decoration. It gives the surface of aluminum alloy a wood feeling through mechanical or chemical methods, so that aluminum alloy has both the characteristics of metal and the appearance of wood. At present, our COUNTRY city and countryside widely USES aluminum alloy to decorate the buildings indoors and OUTDOORS, the appearance MAINLY IS white, tawnish AND BLACK, AND wooden STRUCTURE doors AND Windows, FURNITURE and so ON are EXTREMELY unlined. Through treatment, the formation of wood grain rings on the surface of the aluminum, and then coloring, so that the plane color is light, the linear groove color is dark, light and dark, with a consistent appearance with the wood.
The wood grain processing methods on the surface of aluminum alloy used in construction include mechanical method, printing method, film pressing method and electrolysis method. The mechanical method, printing method and film pressing method can be referred to as physical method, and the electrolysis method is electrochemical method.
