The necessity of spray of aluminous profile powder

Aluminous profile is machined smally, easily with its proportion, mechanical strength is great wait for a feature to apply the commodity such as wall of the door window at building thing, act extensively to go up for years. Aluminium is have silvery white burnish prep according to vivid light metal, its are able to bear or endure corrode sex has the following two features:
Purity is taller, be able to bear or endure corrode sex is better, head if be in because of aluminium,air adjacency and oxygen produce effect, produce in aluminous surface a film of very thin close and natural oxidation, what than other metal oxidation film generates is fast and many thick, then stem what harmful gas and water divide in air is farther corrode, rose to protect action.
The mechanical intensity of aluminous profile is high, but be able to bear or endure corrode sex is low. Of aluminium be able to bear or endure although corrode sex is good, but mechanical intensity is poor, this is applied in what aluminium restricted on certain level, for this, everybody participates in the other metal such as appropriate magnesium, copper, zinc in aluminium, make the aluminium alloy of all sorts of types, make aluminous mechanical intensity rises greatly, apply limits to be extended greatly, but be able to bear or endure corrode sex is poorer than aluminium, have consequently can corrode because of oxidize and sufferring. This undertakes with respect to need pulverous besmear installs pair of aluminium alloy profile to try to protect.
The aluminous profile that fits through pulverous besmear is divided have taller be able to bear or endure outside corrode sex, still have color diversity, the surface has felt character wait for a lot of good qualities, with the coordinate of photograph of paint of the wall outside building of all sorts of color, build content individual character with what bad habit differs.
