Hebei zhao Ji'an home appliance with galvanized sheet and aluminum plated galvanized sheet have what difference?
鍍鋅層與鍍鋁鋅合金相比,化學(xué)性質(zhì)相對(duì)活潑,因此防腐蝕能力差別較大。在同等室外條件下的測(cè)試表明,鍍鋁鋅板的使用年限為鍍鋅板的四倍以上。
Compared with galvanized alloy, galvanized layer is relatively active, so the corrosion prevention ability is quite different.Testing under the same outdoor conditions shows that the service life of aluminum ized galvanized plate is more than four times that of galvanized plate.
鍍鋅板與鍍鋁鋅板的區(qū)別主要在于鍍層的不同,鍍鋅板的表面均勻地分布著一層鋅材料,對(duì)母材起著陽(yáng)極保護(hù)的作用,也就是說(shuō)鋅材料的替代性腐蝕保護(hù)了母材的使用,只有當(dāng)鋅全部腐蝕完了才能傷害到里面的母材。
The difference between galvanized plate and aluminum galvanized plate mainly lies in the difference of coating layer, the surface of galvanized plate is evenly distributed with a layer of zinc material, playing a role of anode protection of the mother material, that is to say, the alternative corrosion of zinc material protects the use of the base material, only when all the zinc corrosion can harm the base material inside.
鍍鋁鋅板的表面鍍層是由55%的鋁,43.5%的鋅和少量的其它元素構(gòu)成,在微觀下鍍鋁鋅涂層表面為蜂窩結(jié)構(gòu),由鋁構(gòu)成的“蜂巢”內(nèi)包容著鋅,在這種情況下,鍍鋁鋅涂層雖然也起著陽(yáng)極保護(hù)的作用,但一方面由于鋅含量的減少一方面由于鋅材料由鋁包裹不易電解因此陽(yáng)極保護(hù)的作用大大減少,因此一旦鍍鋁鋅板被切開(kāi),在切斷的邊緣基本喪失被保護(hù)的情況下很快就會(huì)銹蝕,所以鍍鋁鋅板應(yīng)當(dāng)盡量少切割,一旦切割后應(yīng)用防銹漆或富鋅漆保護(hù)邊緣,才能夠使板材的使用壽命延長(zhǎng)。
The surface coating of galvanized sheet is made of 55% aluminum, Of 43.5% zinc and a small number of other elements, The microscopic aluminum-plated zinc coating surface is a honeycomb structure, The "hive" made of aluminum contains zinc, under these circumstances, Although the galvanized zinc coating also plays an anodic protection role, But on the one hand, due to the reduction of zinc content on the other hand, because the zinc material is not easy to electrolysis by aluminum, the effect of anode protection is greatly reduced, Thus, once the aluminum-plated galvanized plate is cut through, Soon to rust after the loss of basic protection of the cut edge, So the galvanized aluminum plate should be cut as little as possible, Once cutting, protect rust proof paint or zinc rich paint, Can make the service life of the plate is extended.

二、材質(zhì)不同
二、the material is different
鍍鋅板:是為防止鋼板表面遭受腐蝕延長(zhǎng)其使用壽命,在鋼板表面鍍上一層金屬鋅。
Galvanized sheet: it is to coat steel sheet with a layer of metal zinc to prevent corrosion of steel sheet and prolong its service life.
鍍鋁鋅鋼板:表面呈特有的光滑、平坦和華麗的星花,基色為銀白色。其表面鍍層是由55%的鋁,43.4%的鋅和1.6%硅。
Aluminium galvanized steel plate: the surface is unique smooth, flat and gorgeous star flower, the base color is silver white.Its surface coating is made of 55% aluminum, 43.4% zinc and 1.6% silicon.
