河北兆建家电用镀锌板与镀铝锌板有什么区

Hebei zhao Ji'an home appliance with galvanized sheet and aluminum plated galvanized sheet have what difference?

镀锌层与镀铝锌合金相比,化学性质相对活泼,因此防腐蚀能力差别较大。在同等室外条件下的测试表明,镀铝锌板的使用年限为镀锌板的四倍以上。

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.

镀锌板与镀铝锌板的区别主要在于镀层的不同,镀锌板的表面均匀地分布着一层锌材料,对母材起着阳极保护的作用,也就是说锌材料的替代性腐蚀保护了母材的使用,只有当锌全部腐蚀完了才能伤害到里面的母材。

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.

镀铝锌板的表面镀层是由55%的铝,43.5%的锌和少量的其它元素构成,在微观下镀铝锌涂层表面为蜂窝结构,由铝构成的“蜂巢”内包容着锌,在这种情况下,镀铝锌涂层虽然也起着阳极保护的作用,但一方面由于锌含量的减少一方面由于锌材料由铝包裹不易电解因此阳极保护的作用大大减少,因此一旦镀铝锌板被切开,在切断的边缘基本丧失被保护的情况下很快就会锈蚀,所以镀铝锌板应当尽量少切割,一旦切割后应用防锈漆或富锌漆保护边缘,才能够使板材的使用寿命延长。

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.

Aluminium-plated zinc plate, mainly used in: automobile, home appliances

二、材质不同

二、the material is different

镀锌板:是为防止钢板表面遭受腐蚀延长其使用寿命,在钢板表面镀上一层金属锌。 

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.

镀铝锌钢板:表面呈特有的光滑、平坦和华丽的星花,基色为银白色。其表面镀层是由55%的铝,43.4%的锌和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.
