电镀锌彩钢板镀层的密度比镀锌板小很多?

由于镀锌钢板涂层的密度比镀锌板小得多,在钢基体和涂层厚度相等的情况下,每吨镀锌板的面积比镀锌板大得多,这将为客户创造更多的使用价值。
镀锌钢板切口周围涂层的成分开始反应,形成以氢氧化锌和碱性氯化锌为主要成分的致密保护膜。保护膜的导电性较弱,可以抑制切口部分的腐蚀反应。涂层中所含的硅也能促进上述保护膜的形成。
使镀锌板的需求增长过快。目前,我国镀锌板的生产规模在数量、品种和质量上都不能满足国内市场的需求。
表层涂有耐候性好的彩色涂料和特殊的强化学聚酯,保证镀铝锌钢板在使用多年后仍能保持原有的色泽,底层涂有浅灰色涂料,使钢板更加美观。

镀锌钢板的主要用途:
建筑业:民用和工业建筑的屋顶、外墙、车库门、栅栏和百叶窗。
汽车工业:汽车消声器、排气管及催化转化器隔热罩、车身底部零件、路标。
这种复合材料不仅环保,而且具有较高的强度、耐腐蚀性和装饰性。与其它材料相比,使用寿命更长,大大节约了生产成本。
而且, 镀锌钢板广泛应用于钢铁、军工、家电、电子等行业。

Because the density of galvanized sheet coating is much smaller than that of galvanized sheet, under the condition that the thickness of steel substrate and coating is equal, the area per ton of galvanized sheet is much larger than that of galvanized sheet, which will create more use value for customers.

The components of the coating around the incision section begin to react, forming a dense protective film with zinc hydroxide and alkaline zinc chloride as the main components. The conductivity of the protective film is weak, which can inhibit the corrosion reaction of the incision section. The silicon contained in the coating can also promote the formation of the above protective film.
So that the demand of galvanized sheet increases too fast. At present, the production scale of galvanized sheet in our country can not meet the demand of domestic market in terms of quantity, variety and quality.
The surface layer is coated with colored coating with good weather resistance and special strong chemical polyester to ensure that the aluminum zinc plated steel plate can maintain its original color and luster after many years of use, and the bottom layer is coated with a light gray coating to make the steel plate more beautiful.
Main uses of galvanized steel sheet:
Construction industry: roofs, external walls, garage doors, fences and shutters of civil and industrial buildings.
Automobile industry: automobile muffler, exhaust pipe and catalytic converter heat shield, automobile body bottom parts, road signs.
This composite material is not only environmentally friendly, but also has higher strength, corrosion resistance and decoration. Compared with other materials, it has a longer service life and greatly saves the production cost.
Moreover, galvanized sheet is widely used in steel, military industry, home appliances, electronics and other industries.
