家电行业是钢材的一个重要下游用钢行业之一,一些能够满足家电材料需求性能、材质的钢材,统称为家电用钢。但随着原材料价格不断飙升,给家电企业带来了不小的压力,新材料替代不仅是企业当务之急,也成为了家电行业发展的新趋势。家电行业应用的主要钢材品种是冷轧板、镀锌板和电工钢板,分别占总用钢比总的29%29%25%,这三者合计占了80%以上的比重。

Home appliance industry is one of the important downstream steel industries of steel. Some steel products that can meet the needs of the performance and materials of home appliance materials are collectively referred to as steel for home appliances.However, with the soaring price of raw materials, it has brought considerable pressure to home appliance enterprises. The replacement of new materials is not only an urgent priority for enterprises, but also a new trend of the development of home appliance industry.The main steel varieties used in the home appliance industry are cold-rolled sheet, galvanized sheet and electrical steel sheet, accounting for 29%, 29% and 25% of the total steel ratio, respectively, which together account for more than 80%.

由于家电产品的百花齐放,家电板所使用的表面处理方法品种繁多,对性能的要求也各不相同,其中用得最多的是耐指纹处理。

Because of the hundred flowers of home appliance products, the use of surface treatment methods, the variety of performance requirements are also different, among which the most used is fingerprint processing.

耐指纹处理是在镀锌板表面涂覆一层极薄、透明的有机树脂薄膜,可以防止镀锌板在生产加工过程中操作人员的指纹粘附在产品上,影响产品的外观。同时,也能提高产品的耐腐蚀性能,改善成形加工时的润滑性,并作为后续涂装的粘附底层。耐指纹处理涂层最好是在钝化以后再进行,以与钝化膜共同作用,使产品既具有良好的外观,又有较好的耐腐蚀性能。

Fingerprint treatment is coated with a very thin, transparent organic resin film, which prevents the fingerprints of the galvanized plate from adhering to the product and affecting the appearance of the product.At the same time, it can also improve the corrosion resistance of the product, improve the lubrication when forming and processing, and serve as the adhesion layer of the subsequent coating.Fingerprint resistant coating is preferably conducted after passivation to work together with the passivation film, so that the product has both a good appearance and good corrosion resistance.

耐指纹涂层都是采用辊涂法涂敷于镀锌板表面。涂料中的有机树脂是以微小的颗粒悬浮于水相中,当烘干时,水分逐渐蒸发,体积随之缩小,这些分散的聚合物颗粒逐渐相互接近,颗粒之间存在的毛细管压力迫使颗粒挤紧,随着水分的蒸发进行,压力继续增加,使颗粒变形,最后颗粒间相互融合成连续的有机膜。

The fingerprint resistant coating is applied to the surface of galvanized plate.The organic resin in the coating is tiny particles suspended in the water phase, when drying, water evaporation, volume, these scattered polymer particles gradually close to each other, the capillary pressure between the particles forced particles squeeze, with the evaporation of water, pressure continues to increase, make the particle deformation, finally the particles fusion into a continuous organic film.
