家电用彩色钢板简称家电彩板,是一种用途广泛的金属材料,一直以来是家电外观件的首材料,白色家电方面主要集中在冰箱、洗衣机、干衣机、空调等产品,例如冰箱的面板、侧板,滚筒洗衣机的侧板、面板,波轮洗衣机的侧板,空调侧板等诸多方面。黑色家电方面主要是液晶电视机的后背板。在小家电方面已经广泛应用于饮水机、热水器、厨电和小家电等产品的外壳,以及黑色家电外壳。

Color steel plate for household appliances, abbreviated as color plate for household appliances, is a widely used metal material and has always been the first material for the appearance of household appliances. White appliances are mainly concentrated in refrigerators, washing machines, clothes dryers, air conditioners and other products, such as the panel and side plate of refrigerators, the side plate and panel of drum washing machines, the side plate of wave wheel washing machines, the side plate of air conditioners and many other aspects. Black home appliances are mainly the back plate of LCD TV. In terms of small household appliances, it has been widely used in the shell of water dispensers, water heaters, kitchen appliances and small household appliances, as well as the shell of black household appliances.

表面钝化处理的家电板一般为功能件,用于内板和结构件,喷涂或彩涂处理的家电板用于家电外板。一般来说,功能件对板形的要求低于家电外板对板形的要求,一般经过冲压成形处理,轻微的板形不良经冲压后可以消除,大变形量的冲压甚至能够消除明显可见的板形问题。例如,1.5mm及以上厚规格带钢一般存在卷心带头印缺陷,经过大压下量变形后,带头印缺陷可得到消除。钝化处理的家电板用做非可视件,对表面质量要求相对较低,允许存在轻微手感的锌/灰、锌渣、硌痕、夹杂物以及目视可见的色差等缺陷;喷涂或彩涂处理的家电板一般用于可见的外覆盖件,对表面质量要求较高,但由于两者表面涂层厚度不同,故对表面缺陷的要求不同。其中,喷涂处理的家电板表面涂层厚度为60—80μm彩涂板表面涂层厚度为18—28μm。喷涂表面由于涂层厚,对缺陷有部分掩盖功能,而彩涂板表面涂层薄,对表面缺陷有放大作用,所以彩涂板对表面缺陷要求较喷涂板高。

Household appliance boards with passivation treatment are generally functional parts, which are used for inner plates and structural parts, and household appliance boards with spraying or color coating treatment are used for outer plates of household appliances. Generally speaking, the shape requirements of functional parts are lower than those of the outer plate of household appliances. Generally, after stamping, slight bad shape can be eliminated after stamping, and stamping with large deformation can even eliminate obvious and visible shape problems. For example, the strip steel with thickness of 1.5mm and above generally has the defect of winding head print. After large reduction deformation, the defect of head print can be eliminated. Passivated household electrical appliance boards are also used as non visual parts, with relatively low requirements for surface quality, and slight hand feel defects such as zinc / ash, zinc slag, scratch marks, inclusions and visual color difference are allowed; Household electrical appliance boards treated by spraying or color coating are generally used for visible outer covering parts, and have high requirements for surface quality. However, due to the different surface coating thickness, they have different requirements for surface defects. Among them, the coating thickness on the surface of household appliance board treated by spraying is 60-80 μ m. The surface coating thickness of color coated plate is 18-28 μ m。 Due to the thick coating on the sprayed surface, it can partially cover up the defects, while the thin coating on the surface of the color coated plate can amplify the surface defects, so the requirements for surface defects of the color coated plate are higher than those of the sprayed plate.

家电外板在板形方面的要求非常苛刻,部分家电外板甚至比汽车板的要求还高。因为家电外板在一般情况下是经过简单弯折成型之后直接使用的,使用面绝大多数是平面,所以家电外板的板形不良将直接影响家电产品的外形和平面的反光。以冰箱侧板为例,很多冰箱侧板为U形,即冰箱侧板和冰箱顶板连为一体,钢板长度超过3m,且冰箱侧板厚度一般为0.40—0.45mm,钢板既长又薄,对板形要求苛刻。

The shape requirements of home appliance outer plate are very strict, and the requirements of some home appliance outer plates are even higher than those of automobile plates. Because the outer plate of household appliances is directly used after simple bending and forming, and most of the use surface is flat, the poor shape of the outer plate of household appliances will directly affect the shape and flat reflection of household appliances. Taking the refrigerator side plate as an example, many refrigerator side plates are U-shaped, that is, the refrigerator side plate and the refrigerator top plate are connected as a whole. The length of the steel plate is more than 3m, and the thickness of the refrigerator side plate is generally 0.40-0.45mm. The steel plate is long and thin, which has strict requirements on the shape of the plate.
