不锈钢表面处理技术在家电行业中的应用

Stainless steel has excellent durability, strength and workability, etc., in the automotive, home appliances, kitchen machinery and building materials were widely used by other departments. With the expansion of its use, but also on the stainless steel surface of the coating and electroplating the surface treatment, developed with ornamental, functional surface treatment of stainless steel. One of the appliances in use, has an excellent view of a transparent coating of stainless steel and has an excellent processability of the solid lubricant coating has already begun the use of stainless steel. In this paper, special appliances sector in recent years in expanding the use of a transparent coating of stainless steel and stainless steel to introduce lubricant coating. Transparent coating of stainless steel With the expansion of the use of stainless steel, in the appliance uses, fingerprint pollution and food, medicine and other corrosion problem has been that can not be ignored, which required the implementation of resin coating. However, in the past, shading coating will lose the unique stainless steel metallic luster and ornamental. Therefore, in recent years in the prevention of pollution and corrosion of fingerprints at the same time, has also developed an excellent ornamental transparent coating of stainless steel to make it in the refrigerator, tableware cleaning drier, IH rice cookers and induction cookers and other appliances outside the decorative aspects are widely使用. The past, stainless steel outboard motor as a material, in order to give people "no rust, cleaning, hygiene," "advanced," such a good impression, but on the other hand, accompanied by "cold, dark" and other negative perceptions, which are difficult to use in the family an important reason for popularity. In this regard, a transparent coating on the surface of stainless steel design of the coating layer, a very beautiful watch, and improve the design of the home appliance products, and texture of. Especially in recent years, the emergence of color transparency film, and let people get a sense of advanced also by the soft watch, resulting in rapidly growing popularity. Below the transparent coating of stainless steel types, characteristics and uses are described. Table 1 express transparent coating types and coating characteristics. Application in home appliances, the transparent coating on stainless steel requirements have ornamental features, fingerprint resistance, and molding processing, and pollution-resistant and wear-resistant and so on. In the choice of the type used in stainless steel at the same time, we should also select a variety of coatings resins. Table 2 that the use of a transparent coating of stainless steel appliances and transparent use of the types of coatings. Can be seen that for a transparent coating of stainless steel are generally SUS304 and SUS430, the surface processing is mainly HL and NO.4 abrasive processing. However, in DVD box purposes, because of the appearance of high gloss also has the use of BA processing situation. Transparent resin paint coating with ordinary steel-based pre-coated steel plate, like most of the cases the use of excellent processability and good uniformity of the Department of polyester polymer coatings, but in IH rice cookers and washing utensils dry machine uses, the requirements of pollution-resistant, and resistant lotion, non-adhesive (adhesive when the easy oil scrubbing), it is sometimes also used acrylic paint grade silicon. In addition, a dedicated refrigerator uses, because of the frequent use of detergents for cleaning operation, so the use of detergent-resistant and excellent wear resistance, durability of the fluorine coating line.

In order to avoid damage to ornamental, mostly affixed to a protective layer after processing. Are in the processing industry must work hand-stripped to remove the protective film. Strict processing conditions, the protective film rupture will occur, causing some defects, because of protective film such as Java and a lot of questions硬伤happen. In addition, the use of protective film End of the abandoned deal with problems. From the environmental point of view, has not been applied. In order to replace the protective film, and developed a stainless steel coating subjected to lubrication and the use of household electrical appliances. Lubricant coating line in latex resin coating to add a wax component and thus have high lubricity, and stamping无垢compared to oil coating material has an excellent deep-stamping process, therefore, according to press the oil can be omitted to improve stamping operational environment. This lubricating coating used in the manufacture of stainless steel, such as deep-drawing process of the products have strict requirements. For example, in home appliances, the laundry washing machine drum parts and tableware washing dryers washing me, families with pumps and other pressure vessels. Concluding remarks It can be expected, with the rapid development of society in future demand for raw materials will be increasingly diversified, and look forward to further development of durability, high-functional ornamental surface treatment of stainless steel in order to open up new markets.
