彩色涂層鋼板是家用電器產(chǎn)品廣泛使用的板材。對家電彩涂鋼板通常有強(qiáng)度、沖壓成形性、抗腐蝕性、表面質(zhì)量和裝飾性的要求。在鋼鐵產(chǎn)品中

彩涂鋼板基板屬于普通的鋼材品種,技術(shù)含量較低。通過對家電彩涂板平板,劃線,切口,折彎,沖壓等類型鹽霧試驗(yàn)的比較,研究了不同涂層,不同基板,

不同鍍鋅量等對家電彩涂鋼板耐蝕性的影響.研究結(jié)果表明:隨著鍍鋅量的增加,家電彩涂鋼板在耐涂層起泡,折彎處銹蝕,切口腐蝕蔓延等方面的耐蝕性

增加;在改進(jìn)金屬漆系列彩涂鋼板耐切口腐蝕能力方面,提高基板鍍鋅量是最有效的措施;隨著沖杯力和沖杯深度的增加,彩涂家電鋼板的切口耐蝕性降低.

Color-coated steel plate is a widely used plate in household electrical products.Home appliance painted steel plate usually have strength, stamping forming,

corrosion resistance, surface quality and decorative requirements.In the steel products, the color-coated steel plate substrate belongs to the ordinary steel

varieties, and the technical content is low.Through the comparison of the salt mist test on the plate, marking, incision, bending and stamping, the influence of

different coatings, different substrate and different galvanizing plating on the corrosion resistance of the painted steel plate is studied. The results show that

with the increase of galvanization, the corrosion resistance, corrosion and spread of incision is the most effective measure and the corrosion resistance of the

plate is reduced.
