Development of Fingerprint Resistant Hot Dip Galvanized Steel Sheet for High-end Household Appliances
-
摘要: 通过合理设计光整、辊涂、烘干工艺，将钝化液成膜机理和钢板自身特性完美结合，开发出满足耐蚀性、耐高温黄变性、耐脱脂磷化性、耐碱脱脂性、耐溶剂性、耐指纹性、涂装性能、皮膜附着力优良的高端家电用热镀锌耐指纹钢板；通过试验设计，建立了基板粗糙度、膜厚、耐蚀性的对应关系，使耐腐蚀性、导电性和耐高温黄变性三项指标都能满足技术要求，产品广泛用于制作电脑机箱、服务器、影视音响、自动办公系统等高端家电外板件，目前已具备稳定批量供货能力。Abstract: By adopting suitablefinishing,roller coating and drying process,and combining the film-forming mechanism of passivation solution and feature of steel plate,we developed galvanized fingerprint resistant steel sheet for high-end home appliances which meet the corrosion resistance,high temperature resistant yellow degeneration,skim phosphating resistance,alkali degreasing,solvent resistance,fingerprint resistance,good adhesion of coating performance and the membrane of.By experiment design,the relationship amont substrate roughness,film thickness and corrosion resistance has been established.As a result,these three indicators of corrosion resistance,electrical conductivity and high temperature resistant yellow degeneration can meet the technical requirements.And the developed sheet are widely used in the production of computer chassis,server,film and television sound,plating of high-end home appliance parts for automatic office system.
