日新制钢近日宣布开发成功不含铬的镀锌钢板。过去的镀锌钢板中一般均含有少量的3价铬,6价铬的化合物,这次作为环保型产品以适应家电厂等的绿色采购。电镀为镀层金属电镀在钢板上的方法,比将镀液镀在钢板上的热镀法镀层较薄,为此对电镀板作为防锈的后处理工序实施涂铬化合物的镀膜。日新制钢通过以钛系化合物代替了铬化合物,在保持镀板耐蚀性的同时,
Nisshin Steel recently announced the successful development of chromium-free galvanized steel. Past galvanized steel generally contain a small amount of trivalent chromium, hexavalent chromium compounds, this time as an environmentally friendly products to meet the green procurement, such as power plants. Electroplating plating metal plating on the steel plate, the plating solution is plated on the plate of the hot-plate coating thinner, for the plating plate as a rust-proof post-treatment process coated with chrome compound coating. Nisshin Steel by replacing titanium compounds with chromium compounds, while maintaining plate corrosion resistance at the same time,
