ＮＫＫ近日开发成功不易生锈的耐候钢。它通过生产时在钢材表面涂上涂料 ,以保护钢材表面锈层不再发展而有利于提高使用寿命。三菱重工已在宫城县的一个桥梁工程中使用此项技术。这种防止锈层脱落向纵深发展的涂料名为“卡布丁膜 Ｍ” ,在轧后的自动生产线上涂布 ,便可使钢材在 NKK recently developed successful weather-resistant steel rust. It is through the production of steel coating in the surface to protect the steel surface rust layer is no longer conducive to improving the service life. Mitsubishi Heavy Industries has used this technology in a bridge project in Miyagi Prefecture. This to prevent the rust layer off to the depth of development of the paint called “Kapton film M”, automatic production line after rolling coating, can make steel in
