23-6和23-4两种带锈防锈剂是用于锈蚀钢铁表面的处理剂及防腐剂。它改变涂料施工前用机械或化学酸洗除锈的传统方法,而是直接涂在锈蚀钢铁的表面上,具有防锈底漆的作用。因此它具有“带锈涂料”的功能。但是,由于它不具备涂料要求的技术标准,故不称为“涂料”或“底漆”。 23-6 and 23-4 are both rust and rust inhibitors used as treatment agents and preservatives on rusted steel surfaces. It changes the traditional method of removing rust by mechanical or chemical pickling before the application of the paint, but instead directly coats the surface of the rusted steel and has a rust-preventing primer. So it has the function of “with rust coating”. However, because it does not have the technical standards for coating requirements, it is not called “paint” or “primer.”
