B205型除锈磷化处理剂是一种新颖的刷涂型酸洗、磷化处理剂,它由高浓度的磷酸和适量的有机酸、磷酸二氢盐、高效缓蚀剂、成膜剂、表面活性剂和防流挂剂等组成。由于刷涂型处理剂的溶液和金属反应时间较短,所以它的酸度要比槽浸型高。为了使其在高酸度下除锈后能立即成膜,我们合成了具有国际先进水平的新型缓蚀剂——N烷基,β-亚氨基双丙酸钠,在完成槽浸式酸洗磷化一步法的基础上,经过无数次的试验,终于研制成功这种新颖的刷涂型酸洗磷化处理剂。在酸洗过程中,钢铁表面的锈蚀和氧化皮的除去,主要是借助该处理剂中所含的高浓度游离磷酸的化学溶解作用。同时,钢材因受所含有机酸的络合作用和 B205-type derusting phosphating agent is a novel brush-type pickling, phosphating agent, which consists of high concentrations of phosphoric acid and the right amount of organic acids, dihydrogen phosphate, high-performance corrosion inhibitor, film-forming agent, Surfactants and anti-sagging agent and other components. Due to the brush-type treatment solution and the metal reaction time is shorter, so it is more acid than the tank immersion type. In order to make it in a high acidity rust immediately after the film, we have the international advanced level of new corrosion inhibitor - N alkyl, β-iminodipropionate, in the completion of tank-dip pickling phosphorus On the basis of one-step, after numerous tests, and finally successfully developed this new brush-type pickling phosphate treatment agent. During the pickling process, the corrosion of the steel surface and the removal of scale are mainly due to the chemical dissolution of the high concentration of free phosphoric acid contained in the treatment agent. At the same time, due to the complexation of organic acids and steel
