用于形成绝缘涂层的溶液及晶粒取向电工钢片
Abstract:
一种用于形成晶粒取向电工钢片的绝缘涂层的溶液，包括通过将磷酸盐溶液和胶体二氧化硅混合制备而成的水溶液。该水溶液中不添加铬。所述胶体二氧化硅包括经铝酸盐表面改性的二氧化硅颗粒，或者其是通过向诸如常规胶体二氧化硅之类的胶体二氧化硅中加入铝酸盐制备而成的。
Abstract(English):

A solution for forming an insulation coating of grain-oriented electrical steel sheet includes an aqueous solution prepared by mixing a phosphate solution and colloidal silica. Chromium is not added to the aqueous solution. The colloidal silica includes silica particles surface-modified by an aluminate or is prepared by adding an aluminate to colloidal silica such as conventional colloidal silica.
