COATING METHOD OF PORCELAIN INSULATORS METAL FITTING AND PORCELAIN INSULATOR MANUFACTURED BY THEREOF

摘要

The present invention relates to a method for coating metal fittings for preventing degradation of performance of magnetic insulators and improving light reflectance, and magnetic insulators manufactured by the method, and more particularly, to methyltriethoxysilane (CH 3 Si (OC 2 ) H 5 ) 3 ), ethanol, hydrochloric acid and water to prepare a methyl silicone solution by mixing in a certain ratio, magnesium acetate (Mg(CH 3 COO) 2 ), hydrofluoric acid (HF), anhydrous ethanol and ethanol in a certain ratio formulated by coating the gold detention surface of the magnetic insulators step, step, and the coating liquid for a mixture of the methyl silicone solution and the MgF 2 solution to prepare a coating solution for preparing a MgF 2 solution zinc (Zn) coating film is formed MgF 2 Through a coating method including a coating step of forming a coating film, a MgF 2 coating film is additionally double-coated on the zinc coating film to prevent the formation of a natural oxide film and improve light reflectance.
