COMPOUND FOR PRODUCTION OF ELECTRIC INSULATING COATING Russian patent published in 1998 - IPC

Abstract RU 2108634 C1

FIELD: treatment of steel for producing electrical insulating coatings on its surface; may be used in electrical engineering. SUBSTANCE: applied to sheet anisotropic electrical steel is compound additionally containing liquid combined fertilizers with the following amounts of components, wt.-%: orthophosphoric acid, 45.3-48.5; magnesium oxide, 3.9-4.4; aluminum hydroxide, 2.0-2.6; boric acid, 0.3-0.4; liquid combined fertilizers, 5-10; water, the balance. EFFECT: 4-6-fold acceleration of polymerization of electric insulating solution, saved energy resources due to reduced time of drying, higher magnetic properties and quality of coatings. 2 cl, 1 tbl
