Description
щают, промывают декантацией от остатков гипса и подают на центрифугу.Slipped, washed by decantation from the remnants of gypsum and served on a centrifuge.
Влажный осадок (4,7 т) сушат, получа 1 т порошкового продукта, содержащего 0,86 т Mg(OH)2 и 0,06 т гидроокиси хрома или гидроокиси никел , или гидроокиси цинка, или гидроокиси железа, или гидроокиси алюмини .The wet cake (4.7 tons) is dried, yielding 1 ton of a powder product containing 0.86 tons of Mg (OH) 2 and 0.06 tons of chromium hydroxide or nickel hydroxide, or zinc hydroxide, or iron hydroxide, or aluminum hydroxide.
Введение добавок меньше, чем 12%, значительно снижает их диспергирующее вли йие на гидроокись магни ; а более 25% отрицательно вли ет на адгезию покрыти к металлу, что приводит (при последующих операци х) к образованию дефектов грунтового сло покрыти трансформаторной стали.The introduction of additives less than 12% significantly reduces their dispersing effect on magnesium hydroxide; and more than 25% adversely affect the adhesion of the coating to the metal, which leads (in subsequent operations) to the formation of defects in the soil layer of the coating of transformer steel.
Вли ние добавок на свойства гидроокиси магни показано в таблице.The effect of the additives on the properties of magnesium hydroxide is shown in the table.
Применение покрыти из Mg(OH)2, получаемой согласно изобретению, на 5-10% снижает удельные потери в стали и на 7- 10% повышает магнитную индукцию.The application of the Mg (OH) 2 coating obtained according to the invention reduces the specific steel loss by 5-10% and increases the magnetic induction by 7-10%.
