Description
(54) ЗАЩИТНАЯ ОБМАЗКА(54) PROTECTIVE LINING
( Защитную 9бмйэку го-гьь т те рецептам , указанным в таблице.(The defensive 9bmcrrrrrrrrrr recipes are listed in the table.
Дп получени обмазки готов т одно- родную смесь окиси алюмини и хромитйлюМината , затем при посто нном перемешивании постепенно добавл ют алкллохромфосфа-гаую св зку. Приготовленную смазку нанос т равномернь1М споем на чехол термопары. Чехлы, покрытые этой обмазкой, выдерживают на воздухе в течение 10-12 ч, затем провод т термообработку при 800-1000 С.A homogeneous mixture of alumina and chromium iminate is prepared for the preparation of the coating, and then with constant stirring an alklochromophosphate bond is gradually added. The prepared lubricant is applied evenly and we sing on the thermocouple cover. Cases covered with this coating are kept in air for 10-12 hours, then heat treatment is carried out at 800-1000 ° C.
№пытани обмазки показали, что адгези обмазки к мупитокремнеземистому мёп риапу наконечников термопар увеличиваетс с повьшением темйературы отверждени . Срок службы термопар в наконечниках , защищенных обмазкой, увеличиваетс в 1,5 раза, нри этом обеспечиваетс высока стойкость покрыти при температуре до 16 ОО С,The coating tests showed that the adhesion of the coating to the silicon-dusty thermopair tip increases with an increase in the temperature of curing. The service life of thermocouples in tips protected by coating is increased by 1.5 times, which ensures high resistance of the coating at temperatures up to 16 OO C,
По сравнению с известной обмазкой технологи приготовлени зашитеой обмазки упрощаетс за счет уменьшени числа ингредиентов. ЖизнеспособностьCompared with the known coating, the process of preparing the sewn coating is simplified by reducing the number of ingredients. Viability
смеси увеличиваетс в 3 раза: с 0,5 ч у известной до 1,5 ч у преплагаемой обмазки . Уменьшаетс врем изготовлени чехла термонары за счет сокращени времени сушки обмазки в 2 раза.the mixture is increased 3 times: from 0.5 h in the known one up to 1.5 h in the preplaced coating. The time of manufacture of the thermonar cover is reduced by reducing the drying time of the coating by 2 times.
Защитную обмазку можно использовать в качестве неорганического кле дл закреплени керамических чехлов в стальных гильзах металлической арматуры термопар.Protective coating can be used as an inorganic adhesive for fixing ceramic covers in steel sleeves of metal thermocouple fittings.
