2. Ina ake amfani da tubalin alumina masu yawa a cikin tanderun fashewa?

An gina tubalan aluminum masu ƙarfi a kan sandar tanderu tanderu mai fashewa. Shaft ɗin tanderu yana cikin ɓangaren sama na tanderu mai fashewa. Girman ta yana faɗaɗa a hankali daga sama zuwa ƙasa don daidaitawa da faɗaɗa zafi na caji da rage gogayya na bangon tanderu akan caji. Jikin tanderu yana mamaye tanderu mai fashewa. 50%-60% na tsayin da ya dace. A cikin wannan yanayi, rufin tanderu yana buƙatar cika irin waɗannan buƙatu, kuma halayen tubalan alumina masu ƙarfi sune ƙarfin juriya, zafin jiki mai laushi a ƙarƙashin kaya, juriyar acid, juriyar alkali, juriya mai ƙarfi ga yashewar slag, da juriya mai kyau ga lalacewa. Ana iya gamsuwa da shi, don haka ya dace sosai don jikin tanderu mai fashewa ya kasance an lulluɓe shi da tubalan alumina masu ƙarfi.

Wannan gabatarwa ce game da tubalin alumina masu tsayi don tanderun fashewa. Yanayin rufin tanderun fashewa yana da rikitarwa kuma akwai nau'ikan kayan da ba sa jurewa da ake amfani da su. Tubalin alumina masu tsayi suna ɗaya daga cikinsu. Akwai ƙayyadaddun bayanai 3-5 na tubalin alumina masu tsayi da ake amfani da su. Ana iya amfani da tubalin alumina masu tsayi na Robert a cikin nau'ikan murhu daban-daban. Idan ya cancanta, tuntuɓe mu.
