Gabaɗaya, bai kamata a yi amfani da tubalin aluminum masu tsayi a cikin tanderun yanayi na alkaline ba. Saboda matsakaicin alkaline da acidic suma suna da chlorine, zai shiga zurfin yadudduka na manyan bulogin alumina a cikin nau'in gradient, wanda zai sa bulo mai jujjuyawa ya rushe.
Babban tubali na aluminum bayan yashewar yanayin alkaline shine fashewar kwance. Yazawar ta ƙunshi launin toka mai mai, iskar gas mai ƙonewa, da kuma abubuwan alkaline a cikin wasu samfuran. Wadannan abubuwan da aka gyara suna amsawa tare da lokacin gilashin da dutsen mullite a cikin babban bulo na aluminum.
Babban tubali na aluminium wanda aka lalatar da alkaline zai bayyana a saman. Har ila yau, ƙona mahadi na iskar gas za su haifar da nitrate nitrate, sedimentation a cikin rata na manyan tubalin aluminum; Halin da glaciers ya haifar zai samar da wani sabon lokaci mai rikitarwa. Lokacin da nitriles masu sa'a marasa ruwa suna cikin hulɗa tare da vagram da aka haifar, tasirin anti-vaporization zai faru, yana haifar da bulo mai girma na aluminum don fashe ko faduwa. Bugu da kari, thermal lalata kuma yana da matukar tsanani ga lalata bulo mai jujjuyawa. Saboda lalacewar fang quartz, Skywine, da silica crystal quartz. Yin amfani da fale-falen wuta zai zama mafi tsanani fiye da noodles mai sanyi.
Lalacewar tubalin silicon dioxide shima yana da matukar tsanani. An narkar da silica a babban bulo na aluminum -liquid lokaci. A narkewa m nitrate da low-melting batu silicon duwatsu samar da wani babban adadin ruwa lokaci. Mafi girman abun ciki na silica a cikin bulo, mafi girman adadin lokaci na ruwa. Matsakaicin ruwa mai yawa zai lalata tubalin aluminum. Silikon siliki kuma ya lalace ga tubalin. Domin ana shan siliki na kyauta, lokaci na Mo Lai Shi zai lalace. Bayan amsawar nitrate da dutsen mullite na iya haifar da haɓakar haɓakar bulo mai girma na aluminum.
Babban tubalin aluminum yana da kyakkyawan juriya ga babban zafin jiki da abrasion. Ana amfani da su sosai a cikin rufin tanderun masana'antu daban-daban, kamar tanderun fashewa, tanderun iska mai zafi, da rotary kilns. Duk da haka, a cikin tanderun masana'antu na alkaline, yin amfani da manyan tubalin alumina yana iyakance.
Abubuwan sinadarai na manyan tubalin alumina suna sa su tsayayya da tasirin yanayin acidic. Duk da haka, a cikin yanayi mai mahimmanci na alkaline, kamar simintin siminti ko tanderun gilashi, manyan bulo na aluminum za su amsa tare da alkali karfe oxides, haifar da bulo don tsagewa da tarwatse. Halin da ke tsakanin tubalin Al2O3 da alkali karfe oxides yawanci yakan haifar da samuwar gel aluminosilicate na alkali, wanda ke da ƙananan narkewa kuma yana iya gudana cikin sauƙi ta hanyar fasa.
Don magance wannan matsala, an yi amfani da dabaru da yawa don inganta juriya na manyan tubalin aluminum zuwa yanayin alkaline. Ɗaya daga cikin mafita shine ƙara magnesia ko spinel zuwa manyan tubalin alumina. Magnesia ko spinel zai amsa tare da alkali karfe oxides don samar da barga spinel bulan, wanda zai iya bunkasa juriya na Al2O3 tubalin zuwa fatattaka lalacewa ta hanyar alkali dauki. Wani bayani shine a yi amfani da murfin kariya a saman manyan tubalin alumina don hana hulɗar kai tsaye tare da yanayin alkaline.
A taƙaice, manyan tubalin aluminium suna da iyakacin aiki a cikin rufin tanderun masana'antu na alkaline. Don haɓaka juriya na tubalin Al2O3 a cikin mahallin alkaline, ya zama dole don ƙara wasu ma'adanai ko sutura don guje wa halayen cutarwa tare da alkali karfe oxides. Yana da mahimmanci don zaɓar kayan da ya dace don rufin tanderun masana'antu don rage haɗarin haɗari da adana farashi.
