Bulogin Ceramic na Alumina Mai Juriya da Lalacewa Mai Aiki Mai Kyau

Bulogin yumbu mai jure lalacewa na alumina mafita ce ta kariya ta musamman wacce aka ƙera musamman don yanayin da ake yawan lalacewa kamar injin niƙa ƙwallo, injin niƙa mai motsawa, bututun mai, da bututun mai. Ba kamar faranti na layi na gargajiya ba, tubalinmu yana da tsari mai kauri wanda ke cimma shigarwa ta hanyar injin ta hanyar haɗin harshe da rami daidai. Wannan ƙira tana kawar da gibin kai tsaye tsakanin tubali, tana hana slurry da ƙananan barbashi su lalata harsashin kayan aiki. Mafi mahimmanci, yana rarraba nauyin tasirin da aka tsara daidai ga tubalin da ke kusa, wanda ke ƙara juriyar rufin gaba ɗaya ga spalling da girgizar injiniya. Idan aka haɗa shi da manne mai ƙarfi, tsarin haɗakar da aka ƙera yana tabbatar da cewa layin ya kasance yana da alaƙa da substrate ko da a ƙarƙashin juyawa mai sauri ko girgiza mai tsanani, yana ba da kariya mai ɗorewa.

Dangane da aikin kayan aiki, ana ƙera tubalin yumbu na alumina daga foda mai tsarki na α-alumina ta hanyar matsewa mai ƙarfi da kuma sintering mai zafi sosai, tare da abun ciki na alumina daga 92% zuwa 99% kuma ana iya daidaita shi gaba ɗaya zuwa takamaiman yanayin aiki. Idan aka ɗauki tubalin alumina 95% da aka fi amfani da shi a matsayin misali, halayen da aka saba da su sune: yawan yawa ≥ 3.65 g/cm³, shan ruwa < 0.01%, taurin Rockwell HRA ≥ 86, ƙarfin matsi ≥ 2000 MPa, ƙarfin lanƙwasa ≥ 300 MPa, da kuma taurin karyewa > 3.5 MPa·m½. A cikin gwaje-gwajen gogewa na danshi na yau da kullun, asarar taro ta fi ƙasa da kashi 90% fiye da na ƙarfe manganese na gargajiya, kuma ƙimar lalacewa gabaɗaya ƙasa da 0.02%. Waɗannan alkaluma ba iyakokin nazari ba ne, amma bayanai ne da aka tsara daga tsarin kula da inganci mai tsauri, wanda ke tabbatar da cewa kowace ƙungiya da aka kawo a kowane lokaci tana fassara juriyar lalacewa, juriyar tsatsa, da kuma taurin tasiri zuwa ƙarancin lokacin aiki da kuma wadatar kayan aiki ga abokan cinikinmu.

A yau, an yi amfani da tubalin yumbu namu masu ɗaurewa masu jure lalacewa a fannoni daban-daban na hakar ma'adinai, siminti, samar da wutar lantarki, yumbu, da masana'antun sinadarai masu kyau don kayan aikin niƙa da jigilar kayayyaki daban-daban. Ko da yake muna jure wa ƙwallan ƙarfe da slurry mai ƙarfi a cikin injin niƙa na ƙarfe, ko kuma muna jure wa ci gaba da yanke foda mai sauri a gwiwar hannu mai ɗaukar iska, ko kuma muna jure wa lalacewar lalatawar slurries mai guba a cikin bututun mai kauri, waɗannan tubalan suna nuna tsawon rai na aiki fiye da na kayan da aka saba amfani da su don jure lalacewa.
