Shin akwai wani bambanci tsakanin bulo da aka gyaggyarawa da siliki da tubalin ja da aka gyara?
Shin akwai wani bambanci tsakanin tubali da aka gyara da siliki da tubalin jan siliki wanda aka gyara?
Akwai nau’o’i daban-daban guda uku na tubalin silica-mo, 1550, 1650 da 1680. Ana amfani da su a yankin sauyawa na siminti rotary kiln linings na daban-daban masu girma dabam.
Idan aka kwatanta da tubalin da aka ƙera silica, tubalin jajayen siliki-mold sun fi yawa, tare da ingantaccen ƙarfi da juriya na lalata, kuma suna da tsawon rayuwar sabis. Ana amfani da shi a cikin yankin miƙa mulki na manyan siminti rotary kilns.
Kamar yadda yanayin rayuwar tubalin alkaline da ake amfani da shi a cikin babban yankin zafin jiki na manyan simintin rotary kilns yana ƙaruwa da tsayi, don haɓaka rayuwar sabis na yankin miƙa mulki. Dangane da ainihin yanayin da ake amfani da shi, masana’anta sun haɓaka tubalin silicon molybdenum mai sassauƙa da tubalin silicon corundum, waɗanda suka fi jure lalacewa da juriya.
Abun da ke cikin siliki carbide na bulo da aka ƙera ya yi ƙasa da na bulo ɗin jan bulo da aka ƙera silikon, kuma ƙarfinsa da ƙarfinsa ma sun ragu. Tuba mai sassauƙan siliki da tubalin siliki na siliki suna da matsayi mafi girma da inganci fiye da bulo da aka ƙera siliki da bulo da aka ƙera.
Ana iya amfani da tubalin silica corundum a cikin ƙona yanki na lemun tsami rotary kilns, kuma za a iya amfani da su a cikin rufi na zinc volatilization kilns.
Ma’anar juriya na tubalin silicon molybdenum shine juriya na abrasion, juriya na yashwa, juriya ga gajiya da samuwar zobe. Tsarin sintiri ya fi rikitarwa fiye da na manyan tubalin alumina.
Tun da tubalin silicon carbide yana buƙatar ƙara wani yanki na silicon carbide, taurin da abubuwan da ke cikin albarkatun ƙasa za su sa bulo ya zama ja da baki, kuma launin cyan baƙar fata shine halayen silicon carbide. Duk da haka, a lokacin sintering, wasu yashi na matashi za a yayyafa shi a kan motar kiln, kuma za a tanadi hanyar wuta mai ma’ana don harbin ya kasance daidai.
Harba tubalin da aka ƙera na silicon yana harbi a cikin yanayi mai rahusa, kuma zafin harbi ya bambanta zuwa wani ɗan lokaci don maki daban-daban, gabaɗaya tsakanin 1428 zuwa 1450 ° C. Idan yashin pad ɗin ya manne a saman bulo bayan ya fita daga cikin kiln, ana iya goge yashin kushin sannan a saka shi cikin ajiya.
A takaice, ingancin tubalin siliki da tubalin ja jajayen siliki sun bambanta, kuma girman rufin kiln ɗin da aka yi amfani da shi shima ya bambanta.
