Yadda ake rarrabewa tsakanin nagarta da mara kyau yayin siyan manyan tubalin alumina?

Yadda ake rarrabe ingancin manyan tubalin alumina lokacin siyan manyan tubalin alumina? A gefe guda, ana iya lura da shi da ido, a gefe guda kuma, ana iya gano shi da rarrabuwa.

Abubuwa biyu da idanu tsirara suka lura da su:

A. Najasa kazanta

Kallon abubuwan da ke ƙazantawa a saman bulo masu ƙyalli, galibi muna ganin wasu baƙaƙe a saman manyan tubalin alumina. Waɗannan ƙazanta ne a cikin albarkatun ƙasa. A ka’idar, ƙarancin ƙazanta, ya fi kyau, saboda waɗannan ƙazanta galibi sunadaran ƙarfe ne. , An rage shi kawai zuwa narkakkar baƙin ƙarfe da ke gudana a cikin yanayin zafi mai zafi na makera, yana haifar da lalacewar tsarin tubalin mai ƙyalli, sannan kuma yana shafar rayuwar sabis na tubalin mai ƙin. A matsayin samfur na masana’antu, ingancin bulo mai tsaurin kai tsaye yana shafar samarwa da farashin kayan aikin. Bulo mai ƙanƙantar da kai ba kawai zai haifar da yajin aikin gyare -gyare daban -daban a cikin samarwa ba, haɓaka ƙimar samarwa, amma kuma zai haɓaka gini da samarwa. Ƙarin haɗarin ɓoye waɗanda ba za a iya tantance su ba.

B. Launin kamanni da lubricity na ƙasa

Ganin bulo mai ƙyalƙyali, muna buƙatar ganin launi na bayyanar da lubricity na tubalin. Ingancin wasu bulo masu ƙyalƙyali ba su da kyau sosai, kuma ƙoshin lubricity ɗin yana da ƙanƙanta sosai, wanda ke haifar da ƙarfin tubalin da ke hanawa. Daidaitaccen bayyanar da launi na bulo mai ƙyalli yana nuna ko kayan sun cakuɗe daidai lokacin samar da bulo mai ƙyalli. Rarraba kayan da ba daidai ba zai haifar da rarrabuwar kawuna na ƙarfin tubalin mai ƙin yarda, sannan a rage ƙarfin gaba ɗaya da rayuwar sabis na tubalin da ke ƙanƙantar da kai.

Manyan mahimman abubuwa guda uku sun bambanta ta hanyar ganowa:

A. Tsayayyar slag

Babban tubalin alumina ya ƙunshi ƙarin Al2O3, wanda shine abu mai tsaurin tsaka tsaki kuma ana iya amfani dashi a cikin yanayin alkaline ko acidic. Saboda yana ƙunshe da silica silicon SIO2, juriya na slag a cikin yanayin alkaline ya fi wancan a cikin yanayin acidic.

B. Load softening zazzabi

Saboda samfuran manyan alumina suna da babban Al2O3, ƙarancin ƙazanta, da ƙaramin gilashi mai ɗumi, zafin zazzabin da ake ɗauka ya fi na tubalin yumɓu, amma saboda lu’ulu’u na mullite ba su samar da tsarin cibiyar sadarwa ba, yawan zafin jiki na amfani ba shi da kyau kamar na raunin siliceous. .

C. Sauyi

Rage girman manyan tubalin alumina ya fi na tubalin yumɓu, har ya kai digiri 1750 na Celsius zuwa digiri 1790 na Celsius, wanda shine kayan ƙyama masu inganci.

Abin da ke sama shine hanyar rarrabe ingancin manyan tubalin alumina, ina fatan zai taimaka muku.
