Menene bambance-bambance tsakanin manyan tubalin alumina da tubalin yumbu

a. A refractory na high-refractory alumina tubalin ne mafi girma fiye da na yumbu tubalin da Semi-Silica tubalin, kai 1750 ~ 1790 ℃, wanda shi ne wani high-sa refractory abu.

b. Load softening zafin jiki Saboda high aluminum kayayyakin da high Al2O3, m ƙazanta, kuma kasa fusible gilashin, da lodi softening zafin jiki ne mafi girma fiye da na lãka tubalin, amma saboda mullite lu’ulu’u ba su samar da tsarin cibiyar sadarwa, da lodi softening zafin jiki ne har yanzu Ba kamar yadda. high as silica tubalin.

c. Babban tubalin alumina na juriya yana ƙunshe da ƙarin Al2O3, wanda ke kusa da kayan hana tsaka tsaki, kuma yana iya tsayayya da yashwar acid slag da alkaline slag. Saboda ya ƙunshi SiO2, ikon yin tsayayya da slag alkaline ya fi rauni fiye da na acid slag. wasu. An fi amfani da shi don rufin tanderun fashewa, murhu masu zafi mai zafi, saman tanderun lantarki, tanderun fashewar tanda, tanderun murɗawa, da rotary kilns. Bugu da kari, manyan bulogin alumina kuma ana amfani da su sosai azaman bulogin sabunta bugun zuciya, matosai don tsarin zubowa, bulogin bututun ƙarfe, da sauransu.

Duk da haka, farashin manyan tubalin alumina ya fi na tubalin yumbu, don haka ba lallai ba ne a yi amfani da tubalin alumina masu girma inda tubalin yumbu zai iya cika bukatun. Farashin manyan bulogin alumina sau da yawa yakan bambanta sosai bisa ga buƙatun abun ciki na aluminum, kuma tasirin amfani kuma ya bambanta sosai.
