budada oksaydh ee aluminiumka ah ee refractory
Alumina budada/a-alumina budada yar yar
Budada aluminiumku waa walax aan organic ahayn oo leh qaacidada kiimikada Al2O3.Waa iskudhis adag oo adag oo leh barta dhalaalaysa 2054°C iyo barta karkarinta 2980°C.Waa crystal ionic kaas oo ionize kara heerkulka sare waxaana inta badan loo isticmaalaa soo saarida alaabta dib u celinta.
Budada alumina waa alumina Al2O3 budada adag, sida caadiga ah waxaa lagu farsameeyaa budada alumina α-al2o3, budada alumina β-al2o3, budada alumina γ-al2o3 sida isticmaalka kala duwan.
α-Alumina micropowder
α budada alumina waxay leedahay sifooyin jidheed iyo kiimiko oo aad u deggan, qallafsanaan sare, iska caabin, xoog farsamo oo sarreeya, dahaarka, caabbinta heerkulka sare, qadar yar oo gubasho ah, isku-dhafka hoose ee ballaarinta kulaylka, kuleylka kuleylka wanaagsan iyo sifooyinka kale.
α alumina waxaa inta badan loo isticmaalaa sida xoqida, walax adkeysi, maaddooyinka dib-u-celinta, alaabta dhalaalaysa, iwm.
Habka wax soo saarka
Mashiinnada kubbadda alaabta ceeriin: waxay ka caawisaa inay ka saarto wasakhda, hagaajinta heerka beddelka habka toogashada, iyo kordhinta xawaaraha falcelinta;
Dubidda foornada tunnelka: wax soo saar joogto ah oo deggan waa la xaqiijin karaa, heerkulka dubantuna si sax ah ayaa loo xakamayn karaa;
Mashiinnada Kubbada Clinker: Ku shiiddo cabbirka walxaha loo baahan yahay.

Codsiga
1. Alaabooyinka dib-u-soo-celinta.Clinker sare oo alumina bauxite ah wuxuu leeyahay refractoriness ilaa 1780C, xasilloonida kiimikaad xooggan iyo sifooyin jireed oo wanaagsan.
2. Qaadashada saxda ah.Clinker-ka bauxite waxa lagu farsameeyaa budo fiican oo laga dhigay caaryaal si sax ah loo shubo.Loo isticmaalo warshadaha militariga, hawada hawada, isgaarsiinta, qalabaynta, mashiinada iyo waaxaha qalabka caafimaadka.
3. Warshadaha aluminium.Difaaca qaranka, duulista, baabuurta, qalabka korontada, kiimikooyinka, daruuraha maalinlaha ah, iwm.
4. Aluminium silicate fiber refractory;Isticmaal magnesia iyo bauxite clinker sida alaabta ceeriin, ciid iyo bauxite clinker sida alaabta ceeriin, ciid iyo bauxite clinker sida alaabta ceeriin, samaynta sibidhka bauxite, alaabta abrasive, warshadaha dhoobada iyo warshadaha kiimikada waxaa la soo saari karaa xeryahooda kala duwan ee aluminium.
