ke eng mullite refractory setene?

Mocheso oa lelakabe le tloaelehileng ke ofe? Ka kakaretso, mocheso o phahameng ka ho fetisisa oa lelakabe ke hoo e ka bang 500°C. Ha e le hantle, mocheso oa lelakabe oa lisebelisoa tse fapaneng tse tukang o tla fapana. Mocheso o phahameng ka ho fetisisa oa li-mullite refractories ke ofe? Ho ea ka tekanyetso ea teko, mocheso o hanyetsanang oa litene tsa mullite refractory e lokela ho ba ho pota 1200 ℃-1700 ℃! Khopolo ee ke efe? Mocheso oa ho etsa tšepe hangata o pota-potile 1300-1500 ℃. Litene tse refractory tsa Laishi li ka mamella teko ea tšepe e qhibilihisitsoeng ka nako e itseng.

Khethollo ea litene tsa mullite refractory e arotsoe haholo ka lihlopha tse 7, haholo-holo mg-23, mg-25, mg-26, mg-27, mg-28, mg-30 le mg-32. Ha sekhahla sa phetoho ea terata e futhumatsang e le ka tlase ho 2%, mocheso o lumellanang oa teko ke 1230 ℃, 1350 ℃, 1400 ℃, 1450 ℃, 1510 ℃, 1620 ℃, 1730 ℃.

Taba ea bobeli, matšoao a tlhahlobo ea ‘mele le ea lik’hemik’hale a litene tsa mullite refractory haholo-holo a kenyelletsa dikahare tsa alumina, dikahare tsa oxide tsa tšepe, bongata bo bongata, matla a hatellang mochesong oa kamore, ho futhumatsa sekhahla sa phetoho e sa feleng, conductivity ea mocheso, mocheso o bonolo oa 0.05Mpa, ts’ebetso ea anti-stripping le matšoao a mang. Ho hlalositsoe hore ho metha ho teteana ha linear le linear density tsa mullite refractories ke senotlolo sa ho metha ho hanyetsa ha eona mollong.

Joale, matšoao a tlhahlobo bakeng sa ponahalo le ho kheloha ho lumelletsoeng ha litene tsa mullite refractory haholo-holo li kenyelletsa sebopeho le boholo, ho kheloha boholo bo lumelletsoeng, ho kheloha ho sotha, bolelele ba sekhutlo, bolelele ba lehlakoreng, bophara ba lesoba, bolelele ba sekoti le ho kheloha ha moeli. Ho lokela ho hlokomeloe hore bakeng sa mefuta e meng e khethehileng ea litene tsa mullite refractory, bolelele bo lumelletsoeng ba crack bo ka khethoa ho latela tumellano ea phepelo le tlhokeho.
