Corundum Mullite Castable Kev Piav Qhia
Corundum mullite refractory castable yog ib hom khoom siv refractory muaj zog heev uas muag hauv RS Company, uas siv tau rau hauv cement kiln. Corundum mullite castables tuaj yeem ua tau cov khoom zoo xws li lub zog crushing siab, kev ruaj khov kub siab, kev tiv thaiv thermal shock, kev hnav thiab kev tiv thaiv tshuaj lom neeg hauv cov kab ntawm lub chaw nres tsheb fais fab loj thiab lwm yam khoom siv kub siab. refractory corundum mullite castable tuaj yeem siv rau hauv steel cub tawg, cement kiln, iav cub tawg, hlau ua cub tawg, ceramic tunnel kiln thiab lwm yam.
Cov Khoom ntawm Corundum Mullite Castable
- Muaj zog heev,
- Muaj zog hnav tsis kam,
- Kev tiv thaiv kev yaig zoo,
- Kev ruaj khov thermal zoo heev,
- Kev kub siab ua haujlwm.
Cov Txheej Txheem Tsim Khoom ntawm Corundum Mullite Castable
Cov khoom siv tseem ceeb ntawm corundum mullite castable yog cov khoom sib xyaw ua ke ntawm cov txhuas oxide sib xyaw, cov khoom siv zoo mullite ntuj, thiab calcium aluminate cement ua tus neeg sawv cev rau kev sib txuas. corundum mullite refractory castable yog ua los ntawm kev kub hnyiab los ntawm lub cub tawg kev lag luam siab heev. corundum mullite flexural zog thiab compressive zog nce ua ntej thiab txo qis nrog kev nce ntawm kev kho cua sov kub. Thiab thaum alumina micro zog cov ntsiab lus yog 5%, lub zog flexural ncav cuag rau sab saum toj.
Cov khoom sib xyaw ntawm Corundum Mullite Castable
Cov ntsiab lus ntawm Al2O3 yog ntau dua 90%, thiab cov corundum mullite rwb thaiv tsev castable nrog corundum ua lub ntsiab siv lead ua ke yog sib xyaw nrog cov dispersants tsim nyog, coagulants, stainless hlau fibers, uas tau sib xyaw raws li cov mis nruj. Refractory corundum mullite castable muaj ntau yam ntxwv, xws li lub zog kub siab, hnav-resisting thiab anti-scour, siab kub conduction, kub poob siab tsis kam, corrosion tsis kam, zoo sealing thiab thaum ntxov condensation.

Daim ntawv thov ntawm Corundum Mullite Castable
Corundum mullite refractory castable muaj cov yam ntxwv ntawm kev nthuav dav zoo ib yam, kev tiv thaiv thermal zoo heev, kev ruaj khov kub siab, lub zog kub siab, kev tiv thaiv siab hauv qab kev thauj khoom, qis qhov kub siab creep rate, siab crushing zog, qis linear dimensional change rate, siab hardness, zoo tiv thaiv tshuaj corrosion, spalling thiab hnav tsis kam. Vim yog cov yam ntxwv zoo li no, corundum mullite rwb thaiv tsev castable yog ruaj khov hauv kev siv thiab uas yog dav siv rau hauv ntau yam kev lag luam kiln, kub kub cub tawg thiab lwm yam tseem ceeb ntawm kub siab, xws li:
- Boiler, lub cub tawg, lub qhov cub tawg kub, lub cub tawg cua sov,
- Qhov cub ua los ntawm cov av nplaum, qhov cub ua los ntawm cov cement, qhov cub hlawv thee,
- Qhov rooj cub tawg, qhov qhib pub, cub tawg hlau, cub tawg ua hlau,
- Chav hlawv, qhov cub tawg,
- Lub chaw fais fab loj boiler, lub qhov cub iav.
