Lub teeb yuag mullite cibyog tsim los ntawm high purity refractory cov ntaub ntawv, organic filling cov ntaub ntawv yog ntxiv rau raw cov ntaub ntawv. Zoo li nyob rau hauv siab siab nyob rau hauv cov khoom nqus tsev vacuum, thiab raug rho tawm nyob rau hauv kub kub rauv, organic cov ntaub ntawv raug rho tawm haujlwm thaum lub sij hawm sintering txheej txheem. Vim nws cov rwb thaiv tsev zoo heev thiab lub teeb yuag, mullite rwb thaiv tsev cib tau dav siv los ua cov txheej txheem ua haujlwm lossis cov txheej txheem rwb thaiv tsev ntawm cov cua kub kub, kom txuag hluav taws xob thiab txhim kho kev siv hluav taws xob.
Lub teeb yuag mullite cib yog cov pob zeb refractory siab heev, nws tuaj yeem liab qab cov nplaim taws ncaj, nrog cov nplaim hluav taws kub, tsis tshua muaj qhov ntom ntom, tsis tshua muaj thermal conductivity, qhov tseem ceeb ntawm lub zog txuag thiab lwm yam.
Dense Mullite cib: Nws yog cov khoom siv siab alumina refractory nrog mullite (3Al2O3.2SiO2) raws li theem tseem ceeb. Al2O3 cov ntsiab lus feem ntau yog 65-75%. Dhau li ntawm mullite theem, rau cov khoom uas tsis tshua muaj Al2O3 cov ntsiab lus, cov ntxhia muaj pes tsawg leeg kuj muaj xws li ib tug me me iav theem thiab cristobalite; Rau cov neeg uas muaj Al2O3 cov ntsiab lus siab, kuj muaj corundum. Mullite bricks yog nrog siab refractoriness, uas yuav ncav cuag 1790 degree. Lub refractoriness nyob rau hauv load yog 1600-1700 degree. Txias crushing zog yog 70-260 MPa. Thermal shock kuj tseem zoo.
Raug rho tawm mullite cib yog tsim los ntawm calcined siab alumina bauxite, ib co av nplaum los yog raw bauxite yog ntxiv raws li binding tus neeg saib xyuas, zoo li tus nyob rau hauv lub siab kub thiab raug rho tawm haujlwm kub.Fused mullite cib yog tsim los ntawm siab alumina bauxite, alumina hmoov thiab hluav taws av nplaum. Charcoal los yog coal fine particles yog siv los ua tus neeg sawv cev. Cov ntaub ntawv yog fused nyob rau hauv high kub hluav taws xob rauv. Crystalline particle loj ntawm fused mullite yog lager dua li ntawm raug rho tawm haujlwm mullite, thermal shock kuj tseem zoo dua. Kev ua tau zoo ntawm lub teeb yuag mullite cib nyob ntawm lawv cov ntsiab lus Al2O3 thiab uniformity ntawm mullite theem thiab iav theem.
