Lub teebmullite rwb thaiv tsev bricksmuaj cov qib sib txawv, uas yuav cuam tshuam rau lawv cov rwb thaiv tsev kev ua tau zoo, refractoriness, thiab lwm yam. Feem ntau hais lus, cov ntsiab lus alumina siab dua, qhov siab dua qhov refractoriness thiab qhov zoo dua qhov ruaj khov. Tsis tas li ntawd, cov tuab ntom ntom thiab chav chav sov compressant lub zog tseem yuav sib txawv, uas yuav cuam tshuam nws cov khoom muaj peev xwm thiab lub neej. Thaum xaiv, koj tuaj yeem xaiv raws li cov cim qhia lub cev thiab tshuaj lom neeg.
Jm23/Jm26/Jm28/Jm30 nyob rau hauv lub teeb yuag mullite cib sawv cev rau cib tooj ntawm ntau qib. Lub teeb yuag mullite insulating cib ntawm cov qib sib txawv yuav txawv ntawm kev ua haujlwm rwb thaiv tsev, ntsuas lub cev thiab tshuaj lom neeg thiab cov kev siv dav dav. Yog li, dab tsi yog qhov txawv ntawm lawv?
1. Cov ntsiab lus sib txawv Al2O3
Cov ntsiab lus ntawm alumina ntawm lub teeb yuag mullite rwb thaiv tsev cib sib txawv. Cov ntsiab lus alumina ntawm JM23 yog nruab nrab ntawm 38-44%, cov ntsiab lus alumina ntawm JM26 yog nruab nrab ntawm 50-58%, cov ntsiab lus alumina ntawm JM28 yog nruab nrab ntawm 65-70%, thiab cov ntsiab lus alumina ntawm JM30 yog nyob nruab nrab ntawm 70-73%. Nws tuaj yeem pom tias qib siab dua, qhov siab dua cov ntsiab lus alumina, uas tseem yuav cuam tshuam rau nws cov thermal rwb thaiv tsev kev ua tau zoo thiab refractoriness.
2. txawv refractoriness
Lub refractoriness ntawm plaub qib ntawm lub teeb yuag mullite cib kuj txawv. Lub refractoriness ntawm JM23 yog 1350 degree, lub refractoriness ntawm JM26 yog 1430 degree, lub refractoriness ntawm JM28 yog 1540 degree, thiab lub refractoriness ntawm JM30 yog 1600 degree. Nws tuaj yeem pom tau tias qib siab dua, qhov siab dua qhov refractoriness, uas txhais tau tias qhov zoo dua qhov kev ruaj ntseg hauv qhov kub thiab txias.
3. Txawv ntim ceev
Qhov ntim ceev ntawm JM23 yog 0.6g/cm3, qhov ntim ceev ntawm JM26 thiab JM28 yog tib yam, ob qho tib si 0.8g/cm3, thiab qhov ntim ntawm JM30 yog 1g/cm3. Qhov ntim ceev yuav cuam tshuam qhov hnyav thiab thermal rwb thaiv tsev kev ua tau zoo ntawm lub cib. Feem ntau hais lus, qhov ntau dua qhov ntim ceev, lub cib hnyav dua thiab qhov ua tau zoo ntawm thermal rwb thaiv tsev.
4. Qhov sib txawv ntawm chav tsev kub compressive zog
Chav tsev kub compressive lub zog ntawm lub teeb yuag mullite rwb thaiv tsev bricks kuj txawv. Chav kub compressive zog ntawm JM23 yog 1.3Mpa, chav kub compressive zog ntawm JM26 yog 2Mpa, chav kub compressive zog ntawm JM28 yog 3Mpa, thiab chav kub compressive zog ntawm JM30 yog 3.5Mpa. Nws tuaj yeem pom tias qib siab dua, qhov siab dua ntawm chav tsev kub compressive zog, uas txhais tau hais tias lub peev xwm thauj khoom thiab kev pab cuam lub neej ntawm cib kuj yuav nce ntxiv.
Ntxiv rau qhov sib txawv saum toj no, lawv kuj tseem tuaj yeem sib txawv ntawm thermal conductivity, reburning kab hloov pauv, thiab lwm yam. Cov ntsuas no muaj kev cuam tshuam cov thermal conductivity thiab stability ntawm cov khoom, thiab kev xaiv tuaj yeem ua raws li cov lus qhia ntawm lub cev thiab tshuaj lom neeg.
