Kaolin muaj siab refractoriness, feem ntau siv los tsim cov ntaub ntawv refractory, nws cov khoom muaj qhov kub thiab txias tsis kam, thiab muaj peev xwm dais load ntawm qhov kub thiab txias yam tsis muaj deformation, kaolin pob zeb yog cov khoom tseem ceeb, nrog rau bentonite thiab bauxite, raws li nws qhov kub thiab txias. kuj, hu ua refractory av nplaum. Nyob rau hauv Suav teb, lub refractory ntau dua 1580 degree av nplaum, refractory ntau dua 1770 degree bauxite, feem ntau hu ua refractory av nplaum, lub qub muab faib ua av nplaum tawv, mos av nplaum, semi-mos av nplaum, lub tom kawg hu ua high alumina av nplaum, ib co xim Tuam Tshoj. Kaolin Clay, tsis tuaj yeem siv rau ceramics thiab papermaking, tab sis nws yog ib qho zoo raw khoom ntawm refractory, yog li cov khoom siv refractory yog ib qho lag luam tseem ceeb rau kev siv dav hauv kaolin.
Muaj ob lub ntsiab ntawm cov khoom siv refractory rau Tuam Tshoj Kaolin Clay: refractory cib, silicon aluminium paj rwb. Tus qub tsis tsawg dua 1730 degree refractoriness, 2 × 105Pa load softening pib kub tsis tsawg tshaj li 1350 degree, refractoring kab shrinkage tsawg tshaj li 0.5 feem pua (1400 degree, 2h), raws li qhov yuav tsum tau ua ntau qhov ntau thiab tsawg thiab cov duab ntawm firebrick, tom kawg yog ib yam ntawm lub teeb refractory rwb thaiv tsev, nws txoj kev tsim yog siv kaolin, tom qab 1000-1100 degree roasting, Tom qab ntawd cov ore yog melted los ntawm arc rauv ntawm 2000 degree thiab tshuab. rau hauv paj rwb nyob rau hauv kev kub ceev cua ntws.
Kaolin tuaj yeem siv rau hauv kev tsim cov khoom siv refractory, xws li firebrick, refractory enamel, thiab lwm yam. Vim nws cov hluav taws kub zoo, nws tuaj yeem siv los ua cov khoom siv hluav taws kub kom tiv taus kub. Refractory enamel yog ib yam khoom siv hluav taws xob tiv thaiv corrosion, uas tuaj yeem siv los ua cov yeeb nkab refractory, refractory lauj kaub thiab refractory furnace. Tuam Tshoj Kaolin Clay kuj tseem siv tau los ua cov txheej txheem refractory, xws li cov txheej txheem refractory, refractory anticorrosive txheej thiab lwm yam. Nws muaj cov yam ntxwv tsis muaj tshuaj lom, tiv thaiv corrosion thiab hnav tsis kam, uas tuaj yeem siv los tiv thaiv cov hlau nto ntawm corrosion thiab ua rau lub neej ntev ntawm cov hlau nto. Kaolin kuj tseem siv tau los ua cov ntaub ntawv refractory insulating, xws li refractory insulating fiber ntaub, refractory insulating xav, thiab lwm yam. Cov ntaub ntawv refractory insulating no muaj cov hluav taws kub zoo thiab rwb thaiv tsev zoo thiab tuaj yeem siv los tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob.
Txawm li cas los xij, qhov piv ntawm A1203 thiab Si{{10}}2 cov ntsiab lus hauv Tuam Tshoj Kaolin Clay ncaj qha cuam tshuam rau kev hloov pauv ntawm refractorily. Hauv cov kaolin zoo, A1203/Si02 tus nqi feem ntau yog 0. Thaum qhov sib piv ntau dua 0.85, Lub xub ntiag ntawm aluminium-nplua nuj minerals yuav txhim kho lub refractability, thaum lub xub ntiag ntawm quartz yuav txo tau cov refractability thaum cov ntsiab lus ntawm Tuam Tshoj Kaolin av nplaum yog tsawg dua 0.7. Tsis tas li ntawd, cov ntsiab lus ntawm Fe203, TiO2, K2O hauv kaolin yuav txo cov refractoriness, nrog rau qee qhov kev puas tsuaj.
Kaolin feem ntau yog siv los ua ib qho khoom siv los yog muab tub lim los txhim kho lub zog thiab hnav tsis kam ntawm cov khoom. Kaolin yog cov hmoov dawb uas tau txais los ntawm kev ua cov kaolinite, uas muaj cov hluav taws kub zoo heev thiab kev ruaj ntseg tshuaj. Hauv cov ntaub ntawv refractory, kaolin feem ntau yog siv los ua ib qho ntawm cov khoom tseem ceeb rau kev tsim cov khoom siv refractory thiab cov khoom siv ceramic. Tuam Tshoj Kaolin Clay yog ib qho tseem ceeb heev refractory khoom nrog zoo heev kub tsis kam, tshuaj stability thiab txhua yam khoom. Nws yog dav siv nyob rau hauv ntau yam kub kub industrial teb.
