Yog tias koj yuav quav lub qhov cub lossis qhov cub koj tus kheej hauv koj lub tebchaws, ces koj paub txog qhov nyuaj ntawm cov txheej txheem no txawm tias tsis muaj peb cov lus qhia. Hmoov tsis zoo, cov neeg pib tshiab tsis tas yuav paub tias txawm tias nrog kev xaiv cov khoom siv rau txoj haujlwm no, cov teeb meem yuav tshwm sim. Piv txwv li, koj puas paub tias lub qhov cub hluav taws kub yog dab tsi thiab yog vim li cas lub tshuab hluav taws xob xav tau nws?
Rau cov qhov cub hauv tsev, siv cov alumina tshwj xeeb, ua los ntawm cov khoom sib xyaw tshwj xeeb ntawm quartz thiab cov av nplaum refractory. Lub tom kawg yog zoo dua lub npe hu ua "chamotte av nplaum". Nws yog qhov xwm txheej no uas tau muab lub npe rau cov khoom tshwm sim.
Los ntawm txoj kev, fireclay cib muaj txog li 70% ntawm cov av nplaum, uas txiav txim siab nws cov khoom ua haujlwm siab. Nws raug rho tawm haujlwm ntawm qhov kub thiab txias, feem ntau yog siv lub tshuab tswj hwm lub computer kom ua tau zoo dua.
Qhov tseeb yog tias ntawm qhov sib txawv me ntsis nce mus rau qib (uas feem ntau tshwm sim ntawm cov tuam txhab lag luam ib nrab), fireclay cib tau npog nrog cov yeeb yaj kiab tshwj xeeb, uas ua rau nws tsis tuaj yeem ua rau cov masonry ib txwm, txij li cov binder tov. tsis kho rau nws. Vim nws cov xim tshwj xeeb, xws li pov tseg yog hu ua "hlau ore". Tsis txhob xav tias nws tsis muaj txiaj ntsig: vim yog cov yeeb yaj kiab heev, nws muaj cov khoom tiv thaiv dej zoo heev, uas yog vim li cas cov neeg tsim khoom uas nteg hauv qab daus los ntawm cov khoom siv no poob rau hauv kev hlub nrog nws.
Ib txwm muaj hluav taws cib cib yog tus cwj pwm los ntawm cov nplua nuj straw-daj xim, cov qauv ntom ntom, thiab cov qauv granular tshwj xeeb. Nws tsis yog tsuas yog hluav taws kub heev (thov dhau 1000 degrees Celsius), tab sis kuj tuaj yeem tiv taus cov tshuaj lom neeg ib puag ncig ntev.
Ntawm lwm yam, nws cov yam ntxwv tshwj xeeb yog lub peev xwm los khaws cov cua sov uas tshwm sim. Nws yog vim li no tias cov furnaces nyob rau hauv masonry uas hom cib no tau siv sov li qeeb qeeb, tab sis muab cov cua sov tsis sib xws ntawm chav tsev thiab kub kub stability nyob rau hauv nws. Qhov no yog qhov tseem ceeb heev, vim qhov tsis zoo ntawm qhov cub cua sov yog nws qhov kev dhia txhua hnub.
Yog li ntawd, cov cib hluav taws xob, cov yam ntxwv uas tso cai rau nws siv hauv qhov chaw nyuaj tshaj plaws, yuav tsum yog qhov zoo tshaj plaws. Nws txoj kev xaiv yuav tsum mus kom ze nrog lub luag haujlwm loj tshaj plaws. Coj mus rhaub rau ntawm cov khoom yuav khoom: ntawm kev cuam tshuamKoj yuav tsum hnov ib lub suab tshwj xeeb, zoo ib yam li hlau. Yog tias koj ntaus nws, ces ib lub cib ntawm hom no yuav tsum tau faib ua tuab tuab. Nyob rau hauv rooj plaub thaum cov khoom "refractory" tsis ua raws li cov kev cai no, koj yuav tsum xav txog nws keeb kwm thiab tsis kam yuav.
Qhov tseeb yog qhov tsis muaj qhov ntsuas tau zoo qhia tau hais tias tsis muaj kev tua hluav taws, thaum qhov ntsuas kub tsis tau mus txog hauv qhov cub. Qhov txaus ntshai ntawm cov khoom no yog nyob rau hauv nws hygroscopicity, uas tshaj qhov ntawd txawm rau cov cib zoo tib yam. Yog tias koj tsim lub cub tawg tawm ntawm cov khoom siv no, nws yuav poob sib nrug hauv ob peb xyoos.
Ua tib zoo saib xyuas qhov hnyav ntawm fireclay cib: nws yuav tsum siab dua li cov niaj hnub ceramic ntau yam. Nws tuaj yeem yog los ntawm 2.4 txog 6 kg, nyob ntawm hom thiab qhov loj ntawm cov khoom.
