Qhov txawv ntawm Refractory Bricks thiab Ordinary Cib

Refractory bricks yog refractory ceramic blocks siv los txuas qhov cub, fireboxes, thiab furnaces. Lawv txawv ntawm cov cib thiab pob zeb zoo tib yam vim tias lawv tuaj yeem tiv taus kub txog 1800 degrees Fahrenheit. Cov tshuaj muaj pes tsawg leeg ntawm tuab refractory cib txawv ntawm cov cib zoo tib yam. Cov xim, cov duab, thiab thermal conductivity ntawm refractory cib thiab cov cib zoo tib yam kuj txawv.
huab cua kub
Refractory bricks muaj hluav taws-resistant. Lawv kuj hu ua qhov cub cib. Lawv yog siv los tsim lub qhov cub, qhov cub, thiab chav ua noj rau ua qhov cub. Lawv kuj tau siv rau kev tsim cov khoom siv me me lossis loj loj rauv taws. Lawv hnyav thiab muaj porosity tsawg. Ntawm qhov tod tes, tsis tu ncua lossis cib thiab pob zeb cib muaj ntau qhov.
daim ntawv
Cov tshuaj muaj pes tsawg leeg ntawm refractory cib suav nrog 23% alumina thiab 73% silica. Hlau oxide, titanium, thiab lwm yam hlau oxides tsim cov seem seem. Cov tshuaj tseem ceeb ntawm cov cib zoo tib yam yog silica, alumina, magnesium oxide, txiv qaub, hlau oxide, thiab alkali. Yog tias muaj ntau lossis tsawg dua li qhov xav tau ntawm ib qho ntawm cov khoom siv no, nws yuav ua rau muaj kev puas tsuaj loj rau cov cib. Nyob rau hauv cov ntaub ntawv ntawm zoo tib yam bricks, muaj pes tsawg leeg yog me ntsis bonded, thaum refractory bricks yog ntau ntom.
Xim thiab Zoo
Refractory bricks yog ib txwm dawb. Sib tov stains rau hauv slurry thaum lub sij hawm tsim cov txheej txheem kom discolor lub cib. Qee cov xim nrov muaj xws li espresso, moss ntsuab, liab, thiab dub. Cov xim tso cai rau cov cib kom phim cov kev siv nyob ib puag ncig, ib yam li cov cib zoo tib yam ua los ntawm cov xim sib txawv. Cov xim ntawm cov cib zoo tib yam txawv raws li hom av hom siv. Refractory bricks yog uniformly rectangular nyob rau hauv cov duab, thaum zoo tib yam cib tej zaum yuav muaj uneven shapes.
thermal conductivity
Lub thermal conductivity ntawm cov cib zoo tib yam yog ntau dua li cov cib refractory. Refractory bricks tuaj yeem tiv taus qhov kub thiab txias vim tias cov ceramics, hlau oxides, thiab lwm yam tshuaj additives nqus thiab tsis hloov ntawm qhov kub thiab txias. Tsawg thermal conductivity tuaj yeem muab kev siv zog ntau dua thiab cov nqi rwb thaiv tsev. Yog li ntawd, tuab refractory bricks yog siv nyob rau hauv ib puag ncig nrog huab cua los yog thermal stress. Ntoo kilns los yog furnaces yog ib co kev siv uas yuav tsum tau refractory cib. Cov khoom denser kuj muab cov cib muaj zog hnav tsis kam. Cov cib qub qub tsis haum rau cov ntawv thov no.
