Dab tsi yog qhov sib txawv ntawm lub zog siab alkali-resistant cib thiab av nplaum cib?
Qhov hluav taws kub kub ntawm high-strength alkali-resistant bricks thiabav nplaum cibyog tib yam li cov txheej txheem cib nias, tab sis qhov sib txawv ntawm ob lub cib no yog cov txheej txheem raw khoom sib txawv, thiab sintering kub thiab sintering lub sij hawm kuj txawv. High-strength alkali-resistant bricks muaj zog alkali tsis kam, thaum av nplaum cib yog ib tug me ntsis acidic khoom thiab muaj zog tiv thaiv acid yaig. Nws yog refractory cib nrog ob qhov sib txawv kiag li. Alkali-resistant bricks feem ntau yog siv hauv cov cement rotary kilns, thiab av nplaum cib yog siv dav.
High-strength alkali-resistant bricks yuav tsum tau ntxiv nrog ib tug tej feem ntawm high-voltage porcelain, silica, bauxite hais thiab hmoov, stirred, nias nrog ib tug cib xovxwm, thiab ces sintered ntawm ib tug tej yam kub. Ntxiv ib qho kev faib ua feem ntawm hluav taws xob porcelain tuaj yeem txhim kho cov alkali tsis kam thiab lub zog ntawm alkali-resistant bricks. Qhov sib ntxiv ntawm high-voltage hluav taws xob porcelain yog 20%, thiab qhov ntxiv ntawm cov khib nyiab silica cib hmoov lossis silica hmoov yog 10%. Lub zog muaj zog alkali-resistant cib tsim muaj lub zog siab, tsis muaj porosity, thermal shock resistance, alkali tsis kam thiab qaug zog, thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev siv.
Av nplaum cib yog tsim los ntawm bauxite particle gradation thiab av nplaum hmoov. Nws yog tsim los ntawm high-pressure mechanism ntawm cib xovxwm thiab high-temperature sintering. Av nplaum cib feem ntau yog ua los ntawm mullite, cristobalite thiab iav. Lawv cov ntsiab lus txiav txim siab cov khoom ntawm av nplaum cib. Cov muaj pes tsawg leeg thiab impurity cov ntsiab lus ntawm av nplaum sib txawv nyob ntawm seb nws keeb kwm. Qhov sib xyaw ntawm av nplaum cib sib txawv heev. Tam sim no, qee cov cib khib nyiab tau ntxiv rau cov av nplaum uas ua rau hauv kev ua lag luam, thiab qhov sib txawv ntawm qhov sib txawv yog qhov ruaj khov.
High-strength alkali-resistant bricks yog siv nyob rau hauv preheaters, decomposition furnaces thiab tertiary cua ducts rau cement rotation. Cov khoom no yuav tsum muaj zog alkali-resistant bricks nrog lub zog siab, tsis muaj porosity, zoo thermal shock kuj thiab zoo heev alkali tsis kam. Av nplaum cib yog tsim rau ntau yam kev lag luam rauv hauv ob sab phlu. Piv nrog alkali-resistant bricks, nws muaj ntau yam kev siv thiab ib tug loj feem ntawm kev siv.
