Muaj ntau hom refractory cib, nrog ntau pua ntawm lawv. Muaj cov kua qaub, nruab nrab, alkaline, thiab lwm yam, nrog cov khoom zoo sib xws thiab kev siv sib txawv. Yog tias tsis tuaj yeem xaiv cov tshuaj khib nyiab uas tsim nyog tsis raug, thaum lub sij hawm siv high - kub, siab - cov pa roj los yog slag yuav ua ntej erode los yog ntxuav cov refractory mortar, ntxiv exacerbating kev puas tsuaj rau lub cib hauv ob sab phlu thiab txo cov kev pab cuam lub neej ntawm refractory cib hauv ob sab phlu. Yog li ntawd nws yog ib qho tseem ceeb uas yuav tau xaiv refractory mortar rau kev tsim kho ntawm refractory bricks.
Refractory av nkos yog ib yam khoom uas tsis muaj refractory muaj li ntawm cov ntaub ntawv hmoov thiab binders los npaj refractory slurry, feem ntau yog siv rau cov pob qij txha thiab txheej cov ntaub ntawv ntawm refractory cib masonry.
Thaum refractory mortar yog siv los ua cov khoom sib koom ua ke, qhov zoo ntawm cov tshuaj khib nyiab refractory muaj feem cuam tshuam rau qhov zoo ntawm masonry. Refractory mortar tuaj yeem kho qhov yuam kev loj thiab cov duab tsis zoo ntawm cov cib refractory, xyuas kom muaj kev sib luag thiab kev sib npaug ntawm cov masonry, thiab tsim kom muaj zog thiab nruj tag nrho ntawm masonry los tiv thaiv kev puas tsuaj sab nraud thiab yaig los ntawm masonry thiab molten kua.
Thaum refractory mortar yog siv los ua txheej txheej, nws tuaj yeem txhim kho cov slag tsis kam thiab kev ua haujlwm kub ntawm masonry, thiab ua kom lub neej ntev ntawm lub cub tawg. Siv rau saum npoo ntawm refractory bricks nyob rau hauv masonry ntawm chav tsev kub, thiab sinter ua ke nrog masonry thaum lub sij hawm siab - kub siv.
Kev xaiv cov cib refractory yuav tsum siv cov av nplaum refractory nrog cov khoom siv tib yam, xws li cov av nplaum refractory av nplaum rau tso cov av nplaum cib thiab siab alumina refractory av nplaum rau tso siab alumina cib. Kev tsim kho ntawm magnesia carbon bricks yuav tsum tau siv magnesia refractory mortar, thiab lwm yam
