Ua ntej ntawm tag nrho cov, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv ntawm refractory av nkos, refractory cement thiab refractory castables.
Refractory mortar, tseem hu ua refractory av nkos, yog ib qho kev sib koom ua ke lossis cov khoom sib txuas thaum siv cov pob zeb refractory cib. Refractory av nkos yog siv thaum hluav taws cib siv los tsim cov masonry nyob rau hauv lub combustion chamber. Nyob ntawm cov khoom siv ntawm cov hluav taws kub, cov ntaub ntawv sib txawv ntawm cov av nkos refractory yog siv, xws li av nplaum av rau av nplaum cib, high-alumina av nkos rau siab alumina cib, thiab lwm yam.
Refractory cement yog cov khoom siv kub-resistant cementing, tseem hu ua binder. Raws li qhov kub thiab txias, nws tsis tuaj yeem siv ib leeg, yuav tsum tau teeb tsa nrog qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv refractory aggregate los yog high-aluminium aggregate, refractory xuab zeb sib tov, thiaj li hais tias nws muaj ib tug tej yam lub zog. Tom qab sib tov cov khoom, ntxiv ib tug npaum li cas ntawm cov dej, thiaj li hais tias ntau yam sib txawv refractory aggregates cemented ua ke nrog ib tug tej yam ntxwv lub zog thiab hnav tsis kam. Refractory cement siv ib leeg, kub tsis kam, tsis muaj zog, yooj yim rau tawg los yog spalling, tshwj xeeb tshaj yog nrog rau qhov kub thiab txias, qhov tshwm sim loj dua.
Refractory castable yog ntau hom refractory aggregates rau cov hmoov ua cov khoom siv tseem ceeb, cov cement refractory rau cov khoom siv khi, ntxiv shrinkage inhibitor, tawg-pov thawj fiber, coagulant txhawb nqa thiab lwm yam khoom siv ntxiv, nws tuaj yeem nchuav rau hauv cov ntaub ntawv tseem ceeb. , tsis muaj qhov sib txawv, nrog lub zog muaj zog thiab slag tsis kam, yog qhov kub kub ntawm cov khoom siv hluav taws xob tam sim no feem ntau siv cov khoom tsis zoo li cov khoom siv refractory. Txhawm rau ua kom lub sijhawm siv sijhawm luv luv, cov khoom siv hluav taws xob refractory castables kuj tseem tuaj yeem raug cam khwb cia hauv prefabricated qhov chaw hauv thaj chaw ncaj qha masonry siv.
Yog tias koj txaus siab rau cov khoom siv refractory, tiv tauj peb tam sim no!
