Thaum nws los txog rau qhov kub thiab txias ib puag ncig - los ntawm kev lag luam furnaces mus rau qhov chaw nyob qhov cub - ib yam khoom sawv tawm raws li cov pob txha ntawm kev ncaj ncees:av nplaum refractory mortar. Tsim los tiv taus cua sov, tshuaj yaig, thiab thermal shock, qhov tshwj xeeb mortar no yog ntau tshaj li "kua nplaum" rau cov cib refractory. Nws yog ib qho tseem ceeb tivthaiv uas ua kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab siv tau ntev hauv cov ntawv thov uas cov mortars yuav tawg. Txawm hais tias koj nyob hauv kev tsim khoom, kev tsim kho, lossis kev txhim kho hauv tsev DIY, kev nkag siab txog kev siv thiab cov txiaj ntsig ntawm av nplaum refractory mortar tuaj yeem hloov pauv koj cov haujlwm kub.
Ua ntej thiab qhov tseem ceeb tshaj plaws, kev lag luam furnaces thiab kilns yog thawj qhov chaw ua si rau av nplaum refractory mortar. Hauv steel mills, iav factories, cement nroj tsuag, thiab cov chaw tsim khoom ceramic, furnaces ua haujlwm ntawm qhov kub siab tshaj 1,000 ° C (1,832 ° F) rau cov xuab moos lossis hnub kawg. Ordinary Portland cement mortar melts lossis decomposes ntawm qhov hnyav, ua rau kev ua haujlwm tsis ua haujlwm, xau, thiab nqi poob qis. Cov av nplaum refractory mortar, txawm li cas los xij, yog tsim los nrog cov av nplaum uas muaj purity, silica, thiab lwm yam refractory aggregates uas khaws lawv cov kev sib raug zoo thiab cov duab ntawm cov kub kub no. Nws kaw qhov sib txawv ntawm cov cib refractory, tiv thaiv kom tsis txhob muaj cua sov uas tuaj yeem txo lub zog ua haujlwm txog li 30%. Rau cov neeg ua haujlwm hauv kev lag luam, qhov no txhais tau tias txo qis nqi hluav taws xob, txo kev cuam tshuam kev txij nkawm, thiab ua raws li cov qauv kev nyab xeeb nruj.
Tshaj li kev lag luam hnyav, av nplaum refractory mortar yog ib qho tseem ceeb hauv kev lag luam thiab thaj chaw cua sov. Lub qhov cub, qhov cub hluav taws kub, thiab cov kab hluav taws xob tso siab rau nws los tsim kom muaj kev ruaj ntseg, tiv thaiv tshav kub. Xav txog qhov teeb pom kev zoo hauv koj chav nyob tsuas yog kom muaj cov mortar tuav koj lub qhov cub cib ua ke tawg thiab tso cov pa phem - qhov no yog qhov kev pheej hmoo ntawm kev siv cov tshuaj khib nyiab uas tsis yog refractory. Av nplaum refractory mortar tsis tsuas yog tiv taus qhov rov ua cua sov thiab cua txias ntawm lub qhov cub hauv tsev, tab sis kuj tiv thaiv cov khoom siv hluav taws xob los ntawm hluav taws kub los yog thee. Nws yog ib qho yooj yim los sib tov thiab thov, ua rau nws yog ib qho kev xaiv sab saum toj rau cov kws tshaj lij masons thiab DIY enthusiasts ib yam nkaus. Cov tswv tsev nqis peev hauv lub qhov cub tshiab lossis kho qhov qub yuav pom tias siv cov av nplaum refractory mortar ua kom lawv cov cua sov ua haujlwm tau ntau xyoo yam tsis muaj kev cuam tshuam txog kev nyab xeeb.
Lwm daim ntawv thov tseem ceeb yog petrochemical thiab metallurgical txheej txheem. Refineries, smelters, thiab foundries cuam tshuam nrog tsis tsuas yog kub kub xwb tab sis kuj aggressive tshuaj chemicals - acids, alkalis, thiab molten hlau uas yuav rhuav tshem cov pa mortars. Av nplaum refractory mortar's chemical inertness ua rau nws zoo tagnrho rau hauv ob sab phlu cov hlab ntsha, crucibles, thiab pa system. Nws tsim ib lub foob kaw ntom nti uas tiv thaiv kom tsis txhob muaj cov khoom phom sij, tiv thaiv cov neeg ua haujlwm thiab ib puag ncig. Nyob rau hauv aluminium smelting, piv txwv li, av nplaum refractory mortar yog siv rau kab electrolytic hlwb, qhov uas nws resists corrosion los ntawm molten txhuas thiab fluoride ntsev. Qhov kev ntseeg siab no yog vim li cas nws yog qhov kev xaiv zoo tshaj plaws hauv kev lag luam uas txawm tias qhov ua tsis tiav tsawg tshaj plaws tuaj yeem muaj qhov cuam tshuam loj heev.
Av nplaum refractory mortar tseem ua lub luag haujlwm tseem ceeb hauv pizza ncu thiab chav ua noj ua haus. Wood-fired pizza cubs ua haujlwm ntawm qhov kub ntawm 400 ° C thiab 500 ° C (752 ° F thiab 932 ° F), yuav tsum muaj cov tshuaj khib nyiab uas tuaj yeem siv cov cua kub hnyav yam tsis muaj kev sib tsoo lossis poob adhesion. Cov kws tshaj lij pizzerias thiab cov kws ua zaub mov hauv tsev zoo ib yam ntseeg cov av nplaum refractory mortar los tsim thiab kho cov ncu, vim nws ua kom muaj cua sov zoo sib xws thiab tiv thaiv cov pa taws lossis cua sov los ntawm kev khiav tawm. Hauv kev lag luam chav ua noj, nws tau siv los ua kab grills, rotisseries, thiab lwm yam khoom siv cua sov, tswj cov qauv kev nyiam huv los ntawm kev tiv thaiv cov khoom noj los ntawm kev nkag mus rau hauv cov khib nyiab tawg.
Yuav ua li cas teev cov av nplaum refractory mortar sib nrug los ntawm lwm cov ntaub ntawv refractory? Nws versatility thiab nqi-zoo. Tsis zoo li high-alumina lossis silica mortar, uas yog tsim rau ultra-siab kub tab sis tuaj nrog tus nqi siab dua, av nplaum refractory mortar sib npaug kev ua tau zoo thiab pheej yig rau feem ntau cov ntawv thov kub. Nws muaj nyob rau hauv daim ntawv hmoov, uas tuaj yeem tov nrog dej ntawm qhov chaw mus rau qhov xav tau sib xws, txo cov khib nyiab thiab cov nqi tsheb thauj mus los. Tsis tas li ntawd, nws muaj peev xwm ua tau zoo heev - cov masons tuaj yeem yooj yim tsim thiab du, ua kom muaj kev sib raug zoo ntawm cov cib.
Xaiv txoj cai av nplaum refractory mortar yog qhov tseem ceeb rau koj txoj haujlwm ua tiav. Nrhiav cov khoom uas ua tau raws li cov qauv kev lag luam, xws li ASTM C199, uas qhia txog qhov yuav tsum tau ua rau refractory mortar. Xav txog qhov kub siab tshaj plaws ntawm koj daim ntawv thov, vim qee cov av nplaum mortars yog tsim los rau cov cua sov ntau dua li lwm tus. Rau kev lag luam tej yaam num, xaiv rau mortar nrog ntxiv additives uas txhim khu thermal shock kuj thiab tshuaj stability. Rau kev siv hauv tsev, tus qauv av nplaum refractory mortar yuav txaus rau feem ntau qhov cub thiab qhov cub.
Hauv kev xaus, av nplaum refractory mortar yog ib qho khoom siv tseem ceeb hauv txhua daim ntawv thov uas muaj qhov kub thiab txias. Los ntawm cov khoom siv hluav taws xob mus rau lub qhov cub hauv tsev, nws muab lub zog, tiv thaiv tshav kub, thiab ua haujlwm ntev uas yuav tsum tau ua kom cov qauv muaj kev nyab xeeb thiab ua haujlwm zoo. Nws ntau yam kev siv, tus nqi-zoo, thiab kev siv yooj yim ua rau nws xaiv rau cov kws tshaj lij thiab DIYers thoob plaws kev lag luam. Yog tias koj tab tom npaj qhov project kub, tsis txhob khom rau cov mortar zoo tib yam - nqis peev hauv av nplaum refractory mortar thiab xyuas kom koj cov haujlwm ua haujlwm tau zoo ntawm lub sijhawm.
