Hauv daim ntawv thov ntawm epoxy resin castables, cov khoom zoo heev ntawm cov khoom nws tus kheej tsis txaus los lav qhov zoo thiab kev ntseeg siab ntawm cov khoom kawg. Kev tshawb fawb thiab tsim nyog siv cov tswv yim tseem tsim nyog, yuav tsum tau ua tib zoo saib xyuas kev tswj xyuas cov txheej txheem, kev ua tiav, thiab kev tswj cov txheej txheem. Kev paub txog cov txheej txheem no tuaj yeem txo qis kev tsim cov khoom tsis zoo, txhim kho cov khoom sib xws, thiab ua tiav cov khoom siv rwb thaiv tsev, kev tiv thaiv, thiab kev txhim kho cov qauv zoo.
Ua ntej, nyob rau hauv thawj theem ntawm kev npaj, qhov tseeb formulation hnyav thiab uniform dispersion yog cov tswv yim tseem ceeb. Cov khoom sib txawv ntawm cov khoom siv raw yuav tsum tau hnyav nyob rau hauv qhov kub thiab txias tsis tu ncua kom tsis txhob muaj qhov hloov pauv viscosity thiab qhov sib txawv ntawm qhov sib txawv los ntawm qhov kub thiab av noo hloov pauv. Thaum sib tov, qhov qis- pib nrawm- ua raws los ntawm kev maj mam nce nrawm yog pom zoo kom tiv thaiv kom tsis txhob muaj zog shear ntau dhau los ntawm kev nthuav tawm cov npuas huab cua los yog ua rau cov txheej txheem muab tub lim. Lub tshuab nqus tsev sib xyaw yog ib qho kev siv ntau thiab siv tau zoo degassing; Cov xwm txheej tsis zoo tuaj yeem tshem tawm cov huab cua sib xyaw thiab qis -molecular- hnyav volatiles, tso cai rau cov resin thiab muab tub lim los tsim cov ntawv cog lus ruaj khov dua, muab qhov qis- tsis xws luag slurry rau tom ntej casting.
Qhov thib ob, kev tswj dej ntws thaum lub sij hawm casting txheej txheem yog qhov tseem ceeb heev. Rau cov khoom ua haujlwm uas muaj cov txheej txheem nyuaj lossis cov kab noj me me, yuav tsum xaiv qhov qis - cov kua viscosity, thiab yuav tsum tau siv txoj kev ua kom qeeb, khov kho kom cov khoom ua kom cov txheej txheem impregnate los ntawm txheej, kom tsis txhob muaj cua nkag. Rau ntsug lossis loj planar Cheebtsam, ib tug muab tshuaj txhuam -zoo li system nrog siab dua thixotropic zog yuav siv tau los txo sagging thiab ntug buildup. Yog tias tsim nyog, segmented pouring los yog overflow channel yuav tsum tau siv los xyuas kom meej qhov tseeb thiab cov tuab tuab. Lub ambient kub thiab av noo thaum lub sij hawm pouring yuav tsum tau ruaj khov los tiv thaiv tsis xws luag xws li nto roughness thiab sab hauv cov kab nrib pleb tshwm sim los ntawm heev ceev los yog qeeb curing tshua.
Tus yuam sij rau cov txheej txheem curing yog nyob rau hauv qhov tsim nyog tsim ntawm qhov kub thiab txias profile. Rau chav -kub kho, lub sijhawm txaus yuav tsum tau tso cai los ua kom tiav cov tshuaj tiv thaiv thiab tsis txhob muaj kev ntxhov siab los ntawm kev cuam tshuam sab nraud thiab cua sov los yog txias tam sim ntawd. Rau cov cua sov-kho, ib qho kev ntsuas cua sov thiab tuav yuav tsum tau teeb tsa raws li cov khoom siv los xyuas kom meej qhov sib txawv ntawm qhov kub thiab txias thiab tiv thaiv kom tsis txhob muaj cua sov hauv cheeb tsam uas tuaj yeem ua rau kev ua haujlwm tsis zoo lossis kev ntxhov siab tawg. Rau tuab- phab ntsa lossis loj- cov khoom loj, yuav tsum tau them nyiaj tshwj xeeb rau kev kho kom zoo ntawm qhov chaw sab hauv thiab sab nraud kom tsis txhob muaj "lub plhaub tawv, mos mos" tshwm sim.
Kev saib xyuas cov txheej txheem thiab tiag tiag- kev hloov kho lub sijhawm kuj yog cov tswv yim zoo rau kev txhim kho kom zoo. Kev saib xyuas online siv cov viscometers, ntsuas kub, thiab dielectric spectrometers tso cai rau kev saib xyuas lub sijhawm ntawm slurry lub xeev thiab kev kho kom zoo. Ib qho kev tsis txaus ntseeg, xws li nce viscosity lossis kub sib txawv, yuav tsum tau kho tam sim ntawm cov txheej txheem tsis ua haujlwm lossis ncua kev ua haujlwm. Tshaj tawm -casting daws rau defoaming thiab qeeb txias pab tso tawm cov kev ntxhov siab uas seem thiab txhim kho qhov ruaj khov.
Thaum kawg, kev tswj kom zoo yuav tsum tau khaws cia thoob plaws hauv tag nrho cov txheej txheem. Kev soj ntsuam pom sai sai txheeb xyuas cov cim ntws, cov khoom tsis txaus, thiab cov npuas cua; cross-seem thiab kev ntsuas kev ua tau zoo txheeb xyuas qhov sib xws ntawm cov qauv sab hauv thiab ua raws li cov qauv kev ua tau zoo thiab hluav taws xob. Rau cov ntawv thov tseem ceeb, tsis yog- kev sim ua kom puas tsuaj ntxiv txheeb xyuas cov teeb meem muaj peev xwm, kom ntseeg tau ntev - lub sij hawm.
Hauv cov ntsiab lus, daim ntawv thov cov txheej txheem rau epoxy resin castables encompass precise formulation, uniform dispersion, flow control, curing optimization, thiab cov txheej txheem saib xyuas. Kev siv cov txheej txheem no hauv kev xyaum tsis yog tsuas yog txhim kho cov khoom zoo thiab sib xws tab sis kuj ua kom cov khoom siv tau zoo tshaj plaws nyob rau hauv kev ua haujlwm nyuaj, muab kev txhawb zog thiab txhim khu kev qha rau siab -kev tsim khoom thiab kev tsim vaj tsev.
