Tus nqi ntawm epoxy resin castables stems tsis tsuas yog los ntawm lawv cov kev ua tau zoo tshaj plaws, tab sis kuj los ntawm lawv cov kev siv suab hauv kev tshawb fawb. Daim ntawv thov kev lag luam muaj kev vam meej yuav tsum tau kaw - lub voj voog uas suav nrog kev npaj cov khoom, kev tswj cov txheej txheem, cov khoom sib txuam, thiab kev tshuaj xyuas zoo. Qhov no ua kom muaj kev tswj xyuas meej ntawm txhua kauj ruam los ntawm cov khoom siv raw mus rau cov khoom tiav, ua kom zoo tshaj plaws thiab txo qhov tsis xws luag.
Lub hauv paus ntawm kev npaj theem yog meej formulation thiab uniform dispersion. Tom qab xaiv cov matrix resin, curing agent, functional fillers, thiab additives raws li daim ntawv thov, lawv yuav tsum tau hnyav raws li qhov kev faib ua feem raws li qhov kub thiab txias tsis tu ncua thiab sib xyaw ua ke siv high - ceev dispersion los yog planetary mixing khoom. Txhawm rau kom tsis txhob muaj huab cua npuas thiab agglomeration, lub tshuab nqus tsev sib xyaw feem ntau yog siv, tshem tawm cov huab cua thiab volatiles nyob rau hauv qhov tsis zoo siab los tsim kom muaj kev ruaj ntseg ntawm cov muab tub lim thiab cov resin matrix. Viscosity thiab kub tswj yog ib qho tseem ceeb heev nyob rau theem no, ncaj qha cuam tshuam lub fluidity thiab wettability ntawm tom ntej casting.
Kev tsim kho txoj kev sib txawv nyob ntawm seb cov khoom zoo li cas thiab kev ua haujlwm. Rau cov khoom uas muaj cov txheej txheem nyuaj lossis cov kab noj hniav me me, tsawg- cov kua viscosity castables raug pom zoo, siv lub tshuab nqus tsev siab los yog qis qis ntawm atmospheric siab kom ntseeg tau tias cov khoom nkag mus rau txhua lub ces kaum thiab ua kom tsis tu ncua, tsis xws luag -dawb solidification txheej. Rau ntsug lossis loj- cheeb tsam kev tsim kho, thixotropic muab tshuaj txhuam-zoo li castables tuaj yeem siv los txo qis qis thiab txhim kho ntug. Yog tias tsim nyog, muab cov khoom sib dhos lossis ntu ntu tuaj yeem ua haujlwm los xyuas kom meej qhov tseeb. Thaum lub sij hawm casting, qhov ruaj khov ambient kub thiab av noo yuav tsum tau tswj kom tsis txhob muaj qhov txawv txav tshwm sim los ntawm kev hloov pauv sab nraud.
Cov txheej txheem kho yog qhov tseem ceeb rau kev ua tiav kev hloov pauv. Rau chav -kub kho, lub sij hawm txaus yuav tsum tau tso cai rau ua tiav cov tshuaj tiv thaiv, zam kev cuam tshuam thiab kub hloov pauv sai. Rau cov cua sov- kho, ua ntej- teeb tsa kub nce nkhaus yuav tsum tau ua raws li kom ntseeg tau tias muaj qhov sib txawv ntawm qhov kub thiab txias thiab tiv thaiv kev ntxhov siab tawg los ntawm kev kub kub hauv zos. Rau qhov loj lossis tuab - cov khoom siv phab ntsa, cov txheej txheem cua sov thiab cov rwb thaiv tsev tuaj yeem raug coj los ua kom sib npaug ntawm qhov kev kho kom zoo thiab qhov ruaj khov.
Kev tshuaj xyuas zoo yog ua nyob rau hauv tag nrho cov txheej txheem. Ua ntej casting, xyuas qhov huv thiab sealing ntawm pwm. Thaum lub sij hawm casting, saib xyuas qhov ntws thiab cua npuas. Tom qab kho, xyuas kom tseeb tias cov khoom ua tau raws li qhov yuav tsum tau ua los ntawm kev tshuaj xyuas qhov muag, hla -sectional analysis, thiab kev kuaj hluav taws xob thiab khoom siv kho tshuab. Rau cov ntawv thov tseem ceeb, tsis yog- cov txheej txheem ntsuas kev puas tsuaj tuaj yeem raug qhia los ntsuas qhov tsis xws luag sab hauv thiab ua kom ntseeg tau ntev- lub sijhawm ua haujlwm.
Hauv cov ntsiab lus, daim ntawv thov txheej txheem ntawm epoxy resin castables yog kev sib koom ua ke ntawm kev tsim qauv, kev npaj meej, kev ua tiav, thiab kev tswj kom zoo. Tsuas yog los ntawm kev sib koom tes thiab kev tswj xyuas meej ntawm txhua theem tuaj yeem ua rau nws txoj kev rwb thaiv tsev, kev tiv thaiv, thiab kev txhim kho cov txheej txheem kom tau txais txiaj ntsig zoo, muab kev ruaj khov thiab ruaj khov lav rau siab -kev tsim khoom thiab kev tsim kho.
