Hauv qib siab - cov khoom siv tsim khoom kawg thiab cov chaw tsim kho tseem ceeb, qib kev ua haujlwm ntawm cov ntaub ntawv ncaj qha txiav txim siab txog kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv. Epoxy resin castables, nrog rau lawv cov khoom muaj txiaj ntsig zoo tshaj -dimensional, tau dhau los ua cov ntaub ntawv tseem ceeb rau kev ua tiav cov txheej txheem solidification, rwb thaiv tsev tiv thaiv, thiab kev sib koom ua ke hauv kev lag luam xws li lub cev muaj zog, hluav taws xob, hluav taws xob, thiab lub zog tshiab. Lawv cov txiaj ntsig kev ua tau zoo yog los ntawm kev sib koom ua ke ntawm cov resin matrix, kev kho qhov system, thiab cov khoom ua haujlwm ua haujlwm, suav nrog txhua yam, hluav taws xob, thermal, thiab ib puag ncig kev hloov pauv.
Hais txog cov khoom siv kho tshuab, tom qab kho, epoxy resin castables tsim ib qhov ntom ntom peb -dim ntoo khaub lig- txuas lub network, muaj zog tensile thiab flexural zog thaum tuav cov toughness nruab nrab. Qhov no zoo tiv thaiv txhua yam kev vibration, cuam tshuam loads, thiab kev ntxhov siab hloov pauv los ntawm thermal expansion thiab contraction, tiv thaiv brittle puas. Qhov kev sib xyaw ua ke ntawm rigidity thiab yooj yooj yim ua rau lawv ruaj khov hauv cov khoom siv xws li transformers thiab reactors raug rau ntev - lub sij hawm dynamic loads.
Kev ua haujlwm hluav taws xob yog ib qho ntawm nws qhov zoo tshaj plaws. Cov khoom siv muaj qhov ntim siab heev, tsis tshua muaj dielectric tsis tu ncua thiab dielectric poob, thiab ruaj khov dielectric zog. Nws tuaj yeem cuam tshuam cov dej xau tam sim no thiab ib feem ntawm qhov tshwm sim nyob rau hauv siab -voltage ib puag ncig, muab kev lav zoo rau kev tiv thaiv kev nyab xeeb ntawm lub zog thiab cov khoom siv hluav taws xob. Nws cov hluav taws xob rwb thaiv tsev zoo heev ua kom nws tswj tau qhov tseeb thiab ruaj khov ntawm cov teeb liab kis tau tus mob nyob rau lub sijhawm ntev hauv kev ntim khoom ntawm cov khoom siv hluav taws xob precision.
Nyob rau hauv cov nqe lus ntawm thermal zog, epoxy resin castings muaj zoo seem thermal stability thiab ib tug nruab nrab kub kuj ntsuas. Los ntawm kev qhia cov thermal conductivity siab, thermal conductivity tuaj yeem txhim kho ntxiv, tso cai rau cov cua kub sai sai los ntawm cov khoom siv hluav taws xob thiab lwm yam cua sov- tsim cov khoom siv, ua kom zoo dua cov cua kub dissipation txoj hauv kev, thiab txhim kho cov khoom siv hluav taws xob ceev thiab kev ua haujlwm ruaj khov.
Environmental adaptability kuj tseem ceeb heev. Cov khoom no nthuav tawm muaj zog tiv thaiv cov roj, kua qaub thiab alkali daws, thiab ntau yam kev lag luam gases, thiab tiv thaiv kev nkag mus ntawm noo noo, ntsev tsuag, thiab cov kab mob, ua rau nws tsim nyog rau hnyav marine, tshuaj, thiab sab nraum zoov ib puag ncig. Nrog rau kev hloov kho, nws tseem tuaj yeem ua tiav cov nplaim hluav taws kub, UV tsis kam, thiab huab cua tsis kam, ua tau raws li qhov yuav tsum tau ua ntawm lub neej ntev thiab kev nyab xeeb siab hauv cov teb xws li kev tsheb ciav hlau thiab lub zog tshiab.
Tsis tas li ntawd, epoxy resin castings muaj tsawg curing shrinkage thiab zoo seem raug tuav, txo kev sib dhos sib txawv los ntawm deformation. Ua ke nrog lub tshuab nqus tsev sib xyaw thiab cov txheej txheem casting precision, siab - cov qauv zoo tsis muaj qhov hws thiab cov kab nrib pleb tuaj yeem tau txais, txhim kho cov khoom sib xws thiab kev ntseeg tau zoo.
Zuag qhia tag nrho, qhov sib npaug thiab tsim kom muaj peev xwm ntawm epoxy resin castables nyob rau hauv cov ntsiab lus ntawm txhua yam, hluav taws xob, thermal thiab ib puag ncig cov khoom ua rau lawv yog ib qho tseem ceeb ntawm cov khoom siv txhawb kev nyab xeeb thiab kev ua haujlwm zoo ntawm kev lag luam niaj hnub, thiab lawv tau nthuav dav cov ciam teb ntawm siab -kawg daim ntawv thov los ntawm kev txuas ntxiv mus.
