Hauv high-kev tsim khoom thiab kev tsim kho vaj tse, kev ntseeg siab ntawm cov khoom siv feem ntau txiav txim siab lub neej ntawm cov khoom siv thiab kev nyab xeeb engineering. Epoxy resin castables, cov txheej txheem sib xyaw ua ke raws li epoxy resin, ua ke nrog cov neeg ua haujlwm kho thiab cov khoom ua haujlwm, tau dhau los ua cov khoom tseem ceeb rau kev ua haujlwm ruaj khov thiab ntev ntev - kev tiv thaiv hauv kev lag luam xws li lub cev muaj zog, hluav taws xob, hluav taws xob, thiab cov tshuab precision vim lawv qhov zoo heev adhesion, rwb thaiv tsev, thiab ib puag ncig tiv thaiv.
Los ntawm cov txheej txheem kev xav, epoxy resin castables, los ntawm cov txheej txheem xws li lub tshuab nqus tsev sib xyaw thiab siab -kub curing, tuaj yeem tsim qhov ntom ntom, tsis yog - ntxeem tau cov qauv. Lawv cov ncej- kho shrinkage tsawg (feem ntau<1%), effectively avoiding interfacial delamination caused by deformation in traditional potting materials. Simultaneously, the cross-linked structure of the resin molecular chains endows the material with high mechanical strength (tensile strength can reach over 50 MPa) and impact toughness, resisting stress damage under complex conditions such as vibration and thermal cycling. In terms of electrical performance, their volume resistivity exceeds 10¹⁴ Ω·cm, and their dielectric loss factor is below 0.02, ensuring stable insulation performance of high-voltage equipment and reducing the risk of partial discharge. The expansion of application scenarios further highlights its value. In the new energy field, the use of this material in the casting of wind turbine stators and photovoltaic inverter modules can isolate them from salt spray and moisture corrosion, extending the service life of outdoor equipment. In the power industry, the casting of transformer and reactor coils can optimize heat dissipation paths and improve overload capacity. In the field of electronic devices, the packaging of sensors and IGBT modules relies on its precise dimensional stability and electromagnetic shielding effectiveness. Furthermore, for special needs, by adjusting the filler ratio (such as adding alumina and silicon micropowder), functional products with thermal conductivity (>1.5W / (m·K)) thiab nplaim hluav taws (UL94 V-0 ntsuam xyuas) tuaj yeem hloov kho, hloov mus rau cov xwm txheej tshwm sim xws li 5G hauv paus chaw nres tsheb thiab kev tsheb ciav hlau.
Raws li cov khoom lag luam tsim tawm mus rau lub zog siab, miniaturization, thiab lub neej ntev, epoxy resin casting cov ntaub ntawv tau txuas ntxiv thawb kev ua haujlwm ciam teb. Los ntawm kev tsim qauv molecular thiab kev ua kom zoo dua, kev nce qib hauv qis -kub curing thiab qis - viscosity kev tsim kho tau txo qis qhov nyuaj ntawm cov khoom loj loj. Raws li tus neeg nqa khoom tseem ceeb txuas cov ntaub ntawv kev tshawb fawb thiab kev tsim vaj tsev, nws tsis yog tsuas yog "cov cuab yeej pom tsis pom" los txhim kho cov cuab yeej kev ntseeg siab, tab sis kuj yog ib qho kev txhawb nqa tseem ceeb rau kev txhawb nqa kev txhim kho qib siab -kev tsim khoom kawg.
