Kev tsim cov txheej txheej insulating tsis yog ib qho teeb meem ntawm kev sib txuas ntawm cov khoom sib txuas, tab sis ib qho kev tsim vaj tsev ua haujlwm raws li kev nyab xeeb hluav taws xob, kev hloov pauv ib puag ncig, kev ua tau zoo, thiab cov hom phiaj kev loj hlob. Nws lub tswv yim tsim ua ke nrog kev txawj ntse ntawm ntau yam kev qhuab qhia xws li cov ntaub ntawv science, dielectric physics, nto engineering, thiab ntsuab tsim, aiming kom ua tiav kev tswj hwm los ntawm cov qauv molecular mus rau macroscopic zog, muab kev ntseeg siab, ruaj khov, thiab kev tiv thaiv hluav taws xob zoo rau cov khoom siv hluav taws xob nyob rau hauv ntau yam kev ua haujlwm nyuaj.
Functional orientation yog lub hauv paus pib taw qhia rau insulating txheej tsim. Cov neeg tsim qauv yuav tsum xub qhia meej txog daim ntawv thov scenario thiab kev ua tau zoo ntawm cov txheej txheem, xws li qib voltage, kev khiav hauj lwm kub, ambient humidity, tshuaj nruab nrab kev sib cuag, thiab mechanical stress type. Raws li qhov no, qhov tsim nyog cov khoom siv matrix raug xaiv - epoxy resin, vim nws muaj zog adhesion thiab zoo dielectric zog, feem ntau yog siv nyob rau hauv hnyav hluav taws xob ib puag ncig; silicone resin muaj qhov ua tau zoo thaum tshav kub kub thiab huab cua tsis kam, haum rau siab - kub thiab sab nraum zoov; polyurethane muaj qhov zoo ntawm kev ua kom yooj yim thiab ua haujlwm tsis zoo. Los ntawm kev tsim qauv molecular thiab kev hloov pauv copolymerization, dielectric tas li, dielectric poob, thiab lub zog tawg tuaj yeem ua kom zoo dua thaum tuav cov yeeb yaj kiab- tsim cov khoom, ua rau cov txheej txheem kom muaj kev ruaj ntseg nyob rau hauv lub hom phiaj hluav taws xob thiab ntau zaus.
Kev xav hauv lub cev qhia txog kev sib koom ua ke ntawm cov txheej txheej nrog cov txheej txheem, txheej txheem, thiab kev siv ib puag ncig. Qhov zoo ntawm interfacial bonding yog qhov tseem ceeb rau lub sij hawm ntev - kev cia siab ntawm cov txheej. Tus tsim yuav tsum xav txog lub substrate nto zog, roughness, thiab pretreatment txheej txheem. Los ntawm kev qhia cov neeg ua haujlwm sib txuas lossis ua kom zoo dua cov khoom ntub dej, lub cev muaj zog adsorption thiab tshuaj sib txuas tuaj yeem tsim tau, inhibiting kev nthuav tawm ntawm ib nrab tawm ntawm qhov cuam tshuam. Nyob rau tib lub sijhawm, cov viscosity, leveling zog, thiab curing kinetics ntawm txheej yuav tsum tau sib phim nrog rau daim ntawv thov txoj kev (immersion, spraying, txhuam, los yog electrophoresis) kom zoo ib yam kev pab them nqi thiab controllable thickness nyob rau hauv complex lug lossis loj - cheeb tsam coatings, tsis txhob pinholes, sagging, thiab defect accumulation.
Environmental adaptability thiab durability tsim tau nce los ua qhov tseem ceeb. Tau ntsib cov teeb meem xws li cov av noo, tshuaj tsuag ntsev, roj, pwm, thiab tshuaj lom neeg corrosion, feem ntau siv cov ntawv sib xyaw ua ke-xws li mica, iav fiber, los yog ceramic fillers los tsim "cov nyhuv maze," ncua txoj kev tawg thiab txhim kho corona tiv thaiv thiab kev laus tiv thaiv. Ntxiv UV-resistant, tiv thaiv-mildew, thiab qis-hygroscopic additives ua rau muaj kev ruaj ntseg nyob rau sab nraum zoov thiab dej hiav txwv. Thaum tshav kub kub kuj tseem tsom thiab txhim kho los ntawm kev xaiv cov resin thiab muab tub lim ua ke kom ua tau raws li qhov ntev - lub sijhawm ua haujlwm ntawm Chav B mus rau Chav H thiab txawm tias kub dua.
Cov tswv yim ntsuab thiab ruaj khov yog qhov muaj feem cuam tshuam txog kev tsim qauv. Ib txwm hnyav-raws li txheej txheej yog txwv los ntawm volatile organic compounds (VOC) emissions, ua hnyav-dawb, siab-khoom, thiab dej-raws li kev tshawb fawb hotspot. Cov qauv tsim yuav tsum sib npaug ntawm ib puag ncig kev phooj ywg thiab kev ua haujlwm, txo qhov cuam tshuam ib puag ncig thoob plaws lub neej tag nrho los ntawm kev ua kom zoo ntawm cov dej emulsification cov txheej txheem, hloov cov -cov tshuaj tua kab mob toxicity, thiab kev qhia txog bio-raws li raw khoom. Nyob rau tib lub sijhawm, txuas ntxiv cov txheej txheej txee lub neej thiab rov ua dua tshiab kuj raug txiav txim siab hauv kev tsim los txhawb txoj kev loj hlob ntawm kev lag luam ncig.
Kev sib koom ua ke ntawm kev ntseeg siab thiab kev tsim khoom yog qhov lav rau kev tsim qauv. Los ntawm kev ntsuam xyuas kev loj hlob nrog rau me me - nplai, pilot- nplai, thiab kev txheeb xyuas kev tsim khoom, kev ruaj ntseg ntawm kev tsim nyob rau hauv cov khoom sib txawv thiab cov txheej txheem raug lees paub. Kev sim ceev txoj hauv kev rau cov yam ntxwv tseem ceeb tau tsim, muab cov ntaub ntawv txhawb nqa rau kev tsim qauv. Kev taw qhia ntawm cov qauv kev simulation thiab kev ua haujlwm twv ua ntej tso cai rau kev kwv yees ntawm dielectric spectra, thermal conductivity, thiab kev laus tus cwj pwm thaum lub sij hawm tsim, ua kom luv R & D voj voog thiab txo qhov kev sim - thiab - cov nqi yuam kev.
Zuag qhia tag nrho, kev tsim lub tswv yim ntawm cov txheej txheej insulating yog coj los ntawm cov kev xav tau ntawm kev ua haujlwm, kev ua haujlwm sib txuam thiab kev sib koom ua ke ntau yam raws li txoj hauv kev kom ntseeg tau tias hluav taws xob muaj kev nyab xeeb thiab kav ntev thaum tseem xav txog kev ua phooj ywg ib puag ncig thiab kev tsim khoom. Qhov kev xav tob tob no yog tsav cov txheej txheem insulating los ntawm kev tiv thaiv kev tiv thaiv mus rau kev ua haujlwm zoo, tsim kom muaj kev cuam tshuam rau kev ua haujlwm nyab xeeb thiab txhim khu kev qha ntawm high - khoom siv hluav taws xob kawg thiab kev lag luam hluav taws xob tshiab.
