Hauv cov khoom siv hluav taws xob thiab hluav taws xob niaj hnub no, kev ua haujlwm rwb thaiv tsev yog ib qho tseem ceeb ntawm kev txiav txim siab seb cov khoom puas tuaj yeem ua haujlwm zoo, ruaj khov, thiab ntev ntev. Insulating coatings, as high-performance coating materials made with polymer resins as a matrix, supplemented with functional fillers, additives, and solvents, effectively block current leakage, suppress partial discharge, and resist environmental corrosion by forming a continuous and dense protective film on conductors, cores, coils, and other critical components. Lawv tau dhau los ua cov khoom siv tseem ceeb hauv lub zog, hluav taws xob, hluav taws xob tshiab, thiab kev lag luam tsheb thauj mus los.
Los ntawm cov qauv kev xav, cov txheej txheem insulating feem ntau muaj cov khoom siv cob, kho tus neeg saib xyuas, pigments thiab muab tub lim, additives, thiab diluents. Resin matrix txiav txim siab qhov yooj yim insulating zog thiab adhesion ntawm txheej. Cov hom muaj xws li alkyd resins, epoxy resins, polyurethanes, silicones, thiab polyimides, txhua tus muaj nws tus kheej zoo nyob rau hauv tshav kub tsis kam, yooj, tshuaj corrosion kuj, thiab hluav taws xob khoom. Curing agents thiab additives tswj tus cwj pwm curing thiab zaj duab xis zoo ntawm txheej; fillers (xws li mica, iav fiber, thiab alumina) tuaj yeem txhim kho cov cua sov thiab lub zog txhua yam; thiab pigments qee zaum ua haujlwm rau ob qho tib si xim thiab cov khoom siv rwb thaiv tsev.
Lub hauv paus kev ua tau zoo ntawm insulating txheej yog nyob rau hauv lawv cov hluav taws xob zoo rwb thaiv tsev, zoo kub tsis kam, thiab ib puag ncig kam rau ua. Lawv qhov ntim resistivity feem ntau yog nyob rau hauv thaj tsam ntawm 10¹² txog 10¹⁶ Ω·cm, thiab lawv lub zog dielectric tuaj yeem ncav cuag kaum tawm kilovolts ib millimeter, tswj xyuas qhov kev ruaj ntseg rwb thaiv tsev nyob rau hauv siab -voltage ib puag ncig. Cov qib kub tiv thaiv npog B (130 degree) txog H (180 degree) thiab siab dua, ua tau raws li qhov ntev - lub sijhawm ua haujlwm ntawm cov motors, transformers, reactors, thiab lwm yam khoom siv nyob rau hauv siab - kub. Kev tiv thaiv noo noo, mildew tsis kam, ntsev tsuag tshuaj tiv thaiv, thiab roj kuj ua kom lub txheej ruaj khov nyob rau hauv cov av noo, kub, dej hiav txwv, thiab tshuaj lom neeg ib puag ncig, txuas ntxiv cov khoom siv tu lub voj voog.
Nyob rau ntawm daim ntawv thov, cov txheej txheej insulating yog dav siv rau impregnation thiab tiv thaiv nto ntawm lub cev muaj zog windings, tsim ib qho tseem ceeb insulating txheej thiab txhim kho lub winding thermal conductivity thiab ya raws. Nyob rau hauv transformers thiab reactors, lawv yog siv raws li interlayer thiab kawg rwb thaiv tsev txheej los txo qhov kev pheej hmoo ntawm ib nrab paug. Cov khoom siv fais fab thiab cov busbars kuj tuaj yeem raug coated los tiv thaiv arc hlawv thiab ib puag ncig muaj kuab lom. Hauv cov khoom siv hluav taws xob, lawv tau siv rau kev tiv thaiv Circuit Court board, tivthaiv encapsulation, thiab siab -frequency coil rwb thaiv tsev kom ntseeg tau cov teeb liab kev ncaj ncees thiab ntev- lub sij hawm cia siab. Nyob rau hauv lub zog tshiab, xws li cua turbines, photovoltaic inverters, thiab lub zog cia tshuab, siab - tshav kub- tiv taus thiab huab cua- resistant insulating coatings txhim khu ib puag ncig adaptability thiab kev pab cuam lub neej ntawm cov khoom sab nraum zoov.
Cov txheej txheem thov cuam tshuam cuam tshuam rau txheej txheej. Cov txheej txheem feem ntau suav nrog impregnation, txau, txhuam, thiab electrophoresis, thiab cov qauv tsim nyog yuav tsum raug xaiv raws li cov qauv ua haujlwm thiab kev ua haujlwm. Nto tu thiab preheating ua ntej daim ntawv thov pab txhim kho adhesion; tswj txheej thickness thiab uniformity tsis txhob pinholes thiab localized tsis muaj zog cov ntsiab lus; kho tej yam kev mob (kub, lub sij hawm, thiab cua) yuav tsum nruj me ntsis raws li lub formulation specifications kom paub meej txaus cross-txuas thiab kev ua tau zoo.
Raws li cov khoom siv hluav taws xob hloov mus rau lub zog siab dua, kev ua haujlwm me me, thiab kev ua neej ntev dua, cov txheej txheej insulating tau tsim los ntawm kev kub siab dua, qis dielectric poob, cov kuab tshuaj zoo ib puag ncig - cov khoom tsis pub dawb, thiab kho sai dua. Kev nce qib ntawm cov kuab tshuaj-dawb thiab dej-raws li cov tshuab tsis tsuas yog ua tau raws li cov txheej txheem rwb thaiv tsev nruj tab sis kuj tseem txo qis cov pa taws tsis zoo ntawm cov organic compound emissions, ua raws li cov qauv ntawm kev tsim ntsuab.
Nyob rau hauv cov ntsiab lus, insulating txheej, nrog hluav taws xob rwb thaiv tsev raws li lawv cov tub ntxhais, kuj muaj tshav kub tsis kam, tiv thaiv, thiab txheej txheem adaptability. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev lag luam ntawm cov khoom siv hluav taws xob, thiab lawv cov thev naus laus zis thiab kev nthuav dav yuav txuas ntxiv los txhawb kev txhim kho txhim khu kev qha ntawm siab -kev tsim khoom thiab kev tsim hluav taws xob.
