Cov enamels yog cov varnishes coated rau ntawm qhov chaw ntawm tooj liab lossis alumina xov hlau thiab kho kom zoo nkauj los ua cov zaj duab xis rwb thaiv tsev hluav taws xob uas muaj qee yam zog kho tshuab, thermal resistant thiab tshuaj resistant zog. Cov hauv qab no suav nrog qee hom enamel ntawm Tianjin Ruiyuan.
Polyvinylformal
Polyvinylformal resin yog ib qho ntawm cov xim pleev xim qub tshaj plaws, hnub tim rov qab mus rau xyoo 1940. Feem ntau lub npe hu ua FORVAR (yav tas los tsim los ntawm Monsanto lub tuam txhab thiab tam sim no tsim los ntawm Chisso), nws yog cov khoom polycondensation ntawm formaldehyde thiab hydrolyzed polyvinyl acetate. PVF yog mos mos thiab muaj kev tiv thaiv cov kuab tshuaj tsis zoo. Txawm li cas los xij, nws tuaj yeem ua tiav kev ua tau zoo dua thaum siv ua ke nrog phenolic resin, melamine formaldehyde resin lossis polyisocyanate resin.
Polyurethane
Polyurethane tau tsim tawm hauv lub teb chaws Yelemees thaum xyoo 1940s. Chiv thawj, qib kub yog nruab nrab ntawm 105 ° C thiab 130 ° C, tab sis tam sim no nws tau txhim kho mus rau 180 ℃, thiab ua tau zoo dua. Nws yog siv dav hauv cov khoom siv hluav taws xob qis xws li cov kauj vuam precision, lub cev muaj zog, cov twj paj nruag, cov khoom siv hauv tsev, thiab lwm yam vim nws cov xim zoo heev, cov txheej txheem siab thiab kev sib txuas ncaj.
PU hlau tuaj yeem raug soldered yam tsis tau stripping lub txheej.
Polyamide
Kuj hu ua nylon, nws feem ntau siv ua topcoat thiab tuaj yeem txhim kho lubricating, lub cev thiab cov khoom siv kho tshuab ntawm PVF, PU thiab PE enamel. Polyamide tuaj yeem siv ua cov tshuaj ntawm cov fiber yooj yim lossis cov polymers tawg. Cov khoom khov ntawm cov molecular ntawm cov polymer no tso cai rau cov tshuaj kom muaj viscosity siab dua ntawm cov khoom khov qis dua.
Polyester
Lub zog zoo, nplaum zaj duab xis xim, tiv taus hluav taws xob zoo heev, tiv taus tshuaj lom neeg, ruaj khov thermal thiab tiv taus cov kuab tshuaj; siv rau hauv kev sib txuas lus hluav taws xob teeb pom kev zoo, lub cev muaj zog submersible kaw, micro-generators, transformers tiv taus cua sov, contactors, electromagnetic valve. Cov polyester enamel yooj yim tshaj plaws yog cov khoom ua haujlwm ntawm terephthalic acid, glycerin thiab ethylene glycol uas yog cov khoom sib xyaw ua ke ntawm 155 ° C qib polyester enamel. (Thaum lub neej kub ntawm cov xim no tshaj 180, lwm yam khoom xws li kev poob siab kub ze rau 155 ° C, tshwj tsis yog tias qhov chaw tau coated nrog nylon).
Polyesterimide
Cov hlau nplaum polyesterimide uas siv tau yooj yim yog siv dav rau cov hlau nplaum rau cov relays, cov transformers me me, cov motors me me, cov contactors, cov ignition coils, cov magnetic coils thiab cov automotive coils. Cov txheej no tshwj xeeb tshaj yog haum rau cov motors hluav taws xob me me los txuas cov windings rau lub collector. Cov hlau nplaum coated muaj elasticity zoo nrog rau cov khoom dielectric thiab mechanical zoo. Nws muaj cov khoom siv tshuaj zoo heev, tiv taus cua sov zoo thiab tiv taus cov refrigerants.
Polyamide-imide
Cov hlau polyamide-imide enamels tuaj yeem siv ua ob txheej lossis ib txheej, tab sis ob qho kev xaiv muab cov khoom siv zoo heev, tiv taus tshuaj lom neeg, tiv taus cua sov siab, lub zog tensile siab thiab tiv taus qaug zog.
Polyimide
Qhov Ntsuas Kub: 240C
PI tau muag los ntawm DuPont hauv xyoo 1960. Nws yog cov txheej txheem organic kub siab tshaj plaws. Siv rau hauv daim ntawv ntawm cov kua qaub polyamic, hloov pauv nrog cua sov mus rau zaj duab xis tas mus li. Muaj kev ruaj khov thermal zoo heev, tiv taus hluav taws xob, tshuaj lom neeg thiab qhov kub cryogenic. Txiav qhov tob > 500 ℃.
Cov Enamel uas nplaum nws tus kheej
Nyob ntawm seb cov neeg siv khoom xav tau ntau yam khoom ntau npaum li cas, nws muaj cov yam ntxwv sib txawv thiab ntau yam kev siv. Tianjin Ruiyuan siv cov enamels uas sib txuas ua ke uas yog ua los ntawm epoxy, polyvinyl-butyral thiab polyamide siv los ua kom lub winding ruaj khov. Lawv feem ntau yog siv los txheej cov cuab yeej coils, lub suab coils, lub suab hais lus, lub cev muaj zog me me thiab cov sensors.
Txhua cov xov hlau nplaum tuaj yeem ua raws li qhov xav tau ntawm cov neeg siv khoom, Tianjin Ruiyuan, koj tus kws tshaj lij kev daws teeb meem hlau nplaum. Thov koj xav tiv tauj peb yog tias koj muaj lus nug.
