2. Enamelled Wire Taw qhia thiab kev siv
Txawm hais tias tau piav qhia tias "enameled", enameled hlau tsis yog, qhov tseeb, coated nrog ib txheej ntawm cov xim enamel lossis nrog vitreous enamel ua los ntawm fused iav hmoov. Niaj hnub nimno hlau nplaum hlau feem ntau siv ib mus rau plaub txheej (nyob rau hauv cov ntaub ntawv ntawm quad-film hom hlau) ntawm polymer zaj duab xis rwb thaiv tsev, feem ntau ntawm ob sib txawv compositions, muab ib tug tawv, nruam insulating txheej. Magnet hlau insulating zaj duab xis siv (nyob rau hauv kev txiav txim ntawm qhov kub ntau ntau) polyvinyl formal (Formar), polyurethane, polyimide, polyamide, polyster,polyester-polyimide, polyamide-polyimide (los yog amide-imide), thiab polyimide. Polyimide insulated hlau nplaum hlau muaj peev xwm ua haujlwm ntawm txog 250 ° C. Cov rwb thaiv tsev ntawm cov hlau nplaum tuab tuab los yog cov hlau nplaum hlau feem ntau yog augmented los ntawm kev qhwv nws nrog lub siab kub polyimide los yog fiberglass daim kab xev, thiab ua tiav windings feem ntau nqus impregnated nrog ib tug insulating kua roj vanish los txhim kho rwb thaiv tsev lub zog thiab lub sij hawm ntev kev cia siab ntawm lub winding.
Kev txhawb nqa tus kheej yog qhov txhab nrog hlau coated nrog tsawg kawg yog ob txheej, sab nraud yog cov thermoplastic uas khi cov lem ua ke thaum rhuab.
Lwm hom kev rwb thaiv tsev xws li fiberglass yarn nrog cov kua roj vanish, aramid ntawv, kraft ntawv, mica, thiab polyester zaj duab xis kuj tau dav siv thoob ntiaj teb rau ntau yam kev siv xws li transformers thiab reactors. Nyob rau hauv lub suab sector, ib tug hlau ntawm nyiaj siv, thiab ntau yam insulators, xws li paj rwb (qee zaum permeated nrog ib co coagulating tus neeg saib xyuas / thickener, xws li beeswax) thiab polytetrafluoroethylene (PTFE) tuaj yeem pom. Cov ntaub ntawv rwb thaiv tsev laus suav nrog paj rwb, ntawv, lossis lo lo ntxhuav, tab sis cov no tsuas yog siv tau rau cov ntawv thov kub (txog 105 ° C).
Rau kev yooj yim ntawm kev tsim khoom, qee qhov qis-kub-qib hlau nplaum hlau muaj rwb thaiv tsev uas tuaj yeem raug tshem tawm los ntawm tshav kub ntawm soldering. Qhov no txhais tau hais tias kev sib txuas hluav taws xob ntawm qhov kawg tuaj yeem ua tau yam tsis muaj stripping tawm ntawm lub rwb thaiv tsev ua ntej.
