Tsamba la NOMEXndi pepala lopangidwa ndi zonunkhira za amide polymer insulating yokhala ndi zida zapamwamba zamakina, kusinthasintha komanso mphamvu zamagetsi zamagetsi, zomwe zimatha kukhalabe ndi mawonekedwe ake ngakhale kutentha kwambiri, komanso kugwiritsidwa ntchito kwambiri pamakina opangira magetsi, ma transfoma, zida zamagetsi, zamagetsi zamagetsi ndi zida zapakhomo.
Pali zabwino 8 za pepala la Nomex monga pansipa:
1. Mphamvu ya dielectric yobadwa nayo
The calendered Nomex insulating pepala mankhwala akhoza kupirira yochepa voteji kumunda mphamvu ya 18 ~ 40KV/mm, popanda mankhwala ndi varnish ndi utomoni.Chifukwa cha kuchepa kwa dielectric kwa zinthu za NOMEX, zimapangitsa kuti magetsi azikhala pakati pa kusungunula ndi kuzizira kwambiri.
2. Kulimba kwamakina
Pambuyo pa kalendala, pepala lotetezera la NOMEX limakhala lamphamvu kwambiri, ndipo limakhala ndi kusungunuka bwino, kukana misozi ndi kukana abrasion.Ndipo zinthu zoonda nthawi zonse zimakhala zosinthika.
3. Kukhazikika kwa kutentha
Mapepala otsekera a NOMEX ali ndi chilolezo cha UL kalasi ya kutentha kwa 220 ° C, zomwe zikutanthauza kuti imatha kugwira ntchito bwino kwa zaka zoposa 10 ngakhale itayikidwa mosalekeza pa 220 ° C.
4. Kugwirizana kwa Chemical
Pepala lotsekera la NOMEX silimakhudzidwa ndi zosungunulira zambiri, ndipo limakhala ndi kukana kwambiri kwa asidi ndi dzimbiri la alkali.Zimagwirizana mosavuta ndi ma varnish onse, zomatira, madzi a transformer, mafuta odzola ndi ozizira.Kuonjezera apo, mapepala otetezera a NOMEX sangawonongeke ndi tizilombo, bowa ndi nkhungu.
5. Kuchita kwa kutentha kochepa
Pansi pa kuwira kwa nayitrogeni (77K), mphamvu yamphamvu ya NOMEX insulating paper T410, NOMEX993 ndi 994 zonse zimaposa mtengo wa mphamvu kutentha kutentha.
6. Osamva chinyezi
Pamene NOMEX insulating paper ili ndi chinyezi cha 95%, mphamvu yake ya dielectric ndi 90% ya iyo mumkhalidwe wouma, ndipo panthawi imodzimodziyo, zinthu zambiri zamakina zimakhala bwino.
7. Kukana kwa radiation
Ngakhale mphamvu ya ma radiation ya ionizing ifika 800 megarads (8 megagrays), pepala lotsekera la NOMEX silimakhudzidwa, ndipo pambuyo pa ma radiation a 8, limasungabe makina ake ndi magetsi.
8. Zopanda poizoni komanso zoyaka moto
Pepala lotsekera la NOMEX silipanga zoopsa zilizonse zodziwika kwa anthu kapena nyama.Mapepala oteteza NOMEX samasungunuka mumlengalenga ndipo samathandizira kuyaka.Komanso, kuchepetsa kwake kwa oxygen index (LOI) pa 220 ° C ndi yaikulu kuposa 20.8 (nthawi zambiri kuyaka kofunikira kwa mpweya wopanda kanthu) mtengo), kotero sichidzawotcha.Pepala la Nomex insulating limakwaniritsa zofunikira zokana moto zomwe zafotokozedwa ndi UL94V-0.
Kwenikweni, banja la pepala la Nomex limaphatikizapo mitundu yosiyanasiyana, monga pepala lodziwika kwambiriNomex 410, ndiye Nomex 411, Nomex 414, Nomex 416, Nomex 464. Tidzakambirana Zambiri za mitundu yosiyanasiyana munkhani yotsatira.
