Urupapuro rwa NOMEXni sintetike ya aromatic amide polymer yerekana impapuro zifite imiterere yubukanishi buhanitse, ubworoherane nibintu byiza byamashanyarazi, bishobora kugumana imiterere yabyo ndetse no mubushyuhe bwinshi, kandi bikoreshwa cyane mumashini itanga amashanyarazi, transformateur, ibikoresho byamashanyarazi, ibikoresho bya elegitoroniki nibikoresho byo murugo.
Hano hari ibyiza 8 byimpapuro za Nomex nkuko bikurikira:
1. Imbaraga za dielectric
Ikirangantego cya Nomex gikingira impapuro zirashobora kwihanganira imbaraga zumwanya muto wa voltage yumuriro wa 18 ~ 40KV / mm, utabanje kuvurwa na varish na resin.Bitewe na dielectric idahoraho yibicuruzwa bya NOMEX, bituma umurima wamashanyarazi uri hagati yubukonje no gukonjesha byinshi.
2. Gukomera kwa mashini
Nyuma ya kalendari, impapuro zo kubika NOMEX zirakomeye rwose, kandi zifite ubuhanga bworoshye, kurwanya amarira no kurwanya abrasion.Kandi ibicuruzwa byoroheje bihora byoroshye.
3. Guhagarara neza
Urupapuro rwa NOMEX rukora ibyemezo bya UL icyiciro cy'ubushyuhe bwa 220 ° C, bivuze ko rushobora gukomeza gukora neza mumyaka irenga 10 nubwo rwaba rushyizwe kuri 220 ° C.
4. Guhuza imiti
Impapuro za NOMEX zidafite ingaruka ahanini kumashanyarazi, kandi zigaragaza uburyo bwiza bwo kurwanya aside na alkali.Irashobora guhuzwa byoroshye na langi zose, ibifatika, amavuta ya transformateur, amavuta na coolant.Byongeye kandi, impapuro za NOMEX ntizishobora kwangizwa nudukoko, ibihumyo.
5. Ubushyuhe buke
Munsi ya azote (77K), imbaraga zingana za NOMEX impapuro zikora T410, NOMEX993 na 994 zose zirenga agaciro k'ubushyuhe bwicyumba.
6. Ntabwo yunvikana nubushuhe
Iyo NOMEX yerekana impapuro zifite ubushyuhe bugereranije bwa 95%, imbaraga za dielectric ni 90% yibyo byumye rwose, kandi mugihe kimwe, ibintu byinshi byubukanishi biratera imbere.
7. Kurwanya imirase
Nubwo ubukana bwimirasire ya ionizing bugera kuri megarade 800 (megagra 8), impapuro zo kubika NOMEX ntizigira ingaruka, kandi nyuma yimiti 8 yimirasire, iracyakomeza imiterere yubukanishi namashanyarazi.
8. Ntabwo ari uburozi kandi bugurumana
NOMEX impapuro zitanga umusaruro ntizitanga uburozi buzwi kubantu cyangwa inyamaswa.Urupapuro rwa NOMEX ntirushonga mu kirere kandi ntirushyigikira gutwikwa.Byongeye kandi, igipimo cyacyo cya ogisijeni (LOI) kuri 220 ° C kirenze 20.8 (muri rusange gutwika kunegura umwuka wubusa)), ntabwo rero bizashya.Nomex yerekana impapuro zujuje ibyangombwa byo kurwanya flame byagenwe na UL94V-0.
Mubyukuri, umuryango wa Nomex impapuro zirimo ubwoko butandukanye, nkimpapuro zizwi cyaneNomex 410, hanyuma Nomex 411, Nomex 414, Nomex 416, Nomex 464. Tuzaganira kubintu byinshi biranga ubwoko butandukanye muriingingo ikurikira.
