Mawaya a EPDM (Ethylene Propylene Diene Monomer) amagwiritsidwa ntchito kwambiri m'mafakitale, magalimoto, magetsi ndi zida zapanyumba chifukwa cha kukana kwawo kutentha kwambiri, kukana nyengo komanso magetsi. EPDM ndi mtundu wa zinthu zopangira mphira zokhala ndi unyolo wodzaza kwambiri, motero zimakana kutsekemera kwa okosijeni, ozoni ndi cheza cha ultraviolet, ndipo zimatha kugwira ntchito mokhazikika m'malo ovuta kwa nthawi yayitali. Tsopano tikusanthula magwiridwe antchito ndi magawo aMtengo wa EPDMs, makamaka mitundu iwiri yotchuka, UL3311 ndi UL3279 ndi ntchito yake yeniyeni ndi mfundo zazikulu zogwiritsira ntchito. Fakitale yathu imapanga mitundu yonse iwiriyi. Ngati mungafune kudziwa zambiri kapena kugula, chonde omasuka kulumikizana nafe.
Ubwino wapadera wa zida za EPDM
EPDM ndi mphira wopangidwa ndi copolymerized kuchokera ku ethylene, propylene, ndi ma diene monomers ochepa. Mapangidwe ake a mamolekyu ali ndi zomangira zocheperapo ziwiri, motero zikuwonetsa kukhazikika kwamankhwala komanso kusinthasintha kwachilengedwe. Poyerekeza ndi mphira wachilengedwe kapena mphira wina wopanda unsaturated, EPDM imawonetsa kuchita bwino kwambiri polimbana ndi kutentha, kuchepa-kutsika kwa kutentha, kukana chinyezi, kukana kwa UV, ndi kukana mankhwala.
-
Katundu Wamagetsi: Mphamvu zabwino kwambiri za dielectric ndi mphamvu ya voliyumu, yoyenera pamagetsi apakatikati mpaka apamwamba komanso kugwiritsa ntchito magetsi otsika.
-
Katundu Wamakina: Kusinthasintha kwakukulu, kukhazikika bwino komanso kukana abrasion, kusunga umphumphu ngakhale kupindika mobwerezabwereza.
-
Kusamvana Kwachilengedwe: Kusamvana ndi ozoni, kuwala kwa UV, asidi, alkalis, ndi zosungunulira zambiri, zomwe zili zoyenera kunja kapena{0}}zinyezi zambiri.

Kukhazikika kwamafuta: Kutentha kopitilira muyeso kopitilira, kumatha kupirira kutentha kwakanthawi kochepa popanda kufewetsa kapena kusweka.
-
Zina: Utsi wochepa ndi halogen-zaulere (zitsanzo zina), zimagwirizana ndi RoHS, ndizogwirizana ndi chilengedwe.
Zinthu izi zimapangaMtengo wa EPDMapamwamba kwambiri kuposa zipangizo zotchinjiriza wamba monga PVC, makamaka pa kutentha kapena nyengo yovuta.
Kufotokozera Mwatsatanetsatane Nambala Zachitsanzo za UL3311 ndi UL3279
Muzinthu zamawaya za EPDM, UL certification ndi kampani yomwe imatsogolera kuzinthu zotetezedwa komanso kusasinthasintha.UL3311ndiUL3279ndi zingwe ziwiri za batri zomwe zimagwiritsidwa ntchito kwambiri komanso zotsogola zamagalimoto, zomwe nthawi zambiri zimatsimikiziridwa limodzi kapena zimagwiritsidwa ntchito molingana.
UL3311
Amapangidwa kuti azingotha kusinthasintha- ma lead motor motor ndi mawaya amkati okhala ndi kutentha kwa madigiri 90 . Mogwirizana ndi miyezo ya UL ndi CSA, magetsi ovotera pa 600V. Zomangamanga zodziwika bwino zimaphatikizapo Class K (30 AWG fine strand) zopanda kapena zomata zamkuwa, zotchingira mapepala, ndi sheath yakunja ya EPDM. Kukula kwa makondakitala kumasiyanasiyana malinga ndi kukula kwa kondakita (nthawi zambiri 0.060-0.080 mainchesi pamakondakita opitilira 8 AWG), ndipo nthawi zambiri imakhala yosinthika, yosamva ma abrasion, komanso yosavuta kuvula. Kutentha nthawi zambiri kumakhala madigiri -50 kufika ku +90 digirii , yoyenera makina a batire, zingwe za solder, UPS, ndi mawaya amkati muzipangizo zapakhomo.
UL3279
Nthawi zambiri amaphatikizidwa ndi UL3311, yopereka kutentha kwapamwamba kwa madigiri 105. Komanso 600V, EPDM insulated, yoyenera kugwiritsa ntchito zomwe zimafuna kutentha kosalekeza kokwera pang'ono, monga ma lead lead kapena zolumikizira magetsi m'malo otentha kwambiri-. Mitundu iwiriyi ndi yofanana kwambiri, ndipo opanga ambiri amapereka zinthu zomwe zimakumana ndi UL3311/UL3279 nthawi imodzi, zomwe zimapereka kusinthasintha.
| Kondakitala | Kalasi K wopindika kwambiri wa mkuwa wopanda kanthu kapena malata-wopukutidwa (monga 6 AWG yokhala ndi zingwe 259 x 30) |
| Insulation | Thermosetting EPDM yokhala ndi mphamvu zabwino kwambiri za dielectric komanso peelability |
| Voteji | 600V |
| Moto retardant | Amadutsa FT1, FT2, VW-1 ndi mayeso ena |
| Zitsimikizo | UL, CRUUS, RoHS, nthawi zambiri ndi zero halogen njira |
Zochitika zofananira ndikugwiritsa ntchito
Waya wa EPDM umawala m'mafakitale ambiri chifukwa cha kusinthasintha kwake:
Amagwiritsidwa ntchito polumikizira mabatire agalimoto yamagetsi (EV), okwera-mahatchi othamanga kwambiri, ndi makina ochajira. Kusasunthika kwa asidi, kusagwedezeka kwake, komanso kutentha kwakukulu kumatsimikizira kudalirika kwa nthawi yayitali-.
Amagwiritsidwa ntchito ngati ma motor lead, ma transfoma, ma coil, ndi mawaya amkati pazida zamagetsi. Mitundu ya UL3311/3279 ndiyoyenera kwambiri-ma injini otentha kwambiri kapena zida zomwe zimafunikira kupindika pafupipafupi.
Zingwe zowotcherera, ma inverter a solar, zida zamagetsi zamagetsi, ndi makina a UPS. Kukaniza kwanyengo kwa EPDM kumapangitsa kuti ikhale yoyenera kuyika kwakunja kwa photovoltaic kapena magetsi amphepo.
Kutumiza kwamagetsi osinthika kwambiri m'mafakitale apanyanja, njanji, ndi makina omanga
M'mapulogalamu enieni-padziko lonse lapansi, opanga ambiri amapereka zinthu zoyambira 8 AWG mpaka 4/0 kapena zokulirapo, zomwe zimagwirizana ndi utali wanthawi zonse ndi mitundu (nthawi zambiri zofiira/zakuda), monga momwe zimakhalira ndi fakitale yathu.
Momwe mungasankhire njira yoyenera ndi njira zodzitetezera
-
Zofunikira za Kutentha: UL3311 pa digiri ya 90, UL3279 yokonda 105 digiri.
-
Kukula kwa Kondakitala: Kuwerengera kutengera katundu wapano (onani tebulo la AMPACITY); sankhani zigawo zazikulu -zopingasa (monga 2/0 AWG) za mafunde okwera kwambiri.
-
Zinthu Zachilengedwe: Ntchito zakunja zimafuna kutsindika pa chitetezo cha UV ndi kukana madzi; kutsimikizira kukana dzimbiri kwa malo okhudzana ndi mankhwala.
-
Kusinthasintha: Kulowera kwa Class K kumapereka ma radius abwino kwambiri opindika, oyenera zida zam'manja.
-
Zitsimikizo ndi Kutsata: Onetsetsani kuti nambala yolembera ya UL (mwachitsanzo, E352430) ndi satifiketi ya RoHS.
Pakuyika, tcherani khutu pakusankhidwa kwa chida chovulira cha EPDM kutchinjiriza kuti musawononge kokondakita. Kusungirako kuyenera kutetezedwa ku kuwala ndi chinyezi, ngakhale kuti nyengo yake imakhala yolimba. Malo oyenerera a crimp akulimbikitsidwa kuti alumikizike, ndipo kuyesa kwamagetsi kuyenera kuchitidwa.
Zoyembekeza Zamsika ndi Zochitika Zachitukuko za EPDM Wire
Pamene dziko likusintha kukhala mphamvu zoyeretsa ndi magetsi, kufunika kwaMtengo wa EPDMakupitiriza kukula. Kufunika kwa zida zotchinjirizira zodalirika kwambiri m'magalimoto atsopano amagetsi, masiteshoni a 5G, malo opangira data, ndi ma grids anzeru kumapangitsa kukula kwa ziro-halogen, low-utsi, ndi magetsi okwera-zambiri. M'tsogolomu, zinthu zophatikizika za EPDM zitha kupititsa patsogolo mphamvu za dielectric ndi mphamvu zamakina kuti zikwaniritse zofunikira za-zomaliza mongaHVDC (high voltage direct current) chingwe zowonjezera.
Posankha-zapamwambaMtengo wa EPDMogulitsa, tikulimbikitsidwa kuti tiyike patsogolo makampani omwe ali ndi satifiketi yathunthu ya UL kuti atsimikizire kusasinthika kwa batch ndi chithandizo chaukadaulo. Mwachitsanzo, fakitale yathu ndi akatswiri kwambiri.
Mapeto
Mtengo wa EPDM, makamaka mitundu yogwirizana ndi miyezo ya UL3311 ndi UL3279, ndiye njira yabwino yolumikizira magetsi akumafakitale chifukwa cha magwiridwe antchito ake, ziphaso zodalirika zachitetezo, komanso kugwiritsa ntchito kwake. Amapereka chitetezo chokhazikika chamagetsi komanso chitetezo chamakina, kaya m'malo ovuta kapena zida zolondola zamkati. Masiku ano kufunafuna kuchita bwino, chitetezo, ndi chitukuko chokhazikika, kumvetsetsa ndikugwiritsa ntchito moyeneraMtengo wa EPDMadzawonjezera chitsimikizo cholimba ku ntchito zanu.
