1. Kutsika kochepa komanso kudzaza kwakukulu
Kachulukidwe mphira ethylene propylene ndi mtundu wa mphira m'munsi, ndi kachulukidwe ake ndi 0,87.Kuonjezera apo, mafuta ochuluka amatha kudzazidwa ndi zodzaza zikhoza kuwonjezeredwa, kotero kuti mtengo wamtengo wapatali wa mphira ukhoza kuchepetsedwa, ndipo kuipa kwa mtengo wapamwamba wa mphira wa ethylene-propylene mphira waiwisi ukhoza kupangidwira.Kwa mphira wa ethylene-propylene wokhala ndi mtengo wapamwamba wa Mooney, mphamvu yakuthupi ndi yamakina imatha kuchepetsedwa pambuyo podzaza kwambiri.osati chachikulu.
2. Kukana kukalamba
Rabara ya ethylene-propylene imakhala ndi kukana kwanyengo yabwino, kukana kwa ozoni, kukana kutentha, asidi ndi kukana kwa alkali, kukana kwa nthunzi wamadzi, kukhazikika kwamtundu, mphamvu zamagetsi, kudzaza mafuta ndi kutentha kwachipinda.Mankhwala a rabara a ethylene-propylene amatha kugwiritsidwa ntchito kwa nthawi yayitali pa 120 ° C, ndipo atha kugwiritsidwa ntchito kwakanthawi kapena pang'onopang'ono pa 150-200 ° C.Kuonjezera odana ndi ukalamba wothandizira akhoza kuonjezera kutentha kwa utumiki wake.EPDM mphira crosslinked ndi peroxide angagwiritsidwe ntchito pazovuta kwambiri.Pansi pazikhalidwe za ozoni ndende ya 50pphm ndi kutambasula kwa 30%, mphira wa EPDM ukhoza kufika kupitirira 150h popanda kusweka.
3. Kukana dzimbiri
Chifukwa chosowa polarity ndi otsika digiri unsaturation wa mphira ethylene-propylene, ali bwino kukana zosiyanasiyana polar mankhwala monga alcohols, zidulo, alkalis, okosijeni, refrigerants, zotsukira, nyama ndi masamba mafuta, ketoni ndi mafuta, etc. ;Koma mu aliphatic ndi onunkhira solvents (monga mafuta, benzene, etc.) ndi osauka bata mu mchere mafuta.Kuchitako kudzatsikanso pansi pakuchita kwanthawi yayitali kwa asidi wokhazikika.
4. Kukana kwa nthunzi wa madzi
Rabara ya ethylene-propylene imakhala ndi mphamvu yabwino kwambiri yolimbana ndi nthunzi yamadzi ndipo imadziwika kuti ndiyopambana kuposa kukana kwake kutentha.Mu nthunzi yotentha kwambiri pa 230 ° C, palibe kusintha kwa mawonekedwe pambuyo pa maola pafupifupi 100.Pazifukwa zomwezo, mphira wa fluororubber, rabara ya silikoni, labala ya fluorosilicone, labala ya butyl, labala ya nitrile, ndi mphira wachilengedwe zidzawoneka kuwonongeka pakapita nthawi yochepa.
5. Kukana madzi otentha kwambiri
Ethylene-propylene rabara imakhalanso yabwino kukana madzi otentha kwambiri, koma imagwirizana kwambiri ndi machitidwe onse a vulcanization.Ethylene-propylene rabara ndi dimorpholine disulfide ndi TMTD monga vulcanization dongosolo ali ndi kusintha pang'ono mu makina katundu pambuyo ankawaviika m'madzi otentha kwambiri pa 125 ° C kwa miyezi 15, ndi voliyumu kukulitsa mlingo ndi 0.3% yokha.
6. Mphamvu zamagetsi
Ethylene-propylene rabara imakhala ndi mphamvu zabwino kwambiri zotchinjiriza magetsi komanso kukana kwa corona, ndipo mphamvu zake zamagetsi ndizoposa kapena kuyandikira za rabara ya styrene-butadiene, chlorosulfonated polyethylene, polyethylene ndi polyethylene yolumikizana ndi mtanda.
7. Kusangalala
Popeza palibe ma polar olowa m'malo a mphira wa ethylene-propylene, mphamvu yolumikizana ya molekyulu ndi yotsika, ndipo unyolo wa mamolekyu ukhoza kukhalabe wosinthika mosiyanasiyana, wachiwiri kokha ku rabala wachilengedwe ndi mphira wa butadiene, ndipo uthabe kukhalabe. pa kutentha kochepa.
8. Kumamatira
Chifukwa cha kusowa kwa magulu ogwira ntchito m'magulu a mphira a ethylene-propylene, mphamvu yogwirizanitsa imakhala yochepa, ndipo mphirayo ndi yosavuta kuphuka, ndipo kudzimangiriza ndi kugwirizanitsa ndizovuta kwambiri.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. ndi kampani yodzipereka kupanga ndi kugawa payipi ya rabara yamagalimoto, payipi ya EPDM, payipi ya chakudya ndi payipi ya pvc ndi zina zambiri zokhala ndi zopanga zambiri, ukadaulo wapamwamba wopanga komanso dongosolo lathunthu komanso lasayansi loyang'anira.Mu 2009, kampaniyo inamaliza mtengo wamtengo wapatali wa yuan 10.01 miliyoni ndikumaliza msonkho wanyumba yosungiramo katundu wa 250, 000 yuan.Onsewa amafanana ndi ma OEM opitilira 30 apakhomo monga Jinlong, Yutong, Ankai, ndi Zhongtong, komanso nthambi zamayiko a Volvo ndi India, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Egypt, Spain, Turkey, Brazil, Singapore, Germany ndi mayiko ndi madera oposa 20 apeza zothandizira.Potsatira mfundo za "kusintha kosalekeza, kuchita bwino kwambiri, khalidwe labwino kwambiri, ndi kukhutitsidwa ndi makasitomala", timagwira bwino ntchito zamakono zamakono ndi zamakono zapadziko lonse, timapanga nthawi zonse ndikupanga zatsopano, ndikupereka makasitomala.
