Kodi payipi ya rabara ya EPDM ndi chiyani

EPDM (Ethylene Propylene Diene Monomer) ndi copolymer ya ethylene, propylene ndi diene yaing'ono yopanda conjugated.Ndi mtundu wa mphira wa ethylene propylene.Kupangidwa, kokha lili unsaturated zomangira awiri mu unyolo mbali, choncho ali kwambiri kukana ukalamba monga kukana ozoni, kukana kutentha, ndi kukana nyengo, ndipo chimagwiritsidwa ntchito mbali magalimoto, zipangizo madzi pomanga, waya ndi chingwe m'chimake, kutentha -mapaipi osagwira, matepi, Zisindikizo zamagalimoto ndi magawo ena.

Chofunikira kwambiri cha EPDM ndi kukana kwake kwa okosijeni kwapamwamba, kukana kwa ozoni komanso kukana dzimbiri.Popeza EPDM ndi ya banja polyolefin, ali kwambiri vulcanization makhalidwe.Pakati pa ma rubbers onse, EPDM ili ndi mphamvu yokoka yotsika kwambiri ndipo imatha kuyamwa mafuta ambiri odzaza ndi mafuta omwe alibe zotsatira zochepa pa katundu, kotero kuti mankhwala otsika mtengo a rabara apangidwe.

EPDM rabara ndi terpolymer wa ethylene, propylene ndi non-conjugated dienes.Dienes ali ndi dongosolo lapadera.Panthawi ya copolymer reaction, imodzi yokha yogwira ntchito iwiri imagwira nawo ntchito, pamene mgwirizano wotsalira wapawiri wokhala ndi ntchito zochepa umakhalabe pa unyolo wa ma molekyulu a copolymer monga malo osasunthika.Sulfur vulcanization idagwiritsidwa ntchito.Chimodzi chokha mwa zomangira ziwirizi zitha kukhala copolymerized, ndipo chomangira chaunsaturated pawiri chimagwiritsidwa ntchito ngati cholumikizira.Zina zopanda unsaturated sizidzakhala msana wa polima, unyolo wam'mbali wokha.Unyolo waukulu wa polima wa EPDM ndiwodzaza.Katunduyu amapangitsa EPDM kugonjetsedwa ndi kutentha, kuwala, mpweya, makamaka ozoni.EPDM ndi yopanda polar mwachilengedwe, yosagwirizana ndi njira za polar ndi mankhwala, imakhala ndi madzi ochepa, ndipo imakhala ndi zinthu zabwino zotetezera.

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.
