He aha ka EPDM hose

ʻO EPDM (Ethylene Propylene Diene Monomer) he copolymer o ka ethylene, propylene a me kahi liʻiliʻi o ka diene non-conjugated.He ʻano ethylene propylene rubber.ʻO ka haku mele, aia wale nō nā paʻa pālua unsaturated i ke kaulahao ʻaoʻao, no laila he kūʻokoʻa maikaʻi loa e like me ke kūʻē ozone, ke kū ʻana o ka wela, a me ka pale ʻana i ka wā, a hiki ke hoʻohana nui ʻia i nā ʻāpana kaʻa, nā mea wai wai no ke kūkulu ʻana, nā uea a me nā sheaths, wela. - nā hoses kūʻokoʻa, nā lipine , nā sila automotive a me nā māla ʻē aʻe.

ʻO ka hiʻohiʻona koʻikoʻi o ka EPDM ʻo ia ke kūpaʻa ʻana o ka oxidation kiʻekiʻe, ke kūpaʻa ozone a me ke kūpaʻa corrosion.No ka mea nona ka EPDM i ka ʻohana polyolefin, loaʻa iā ia nā hiʻohiʻona vulcanization maikaʻi loa.Ma waena o nā ʻōpala āpau, ʻo ka EPDM ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a hiki ke komo i ka nui o nā mea hoʻopihapiha a me nā aila me ka liʻiliʻi o ka hopena i nā waiwai, i hiki ke hana ʻia nā mea hoʻohui haʻahaʻa haʻahaʻa.

He terpolymer ka EPDM rubber o ka ethylene, propylene a me nā diene non-conjugated.He hale kūikawā ko Dienes.I loko o ka hopena copolymer, hoʻokahi wale nō mea paʻa paʻa paʻa i komo i ka hopena, aʻo ke koena paʻa pālua me ka liʻiliʻi o ka hana e mau ana ma ke kaulahao molekala copolymer ma ke ʻano he wahi unsaturation no ka lako.Ua hoʻohana ʻia ka vulcanization sulfur.Hoʻokahi wale nō o nā mea paʻa ʻelua e hiki ke kope ʻia, a hoʻohana nui ʻia ka paʻa pālua unsaturated ma ke ʻano he loulou keʻa.ʻAʻole e lilo nā mea i hoʻopiha ʻole ʻia i ka iwi kuamoʻo polymer, nā kaulahao ʻaoʻao wale nō.Ua piha piha ke kaulahao polymer nui o EPDM.Mālama kēia waiwai iā EPDM i ka wela, ka māmā, ka oxygen, a me ka ozone.ʻAʻole polar ka EPDM ma ke ʻano, kūpaʻa i nā hoʻonā polar a me nā kemika, haʻahaʻa haʻahaʻa ka wai, a loaʻa nā waiwai insulating maikaʻi.

ʻO Hebei CONQI VEHICLE FITTINGS Co., Ltd. he hui i hoʻolaʻa ʻia no ka hana ʻana a me ka puʻunaue ʻana i ka hose kaʻa kaʻa, ka paipu EPDM, ka hose meaʻai a me ka pvc hose etc.I ka makahiki 2009, ua hoʻopau ka hui i ka nui o ka waiwai hoʻopuka hana ʻoihana o 10.01 miliona yuan a ua hoʻopau i kahi ʻauhau hale kūʻai o 250,000 yuan.Hoʻohālikelike ʻia lākou āpau me 30 mau OEM home e like me Jinlong, Yutong, Ankai, a me Zhongtong, a me nā lālā honua o Volvo a me India, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Egypt, Spain, Turkey, Ua loaʻa i Brazil, Singapore, Kelemānia a ʻoi aku ma mua o 20 mau ʻāina a me nā ʻāina i nā mea kākoʻo.Hoʻopili i ke kumu o ka "hoʻomaikaʻi mau, ka maikaʻi, ka maikaʻi maikaʻi, a me ka ʻoluʻolu o nā mea kūʻai aku", hopu mākou i ka ʻenehana honua hou a me ka ʻike huahana, hoʻolālā mau a hoʻomohala i nā huahana hou, a hāʻawi i nā mea kūʻai aku.
