1. Haʻahaʻa haʻahaʻa a me ka hoʻopiha kiʻekiʻe
ʻO ka mānoanoa o ka ethylene propylene rubber he ʻano o ka lāʻau haʻahaʻa, a ʻo kona density he 0.87.Eia kekahi, hiki ke hoʻopiha ʻia ka nui o ka aila a hiki ke hoʻohui ʻia nā mea hoʻopihapiha, no laila hiki ke hoʻemi ʻia ke kumukūʻai o nā huahana rubber, a hiki ke hana ʻia ka hemahema o ke kumukūʻai kiʻekiʻe o ka ethylene-propylene rubber raw rubber.No ka ethylene-propylene rubber me ka waiwai Mooney kiʻekiʻe, hiki ke hoʻemi ʻia ka ikehu kino a me ka mechanical ma hope o ka hoʻopiha kiʻekiʻe.ʻaʻole nui.
2. Ke kū'ē i ka wā kahiko
ʻO ka ethylene-propylene rubber ka maikaʻi loa o ka wā, ke kū'ē ozone, ke kū'ē wela, kaʻakika a me ke kūpaʻa alkali, ke kū'ēʻana o ka mahu wai, ka paʻa o ka waihoʻoluʻu, nā waiwai uila, ka hoʻopihaʻana i kaʻaila a me ka wai wela o ka lumi.Hiki ke hoʻohana ʻia nā huahana ethylene-propylene rubber no ka manawa lōʻihi ma 120 ° C, a hiki ke hoʻohana ʻia no ka manawa pōkole a i ʻole intermittent ma 150-200 ° C.ʻO ka hoʻohui ʻana i kahi mea kūʻē i ka wā kahiko hiki ke hoʻonui i ka mahana lawelawe.Hiki ke hoʻohana ʻia ka ʻōpala EPDM i hoʻopili ʻia me ka peroxide ma lalo o nā kūlana paʻakikī.Ma lalo o nā kūlana o ka ozone o 50pphm a me 30% ka lōʻihi, hiki i ka lāʻau EPDM ke piʻi ma mua o 150h me ka ʻole o ka haki.
3. Ke kū'ē i ka corrosion
Ma muli o ka nele o ka polarity a me ka haʻahaʻa haʻahaʻa o ka unsaturation o ka ethylene-propylene rubber, he kūʻē maikaʻi ia i nā ʻano mea like ʻole polar e like me nā alcohols, acids, alkalis, oxidants, refrigerants, detergents, holoholona a me nā aila mea kanu, ketones a me nā momona, etc. ;Akā, i loko o aliphatic a me ka aromatic solvents (e like me gasoline, benzene, etc.) a me ka ilihune stability i loko o ka mineral aila.E emi ana ka hana ma lalo o ka hana lōʻihi o ka waikawa concentrated.
4. Ke kū'ē i ka mahu wai
ʻOi aku ka maikaʻi o ka ethylene-propylene rubber ma mua o kona kūpaʻa wela.I loko o ka mahu wela loa ma 230°C, ʻaʻohe loli i ka helehelena ma hope o 100 hola.Ma lalo o nā kūlana like, fluororubber, silicone rubber, fluorosilicone rubber, butyl rubber, nitrile rubber, a me ka lāʻau maoli e ʻike i ka pōʻino o ka helehelena ma hope o kahi manawa pōkole.
5. Ke kū'ē i ka wai wela nui
ʻOi aku ka maikaʻi o ke kūʻē ʻana o ka ethylene-propylene rubber i ka wai wela, akā pili pili i nā ʻōnaehana vulcanization āpau.ʻO ka ethylene-propylene rubber me ka dimorpholine disulfide a me ka TMTD e like me ka ʻōnaehana vulcanization he liʻiliʻi ka hoʻololi ʻana i nā waiwai mechanical ma hope o ka hoʻonā ʻia ʻana i ka wai wela nui ma 125 ° C no 15 mau mahina, a ʻo 0.3% wale nō.
6. Nā waiwai uila
ʻOi aku ka maikaʻi o kona mau waiwai uila ma mua a kokoke paha i ko ka styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene a me ka polyethylene cross-linked.
7. Elasticity
No ka mea, ʻaʻohe polar substituents i loko o ka molecular structure of ethylene-propylene rubber, haʻahaʻa ka ikehu cohesive o ka mole, a hiki i ke kaulahao mole ke hoʻomau i ka maʻalahi ma kahi ākea, ʻelua wale nō i ka ʻōpala maoli a me ka pulupulu butadiene, a hiki ke mālama mau. ma ka wela haʻahaʻa.
8. Hoʻopili
Ma muli o ka nele o nā pūʻulu ikaika i ka molecular structure o ka ethylene-propylene rubber, ua haʻahaʻa ka ikehu cohesive, a ua maʻalahi ka pua, a ʻo ka hoʻopili ponoʻī a me ka hoʻopili like ʻana he ʻilihune loa.
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.
