ʻO nā mea maikaʻi a me nā pōʻino o ka hose kaila EPDM

Hebei conqi Auto Parts Co., Ltd. he 10 mau makahiki o ka ʻike i ka extruding rubber a me nā huahana plastic e kaʻana like me ʻoe i nā pono a me nā hemahema o nā hose EPDM: ke kūʻokoʻa o ka wā kahiko, ka hana insulation uila a me ka hana kūʻē ozone.ʻOi aku ka maikaʻi o ka wā, ka pale ʻana o ka ozone, ka pale wela, ka wai a me ka pale alkali, ka pale ʻana i ka wai, ka paʻa o ka waihoʻoluʻu, nā waiwai uila, ka hoʻopiha ʻana i ka aila a me ka wai wela maʻamau no nā kinikona polar like ʻole e like me ka waiʻona, nā waikawa, nā alkalis, oxidants, refrigerants, Detergents, holoholona. a me nā aila mea kanu, nā ketones a me nā momona a pau ke kū'ē maikaʻi;akā naʻe, ʻaʻole paʻa lākou i nā mea hoʻoheheʻe aliphatic a me nā mea ʻala (e like me ka ʻaila, benzene, etc.) a me nā aila mineral.Ma lalo o ka hana lōʻihi o ka waika concentrated, e emi iho ka hana, a ʻoi aku ka maikaʻi o ka pale ʻana i ka wai 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.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.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 kā mākou hale hana i hana i nā hoʻokolohua he nui a ʻoi aku ka nui o ka hana, a ʻo ka hoʻonui ʻana i nā mea maka a me ka ʻenehana ua hoʻopōkole mālie i ke āpau ma waena o nā pono a me nā hemahema o nā paipu epdm a ʻoi aku ka paʻa.Eia nō naʻe, pono e koho i nā mea kūpono loa no nā mea kūʻai mai ka manaʻo o nā pono o ka mea kūʻai aku.huahana.
