Loaʻa i ka NBR ke kūpaʻa aila maikaʻi, ʻilihune ka EPDM i ka pale ʻana i ka aila a ʻaʻole paʻa, akā hiki ke pale i ka ʻelemakule a me ka wela.ʻO ka maʻamau, hoʻohana nui ʻia ka EPDM no nā paipu wai a ma luna o ka mahu;ʻOi aku ka maikaʻi o ka EPDM i ka pale ʻana i ka friction.
1. ʻO ka nitrile rubber NBR he polar unsaturated carbon chain rubber, kahi i copolymerized mai ka acrylonitrile a me ka butadiene.Ma muli o ka ʻike o ka acrylonitrile mai ka haʻahaʻa a hiki i ke kiʻekiʻe, hoʻonui ʻia ka pale ʻana i ka ʻaila, akā ua hoʻemi ʻia ke kū anuanu.
ʻO ke kūpaʻa aila ka hiʻohiʻona nui loa o ka NBR nitrile rubber, he kūʻē maikaʻi i ka ʻaila a me nā solvents non-polar, akā maikaʻi ʻole ke kūʻē ʻana i nā aila polar a me nā solvents polar.
1. Ka waiwai antistatic maikaʻi;
2. Poor ozone kū'ē;
3. He kūpono maikaʻi ia me nā mea polar, e like me ka polyvinyl chloride (PVC), polyoxymethylene (POM), nylon, a hiki ke hana ʻia i nā mea hao a me nā mea plastic.
4. ʻO ka pae wela hana o ka nitrile rubber maʻamau: -20 ° C ~ 120 ° C, a hiki ke emi iho nā ʻano haʻahaʻa haʻahaʻa ma lalo o -50 ° C;
2. Hoʻohana ka ethylene-propylene rubber i ka ethylene a me ka propylene ma ke ʻano he synthetic raw material, a hiki ke hoʻokaʻawale ʻia i ka binary ethylene-propylene rubber (EPM) a me ka tertiary ethylene-propylene rubber (EPDM).
Nā waiwai o ka ethylene propylene rubber:
1. Ozone elemakule kū'ē
2. Kū'ē i ka wā
3. Kūleʻa wela
ʻO nā waiwai i luna ʻekolu ka mea maikaʻi loa i ka lāʻau lapaʻau.Aia kekahi mau waiwai
4. ʻOi aku ka maikaʻi o ka pale ʻana i ka wai, ke kūpaʻa superheat a me ke kū ʻana o ka mahu wai;
5. Paipai kemika maikaʻi;
(Ma muli o ka paʻa ʻana o ke kemika a me ka polarity ʻole o ka ethylene-propylene rubber ponoʻī, ʻaʻole ia e hana kemika me ka hapa nui o nā kemika, ʻaʻole kūpono a i ʻole ka liʻiliʻi o ka hoʻohālikelike ʻana me nā mea polar, a kūʻē i ka waiʻona, waika, alkali ikaika, oxidizing. nā mea hana, nā mea holoi holoi, nā aila holoholona a me nā mea kanu, nā ketones, etc.)
ʻOi aku ka palupalu o ka NBR, ʻoi aku ka paʻakikī o ka EPDM a he ʻono ʻokoʻa
1. ʻO nā wahi nui o ka Rubber
(1) Kāpena maʻamau: e like me NR / BR / SBR / EPDM
(2) Kūikawā kūikawā: e like me SR/FPM/CIIR/HNBR/CSM 2.
ʻO ka ʻaila nitrile NBR maikaʻi ka pale ʻana i ka aila, i ʻike mau ʻia ʻo ka ʻaila-proof rubber, a hoʻohana pinepine ʻia e like me ke sila aila.
He elasticity maikaʻi ka NR rubber kūlohelohe a maikaʻi ka hana holoʻokoʻa, akā maikaʻi ʻole ke kūpaʻa anu a me ke kūpaʻa alkali.Hoʻohana pinepine ʻia e like me nā kaʻa kaʻa
ʻO Styrene Butadiene Rubber SBR ʻO ka pahu liʻiliʻi loa ma ka honua, i hoʻohana ʻia ma ke ʻano he pad
Loaʻa i ka EPDM ke kūpaʻa corrosion maikaʻi a me ka insulation maikaʻi, a hiki ke hoʻohana ʻia e like me nā mea ʻaʻahu a i ʻole nā mea uila uila kiʻekiʻe.
ʻO ka Neoprene CR he pale lole maikaʻi a hiki ke hoʻohana ʻia ma ke ʻano he cushion Chlorosulfonated polyethylene CSM he kūpaʻa anuanu maikaʻi.
Polytetrafluoroethylene PTFE
ʻO ke aliʻi plastik, ka waikawa maikaʻi a me ke kūpaʻa alkali, hiki ke kū i ka waika hydrofluoric.Loaʻa iā ia ka nui o ka hoʻohana ʻana a hiki ke hoʻohana ʻia ma ke ʻano he pipeline no nā wai corrosive.
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.
