Acrylonitrile no NBR
Acrylonitrile no NBR,
Acrylonitrile No ka Nitrile Rubber,
ʻO Nitrile (i kapa pinepine ʻia ʻo buna-N rubber a i ʻole perbunan) ka elastomer maʻamau i hoʻohana ʻia i ka ʻoihana sila.ʻO ka Nitrile he copolymer o ʻelua monomers: acrylonitrile (ACN) a me ka butadiene.Hoʻoholo ʻia nā waiwai o kēia mau pūhui kopa e kona ʻike ACN, i wāwahi ʻia i ʻekolu papa:
Nitrile kiʻekiʻe> 45% ACN maʻiʻo,
ʻO ka nitrile waena 30-45% maʻiʻo ACN,
Haʻahaʻa nitrile <30% ACN maʻiʻo.
ʻOi aku ka kiʻekiʻe o ka ʻike ACN, ʻoi aku ka maikaʻi o kona kūʻē ʻana i nā aila hydrocarbon.ʻO ka haʻahaʻa o ka ʻike ACN ʻoi aku ka maikaʻi o kona maʻalahi i nā noi wela haʻahaʻa.No laila, ʻoi aku ka nui o ka wehewehe ʻana o ka nitrile ma muli o kona kaulike holoʻokoʻa maikaʻi i ka hapa nui o nā noi.ʻO ka mea maʻamau, hiki ke hoʻohui ʻia nā nitriles e hana ma luna o ke ana wela o -35°C a i +120°C a ʻoi aku ka maikaʻi ma mua o ka hapa nui o nā elastomers e pili ana i ka hoʻonohonoho hoʻopaʻa ʻana, ka waimaka a me ke kūpaʻa abrasion.

Hoʻohana Huahana
Hoʻokumu ʻia ka Acrylonitrile e ka propylene ammoxidation, kahi e hoʻopili ʻia ai ka propylene, ammonia, a me ka ea e ka catalyst i kahi moena wai.Hoʻohana nui ʻia ka Acrylonitrile ma ke ʻano he co-monomer i ka hana ʻana i nā fibers acrylic a me modacrylic.Hoʻohana ʻia ka hana ʻana o nā plastics, nā uhi ʻili, nā elastomers nitrile, nā pale pale, a me nā mea hoʻopili.ʻO ia hoʻi kahi mea waena kemika i ka synthesis o nā antioxidants like ʻole, nā lāʻau lapaʻau, nā mea ʻulaʻula, a me ka surface-active.
1. ʻO Acrylonitrile i hana ʻia me ka polyacrylonitrile fiber, ʻo ia hoʻi ka fiber acrylic.
2. Hiki ke copolymerized ka Acrylonitrile a me ka butadiene e hana i ka nitrile rubber.
3. Acrylonitrile, butadiene, styrene copolymerized e hoʻomākaukau i ka resin ABS.
4. Hiki i ka Acrylonitrile hydrolysis ke hana i ka acrylamide, ka waikawa acrylic a me kāna esters.
