Acrylonitrile no PAN
Acrylonitrile no PAN,
Acrylonitrile No ka Polyacrylonitrile, Acrylonitrile no ka polyacrylonitrile fiber,
ʻO ka Polyacrylonitrile (PAN) he polymer synthetic me ke ʻano laina laina (C3H3N)n.ʻOiai he thermoplastic ʻaʻole ia e hoʻoheheʻe ma lalo o nā kūlana maʻamau, no ka mea, hoʻohaʻahaʻa ia ma mua o ka hoʻoheheʻe ʻana ma luna o 300 °C.Aneane pau nā resins PAN he copolymers i hana ʻia mai nā hui ʻana o nā monomers, me ka acrylonitrile ka mea nui.ʻO ia ka polymer versatile i hoʻohana ʻia e hana i nā ʻano huahana like ʻole, me nā fibers no ka textiles, ultra-filtration membranes, hollow fibers no reverse osmosis, etc.

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.
