Ma nā ʻoihana hea i hoʻohana nui ʻia ai ka acrylonitrile?

Hana ʻia ʻo Acrylonitrile me ka propylene a me ka ammonia ma ke ʻano he kumu kumu ma o ka hopena oxidation a me ka hana hoʻomaʻemaʻe.He ʻano mea hoʻohui organik, ʻo C3H3N ka wai kala ʻole me ka ʻala ʻala, hiki ke puhi ʻia, hiki i kona mahu a me ka ea ke hana i kahi hui pahū, inā he ahi hāmama, maʻalahi ka wela kiʻekiʻe e hoʻokuʻu i nā kinoea ʻona. , a me nā oxidants, nā ʻakika ikaika, nā kumu ikaika, nā amine, ka hopena bromine.

Hoʻohana nui ʻia e like me ka mea maka no ka fiber acrylic a me ka resin ABS / SAN.Eia kekahi, hoʻohana nui ʻia i ka hana ʻana o ka acrylamide, paste a adiponitrile, synthetic rubber, Latex, etc.

Nā noi mākeke Acrylonitrile

He mea waiwai nui ka Acrylonitrile o ʻekolu mau mea synthetic (plastic, synthetic rubber, synthetic fiber).Hoʻopili ʻia ka hoʻohana ʻana o ka acrylonitrile i lalo i nā kahua ʻekolu o ABS, acrylic a me acrylamide, i helu ʻia ma mua o 80% o ka pau ʻana o ka acrylonitrile.I nā makahiki i hala iho nei, me ka hoʻomohala ʻana o nā mea hana hale a me nā ʻoihana kaʻa, ua lilo ʻo Kina i hoʻokahi o ka ulu wikiwiki ʻana o ka mākeke acrylonitrile o ka honua.Hoʻohana nui ʻia nā huahana i lalo i nā mea pono hale, nā lole, nā kaʻa, nā lāʻau lapaʻau a me nā wahi ʻē aʻe o ka ʻoihana aupuni.

Hana ʻia ʻo Acrylonitrile e ka hopena oxidation a me ka hoʻomaʻemaʻe ʻana o ka propylene a me ka wai amonia.Hoʻohana nui ʻia ia i ka hana ʻana o ka resin a me ka ʻoihana fiber acrylic.ʻO ka carbon fiber ke kahua noi me ka ulu wikiwiki o ka noi i ka wā e hiki mai ana.

Ma ke ʻano he mea nui i lalo o ka acrylonitrile, carbon fiber kahi mea hou i noiʻi nui ʻia a hoʻomohala ʻia ma Kina.Ua lilo ʻo carbon fiber i mea nui o nā mea māmā, a me ka liʻiliʻi mai nā mea metala i hala, ua lilo ia i mea noi kumu ma nā kahua kīwila a me ka pūʻali koa.

Me ka hoʻomau wikiwiki ʻana o ka hoʻokele waiwai o ko mākou ʻāina, ke piʻi nei ke koi no ka carbon fiber a me kāna mea composite.Wahi a nā helu helu kūpono, ʻo ke koi o Kina no ka carbon fiber i hōʻea i 48,800 tons i 2020, kahi piʻi o 29% i hoʻohālikelike ʻia me 2019.

Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, hōʻike ka mākeke acrylonitrile i kahi ʻano hoʻomohala nui:

Hoʻokahi ka propane e like me ka laina hana acrylonitrile maka i ka hoʻolaha lohi;

ʻO ka lua, ʻo ka noiʻi ʻana i nā catalysts hou ke kumuhana noiʻi o ka poʻe naʻauao kūloko a me nā haole;

ʻO ke kolu, ka mea hana nui;

ʻO ka hā, ka mālama ʻana i ka ikehu a me ka emi ʻana o ka hoʻokuʻu ʻana, ʻoi aku ka nui o ka hoʻoponopono ʻana i ke kaʻina hana;

ʻO ka lima, ua lilo ka mālama ʻana i ka wai ʻino i mea noiʻi koʻikoʻi.
