Acrylonitrile whakamahia i roto i te kirihou me te kapia,
Acrylonitrile Mo nga Resin ABS, Acrylonitrile Mo te ASA, Acrylonitrile Mo te NBR, Acrylonitrile Mo SAN, Acrylonitrile Mo te SAR,
Ko te Acrylonitrile (ACN), he puhui pararopi, he wai kore tae me te wai marama i puta mai i te propylene me te haukini.He tauhohenga, he paitini te ahua;heoi, e mohiotia ana mo tona kaha me tona mauroa.
He monomer e whakaputa ana i te polyacrylonitrile, he homopolymer, copolymers penei i te muka kiriaku, acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN), acrylonitrile styrene acrylate (ASA) me etahi atu rapa penei i te acrylonitrile butadiene (NBR). nga tono kaiwhakamahi mutunga nui.O nga tono-kaiwhakamahi mutunga, ko te ABS thermoplastic ka nui ake i te 35 paiheneti o te katoa o te tono whai muri mai i nga muka kiriaku me te wahanga tono mo te 27 paiheneti.Tata ki etahi tau kua pahure ake nei, ko nga muka kiriaku te waahanga nui o te tono, engari kua puhoi haere te rongonui a ABS i te tuara o tona kaha, te mauroa me te aukati wera e hiahiatia ana i roto i nga tono maha.He maha nga taputapu (puera pouaka, kihini, aha atu), hiko me te hikohiko, me te umanga miihini ko nga kaiwhakamahi mutunga nui o ABS.Ko nga muka kiriaku kei te ata whakakapihia e nga muka polyester i runga i te utu iti me te ngawari o te tukurua.Ka whakamahia ano te Acrylonitrile hei takawaenga ki te whakaputa Acrylamide, e 15 paiheneti o te katoa o te hiahia, e whakaputa ana i te polyacrylamide (PAM) e whakamahia ana i roto i nga tono maimoatanga wai para.
Ko te kaha o te whakaputanga o te ao o ACN kei te tata ki te 10 piriona pauna ia tau.Neke atu i te 40 paiheneti o Ahia-Kiwa na te tipu o te umanga hangahanga i roto i nga maakete hou penei i Haina me Inia.Ko Uropi te tuarua o nga rohe nui rawa atu i muri mai i Amerika Te Tai Tokerau mo te kaha o te whakaputa.Kua whakakotahihia te maakete kaiwhakarato ACN, ko etahi o nga kaihanga nui ko INEOS Capital Limited, Ascend Performance Materials, AnQore me Mitsubishi Chemical Corporation.

Ko te Acrylonitrile he mea hanga arumoni na roto i te ammoxidation propylene, ka tauhohehia te propylene,ammonia, me te hau e te whakakorikori i roto i te moenga wai.Ka whakamahia te Acrylonitrile hei monomer tahi i roto i te hanga o nga muka kiriaku me nga muka modacrylic.Ko nga whakamahinga ko te hanga kirihou, paninga mata, elastomers nitrile, kapia arai, me te whakapiri.He takawaenga matū hoki i roto i te whakahiato o nga momo antioxidants, ho'oraa, waikano, me te mahi-mata.
1. Acrylonitrile hanga o polyacrylonitrile muka, ara kiriaku muka.
2. Ka taea te kape i te kirikiri me te butadiene ki te hanga i te rapa nitrile.
