Acrylonitrile inogadzirwa nekushandisa propylene uye ammonia semidziyo yakabikwa, kuburikidza nekuita oxidation uye kunatsa maitiro.Iyo organic compound ine kemikari formula C3H3N, mvura isina ruvara ine kunhuhwirira, inopfuta, mhute yaro nemhepo zvinogona kuita musanganiswa unoputika, uye zviri nyore kukonzera kupisa kana yakafumurwa murazvo wakavhurika uye kupisa kwakanyanya, uye inoburitsa gasi rine muchetura. , uye inopindirana nechisimba ne oxidizers, yakasimba acids, mabhesi akasimba, amines uye bromine.

Inonyanya kushandiswa seyakabikwa acrylic uye ABS/SAN resin, uye zvakare inoshandiswa zvakanyanya mukugadzirwa kweacrylamide, paste uye adiponitrile, synthetic rabha, Latex, nezvimwe.

Acrylonitrile Market Applications

Acrylonitrile chinhu chakakosha mbishi kune matatu makuru ekugadzira zvinhu (mapurasitiki, ekugadzira rabha uye synthetic fibers), uye kudzika kwemvura kudyiwa kweacrylonitrile muChina kwakanyanya muABS, acrylic uye acrylamide, iyo inodarika 80% yehuwandu hwekushandisa. acrylonitrile.Mumakore achangopfuura, China yave imwe yenyika dziri kukurumidza kukura mumusika wepasi rose weacrylonitrile nekuvandudzwa kwemidziyo yemumba uye maindasitiri emotokari.Zvigadzirwa zvepasi pemvura zvinoshandiswa zvakanyanya munzvimbo dzakasiyana dzehupfumi hwenyika, senge midziyo yemumba, zvipfeko, mota, nemishonga.

Acrylonitrile inogadzirwa kubva kupropylene uye ammonia neoxidation reaction uye yekunatsa maitiro, uye inoshandiswa zvakanyanya muresin, acrylic kugadzirwa kwemaindasitiri, uye kabhoni fiber inzvimbo dzekushandisa dzinokura nekukurumidza kudiwa mune ramangwana.

Carbon fiber, seimwe yeakakosha mashandisirwo pasi pemvura yeacrylonitrile, chinhu chitsva chiri kutariswa pakutsvaga nekusimudzira uye kugadzira muChina.Carbon fiber yave nhengo yakakosha yezvinhu zvisingaremi, uye zvishoma nezvishoma inotora simbi yapfuura, uye yave iyo yakakosha yekushandisa muminda yevagari nemauto.

Sezvo hupfumi hweChina hunoramba huchikura nekukurumidza, kudiwa kwekabhoni fiber uye zvinhu zvayo zvakaumbwa kuri kuramba kuchikwira.Zvinoenderana nehuwandu hwakakodzera, kudiwa kwekabhoni fiber muChina kunosvika 48,800 matani muna 2020, kuwedzera kwe29% pamusoro pe2019.

Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, musika weacrylonitrile unoratidza maitiro makuru ebudiriro.
Kutanga, nzira yekugadzirwa kweacrylonitrile uchishandisa propane se feedstock iri kusimudzirwa zvishoma nezvishoma.
Chechipiri, kutsvagisa kwezvinokonzeresa kunoramba kuri nyaya yekutsvagisa yevadzidzi vekumba nevekunze.
Chechitatu, chiyero chikuru chechirimwa.
Chechina, kuchengetedza simba uye kuderedza emission, kugadzirisa mashandiro ari kuwedzera kukosha.
Chechishanu, kurapwa kwemvura yakasviba kwave chinhu chakakosha chekutsvaga.

Acrylonitrile Makuru Kukwanisa Kugadzira

Zvivakwa zvekuChina zvekumba zvekugadzira acrylonitrile zvakanyanya kunyanya mumabhizinesi eChina Petroleum & Chemical Corporation (Sinopec) neChina National Petroleum Corporation (CNPC).Pakati pavo, huwandu hwekugadzira huwandu hweSinopec (kusanganisira majoint ventures) i860,000 matani, inoverengera 34.8% yehuwandu hwekugadzira huwandu;simba rekugadzira rePetroChina i700,000 matani, inoverengera 28.3% yehuwandu hwekugadzira huwandu;kugona kugadzira kwemabhizinesi akazvimirira ega Jiangsu Searborn Petrochemical, Shandong Haijiang Chemical Co.

Kubva chikamu chechipiri che2021, chikamu chechipiri cheZPMC chine 260,000 matani / gore, chikamu chechipiri cheKruel ine 130,000 matani / gore, chikamu chechipiri cheLihua Yi ne260,000 matani / gore uye chikamu chechitatu cheSrbang chine 260,000 matani / gore re acrylonitrile rakaiswa mukushanda rimwe pashure peimwe, uye hutsva hutsva hwasvika 910,000 matani / gore, uye iyo yose yepamusha acrylonitrile simba yasvika mamiriyoni 3.419 matani / gore.

Kuwedzera kweacrylonitrile simba hakuregi pano.Zvinonzwisisika kuti mu2022, itsva 260,000 matani / gore acrylonitrile chirimwa chichaiswa mukushanda muEast China, 130,000 matani / gore chirimwa muGuangdong uye 200,000 matani / gore chirimwa muHainan.Hunhu hutsva hwekugadzira mudzimba hausisiri kuEast China chete, asi huchagoverwa mumatunhu akati wandei muChina, kunyanya chirimwa chitsva muHainan chichaiswa mukushanda kuitira kuti zvigadzirwa zvive pedyo neSouth China neSoutheast Asia misika, uye zvakare iri nyore kwazvo kutengesa kunze kwenyika negungwa.

Iyo yakawedzera zvakanyanya kugadzirwa kugona kunounza kukwira mukugadzirwa.Huwandu hweJinlian hunoratidza kuti kugadzirwa kweacrylonitrile kuChina kwakaramba kuchiwedzera kutsva muna 2021. Pakupera kwaZvita 2021, kugadzirwa kwemumba kweacrylonitrile kwakapfuura matani 2.317 miriyoni, zvichikwira 19% gore negore, nepo kushandiswa kwepagore kwaisvika matani 2.6 miriyoni. , nezviratidzo zvekutanga zvekuwandisa muindasitiri.
