Isingeniso: Ngokuthuthuka okuqhubekayo kwezimboni ze-acrylic ne-ABS resin, ukusetshenziswa okusobala kwe-acrylonitrile kukhula njalo ezweni lethu.Kodwa-ke, ukwanda okukhulu komthamo kwenza imboni ye-acrylonitrile manje isesimweni sokugcwala ngokweqile kanye nesidingo.Ngaphansi kokungafani kokunikezwa kanye nesidingo, ukungqubuzana phakathi kokunikezwa nokufunwa kwe-acrylonitrile kuyanda.
Izindawo ezisetshenziswayo ze-Acrylonitrile zisatshalaliswa kakhulu nge-acrylic fiber, i-ABS resin (kuhlanganise ne-SAN resin), i-acrylamide (kuhlanganise ne-polyacrylamide), irabha ye-nitrile nezimboni zamakhemikhali amahle.Ngakho-ke, i-East China iyindawo eyinhloko ye-ABS ephansi yomfula, i-acrylic fiber kanye nomthamo wokukhiqiza we-AM/PAM.Nakuba inani lezitshalo ze-ABS lilincane, amandla okukhiqiza eyunithi ngayinye makhulu, ngakho idivayisi ye-ABS kanye nedivayisi ye-acrylamide yenzela kufikela ku-44% wokusetshenziswa kwe-acrylonitrile.ENyakatho-mpumalanga yeShayina, ikakhulukazi isitshalo se-acrylic fibre esimelelwe i-Jilin chemical fiber, isitshalo se-acrylamide e-Daqing, kanye neyunithi ye-ABS engamathani angu-80,000 eJihua yenza cishe u-23% wesidingo.ENyakatho neChina, i-fiber kanye ne-amide yizimboni eziyinhloko ezansi nomfula, ezibalelwa ku-26%.
Ngokuthuthuka okuqhubekayo kwezimboni ze-acrylic ne-ABS resin, ukusetshenziswa okusobala kwe-acrylonitrile kwanda njalo ezweni lethu.Ikakhulukazi ngo-2018, ngenxa yokugcinwa endaweni eyodwa kwemishini yasekhaya neyangaphandle, intengo ye-acrylonitrile yakhuphuka, futhi inzuzo yake yafinyelela ku-4,000-5,000 yuan/ton, okubangele ukwanda okusheshayo kwamandla okukhiqiza.Ngakho-ke, ngo-2019, ukwanda kwangenisa isikhathi senzuzo, futhi ukusetshenziswa kwayo kwanda kakhulu, nokunyuka ngasikhathi sinye ngo-6.3%.Kodwa-ke, ngokufika kwalolu bhubhane ngo-2020, izinga lokukhula kwalo lehla.Kodwa-ke, ukusetshenziswa okusobala kwemboni ye-acrylonitrile kukhuphuke kakhulu futhi ngo-2021, kukhuphuke ngo-3.9% unyaka nonyaka, ikakhulukazi ngenxa yokusimama komnotho womhlaba kanye nokwenyuka kwevolumu yokuthunyelwa kwempahla kuleli.
Sekukonke, imboni ye-acrylonitrile manje isesimweni sokugcwala ngokweqile, okuye kwabangela imboni yamanje ngisho noma ukukhiqizwa kuncishisiwe, kodwa imakethe namanje ayithuthukisiwe kakhulu, imboni iyaqhubeka nokulahlekelwa inzuzo.Ngaphezu kwalokho, ingxenye yesibili yomthamo we-acrylonitrile yanda kakhulu, ukuhlinzekwa kwempahla noma ukuqhubeka nokukhuphuka.Kodwa-ke, i-ABS kuphela okulindeleke ukuthi ifake ekukhiqizeni amayunithi amasha endaweni engezansi, futhi isidingo sisonke sinomkhawulo.Ngaphansi kokungafani kokuhlinzekwa nokufunwa, ukungqubuzana phakathi kokuhlinzekwa nokufunwa kwe-acrylonitrile kuzoqhubeka nokukhula, futhi kuyoba nzima ukwandisa ukusebenza kwefekthri ngaleso sikhathi.Amabhizinisi anomthamo omkhulu wokukhiqiza azothatha izinyathelo zokunciphisa umthwalo
