Intshayelelo: Ngophuhliso oluqhubekayo lwe-acrylic kunye ne-ABS resin industries, ukusetyenziswa okubonakalayo kwe-acrylonitrile kukhula rhoqo kwilizwe lethu.Nangona kunjalo, ukwandiswa okukhulu kwamandla kwenza ukuba imboni ye-acrylonitrile ngoku ikwimeko yokugqithiswa kunye nokufunwa.Ngaphantsi kokungafani kokubonelela kunye nemfuno, ukuchasana phakathi kokunikezelwa kunye nemfuno ye-acrylonitrile iyanda.
Iindawo zokusetyenziswa kwe-Acrylonitrile zisasazwa kakhulu kwi-acrylic fiber, i-ABS resin (kubandakanywa ne-SAN resin), i-acrylamide (kuquka i-polyacrylamide), irabha ye-nitrile kunye namashishini amachiza afanelekileyo.Ngoko ke, i-East China iyona ingqwalasela ephambili ye-ABS ephantsi, i-acrylic fiber kunye ne-AM / PAM umthamo wokuvelisa.Nangona inani lezityalo ze-ABS lincinci, umthamo wemveliso weyunithi nganye mkhulu, ngoko ke isixhobo se-ABS kunye neakhawunti yesixhobo se-acrylamide ukuya kuthi ga kwi-44% yokusetyenziswa kwe-acrylonitrile.KuMntla-mpuma weChina, ubukhulu becala isityalo se-acrylic fiber esimelwe yi-Jilin chemical fiber, isityalo se-acrylamide e-Daqing, kunye neyunithi ye-ABS ye-80,000 ye-ABS kwi-akhawunti ye-Jihua malunga ne-23% yemfuno.Emantla eTshayina, i-fiber kunye ne-amide zezona mizi-mveliso zisezantsi, zibalelwa kwi-26%.
Ngophuhliso oluqhubekayo lwe-acrylic kunye ne-ABS resin industries, ukusetyenziswa okubonakalayo kwe-acrylonitrile kwanda rhoqo kwilizwe lethu.Ngokukodwa ngo-2018, ngenxa yokugcinwa kwendawo ephakathi kwezixhobo zasekhaya nezangaphandle, ixabiso le-acrylonitrile liye lanyuka, kwaye inzuzo yayikhe yafikelela kwi-4,000-5,000 yuan / toni, eyabangela ukwanda ngokukhawuleza kwamandla okuvelisa.Ke ngoko, ngo-2019, ukwanda kungenise ixesha lezabelo, kwaye ukusetyenziswa kwayo okubonakalayo kunyuke kakhulu, ngokunyuka ngaxeshanye nge-6.3%.Nangona kunjalo, ngokufika kobhubhane ngo-2020, izinga lokukhula lehla.Nangona kunjalo, ukusetyenziswa okubonakalayo kweshishini le-acrylonitrile kunyuke kakhulu kwakhona ngo-2021, kunyuke nge-3.9% unyaka nonyaka, ikakhulu ngenxa yokuchacha koqoqosho lwehlabathi kunye nokunyuka komthamo wangaphakathi wokuthengisa ngaphandle.
Ngokubanzi, imboni ye-acrylonitrile ngoku ikwimeko yokugqithisa, okuye kwabangela ukuba i-factory yangoku nangona imveliso iyancipha, kodwa imarike ayikaphuculwa kakhulu, imboni iyaqhubeka ilahlekelwa yinzuzo.Ukongezelela, isiqingatha sesibini se-acrylonitrile umthamo omtsha unyuke kakhulu, ukunikezelwa kwempahla okanye ukuqhubeka nokunyuka.Nangona kunjalo, yi-ABS kuphela ekulindeleke ukuba ifakwe kwimveliso yeeyunithi ezintsha kumazantsi omlambo, kwaye imfuno iyonke ilinganiselwe.Ngaphantsi kokungafani kokubonelela kunye nemfuno, ukuchasana phakathi kokunikezelwa kunye nemfuno ye-acrylonitrile kuya kuqhubeka nokunyuka, kwaye kuya kuba nzima ukunyusa ukusebenza kwefektri ngelo xesha.Amashishini anomthamo omkhulu wemveliso aya kuthatha amanyathelo okunciphisa umthwalo
