Nhanganyaya: Nekuenderera mberi kwekusimudzira maindasitiri e acrylic uye ABS resin, kushandiswa kuri pachena kweacrylonitrile kuri kuramba kuchiwedzera munyika yedu.Nekudaro, iyo yakakura yekuwedzera yekugona inoita kuti iyo indasitiri yeacrylonitrile ikozvino iri mumamiriro ekuwedzera uye kudiwa.Pasi pekusawirirana kwekupa uye kudiwa, kupokana pakati pekupa uye kudiwa kweacrylonitrile kuri kuwedzera.
Acrylonitrile inoshandiswa nzvimbo inonyanya kugoverwa mu acrylic fiber, ABS resin (kusanganisira SAN resin), acrylamide (kusanganisira polyacrylamide), nitrile rabha uye maindasitiri emakemikari akanaka.Naizvozvo, East China ndiyo yakanyanya kusangana yezasi ABS, acrylic fiber uye AM/PAM kugadzirwa kwesimba.Kunyangwe huwandu hwezvirimwa zveABS hudiki, huwandu hwekugadzira hwechikamu chimwe nechimwe hwakakura, saka mudziyo weABS pamwe neacrylamide mudziyo unotora kusvika 44% yekushandiswa kweacrylonitrile.Kuchamhembe kwakadziva kumabvazuva kweChina, kunyanya iyo acrylic fiber chirimwa inomiririrwa neJilin kemikari fiber, iyo acrylamide chirimwa muDaqing, uye iyo 80,000-toni ABS unit muJihua inoita 23% yezvinodiwa.MuNorth China, fiber uye amide ndiwo maindasitiri makuru epasi, anoverengera 26%.
Nekuenderera mberi kwekusimudzira kwe acrylic uye ABS resin maindasitiri, iko kushandiswa kweacrylonitrile kwakawedzera nguva dzose munyika yedu.Kunyanya muna 2018, nekuda kwekuchengetedzwa kwepakati kwemidziyo yemumba neyekunze, mutengo weacrylonitrile wakakwira, uye purofiti yakambokwira kusvika 4,000-5,000 yuan/ton, izvo zvakakonzera kukurumidza kuwedzera kwesimba rekugadzira.Naizvozvo, muna 2019, kuwedzera kwacho kwakaunza nguva yekugovaniswa, uye kushandiswa kwayo kwakawedzera zvakanyanya, nekuwedzera panguva imwe chete ye6.3%.Nekudaro, nekusvika kwedenda muna 2020, kukura kwayo kwakadzikira.Nekudaro, iko kushandiswa kuri pachena kweindasitiri yeacrylonitrile kwakawedzera zvakanyanya zvakare muna 2021, kukwira ne3.9% gore negore, kunyanya nekuda kwekudzoreredza kwehupfumi hwenyika uye kuwedzera kwehuwandu hwekutengesa kunze kwenyika.
Pakazara, iyo indasitiri yeacrylonitrile ikozvino iri mumamiriro ekuwedzera, izvo zvakakonzera fekitori yemazuva ano kunyangwe kugadzirwa kwakadzikira, asi musika hausati wanyatso kuvandudzwa, iyo indasitiri inoramba ichirasikirwa nepurofiti.Mukuwedzera, chikamu chechipiri cheacrylonitrile simba idzva rakawedzera zvakanyanya, kugoverwa kwezvinhu kana kuramba kuchikwira.Nekudaro, ABS chete ndiyo inotarisirwa kuisa mukugadzirwa kwezvikamu zvitsva muzasi, uye kudiwa kwese kunogumira.Pasi pekusawirirana kwekupa uye kudiwa, kupesana pakati pekupa uye kudiwa kweacrylonitrile kucharamba kuchiwedzera, uye zvichange zvakaoma kuwedzera kushanda kwefekitari panguva iyoyo.Mabhizinesi ane hukuru hwekugadzira huwandu anotora matanho ekudzikisa mutoro
