Horudhac: Iyadoo horumarinta joogtada ah ee warshadaha acrylic iyo ABS resin, isticmaalka muuqda ee acrylonitrile ayaa si joogto ah ugu kordhaya dalkeena.Si kastaba ha noqotee, balaadhinta ballaaran ee awoodda ayaa ka dhigaysa warshadaha acrylonitrile hadda inay ku jiraan xaaladda xad-dhaafka ah iyo baahida.Marka la eego is-waafajinta baahida iyo saadka, iska horimaadka u dhexeeya saadka iyo baahida acrylonitrile ayaa sii kordhaya.
Meelaha isticmaalka acrylonitrile waxaa inta badan loo qaybiyaa fiber akril, resin ABS (oo ay ku jiraan SAN resin), acrylamide (oo ay ku jiraan polyacrylamide), caag nitrile ah iyo warshado kiimiko oo wanaagsan.Sidaa darteed, Bariga Shiinaha waa diiradda ugu weyn ee ABS, fiber acrylic iyo awoodda wax soo saarka AM / PAM.In kasta oo tirada dhirta ABS ay yar tahay, awoodda wax-soo-saarka unug kastaa waa weyn tahay, markaa aaladda ABS iyo aaladda acrylamide waxay xisaabisaa ilaa 44% isticmaalka acrylonitrile.Waqooyi-bari Shiinaha, badiyaa warshadda akril-fiberka ah ee ay matalayso Jilin kiimikaad fiber, warshadda acrylamide ee Daqing, iyo unugga 80,000-ton ee ABS ee Jihua ayaa qiyaastii 23% ka ah baahida.Waqooyiga Shiinaha, fiber iyo amide ayaa ah warshadaha ugu muhiimsan, oo xisaabiya 26%.
Iyadoo horumarinta joogtada ah ee warshadaha akril iyo ABS resin, isticmaalka muuqda ee acrylonitrile ayaa si joogto ah ugu kordhay dalkeena.Gaar ahaan 2018, sababtoo ah dayactirka dhexe ee qalabka gudaha iyo dibedda, qiimaha acrylonitrile ayaa kor u kacay, faa'iidada ayaa mar ahayd ilaa 4,000-5,000 yuan / ton, taas oo kicisay balaadhinta degdega ah ee awoodda wax soo saarka.Sidaa darteed, sanadka 2019, balaadhintu waxay keentay xilli saami qaybsi, isticmaalkeeda muuqatana aad buu u kordhay, iyada oo isla markaaba korodhay 6.3%.Si kastaba ha ahaatee, imaatinka masiibada ee 2020, heerka kobaca ayaa hoos u dhacay.Si kastaba ha ahaatee, isticmaalka cad ee warshadaha acrylonitrile ayaa si aad ah u kordhay mar kale sanadka 2021, ilaa 3.9% sannadkii, inta badan sababtoo ah soo kabashada dhaqaalaha adduunka iyo korodhka mugga dhoofinta gudaha.
Guud ahaan, warshadaha acrylonitrile ayaa hadda ku jira xaalad xad dhaaf ah, taas oo sababtay warshadda hadda jirta xitaa haddii wax soo saarka la yareeyo, laakiin suuqa ayaan weli si weyn u hagaajin, warshaduhu waxay sii wadaan inay lumiyaan faa'iidada.Intaa waxaa dheer, qeybtii labaad ee acrylonitrile awoodda cusub ayaa si aad ah u korodhay, sahayda badeecadaha ama kor u kaca.Si kastaba ha ahaatee, kaliya ABS ayaa la filayaa inay soo saarto wax soo saarka cutubyo cusub oo ka mid ah kuwa hoose, iyo baahida guud waa xaddidan tahay.Marka la eego is-waafajinta baahida iyo saadka, iska horimaadka u dhexeeya sahayda iyo baahida acrylonitrile ayaa sii wadi doonta inay kordhiso, wayna adkaan doontaa in la kordhiyo hawlgalka warshadda wakhtigaas.Shirkadaha leh awoodda wax-soo-saarka weyn waxay qaadi doonaan tallaabooyin ay ku yareynayaan culeyska
