Julaay 1, 2022, xaflada bilawga wejiga koowaad ee 300,000 tanmethyl methacrylate(halkan ka dib waxaa loo yaqaan methyl methacrylate) Mashruuca MMA ee Henan Zhongkepu Raw iyo New Materials Co., Ltd. ayaa lagu qabtay Puyang Dhaqaalaha iyo Horumarinta Tignoolajiyada, calaamadaynta codsiga ee set cusub ee cusub ee qalabka ionic dareere catalytic ethylene MMA technology si madax-bannaan u horumariyo by CAS iyo Zhongyuan Dahua.Tani sidoo kale waa warshaddii ugu horreysay ee ethylene MMA ee lagu daabacay Shiinaha.Haddii qalabka si guul leh loo geliyo wax soo saarka, waxay gaari doontaa horumar xagga wax soo saarka ethylene MMA ee Shiinaha, taas oo saameyn aad u muhiim ah ku leh warshadaha MMA.
Unugga labaad ee MMA ee habka ethylene ee Shiinaha ayaa laga yaabaa in lagu shaaciyo Shandong.Markii hore waxaa la filayaa in la soo saaro wax soo saar ku dhawaad ​​2024, waxayna hadda ku jirtaa marxaladda ansixinta horudhaca ah.Haddii cutubku run yahay, waxay noqon doontaa qaybta labaad ee MMA ee habka ethylene ee Shiinaha, taas oo muhiimad weyn u leh kala-duwanaanta habka wax soo saarka MMA ee Shiinaha iyo horumarinta warshadaha kiimikada ee Shiinaha.
Marka loo eego xogta ku habboon, waxaa jira hababka soo socda ee wax soo saarka MMA ee Shiinaha: Habka C4, habka ACH, habka ACH oo la hagaajiyay, habka BASF ethylene iyo habka Lucite ethylene.Caalami ahaan, hababkan wax soo saarku waxay leeyihiin qalabyo warshadeed.Shiinaha, sharciga C4 iyo sharciga ACH ayaa la warshadeeyay, halka sharciga ethylene aan si buuxda loo warshadayn.
Waa maxay sababta warshadaha kiimikada Shiinaha ay u balaarinayaan warshadeeda ethylene MMA?Qiimaha wax-soo-saarka MMA ee ay soo saarto habka ethylene ma yahay mid tartan ah?
Marka hore, warshadda ethylene MMA waxay ka abuurtay Shiinaha meel bannaan waxayna leedahay heer tignoolajiyada wax soo saarka sare.Marka loo eego sahanka, waxaa jira laba qaybood oo kaliya oo ah unugyada ethylene MMA adduunka, kuwaas oo ku kala yaal Yurub iyo Waqooyiga Ameerika siday u kala horreeyaan.Xaaladaha farsamo ee unugyada ethylene MMA waa kuwo fudud.Heerka isticmaalka atomigu waa in ka badan 64%, wax-soo-saarkuna wuu ka sarreeyaa noocyada kale ee habka.BASF iyo Lucite waxay sameeyeen cilmi-baaris farsamo iyo horumarinta qalabka MMA ee geeddi-socodka ethylene goor hore, waxayna ku guuleysteen warshadaynta.
Unugga MMA ee geeddi-socodka ethylene kama qaybqaataan alaabta ceeriin ee acidic ah, taas oo sidoo kale keenaysa daxalka hoose ee qalabka, habka wax-soo-saarka deegaanka-saaxiibtinimo, iyo muddada dheer ee hawlgalka guud iyo wareegga.Xaaladdan oo kale, qiimaha qiimo dhimista cutubka MMA ee habka ethylene inta lagu jiro hawlgalka ayaa ka hooseeya kan hababka kale.
Qalabka Ethylene MMA wuxuu kaloo leeyahay faa'iidooyin.Marka hore, tas-hiilaadka taageerada dhirta ethylene ayaa loo baahan yahay, kaas oo ethylene inta badan ay soo saarto dhirta isku dhafan, sidaas darteed taageerada horumarinta shirkadaha isku dhafan ayaa loo baahan yahay.Haddii ethylene la iibsado, dhaqaaluhu wuu liitaa.Marka labaad, waxaa jira laba qaybood oo kaliya oo ah qalabka ethylene MMA adduunka.Mashaariicda Shiinaha ee la dhisayo waxay adeegsadaan tignoolajiyada Akadeemiyada Sayniska ee Shiinaha, shirkadaha kalena si fudud oo waxtar leh uma heli karaan farsamada.Saddexaad, qalabka MMA ee geeddi-socodka ethylene wuxuu leeyahay geedi socod dheer, miisaan maalgashi oo ballaaran, qadar badan oo koloriin ah oo ay ku jiraan biyaha wasakhda ah ayaa la soo saari doonaa habka wax soo saarka, iyo kharashka daaweynta ee saddexda qashin ayaa sarreeya.
Marka labaad, tartanka kharashka ee cutubka MMA wuxuu inta badan ka yimaadaa ethylene taageerta, halka ethylene dibadda ah aysan lahayn faa'iido tartan oo muuqda.Marka loo eego baaritaanka, unugga MMA ee habka ethylene waa 0.4294 tan oo ethylene ah, 0.387 tan oo methanol ah, 661.35 Nm ³ gaaska synthetic, 1.0578 tan oo koloriin ceyriin ah ayaa lagu soo saaraa falcelinta co, mana jirto wax soo saarka methacrylic acid. .
Marka loo eego xogta ku habboon ee ay soo saartay Shanghai Yunsheng Chemical Technology Co., Ltd., qiimaha MMA ee habka ethylene wuxuu ku saabsan yahay 12000 yuan / ton marka ethylene uu yahay 8100 yuan / ton, methanol waa 2140 yuan / ton, gaaska synthetic waa 1.95 yuan / mitir kuyuubik, koloriin cayriinna waa 600 yuan/ton.Marka la barbardhigo isla muddadaas, kharashka sharciga ee habka C4 iyo habka ACH waa sarreeyaa.Sidaa darteed, marka loo eego xaaladaha suuqa ee hadda jira, ethylene MMA ma laha tartan dhaqaale oo muuqda.
Si kastaba ha ahaatee, soo saarista MMA ee habka ethylene waxay u badan tahay inay la mid tahay ilaha ethylene.Ethylene asal ahaan waxay ka timid dildilaaca nafta, isku-dhafka dhuxusha, iwm. Xaaladdan oo kale, tartanka wax soo saarka MMA ee habka ethylene ayaa inta badan saameyn doonta kharashka alaabta ceeriin ee ethylene.Haddii alaabta ceyriinka ah ee ethylene ay iskeed isu keento, waa in lagu xisaabiyaa iyadoo lagu salaynayo qiimaha ethylene, taasoo si weyn u wanaajin doonta tartanka qiimaha ethylene MMA.
Seddexaad, ethylene MMA waxay isticmaashaa koloriin badan, qiimaha iyo xidhiidhka taageerada koloriinta ayaa sidoo kale go'aamin doona furaha tartanka qiimaha ethylene MMA.Marka loo eego hababka wax soo saarka ee BASF iyo Lucite, labadan habraac waxay u baahan yihiin inay cunaan xaddi badan oo koloriin ah.Haddii koloriintu leedahay xidhiidh taageero oo u gaar ah, kharashka koloriintu uma baahna in la tixgeliyo, taas oo si weyn u wanaajin doonta tartanka qiimaha ethylene MMA.
Waqtigan xaadirka ah, ethylene MMA ayaa soo jiidatay dareenka inta badan sababtoo ah tartanka qiimaha wax soo saarka iyo jawiga hawlgelinta ee cutubka.Intaa waxaa dheer, shuruudaha lagu taageerayo alaabta ceeriin waxay sidoo kale u hoggaansamaan habka horumarinta hadda ee warshadaha kiimikada ee Shiinaha.Haddii shirkadu ay taageerto ethylene, koloriin iyo gaaska synthesis, markaa ethylene MMA waxa laga yaabaa inay noqoto qaabka wax soo saarka MMA ugu qiimaha badan.Waqtigan xaadirka ah, qaabka horumarinta warshadaha kiimikada ee Shiinaha ayaa inta badan ah tas-hiilaad taageero oo dhammaystiran.Isbeddelkan, habka ethylene ee ku habboon ethylene MMA wuxuu noqon karaa diiradda warshadaha.
