Pa Julayi 1, 2022, Mwambo wamawu a gawo loyamba la 300,000methyl methacrylate. Ilinso ethylene Mma Brat lofalitsidwa ku China. Ngati zida zikuyende bwino, zidzakwaniritsa bwino Ethylene, zomwe zimakhudza kwambiri malonda a mma.
Chigawo chachiwiri cha Mma a Ethylene ku China chitha kufalitsidwa mu shandong. Amayembekezeka kupangidwa pafupifupi 2024, ndipo pakadali pano munthawi yovomerezeka. Ngati gawoli ndi loona, lidzakhala yachiwiri ya Mmail of Ethylene ku China, yomwe ndiyofunika kwambiri kusiyanasiyana kwa ntchito ku China ndikukula kwa makampani opanga mankhwala.
Malinga ndi deta yoyenera, pali njira zotsatirazi ku China: Njira ya C4, njira ya ACH, kukonza njira ya aas, basf ethylene njira. Padziko lonse lapansi, njira zopangira izi zimakhala ndi makiyitoni akufakitale. Ku China, lamulo la CARIAND ndipo Lamulo la AY likhala lotukuka, pomwe Lamulo la Ethyne silinatukule bwino.
Kodi ndichifukwa chiyani makampani opanga mankhwala a China ndi akukulitsa chomera chake cha Ethlene? Kodi mtengo wopanga wa MMA wopangidwa ndi njira ya ethynene yopikisana?
Choyamba, chomera cha Ethylene Mma adapanga zopanda pake ku China ndipo ali ndi ukadaulo waluso kwambiri. Malinga ndi kafukufukuyu, pali zigawo ziwiri zokha za mayunitsi a ethylene padziko lapansi, omwe ali ku Europe ndi North America motsatana. Mitundu ya ma ethylene mma ndi yosavuta. Kugwiritsa ntchito kwa atomiki kumapitilira 64%, ndipo zokolola ndizokwera kuposa mitundu ina. Basf ndi Lucii atenga kafukufuku ndi chitukuko cha zida za Mma kwa Ethylene molawirira kwambiri, ndipo adakwaniritsa mafakitale.
Gulu la mma United Nations silitenga nawo mbali m'magawo opangira ma acidic, omwe amachititsanso chilengedwe chochepa, malo okhala okonda kupanga, komanso nthawi yayitali yogwira ntchito. Pankhaniyi, mtengo wotsika mtengo wa Mma Unit mu Ethylene njira yogwirira ntchito ndiyotsika kuposa njira zina.
Zida za Ethyne MMAnso pali zovuta. Choyamba, malo othandizira a ethylene amafunikira, momwe Ethylene amapangidwa kwambiri ndi mbewu zomwe zimaphatikizidwa, kotero kuthandizira chitukuko chabizinesi zophatikizika ndikofunikira. Ngati Ethylene wagulidwa, zachuma ndi wosauka. Chachiwiri, pali zigawo ziwiri zokha za zida za Ethynene padziko lapansi. Ntchito za China zomwe zikumanga muukadaulo za Chitchalitchi cha China Chachine, ndipo mabizinesi ena sangathe kupeza ukadaulo. Chachitatu, zida za mma wa ethylene za njira yayitali, kuchuluka kwakukulu, kuchuluka kwakukulu kwa chlorine wokhala ndi zinyalala kumapangidwa popanga, ndipo mankhwalawa a mafomu atatuwo ndi okwera.
Chachiwiri, mpikisano wa mtengo wa mma unit makamaka umachokera ku Ethylene wothandizira, pomwe Ethylene wakunja alibe mwayi wampikisano. Malinga ndi kafukufukuyu, gulu la mma unit of Ethylene la matani 0,4294 a Ethylene, 0,387 matani a methanol, 661.35 NMOR Chlorine, 1.575 NMOR Chlorine yopangidwa, ndipo palibe chinthu chochita cha Methacrylic muzopanga.
Malinga ndi zomwe Shanghai Yunsheng Micsulogy Co., Ltd., mtengo wa mma " Poyerekeza ndi nthawi yomweyo, ndalama zamtengo wapatali za njira ya c4 ndi njira za As ndizokwera. Chifukwa chake, malinga ndi msika womwe uli pano, ethylene mma alibe chiwonetsero chachuma chodziwikiratu.
Komabe, kupanga kwa mma mwa njira ya ethynene kumayenera kufanana ndi ethylene zothandizira. Ethylene makamaka wochokera ku Nahtha akulimbana, kayendedwe ka malasha, ndi zina mwa izi, mpikisano wa kupanga kwa mma umakhudzidwa kwambiri ndi mtengo wa ma ethylene ophika. Ngati zinthu za ethylene zimadzipatsa zomwe zimaperekedwa, ziyenera kuwerengedwa malinga ndi mtengo wa Ethylene, zomwe zidzasinthiratu mpikisano wa Ethylene MMA.
Chachitatu, a Ethylene Mma amadya chlorine yambiri, ndipo mtengo wothandizira wa chlorine udzadziwitsanso chinsinsi cha mpikisano wa Ethylene MMA. Malinga ndi njira zopangira basef ndi Lucite, njira zonsezi zimafunikira kudya chlorine yambiri. Ngati chlorine ali ndi ubale wake wothandiza, mtengo wa chlorine sufunika kulingaliridwa, zomwe zimapangitsa kuti mpikisano wa ethyneme Mma.
Pakadali pano, a Ethylene mma wakopa chidwi chachikulu chifukwa cha mpikisano wa ndalama zopanga ndi malo ofatsa a unit. Kuphatikiza apo, zofunikira zothandiziranso zopangira zimagwirizananso ndi njira yofotokozera za mankhwala a China. Ngati bizinesiyo ikuthandizira Ethylene, chlorine ndi synthesis gasi, ndiye ethylene mma akhoza kukhala njira yotsika mtengo kwambiri ya MMA. Pakadali pano, njira yopangira mankhwala ku China imakhala malo othandizira. Pansi pa izi, njira ya ethynene yofananira ndi Ethylene Mma atha kukhala cholinga cha malonda.
