Ucwaningo Lokusebenza Lokugxilisa Ukukhanya (PLA) ku-LED Lighting System.
Ososayensi abavela eJalimane nase-Netherlands bacwaninga ngezinto ezintsha ze-PLA ezihambisana nemvelo. Inhloso ukuthuthukisa izinto ezisimeme zezinhlelo zokusebenza ze-optical ezifana nezibani zangaphambili zezimoto, amalensi, amapulasitiki akhanyayo noma iziqondiso ezikhanyayo. Okwamanje, le mikhiqizo ngokuvamile yenziwe nge-polycarbonate noma i-PMMA. Ososayensi bafuna ukuthola ipulasitiki esekwe ku-bio yokwenza izibani zemoto. Kuvela ukuthi i-polylactic acid iyinto efanelekile yekhandidethi. Ngale ndlela, ososayensi baye baxazulula izinkinga eziningana ezibhekene namapulasitiki endabuko: okokuqala, ukunaka izinsiza ezivuselelekayo kunganciphisa ngokuphumelelayo ingcindezi ebangelwa uwoyela ongahluziwe embonini yepulasitiki; okwesibili, kunganciphisa ukukhishwa kwesikhutha; okwesithathu, lokhu Kubandakanya ukucutshungulwa kwayo yonke impilo yezinto ezibonakalayo c... -
I-Luoyang amathani ayizigidi zephrojekthi ye-ethylene yenza inqubekelaphambili entsha!
Ngo-Okthoba 19, intatheli yathola kuLuoyang Petrochemical ukuthi iSinopec Group Corporation ibambe umhlangano eBeijing muva nje, imema ochwepheshe abavela kumayunithi angaphezu kwe-10 okuhlanganisa i-China Chemical Society, i-China Synthetic Rubber Industry Association, kanye nabameleli abafanelekile ukuba bakhe iqembu lochwepheshe bokuhlola elizohlola izigidi zeLuoyang Petrochemical.

Isimo sohlelo lokusebenza kanye nokuthambekela kwe-polylactic acid (PLA) ezimotweni.
Njengamanje, insimu eyinhloko yokusetshenziswa kwe-polylactic acid yizinto zokupakisha, ezibalwa ngaphezu kwe-65% yokusetshenziswa okuphelele; kulandelwa izinhlelo zokusebenza ezifana nezitsha zokudla, amafayibha/izindwangu ezingalukiwe, nezinto zokuphrinta ze-3D. IYurophu neNyakatho Melika yizimakethe ezinkulu ze-PLA, kanti i-Asia Pacific izoba enye yezimakethe ezikhula ngokushesha emhlabeni njengoba isidingo se-PLA siqhubeka sikhula emazweni afana neChina, Japan, South Korea, India kanye neThailand. Ngokombono wemodi yesicelo, ngenxa yezakhiwo zayo ezinhle zemishini nezomzimba, i-polylactic acid ifaneleka ukubunjwa kwe-extrusion, ukubunjwa komjovo, ukubunjwa kwe-extrusion blow, ukuphotha, ukugwebu kanye nezinye izinqubo ezinkulu zokucubungula ipulasitiki, futhi ingenziwa ibe amafilimu namashidi. , i-fiber, ucingo, impushana kanye ne-o... -
I-INEOS Imemezela Ukunwetshwa Kwekhono Le-Olefin Lokukhiqiza I-HDPE.
Muva nje, i-INEOS O&P Europe imemezele ukuthi izotshala ama-euro ayizigidi ezingama-30 (cishe ama-yuan ayizigidi ezingama-220) ukuguqula isitshalo sayo i-Lillo ethekwini lase-Antwerp ukuze umthamo wayo okhona ukwazi ukukhiqiza amamaki e-unimodal noma ama-bimodal e-high-density polyethylene (HDPE) Ukuhlangabezana nesidingo esinamandla sezicelo ezisezingeni eliphezulu emakethe. I-INEOS izosebenzisa ulwazi lwayo lokuqinisa isikhundla sayo sokuhola njengomphakeli emakethe yamapayipi okucindezela okuphezulu, futhi lokhu kutshalwa kwezimali kuzokwenza i-INEOS ihlangabezane nesidingo esikhulayo sezicelo ezibalulekile emnothweni omusha wamandla, njengokuthi: ezokuthutha Amanethiwekhi wamapayipi acindezelwe we-hydrogen; amapayipi amapayipi ahamba ibanga elide angaphansi komhlaba kumapulazi omoya kanye nezinye izinhlobo zokuthutha amandla avuselelekayo; ingqalasizinda yokufaka ugesi; a... -
Isidingo se-PVC yomhlaba wonke nezintengo zombili ziyehla.
Kusukela ngo-2021, isidingo somhlaba wonke se-polyvinyl chloride (PVC) sibone ukukhuphuka okubukhali okungakaze kubonwe kusukela ngenhlekelele yezimali yomhlaba yango-2008. Kodwa maphakathi no-2022, isidingo se-PVC siphola ngokushesha futhi izintengo ziyehla ngenxa yokukhuphuka kwamazinga enzalo kanye nokwehla kwamandla emali okuphezulu kakhulu emashumini eminyaka. Ngo-2020, isidingo se-PVC resin, esetshenziselwa ukwenza amapayipi, amaphrofayili eminyango namafasitela, i-vinyl siding neminye imikhiqizo, sehle kakhulu ezinyangeni zokuqala zokuqubuka kwe-COVID-19 yomhlaba wonke njengoba umsebenzi wokwakha wehla. Idatha ye-S&P Global Commodity Insights ibonisa ukuthi emasontweni ayisithupha kuya ekupheleni kuka-April 2020, intengo ye-PVC ethunyelwe isuka e-United States yehle ngo-39%, kuyilapho intengo ye-PVC e-Asia naseTurkey nayo yehle ngo-25% yaya ku-31%. Izintengo ze-PVC kanye nesidingo zikhuphuke ngokushesha maphakathi no-2020, ngomfutho oqinile wokukhula ngokusebenzisa... -
