Iyini i-PVC compound?
Ama-compound e-PVC asekelwe ekuhlanganisweni kwe-PVC polymer RESIN kanye nezithasiselo ezinikeza ukwakheka okudingekayo ekusetshenzisweni kokugcina (Amapayipi noma Amaphrofayili Aqinile noma Amaphrofayili Aguquguqukayo noma Amashidi). I-compound yakhiwa ngokuhlanganisa izithako ngokuseduze, okuthi kamuva iguqulwe ibe yinto "ehlanganisiwe" ngaphansi kwethonya lokushisa namandla okusika. Kuye ngohlobo lwe-PVC kanye nezithasiselo, i-compound ngaphambi kokufakwa kwe-gel ingaba yimpuphu egeleza ngokukhululeka (eyaziwa ngokuthi ingxube eyomile) noma uketshezi ngesimo se-paste noma isixazululo. Ama-compound e-PVC lapho ehlanganiswa, kusetshenziswa ama-plasticizer, abe izinto eziguquguqukayo, ngokuvamile ezibizwa ngokuthi i-PVC-P. Ama-compound e-PVC lapho ehlanganiswa ngaphandle kwe-plasticizer yezicelo eziqinile abizwa ngokuthi i-PVC-U. I-PVC Compounding ingafingqwa kanje: I-PVC dr... -
Umehluko Phakathi Kwezikhwama ze-BOPP, i-OPP kanye ne-PP.
Imboni yokudla isebenzisa kakhulu ukupakishwa kwepulasitiki ye-BOPP. Izikhwama ze-BOPP kulula ukuziphrinta, ukuzimboza kanye nokuzifaka i-laminate okwenza zifaneleke emikhiqizweni yokupakisha njengemikhiqizo emisha, amaswidi kanye nokudla okulula. Kanye nezikhwama ze-BOPP, i-OPP, kanye ne-PP nazo zisetshenziselwa ukupakishwa. I-Polypropylene iyi-polymer evamile phakathi kwezintathu ezisetshenziselwa ukukhiqiza izikhwama. I-OPP imele i-Oriented Polypropylene, i-BOPP imele i-Biaxially Oriented Polypropylene kanye ne-PP imele i-Polypropylene. Zontathu zihlukile ngesitayela sazo sokwenziwa. I-Polypropylene eyaziwa nangokuthi i-polypropene iyi-polymer ye-thermoplastic semi-crystalline. Iqinile, inamandla futhi inokumelana okukhulu komthelela. Izikhwama ezimile, izikhwama ze-spout kanye nezikhwama ze-ziplock zenziwe nge-polypropylene. Kunzima kakhulu ukuhlukanisa phakathi kwe-OPP, i-BOPP kanye ne-PP plas... -
Ucwaningo Lokusetshenziswa Kokukhanya Okugxilile (i-PLA) kuhlelo Lokukhanyisa lwe-LED.
Ososayensi baseJalimane naseNetherlands bacwaninga ngezinto ezintsha ze-PLA ezinobungani nemvelo. Inhloso ukuthuthukisa izinto ezihlala isikhathi eside zezinhlelo zokusebenza ezibonakalayo njengezibani zezimoto, amalensi, amapulasitiki akhanyayo noma iziqondiso zokukhanya. Okwamanje, le mikhiqizo ngokuvamile yenziwe nge-polycarbonate noma i-PMMA. Ososayensi bafuna ukuthola ipulasitiki esekelwe ku-bio yokwenza izibani zezimoto. Kuvela ukuthi i-polylactic acid iyinto efanelekile. Ngale ndlela, ososayensi baxazulule izinkinga eziningana ezibhekene namapulasitiki endabuko: okokuqala, ukunaka kwabo ezinsizeni ezivuselelekayo kunganciphisa ngempumelelo ingcindezi ebangelwa uwoyela ongahluziwe embonini yamapulasitiki; okwesibili, kunganciphisa ukukhishwa kwe-carbon dioxide; okwesithathu, lokhu Kuhilela ukucabangela impilo yonke yezinto... -
Iphrojekthi ye-ethylene yamathani ayizigidi zaseLuoyang yenze intuthuko entsha!
Ngomhlaka-19 Okthoba, intatheli yezwa kuLuoyang Petrochemical ukuthi iSinopec Group Corporation ibinomhlangano eBeijing muva nje, imema ochwepheshe abavela kumayunithi angaphezu kwe-10 okuhlanganisa i-China Chemical Society, i-China Synthetic Rubber Industry Association, kanye nabamele abafanele ukuthi bakhe iqembu lochwepheshe bokuhlola ukuze bahlole izigidi ze-Luoyang Petrochemical. Umbiko wocwaningo lokusebenziseka kwephrojekthi ye-ethylene engamathani angu-1 uzohlolwa futhi uboniswe ngokuphelele.

Isimo sokusebenza kanye nomkhuba we-polylactic acid (PLA) ezimotweni.
Njengamanje, insimu eyinhloko yokusetshenziswa kwe-polylactic acid yizinto zokupakisha, ezibiza ngaphezu kwama-65% okusetshenziswa okuphelele; kulandelwe izinhlelo zokusebenza ezifana nezitsha zokupheka, imicu/izindwangu ezingalukiwe, kanye nezinto zokunyathelisa ze-3D. IYurophu neNyakatho Melika yizimakethe ezinkulu ze-PLA, kanti i-Asia Pacific izoba enye yezimakethe ezikhula ngokushesha emhlabeni njengoba isidingo se-PLA siqhubeka nokukhula emazweni afana neShayina, iJapan, iNingizimu Korea, iNdiya kanye neThailand. Ngokombono wemodi yokusetshenziswa, ngenxa yezakhiwo zayo ezinhle zemishini nezomzimba, i-polylactic acid ifanelekela ukubumba i-extrusion, ukubumba umjovo, ukubumba i-extrusion blow, ukuphotha, ukwenza i-foam kanye nezinye izinqubo ezinkulu zokucubungula ipulasitiki, futhi ingenziwa ibe amafilimu namashidi. , i-fiber, ucingo, i-powder kanye... -
I-INEOS Imemezela Ukwandiswa 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 saseLillo echwebeni lase-Antwerp ukuze amandla ayo akhona akwazi ukukhiqiza amazinga e-polyethylene ephezulu (i-HDPE) alinganayo noma amabili ukuze ihlangabezane nesidingo esinamandla sezicelo eziphezulu emakethe. I-INEOS izosebenzisa ulwazi lwayo ukuze iqinise isikhundla sayo esiphambili njengomhlinzeki emakethe yamapayipi okucindezela okuphezulu, futhi lokhu kutshalwa kwezimali kuzokwenza i-INEOS ihlangabezane nesidingo esikhulayo sezicelo ezibalulekile emnothweni omusha wamandla, njenge: ezokuthutha Amanethiwekhi amapayipi acindezelwe e-hydrogen; amanethiwekhi amapayipi ekhebula angaphansi komhlaba ahamba ibanga elide amapulazi omoya kanye nezinye izinhlobo zokuthutha amandla avuselelekayo; ingqalasizinda kagesi; a... -
Isidingo se-PVC somhlaba wonke kanye namanani kokubili kuyehla.
Kusukela ngo-2021, isidingo somhlaba wonke se-polyvinyl chloride (PVC) sibone ukwenyuka okukhulu okungakaze kubonwe kusukela enkingeni yezezimali yomhlaba wonke ka-2008. Kodwa maphakathi no-2022, isidingo se-PVC sibanda ngokushesha futhi amanani ehla ngenxa yokwenyuka 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 emhlabeni wonke njengoba umsebenzi wokwakha wehla.

Ukuqhathaniswa kwe-LLDPE ne-LDPE.
I-polyethylene eqondile ephansi, ehlukile ngokwesakhiwo ku-polyethylene ejwayelekile ephansi ephansi, ngoba azikho amagatsha eketanga elide. Ukulingana kwe-LLDPE kuncike ezinqubweni ezahlukene zokukhiqiza nokucubungula ze-LLDPE ne-LDPE. I-LLDPE ivame ukwakheka yi-copolymerization ye-ethylene nama-olefin aphezulu e-alpha njenge-butene, i-hexene noma i-octene ekushiseni okuphansi kanye nengcindezi. I-polymer ye-LLDPE ekhiqizwa yinqubo ye-copolymerization inokusatshalaliswa kwesisindo sama-molecule okuncane kune-LDPE ejwayelekile, futhi ngesikhathi esifanayo inesakhiwo esiqondile esenza ibe nezakhiwo ezihlukile ze-rheological. Izakhiwo zokugeleza kokuncibilika Izici zokugeleza kokuncibilika kwe-LLDPE zivumelaniswa nezidingo zenqubo entsha, ikakhulukazi inqubo yokukhipha ifilimu, engakhiqiza i-LL... -
I-Jinan Refinery iphumelele ukuthuthukisa impahla ekhethekile ye-geotextile polypropylene.
Muva nje, iJinan Refining and Chemical Company iphumelele ukuthuthukisa i-YU18D, into ekhethekile ye-geotextile polypropylene (PP), esetshenziswa njengezinto zokusetshenziswa zomugqa wokuqala wokukhiqiza i-PP filament geotextile wamamitha ayi-6 emhlabeni, ongathatha indawo yemikhiqizo efanayo engenisiwe. Kuyaqondakala ukuthi i-PP filament geotextile ebanzi kakhulu imelana nokugqwala kwe-asidi ne-alkali, futhi inamandla amakhulu okudabuka kanye namandla okudonseka.
