I-Mars M Beans yethula ukupakishwa kwamaphepha okuyinhlanganisela ye-PLA engaboli e-China.
Ngo-2022, iMars yethula ushokoledi wokuqala we-M&M opakishwe ephepheni eliyinhlanganisela eyonakalayo e-China. Yenziwe ngezinto eziwohlokayo njengephepha ne-PLA, ithatha indawo yepulasitiki ethambile yendabuko esikhathini esidlule. Ukupakishwa kudlule i-GB/T Indlela yokunquma ka-19277.1 iqinisekise ukuthi ngaphansi kwezimo zokwenziwa komquba wezimboni, ingehlisa izinga elingaphezu kuka-90% ezinyangeni eziyisi-6, futhi izoba amanzi angewona anobuthi bebhayoloji, i-carbon dioxide neminye imikhiqizo ngemuva kokuwohloka. . -
Ukuthunyelwa kwe-PVC yase-China kusalokhu kuphezulu engxenyeni yokuqala yonyaka.
Ngokwezibalo zakamuva zamasiko, ngo-June 2022, umthamo wezwe lami wokungenisa we-PVC ohlanzekile wawungamathani angu-29,900, ukwanda ngo-35.47% kusukela enyangeni edlule kanye nokunyuka konyaka ngo-23.21%; ngo-June 2022, ivolumu yokuthekelisa kwe-PVC yezwe lami emsulwa yayingamathani angama-223,500, Ukwehla kwenyanga nenyanga kwaba ngu-16%, futhi ukunyuka konyaka kwaba ngama-72.50%. Umthamo wokuthunyelwa kwempahla kwamanye amazwe uqhubekile nokugcina izinga eliphezulu, okuye kwanciphisa ukutholakala okuchichimayo emakethe yasekhaya ngokwezinga elithile. -
Iyini i-Polypropylene (PP)?
I-Polypropylene (PP) iyi-thermoplastic eqinile, eqinile, ne-crystalline. Yenziwe nge-propene (noma i-propylene) monomer. Le resin ye-hydrocarbon ewumugqa iyi-polymer elula kakhulu phakathi kwawo wonke amapulasitiki wempahla. I-PP iza njenge-homopolymer noma njenge-copolymer futhi ingakhuliswa kakhulu ngezithasiselo. Ithola ukusetshenziswa emaphaketheni, ezimotweni, ezinhle zabathengi, ezempilo, amafilimu asakazwayo, njll. I-PP isiphenduke into ekhethwayo, ikakhulukazi uma ufuna i-polymer enamandla amakhulu (isb, vs Polyamide) ezinhlelweni zobunjiniyela noma umane ufuna inzuzo yezindleko kumabhodlela okubumba (vs. PET). -
Iyini i-Polyethylene (PE)?
I-Polyethylene (PE) , eyaziwa nangokuthi i-polythene noma i-polyethene, ingenye yepulasitiki esetshenziswa kakhulu emhlabeni. Ama-polyethylenes ngokuvamile anesakhiwo somugqa futhi aziwa njengama-polymers wokwengeza. Ukusetshenziswa okuyinhloko kwalawa ma-polymer okwenziwa kusephaketheni. I-polyethelyne ivame ukusetshenziselwa ukwenza izikhwama zepulasitiki, amabhodlela, amafilimu epulasitiki, iziqukathi, nama-geomembranes. Kuyaphawuleka ukuthi amathani angaphezu kwezigidi eziyi-100 e-polyethene akhiqizwa minyaka yonke ngezinhloso zentengiso nezezimboni. -
Ukuhlaziywa kokusebenza kwemakethe yokuthekelisa ye-PVC yezwe lami engxenyeni yokuqala ka-2022.
Engxenyeni yokuqala ka-2022, imakethe yokuthekelisa ye-PVC yanda unyaka nonyaka. Ngekota yokuqala, ezithintwe ukuwohloka komnotho emhlabeni wonke kanye nalolu bhubhane, izinkampani eziningi zasekhaya ezithumela ngaphandle zibonise ukuthi isidingo samadiski angaphandle sinciphile. Kodwa-ke, kusukela ekuqaleni kukaMeyi, ngokuthuthuka kwesimo sobhubhane kanye nochungechunge lwezinyathelo ezethulwe nguhulumeni waseShayina ukukhuthaza ukusimama komnotho, izinga lokusebenza kwamabhizinisi okukhiqiza asekhaya we-PVC beliphezulu kakhulu, imakethe yokuthekelisa ye-PVC iye yafudumala. , futhi isidingo samadiski angaphandle sinyukile. Inombolo ibonisa ukuthambekela okuthile kokukhula, futhi ukusebenza okuphelele kwemakethe kuye kwaba ngcono uma kuqhathaniswa nesikhathi esidlule. -
I-PVC isetshenziselwa ini?
Ezomnotho, i-polyvinyl chloride eguquguqukayo (i-PVC, noma i-vinyl) isetshenziswa ezinhlobonhlobo zezicelo ezakhiweni nasekwakhiweni, ukunakekelwa kwezempilo, ugesi, izimoto kanye neminye imikhakha, emikhiqizweni esukela kumapayipi namasiding, izikhwama zegazi namashubhu, ukuya kucingo kanye ukufakwa kwekhebula, izingxenye zesistimu ye-windshield nokunye. . -
Iphrojekthi ye-ethylene eyizigidi zamathani kanye nokucwengisiswa kwe-Hainan Refinery isizonikezwa.
Iphrojekthi ye-Hainan Refining kanye neChemical Ethylene Project kanye Nokwakhiwa Kabusha Nokunwetshwa Kwephrojekthi kutholakala e-Yangpu Economic Development Zone, ngokutshalwa kwezimali okuphelele kwama-yuan ayizigidi eziyizinkulungwane ezingama-28. Kuze kube manje, inqubekelaphambili jikelele yokwakha isifinyelele ku-98%. Ngemuva kokuthi iphrojekthi isiqediwe futhi ifakwe ekukhiqizweni, kulindeleke ukuthi iqhube ngaphezulu kwama-yuan ayizigidi eziyizinkulungwane eziyi-100 ezimbonini ezingezansi. I-Olefin Feedstock Diversification kanye ne-High-end Downstream Forum izobanjelwa e-Sanya ngoJulayi 27-28. Ngaphansi kwesimo esisha, ukuthuthukiswa kwamaphrojekthi amakhulu afana ne-PDH, nokuqhekeka kwe-ethane, inkambiso yesikhathi esizayo yobuchwepheshe obusha obufana nowoyela ongahluziwe oqondile kuma-olefin, kanye nesizukulwane esisha samalahle/methanol kuya ku-olefin. . -
I-MIT: Ama-microparticles e-Polylactic-glycolic acid copolymer enza umuthi wokugoma “wokuzithuthukisa”.
Ososayensi base-Massachusetts Institute of Technology (MIT) babika kujenali yakamuva i-Science Advances ukuthi benza umuthi wokuzithuthukisa womthamo owodwa. Ngemuva kokuthi umgomo ujovwe emzimbeni womuntu, ungakhishwa izikhathi eziningi ngaphandle kwesidingo se-booster shot. Umgomo omusha kulindeleke ukuthi usetshenziselwe ukulwa nezifo ezisukela kumvukuzane kuya ku-Covid-19. Kubikwa ukuthi lo mgomo omusha wenziwe ngezinhlayiya ze-poly(lactic-co-glycolic) (PLGA). I-PLGA iyinhlanganisela ye-polymer esebenzayo ewohlokayo, engenabo ubuthi futhi inokuhambisana okuhle kwe-biocompatibility. Igunyaziwe ukuthi isetshenziswe kuma-Implants, sutures, ukulungisa izinto, njll -
I-Yuneng Chemical Company: Ukukhiqizwa kokuqala kwezimboni kwe-polyethylene efuthwayo!
Muva nje, iyunithi ye-LLDPE ye-Polyolefin Center ye-Yuneng Chemical Company ikhiqize ngempumelelo i-DFDA-7042S, umkhiqizo we-polyethylene ofuthwayo. Kuyaqondakala ukuthi umkhiqizo we-polyethylene ofuthwayo ungumkhiqizo osuselwe ekuthuthukisweni okusheshayo kobuchwepheshe bokucubungula okwehla nomfula. Izinto ezikhethekile ze-polyethylene ezinokusebenza kokufafaza phezulu zixazulula inkinga yokusebenza kabi kombala we-polyethylene futhi ine-gloss ephezulu. Umkhiqizo ungasetshenziswa emikhakheni yokuhlobisa nokuvikela, elungele imikhiqizo yezingane, ingaphakathi lemoto, izinto zokupakisha, kanye namathangi amakhulu okugcina izimboni nezolimo, amathoyizi, imigwaqo yokuqapha imigwaqo, njll., futhi ithemba lemakethe likhulu kakhulu. . -
I-Petronas amathani ayizigidi ezingu-1.65 e-polyolefin isizobuyela emakethe yase-Asia!
Ngokwezindaba zakamuva, i-Pengerang e-Johor Bahru, e-Malaysia, isiqale kabusha iyunithi yayo engu-350,000-ton/year linear low-density polyethylene (LLDPE) ngoJulayi 4, kodwa iyunithi ingase ithathe isikhashana Ukufeza ukusebenza okuzinzile. Ngaphandle kwalokho, imboni yayo ye-Spheripol technology engamathani angu-450,000/ngonyaka we-polypropylene (PP), amathani angu-400,000/ngonyaka we-high-density polyethylene (HDPE) kanye nobuchwepheshe be-Spherizone amathani angu-450,000/ngonyaka we-polypropylene (PP) nazo kulindeleke ukuthi zikhule kusukela kule nyanga ukuze ziqale kabusha. Ngokusho kokuhlola kuka-Argus, intengo ye-LLDPE e-Southeast Asia ngaphandle kwentela ngoJulayi 1 ingu-US$1360-1380/ton CFR, futhi intengo yokudweba ngocingo kwe-PP eSoutheast Asia ngoJulayi 1 ingu-US$1270-1300/ton CFR ngaphandle kwentela. . -
Ugwayi ushintshela emaphaketheni epulasitiki angaboli eNdiya.
Ukuvinjelwa kwe-India kwamapulasitiki angu-19 asetshenziswa kanye kuye kwabangela izinguquko embonini yayo kagwayi. Ngaphambi komhla lu-1 kuJulayi, abakhiqizi bakagwayi baseNdiya base beshintshe amaphakethe abo epulasitiki avamile bawafaka epulasitiki abolayo. I-Tobacco Institute of India (TII) ithi amalungu ayo ashintshiwe futhi amapulasitiki angaboli asetshenziswa ahlangabezana nezindinganiso zamazwe ngamazwe, kanye nezinga le-BIS elisanda kukhishwa. Baphinde bathi ukuwohloka kwe-biodegradable yamapulasitiki abolayo aqala ukuhlangana nomhlabathi futhi ngokwemvelo amosheke ekuhlanganiseni umquba ngaphandle kokugcizelela ukuqoqwa kukadoti oqinile kanye nezinhlelo zokugaywa kabusha. -
Ukuhlaziywa Kafushane Kokusebenza Kwemakethe Ye-Calcium Carbide Yasekhaya Engxenyeni Yokuqala Yonyaka.
Engxenyeni yokuqala ka-2022, imakethe yasekhaya ye-calcium carbide ayizange iqhubeke nokuguquguquka okubanzi ngo-2021. Imakethe iyonke yayiseduze nomugqa wezindleko, futhi yayingaphansi kokuguquguquka nokulungiswa ngenxa yomthelela wezinto ezingavuthiwe, ukuhlinzekwa kanye nesidingo. , kanye nezimo ezansi nomfula. Engxenyeni yokuqala yonyaka, kwakungekho umthamo omusha wokunwetshwa wezitshalo ze-PVC ze-calcium carbide zasekhaya, futhi ukwanda kwesidingo semakethe ye-calcium carbide bekunomkhawulo. Kunzima kumabhizinisi e-chlor-alkali athenga i-calcium carbide ukuze agcine umthwalo ozinzile isikhathi eside.
