I-Sinopec, i-PetroChina nabanye bafake izicelo ngokuzithandela zokususa ohlwini ezitokisini zase-US !
Ngemva kokukhishwa ohlwini kwe-CNOOC e-New York Stock Exchange, izindaba zakamuva ukuthi ntambama ngo-Agasti 12, iPetroChina neSinopec bakhipha izimemezelo ngokulandelana ukuthi bahlela ukukhipha ama-American Depositary Shares e-New York Stock Exchange. Ngaphezu kwalokho, iSinopec Shanghai Petrochemical, i-China Life Insurance, ne-Aluminium Corporation yaseChina nazo zikhiphe izimemezelo ngokulandelana zithi zihlose ukukhipha amasheya ediphozithi aseMelika e-New York Stock Exchange. Ngokwezimemezelo zezinkampani ezifanele, lezi zinkampani zithobele ngokuqinile imithetho yemakethe yemali yase-US kanye nezidingo zokulawula kusukela zavela esidlangalaleni e-United States, futhi ukukhetha kokukhipha ohlwini kwenziwe ngenxa yebhizinisi labo. -
Kwethulwe ifloss yokuqala ye-PHA emhlabeni !
NgoMeyi 23, uhlobo lwe-American dental floss i-Plackers®, yethula i-EcoChoice Compostable Floss, ifloss yamazinyo eqhubekayo engabola ngo-100% endaweni evundile yasekhaya. I-EcoChoice Compostable Floss ivela ku-PHA ye-Danimer Scientific, i-biopolymer ethathwe kuwoyela we-canola, i-silika yemvelo kanye namakhoba kakhukhunathi. I-compostable floss entsha ihambisana nephothifoliyo yamazinyo eqhubekayo ye-EcoChoice. Azigcini nje ngokuhlinzeka ngesidingo sokufloss, kodwa futhi zinciphisa amathuba okuthi amapulasitiki angene olwandle nasezindaweni zokulahla imfucumfucu. -
Ukuhlaziywa Kwesimo Sokuthuthukiswa Kwemboni ye-PVC eNyakatho Melika.
INyakatho Melika iyindawo yesibili ngobukhulu emhlabeni yokukhiqiza i-PVC. Ngo-2020, ukukhiqizwa kwe-PVC eNyakatho Melika kuzoba amathani ayizigidi ezingu-7.16, okubalelwa ku-16% wokukhiqizwa kwe-PVC emhlabeni jikelele. Ngokuzayo, ukukhiqizwa kwe-PVC eNyakatho Melika kuzoqhubeka nokugcina umkhuba okhuphukayo. INyakatho Melika ingumkhiqizi omkhulu we-PVC emhlabeni wonke, ibalwa ku-33% wohwebo lokuthekelisa lwe-PVC emhlabeni jikelele. Ithonywe ukutholakala okwanele eNyakatho Melika ngokwayo, umthamo wokungenisa ngeke ukhuphuke kakhulu esikhathini esizayo. Ngo-2020, ukusetshenziswa kwePVC eNyakatho Melika cishe kungamathani ayizigidi ezi-5.11, cishe ama-82% awo atholakala e-United States. Ukusetshenziswa kwePVC yaseNyakatho Melika ikakhulukazi kuvela ekuthuthukisweni kwemakethe yokwakha. -
Isetshenziselwa yiphi i-HDPE?
I-HDPE isetshenziswa emikhiqizweni nasekupakishweni okufana nezimbiza zobisi, amabhodlela okuhlanza, amabhavu e-margarine, izitsha zikadoti namapayipi amanzi. Kumashubhu anobude obuhlukahlukene , i-HDPE isetshenziswa esikhundleni samashubhu odaka ekhadibhodi ahlinzekiwe ngezizathu ezimbili eziyinhloko. Okokuqala, iphephe kakhulu kunamashubhu ekhadibhodi anikeziwe ngoba uma igobolondo belingangasebenzi kahle futhi liqhume ngaphakathi kweshubhu le-HDPE, ishubhu ngeke liphihlize. Isizathu sesibili ukuthi angasetshenziswa kabusha okuvumela abaklami ukuthi bakhe ama-rack mortar racks amaningi. Ochwepheshe be-Pyrotechnician abakukhuthazi ukusetshenziswa kwamashubhu e-PVC kumashubhu odaka ngoba avame ukuphahlazeka, athumele izingcezu zepulasitiki ezibukelini ezingaba khona, futhi ngeke abonakale kuma-X ray. . -
I-PLA green card iba yisixazululo esimeme esidumile embonini yezezimali.
Ipulasitiki eningi iyadingeka ukwenza amakhadi asebhange njalo ngonyaka, futhi ngokukhula kokukhathazeka kwemvelo, uThales, umholi wezokuphepha zobuchwepheshe obuphezulu, uye wasungula isisombululo. Isibonelo, ikhadi elenziwe nge-85% ye-polylactic acid (PLA), etholakala kummbila; enye indlela entsha ukusebenzisa izicubu zokuhlanza ugu ngokusebenzisana neqembu lezemvelo iParley for the Oceans. Imfucumfucu yepulasitiki eqoqiwe - "i-Ocean Plastic®" njengento emisha yokukhiqiza amakhadi; kukhona futhi inketho yamakhadi e-PVC aphinde agaywa kabusha enziwe ngokuphelele kusuka kudoti epulasitiki kusuka embonini yokupakisha nokuphrinta ukuze kuncishiswe ukusetshenziswa kwepulasitiki entsha. . -
Ukuhlaziywa okufushane kwedatha ye-China yokunamathisela i-pvc resin yokungenisa nokuthekelisa kusuka ngoJanuwari kuya kuJuni.
Kusukela ngoJanuwari kuya kuJuni 2022, izwe lami langenisa amathani angama-37,600 e-paste resin, ukwehla ngama-23% uma kuqhathaniswa nesikhathi esifanayo ngonyaka owedlule, futhi lathumela ngaphandle ingqikithi yamathani angama-46,800 e-paste resin, okuwukunyuka kwama-53.16% uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule. Engxenyeni yokuqala yonyaka, ngaphandle kwamabhizinisi angawodwana avala ukuze alungiswe, umthwalo wokusebenza wefektri ye-paste resin yasekhaya yahlala isezingeni eliphezulu, ukuhlinzekwa kwezimpahla kwakwanele, futhi imakethe iqhubekile nokwehla. Abakhiqizi bafune ngenkuthalo imiyalo yokuthekelisa ukuze banciphise ukungqubuzana kwezimakethe zasekhaya, futhi ivolumu yokuthunyelwa kwempahla eqoqwayo yanda kakhulu . -
Ungabona kanjani ukuthi ipulasitiki iyi-polypropylene?
Enye yezindlela ezilula zokwenza ukuhlola ilangabi ukusika isampula epulasitiki bese uyithungela ekhabetheni lomusi. Umbala welangabi, iphunga nezici zokushiswa kunganikeza inkomba yohlobo lwepulasitiki: 1. I-Polyethylene (PE) - Amaconsi, anuka njenge-candlewax; 2.Polypropylene (PP) - Amaconsi, anuka kakhulu amafutha enjini angcolile kanye ne-undertones ye-candlewax 3. Polyethylene (PE) - I-Drips, iphunga njenge-candlewax; 4. I-Polyamide noma “Inayiloni” (PA) – Ilangabi elithambile, iphunga lama-marigolds; 5. I-Acrylonitrilebutadienestyrene (ABS) – Alibonakali obala, ilangabi le-sooty, iphunga lama-marigolds; 6. Igwebu le-polyethylene (PE) – Ukuconsa, iphunga le-candlewax -
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 isicelo emaphaketheni, ezimotweni, ezinhle zabathengi, ezokwelapha, amafilimu asakazwayo, njll. I-PP isiphenduke into yokuzikhethela, ikakhulukazi uma ufuna i-polymer enamandla amakhulu (isb., vs Polyamide) ezinhlelweni zobunjiniyela noma umane ubheka inzuzo yezindleko ekubumbeni amabhodlela okuvuthela (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, ngokuthuthukiswa kwesimo sobhubhane kanye nochungechunge lwezinyathelo ezethulwe nguhulumeni waseShayina ukuze kukhuthazwe ukusimama komnotho, izinga lokusebenza lamabhizinisi okukhiqiza we-PVC asekhaya liye laba phezulu kakhulu, imakethe yokuthekelisa ye-PVC iye yafudumala, futhi isidingo samadiski angaphandle sikhulile. Inombolo ibonisa ukuthambekela okuthile kokukhula, futhi ukusebenza okuphelele kwemakethe kuye kwaba ngcono uma kuqhathaniswa nesikhathi esidlule.
