I-reactor ye-PVC ye-giant ye-petrochemical eMpumalanga Ephakathi yaqhuma!
UPetkim, inkampani enkulu yamakhemikhali kaphethiloli yaseTurkey, umemezele ukuthi kusihlwa sangomhlaka-19 kuNhlangulana 2022, ukuqhuma kwenzeke esitshalweni sase-Aliaga lapho sitholakala khona ngamakhilomitha angama-50 enyakatho ye-lzmir. Ngokusho kwenkampani, ingozi yenzeke endaweni yokusabela i-PVC efektri, akekho owalimala, futhi umlilo walawulwa ngokushesha, kodwa idivayisi ye-PVC yayingasebenzi okwesikhashana ngenxa yengozi. Ngokusho kwabahlaziyi bendawo, lesi sigameko singaba nomthelela omkhulu emakethe ye-PVC yaseYurophu. Kubikwa ukuthi ngenxa yokuthi intengo ye-PVC eShayina iphansi kakhulu kuneyaseTurkey, kanti ngakolunye uhlangothi, intengo ye-PVC eYurophu iphakeme kuneyaseTurkey, imikhiqizo eminingi ye-PVC ye-petkim ithunyelwa emakethe yaseYurophu. -
Inqubomgomo yokuvimbela ubhubhane yalungiswa futhi i-PVC yaphinde yavuselelwa
Ngomhlaka-28 kuNhlangulana, inqubomgomo yokuvimbela nokulawula ubhubhane yehle, ukungabi nathemba ngemakethe ngesonto eledlule kwathuthuka kakhulu, imakethe yezimpahla ngokuvamile yabuya, futhi amanani aqondile kuzo zonke izingxenye zezwe athuthuka. Ngokubuya kwentengo, inzuzo yentengo eyisisekelo yehla kancane kancane, futhi iningi lezentengiselwano liyizivumelwano ezisheshayo. Ezinye izimo zezentengiselwano bezingcono kunayizolo, kodwa kwakunzima ukuthengisa imithwalo ngamanani aphezulu, futhi ukusebenza kwezentengiselwano bekungashintshi. Ngokuphathelene nezisekelo, ukuthuthuka ohlangothini lwesidingo kubuthakathaka. Njengamanje, isizini ephezulu isidlulile futhi kunendawo enkulu yemvula, futhi ukugcwaliseka kwesidingo kuncane kunalokho obekulindelekile. Ikakhulukazi ngaphansi kokuqonda kohlangothi lokunikezwa, isitokwe sisalokhu siphindaphindeka... -
Isingeniso mayelana nomthamo we-PVC eShayina nasemhlabeni jikelele
Ngokwezibalo zango-2020, umthamo wokukhiqiza we-PVC womhlaba wonke ufinyelele kumathani ayizigidi ezingama-62 kanti umkhiqizo uphelele ufinyelele amathani ayizigidi ezingama-54. Konke ukwehla komkhiqizo kusho ukuthi umthamo wokukhiqiza awuzange usebenze ngo-100%. Ngenxa yezinhlekelele zemvelo, izinqubomgomo zendawo nezinye izici, umkhiqizo kumele ube ngaphansi komthamo wokukhiqiza. Ngenxa yezindleko zokukhiqiza eziphezulu ze-PVC eYurophu naseJapan, umthamo wokukhiqiza we-PVC womhlaba wonke ugxile kakhulu eNyakatho-mpumalanga ye-Asia, lapho iShayina inengxenye yamandla okukhiqiza we-PVC womhlaba wonke. Ngokusho kwedatha yomoya, ngo-2020, iShayina, i-United States neJapan ziyizindawo ezibalulekile zokukhiqiza i-PVC emhlabeni, lapho umthamo wokukhiqiza ungaba ngu-42%, 12% kanye no-4% ngokulandelana. Ngo-2020, amabhizinisi amathathu aphezulu ku-PVC yomhlaba wonke... -
Umkhuba Wesikhathi Esizayo We-PVC Resin
I-PVC uhlobo lwepulasitiki olusetshenziswa kabanzi ezintweni zokwakha. Ngakho-ke, ngeke ithathelwe indawo isikhathi eside esikhathini esizayo, futhi izoba namathuba amahle okusetshenziswa ezindaweni ezingakathuthuki esikhathini esizayo. Njengoba sonke sazi, kunezindlela ezimbili zokukhiqiza i-PVC, enye iyindlela ejwayelekile ye-ethylene yamazwe ngamazwe, kanti enye iyindlela ehlukile ye-calcium carbide eShayina. Imithombo yendlela ye-ethylene iwuphethiloli, kanti imithombo yendlela ye-calcium carbide iwumalahle, i-limestone nosawoti. Lezi zinsiza zigxile kakhulu eShayina. Isikhathi eside, indlela ye-PVC ye-calcium carbide yaseShayina ibilokhu isendaweni ehamba phambili ngokuphelele. Ikakhulukazi kusukela ngo-2008 kuya ku-2014, amandla okukhiqiza i-PVC yaseShayina yendlela ye-calcium carbide abelokhu ekhula, kodwa futhi alethe ... -
Iyini i-PVC Resin?
I-Polyvinyl chloride (PVC) iyi-polymer eyenziwe nge-vinyl chloride monomer (VCM) ku-peroxide, i-azo compound kanye nezinye izinto zokuqala noma ngokwendlela yokwenza i-free radical polymerization ngaphansi kwesenzo sokukhanya nokushisa. I-homopolymer ye-vinyl chloride kanye ne-vinyl chloride copolymer zibizwa ngokuthi i-vinyl chloride resin. I-PVC yake yaba yipulasitiki enkulu kunazo zonke emhlabeni, eyayisetshenziswa kabanzi. Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, amathayili aphansi, isikhumba sokwenziwa, amapayipi, izintambo kanye nezintambo, ifilimu yokupakisha, amabhodlela, izinto zokufaka igwebu, izinto zokuvala, imicu nokunye. Ngokusho kobubanzi obuhlukene bokusetshenziswa, i-PVC ingahlukaniswa ibe: i-PVC resin yenhloso ejwayelekile, izinga eliphezulu le-polymerization i-PVC resin kanye ... -
Ifasitela le-arbitrage lokuthumela ngaphandle le-PVC liyaqhubeka nokuvulwa
Ngokuphathelene nesici sokuhlinzeka, i-calcium carbide, ngesonto eledlule, intengo yemakethe eyinhloko ye-calcium carbide yehliswe ngama-yuan angu-50-100 / ithani. Umthwalo wokusebenza ophelele wamabhizinisi e-calcium carbide wawuzinzile, futhi ukunikezwa kwezimpahla kwakwanele. Njengoba kuthintekile ubhubhane, ukuthuthwa kwe-calcium carbide akuhambanga kahle, intengo yefektri yamabhizinisi yehlisiwe ukuze kuvunyelwe ukuthuthwa kwenzuzo, ingcindezi yezindleko ze-calcium carbide inkulu, futhi ukwehla kwesikhashana kulindeleke ukuthi kunqunyelwe. Umthwalo wokuqala wamabhizinisi aphezulu e-PVC ukhuphukile. Ukugcinwa kwamabhizinisi amaningi kugxile maphakathi nasekupheleni kuka-Ephreli, futhi umthwalo wokuqala uzohlala uphezulu ngesikhathi esifushane. Njengoba kuthintekile ubhubhane, umthwalo wokusebenza... -
Abasebenzi eChemdo basebenzisana ukulwa nobhubhane
NgoMashi 2022, iShanghai yaqalisa ukuvalwa nokulawulwa kwedolobha futhi yalungiselela ukufeza "uhlelo lokuhlanza". Manje sekuphakathi no-Ephreli, singabuka kuphela indawo enhle ngaphandle kwefasitela ekhaya. Akekho owayelindele ukuthi ukuthambekela kobhubhane eShanghai kuzoba kubi kakhulu, kodwa lokhu ngeke kumise intshiseko yeChemdo yonke entwasahlobo ngaphansi kobhubhane. Bonke abasebenzi baseChemdo basebenzisa "umsebenzi ekhaya". Yonke iminyango isebenza ndawonye futhi ibambisana ngokugcwele. Ukuxhumana nomsebenzi kanye nokudluliselwa kwenziwa ku-inthanethi ngesimo sevidiyo. Nakuba ubuso bethu kuvidiyo buhlala bungenazo izimonyo, isimo sengqondo esingathi sína ngomsebenzi sigcwele isikrini. Omi ompofu... -
Imakethe yepulasitiki ebolayo yomhlaba wonke kanye nesimo sesicelo
Izwekazi laseShayina Ngo-2020, ukukhiqizwa kwezinto ezibolayo (kufaka phakathi i-PLA, i-PBAT, i-PPC, i-PHA, amapulasitiki asekelwe kusitashi, njll.) eShayina kwakungamathani angaba ngu-400000, kanti ukusetshenziswa kwakungamathani angaba ngu-412000. Phakathi kwazo, umkhiqizo we-PLA ungamathani angaba ngu-12100, umthamo wokungenisa ungamathani angu-25700, umthamo wokuthumela ngaphandle ungamathani angu-2900, kanti ukusetshenziswa okusobala kungaba ngamathani angaba ngu-34900. Izikhwama zokuthenga nezikhwama zemikhiqizo yasepulazini, ukupakisha ukudla nezinto zokudla etafuleni, izikhwama zomquba, ukupakisha igwebu, ezolimo kanye nezingadi zamahlathi, ukugqoka iphepha kuyizindawo ezinkulu zabathengi zepulasitiki ezibolayo eShayina.

I-YNCC yaseNingizimu Korea ishaywe ukuqhuma kwe-cracker okubulalayo kwe-Yeosu
IShanghai, 11 kuNhlolanja (Argus) — I-cracker ye-naphtha engu-No.3 yomkhiqizi wamakhemikhali kaphethiloli i-YNCC eYeosu complex ithole ukuqhuma namuhla okwabulala abasebenzi abane. Isigameko sango-9.26 ekuseni (12:26 GMT) sabangela ukuthi abanye abasebenzi abane bangeniswe esibhedlela ngenxa yokulimala okukhulu noma okuncane, ngokusho kweziphathimandla zomnyango womlilo. I-YNCC ibilokhu yenza izivivinyo ku-heat exchanger e-cracker ngemuva kokulungiswa. I-cracker engu-No.3 ikhiqiza ama-t/yr angu-500,000 kanye nama-t/yr angu-270,000 e-propylene ngomthamo ophelele wokukhiqiza. I-YNCC iphinde isebenzise amanye ama-cracker amabili eYeosu, angu-900,000 t/yr No.1 kanye nama-t/yr angu-880,000. Imisebenzi yabo ayithintekile.
