Isingeniso mayelana Nomthamo we-PVC e-China nasemhlabeni jikelele
Ngokwezibalo zango-2020, umthamo wokukhiqiza we-PVC emhlabeni wonke wafinyelela kumathani ayizigidi ezingama-62 kanti inani eliphelele lafinyelela kumathani ayizigidi ezingama-54. Konke ukuncipha komkhiqizo kusho ukuthi umthamo wokukhiqiza awuhambanga ngo-100%. Ngenxa yezinhlekelele zemvelo, izinqubomgomo zendawo kanye nezinye izici, umkhiqizo kufanele ube ngaphansi komthamo wokukhiqiza. Ngenxa yezindleko eziphakeme zokukhiqiza ze-PVC eYurophu nase-Japan, amandla okukhiqiza e-PVC emhlabeni wonke agxile kakhulu eNyakatho-mpumalanga ye-Asia, lapho i-China inengxenye yomthamo wokukhiqiza we-PVC womhlaba wonke. Ngokusho kwedatha yomoya, ngo-2020, i-China, i-United States ne-Japan yizindawo ezibalulekile zokukhiqiza i-PVC emhlabeni, amandla okukhiqiza afinyelela ku-42%, 12% no-4% ngokulandelanayo. Ngo-2020, amabhizinisi amathathu aphezulu emhlabeni jikelele we-PVC ... -
I-Trend yesikhathi esizayo ye-PVC Resin
I-PVC iwuhlobo lwepulasitiki olusetshenziswa kabanzi ezintweni zokwakha. Ngakho-ke, ngeke ithathelwe indawo isikhathi eside esikhathini esizayo, futhi izoba nethuba elihle lokufaka isicelo ezindaweni ezingathuthukisiwe esikhathini esizayo. Njengoba sonke sazi, kunezindlela ezimbili zokukhiqiza i-PVC, enye iyindlela evamile yomhlaba wonke ye-ethylene, kanti enye iyindlela eyingqayizivele ye-calcium carbide e-China. Imithombo yendlela ye-ethylene ikakhulukazi i-petroleum, kanti imithombo yendlela ye-calcium carbide ikakhulukazi amalahle, i-limestone nosawoti. Lezi zinsiza zigxile kakhulu eShayina. Isikhathi eside, indlela yaseChina ye-PVC ye-calcium carbide ibilokhu isendaweni ehamba phambili ngokuphelele. Ikakhulukazi kusukela ngo-2008 kuya ku-2014, umthamo wokukhiqiza we-PVC waseChina wendlela ye-calcium carbide ubulokhu ukhula, kodwa futhi ulethe ... -
Iyini i-PVC Resin?
I-Polyvinyl chloride (PVC) iyi-polymer eyenziwe nge-vinyl chloride monomer (VCM) ku-peroxide, i-azo compound nezinye iziqalisi noma ngokuya ngomshini we-polymerization wamahhala ngaphansi kwesenzo sokukhanya nokushisa. I-vinyl chloride homopolymer kanye ne-vinyl chloride copolymer zihlangene 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 nezintambo, ifilimu yokupakisha, amabhodlela, izinto ezigwebu, izinto zokuvala, imicu nokunye. Ngokusho kobubanzi besicelo esihlukile, i-PVC ingahlukaniswa ibe: i-resin ye-PVC yenhloso evamile, izinga eliphezulu le-polymerization PVC resin kanye ... -
Iwindi lokuthekelisa le-arbitrage le-PVC liyaqhubeka nokuvuleka
Ngokuphathelene nesici sokuhlinzeka, i-calcium carbide, ngesonto eledlule, intengo yemakethe evamile ye-calcium carbide yehliswe ngo-50-100 yuan / ton. Umthwalo ophelele wokusebenza wamabhizinisi e-calcium carbide wawuzinzile, futhi ukuhlinzekwa kwezimpahla kwakwanele. Ethintwe yilolu bhubhane, ukuthuthwa kwe-calcium carbide akusheleli, intengo yefekthri yezinkampani yehliswa ukuze kuvunyelwe ukuthuthwa kwenzuzo, ukucindezela kwezindleko ze-calcium carbide kukhulu, futhi ukwehla kwesikhathi esifushane kulindeleke ukuba kube nomkhawulo. Umthwalo wokuqalisa wamabhizinisi akhuphukayo we-PVC unyukile. Ukunakekelwa kwamabhizinisi amaningi kugxile phakathi nasekupheleni kuka-April, futhi umthwalo wokuqalwa uzohlala uphezulu kakhulu esikhathini esifushane. Ethintwe yilolu bhubhane, imali yokusebenza... -
Abasebenzi baseChemdo basebenzisana ukulwa nalolu bhubhane
NgoMashi 2022, iShanghai yasebenzisa ukuvalwa nokulawulwa kwedolobha futhi yalungiselela ukwenza "uhlelo lokusula". Manje sekumaphakathi no-April, singabuka kuphela indawo enhle ngaphandle kwefasitela ekhaya. Akekho owayelindele ukuthi ukuthambekela kwalolu bhubhane e-Shanghai kuzokwanda kakhulu, kodwa lokhu akusoze kwawumisa isasasa leChemdo yonke entwasahlobo ngaphansi kwalolu bhubhane. Bonke abasebenzi bakwaChemdo basebenzisa "ukusebenzela ekhaya". Yonke iminyango isebenza ngokubambisana futhi ibambisane ngokugcwele. Ukuxhumana komsebenzi kanye nokunikezela kwenziwa nge-inthanethi ngendlela yevidiyo. Nakuba ubuso bethu kuvidiyo buhlala bungenazo izimonyo, isimo sengqondo esibucayi ngomsebenzi sichichima esikrinini. Omi bafo... -
Imakethe yomhlaba wonke yamapulasitiki angaboli kanye nesimo sokusetshenziswa
I-Chinese Mainland Ngo-2020, ukukhiqizwa kwezinto ezibolayo (okuhlanganisa i-PLA, i-PBAT, i-PPC, i-PHA, amapulasitiki asekelwe isitashi, njll.) e-China kwakungamathani angaba ngu-400000, futhi ukusetshenziswa kwakungamathani angaba ngu-412000. Phakathi kwazo, ukuphuma kwe-PLA kungamathani ayi-12100, umthamo wokungenisa ungamathani angama-25700, umthamo wokuthekelisa ungamathani angama-2900, kanti ukusetshenziswa okubonakala kungamathani angama-34900.

Uchungechunge lwemboni yaseChina ye-polylactic acid (PLA) ngo-2021
1. Uhlolojikelele lochungechunge lwezimboni: Igama eligcwele le-polylactic acid i-poly lactic acid noma i-poly lactic acid. Kuyinto ephezulu ye-polyester yamangqamuzana etholwe ngokwenza i-polymerization nge-lactic acid noma i-lactic acid dimer lactide njenge-monomer. Iyingxenye ye-synthetic high molecular material futhi inezici zesisekelo sebhayoloji kanye nokuwohloka. Njengamanje, i-polylactic acid iyipulasitiki ebolayo enezimboni ezivuthwe kakhulu, umkhiqizo omkhulu futhi osetshenziswa kakhulu emhlabeni. Imboni ephezulu ye-polylactic acid yizo zonke izinhlobo zezinto zokusetshenziswa eziyisisekelo, ezifana nommbila, umoba, isithombo sebhitrudi, njll. -
I-biodegradable polymer PBAT ishaya kakhulu
I-polymer ephelele—elinganisa izakhiwo ezingokomzimba nokusebenza kwemvelo—ayikho, kodwa i-polybutylene adipate co-terephthalate (PBAT) isondela kakhulu kuneziningi. Abakhiqizi bama-polymer okwenziwa sekungamashumi eminyaka behluleka ukumisa imikhiqizo yabo ukuthi igcine isendaweni yokulahla imfucumfucu kanye nolwandle, futhi manje bangaphansi kwengcindezi yokuba bazibophezele. Abaningi benza imizamo ephindwe kabili yokuthuthukisa ukugaywa kabusha ukuze kugwenywe abagxeki. Amanye amafemu azama ukubhekana nenkinga kadoti ngokutshala imali kumapulasitiki asuselwa ku-biodegradable biobased njenge-polylactic acid (PLA) ne-polyhydroxyalkanoate (PHA), ngethemba lokuthi ukucekelwa phansi kwemvelo kuzonciphisa okungenani enye imfucuza. Kodwa kokubili ukugaywa kabusha kanye nama-biopolymers abhekana nezithiyo. Nakuba iminyaka... -
