Ukuhlaziywa kwezindleko zokukhiqiza kwe-PVC
Ukuhlaziywa kwezindleko zokukhiqiza kwe-PVC,
I-calcium carbide indlela ye-PVC, ethylene indlela PVC izindleko, Imali yokuthengisa ye PVC, Abakhiqizi be-PVC, Izindleko ze-PVC zenqubo ye-vinyl,
Eminyakeni yamuva, intengo ye-PVC ishintshashintsha kakhulu, futhi inzuzo yamabhizinisi anezinqubo ezahlukene nayo ihluke kakhulu.Amabhizinisi anempahla yokusetshenziswa esekelayo enza inzuzo, kuyilapho amabhizinisi adinga ukuqoqa izinto zokusetshenziswa ebhekene nokulahlekelwa.
Njengoba inqubo yokukhiqiza ye-PVC idla amathani angu-1.4 e-calcium carbide ngethani, ushintshoImali yokuthengisa ye PVCIndlela ye-calcium carbide ithinteka kakhulu yi-calcium carbide.Kusukela ngo-Okthoba 2020, intengo ekhuphukayo ye-calcium carbide iholele ekwenyukeni kwe-Imali yokuthengisa ye PVC.Ikakhulukazi ngemva kuka-2021, ngaphansi kwesizinda sokuhlolwa kokusetshenziswa kukagesi, i-calcium carbide, njengemboni yokusetshenziswa kwamandla aphezulu, ivinjelwe kakhulu.Izindleko zamabhizinisi e-PVC bezilokhu zikhuphuka ngokunyuka.Ngo-Okthoba 2021, izindleko zamanye amabhizinisi e-East China zingaphezu kuka-15000 yuan/ton.Ekupheleni kuka-2022, inani le-calcium carbide seligcinwe ku-3900-4550 yuan/ton, ngentengo ephezulu evela maphakathi no-March kanye nenani eliphansi ekupheleni kukaFebruwari no-April.Ngakho-ke, izindleko zamabhizinisi e-PVC nazo ziyavumelana.
Izindleko ze-PVC zenqubo ye-vinylizinguquko zithintwa intengo ye-ethylene ne-vinyl chloride.Izindleko zamabhizinisi e-PVC asebenzisa indlela ye-ethylene zikhuphuka kancane kancane kusukela ekupheleni kuka-April 2020, kusukela ekuguqulweni kwe-VCM, isikhundla esiphezulu sivela ekupheleni kuka-Okthoba 2021, ngaphezu kwe-14,600 yuan/ton.NgoJanuwari 2022, ukuhlinzekwa kwe-vinyl chloride kwanda, futhi izindleko zamabhizinisi okukhiqiza i-PVC ohlelweni lwe-ethylene zehla;NgoFebhuwari isidingo se-vinyl chloride ezansi nomfula saba ngcono, intengo yakhuphuka;NgoMashi, ukuhlinzekwa kwe-VCM e-Asia kwakuqinile, futhi izindleko eziphezulu kakhulu zaziyi-9750 yuan/ton ekupheleni kuka-March.
Ngekota yokuqala ka-2022, izinga lenzuzo le-calcium carbide PVC lalilungile, lizuza kakhulu enanini eliphansi le-calcium carbide eluhlaza.NgoJanuwari, inzuzo enkulu ye-PVC ekhiqizwe izimayini zakwamanye amazwe e-Shandong yayingu-33.6 yuan/ton, ukwanda ngo-1182.6 yuan/ton, kanye nokwenyuka kwama-yuan/ton angu-6.6 unyaka nonyaka;Ekupheleni kukaFebhuwari, inzuzo ye-PVC eyenziwe ngokukhiqizwa ngaphandle kwama-electrolyte inyuke ngo-165.5 yuan/ton yaya ku-199.1 yuan/ton.Ekupheleni kuka-March, inzuzo ye-PVC ekhiqizwa ukukhiqizwa kwangaphandle kwetshe le-electrolytic yayingu-774 yuan/ton.
Ngokusho kwe-accounting evela ku-VCM, engxenyeni yokuqala ka-2022, izinga lenzuzo le-PVC elenziwe ngendlela ye-ethylene liphansi kunalelo lamabhizinisi e-calcium carbide.NgoJanuwari, izindleko zeAbakhiqizi be-PVCyehla, intengo yemakethe yenyuka kancane, futhi inzuzo yamabhizinisi yanda.Ngo-February, ehlaselwe intengo ephezulu eluhlaza vinyl chloride, ethylene indlela izindleko ukwanda, ngesikhathi esifanayo phakathi futhi ngasekupheleni February waqala buthaka ukuthambekela emakethe, ethylene indlela intengo ziba ngcono, vinyl indlela ukukhiqizwa kwangaphandle ukulahlekelwa okwengeziwe.NgoMashi, njengoba intengo ye-PVC ikhuphuka futhi intengo ye-VCM yehla, inzuzo yamabhizinisi e-PVC asebenzisa indlela ye-ethylene (PVC) yaba ngcono.Kodwa amabhizinisi e-vinyl PVC afuywayo angamadivayisi ahlanganisiwe, futhi isikhala senzuzo sikhulu kakhulu kunamabhizinisi e-PVC.
I-PVC isifinyezo se-polyvinyl chloride.I-resin yinto evame ukusetshenziswa ekukhiqizeni amapulasitiki namarabha.I-PVC resin iyimpushana emhlophe evame ukusetshenziselwa ukukhiqiza i-thermoplastics.Yimpahla yokwenziwa esetshenziswa kabanzi emhlabeni namuhla.I-Polyvinyl chloride resin inezici ezivelele njengokuchichima kwezinto zokusetshenziswa, ubuchwepheshe bokukhiqiza obuvuthiwe, intengo ephansi, kanye nenhlobonhlobo yokusetshenziswa.Kulula ukucubungula futhi ingacutshungulwa ngokubumba, i-laminating, ukubunjwa komjovo, i-extrusion, i-calendering, i-blow molding nezinye izindlela.Ngezakhiwo ezinhle zomzimba namakhemikhali, isetshenziswa kabanzi embonini, kwezokwakha, ezolimo, empilweni yansuku zonke, ekupakishayo, ugesi, izinsiza zomphakathi, nakweminye imikhakha.Ama-resin e-PVC ngokuvamile anokumelana namakhemikhali aphezulu.Inamandla kakhulu futhi imelana namanzi nokuhuzuka.I-Polyvinyl chloride resin (PVC) ingacutshungulwa ibe yimikhiqizo ehlukahlukene yepulasitiki.I-PVC iyipulasitiki engasindi, engabizi, futhi enobungani bemvelo.I-Pvc Resin ingasetshenziswa kumapayipi, amafreyimu amafasitela, amapayipi, izikhumba, izintambo zocingo, izicathulo kanye neminye imikhiqizo ethambile evamile, amaphrofayili, okokufakwayo, amaphaneli, umjovo, ukubumba, izimbadada, ishubhu eliqinile nezinto zokuhlobisa, amabhodlela, amashidi, ikhalenda, umjovo oqinile kanye nokubunjwa, njll nezinye izingxenye.
Izici
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanye nesikhumba sokwenziwa, ngokwengeza ama-plasticizers.
