izindleko zokukhiqizwa kwe-PVC resin,
Intengo ye-PVC, Izindleko ze-PVC resin,
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.

Isicelo
Ngaphansi kwethonya lezingxabano zezombangazwe ezingatheni, izindleko zamandla omhlaba ziphezulu, futhi amazwe asentshonalanga akhetha ukukhuphula izinga lenzalo ukuze kuncishiswe ingozi yokwehla kwamandla emali, okubangela ukushaqeka komnotho emhlabeni wonke, kuhlangene nomthelela walolu bhubhane, futhi isidingo sezimakethe zomhlaba siyancipha. nomoya uyakhula.
E-China, inani lezakhiwo, abakhiqizi bephrofayili yepayipi yengqalasizinda bathi ngo-2022 ukukhiqizwa kwephrofayili yepayipi, idatha yokuthengisa yehla unyaka nonyaka, idlula kusukela ngoJanuwari kuya kuMeyi kulo nyaka, ukutshalwa kwezimali kwezwe lokuthuthukiswa kwezakhiwo kwehla ngo-4.0% ngonyaka, indawo entsha yokwakha izindlu yehle ngo-30.6%.Izimali ezikhona zamabhizinisi okuthuthukiswa kwezindlu zehle ngo-25.8% unyaka nonyaka.Dala imboni ukuthi ifune ukukhathazeka isikhathi eside.Imakethe yesikhathi esizayo ye-PVC yezinsuku ezingu-10 ezilandelanayo iphansi ye-intraday, kusukela ngoJuni 22 inkontileka ye-liansu ye-V2209 ephansi njenge-7352 yuan/ton.
Ngokusho kwenkundla yocwaningo lwedatha ye-longzhong, izindleko ezimaphakathi zamanje zamabhizinisi okukhiqiza e-PVC e-China ngu-7,082 yuan/ton wendlela ye-calcium carbide kanye ne-7,178 yuan/ton yendlela ye-ethylene.Kusukela ekukhululweni kwabezindaba, izindleko zamabhizinisi ezingaba ngu-35% zingaphezu kuka-7,500 yuan/ton, kanti izindleko zamabhizinisi ezingaba ngu-25% zingaphezu kuka-7,700 yuan/ton.
