PVC ntau lawm nqi tsom xam
PVC ntau lawm nqi tsom xam,
calcium carbide txoj kev PVC, ethylene txoj kev PVC nqi, PVC nqi, PVC manufacturers, Vinyl txheej txheem PVC nqi,
Nyob rau hauv xyoo tas los no, tus nqi ntawm PVC fluctuates zoo heev, thiab cov nyiaj tau los ntawm cov lag luam nrog cov txheej txheem sib txawv kuj txawv heev.Kev lag luam nrog kev txhawb nqa cov ntaub ntawv raw yog cov txiaj ntsig, thaum cov lag luam uas xav tau los sau cov ntaub ntawv raw tau ntsib kev poob.
Raws li cov txheej txheem ntau lawm ntawm PVC siv 1.4 tons ntawm calcium carbide ib tuj, qhov kev hloov ntawmPVC nqiTxoj kev calcium carbide feem ntau cuam tshuam los ntawm calcium carbide.Txij li thaum Lub Kaum Hli 2020, tus nqi nce ntawm calcium carbide tau ua rau muaj kev nce ntxivPVC nqi.Tshwj xeeb tshaj yog tom qab xyoo 2021, nyob rau hauv keeb kwm yav dhau los ntawm kev ntsuas kev siv hluav taws xob, calcium carbide, raws li kev lag luam siv hluav taws xob siab, tau txwv ntau heev.Tus nqi ntawm PVC cov lag luam tau nce nrog qhov nce.Thaum Lub Kaum Hli 2021, tus nqi ntawm qee lub lag luam hauv East Tuam Tshoj yog ntau tshaj 15000 yuan / ton.Thaum kawg ntawm 2022, tus nqi calcium carbide tau khaws cia ntawm 3900-4550 yuan / ton, nrog tus nqi siab tshwm sim nyob rau nruab nrab Lub Peb Hlis thiab tus nqi qis thaum lub Ob Hlis thiab Plaub Hlis.Yog li ntawd, tus nqi ntawm PVC cov lag luam kuj yog synchronous.
Vinyl txheej txheem PVC nqiKev hloov pauv tau cuam tshuam los ntawm tus nqi ntawm ethylene thiab vinyl chloride.Tus nqi ntawm PVC cov tuam txhab uas siv txoj kev ethylene maj mam nce los ntawm qhov kawg ntawm lub Plaub Hlis 2020, pib los ntawm kev hloov dua siab tshiab ntawm VCM, txoj haujlwm siab tshaj plaws tshwm sim thaum lub Kaum Hlis 2021, ntau dua 14,600 yuan / tuj.Thaum Lub Ib Hlis Ntuj xyoo 2022, cov khoom siv vinyl chloride tau nce ntxiv, thiab cov nqi ntawm PVC cov tuam txhab tsim khoom hauv cov txheej txheem ethylene poob;Thaum Lub Ob Hlis Ntuj vinyl chloride downstream xav tau txhim kho, tus nqi nce;Thaum Lub Peb Hlis, cov khoom ntawm VCM hauv Asia tau nruj, thiab tus nqi siab tshaj plaws yog 9750 yuan / ton thaum kawg ntawm lub Peb Hlis.
Hauv thawj peb lub hlis twg ntawm 2022, cov nyiaj tau los ntawm calcium carbide PVC yog qhov ncaj ncees, feem ntau tau txais txiaj ntsig los ntawm tus nqi qis ntawm calcium carbide nyoos.Nyob rau hauv Lub ib hlis ntuj, tag nrho cov nyiaj tau los ntawm PVC ua los ntawm txawv teb chaws mining nyob rau hauv Shandong yog 33.6 yuan / tuj, nce 1182.6 yuan / tuj, thiab nce 6.6 yuan / tuj xyoo-rau-xyoo;Thaum kawg ntawm Lub Ob Hlis, cov txiaj ntsig ntawm PVC ua los ntawm cov khoom siv hluav taws xob sab nraud tau nce 165.5 yuan / tuj rau 199.1 yuan / tuj.Thaum kawg ntawm lub Peb Hlis, cov txiaj ntsig ntawm PVC ua los ntawm cov khoom siv sab nraud ntawm cov pob zeb electrolytic yog 774 yuan / tuj.
Raws li kev suav nyiaj los ntawm VCM, nyob rau hauv thawj peb lub hlis twg ntawm 2022, cov nyiaj tau los ntawm PVC ua los ntawm ethylene txoj kev yog qis dua li ntawm calcium carbide txoj kev lag luam.Lub Ib Hlis, tus nqi ntawmPVC manufacturerstau nqis mus, tus nqi lag luam tau nce me ntsis, thiab cov txiaj ntsig ntawm kev lag luam nce.Nyob rau hauv Lub Ob Hlis, cuam tshuam los ntawm tus nqi siab ntawm raw vinyl chloride, ethylene txoj kev nqi nce, tib lub sij hawm nyob rau hauv nruab nrab thiab lig Lub ob hlis ntuj pib tsis muaj zog rau kev lag luam sib, ethylene txoj kev nqi loosening, vinyl txoj kev ntawm sab nrauv zus tau tej cov poob ntau.Thaum lub Peb Hlis, raws li tus nqi ntawm PVC sawv thiab tus nqi ntawm VCM poob, cov txiaj ntsig ntawm PVC cov tuam txhab siv ethylene txoj kev (PVC) tau txhim kho.Tab sis cov tuam txhab PVC hauv tsev feem ntau yog cov khoom siv sib xyaw ua ke, thiab qhov chaw tau txais txiaj ntsig ntau dua li cov tuam txhab PVC.
PVC yog lub ntsiab lus rau polyvinyl chloride.Resin yog ib yam khoom siv feem ntau siv hauv kev tsim cov yas thiab roj hmab.PVC resin yog cov hmoov dawb feem ntau siv los tsim cov thermoplastics.Nws yog cov khoom siv hluavtaws dav siv hauv ntiaj teb niaj hnub no.Polyvinyl chloride resin muaj cov yam ntxwv zoo xws li cov khoom siv ntau, kev tsim khoom siv technology, tus nqi qis, thiab ntau yam kev siv.Nws yog ib qho yooj yim rau txheej txheem thiab tuaj yeem ua tiav los ntawm molding, laminating, txhaj tshuaj molding, extrusion, calendering, tshuab moulding thiab lwm yam.Nrog rau lub cev zoo thiab cov khoom siv tshuaj lom neeg, nws yog dav siv hauv kev lag luam, kev tsim kho, kev ua liaj ua teb, lub neej txhua hnub, ntim khoom, hluav taws xob, kev siv hluav taws xob, thiab lwm yam.PVC resins feem ntau muaj tshuaj tiv thaiv siab.Nws muaj zog heev thiab tiv taus dej thiab puas.Polyvinyl chloride resin (PVC) tuaj yeem ua tiav rau hauv ntau yam khoom yas.PVC yog lub teeb yuag, pheej yig, thiab ib puag ncig tus phooj ywg plastics.Pvc Resin tuaj yeem siv rau hauv cov kav dej, qhov rais thav duab, hoses, tawv, hlau cables, khau thiab lwm yam khoom muag muag, profiles, fittings, panels, txhaj tshuaj, molding, khau khiab, tawv raj thiab cov ntaub ntawv zoo nkauj, lub raj mis, nplooj ntawv, daim ntawv qhia hnub, txhav txhaj thiab moldings, thiab lwm yam.
Nta
PVC yog ib qho ntawm cov khoom siv thermoplastic feem ntau siv.Nws tuaj yeem siv los ua cov khoom lag luam nrog lub siab tawv thiab lub zog, xws li cov kav dej thiab fittings, profiled qhov rooj, qhov rais thiab cov ntawv ntim.Nws tseem tuaj yeem ua cov khoom muag muag, xws li cov yeeb yaj kiab, cov ntawv txheeb, cov xaim hluav taws xob thiab cov cables, cov ntaub pua tsev thiab cov tawv hluavtaws, los ntawm kev ntxiv cov yas yas
