Kuv, kev lag luam tshuaj xyuas
PVC (6402, 10.00, 0.16%) daim ntawv cog lus tseem ceeb nyob rau lub Kaum Ob Hlis 30 tau kaw ntawm 6263 yuan / ton, ib hlis nce 312 yuan / ton (5.24%).
Saib rov qab rau lub Kaum Ob Hlis Ntuj tag nrho, nyob rau hauv thawj ib nrab ntawm lub hli, cov ntawv cog lus tseem ceeb tau qhia txog kev nce siab ua tsaug rau kev txwv tsis pub muaj kev sib kis txoj cai thiab kev txo qis ntawm txoj cai vaj tse.Nyob rau hauv ib nrab ntawm lub hlis thib ob, nrog rau kev rov cuam tshuam ntawm kev sib kis thiab kev thov qeeb thaum kawg ntawm lub xyoo, cov khoom siv thiab cov kev xav tau ua tsis tiav los muab cov lus pom zoo, thiab kev ua lag luam maj mam nkag mus rau kev poob siab.Nyob ze rau thaum xaus ntawm lub xyoo, cov nyiaj so koobtsheej tshwm sim ntxiv, uas qhia ib tug tag nrho upward trend.
II, tsom xam
PVC txheej txheem ntau lawm muaj ob hom: calcium carbide txoj kev thiab ethylene txoj kev, ethylene txoj kev ntawm PVC zoo ntshiab thiab niaj hnub, tus nqi yog me ntsis siab dua calcium carbide PVC txoj kev.Kev xa tawm ntau yam ntawm PVC yav tom ntej hauv peb lub tebchaws yog SG5 qib 1 ua raws li tus qauv hauv tebchaws.Tsis muaj kev txwv meej txog seb cov khoom xa tuaj yog ua los ntawm cov txheej txheem calcium carbide lossis cov txheej txheem yas.
Raws li lub Kaum Ob Hlis 30, 2022, tus nqi muag khoom thiab kev sib kis ntawm PVC tau qhia hauv qab no:
Hnub ntawd, tus nqi nruab nrab ntawm cov yas PVC hauv Suav teb yog 6,313 yuan / tuj, nce 165 yuan / tuj piv nrog rau lub hli tas los.
Nyob rau tib hnub, tus nqi nruab nrab ntawm cov khoom siv hauv tsev calcium carbide PVC yog 6,138 yuan / tuj, piv nrog rau lub hli tas los, nce 198 yuan / tuj.
Tus nqi sib txawv ntawm ethylene txoj kev thiab calcium carbide txoj kev nyob rau hnub ntawd yog 175 yuan / ton, piv nrog rau lub hli tas los, nce 33 yuan / ton, tus nqi sib txawv tseem nyob rau hauv keeb kwm qis.
Raws li lub Kaum Ob Hlis 30, 2022, PVC yav tom ntej tus nqi kis tau yog -66 yuan / tuj, 3 yuan / ton qis dua hnub dhau los, uas yog nyob rau theem qis hauv keeb kwm.
III.Kev txheeb xyuas khoom siv
Tau ntev, Tuam Tshoj PVC kev lag luam tau ua tus qauv kev txhim kho nrog ob hom kev siv tshuab, calcium carbide txoj kev thiab ethylene txoj kev, tab sis vim yog cov yam ntxwv ntawm "nplua nuj thee, roj tsis zoo thiab roj tsawg" cov peev txheej hauv peb lub tebchaws, calcium carbide txoj kev PVC tau dhau los ua cov thev naus laus zis hauv peb lub teb chaws, tab sis nyob rau hauv kev lag luam thoob ntiaj teb, cov khoom tseem ceeb PVC yog tsim los ntawm txoj kev ethylene, thiab ethylene yog tsim los ntawm lub zog tawg xws li roj thiab roj.Yog li tus nqi ntawm PVC thiab cov nqi roj thoob ntiaj teb qhia tias muaj kev sib raug zoo heev.
Cov txheej txheem ntawm vinyl PVC yog raws li nram no: roj crude - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Calcium carbide txheej txheem yog dav siv nyob rau hauv Suav chlor-alkali ntau lawm tuam txhab uas muag los tsim PVC, thiab cov zis ntawm PVC los ntawm calcium carbide txheej txheem account rau txog 80% ntawm tag nrho cov zis nyob rau hauv Tuam Tshoj.
Cov txheej txheem tsim cov calcium carbide polyvinyl chloride yog: Coal - calcium carbide - acetylene - vinyl chloride (VCM) - polyvinyl chloride (PVC) hluav taws xob txo txoj kev yog txoj kev tseem ceeb ntawm kev tsim cov calcium carbide tam sim no, txoj kev no siv coke (2798). , 29.50, 1.07%) thiab txiv qaub li raw cov ntaub ntawv, raws li ib tug ruaj ratio ntawm tov rau hauv lub kaw calcium carbide rauv, Calcium carbide yog tsim los ntawm hluav taws xob cua sov rau 2000-2200 degrees.Raws li txoj kev no yuav tsum tau siv lub zog hluav taws xob ntau, cov nqi hluav taws xob suav nrog ntau feem ntawm tag nrho cov nqi rau cov chaw tsim khoom siv polyvinyl chloride siv calcium carbide.
Txhawm rau ua kom tiav, tus nqi yav tom ntej ntawm PVC yog cuam tshuam los ntawm thermal thee (0, -921.00, -100.00%) (tus nqi hluav taws xob), coke thiab calcium carbide nqi tib lub sijhawm, qhia kev sib raug zoo.
Los ntawm Lub Ib Hlis 03, 2023, Tuam Tshoj lub zog thee rau yav tom ntej tus nqi yog 921 yuan / tuj, piv nrog rau hnub dhau los, tsis muaj kev hloov pauv;Coke tus nqi yog 2,610 yuan / ton, piv nrog rau hnub dhau los, nqis 95 yuan / ton.
Raws li lub Kaum Ob Hlis 30, 2022, qhov nruab nrab nqi ntawm calcium carbide nyob rau hauv mainstream calcium carbide factories nyob rau Northwest Tuam Tshoj yog 3,910 yuan / ton, uas tsis muaj kev hloov pauv nrog rau hnub dhau los.Tus nqi ntawm calcium carbide hauv lub tebchaws yog 4,101 yuan / ton, piv nrog rau hnub dhau los, tsis muaj kev hloov pauv.
Thaum cov tuam txhab chlor-alkali tsim cov tshuaj chlorine ua kua, lawv kuj tau txais cov dej qab zib caustic, cov khoom lag luam.Nyob rau hauv xyoo tas los no, tus nqi ntawm caustic soda thiab kua chlorine tsim cov nyhuv seesaw, uas yog, thaum tus nqi ntawm caustic soda yog siab, tus nqi ntawm cov kua chlorine kuj tsawg, thiab vice versa, uas ua rau cov nyiaj tau los ntawm chlor-alkali. cov tuam txhab tuav pov hwm nyob rau theem tsim nyog.Cov kua chlorine yog qhov nyuaj rau khaws cia thiab thauj mus ntev, yog li cov tuam txhab tsim khoom siv PVC thiab siv cov kua chlorine ntau dhau.
Lub downstream ntawm caustic soda mas suav nrog alumina, ntawv ua, luam ntawv thiab dyeing thiab tshuaj industries.Kev ua kom sov ntawm cov dej hauv qab ntawm cov dej qab zib caustic yuav ua rau muaj kev nce ntxiv ntawm cov dej qab ntsev ntawm cov chlor-alkali cov lag luam, thiab cov khoom lag luam cuam tshuam cov kua chlorine yuav ua rau hauv PVC, yog li ua rau kev ua lag luam ntawm PVC, uas yuav nias lub lag luam tus nqi. PVC rau ib qho twg.Feem ntau, PVC cov nqi yuav nyob twj ywm siab thaum cov nqi dej qab zib qis qis.
Raws li lub Kaum Ob Hlis 30, 2022, tus nqi ntawm ionic membrane caustic soda yog 1,344 yuan / ton, piv nrog rau hnub dhau los, tsis muaj kev hloov pauv, thiab tus nqi tam sim no yog nyob rau ntawm qhov chaw siab keeb kwm.
Tam sim no, qhov kev thov tseem ceeb rau caustic soda hauv Suav teb los ntawm cov khoom siv alumina txuas, yog li tus nqi ntawm cov dej qab zib caustic thiab tus nqi ntawm alumina qhia txog kev sib raug zoo.
Hauv tsev electrolytic aluminium yog dav siv hauv vaj tse, tsheb thiab hluav taws xob kev lag luam.Kev rov qab los ntawm cov kev lag luam hauv qab no yuav ua rau kom qhov kev thov rau cov khoom siv txhuas, uas yuav raug xa mus rau cov dej ntws, thawb cov nqi dej qab zib thiab tsis ncaj qha cuam tshuam rau tus nqi sib txawv ntawm PVC yav tom ntej.
Raws li lub Kaum Ob Hlis 30, 2022, tus nqi ntawm cov alumina hauv tsev yog 2,965 yuan / ton, tsis muaj kev hloov pauv nrog rau hnub dhau los, thiab tus nqi tam sim no nyob ntawm qhov chaw nruab nrab ntawm keeb kwm.
