Kev ua lag luam PVC sawv zoo li zaj sawv hauv lub Kaum Ib Hlis, thiab kev ua lag luam hloov tau zoo dua. Raws li cov ntaub ntawv raug saib xyuas los ntawm cov koom haum kev lag luam (nruab nrab ex Hoobkas nqe ntawm SG5 los ntawm calcium carbide txuj ci), lub Kaum Ib Hlis 1, tus nqi ntawm PVC nyob rau hauv Suav yog 6650 yuan / tuj, thaum Lub Kaum Ib Hlis 28, tus nqi ntawm PVC hauv Suav yog 6977.5 yuan / ton, nce 4.92% hauv lub hli, nce 8.80% xyoo rau xyoo. Thaum Lub Kaum Ib Hlis 28, PVC cov khoom lag luam txheeb tau 87.97, nce 0.47 ntsiab lus los ntawm nag hmo, nqis 12.03% los ntawm lub voj voog qhov siab tshaj ntawm 100.00 (2011-09-05), thiab nce 50.97% los ntawm qis tshaj ntawm 58.27 ntawm lub Kaum Ob Hlis 20, 2015 . (Ceebtoom: lub voj voog hais txog 2011-09-01 txog tam sim no)
II. Kev tshawb fawb txog kev ua lag luam
Cov khoom lag luam: Cov khoom lag luam tam sim no PVC txuas ntxiv mus rub tawm, zoo li muaj zog, txhua txoj kev liab, txhawb PVC chaw ua lag luam Tam sim no, PVC ua lag luam 5 chaw yog tsawg, thiab tus nqi ntawm ntau cov tuam ntxhab tau nce ntxiv. Txij li thaum Lub Kaum Hlis, qhov kev poob qis thiab kev saib xyuas ntawm PVC cov khoom lag luam tau dhau ntawm theem ntawm tib lub sijhawm ntawm xyoo tas los, nrog rau qhov cuam tshuam ntawm qhov tshwm sim ntawm tus nqi qis muag los ntawm cov tuam txhab tsim khoom thaum ntxov, uas tau ua rau lub zog cia ntws mus kom nquag. nqa cov khoom lag luam thiab ua kom nrawm raug txo cov khoom txua, kom cov khoom lag luam tam sim no tsawg heev. Nyob rau theem no, qee cov tuam ntxhab feem ntau tshuav nqi xaj thiab tsis lees txais cov xaj tshiab rau lub sijhawm, uas yog, qhov xwm txheej ntawm "koj muaj nyiaj, Kuv tsis muaj yam khoom" tshwm sim ntau zaus. Ntawm lawv, muaj qee tus tub lag luam uas tau siv lub sijhawm zoo los xav kwv yees, tab sis cov tuam txhab hauv qab dej tau nkees, kev yuav khoom txaus siab tsis siab, muaj ntau yam kev tsis sib haum xeeb, thiab qhov tseeb xa thiab peev xwm tiaj tus. Tam sim no North tau nkag mus rau lub caij cua sov, thaum kev lag luam nyob rau hauv lub caij so, cov vaj tsev, cov cuab yeej thiab lwm cov neeg siv pib txo qis, qhov kev thov rau PVC tsawg tsawg, thiab tom qab ntawd PVC txij nkawm lag luam maj mam txo, cov mov nce, thiab tus nqi PVC ua lag luam tus nqi yuav poob. Raws li cov ntaub ntawv soj ntsuam ntawm lub koom haum kev lag luam, txij li Lub Kaum Ib Hlis 28, qhov kev sib txuas loj ntawm cov khoom lag luam PVC yog 6650-7000 yuan / tuj. Tam sim no, cov nqi hluav taws xob tseem ceeb ntawm pvc5 carbide hauv Changzhou yog 7020-7100 yuan / tuj, tias ntawm pvc5 carbide hauv Hangzhou yog 7050-7100 yuan / tuj, thiab tias ntawm PVC cov carbide hauv Guangzhou yog 7240-7320 yuan / tuj. Cov nqi tau nce rau ntau qib.
Cov khoom lag luam: lub ntsiab xyoo 2001 daim ntawv cog lus ntawm PVC futures sawv hauv kev poob siab. Txog Lub Kaum Ib Hlis 28, nws tau kaw txog 2.09% thiab kaw tau 6870 lossis 55 thaum hmo ntuj. Tus nqi siab tshaj plaws nyob rau hauv kev sib kho yog 6905 yuan / ton, uas tau teeb tsa qhov tshiab tshiab hauv ze li ib nrab ntawm ib xyoos, teev ib ntus thawj hauv kev lag luam khoom lag luam yav tom ntej, thiab tseem tseem muaj kev tshawb nrhiav txuas ntxiv yav tom ntej.
Kev tsim tawm thiab xa tawm: Lub Kaum Hli 2019, Suav Teb tau tag nrho 546900 tons ntawm PVC 45377 tons. Txij Lub Ib Hlis Ntuj txog Lub Kaum Hli 2019, Suav Teb tau muab cov khoom lag luam PVC ntau txog 546900 tons. Lub Kaum Hlis 2019, 37900 tons ntawm PVC yuav raug xa tawm, thiab 452300 tons ntawm PVC yuav xa tawm txij Lub Ib Hlis mus txog Lub Kaum Hli.
Cov saw hlau muaj khoom lag luam: nyob rau yav tom ntej, cov nqi roj av tau tswj tau qhov nqaim ntawm cov kev sib zog, thiab qhov kev lag luam tag nrho tus nqi ntawm ethylene tau poob ua ntej, tom qab ntawd sawv thiab tom qab ntawd poob. Hais txog calcium carbide, kev ua haujlwm ntawm cov calcium carbide hauv Northwest Tuam Tshoj yog qhov qub, cov nqi sib xyaws yog qhov ruaj khov, thiab tus nqi ntawm cov khoom siv sab saud yog tsawg. Piv nrog rau xyoo tas los, tus nqi tau poob ntau heev, thiab tus nqi them yug yog qhov tsis txaus, uas muaj qhov tsis zoo rau tus nqi ntawm calcium carbide. Nyob rau hauv lub neej yav tom ntej, tus nqi ntawm calcium carbide yuav tsawg. PVC downstream khoom ntshuam txo qis, export nce kuj txhawb tus nqi
Kev lag luam: raws li kev saib xyuas tus nqi ntawm lub koom haum kev lag luam, nyob rau lub Kaum Ib Hlis 28, 2019, muaj peb yam khoom lag luam hauv daim ntawv teev npe nce thiab poob ntawm cov nqi khoom lag luam, suav nrog PVC (1.05%), LLDPE (0.45%) thiab styrene butadiene roj hmab (0.18%) Ib qho tag nrho ntawm 1 cov khoom lag luam poob rau ib hlis rau ib hlis, nrog cov roj hmab ntuj (- 0.17%) poob qis tus nqi nruab nrab ntawm hnub no yog 0.09%.
III. kev twv yav tom ntej
PVC cov kws tshuaj ntsuam ntseeg tias: tam sim no, cov ntawv pov thawj kev sib raug zoo tseem nyob rau theem qis, qhov xwm txheej ntawm qhov chaw tsis txaus yog qhov nyuaj rau kev hloov hauv lub sijhawm luv, thiab cov lag luam muaj zog txaus siab tuav tus nqi, thiab cia siab tias PVC cov nqi yuav txuas ntxiv kom sawv hauv lub sijhawm luv luv.
