HDPE muaj cov yam ntxwv ua tau zoo ntawm lub zog zoo, zoo toughness, zoo rigidity, thiab corrosion kuj, waterproof thiab noo noo-pov thawj, kub thiab txias kuj, yog li nws muaj ib qho tseem ceeb daim ntaub ntawv nyob rau hauv tshuab molding, txhaj tshuaj molding thiab yeeb nkab.Nrog rau kev tsim cov kev lag luam tiam sis xws li yas es tsis txhob hlau, yas es tsis txhob ntoo, HDPE raws li ib tug high-zoo polyethylene cov ntaub ntawv yuav leeb hloov cov tsoos ntaub ntawv nyob rau hauv lub neej yav tom ntej.Raws li cov khoom siv tseem ceeb ntawm kev ua liaj ua teb thiab ntim zaj duab xis, LDPE yog qhov qis dua LLDPE hauv cov khoom siv dag zog, rwb thaiv tsev kub thiab dej noo rwb thaiv tsev, thiab corrosion kuj.Yog li, kev lag luam xav tau ntawm LLDPE tau loj hlob sai nyob rau xyoo tas los no, maj mam nqos qee qhov kev lag luam ntawm LDPE.
1. Polyethylene (PE) kev lag luam saw
Polyethylene yog ib qho ntawm tsib qhov tseem ceeb hluavtaws cob, tab sis kuj yog lub peev xwm loj tshaj plaws ntawm cov khoom siv hluavtaws hauv tsev, imports ntau yam.Vim hais tias polyethylene yog upstream ntawm ethylene, ntau lawm yog raws li txoj kev naphtha, thiab cov profitability zoo sib xws.
Qhov loj tshaj plaws downstream daim ntawv thov ntawm polyethylene yog zaj duab xis, uas suav txog li 54% ntawm tag nrho cov kev thov rau polyethylene nyob rau hauv 2020. Tsis tas li ntawd, cov khoom siv tubular suav txog 12%, cov thawv hollow accounted rau 12%, txhaj tshuaj molding accounting rau 11%, thiab hlau. kev kos duab suav txog 4%.
2. Tam sim no qhov teeb meem ntawm polyethylene (PE) kev lag luam
Nyob rau hauv xyoo tas los no, lub teb chaws lub peev xwm ntawm polyethylene tau nce xyoo los ntawm xyoo.Los ntawm 2021, lub teb chaws lub peev xwm ntawm polyethylene yog kwv yees li 25,746,300 tons, nce 11.8% xyoo rau xyoo.
Hais txog kev tsim khoom, txij li xyoo 2018, Tuam Tshoj cov khoom siv polyethylene tau nce tsis tu ncua.Xyoo 2018, Tuam Tshoj cov khoom siv polyethylene yog kwv yees li 16.26 lab tons, thiab mus txog 22.72 lab tons hauv 2021, nrog rau qhov nruab nrab txhua xyoo kev loj hlob ntawm 11.8% nyob rau lub sijhawm.
Los ntawm 2015 mus rau 2020, pom meej noj polyethylene nyob rau hauv Tuam Tshoj maj mam nce, thiab nyob rau hauv 2021, pom meej noj ntawm polyethylene nyob rau hauv Tuam Tshoj poob mus rau 37.365,000 tons, ib tug txo ntawm 3.2% xyoo-rau-xyoo.Feem ntau yog vim muaj kev cuam tshuam ntawm kev sib kis thiab kev tswj xyuas ob lub zog siv, qee lub chaw tsim khoom hauv qab tau raug tshem tawm lossis txo qis ntau lawm.Nrog rau kev txhim kho ntawm tus kheej txaus, qhov kev cia siab ntawm PE yuav maj mam txo.Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntawm kev sib kis thiab kev loj hlob tsis tu ncua ntawm kev lag luam hauv tsev, qhov kev thov rau PE yuav nce ntxiv.
Raws li kev lis kev cai txheeb cais, txij lub Ib Hlis mus txog Lub Ob Hlis 2022, tag nrho cov khoom xa tuaj ntawm polyethylene yog kwv yees li 2,217,900 tons, 13.46% tsawg dua li tib lub sijhawm xyoo tas los.Peb lub teb chaws polyethylene imports ntau tshaj plaws los ntawm Saudi Arabia, tag nrho cov ntshuam yog 475,900 tons, accounting rau 21.46%;Qhov thib ob yog Iran, nrog rau tag nrho cov ntshuam ntawm 328,300 tons, suav txog 14.80%;Qhov thib peb yog United Arab Emirates, nrog rau tag nrho cov ntshuam ntawm 299,600 tons, suav txog 13.51%.
Hais txog kev xa tawm, txij lub Ib Hlis mus txog Lub Ob Hlis 2022, Tuam Tshoj cov polyethylene ntshuam ntim tau pom tias poob qis, thaum nyob rau hauv qhov sib txawv, kev xa tawm tau nce siab.Txog 53,100 tons ntawm polyethylene tau xa tawm thaum Lub Ib Hlis-Lub Ob Hlis 2022, nce 29.76% ntawm tib lub sijhawm xyoo tas los.Tshwj xeeb, LDPE xa tawm txog 22,100 tons, HDPE xa tawm txog 25,400 tons, thiab LLDPE xa tawm txog 50,600 tons.
3. Cov teeb meem kev lag luam ntawm polyethylene (PE) kev lag luam
Tam sim no, kev txhim kho ntawm polyethylene thev naus laus zis hauv Suav teb muaj cov teeb meem hauv qab no:
(1) Tsis muaj cov khoom siv polyethylene siab heev.Hauv Suav teb, tsuas yog Fushun Ethylene Chemical cog siv Sclairtech txheej txheem thev naus laus zis los tsim cov khoom lag luam octene 1 copolymerization, thiab tsuas yog Shanghai Jinshan Petrochemical Company muaj Borealis Bostar North Star supercritical polymerization txheej txheem thev naus laus zis.Insite solvent txheej txheem thev naus laus zis ntawm Dow Chemical Co., LTD tsis tau qhia hauv Suav teb.
(2) Qhov tsis muaj α-olefin copolymerization ntawm polyethylene raw cov ntaub ntawv thiab tshuab, Tuam Tshoj tau mastered lub copolymerization ntawm 1-butene thiab 1-hexene los npaj polyethylene, nyob rau hauv 1-octene, decene, 4-methyl-1-pentene thiab lwm yam α-olefin industrial ntau lawm yog tseem dawb paug.
(3) Cov nqi tsim khoom siab ntawm EVA raw cov ntaub ntawv, ob peb cov khoom uas muaj cov ntsiab lus VA siab, thiab kev siv zog me ntsis hauv kev tsim cov yeeb yaj kiab ua haujlwm thiab kub yaj nplaum.
