Tam sim no, qhov ntim ntawm polyethylene hauv kuv lub teb chaws yog qhov loj, thiab kev faib tawm ntawm cov kab hauv qab yog qhov nyuaj thiab feem ntau muag ncaj qha rau cov khoom lag luam yas.Nws belongs rau ib feem ntawm cov khoom kawg nyob rau hauv downstream kev lag luam saw ntawm ethylene.Ua ke nrog kev cuam tshuam ntawm lub regional concentration ntawm domestic noj, lub regional mov thiab kev thov sib txawv tsis sib npaug.
Nrog rau kev nthuav dav ntawm cov peev txheej ntau lawm ntawm kuv lub teb chaws polyethylene upstream ntau lawm cov lag luam nyob rau hauv xyoo tas los no, cov khoom lag luam tau nce ntau.Nyob rau tib lub sijhawm, vim kev txhim kho txuas ntxiv ntawm cov neeg nyob hauv kev tsim khoom thiab kev ua neej nyob, qhov kev thov rau lawv tau nce tsis tu ncua nyob rau xyoo tas los no.Txawm li cas los xij, txij li ib nrab xyoo 2021, qhov xwm txheej thoob ntiaj teb tau ua txhaum thiab hloov pauv.Kev kis tus kab mob sib kis thiab kev ua tsov rog hauv zos tau ua rau muaj kev tsis sib haum xeeb hauv lub ntiaj teb lub zog-nyiaj txiag kev txiav txim.vau.Qhov kev tsis txaus ntseeg ntau ntxiv hauv macro-kev lag luam tau ua rau cov neeg nyob hauv kev noj qab haus huv mus rau theem ceev faj.Raws li qhov xwm txheej tam sim no, cov kev pheej hmoo thiab cov teeb meem ntsib los ntawm kev tsim cov khoom siv polyethylene kuj hnyav dua.
Cov pejxeem thiab kev loj hlob ntawm kev lag luam txiav txim qhov kev faib khoom ntawm PE.Los ntawm qhov kev xav ntawm cov cheeb tsam kev noj qab haus huv, East Tuam Tshoj, South Tuam Tshoj, thiab North Tuam Tshoj yog cov chaw noj khoom haus tseem ceeb rau kev siv dej hauv qab ntawm cov polyethylene hauv kuv lub teb chaws, thiab yuav nyob twj ywm rau peb sab saum toj ntawm kev noj rau lub sijhawm ntev tuaj.Txawm li cas los xij, nrog kev tso tawm tas li ntawm cov cuab yeej tsim khoom tshiab yav tom ntej, nws xav tias qhov sib txawv ntawm peb qhov kev siv loj yuav raug txo kom tsawg.Nws cia siab tias qhov no yuav cuam tshuam loj rau yav tom ntej cov khoom siv thiab kev xav tau qauv thiab cov khoom lag luam nkag mus rau hauv cov cheeb tsam loj.Nws kuj tseem tsim nyog hais tias txawm hais tias qhov feem pua ntawm cov kev xav tau qis hauv thaj av sab hnub poob tsawg dua li ntawm East Tuam Tshoj, South Tuam Tshoj, thiab North Tuam Tshoj, uas tau tsav los ntawm cov kev cai hauv tebchaws xws li "Ib Txoj Kev Siv, Ib Txoj Kev" thiab "Kev Txhim Kho Sab Hnub Poob", Kev noj cov dej hauv qab ntawm polyethylene nyob rau thaj tsam sab hnub poob yuav nce ntxiv rau yav tom ntej.Muaj qhov kev cia siab nce ntxiv, tshwj xeeb tshaj yog rau cov khoom lag luam xav tau coj los ntawm cov kav dej, thiab qhov kev thov rau kev txhaj tshuaj molding thiab rotational molding cov khoom coj los ntawm kev txhim kho txuas ntxiv ntawm lub neej zoo yog pom tseeb dua.
Tom qab ntawd, nyob rau hauv cov nqe lus ntawm downstream noj ntau yam nyob rau hauv lub neej yav tom ntej, hom kev loj hlob kev cia siab yuav lub ntsiab downstream xav tau ntau yam ntawm polyethylene muaj?
Tam sim no, cov dej ntws tseem ceeb ntawm polyethylene hauv kuv lub teb chaws suav nrog zaj duab xis, txhaj tshuaj molding, yeeb nkab, hollow, hlau kos duab, cable, metallocene, txheej thiab lwm yam tseem ceeb.
Thawj qhov yuav tsum tau dais lub brunt, qhov loj tshaj plaws feem ntawm downstream noj yog zaj duab xis.Rau cov khoom lag luam zaj duab xis, lub ntsiab yog ua liaj ua teb zaj duab xis, muaj zaj duab xis thiab cov khoom ntim zaj duab xis.Txawm li cas los xij, nyob rau xyoo tas los no, yam xws li kev txwv cov hnab yas thiab rov ua kom tsis muaj zog ntawm kev thov vim muaj kev sib kis tau ua rau lawv nyuaj siab, thiab lawv tab tom ntsib teeb meem txaj muag.Qhov kev thov rau cov khoom siv yas pov tseg ib txwm siv yuav maj mam hloov nrog qhov nrov ntawm cov yas degradable.Ntau lub tuam txhab ua yeeb yaj kiab tseem tab tom ntsib kev lag luam thev naus laus zis tshiab, thiab maj mam txhim kho rau cov khoom siv rov ua dua tshiab nrog cov khoom zoo thiab kev ua haujlwm zoo.Txawm li cas los xij, vim qhov degradability ntawm cov yas yas degradable, muaj cov kev xav tau zoo rau kev ntim khoom sab nrauv, los yog qhov kev thov rau cov khoom ntim sab nrauv uas yuav tsum tau khaws cia rau lub sijhawm ntev dhau lub sijhawm degradation, thiab cov yeeb yaj kiab thiab lwm yam kev lag luam tseem tsis tau hloov, yog li cov khoom siv yeeb yaj kiab tseem yuav siv tau.Nws tau tshwm sim los ua cov khoom tseem ceeb ntawm cov khoom siv hauv qab ntawm polyethylene rau lub sijhawm ntev, tab sis tej zaum yuav muaj kev poob qis hauv kev noj haus thiab kev poob qis hauv qhov kev faib ua feem.
Tsis tas li ntawd, kev lag luam xws li kev txhaj tshuaj molding, cov kav dej, thiab cov hollows uas muaj feem cuam tshuam nrog kev tsim khoom thiab lub neej tseem yuav yog cov khoom siv tseem ceeb ntawm cov khoom siv hauv qab ntawm polyethylene nyob rau hauv ob peb xyoos tom ntej no, thiab tseem yuav muaj feem cuam tshuam los ntawm kev tsim kho vaj tse, khoom siv niaj hnub, thiab pej xeem. cov cuab yeej thiab khoom siv.Tib neeg txoj kev noj qab haus huv yog txuas nrog cov khoom siv ruaj khov, thiab qhov kev thov rau cov khoom degradation yog txo.Tam sim no, qhov teeb meem tseem ceeb ntawm kev lag luam saum toj no yog qhov kev loj hlob ntawm kev lag luam vaj tse tau stagnated nyob rau hauv xyoo tas los no.Vim muaj cov ntsiab lus xws li kev tawm tswv yim tsis zoo rau cov neeg nyob hauv kev noj qab haus huv kev xav tau coj los ntawm kev sib kis rov qab, kev txhim kho ntawm cov khoom lag luam tau ntsib qee qhov kev loj hlob tsis kam.Yog li ntawd, qhov kev hloov pauv ntawm lub sijhawm luv luv yog qhov txwv, thiab nws tsis tshua cuam tshuam los ntawm cov khoom degradation.Kev lag luam yeeb nkab feem ntau yuav cuam tshuam los ntawm cov cai, thaum txhaj tshuaj molding thiab cov khoom hollow cuam tshuam ntau dua los ntawm cov neeg nyob hauv kev xav, thiab kev loj hlob yuav qeeb yav tom ntej.muaj peev xwm.
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev tsim tus kheej thiab tib neeg kev tsim kho tshiab ntawm cov khoom yas, nrog rau cov khoom lag luam zoo thiab cov kev cai tsim khoom lag luam kuj tseem txhim kho tas li.Yog li ntawd, nyob rau hauv lub neej yav tom ntej, kev lag luam khoom yas yuav ua rau kom muaj kev thov rau qee cov ntaub ntawv raw uas txhim kho kev ua tau zoo ntawm cov khoom yas, xws li metallocenes, dov plastics, txheej cov ntaub ntawv thiab lwm yam khoom muaj nqis ntxiv lossis cov khoom lag luam nrog cov kev cai tshwj xeeb hauv kev tshwj xeeb. .Nyob rau hauv tas li ntawd, vim lub concentrated zus tau tej cov upstream polyethylene kev lag luam nyob rau hauv lub xyoo tsis ntev los no, ua rau cov khoom loj inversion, thiab kev tsis sib haum xeeb ntawm Russia thiab Ukraine nyob rau hauv lub xyoo ua rau cov nqi roj siab los thawb downstream profits ntawm ethylene, thiab surge nyob rau hauv tus nqi. thiab cov khoom tau ua rau cov khoom loj homogeneity.Raws li qhov xwm txheej tam sim no, polyethylene Manufacturers tau dhau los ua cov khoom lag luam muaj txiaj ntsig zoo ntxiv xws li metallocenes, rotational molding, thiab coatings, nyob rau hauv txoj kab nrog kev txhim kho ntawm kev lag luam hauv qab.Yog li ntawd, kev loj hlob ntawm cov khoom yuav nce mus rau ib qho twg yav tom ntej.
Tsis tas li ntawd, raws li kev kis kab mob txuas ntxiv mus ntxiv, nrog rau kev tshawb fawb thiab kev tsim cov npe tshiab los ntawm cov tuam txhab, polyethylene fibers, kev kho mob thiab kev tiv thaiv cov khoom tshwj xeeb kuj maj mam ua raws thiab tsim, thiab cov kev xav tau yav tom ntej kuj tseem yuav nce ntxiv mus.
