Tam sim no, lub ntsiab downstream siv ntawmpolyethylenenyob rau 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 ntawm kev siv downstream 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 yas 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 ntim ntim cov yeeb yaj kiab uas yuav tsum tau muab 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 xyuam nrog kev tsim khoom thiab lub neej yuav nyob twj ywm cov khoom siv tseem ceeb ntawm cov khoom siv hauv qab ntawm polyethylene nyob rau ob peb xyoos tom ntej no, thiab tseem yuav muaj kev cuam tshuam los ntawm kev tsim kho vaj tse, khoom siv niaj hnub, thiab cov cuab yeej siv pej xeem thiab khoom siv. Tib neeg txoj kev noj qab haus huv txuas nrog cov khoom siv ruaj khov, thiab qhov kev thov rau cov khoom lag luam degradation raug txo. Qhov teeb meem tseem ceeb ntawm kev lag luam saum toj no tam sim 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 nyob rau lub sijhawm luv luv yog qhov txwv, tsis tshua muaj kev cuam tshuam los ntawm cov khoom lag luam degradation, cov yeeb nkab kev lag luam feem ntau yuav cuam tshuam los ntawm cov cai, thaum txhaj tshuaj molding thiab cov khoom hollow yog cuam tshuam ntau dua los ntawm cov neeg siv kev xav, thiab qhov kev loj hlob yuav qeeb rau lub sijhawm yav tom ntej.
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 cov khoom yas yuav nce qhov 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 thaj chaw tshwj xeeb. Tsis tas li ntawd, vim muaj kev sib xyaw ua ke ntawm cov chaw tsim khoom ntawm cov khoom lag luam polyethylene hauv xyoo tas los no, ua rau muaj kev cuam tshuam loj ntawm cov khoom lag luam, thiab kev tsis sib haum xeeb ntawm Russia thiab Ukraine hauv lub xyoo ua rau cov nqi roj siab los thawb cov nyiaj tau los ntawm cov ethylene, thiab kev nce nqi ntawm cov khoom lag luam thiab cov khoom lag luam ua rau muaj kev sib haum xeeb loj. 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.
