Tam sim no, cov kev siv tseem ceeb ntawm cov khoom siv hauv qab nopolyethylenehauv 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.
Cov thawj uas yuav ris lub nra hnyav, feem ntau ntawm kev siv cov khoom siv rov qab yog zaj duab xis. Rau kev lag luam khoom siv zaj duab xis, cov khoom siv tseem ceeb yog zaj duab xis ua liaj ua teb, zaj duab xis kev lag luam thiab zaj duab xis ntim khoom. Txawm li cas los xij, nyob rau xyoo tas los no, cov yam xws li kev txwv rau cov hnab yas thiab kev qaug zog ntawm kev thov vim muaj tus kab mob sib kis tau ua rau lawv ntxhov siab ntau zaus, thiab lawv tab tom ntsib qhov xwm txheej txaj muag. Kev thov rau cov khoom siv yas pov tseg ib txwm yuav maj mam hloov los ntawm kev nrov ntawm cov yas uas lwj tau. Ntau lub tuam txhab tsim zaj duab xis kuj tab tom ntsib kev tsim kho tshiab hauv kev lag luam, thiab maj mam txhim kho mus rau cov yeeb yaj kiab kev lag luam rov ua dua tshiab nrog cov khoom zoo thiab kev ua tau zoo dua. Txawm li cas los xij, vim muaj kev lwj ntawm cov yeeb yaj kiab yas uas lwj tau, muaj cov kev xav tau zoo rau kev ntim khoom sab nraud, lossis kev thov rau cov yeeb yaj kiab ntim khoom sab nraud uas yuav tsum tau khaws cia ntev dhau lub sijhawm lwj, thiab cov yeeb yaj kiab kev lag luam thiab lwm yam teb tseem tsis tuaj yeem hloov pauv tau, yog li cov khoom siv zaj duab xis tseem yuav siv. Nws tau muaj nyob ua cov khoom tseem ceeb tom qab ntawm polyethylene ntev heev, tab sis tej zaum yuav muaj kev qeeb hauv kev loj hlob ntawm kev siv thiab kev poob qis hauv qhov feem pua.
Ntxiv mus, cov lag luam xws li kev txhaj tshuaj molding, cov kav dej, thiab cov qhov khoob uas muaj feem cuam tshuam nrog kev tsim khoom thiab lub neej yuav tseem yog cov khoom siv tseem ceeb hauv qab polyethylene hauv ob peb xyoos tom ntej no, thiab tseem yuav raug tswj hwm los ntawm cov khoom siv hauv paus, cov khoom siv niaj hnub, thiab cov cuab yeej thiab khoom siv hauv zej zog. Tib neeg txoj kev ua neej nyob txuas nrog cov khoom siv ruaj khov, thiab qhov kev thov rau cov khoom puas tsuaj raug txo qis. Qhov teeb meem tseem ceeb uas cov lag luam saum toj no ntsib tam sim no yog tias qhov kev loj hlob ntawm cov vaj tse tau nyob twj ywm hauv xyoo tas los no. Vim muaj cov yam ntxwv xws li kev tawm tswv yim tsis zoo rau cov neeg nyob hauv kev xav noj mov los ntawm kev sib kis rov qab, kev txhim kho ntawm kev lag luam khoom lag luam tab tom ntsib qee qhov kev tiv thaiv kev loj hlob. Yog li ntawd, qhov kev hloov pauv hauv lub sijhawm luv luv yog qhov txwv tsawg, tsawg dua cuam tshuam los ntawm cov khoom puas tsuaj, kev lag luam yeeb nkab yuav raug cuam tshuam los ntawm cov cai, thaum kev txhaj tshuaj molding thiab cov khoom khoob raug cuam tshuam ntau dua los ntawm cov neeg nyob hauv kev xav noj mov, thiab qhov kev loj hlob yuav qeeb rau ib lub sijhawm yav tom ntej.
Nrog rau kev txhim kho tas mus li ntawm kev tshawb fawb thiab thev naus laus zis, kev tsim kho tshiab ntawm cov khoom yas thiab kev ua kom tib neeg zoo li tib neeg, nrog rau kev tsim kho tshiab zoo ntawm cov khoom thiab cov kev cai tsim khoom raws li qhov xav tau kuj tseem niaj hnub txhim kho. Yog li ntawd, yav tom ntej, kev lag luam khoom yas yuav ua rau muaj kev thov rau qee cov khoom siv raw uas txhim kho kev ua tau zoo ntawm cov khoom yas, xws li metallocenes, dov yas, cov ntaub ntawv txheej thiab lwm yam khoom muaj nqis ntxiv lossis cov khoom muaj nqis tshwj xeeb hauv cov teb tshwj xeeb. Tsis tas li ntawd, vim muaj kev tsim khoom ntau ntawm cov tuam txhab tsim khoom polyethylene hauv xyoo tas los no, ua rau muaj kev hloov pauv khoom loj, thiab kev tsis sib haum xeeb ntawm Russia thiab Ukraine thaum lub xyoo ua rau muaj nqi roj siab los thawb cov txiaj ntsig ethylene hauv qab, thiab kev nce nqi thiab kev muab khoom ua rau muaj kev sib xws ntawm cov khoom. Nyob rau hauv qhov xwm txheej tam sim no, cov chaw tsim khoom polyethylene tab tom ua haujlwm ntau dua hauv kev tsim cov khoom muaj nqis ntxiv xws li metallocenes, rotational molding, thiab coatings, raws li kev txhim kho ntawm cov lag luam hauv qab. Yog li ntawd, qhov kev loj hlob ntawm cov khoom yuav nce mus rau qee qhov hauv yav tom ntej.
Tsis tas li ntawd xwb, thaum muaj tus kab mob sib kis mus ntxiv tas li, nrog rau kev tshawb fawb thiab kev tsim cov hom tshiab los ntawm cov chaw tsim khoom, cov polyethylene fibers, cov khoom siv kho mob thiab cov khoom tiv thaiv tshwj xeeb kuj maj mam ua raws li thiab tsim, thiab kev thov yav tom ntej kuj tseem yuav nce ntxiv tas li.
