Tam sim no, kev siv polyethylene hauv kuv lub teb chaws yog loj heev, thiab kev faib tawm ntawm cov hom downstream yog qhov nyuaj thiab feem ntau muag ncaj qha rau cov tuam txhab tsim khoom yas. Nws yog ib feem ntawm cov khoom kawg hauv kev lag luam downstream ntawm ethylene. Ua ke nrog qhov cuam tshuam ntawm thaj tsam concentration ntawm kev siv hauv tsev, qhov sib txawv ntawm kev muab khoom thiab kev thov hauv cheeb tsam tsis sib npaug.
Nrog rau kev nthuav dav ntawm lub peev xwm tsim khoom ntawm kuv lub teb chaws cov tuam txhab polyethylene upstream hauv xyoo tas los no, sab kev muab khoom tau nce ntxiv ntau heev. Tib lub sijhawm, vim yog kev txhim kho tas li ntawm cov neeg nyob hauv kev tsim khoom thiab cov qauv kev nyob, qhov kev thov rau lawv tau nce ntxiv tas li hauv xyoo tas los no. Txawm li cas los xij, txij li ib nrab xyoo 2021, qhov xwm txheej thoob ntiaj teb tau muaj kev phom sij thiab hloov pauv tau. Kev sib kis ntawm tus kab mob thiab kev ua tsov rog hauv zos tau ua rau muaj kev tsis sib npaug hauv kev txiav txim thoob ntiaj teb lub zog-nyiaj txiag. Kev puas tsuaj. Qhov tsis paub tseeb ntxiv hauv kev lag luam loj tau ua rau cov neeg nyob hauv kev xav txog kev siv khoom mus rau theem ceev faj. Nyob rau hauv qhov xwm txheej tam sim no, cov kev pheej hmoo thiab cov teeb meem uas ntsib los ntawm kev txhim kho cov khoom polyethylene kuj hnyav dua.
Cov pej xeem thiab kev loj hlob ntawm kev lag luam txiav txim siab qhov kev faib tawm ntawm kev siv PE. Los ntawm qhov kev xav ntawm cov cheeb tsam siv downstream, Sab Hnub Tuaj Tuam Tshoj, Sab Qab Teb Tuam Tshoj, thiab Sab Qaum Teb Tuam Tshoj yog cov cheeb tsam siv tseem ceeb rau kev siv polyethylene downstream hauv kuv lub teb chaws, thiab yuav tseem yog peb qhov saum toj kawg nkaus hauv kev siv rau lub sijhawm ntev tom ntej. Txawm li cas los xij, nrog rau kev tsim cov khoom siv tshiab tsim khoom tas mus li yav tom ntej, nws xav tias qhov sib txawv ntawm kev siv hauv peb qhov chaw siv loj yuav raug txo kom tsawg. Nws xav tias qhov no yuav cuam tshuam rau yav tom ntej kev muab khoom thiab kev thov qauv thiab kev xa khoom hauv cov cheeb tsam loj. Nws tseem tsim nyog hais tias txawm hais tias qhov sib piv ntawm kev thov downstream hauv thaj tsam sab hnub poob me dua li Sab Hnub Tuaj Tuam Tshoj, Sab Qab Teb Tuam Tshoj, thiab Sab Qaum Teb Tuam Tshoj, tsav los ntawm cov cai hauv tsev xws li "Ib Txoj Kev, Ib Txoj Kev" thiab "Kev Txhim Kho Sab Hnub Poob", kev siv polyethylene downstream hauv thaj tsam sab hnub poob yuav nce ntxiv yav tom ntej. Muaj kev cia siab nce ntxiv, tshwj xeeb tshaj yog rau cov khoom siv hauv paus tsev uas coj los ntawm cov kav dej, thiab qhov kev thov rau kev txhaj tshuaj molding thiab cov khoom rotational molding uas coj los ntawm kev txhim kho tas mus li ntawm qhov zoo ntawm lub neej yog qhov pom tseeb dua.
Tom qab ntawd, hais txog cov kev siv ntau yam hauv qab no yav tom ntej, cov kev cia siab loj npaum li cas rau cov kev xav tau tseem ceeb ntawm polyethylene hauv qab no?
Tam sim no, kev siv cov polyethylene tseem ceeb 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.
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 nrog qhov 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. Tam sim no, qhov teeb meem tseem ceeb uas cov lag luam saum toj no ntsib yog tias qhov kev loj hlob ntawm cov vaj tse tau nyob twj ywm hauv xyoo tas los no. Vim muaj cov yam xws li kev tawm tswv yim tsis zoo rau cov neeg nyob hauv kev xav noj mov uas coj 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, thiab nws tsis tshua 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 zuj zus yav tom ntej. Qhov ua tau.
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.
