Peb tau mus rau South Africa thiab Kenya los koom nrog ob qhov kev nthuav qhia thaum Lub Yim Hli thiab Cuaj Hli, 2023. Ua tiav cov txiaj ntsig zoo heev. Peb pom cov kab lis kev cai hauv zos thiab lub neej niaj hnub ntawm cov neeg nyob hauv. Africa, raws li kev lag luam tom ntej yuav tawm mus, muaj peev xwm loj thiab muaj zog.
Cov neeg siv khoom tsis yog los ntawm South Africa thiab Kenya, tab sis los ntawm lawv lub tebchaws nyob sib ze, xws li, Namibia, Mozambique, Zimbabwe, Tanzania, thiab lwm yam.
Peb tau nthuav tawm cov khoom hauv qab no tsim los ntawm peb lub tuam txhab:
Yas HDPE loj inch yeeb nkab ua tshuab
WPC qhov rais thiab qhov rooj extrusion tshuab
Plastics Industry Overview in Africa
Yas yog cov khoom siv los ntawm cov khoom siv hluavtaws lossis cov khoom siv ntuj tsim los ua cov khoom tseem ceeb, nrog rau ntau yam khoom siv ntxiv, thiab ua tiav rau hauv cov duab. Yas muaj qhov zoo ntawm lub teeb yuag, siab zog, corrosion kuj, zoo rwb thaiv tsev, thiab ua tau yooj yim. Nws yog dav siv hauv kev tsim kho, ntim khoom, kev thauj mus los, hluav taws xob, kev kho mob thiab lwm yam.
Raws li cov khoom siv thiab kev siv cov yas, lawv tuaj yeem muab faib ua ob pawg: cov yas dav dav thiab cov yas engineering. Cov yas dav dav hais txog cov yas uas muaj nqi qis dua thiab dav siv ntau yam, feem ntau suav nrog polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), thiab lwm yam. Engineering plastics xa mus rau cov yas uas muaj cov cuab yeej siv siab, ua haujlwm kub. , tshuaj tiv thaiv thiab lwm yam khoom tshwj xeeb. Lawv tsuas yog siv los hloov cov hlau lossis lwm yam khoom siv los ua cov khoom lag luam lossis cov plhaub. Feem ntau suav nrog polyamide (PA), polycarbonate (PC), thiab lwm yam.
Yas kev lag luam kev loj hlob tiam sis
1. Kev ua lag luam muaj kev cia siab dav thiab kev lag luam yuav loj hlob ntxiv
Kev lag luam plastics yog ib feem tseem ceeb ntawm kev lag luam cov khoom siv tshuaj tshiab, thiab nws tseem yog thaj chaw uas muaj peev xwm loj tshaj plaws thiab kev loj hlob.
Thaum cov ntawv thov kev lag luam yooj yim uas ua tau raws li cov kev xav tau ntawm tib neeg muaj kev loj hlob tsis tu ncua, cov ntawv thov qib siab tau maj mam nthuav dav. Kev lag luam khoom lag luam yas tseem nyob rau theem kev loj hlob, thiab kev hloov pauv thiab kev kho dua tshiab tau nce mus ntxiv. Txoj kev loj hlob ntawm kev hloov cov hlau nrog yas thiab hloov ntoo nrog yas muab kev lag luam dav dav rau kev txhim kho cov khoom lag luam yas.
2. Kev txhim kho dislocation thiab kev cog qoob loo sib sib zog nqus ntawm ntu kev lag luam
Kev lag luam khoom lag luam yas muaj ntau qhov chaw qis qis, thiab cov khoom siv yas sib txawv muaj qhov sib txawv heev rau cov tuam txhab tsim khoom 'R & D muaj peev xwm, thev naus laus zis, txheej txheem tsim khoom thiab kev tswj hwm qib. Muaj ntau hom khoom siv yas, kev siv tshuab loj, thiab ntau yam kev siv. Kev lag luam xav tau yog loj thiab muab faib rau hauv kev lag luam downstream sib txawv. Feem ntau ntawm cov koom ua lag luam yog cov lag luam me thiab nruab nrab. Muaj overcapacity nyob rau hauv cov khoom qis kawg, kev sib tw hnyav, thiab kev ua lag luam tsawg.
Raws li qhov xwm txheej no, peb lub tuam txhab txuas ntxiv nqis peev hauv kev tshawb fawb thiab kev tsim kho los tsim cov khoom lag luam uas haum rau cov kev xav tau ntawm ntau pawg neeg siv khoom.
NojPET ntawv extrusion tshuabua piv txwv, peb muaj cov khoom siv nrog cov khoom sib txawv thiab kev teeb tsa rau cov neeg siv khoom xaiv, thiab tuaj yeem kho raws li cov neeg siv khoom xav tau.
PET ntawv extrusion tshuabQhov zoo:
Hanhai txhim kho qhov sib npaug ntxaib ntsia hlau extrusion kab rau PET daim ntawv, cov kab no nruab nrog degassing system, thiab tsis tas yuav ziab thiab crystallizing chav tsev. Cov kab extrusion muaj cov khoom siv hluav taws xob tsawg, cov txheej txheem tsim khoom yooj yim thiab kev saib xyuas yooj yim. Lub segmented ntsia hlau qauv tuaj yeem txo qhov viscosity poob ntawm PET resin, symmetrical thiab nyias-phab ntsa calender rau cov menyuam ua kom txias txias thiab txhim kho lub peev xwm thiab daim ntawv zoo. Ntau yam khoom noj pub noj tuaj yeem tswj tau qhov feem pua ntawm cov khoom siv nkauj xwb, cov khoom siv rov ua dua tshiab thiab cov khoom lag luam zoo meej, daim ntawv yog dav siv rau kev lag luam ntim thermoforming.
