Cov teeb meem kev thauj mus los, kev thov khoom nce ntxiv thiab lwm yam ua rau cov nqi siab dua lossis qeeb dua. Cov neeg muab khoom thiab Gardner Intelligence sib koom lawv cov kev xav.
1. Kev ua lag luam tag nrho ntawm cov chaw tsim khoom siv iav fiber txij xyoo 2015 txog rau thaum ntxov xyoo 2021, raws li cov ntaub ntawv los ntawmGardner Kev Txawj Ntse.
Thaum tus kab mob coronavirus kis thoob plaws ntiaj teb nkag mus rau nws lub xyoo thib ob, thiab thaum lub ntiaj teb kev lag luam maj mam rov qhib dua, cov khoom siv fiber iav thoob ntiaj teb tab tom ntsib kev tsis txaus ntawm qee yam khoom, vim yog kev xa khoom qeeb thiab qhov chaw thov kev hloov pauv sai. Yog li ntawd, qee cov qauv fiber iav tsis txaus, cuam tshuam rau kev tsim cov khoom sib xyaw thiab cov qauv rau cov tsheb thauj khoom hauv hiav txwv, cov tsheb ua si thiab qee lub khw muag khoom siv.
Raws li tau hais tseg hauvCompositesWorldlub hliCov ntawv qhia txog Composites Fabricating Indexlos ntawmGardner Kev Txawj NtseTus Thawj Coj Saib Xyuas Kev Lag Luam Michael Guckes, txawm tias kev tsim khoom thiab kev txiav txim tshiab rov zoo los,cov teeb meem ntawm cov khoom xa tuaj tseem niaj hnub muajthoob plaws tag nrho cov khoom sib xyaw (thiab kev tsim khoom feem ntau) kev lag luam mus rau hauv lub xyoo tshiab.
Yog xav paub ntxiv txog cov teeb meem tsis txaus hauv cov khoom siv fiber ntau,CWcov neeg kho xov xwm tau kos npe nrog Guckes thiab tau tham nrog ntau qhov chaw raws li cov khoom siv iav fiber, suav nrog cov neeg sawv cev ntawm ntau tus neeg muab khoom iav fiber.
Muaj ntau tus neeg faib khoom thiab cov chaw tsim khoom, tshwj xeeb tshaj yog nyob rau hauv North America, tau tshaj tawm tias lawv tau txais cov khoom fiberglass qeeb los ntawm cov neeg muab khoom, tshwj xeeb tshaj yog rau ntau qhov kawg rovings (phom rovings, SMC rovings), chopped strand lev thiab woven rovings. Ntxiv mus, cov khoom uas lawv tau txais yuav muaj tus nqi nce ntxiv.
Raws li Stefan Mohr, tus thawj coj ua lag luam ntawm cov fibers thoob ntiaj teb rauJohns Manville(Denver, Colo., Tebchaws Meskas), qhov no yog vim muaj kev tsis txaus thoob plaws hauv cov khoom siv fiber iav. "Txhua lub lag luam rov pib dua thoob ntiaj teb, thiab peb xav tias kev loj hlob hauv Asia, tshwj xeeb tshaj yog rau cov haujlwm tsheb thiab kev tsim kho vaj tse, muaj zog heev," nws hais.
"Tam sim no, muaj ob peb lub tuam txhab tsim khoom hauv txhua qhov kev lag luam tau txais txhua yam uas lawv xav tau los ntawm cov neeg muag khoom," Gerry Marino, tus thawj coj ntawm kev muag khoom thiab kev lag luam ntawm Electric Glass Fiber America (ib feem ntawmPawg NEG, Shelby, NC, Tebchaws Meskas).
Cov laj thawj rau qhov tsis txaus suav nrog kev thov nce ntxiv hauv ntau lub khw thiab cov khoom xa tuaj uas tsis tuaj yeem ua raws li vim muaj teeb meem cuam tshuam nrog tus kab mob sib kis, kev thauj mus los qeeb thiab cov nqi nce siab, thiab kev xa khoom tawm hauv Suav teb txo qis.
