Cov teeb meem kev thauj mus los, kev xav tau nce ntxiv thiab lwm yam tau ua rau cov nqi siab dua lossis qeeb.Cov neeg muab khoom thiab Gardner Intelligence qhia lawv qhov kev xav.
1. Kev ua lag luam tag nrho ntawm cov tuam txhab iav fiber ntau los ntawm 2015 txog thaum ntxov 2021, raws li cov ntaub ntawv los ntawmGardner txawj ntse.
Raws li tus kabmob kis tus kabmob kis mus rau nws xyoo thib ob, thiab raws li kev lag luam thoob ntiaj teb maj mam rov qhib dua, thoob ntiaj teb iav fiber ntau cov saw hlau tau ntsib kev tsis txaus ntawm qee yam khoom, tshwm sim los ntawm kev xa khoom qeeb thiab qhov chaw xav tau ceev ceev.Yog li ntawd, qee cov iav fiber ntau hom yog nyob rau hauv cov khoom luv luv, cuam tshuam rau kev tsim cov khoom sib xyaw thiab cov qauv rau cov tubrog nkoj, cov tsheb ua si thiab qee cov neeg siv khoom lag luam.
Raws li tau sau tseg hauvCompositesWorldyog txhua hliComposites Fabricating Index qhialos ntawmGardner txawj ntseTus Thawj Fwm Tsav Tebchaws Michael Guckes, txawm tias kev tsim khoom thiab kev txiav txim tshiab rov qab los,kev sib tw ntawm cov saw hlau txuas ntxiv musthoob plaws tag nrho cov khoom sib xyaw (thiab kev tsim khoom hauv kev lag luam) rau xyoo tshiab.
Txhawm rau kawm paub ntau ntxiv txog kev tshaj tawm tsis txaus hauv cov iav fiber ntau cov saw hlau tshwj xeeb,CWCov kws kho mob tau txheeb xyuas nrog Guckes thiab tau hais rau ntau qhov chaw raws cov iav fiber ntau cov saw hlau, suav nrog cov neeg sawv cev ntawm ntau lub iav fiber ntau.
Ntau tus neeg xa khoom thiab cov neeg tsim khoom, tshwj xeeb tshaj yog nyob rau hauv North America, tau tshaj tawm qeeb hauv kev tau txais cov khoom siv fiberglass los ntawm cov neeg muag khoom, tshwj xeeb tshaj yog rau ntau qhov kawg rovings ( phom rovings, SMC rovings), tws strand lev thiab woven rovings.Tsis tas li ntawd, cov khoom uas lawv tau txais yuav yog tus nqi nce ntxiv.
Raws li Stefan Mohr, tus thawj coj ua lag luam ntawm ntiaj teb fibers rauJohns Manville(Denver, Colo., Teb Chaws Asmeskas), qhov no yog vim muaj kev tsis txaus nyob thoob plaws hauv cov iav fiber ntau."Txhua lub lag luam tau rov pib dua thoob ntiaj teb, thiab peb paub tias kev loj hlob hauv Asia, tshwj xeeb tshaj yog rau kev tsim tsheb thiab kev tsim kho vaj tse, muaj zog heev," nws hais.
"Tam sim no, tsawg tus tuam txhab lag luam hauv ib qho kev lag luam tau txais txhua yam lawv xav tau los ntawm cov neeg muag khoom," sau tseg Gerry Marino, tus thawj coj ntawm kev muag khoom thiab kev lag luam ntawm Electric Glass Fiber America (ib feem ntawmNEG Group, Shelby, NC, USA).
Cov laj thawj rau qhov tsis txaus ntseeg tau tshaj tawm suav nrog kev thov nce hauv ntau lub lag luam thiab cov khoom lag luam uas tsis tuaj yeem khaws tau vim muaj teeb meem cuam tshuam txog kev sib kis, kev thauj mus los qeeb thiab nce nqi, thiab txo qis kev xa tawm hauv Suav.
