Matambudziko ekufambisa, kukwira kwezvinodiwa nezvimwe zvinhu zvakaita kuti mitengo ikwire kana kuti kunonoka. Vatengesi neGardner Intelligence vane maonero akafanana.
1. Basa rose rebhizinesi revagadziri vemagirazi fiber kubva muna 2015 kusvika kutanga kwa2021, zvichibva padata kubvaGardner Uchenjeri.
Sezvo denda re coronavirus richisvika mugore rayo rechipiri, uye sezvo hupfumi hwepasi rose huri kuvhurwa zvishoma nezvishoma, ketani yekugovera magirazi pasi rose iri kutarisana nekushomeka kwezvimwe zvigadzirwa, zvichikonzerwa nekunonoka kwekutakura uye mamiriro ekuda kwemidziyo ari kuchinja nekukurumidza. Nekuda kweizvozvo, mamwe mafomati egirazi magirazi haawanikwe, zvichikanganisa kugadzirwa kwezvikamu zvakasanganiswa uye zvivakwa zvemugungwa, mota dzekutandarira uye mimwe misika yevatengi.
Sezvataurwa muNyika DzakabatanapamwedziMishumo yeComposites Fabricating IndexnaGardner UchenjeriMukuru wezvehupfumi Michael Guckes, kunyangwe kugadzirwa kwezvinhu nekutenga zvinhu zvitsva zvichidzoka,Matambudziko ekutengesa zvinhu ari kuramba aripokumusika wese wezvinhu zvakagadzirwa (uye kugadzira zvinhu) mugore idzva.
Kuti udzidze zvakawanda nezvekushomeka kwakataurwa muchikamu chekugovera magirazi, kunyanya,CWVanyori vakabvunza Guckes vakataura nevanhu vakati wandei vari muchikamu chekugadzira magirazi fiber, kusanganisira vamiririri vevatengesi vemagirazi fibers.
Vatengesi nevagadziri vazhinji, kunyanya kuNorth America, vakataura nezvekunonoka kwekugamuchira zvigadzirwa zvefiberglass kubva kune vatengesi, kunyanya zvema "multi-end rovings" (pfuti rovings, SMC rovings), mati akachekwa-chekwa uye ma "woven rovings". Uyezve, chigadzirwa chavari kugamuchira chingangove chiri pamutengo wakawedzerwa.
Sekureva kwaStefan Mohr, director webhizinesi repasi rose fibers forJohns Manville(Denver, Colo., US), izvi zvinokonzerwa nekuti kushomeka kuri kuitika muchikamu chekutengesa magirazi fiber. "Mabhizinesi ese ari kutangazve pasi rose, uye tinonzwa kuti kukura muAsia, kunyanya kumapurojekiti emotokari nezvivakwa, kwakasimba zvikuru," anodaro.
"Parizvino, vagadziri vashoma kwazvo mune chero indasitiri vari kuwana zvese zvavanoda kubva kune vatengesi," anodaro Gerry Marino, maneja mukuru wekutengesa nekushambadzira kuElectric Glass Fiber America (chikamu cheBoka reNEG, Shelby, NC, US).
Zvinonzi zvikonzero zvekushomeka uku zvinosanganisira kuwedzera kwekudiwa kwezvinhu mumisika yakawanda uye kutadza kuenderera mberi nekuda kwematambudziko ane chekuita nedenda, kunonoka kwekutakura zvinhu uye kukwira kwemitengo, uye kudzikira kwezvinotengeswa kunze kwenyika neChina.
