Dab tsi ntawm FRP cov khoom tsim nyog rau ua Chopped Strand Mat (CSM)?
Fiberglass tws strand lev(CSM) yog thawj cov khoom siv tsis yog fiberglass reinforcement, cov khoom siv dav siv ntau tshaj plaws hauv FRP (Fiberglass Reinforced Plastic) tes nteg- txheej txheem. Nws kuj tseem siv tau rau hauv qee qhov txheej txheem molding xws li RTM (Reinforced Metal Transform), winding, molding, nruam daim ntawv fabrication, thiab centrifugal casting. Cov ntawv thov ib txwm muaj xws li nkoj, tsheb, thiab tsheb ciav hlau qhov chaw, corrosion- tiv thaiv lub tank, ntim, tank dej, thiab cov ntawv corrugated. Nyob rau hauv ntau yam loj - nplai tes nteg- li FRP cov khoom, CSM yog siv ib txhij nrog untwisted roving woven ntaub. Qhov tsis yog -kev taw qhia kev faib tawm ntawm chopped strands nyob rau hauv CSM them rau qhov tsis muaj warp thiab weft tis nyob rau hauv roving woven ntaub, thaum tseem ho txhim kho lub interlaminar shear zog ntawm cov khoom FRP.
CSM kab yog cov khoom loj ntawm cov khoom siv hauv fiberglass manufacturing nroj tsuag. Qhov dav ntawm cov lev ua los ntawm cov kab no feem ntau yog li ntawm 1.27 txog 4.5 meters. Cov kab loj tsis tsuas yog muab cov khoom tso tawm siab thiab kev ua haujlwm zoo, tab sis kuj tsim cov mats zoo ib yam. Qhov dav ntawm cov ntaub ntawv lev tuaj yeem raug txiav ntawm cov kab ntau lawm raws li cov neeg siv khoom xav tau, uas ua rau muaj ntau yam khoom lag luam hloov tau. Yog li ntawd, loj- nplai tws strand lev (CSM) cov cav tov yog nrov ntawm fiberglass manufacturers. CSM cov khoom lag luam muaj nyob rau hauv g / m² qib ntawm 200, 230, 300, 380, 450, 600, thiab 900 g / m², nrog rau qhov ntau tshaj plaws yog 300-600 g / m².
Tom qab ua tiav rau hauv fiberglass reinforced yas (FRP), tws strand lev muaj kwv yees li 30% fiberglass. Vim hais tias cov fiberglasss nyob rau hauv tws strand lev tsis tas li thiab cov ntsiab lus fiber ntau nyob rau hauv txhua txheej yog tsawg, laminates ua los ntawm cov khoom no muaj zog dua. Txawm li cas los xij, nws kuj muaj qhov zoo xws li dej nruj, zoo resin nkag mus, muaj zog interlayer adhesion, zoo nkauj tiav cov khoom, tsis yog - anisotropic zog, yooj yim ntawm daim ntawv thov ntawm complex nto, thiab tus nqi qis. Nws yog feem ntau siv nyob rau hauv txheej txheej sab nraud tam sim ntawd nyob ib sab ntawm lub tsho gel thiab hauv nruab nrab cov khaubncaws sab nraud povtseg uas khoov kev ntxhov siab tsawg.
