Fiberglass Mat: Nws yog cov khoom zoo li cov khoom ua los ntawm cov txheej txheem txuas ntxiv lossis txhoov tawm ntawm cov tshuaj lom neeg los ntawm kev siv tshuaj lom neeg lossis kev ua.
Kev Siv Yuav Tsum:
Txhais tes nteg-up:Tes nteg-up yog lub ntsiab txoj kev ntawm FRP ntau lawm hauv kuv lub teb chaws.Iav Fiber tws Strand Mats, Nruam mats thiab stitched mats tuaj yeem siv tau hauv kev nteg tes. Kev siv ntawm cov plooj-sib khi ua ke tuaj yeem txo cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg thiab txhim kho kev ua haujlwm ntawm tes. Txawm li cas los xij, vim hais tias lub stitchbonded mat muaj ntau cov tshuaj stitchbonding xov xwm, cov kua txiv Frp muaj ntau rab koob npuas, thiab lub ntsej muag zoo li ntxhib thiab tsis yog du. Ib qho ntxiv, cov ntaub qhwv tau muaj ib daim ntaub hnyav, thiab cov pwm cov kev pab them nyiaj luv dua li qhov txiav lev thiab cov lev txuas ntxiv. Thaum ua cov khoom lag luam nrog cov duab nyuaj, nws yog ib qho yooj yim los tsim cov voids ntawm khoov. Cov txheej txheem sab tes yuav tsum tau ua tus yam ntxwv ntawm cov khoom siv ceev infiltration tus nqi, yooj yim tua cov pa npuas, thiab mould zoo kev pab them nqi.
Pultrusion:Cov txheej txheem pultrusion yog ib qho ntawm cov ntsiab lus siv rau kev txuas ntxiv thiab plooj-khi. Feem ntau, nws yog siv hauv kev sib xyaw ua ke nrog untwisted roving. Siv cov khoom txuas ntxiv mats thiab stitched mat ua cov khoom pultruded tuaj yeem txhim kho cov hoop thiab transverse lub zog ntawm cov khoom lag luam thiab tiv thaiv cov khoom los ntawm kev tawg. Lub pultrusion txheej txheem yuav tsum tau lub mat kom muaj kev faib tawm fiber ntau, zoo hloov kho lub zog, thiab pwm ua kom zoo nkauj, thiab cov lev yuav tsum muaj qhov ntev txuas ntxiv.
RTM:Resin hloov moulding (RTM) yog lub kaw pwm tuaj pwm. Nws yog tsim ntawm ob ib nrab pwm, tus poj niam pwm thiab ua tus txiv neej pwm, ib rab phom tua, tsis muaj phom. Tus txheej txheem RTM feem ntau siv cov lev txuas ntxiv thiab plooj-khi ntau dua li cov tws strand mats. Nws yog qhov yuav tsum tau tias daim lev lev yuav tsum yooj yim kom muaj cov khoom siv hluav taws xob muaj nrog cov khaub ncaws, cov huab cua zoo, zoo tshaj plaws rau kev tshem tawm thiab zoo dua qub.
Cov txheej txheem Winding: tws mats Thiab cov mats txuas ntxiv yog feem ntau siv rau winding thiab sib sau ua resin-nplua nuj txheej tsuas yog siv los ua cov khoom siv sab hauv thiab sab nraud txheej. Cov tseev kom muaj rau cov iav fiber lev nyob rau hauv cov txheej txheem winding yog ib qho zoo ib yam li hauv txoj kev sib tw.
Centrifugal casting Moulding: tws matfeem ntau yog siv los ua cov khoom siv raw. Lub tws strand lev yog ua ntej-pw hauv pwm, thiab tom qab ntawdlub resinyog ntxiv rau hauv qhov tig qhib cov pwm kab noj hniav, thiab cov pa npuas dej tau tawm los ntawm centrifugation los ua kom cov khoom tuab. Lub laum daim yog yuav tsum muaj cov yam ntxwv ntawm kev nkag mus yooj yim thiab huab cua zoo permeability.
Tus txheej txheem ntau lawm ntawm iav Fiber nto lev txiav txim siab tias nws muaj qhov zoo ntawm cov fibers, mos muag permeability, thiab cov huab cua zoo infiltration ceev. Cov kev qhia tshwj xeeb yog li 15G / M² mus rau 100G / M². Qhov chaw thiab cov plhaub yog cov khoom tsim nyog rau Frp kav dej thiab Frp cov khoom.
