300g Chopped Strand Mat
Txiav strand lev(tseem hu ua CSM) yog qhov feem ntau siv cov khoom siv ntxiv.
Txiav strandsntawm fibersglass yog randomly faib thiab sib koom ua ke los tsim cov tws strand lev. Chopped strand lev tuaj yeem impregnated nrog resin thiab yog ib qho kev txhawb nqa rau cov khoom siv FRP ib txwm muaj lossis pwm.
Vim nws qhov kev ua tau zoo qis dua li lwm cov khoom siv ntxiv (iav ntaub, carbon fiber, aramid fiber, thiab lwm yam), chopped strand lev feem ntau tsis siv los ua cov tawv nqaij txheej hauv cov ntaub ntawv sib xyaw ua ke, tab sis nws tseem yog feem ntau siv hauv cov khoom thiab dav. siv hauv kev tsim khoom ntawm FRP cov khoom tsim pwm.
Vim li cas thiaj siv hmoov daim ntawv?
Ib yam dab tsi yuav tsum tau ua kom sib txuas cov tawg tawg tawg ua fibersglass ua ke. Cov tshuaj emulsions rau kev sib txuas cov hlua khi hlua khi yog soluble los ntawm polyester lossis yas resins; Txawm li cas los xij, epoxy resins tsis yaj lub emulsion, uas txhais tau hais tias cov tws strand fibers tseem nyob ua ke rau ib leeg, ua rau tws strand lev tsis tshua muaj lamination.
Hmoov-hom chopped strand lev tuaj yeem siv rau epoxy resin, thiab nws cov hmoov nplaum tsis tas yuav yaj zoo li emulsion nplaum, yog li nws yog qhov yuav tsum tau ua rau epoxy laminated pwm lossis khoom.
Thaum qhov kub thiab txias poob rau lub caij ntuj no, tib cov resin yuav thicken, ua rau cov dej tsis zoo ntawm cov resin, tab sis cov hmoov-hom chopped strand lev yog fluffy, uas daws qhov teeb meem no tag nrho, tshwj xeeb tshaj yog nyob rau ntawm cov ces kaum uas nws yooj yim dua mus txuas rau. pwm.
300g hmoov-hom tws strand lev, haum rau tag nrho cov resin systems, xws li epoxy, polyester, yas thiab phenolic resin; yog li yog tias koj tsis paub tseeb tias qhov twg yog qhov zoo tshaj rau koj, lossis tsuas yog siv ib hom chopped strand lev, ces Thov siv hom ntawd.
