Xav paub ntau ntxiv txog Composites (3) Kev Tsim Khoom- SMC
Sheet Molding Compound (SMC) yog ib hom ntawv molding compound ua los ntawm resin paste impregnated fiber los yog tws fiber ntau lev, them nrog polyethylene zaj duab xis ntawm ob sab, teej tug mus rau lub Scope ntawm prepreg khoom.
ib qho ntawm feem ntau siv molding cov ntaub ntawv nyob rau hauv lub ntiaj teb no
Hom ntawm SMC:
SMC-daim ntawv molding compound (0.63cm tuab, 1/4 nti)
BMC-Block Moulding Compound
TMC-thick sheet molding compound (5.08cm tuab, 2 nti)
Qhov zoo ntawm compression molding txheej txheem
muaj ntau lawm efficiency
qhov khoom loj yog qhov tseeb
qhov saum npoo yog du
feem ntau cov khoom uas muaj cov qauv complex tuaj yeem molded ib zaug
cov tsos thiab qhov loj ntawm cov khoom muaj zoo repeatability
yooj yim kom paub mechanization thiab automation
Disadvantages ntawm compression molding txheej txheem
Pwm tsim thiab tsim khoom yog complex
xovxwm thiab pwm peev yog siab
cov khoom loj yog txwv los ntawm cov khoom siv
feem ntau tsuas yog tsim rau kev tsim khoom loj ntawm cov khoom nruab nrab thiab cov khoom me me
Nrog rau kev txhim kho ntawm kev tshwj xeeb, automation thiab ntau lawm efficiency nyob rau hauv xyoo tas los no, tus nqi ntawm cov khoom tau raug txo kom tsis tu ncua, thiab cov Scope ntawm kev siv tau ua ntau thiab ntau dua.
Kev faib tawm ntawm cov txheej txheem compression molding (tshem tawm los ntawm lub cev lub cev ntawm cov khoom siv ntxiv thiab cov khoom siv molded)
(1) Cov khoom siv luv fiber ntau molding txoj kev
(2) Felt molding txoj kev
(3) Moulding txoj kev ntawm cov ntaub tawg
(4) Laminated molding txoj kev
(5) Winding molding txoj kev
(6) Fabric molding txoj kev
(7) Directional nteg molding txoj kev
(8) Preform molding txoj kev
(9) Daim ntawv molding compound molding txoj kev
SMC daim ntawv (daim ntawv molding compound): Nws siv unsaturated resin raws li ib tug binder rau impregnate tws fibers los yog xav, thiab thicken nws kom tau ib daim ntawv molding compound.
