BMC yog lub npe luv ntawm cov iav fiber reinforced unsaturated polyester thermosetting yas, thiab tam sim no nws yog hom siv ntau tshaj plaws ntawm cov thermosetting yas reinforced.
BMC Cov yam ntxwv thiab daim ntawv thov
BMC muaj cov khoom siv lub cev zoo, hluav taws xob thiab kho tshuab, yog li nws muaj ntau yam kev siv, xws li kev tsim cov khoom siv kho tshuab xws li cov kav dej nkag, cov hau valve, thiab cov hau manhole thiab rims. Nws kuj tseem siv dav hauv kev tsav dav hlau, kev tsim kho, rooj tog, cov khoom siv hluav taws xob, thiab lwm yam, uas xav tau kev tiv thaiv av qeeg, hluav taws kub, kev zoo nkauj thiab kev ruaj khov.
Cov yam ntxwv ua tiav BMC
1. Kev Ua Tau Zoo: BMC muaj kev ua tau zoo thiab tuaj yeem tswj tau kev ua tau zoo hauv qab qhov siab qis.
2. Kev Kho Tau: Qhov ceev kho ntawm BMC yog qhov ceev heev, thiab lub sijhawm kho yog 30-60 vib nas this / hli thaum qhov kub molding yog 135-145 ° C.
3. Tus nqi ntsws: Tus nqi ntsws ntawm BMC yog qis heev, ntawm 0-0.5%. Tus nqi ntsws kuj tseem tuaj yeem hloov kho los ntawm kev ntxiv cov khoom ntxiv raws li qhov xav tau. Nws tuaj yeem faib ua peb theem: tsis muaj ntsws, ntsws tsawg, thiab ntsws siab.
4. Kev Muaj Xim: BMC muaj xim zoo.
5. Qhov tsis zoo: lub sijhawm molding ntev heev, thiab cov khoom burr loj heev.
BMC compression molding
BMC compression molding yog ntxiv ib qho nyiaj ntawm cov tshuaj molding (agglomerate) rau hauv cov pwm uas tau ua ntej lawm, nias thiab cua sov, thiab tom qab ntawd khov thiab ua kom zoo nkauj. Cov txheej txheem tshwj xeeb yog qhov hnyav → pub mis → molding → sau (cov agglomerate nyob rau hauv qhov siab Nws ntws thiab sau tag nrho cov pwm) → kho → (kho tag nrho tom qab khaws cia ntawm qhov siab thiab kub teem rau ib lub sijhawm) → qhib cov pwm thiab tshem tawm cov khoom → sib tsoo lub burr, thiab lwm yam → cov khoom tiav.
Cov xwm txheej ntawm cov txheej txheem BMC compression molding
1. Moulding siab: 3.5-7MPa rau cov khoom ib txwm muaj, 14MPa rau cov khoom uas muaj qhov xav tau siab.
2. Kub pwm: Qhov kub pwm feem ntau yog 145 ± 5 ° C, thiab qhov kub pwm ruaj khov tuaj yeem txo qis los ntawm 5-15 ° C rau kev rhuav pwm.
3. Kev ceev ntawm pwm clamping: qhov zoo tshaj plaws pwm clamping tuaj yeem ua tiav hauv 50 vib nas this.
4. Lub sijhawm kho: Lub sijhawm kho ntawm cov khoom nrog phab ntsa tuab ntawm 3 hli yog 3 feeb, lub sijhawm kho nrog phab ntsa tuab ntawm 6 hli yog 4-6 feeb, thiab lub sijhawm kho nrog phab ntsa tuab ntawm 12 hli yog 6-10 feeb.
