Dab tsi yog qhov txawv ntawm iav fiber reinforced yas molding cov ntaub ntawv smc / bmc / dmc molding plastics? SMC molding (tseem hu ua xovxwm molding lossis compression molding) yog kev ua haujlwm uas cov hmoov nplej, granular lossis fibrous plastics yog thawj zaug muab tso rau hauv pwm kab noj hniav ntawm molding kub, thiab tom qab ntawd cov pwm kaw yog pressurized los tsim thiab kho lawv. Moulding tuaj yeem siv rau thermosetting plastics, thermoplastics thiab cov khoom siv roj hmab.
Lub ntsiab tsis zoo:
(1) Nyob rau hauv tag nrho cov txheej txheem tsim, lub voj voog tsim yog ntev, qhov ua tau zoo yog tsawg, thiab nws muaj kev noj qab haus huv zoo rau cov neeg ua haujlwm.
(2) Nws tsis haum rau molding complex khoom nrog kev nyuaj siab, sab slopes los yog qhov me me.
(3) Nyob rau hauv cov txheej txheem tsim, nws yog ib qho nyuaj rau tag nrho cov pwm, thiab muaj ib tug tej yam kev thov.
(4) Thaum kawg ntawm cov txheej txheem kho, cov khoom sib txawv muaj qhov sib txawv nruj, uas muaj kev cuam tshuam rau cov khoom lag luam.
(5) Rau cov khoom uas muaj qhov siab qhov tseeb yuav tsum tau (tshwj xeeb tshaj yog rau cov kab noj hniav ntau), cov txheej txheem yog me ntsis luv.
(6) Lub flash ntawm cov khoom kawg yog tuab, thiab cov haujlwm ntawm kev tshem tawm flash yog loj.
(7) Qhov tsis zoo ntawm molding yog qhov kev tsim pwm yog qhov nyuaj, kev nqis peev yog loj, thiab txwv los ntawm cov xovxwm, nws yog qhov tsim nyog tshaj plaws rau kev tsim cov khoom me me thiab nruab nrab.
BMC kev txhawb nqa
Cov khoom siv feem ntau siv hauv cov khoom siv molding feem ntau suav nrog cov iav fiber ntau txiav hlau, untwisted roving, twisted roving, nruam iav fiber ntau, iav fiber ntau, iav fiber ntau, thiab lwm yam, thiab qee cov khoom tshwj xeeb siv asbestos xav, asbestos ntaub. (daim ntaub), asbestos ntawv, siab silica fiber, carbon fiber Organic fiber (xws li aramid fiber, nylon fiber, thiab lwm yam) thiab ntuj fiber (xws li linen, paj rwb ntaub, boiled ntaub, tsis boiled ntaub, thiab lwm yam). Qee zaum ob lossis ntau qhov sib xyaw fiber ntau yog siv los ua cov khoom siv ntxiv.
DMC hluavtaws cob
Cov khoom siv molding siv rau cov khoom sib xyaw ua ke yuav tsum muaj cov khoom siv hluavtaws muaj: ① zoo wetting khoom rau cov khoom siv ntxiv, thiaj li tsim tau ib daim ntawv cog lus zoo ntawm qhov sib txuas ntawm cov khoom siv hluavtaws thiab cov khoom siv ntxiv; ② Nws muaj qhov zoo viscosity thiab fluidity zoo, thiab tuaj yeem sau tag nrho cov kab noj hniav nrog cov khoom siv ntxiv hauv qab nias; ③ Nws muaj qhov tsim nyog curing ceev nyob rau hauv cov txheej txheem nias, tsis muaj by-products los yog tsawg dua by-products thaum lub sij hawm kho, thiab lub ntim shrinkage yog me me; ④ Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom pwm. Raws li kev xaiv cov khoom siv saum toj no, cov khoom siv hluavtaws muaj xws li cov khoom siv tsis zoo polyester, epoxy resin, phenolic resin, vinyl resin, furan resin, silicone resin, polybutadiene resin, allyl ester, melamine resin, polyimide resin, thiab lwm yam. molded khoom ncav cuag qhov kev ua tau zoo Performance index, tom qab xaiv cov resin hom thiab hom, cov ntaub ntawv sib koom tes, fillers thiab pigments yuav tsum tau xaiv.
