Dab tsi yog lub ntsiab molding txheej txheem ntawm mica board ua epoxy iav fiber board

1. Muab tes tso rau ntawm qhov chaw ntub dej

Thov tso tus neeg sawv cev tso tawm thiab txheej txheej nruab nrab-ua kua thermosetting cob nrog viscosity ntawm 0.3-0.4PaS mus rau saum npoo ntawm pwm nyob rau hauv lem (tom qab cov gel txheej yog coagulated) thiab txheej ntawm cov khoom siv fiber ntau. Cov khoom siv fiber ntau muaj qhov xav tau thiab tsis ntxhib ntxhib Muaj ntau hom ntaub qhwv (daim ntaub khij). Siv tus menyuam tuav lossis txhuam los txhuam cov tshuaj nrog cov khoom siv ua kom muaj zog, tshem tawm cov pa cua, thiab ua kom lub hauv paus txheej. Kev ua haujlwm txheej yog rov ua ntau zaus kom txog thaum tsim cov khoom tuab ntawm cov khoom. Cov tshuaj kho tau zoo ntawm chav sov vim yog cov tshuaj tiv thaiv polymerization. Ua kom sov kom nrawm kho. Tam sim no, kev teeb tsa tes yog lub hauv paus tseem ceeb hauv Suav teb, uas suav txog 80% ntawm cov khoom siv sib xyaw ua ke.

2. Resin txhaj tshuaj thiab hloov tshuaj hloov RTM molding

RTM yog kaw-pwm qis-siab molding txheej txheem. Muab cov khoom siv ua kom muaj fiber ntau nruab nrab ntawm cov pwm sab saud thiab qis dua; kaw cov pwm thiab kaw cov pwm; txhaj cov tshuaj nyob rau hauv siab; qhib cov pwm tom qab cov tshuaj kho tau zoo, thiab tshem tawm cov khoom. Ua ntej txheej txheej txheej gelation pib, cov tshuaj yuav tsum tau ntim rau hauv cov kab noj hniav pwm, thiab lub siab ua kom cov tshuaj hloov pauv sai sai rau hauv cov pwm thiab ua rau cov khoom siv fiber ntau.

3. Moulding ntawm daim ntawv SMC (ntau BMC)

Ntxiv cov thawj coj, cov tshuaj pleev xim, cov xim tso rau sab hauv, cov tshuaj tso tawm tus neeg sawv cev, cov khoom siv qis qis, cov tuab tuab, thiab lwm yam rau hauv cov tshuaj, thiab sib tov lawv los ua cov kua nplaum. Cov kua nplaum muab tso rau ntawm zaj duab xis qis ntawm chav SMC (feem ntau siv cov yas polyethylene lossis zaj duab xis nylon), thiab tib lub sijhawm, nws nyob ntawm zaj duab xis qis thiab txaws rau hauv 25-55mm iav fiber ntau, thiab tom qab ntawd nws tau npog nrog txheej ntawm zaj duab xis los ua ib daim ntawv. Sandwich yob. Khaws cov kauj rau ob peb hnub kom tuab cov ntaub ntawv kom mus txog qhov tuaj yeem tuaj yeem ua rau viscosity. SMC tau muab los ua kev thaub qab hauv ib lub xeev uas tau ntim. Cov kauj tsis raug txiav, txiav, ntsuas, muab tso rau hauv cov cua sov steel pwm platinum, nias kom khov thiab pwm, thiab tom qab ntawd cov khoom tiav yog tau txais.
