Nyob rau hauv xyoo tas los no, kev lag luam graphite pwm tau tsim los ntawm leaps thiab ciam teb, thiab cov castings npaj tau yooj yim rau daim ntawv, zoo, thiab tsis muaj residue hauv casting nws tus kheej. Yuav kom ua tau raws li cov yam ntxwv saum toj no, pwm nrog nplai graphite yuav tsum xaiv txoj cai los ua, hnub no Furuite graphite xiaobian yuav qhia rau koj txog cov yam ntxwv ntawm pwm nrog nplai graphite:
Cov yam ntxwv ntawm cov flake graphite rau pwm (DUAB 1)
Ua ntej, qhov coefficient ntawm kev ua kom sov ntawm cov pwm flake graphite yog siab. Qhov ceev txias yog ceev thiab qhov casting tuaj yeem tshem tawm sai sai siv cov pwm graphite.
Ob, nrog qee yam lub zog kho tshuab. Thaum qhov kub ntawm casting siab, cov pwm yuav tsum tswj tau cov duab zoo li qub, kom cov casting tuaj yeem ua tau zoo.
Peb, cov coefficient ntawm thermal expansion me me, qhov cuam tshuam rau kev ua haujlwm ntawm cov cua sov yog qhov muaj zog. Cov duab pwm thiab qhov loj me hloov me me thaum nws raug cua sov thiab txias, yog li nws yooj yim kom khaws qhov tseeb ntawm qhov casting.
Plaub, muaj kev ua haujlwm zoo.
Tsib, graphite oxide ncaj qha mus rau hauv cov roj volatilization, lub workpiece tsis tuaj yeem tawm hauv cov residue.
