Hlau silicon hmoovtxheej txheem ntau lawm
Kev tsim cov txheej txheem ntawm silicon hmoov tuaj yeem piav qhia yooj yim li crushing thiab sib tsoo los ntawm silicon blocks, tab sis tau txais cov hmoov uas yuav tsum tau purity thiab particle loj tis yog qhov nyuaj dua.
The first step: raw material selection, which is related to the purity of the final silicon powder. The silicon block used to make the powder is approximately >100 hli.
Kauj Ruam 2: Txiav cov silicon blocks rau hauv cov me me, ua ntej rau hauv 5cm silicon blocks, thiab tom qab ntawd siv cov menyuam crusher thiab linear screen kom tau cov khoom ntawm li 3 hli. Rov ua kauj ruam no rau<3mm particles.
Kauj Ruam 3: Kev faib tawm thawj theem ntawm huab cua ntws, los ntawm -30 mesh mus rau qib thib ob
Kauj Ruam 4: Lub hom phiaj dav hlau sib tsoo ntawm +30 mesh hais hauv kauj ruam 3, los ntawm -30 mesh mus rau theem thib ob kev faib tawm
Kauj Ruam 5: Pib qhov kev faib tawm thib ob los ntawm -450 cov khoom mesh, thiab siv cov hnab lim dej los khaws cov khoom. Rau cov khoom ntawm 30-450 mesh, siv lub tshuab magnetic muaj zog kom tshem tawm cov hlau.
Kauj Ruam 6: Lub voj voog vibrating sieve yuav siv cov khoom tau txais nyob rau hauv kauj ruam 5. Qhov luaj li cas ntawm cov silica hmoov peb tau txais ntawm no yog txawv. A. Sau -325 mesh rau ntub laser particle loj faib. b. Lwm qhov yuav tsum tau muaj particle loj, sau, thiab kuaj. C. +120 mesh particles nkag mus rau theem 4. Koj tuaj yeem hloov qhov mesh mesh ntawm cov kauj ruam no kom tau txais qhov xav tau particle loj ntau yam. Yog tias qhov loj me yog nqaim, koj tuaj yeem xaiv qhov kev tshuaj ntsuam tsim nyog ua ke ntawm no, ua qee qhov kev sim, thiab koj yuav pom cov qauv tsim nyog. Muaj ntau ntau txoj haujlwm yuav tsum tau ua ntawm no, uas yog vim li cas cov khoom siv nrog PSD nruj yuav raug nqi ntau dua.
Kauj Ruam 7: Purification. Lub hom phiaj ntawm cov kauj ruam no yog tshem tawm cov ntsiab lus xws li Ca thiab Al uas tuaj yeem raug tshem tawm los ntawm cov kua qaub.
Kauj Ruam 8: Qhuav Ntim Cov Kauj Ruam 1 thiab 7 yog kom tau cov khoom mus rau qhov xav tau purity yog tias koj xav tau PSD nqaim heev.
ZhenAn muaj kev paub dhau los hauv kev tswj PSD. Qhov no yog qhov zoo nkauj zoo ib txwm faib nkhaus los ntawm ib qho ntawm peb txoj haujlwm ua tiav.
