Dab tsi yog yam uas txiav txim siab kev ua ntawm silicon hlau hmoov?
Cov kev ua ntawm silicon hlau hmoov tau los ntawm kev sib txawv pob milling txoj kev sib txawv, thiab cov yam uas txiav txim siab cov kev ua yog raws li hauv qab no: microstructure, thaj tsam tshwj xeeb thaj tsam, faib cov loj me me, kev tiv thaiv saum npoo thiab cov hlau siv hauv cov khoom siv.
(1) Microstructure: lub silicon uas nws cov tshuaj sib xyaw ua kom tau raws li qhov ntsuas xav tau muaj microstructure zoo dua rau hauv cov txheej txheem ua kom zoo, uas ua kom nws muaj kev ua haujlwm zoo dua tuaj koom nrog qhov tshuaj tiv thaiv, uas yog, nws qhov ntuj lossis qhov ntuj. Qhov kev puas tsuaj ntawm lub microstructure ntuj yuav tsum tsis txhob muaj sijhawm tsawg kawg thaum sib tsoo, thiab kev deformation ntawm cov pab pawg thiab cov pab pawg yuav tsum txo qis, yog li feem ntau ntawm silicon hlau hmoov (ntau dua 99.8%) tseem khaws nws cov qub microstructure. Ntawm plaub txoj hauv kev teev, xuas nrig ntaus nrig thiab tig rov qab yog qhov txheej txheem zoo dua. Vim tias cov roj silicon tau tawg rau saum huab cua, nws tau tawg raws cov kab txuas tsis muaj zog ntawm lub cev, tsis muaj cov txheej txheem deformation los ntawm kev tawg, sib tsoo, thiab lwm yam.
(2) Thaj chaw tshwj xeeb: thaj chaw thaj tsam ntawm hmoov yog thaj tsam saum npoo ntawm chav tsev loj, m2 / g, yog qhov ntsuas tseem ceeb ntawm kev muaj peev xwm koom nrog tshuaj lom neeg. Qhov tshwj xeeb hauv cheeb tsam ntawm cov hlau silicon hmoov yog qhov loj dua, qhov kev hloov pauv yog sai dua, qhov kev tawm tsam yog ua tiav ntau dua, kev siv cov khoom siv silicon muaj ntau dua, qhov cuam tshuam cheeb tsam ntws txawv yog qhov zoo dua, kev siv silicon tsawg dua, uas qhia nws qhov kev ua haujlwm siab Cov. Yog li no, thaj chaw thaj tsam tau dhau los ua qhov ntsuas tseem ceeb ntawm silica hmoov cov haujlwm. Lub hmoov ua hmoov muaj thaj chaw zoo dua qub.
(3) Kev faib tawm qhov loj me: qhov kev sib cais ncaj qha yog maj mam ua tiav nyob rau hauv lub xeev qhov dej, qhov khoom tawg me me hloov maj mam hloov, cov nplaim hloov tas li, qhov tshuaj tiv thaiv yog txhua yam, kev noj tshwj xeeb ntawm silicon kuj txo qis. Yog li ntawd, lub particle loj ntawm silicon hlau hmoov yuav tsum sib phim rau cov qib loj particle kom tau txais cov txiaj ntsig zoo dua qub thiab tsim cov qauv sib xyaw kom zoo dua cov khoom faib tawm. Yog li ntawd, txoj kev sib tsoo yuav tsum xyuas kom meej tias cov particle loj muaj pes tsawg leeg tuaj yeem hloov kho thiab qhov txiaj ntsig yog qhov siab. Piv txwv li, thaum lub particle loj ntawm 1T silicon hmoov yog li ntawm 85% lossis siab dua, nws yog qhov tsim nyog tshuaj tiv thaiv ntau dua. Qhov no yog cov ntaub ntawv raw khoom ntawm silicon hlau hmoov siv hauv lub txaj fluidized ntawm 100,000 t / a organosilicon coarse monomer. (4) kev tiv thaiv saum npoo: kev tsim cov khoom tiav silicon hmoov tsim nyog nyob rau hauv txoj kab nrog cov cai ntawm qhov zoo thiab qhov ntsuas me me, qhov saum npoo xav tau kev tiv thaiv nquag
