Kev Taw Qhia Txog Cov Khoom Siv Silicon Dub Thiab Lawv Daim Ntawv Thov Hauv Sandblasting
Silicon dubyog ib yam khoom siv silicon ua haujlwm nrog cov qauv nto tshwj xeeb, hu ua nws lub peev xwm nqus lub teeb muaj zog heev thiab cov qauv micro-nano nto tshwj xeeb. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm kev kho qhov tseeb ntawm qhov chaw thiab cov khoom siv ua tau zoo hauv kev tsim khoom siab, silicon dub tau siv dav hauv photovoltaics, optoelectronics, semiconductors, optical component manufacturing thiab lwm yam teb nrog nws cov khoom zoo heev thiab tshuaj lom neeg. Tib lub sijhawm, silicon dub tau maj mam nkag mus rau hauv kev lag luam sandblasting nto thiab tau dhau los ua ib hom khoom siv sandblasting tshiab nrog kev ua tau zoo heev.
Ⅰ. Cov yam ntxwv tseem ceeb ntawm cov silicon dub
Cov silicon dub yog tsim los ntawm kev kho cov nplaim silicon los ntawm ntau yam kev siv tshuab micro-nano (xws li reactive ion etching, metal-assisted chemical etching, laser-induced etching, thiab lwm yam). Nws qhov chaw muaj cov qauv cone lossis columnar ntom ntom, uas tuaj yeem txo qhov kev cuam tshuam ntawm lub teeb. Qhov kev cuam tshuam hauv qhov pom ntawm cov kab ze-infrared tuaj yeem tsawg dua 1%, yog li nws yog xim dub tsaus nti.
Cov silicon dub tsis yog tsuas yog muaj cov khoom zoo heev xwb, tab sis kuj muaj qhov zoo ntawm kev tawv siab, kev ntshiab siab, kev hnav tsis kam, thiab kev tiv thaiv corrosion. Nws cov qauv particle muaj zog thiab haum rau ntau lub voj voog nyob rau hauv cov xwm txheej ceev ceev. Nws ua tau zoo dua hauv kev xuab zeb dua li cov khoom siv abrasives ib txwm muaj xws li dawb corundum, xim av corundum, quartz xuab zeb, thiab lwm yam.
Ⅱ. Cov txiaj ntsig ntawm cov silicon dub hauv kev xuab zeb
Kev siv xuab zeb yog ib txoj kev kho qhov chaw uas siv cov xuab zeb ceev ceev los cuam tshuam rau qhov chaw kom ua tiav kev ntxuav, tshem tawm cov txheej oxide, kev ntxhib lossis cov teebmeem kho kom zoo nkauj. Raws li cov khoom siv abrasive ua tau zoo, cov silicon dub muaj qhov zoo pom tseeb hauv kev siv xuab zeb:
1. Cov nyhuv zoo thiab sib xws ntawm qhov chaw
Cov qauv geometric ntawm cov khoom me me silicon dub yog ib txwm thiab cov morphology ruaj khov. Tom qab txau, nws tuaj yeem tsim cov nyhuv matte sib xws thiab sib xws ntawm qhov chaw ntawm cov khoom ua haujlwm. Cov nyhuv kho no yog qhov tshwj xeeb tshaj yog rau cov khoom xws li iav kho qhov muag, lub tsev lens, cov khoom siv aluminium alloy, thiab lwm yam uas muaj qhov xav tau siab heev rau qhov sib xws ntawm qhov chaw thiab tsos.
2. Kev ua kom tawv thiab cuam tshuam tsis zoo
Qhov Mohs hardness ntawm cov silicon dub yog siab txog li 8.5 lossis siab dua, qhov tawg ntawm qhov chaw thaum lub sijhawm xuab zeb yog qis, thiab lub neej ua haujlwm ntev. Piv nrog cov xuab zeb quartz lossis cov hlaws iav, cov xuab zeb silicon dub ua haujlwm tau zoo dua thiab muaj lub zog cuam tshuam muaj zog dua, thiab tuaj yeem ua tiav kev ntxuav tob thiab roughening hauv lub sijhawm luv luv.
3. Kev huv siab thiab kev tiv thaiv ib puag ncig
Qhov purity ntawm cov silicon dub feem ntau yog siab tshaj 99%, thiab nws tsis muaj cov khoom tsis zoo xws li silicon dawb lossis cov hlau hnyav. Nws muaj cov plua plav tsawg hauv lub chaw ua haujlwm xuab zeb thiab tshwj xeeb tshaj yog rau kev siv hauv kev lag luam huv siab xws li cov khoom siv hluav taws xob, cov khoom siv kho mob, thiab cov ntim khoom semiconductor. Tib lub sijhawm, nws cov duab me me ruaj khov, cov hmoov av tsim me me, thiab nws muaj kev nyab xeeb dua rau kev noj qab haus huv ntawm cov neeg teb xov tooj.
4. Siv tau dua thiab tswj tau tus nqi
Vim nws qhov nyuaj siab thiab kev ruaj khov ntawm cov qauv, cov silicon dub tseem tuaj yeem tswj tau qhov zoo ntawm kev txau tom qab ntau lub voj voog, txo cov khoom poob ntau heev. Hauv cov khoom siv xuab zeb loj loj, cov silicon dub qhia tau tias muaj kev lag luam zoo dua.
Ⅲ. Cov cheeb tsam siv ib txwm muaj
Cov khoom siv xuab zeb dub silicon tau siv dav hauv cov teb hauv qab no:
Kev kho kom zoo nkauj ntawm qhov chaw kho vajtse: xws li lub xov tooj ntawm tes nruab nrab, lub plhaub phau ntawv sau, lub plhaub ntse saib thiab lwm yam khoom siv txhuas;
Kev kho kom zoo nkauj iav kho qhov muag: siv rau lub lens, lim, qhov rai kho qhov muag matte thiab kho kom zoo nkauj;
Cov khoom siv rau kev tsav dav hlau thiab tub rog: tshem tawm cov txheej oxide yam tsis hloov qhov loj me kom txhim kho qhov nplaum ntawm cov txheej;
Kev txiav cov nplaim ntawm pob khoom hluav taws xob: txhim kho qhov tseeb ntawm cov ntim khoom thiab kev sib txuas ntawm qhov interface;
Cov khoom siv ceramic thiab cov khoom sib xyaw ua ke micro-sandblasting: kev kho qhov ntxhib ntawm qhov chaw kom txhim kho lub zog sib txuas.
Ⅳ. Cov Lus Qhia Luv Luv
Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis xuab zeb thiab kev lag luam tsim khoom txav mus rau qhov tseeb dua thiab kev tiv thaiv ib puag ncig siab dua, cov ntaub ntawv xuab zeb ib txwm tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov txheej txheem siab. Silicon dub, ua cov khoom siv abrasive nrog lub zog siab, kev cuam tshuam qis, kev ntshiab siab thiab kev tiv thaiv ib puag ncig, tab tom dhau los ua cov khoom siv txhim kho tseem ceeb hauv kev lag luam xuab zeb. Txawm hais tias nyob rau hauv kev tsim khoom precision, optical matte, lossis hauv kev ua cov khoom siv hluav taws xob, cov khoom siv aerospace pretreatment thiab lwm yam teb, silicon dub tau pom tias muaj kev cia siab dav dav.
