Lub tshuab lim dej niaj hnubkos cov tshuab ntxuavyog niaj hnub hloov tshiab.Cov txheej txheem kev cai xws li 11127 thiab PSPC tuaj yeem yooj yim ua rau cov txheej txheem sib xyaw ntawm cov ntaub ntawv lim thiab cov ntaub pua chaw pw thaum lub sijhawm rov qab ntxuav.Tsis txhob siv mechanically siv lawv.Cov kab kos yog ntxuav nrog ntshiab, tsis muaj tshuaj lom neeg thiab tsis muaj teeb meem RZG garnet plua plav-dawb sandblasting abrasive, thiab nws yog siv thiab rov siv dua.Qhov kev xaiv ntawm cov khoom siv lim high-density magnetite li cov khib nyiab yog qhov tseem ceeb tshwj xeeb.Nws tsis muaj cov silicon dawb, cov khoom tsis zoo xws li cov hlau hnyav muaj kev txiav zoo heev thiab maj mam ua me me.Nws yog qib siab, ntshiab ntuj tsis yog xim hlau sandblasting abrasive.

Tsis tas li ntawd, nws yuav tsum tau ua raws li cov xwm txheej hauv zos, thiab cov hlau tsis muaj steel yuav tsum tau sandblasted ua ntej pickling passivation rau qhov chaw tu.Cov plua plav cov ntsiab lus tsawg heev, thiab cov roj stains uas muaj nyob rau ntawm qhov chaw raug tshem tawm.2g / cm3, ntse ces kaum, thiab dej zoo.Thaum tsim cov lim txaj specifications, qhov tshwj xeeb lub ntiajteb txawj nqus yog siab thiab cov ntsiab lus hlau yog siab, yog li muaj cov plua plav tsawg dua thaum lub sij hawm sandblasting txheej txheem, thiab cov khoom siv lim nrog cov ntsiab lus ntawm qhov nruab nrab particle loj yog faib rau hauv nruab nrab.Cov uas muaj FeTiO3 (tseem qhia raws li FeOTiO2) tuaj yeem txo tus nqi., Qhov chaw ua haujlwm yuav zoo dua li quartz xuab zeb.Kev puas tsuaj ntawm RZG magnetite lim cov khoom siv rau kev tshem tawm yog 20 ~ 35% siab dua li cov khoom siv hlau nplaum zoo tib yam.Muaj peev xwm xa mus rau qhov kev vam meej hauv lwm qhov chaw, suav nrog kev tshawb fawb ntawm peb txheej lim xov xwm thiab kev txhawb nqa ntawm cov txiaj ntsig, lub txaj lim dej ntawm peb txheej lim xov xwm, thiab RZG hom magnetite lim xov xwm raug xaiv los ntawm qhov tsis tshua muaj ultra- siab siab metamorphic pob zeb.

1. Raws li qee yam mob qog noj ntshav tshwm sim los ntawm cov hlau hnyav hnyav, lawv tau txais kev saib xyuas dav dav los ntawm kev kho dej hauv tsev thiab txawv teb chaws.Yog tias siv cov khib nyiab me me los yog tsis tsim nyog siv, kev hloov pauv mus rau qhov chaw dej kom muaj turbidity siab lossis loj turbidity fluctuations yuav ntxiv dag zog.Nws tuaj yeem tshem tawm impurities xws li xeb thiab oxide nplai.

2. Cov khoom siv lim nrog me me particle loj thiab lub ntiajteb txawj nqus loj yog muab faib rau hauv txheej qis.Qhov tso cai lim ceev rau kev tshem tawm kab yog siab, thiab qhov roughness ntawm qhov chaw ua tau raws li qee qhov yuav tsum tau ua.Qhov loj me me yog qhov tsim nyog, cov hmoov av me me, cov ntsiab lus ntawm cov ntsev soluble (chloride) thiab cov hluav taws xob conductivity tsawg heev, thiab cov xuab zeb blasting cheeb tsam ib chav tsev yog loj thiab chav tsev.Cov xuab zeb sab saud yog me me, uas ua tau raws li cov kev cai nruj tshaj plaws ntawm kev lag luam thiab kev ua tub rog.

3. Yuav ua li cas xaiv thiab muab cov khoom lim?Cov khoom siv lim nrog qhov loj me me thiab lub ntiajteb txawj nqus me me yog muab faib rau hauv cov txheej txheem sab saud, lossis kom ua tiav lub hom phiaj thev naus laus zis lossis qhov chaw muaj qhov frosted saum npoo kom txo qhov kev xav, thiab tshem tawm tag nrho cov oxide nplai, xeb, soluble ntsev thiab lwm yam av.

4. Lub sijhawm no, 11126 thiab iso raug txheeb xyuas thiab hloov kho los ntawm kev sim, thiab tus nqi tawg yog tsawg thaum lub sijhawm ua cov txheej txheem sandblasting, thiab tib lub sijhawm, lub voj voog lim tau ntev.Nyob ntawm daim ntawv thov, nws tuaj yeem rov ua dua 5-10 zaug.Cov lim no muaj peev xwm cuam tshuam loj av, 5-8.Yog li lub voj voog lim tau ntev,

Qhov tseeb, vim yog cov khoom siv lim dej tsis huv, cov dej ntws tsis zoo, thiab qhov sib txawv ntawm qhov loj me thiab lub ntiajteb txawj nqus ntawm cov khoom siv lim, muaj zog txheej adhesion thiab ntev txheej txheej kev pab cuam lub neej yog tiav.Nrog kev nyuaj siab, siab ntom, kev nruj me me, cov khoom siv ntse nyob rau saum npoo av tom qab lub txaj kev sib cuam tshuam tau muaj peev xwm tau txais kev siv zog.Qhov nruab nrab particle loj ntawm cov khoom yog tsim los ntawm peb txheej ntawm cov khoom lim.
