Kev puas tsuaj ntawm cov khoom siv lim hlau nplaum rau kev tshem tawm yog 20 ~ 35% siab dua li ntawm cov khoom siv lim magnetite zoo tib yam.Koj tuaj yeem xa mus rau qhov kev vam meej hauv lwm qhov chaw.Ntawm lawv, kev tshawb fawb ntawm peb-txheej lim lim thiab kev txhawb nqa ntawm cov txiaj ntsig, lub txaj lim ntawm peb txheej lim lim, thiab RZG hom magnetite lim tau xaiv los ntawm cov pob zeb tsis tshua muaj siab ultra-siab metamorphic.Ib yam li qee cov qog nqaij hlav 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.Cov khoom siv lim nrog me me particle loj thiab lub ntiajteb txawj nqus loj yog muab faib rau hauv qis txheej.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.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 kuj tseem yuav sandblasted rau kev ntxuav saum npoo ua ntej pickling passivation.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 txheej txheem lim dej, qhov tshwj xeeb lub ntiajteb txawj nqus yog siab thiab cov ntsiab lus ntawm cov hlau yog siab, yog li muaj plua plav tsawg dua thaum lub sij hawm sandblasting txheej txheem, thiab cov khoom siv lim ntawm qhov nruab nrab particle loj thiab lub ntiajteb txawj nqus tshwj xeeb raug faib rau hauv nruab nrab.Cov uas muaj FeTiO3 (tseem qhia raws li FeOTiO2) tuaj yeem txo tus nqi..

Peb lim xov xwm los siv rau kev tshem tawm

Kev ua haujlwm ib puag ncig yuav zoo dua li quartz xuab zeb.Yuav xaiv cov lim xov xwm li cas?Cov xov xwm lim dej uas muaj qhov loj me me thiab lub ntiajteb txawj nqus me me tau muab faib rau hauv cov txheej txheem sab saud, lossis kom ua tiav cov txheej txheem txheej txheem los yog qhov chaw muaj qhov chaw frosted kom txo qhov kev xav, thiab tshem tawm tag nrho cov oxide nplai, xeb, soluble ntsev thiab lwm yam av.Lub sijhawm no, 11126 thiab iso tau txheeb xyuas thiab hloov kho los ntawm kev sim, thiab qhov crushing tus nqi qis qis thaum lub sijhawm sandblasting txheej txheem, thiab tib lub sijhawm, lub voj voog pom 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.

Cov nyhuv ntawm peb hom lim cov ntaub ntawv siv rau kev tshem tawm 2

Lub tshuab lim dej thaum lub sij hawm kev ntxuav tu yog hloov kho tas li.Cov txheej txheem kev cai xws li 11127 thiab PSPC tuaj yeem yooj yim ua rau cov txheej txheem sib xyaw ntawm cov khoom siv lim dej thiab cov ntaub pua chaw pw thaum lub sijhawm rov qab ntxuav.Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog xaiv cov khoom siv lim high-density magnetite uas huv si, tsis muaj tshuaj lom neeg thiab tsis muaj teeb meem RZG garnet plua plav-dawb sandblasting abrasive.Cov khoom xyaw tsis zoo xws li cov hlau hnyav muaj txiaj ntsig zoo heev thiab maj mam ua me me.

Lub txaj lim ntawm lub lim yog tsim los ntawm peb txheej ntawm cov khoom siv lim.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 tshwj xeeb ntawm cov khoom siv lim, nws ua tiav cov txheej txheej adhesion muaj zog thiab ntev txheej txheej kev pab cuam lub neej.High hardness, siab ceev, zoo toughness, ntse ces kaum thiab ntse npoo.Lub sandblasted nto tsis muaj embeddings, yog li ntawd lub lim txaj cov av interception muaj peev xwm yuav siv tau tag nrho, uas yog, qhov nruab nrab ntawm peb lim xov xwm Qhov particle loj yog los ntawm sab saum toj mus rau hauv qab.
