Covcim kab tshem tawmmagnetite lim khoom ua rau kom hnav tsis kam los ntawm 20 ~ 35% piv nrog cov khoom siv lim magnetite zoo tib yam.Muaj peev xwm xa mus rau qhov kev vam meej hauv kev lag luam, suav nrog kev tshawb fawb thiab kev txhawb nqa ntawm peb-txheej lim xov xwm lim, lim txaj ntawm peb-txheej lim xov xwm lim, magnetite lim xov xwm xaiv los ntawm cov pob zeb tsis tshua muaj siab ultra-siab metamorphic, thiab tshuaj lom tej yam mob qog noj ntshav los ntawm cov hlau hnyav tau txais kev saib xyuas thoob plaws hauv zej zog kev kho dej hauv tsev thiab txawv teb chaws.Yog tias siv cov khib nyiab me me los yog tsis tsim nyog tau siv, kev hloov pauv mus rau qhov siab turbidity lossis turbidity fluctuations rau hauv cov dej yog ntxiv dag zog.Cov khib nyiab xws li xeb thiab nplai tuaj yeem raug tshem tawm.Cov khoom siv lim nrog me me particle loj thiab lub ntiajteb txawj nqus loj yog muab faib rau hauv qis txheej.Kev tshem tawm cov kab tso cai tso cai rau kev pom ceev ceev, thiab ua rau lub ntsej muag roughness ua tau raws li qee qhov kev xav tau, tsim nyog particle loj tis, tsawg plua plav, soluble ntsev (chloride) cov ntsiab lus thiab tsis tshua muaj conductivity, loj blasting cheeb tsam thiab chav tsev ib lub sij hawm nws muaj tsawg xuab zeb noj. thiab ua tau raws li cov kev cai nruj tshaj plaws ntawm kev lag luam thiab kev ua tub rog.

1. Nws yog qib siab, ntshiab ntuj tsis yog hlau sandblasting abrasive.Tsis tas li ntawd, raws li cov xwm txheej hauv cheeb tsam, cov hlau tsis muaj steel kuj tseem yuav sandblasted rau kev ntxuav saum npoo ua ntej pickling thiab passivation.Cov plua plav cov ntsiab lus tsis tshua muaj siab, thiab cov roj stains uas muaj nyob rau ntawm qhov chaw raug tshem tawm, 2g / cm3, cov ces kaum yog ntse, thiab cov dej zoo.Thaum tsim cov txheej txheem lim dej, qhov tshwj xeeb lub ntiajteb txawj nqus thiab cov ntsiab lus hlau yog siab, yog li muaj cov plua plav tsawg dua hauv cov txheej txheem blasting, thiab cov khoom siv lim dej uas muaj qhov tshwj xeeb hauv qhov nruab nrab particle loj yog faib rau hauv nruab nrab, thiab muaj FeTiO3 ( kuj qhia raws li FeOTiO2), uas tuaj yeem txo cov nqi.

2. Qhov chaw ua haujlwm yuav zoo dua li quartz xuab zeb.Yuav ua li cas xaiv cov khoom lim Yuav ua li cas xaiv cov khoom siv lim nrog qhov loj me me thiab lub ntiajteb txawj nqus me me yog muab faib rau hauv txheej txheej sab saud, lossis ua tiav lub hom phiaj thev naus laus zis lossis tsim cov matte nto kom txo qhov kev xav, thiab tshem tawm tag nrho cov nplai, xeb. , soluble ntsev thiab lwm yam av.Tom qab kev sim thiab kev txheeb xyuas thiab kev hloov kho, tus nqi crushing yog tsawg thaum lub sij hawm blasting txheej txheem, thiab tib lub sij hawm, 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 sij hawm filtration yog ntev,

3. Lub tshuab lim dej thaum lub sij hawm niaj hnub kev ntxuav yog tas li hloov kho cov lus qhia tshwj xeeb, nws yooj yim los ua cov khoom lim thiab cov khoom siv padding sib xyaw hauv cov txheej txheem rov qab, thiab nws yog txwv tsis pub txav mus los nyuaj.Cov kab kos npe ntxuav cov ntshiab, tsis muaj tshuaj lom neeg thiab tsis muaj kev phom sij RZG garnet plua plav-dawb blasting abrasive, thiab nws yog siv thiab rov siv dua.Kev xaiv ntawm high-density lim magnetite raws li lub ncoo yog qhov tseem ceeb tshwj xeeb.Nws tsis muaj silicon dawb, Hnyav hlau thiab lwm yam khoom muaj teeb meem muaj kev txiav zoo heev thiab maj mam ua me me.

4. Lub txaj lim ntawm lub lim muaj peb txheej ntawm cov khoom siv lim.Qhov tseeb, vim yog cov khoom siv lim dej tsis huv, cov dej ntws tsis zoo, cov khoom siv lim sib txawv me me thiab lub ntiajteb txawj nqus, thiab lwm yam, muaj zog txheej adhesion thiab ntev txheej txheej kev pab cuam lub neej.High hardness, siab ceev, zoo toughness, ntse ces kaum thiab ntse ntug toughness, lub sandblasted nto tsis muaj inserts, thiaj li hais tias lub lim txaj cov av interception muaj peev xwm ua tau tag nrho exerted, uas yog, qhov nruab nrab ntawm peb lim ntaub ntawv particle loj yog los ntawm sab saum toj mus rau hauv qab.
