Puas yog kos npe tshem tawm cov khoom siv lim dej uas tau xaiv los cuam tshuam?
Sijhawm: 10-27-2020
Covcov khoom siv tshem tawm txoj kev kos nperaug xaiv tsis raug vim yog kev xaiv tsis raug ntawm peb-txheej lim txaj gradation uas cuam tshuam rau cov khoom siv lim dej xaiv.FeTiO3 ua rau cov kua qaub thiab alkali tsis kam ntawm RZG hom magnetite lim cov ntaub ntawv siab dua li cov hlau nplaum zoo tib yam.Txawm li cas los xij, hom lim no, RZG tsis muaj plua plav-dawb garnet xuab zeb ua tiav raws li cov qauv zoo tshaj plaws, muaj kev daws teeb meem ceev ceev, thiab vim tias qhov qis tshaj ntawm cov khoom lim dej muaj qhov me me me me, nws muaj peev xwm tiv thaiv kev ncua. khoom los ntawm kev nkag mus.Lub cim yog ntxuav.Ordinary steel feem ntau yuav dhau los ntawm cov txheej txheem ntawm sandblasting thiab xeb tshem tawm ua ntej siv.Qhov ntom ntom 4. Qhov saum npoo roughness tuaj yeem ncav cuag 30-80 microns.Qhov tseeb, kev ntxuav yog siv los ua cov plua plav-dawb sandblasting abrasive.Vim yog lub ntiajteb txawj nqus tshwj xeeb ntawm garnet, nws feem ntau yog tsim los ntawm anthracite quartz xuab zeb thiab magnetite (los yog garnet).Feem ntau, RZG plua plav-dawb garnet sandblasting abrasive (natural emery) tuaj yeem siv.Tus nqi ntawm sandblasting yog tsawg.Ntxiv txo tus neeg siv cov nqi siv.
1. Ua tsaug rau qhov zoo heev toughness thiab tsis tshua muaj brittleness ntawm RZG garnet sandblasting abrasive, txheej sib tov yuav tshwm sim ntawm qhov chaw tom qab ntxuav nrog rov qab kos kab ntxuav.Cov txiaj ntsig kev lag luam thiab kev lag luam coj los ntawm kev tshem tawm cov cim kab yog qhov tseem ceeb, thiab nws tau hloov cov khoom qub hlau ballast (tooj liab ore), dej xuab zeb, thiab quartz xuab zeb.Kev ntxuav kom zoo ua rau muaj kev hnav tsis kam ntawm cov khoom siv hlau nplaum, ntxiv rau RZG plua plav-dawb garnet hardness 7. RZG plua plav-dawb garnet yog xaiv los ntawm cov khoom zoo hlau-aluminium garnet pob zeb ore, plua plav-dawb garnet sandblasting Lub abrasive tsis tsuas muaj Cov yam ntxwv ntawm cov khoom zoo thiab tus nqi qis, tsis muaj qhov cuam tshuam tsis zoo thiab cov pits, RZG tsis muaj plua plav garnet xuab zeb tuaj yeem nkag mus tob rau hauv qhov thiab qhov tsis sib xws rau kev ntxuav, tab sis kuj muaj cov khoom xyaw Al2O3 zoo.Tom qab ntau qhov kev ntxuav hauv cov txheej txheem tsim khoom, Nws yog tsis yooj yim sua kom ua tiav qhov tsis sib xyaw tom qab ua raws li iso backwash.
2. Lub tshuab ntxhua khaub ncaws kuj tseem tuaj yeem zam cov kab mob silicosis los ntawm cov silicon dawb thiab yooj yim tau txais qib siab tshaj sandblasting qib ntawm Sa3.Cov cuab yeej pom kev ntawm niaj hnub kos npe tu yog hloov kho tas li.Ntawm lawv, kev tshawb fawb ntawm peb-txheej lim xov xwm thiab kev txhawb nqa ntawm nws cov txiaj ntsig tau coj cov txiaj ntsig zoo tshaj plaws thiab kev lag luam rau kev tsim khoom.Yog li ntawd, nws tau siv dav los ntawm kev kho dej hauv tsev thiab txawv teb chaws.Ua tib zoo mloog.Tab sis rau hom lim no, yuav ua li cas xaiv cov khoom lim thiab yuav muab nws li cas?Raws li lub npe implies, lub txaj lim ntawm peb txheej lim yog tsim los ntawm peb txheej ntawm cov khoom lim.Cov lim dej no muaj lub peev xwm loj hauv av, muaj peev xwm tiv thaiv tau cov khib nyiab los ntawm kev nkag mus, kev lim dej siab, dej zoo, thiab kev lim dej ntev.Lub txaj lim ntawm peb txheej lim feem ntau yog tsim los ntawm anthracite, quartz xuab zeb thiab magnetite (los yog garnet).
3. Cov khoom siv lim dej uas muaj qhov loj me me thiab lub ntiajteb txawj nqus me me yog faib rau hauv txheej sab saud, cov khoom siv lim nrog cov khoom siv nruab nrab thiab qhov tshwj xeeb ntawm lub ntiajteb txawj nqus yog faib rau hauv nruab nrab, thiab cov khoom siv lim nrog me me particle loj thiab lub ntiajteb txawj nqus loj yog faib nyob rau hauv qis txheej.Ntawd yog, qhov nruab nrab particle loj ntawm peb cov ntaub ntawv lim maj mam txo qis los ntawm sab saum toj mus rau hauv qab.Nyob rau hauv txoj kev no, lub txaj lim cov dej phwj tuaj yeem siv tau tag nrho, yog li lub voj voog lim tau ntev, thiab vim tias qhov qis tshaj ntawm cov khoom lim dej muaj qhov me me me, nws yog qhov hloov tau rau siab turbidity lossis loj turbidity fluctuations.Thaum tsim cov kev qhia tshwj xeeb ntawm lub txaj lim, koj tuaj yeem xa mus rau qhov kev vam meej hauv lwm qhov chaw.Tsis tas li ntawd, nws yuav tsum tau txheeb xyuas thiab hloov kho los ntawm kev sim ua raws li cov xwm txheej hauv zos, thiab yuav tsum tsis txhob siv rau kev siv tshuab.Vim tias qhov kev xaiv tsis raug ntawm peb-txheej lim txaj gradation uas cuam tshuam rau cov khoom siv lim dej xaiv, txheej sib xyaw yuav tshwm sim tom qab cov khoom siv rov qab ntxuav cov cuab yeej ntws tawm.
4. 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 lim, nws tsis tuaj yeem ua tiav cov txheej txheem tsis sib xyaw tom qab rov qab ntxuav.Nyob rau lub sijhawm no, kev xaiv cov khoom siv lim high-density magnetite li cov khib nyiab yog qhov tseem ceeb.Yog tias cov khib nyiab nrog lub ntiajteb txawj nqus me me lossis tsis tsim nyog siv, nws yooj yim ua rau cov khoom siv lim thiab cov khib nyiab tuaj yeem tshwm sim thaum lub sijhawm rov qab ntxuav, thiab RZG hom hlau nplaum Cov hlau ore lim cov khoom raug xaiv los ntawm qhov tsis tshua muaj siab ultra-siab. metamorphic pob zeb, uas muaj qhov tshwj xeeb loj, cov ntsiab lus hlau siab, thiab tseem muaj cov txiaj ntsig Al2O3 Cheebtsam.Lub cim ntxuav zoo heev ua rau kev hnav tsis kam ntawm cov khoom siv lim magnetite.Covmarking tu tshuab chaw tsim tshuaj paus's Cov hnav tsis kam ntawm RZG magnetite lim xov xwm yog 20 ~ 35% siab dua li cov khoom siv hlau nplaum zoo tib yam.Nyob rau tib lub sijhawm, cov khoom muaj FeTiO3 (tseem qhia tias yog FeOTiO2) thiab FeTiO3 ua rau cov kua qaub thiab alkali tsis kam ntawm RZG hom magnetite lim cov khoom hnyav dua li cov hlau nplaum zoo tib yam.
