Brown Corundum Thiab Garnet Qhov txawv
Brown corundum abrasives thiab garnet abrasives yog dav siv abrasives, cov tshuaj tseem ceeb ntawm cov xim av corundum yog Al2O3, nws cov ntsiab lus yog 95.00%-97.00%, thiab muaj me me. ntawm Fe, Si, Ti thiab lwm yam oxides, feem ntau yog xim av thiab dub. Cov tshuaj tseem ceeb ntawm garnet suav nrog SiO2 (36-40%), Al2O3(20-24%), FeO({11}}%), nrog rau Fe2O3, TiO2, MgO, CaO thiab lwm yam khoom siv. , xim yog muab faib ua xim av, dub, liab, ntsuab thiab lwm yam.
Vim qhov zoo sib xws ntawm cov xim thiab tshuaj lom neeg muaj pes tsawg leeg, hauv kev tsim cov log sib tsoo, peb yuav xav tias npau taws thaum cov xim av corundum abrasive sib xyaw nrog cov xuab zeb thib ob, cov xuab zeb tertiary thiab txawm tias cov tawv nqaij ua kom sov, thiab qhov xwm txheej ntawm garnet raws li cov xuab zeb yog qhov npau taws heev. , uas tsis tau hnov txog hauv kev lag luam. Tsav los ntawm kev txaus siab, qee cov tuam txhab tsis paub cai nrhiav cov txiaj ntsig ntawm kev siv lub koob npe nrov.
Hais txog keeb kwm, xim av corundum yog ua los ntawm bauxite, hlau chips, coke (anthracite) los ntawm melting thiab txo nyob rau hauv hluav taws xob arc rauv; Garnet yog lub ntuj tsis yog hlau ore.
Hais txog lub cev thiab tshuaj lom neeg, xim av corundum Al2O3 cov ntsiab lus yog siab, hardness yog li 9.0, thiab hluav taws kub kuj zoo, thaum garnet Al2O3 cov ntsiab lus yog tsawg, hardness yog 7.5-8. {8}}, thiab corrosion kuj zoo. Hauv daim ntawv thov sandblasting, garnet abrasive tuaj yeem tsis tsuas yog ua lub luag haujlwm ntawm kev tshem tawm, tab sis kuj tseem tiv thaiv cov khoom siv sandblasting los ntawm khawb, thiab nws cov kev ua tau zoo dua li xim av corundum; Txawm li cas los xij, hauv kev tsim cov cuab yeej abrasive, hnav tsis kam ntawm corundum xim av yog pom tseeb zoo dua li ntawm garnet.
Nyob rau hauv cov nqe lus ntawm tus nqi, garnet abrasives yog ua los ntawm ntuj raw pob zeb tom qab crushing thiab ua, thiab tus nqi qis dua; Brown corundum yog bauxite, coke, hlau filings, thiab lwm yam., raws li ib tug tej yam ratio ntawm tov melting, cov nqi ntau lawm yog ho siab tshaj garnet, lub lag luam tus nqi kuj siab.
Qib qis VS qib siab
Bauxite yog cov khoom siv tseem ceeb rau smelting xim av corundum, cov ntsiab lus tseem ceeb rau nws cov tshuaj muaj pes tsawg leeg yog alumina thiab silicon oxide cov ntsiab lus, thiab cov neeg siv khoom muaj lwm yam kev xav tau rau lub cev ntom ntom, calcium oxide, magnesium oxide cov ntsiab lus thiab lwm yam.
Yav dhau los, nyob rau hauv ib txwm muaj xwm txheej, xim av corundum smelting lag luam xav kom cov ntsiab lus tshuaj ntawm alumina hauv bauxite tsis tsawg dua 85 (silicon cov ntsiab lus hauv qab 4.0). Tam sim no, nws yog qhov nyuaj rau yuav qhov tiag 85 ore ntawm kev ua lag luam, feem ntau yog 80 txog 83 ore (silicon cov ntsiab lus siab dua 7.0). Ua ntej, nrog kev ua haujlwm tsis tu ncua, cov khoom siv bauxite zoo tau nce zuj zus; Qhov thib ob yog vim li cas qhov kev kub ntxhov ib puag ncig tau ua rau kev tsim cov ore mining, thiab feem ntau bauxite kilns raug yuam kom kaw vim yog cov qauv kev tiv thaiv ib puag ncig. Qhov no tau ua rau cov khoom lag luam nruj ntawm bauxite nyob rau hauv kev ua lag luam, feem ntau cov tuam txhab bauxite tau shovelled, thiab cov txhuas-silicon piv kuj poob qis, ua rau corundum smelting kev khiav hauj lwm, lub sij hawm ntev, nce zog noj, thiab ib tug ncaj nce nyob rau hauv cov nqi ntau lawm.
Qhov tseeb, tsis muaj qhov hu ua qhov tseeb lossis cuav bauxite, qhov tseem ceeb nyob hauv cov ntsiab lus tshuaj lom neeg, qib, txawm tias tsis zoo.
Cov saum toj no tsuas yog ib daim ntawv teev cov neeg mob, hauv kev lag luam abrasives, abrasives thiab lwm yam khoom siv raw khoom ntawm kev dag ntxias thiab kev deev luag poj luag txiv yog kev nyuaj siab (txawm tias cov khoom lag luam abrasive tsim cov lag luam, cov chaw soj ntsuam zoo thiab cov khoom lag luam raw khoom sib cuam tshuam nrog cov khoom cuav cuav), thiab kev ntshaw ib feem ntawm cov khoom abrasive thiab lwm cov chaw tsim khoom lag luam downstream tau pib xav kom cov neeg muag khoom siv raw khoom mus rau kev dag ntxias, kev deev luag poj luag txiv, txhawm rau txo cov nqi tsim khoom, Sib ntaus sib tua nqi. Hauv kev lag luam abrasive abrasives, kev ruaj ntseg ntawm cov khoom yog dav thuam, uas tsis cuam tshuam rau kev dag ntxias thiab kev deev luag poj luag txiv.
