Cov txiaj ntsig ntawm Aluminium Oxide
Cov ntsiab lus hlau tsawg
Aluminium oxide muaj cov ntsiab lus hlau tsawg, uas tiv thaiv cov abrasive los ntawm kev tawm xeb ntawm ib feem ntawm qhov chaw. Cov xeb xeb ua rau muaj teeb meem hauv cov txheej txheem yav tom ntej, xws li pitting lossis nce nqi kho, ua rau txhuas oxide muaj kev nyab xeeb xaiv rau stripping thiab xov.
Kev rov ua dua tshiab
Thaum siv aluminium oxide nyob rau hauv cov txheej txheem blasting, nws yog ruaj txaus los tiv thaiv ntau dhau. Reclaiming cov ntaub ntawv no rau ntau yam kev siv tso cai rau koj mus ua kom koj cov peev txheej thiab ua rau aluminium oxide zoo heev. Aluminium oxide kuj tseem tuaj yeem siv rov qab rau qee lub tuam txhab rau kev rov ua dua tshiab, uas txo cov nqi pov tseg thiab kev cuam tshuam ib puag ncig.
Siab toughness
Aluminium oxide muaj zog ntau dua li lwm yam abrasives, tshwj xeeb tshaj yog xim av ntau yam. Qhov no toughness ua rau tsawg particle shatter thiab ua rau cov plua plav qis dua. Thaum cov cuab yeej tiv thaiv tus kheej (PPE) feem ntau xav tau rau kev tawg blasting, aluminium oxide cov hmoov av tsawg ua rau nws xaiv tau.
Qhov ntau thiab tsawg grit
Cov xov xwm blasting no muab qhov project versatility nrog ntau qhov sib txawv grit. Xaiv cov grits loj dua los tsim kom muaj qhov sib xws. Finer grits yog haum rau cov ncauj lus kom ntxaws nto ua hauj lwm, xws li tshem tawm irregularities thiab ncav cuag rau hauv grooves thiab tawg. Koj tuaj yeem kho koj qhov chaw tiav nrog ntau pua ntawm grit loj thiab grain zoo sib xyaw ua ke.
Hom ntawm Aluminium Oxide
Calcium aluminate (CaAlO3)
Calcium aluminate (CaAlO3) yog ib qho aluminate ceramic siv hauv cov cement refractory thiab cov duab, nrog rau cov khoom siv hluavtaws ntxiv rau kev ua haujlwm metallurgy.
Sapphire
Sapphire yog lub siab dawb huv thiab siab ceev, ib leeg-crystalline daim ntawv ntawm txhuas oxide uas yuav muaj chromia, titania, yttria, los yog lwm yam dopants. Sapphire feem ntau yog pob tshab lossis translucent.
Zirconia-toughened alumina (ZTA)
Zirconia-toughened alumina (ZTA) thiab lwm yam zirconia-alumina ceramics feem ntau siv rau hauv daim ntaub ntawv siv los ua ib qho kev daws teeb meem ntawm alumina thiab zirconia. ZTA muab cov pob txha tawg ntau dua alumina ntawm tus nqi qis dua piv rau cov ntshiab lossis siab zirconia ceramics.
Kev siv ntawm Aluminium Oxide
Kev lag luam kho mob
Cov khoom siv tshuaj lom neeg ntawm aluminium oxide, nrog rau nws cov hardness thiab bio-inertness ua rau nws cov khoom tsim nyog rau ntau yam kev siv kho mob, suav nrog kev cog qoob loo bionic, cov ntaub so ntswg ntxiv, prostheses, hip hloov bearings, thiab lwm yam.
Cov cuab yeej tiv thaiv
Lub teeb yuag zoo thiab lub zog ntawm aluminium oxide ua rau nws yog ib qho kev xaiv zoo rau kev txhim kho lub cev thiab lub tsheb armor, nrog rau tsim cov hluavtaws-sapphire mos txwv ballistics thiab qhov rais.
Hluav taws xob kev lag luam
Cov ntsiab lus kub kub thiab melting ntawm aluminium oxide ua rau qhov sib xyaw no yog qhov kev xaiv zoo rau kev tsim cov hluav taws kub kub rwb thaiv tsev, nrog rau cov hluav taws xob insulators. Alumina kuj tau siv dav hauv kev lag luam microchip.
Lub pov haum kev lag luam
Aluminium oxide yog siv nyob rau hauv tus txheej txheem ntawm tsim sapphires thiab rubies. Nyob rau hauv nws daim ntawv crystalline, los yog corundum, alumina yog lub hauv paus rau kev tsim ntawm ob lub pov haum muaj nuj nqis.
Daim ntawv thov kev lag luam
Vim tias txhuas oxide yog cov tshuaj inert, nws yog qhov zoo tshaj plaws muab tub lim rau cib, plastics, thiab hnyav clayware. Nws kuj yog feem ntau siv los ua cov khoom sib tsoo ntawm cov ntawv xuab zeb, thiab kev hloov pauv kev lag luam rau cov pob zeb diamond.
Cov tshuaj tiv thaiv nrog sodium hydroxide
Aluminium oxide reacts nrog sodium hydroxide los tsim sodium aluminate thiab dej. Cov tshuaj tiv thaiv no tshwm sim ntawm qhov kub ntawm 900-1100 degree . Cov ntsev thiab dej tau txais nyob rau hauv cov tshuaj tiv thaiv no uas aluminium oxide ua raws li cov kua qaub.
Cov tshuaj tiv thaiv nrog sulfuric acid
Cov hlau oxides feem ntau yog qhov yooj yim tab sis txhuas oxide yog amphoteric oxide.Li no nws ua ob qho tib si acid thiab puag. Hauv qhov no, nws ua raws li lub hauv paus.
Cov tshuaj tiv thaiv nrog hydrochloric acid
Aluminium oxide muaj oxide ions, thiab yog li reacts nrog acids tib yam li sodium los yog magnesium oxides ua. Aluminium oxide reacts nrog kub dilute hydrochloric acid muab txhuas chloride tov.
Yuav ua li cas xaiv Aluminium Oxide
Xim
Aluminium oxide tuaj nyob rau hauv peb xim - dawb, liab thiab xim av - thiab txhua xim muaj ib tug txheej ntawm zoo uas zoo rau tej daim ntawv thov dua lwm yam. Dawb thiab paj yeeb ua haujlwm zoo tshaj plaws rau kev tsim kom zoo nkauj. Dawb ua haujlwm zoo tshaj plaws rau lacquers thiab ntoo rau nws qhov kev ua tau zoo thiab qis qis dua. Paj yeeb yog qhov zoo tagnrho rau kev sib tsoo, sib tsoo thiab cov ntoo mos.Brown muaj cov nplej muaj zog uas yuav siv sij hawm ntev dua kom deteriorate dua li cov paj liab thiab dawb. Qhov kev ua haujlwm siab dua no ua rau nws zoo dua rau cov khoom siv tawv.
Grit Loj
Thaum cov xim txhuas oxide cuam tshuam rau lub peev xwm abrasive, koj kuj tseem xav xav txog qhov loj me. Qhov loj me me me me yuav ua tau zoo dua rau kev ncav cuag grooves, tawg thiab nto irregularities. Cov grits loj dua yog qhov zoo dua rau qhov chaw zoo ib yam lossis tsawg dua qhov chaw ua haujlwm.
Synthesis ntawm Aluminium Oxide
Ua ntej, bauxite ore, thawj qhov chaw ntawm txhuas, yog mined thiab tom qab ntawd crushed thiab hauv av mus rau ib tug zoo hmoov los pab txhawb nqa aluminium oxide extraction. Cov bauxite yog tom qab ntawd raug rau kev zom zaub mov, cov txheej txheem kev kub ntxhov uas muaj cov kua dej kub ntawm sodium hydroxide (NaOH), uas yaj cov txhuas oxide thaum tawm hauv cov impurities qab. Tom qab kev zom zaub mov, ib qho kev qhia meej thiab kev sib cais cov txheej txheem tshem tawm cov khoom impurities, uas ua rau muaj cov kua ntshiab sodium aluminate. Los nag tshwm sim los ntawm kev txo cov tshuaj pH los ntawm carbon dioxide (CO2) ntxiv, ua rau nag lossis daus ntawm aluminium hydroxide. Tom qab filtration, lub precipitated aluminium hydroxide undergoes calcination ntawm kub kub kom yield alumina nyob rau hauv daim ntawv ntawm ib tug nplua dawb hmoov. Ntxiv cov txheej txheem refining tuaj yeem ua haujlwm kom ua tiav qhov kev xav tau purity rau cov ntawv thov tshwj xeeb. Cov khoom alumina kawg yog khaws cia, thauj, thiab siv ntau yam kev lag luam. Nws ua haujlwm tseem ceeb rau kev tsim cov khoom siv txhuas, qhov uas nws txo qis electrolytic hauv Hall-Héroult txheej txheem los tsim cov hlau txhuas. Kev txhawj xeeb txog ib puag ncig muaj feem cuam tshuam rau cov khoom pov tseg thaum lub sij hawm tsim cov alumina, xws li cov av nkos liab, hais txog qhov tseem ceeb ntawm kev tswj cov khib nyiab kom raug thiab cov kev coj ua kom ruaj khov.
Kev Tiv Thaiv Kev Nyab Xeeb Ntawm Aluminium Oxide
Cov hmoov av zoo los yog hmoov ntawm txhuas oxide tuaj yeem tsim teeb meem yog tias nqus tau. Kev raug mob ntev heev ntawm cov pa hauv cov pa txhuas oxide tuaj yeem ua rau ua pa ua pa, mob ntsws, thiab muaj peev xwm ua rau muaj kev txhawj xeeb mus ntev. Kev ua pa txaus thiab kev siv cov kev tiv thaiv ua pa tsim nyog yog qhov tseem ceeb thaum ua haujlwm nrog cov ntaub ntawv zoo ntawm aluminium oxide, xws li hauv kev lag luam lossis kev siv abrasive.
Kev sib cuag nrog daim tawv nqaij lossis qhov muag yuav ua rau khaus. Nws raug nquahu kom hnav khaub ncaws tiv thaiv, hnab looj tes, thiab kev tiv thaiv qhov muag thaum tuav cov txhuas oxide, tshwj xeeb tshaj yog tias muaj peev xwm ntawm daim tawv nqaij lossis qhov muag.
Thaum txhuas oxide feem ntau lees paub tias muaj kev nyab xeeb thaum noj cov khoom me me (nws yog siv los ua cov tshuaj tiv thaiv kab mob hauv cov khoom noj), nqos cov khoom siv txhuas ntau tuaj yeem ua rau muaj teeb meem kev noj qab haus huv. Kev noj tshuaj ntau dhau ntawm txhuas tau txuas rau qee yam kev txhawj xeeb txog kev noj qab haus huv, suav nrog kev muaj peev xwm neurotoxicity thiab pob txha.
Aluminium oxide tsis suav tias yog ib puag ncig muaj kev phom sij, tab sis zoo li lwm yam khoom siv hauv kev lag luam, nws cov khoom pov tseg yuav tsum tau tswj kom zoo kom txo tau qhov cuam tshuam rau ib puag ncig.
