Dab tsi yog cov khoom loj alumina

High alumina npasYog sib tsoo media nrog cov ntsiab lus alumina ntawm ntau tshaj 90%, muaj cov pob alumina, uas tau muab faib ua cov lus alumina xws li 905, 99, thiab lwm yam raws li cov ntsiab lus alumina. Nws cov yam ntxwv suav nrog lub zog siab, siab tawv, hnav tsis kam, kub tsis kam, thiab corrosion tsis kam. Nws yog tsuas yog siv nyob rau hauv kev ua kom zoo ntawm cov ntaub ntawv nyuaj hauv kev lag luam xws li ceramics, iav, thiab tshuaj lom neeg engineering.
Cov chaw tsim hluav taws xob loj yog nyob hauv Shandong thiab Foshan, Guangeng, thiab cov kev tua hluav taws xob, thiab muaj ntau txoj kev sib raug zoo tuaj yeem txo qhov tiag tiag coj kev tiv thaiv tiag tiag. Hauv kev lag luam kev lag luam kev lag luam, ntxiv cov khoom loj Kev siv cov pob zeb loj hauv kev lag luam xws li Quartz tuaj yeem txhim kho qhov zoo ntawm silicon micro hmoov tau yooj yim ua rau cov khoom lag luam uas tsim tau yooj yim.
Cov kev sib nqus tshwj xeeb ntawm cov pob alumina siab feem ntau yog sab saud 3.60 (92% cov ntsiab lus), nrog mohs tawv ntawm qib 9, thiab yog tsim siv dov lossis iSostatic nias cov txheej txheem [2]. Nws cov cwj pwm tsis muaj maj mam hloov pauv kev sib tsoo hauv liaj teb xws li cov khoom siv refractory, ntim khoom siv hluav taws xob, thiab ntim hluav taws xob.
Khoom nta
High alumina npastau siv dav hauv qhov precision thiab sib sib zog nqus cov tuab thiab cov khoom siv nyuaj, cov khoom siv hluav taws xob ntau, kev ua haujlwm siab, thiab tsis muaj kuab paug.
Nqa lub pob alumina siab nrog cov ntsiab lus ntawm 92% raws li ib qho piv txwv, nws cov ntsiab lus tshwj xeeb) yuav tsum yog saum toj 91.5%, thiab cov ntsiab lus hlau yuav tsum tsawg. Nyob rau hauv tib cov ntaub ntawv raw, cov mis, thiab hluav taws kub thiab cov hmoov zoo tom qab sib tsoo, qhov ntau dua lub ntiajteb txawj nqus thiab hnav tsis kam. Cov kev sib nqus tshwj xeeb ntawm cov pob alumina siab yog feem ntau cuam tshuam los ntawm hmoov thiab kev tua hluav taws. Yam xws li underbooking, coarse hmoov, thiab ntxiv rau impurities tuaj yeem ua rau lub pob zeb tsis txaus ntawm pob zeb pob. Tsis muaj qhov qis dua lub ntiajteb txawj nqus Spherulites tsis yog hnav, tab sis cov kev sib tsoo tau yooj yim heev, yog tias muaj kev sib tsoo dhau los kuj tseem tuaj yeem ua tiav cov khoom lag luam siab dua.
Qhov tseem ceeb tshaj plaws ntawm lub pob zeb pob yog nws cov coj tsis kam. Qee lub tsev xeem ntawv tseem tuaj yeem ua cov kev xeem, thiab cov ntawv xeem no tuaj yeem qhia qhov zoo ntawm pob zeb pob zeb. Txawm li cas los xij, cov ntaub ntawv yog rau kev siv xwb vim tias ib puag ncig cov mob rau kev kuaj sim thiab tsim tau sib txawv. Firstly, kev ntsuam xyuas yog ua los ntawm cov dej sib tsoo, thaum muaj ntau cov tuam ntxhab siv cov kev sib tsoo qhuav; Thib ob, ntau zaus thaum sim, tsis muaj lwm cov ntaub ntawv raw ntxiv, tsuas yog kev sib txhuam yuav tsum tau ntxiv rau cov txheej txheem ntau lawm. Hauv kev siv cov txheej txheem tiag tiag, txhawm rau txhawm rau txhawm rau hnav ntawm pob zeb pob, nws yog ib qho tsim nyog los ua cov ntaub ntawv ntau ntxiv. Tom qab thawj zaug sib tov sib piv, los ntawm sau cov naj npawb ntawm cov pob zeb ntxiv, yog li los sib txuas qhov kev sib tsoo hauv cov pob zeb, thiab tseem yuav piv qhov zoo ntawm pob zeb pob zeb, thiab tseem muaj qhov zoo ntawm pob zeb pob zeb, thiab tseem muaj cov pob zeb zoo nkauj, thiab tseem sib txuas qhov zoo ntawm pob zeb pob zeb ntawm ntau cov khoom lag luam. Tej yam uas cuam tshuam rau kev hnav pob zeb pob muaj xws li tsis yog lub hardness thiab zoo ntawm lub pob zeb sib tsoo, tab sis cov kev sib tsoo ntawm pob zeb sib tsoo yog tsim nyog, thiab lub viscosity ntawm pub.
Qhov chaw ntau lawm ntau lawm ntawm cov khoom kub zoo nkauj heev hauv Suav teb yog Shandong thiab Foshan, Guangdong. Hom hauv Shandong suav nrog Zhongcas, Dongci, thiab lwm yam. Foshan muaj Wangao thiab Tegaote, ntawm Zhongcasote loj tshaj plaws thiab tawm. Qhov zoo ntawm nws cov microbeads tau raug lees paub los ntawm cov phooj ywg hauv tsev thiab txawv teb chaws thiab cov neeg siv khoom, thaum wangao cov khoom lag luam zoo yog qhov ruaj khov.
Cov tau txais daim ntawv thov
Feem ntau yog nyob rau hauv tej hub factories, siv pebbles (pob zeb ntuj) thiab 10%High alumina npas(Inch 35mm) kom zom cov av nkos nyias yuav ua rau lub sijhawm sib tsoo los ntawm 15% piv rau siv tsuas yog pebbles; Los ntawm kev siv nruab nrab aluminium npas thiab 30% cov pob zeb siab txhuas (lub sijhawm sib tsoo tuaj yeem raug txo los ntawm 30% piv rau kev siv nruab nrab aluminium npas. Suav nrog tus nqi hluav taws xob tau txais txiaj ntsig, tus nqi ntawm kev siv cov pob xim siab tuaj yeem yog "dim" hauv 2 xyoo. Raws li cov lus tshaj tawm los ntawm cov khoom lag luam ib tus neeg, pob zeb mills siv cov pob loj loj thiab cov alumina siab dua tshiab Cib hloov nruab nrab Alumina sib tsoo cov khoom sib tsoo ceramic rawing ceramic raw khoom. Qhov ploj ntawm pob zeb muaj tsawg dua ib -}} thib peb ntawm qhov nruab nrab ntawm nruab nrab cov pob, thiab lub sijhawm sib tsoo yog txo los ntawm 20%. Cov khoom lag luam zoo dua yog qhov ruaj khov dua, thiab cov khoom polumina muaj lub neej kev pabcuam ntev dua yam tsis muaj kev pab cuam ntau dua ntawm cov hnab pob, ua rau muaj cov nqi siab dua. Sib tsoo cov ntaub ntawv rawing nrog cov khoom loj uas tsis tuaj yeem tsuas yog txuag hluav taws xob cov nqi thiab nce ntau lawm, kev tiv thaiv kev tiv thaiv zoo rau cov khoom siv kho txhua yam.
Ntxiv rau kev lag luam ceramic, kev lag luam xws li Quartz thiab tshuaj lom neeg tau sim thiab siv cov pob alumina siab rau ntau lawm. Lub Hoobkas Quartz feem ntau yog siv rau kev tsim cov khoom silicon micro. Kev xyaum tau qhia tias siv cov pob alumina siab es tsis txhob sib tsoo hauv cov khoom sib tsoo thiab cov khoom lag luam zoo li dawb thiab hnav khaub ncaws. Ntxiv mus, vim hais tias qeeb qeeb poob piv rau quartz pob, cov nqi zog thiab cov nqi ntawm kev ntxiv cov spherulites tau txais kev cawmdim. Qhov teeb meem tseem ceeb tau ntsib thaum siv cov pob alumina siab yog vim lawv cov pob zeb ua kom yooj yim tuaj yeem ua rau cov pob zeb kom yooj yim thiab ua kom qhuav, ua rau muaj kev hnav zoo nkauj heev. Yog li ntawd, tsuas yog tus qauv ntawm polishing cov pob zeb ua ntej tawm hauv lub Hoobkas tuaj yeem siv los xaiv cov pob zeb nrog kev tawg lossis hnav, txhawm rau txo cov neeg siv khoom poob.
