Brown aluminium oxide tau dav siv nyob rau hauv ntau yam lag luam ua ob qho tib si abrasive thiab lim khoom. Raws li abrasive, nws yog lub npe hu ua "cov hniav ntawm kev lag luam" vim tias nws tus kheej zoo -sharpening zog thiab muaj zog sib tsoo zog. Nws tuaj yeem siv rau sandblasting, polishing, sib tsoo, cov ntaub ntawv hauv pem teb, thiab lwm yam.
Kev lag luam sivxim av fused aluminaabrasive
1. Vim nws qhov kub thiab txias tsis kam, corrosion kuj, thiab siab zog, nws yog siv rau steel casting zawv zawg nozzles, linings (phab ntsa thiab kav dej) ntawm blast furnaces rau smelting tsis tshua muaj thiab precious hlau, tshwj xeeb alloys, ceramics, thiab ironmaking; Lub cev thiab tshuaj lom neeg cov hlab ntsha, lub txim hluav taws xob, thiab cov cua sov- tiv taus thiab oxidation- cov coatings resistant.
2. Vim nws cov hardness siab, zoo hnav tsis kam, thiab siab zog, nws yog siv nyob rau hauv tshuaj systems rau ntau yam reactor hlab ntsha thiab pipelines, tshuaj twj tso kua mis Cheebtsam; mechanical qhov chaw, ntau yam pwm xws li hlau kos duab tuag thiab xaum txhuas extrusion tuag; cov cuab yeej txiav, pwm abrasives, cov ntaub ntawv mos mos, tib neeg cov pob qij txha, sealing pwm rings, thiab lwm yam.
3. Corundum rwb thaiv tsev cov ntaub ntawv, xws li lub teeb corundum cib, hollow corundum spheres, thiab fiber ntau cov khoom, yog dav siv nyob rau hauv lub cub tawg phab ntsa thiab ru tsev ntawm ntau yam siab - kub furnaces thiab kilns, muab ob qho tib si siab - kub thiab rwb thaiv tsev.
4. Tsis tas li ntawd, xim av aluminium oxide kuj tuaj yeem siv rau hauv kev kho dej thiab kev ua kom huv. Nov yog daim ntawv thov tshiab rau abrasives. Nws siv granular abrasive ua qhov nruab nrab hauv qab ntawm lub txaj lim kom lim dej los yog dej khib nyiab. Nws yog ib yam tshiab ntawm cov khoom siv lim dej hauv tsev thiab txawv teb chaws, thiab tshwj xeeb tshaj yog tsim rau cov uas tsis yog -ferrous hlau ore beneficiation thiab roj drilling av nkos hnyav tus neeg saib xyuas.
5. Brown fused alumina kuj tseem tuaj yeem siv los ua cov khoom siv ua haujlwm, xws li hauv cov tsheb nres tsheb, cov log tsheb tshwj xeeb, thiab cov khoom tsim tshwj xeeb. Nws tuaj yeem siv los ua cov khoom hnav-cov khoom siv tiv thaiv rau kev tsim cov kev loj pavements, tshav dav hlau runways, docks, chaw nres tsheb, cov plag tsev, thiab cov chaw ua si.
6. Nws muaj polishing thiab sib tsoo zog, thiab yog tsuas yog siv rau hull polishing thiab xeb tshem tawm, zoo polishing ntawm optical iav thiab lo ntsiab muag, pob zeb carving thiab sandblasting, thiab lwm yam.
Cov txheej txheem los txhim kho qhov zoo ntawmxim av aluminium oxideabrasive
1. Txhim khu kev tswj kev cia. Feem ntau, xim av fused alumina tuaj yeem ua pov tseg vim kev cia tsis raug. Raws li cov khoom siv abrasive, nws muaj ntau qhov me me thaum lub sij hawm calcination txheej txheem. Yog hais tias nws ntsib lub caij los nag, noo noo yuav nkag mus rau hauv cov khoob no. Lub sijhawm no, xim av aluminium oxide abrasive yuav muaj ntau yam dej noo, hydrolysis, xeb, thiab lwm yam, uas yuav cuam tshuam rau nws qhov zoo.
2. Kev hloov kho cov duab ntawm cov xim av fused alumina hais los ntawm kev kho cua sov lossis tshuaj pleev xim. Tsuas yog kev txhim kho particle zoo los txhim kho kev ua haujlwm abrasive tsis txaus rau kev sib tsoo cov cuab yeej, thiab kev kho tshuaj lom neeg yog kim thiab ua rau muaj kuab lom. Yog li ntawd, kev kho cua sov ntawm cov xim av aluminium oxide abrasives tau dhau los ua txoj kev siv dav rau kev txhim kho abrasive zoo.
3. Tsis txhob khaws nrog lwm yam khoom. Brown fused alumina muaj ntau capillaries. Yog tias khaws cia nrog lwm yam khoom, impurities yuav nkag mus rau hauv cov hlab ntsha, txo cov purity ntawm cov xim av aluminium oxide thiab yog li cuam tshuam rau nws qhov zoo.
