Particle Size Detection Method Thiab Application Range Of White Corundum Abrasive

Dawb corundum abrasiveyog ib hom kev tsim abrasive, nws txoj kev tsim khoom yog qhov nyuaj heev, ua los ntawm cov txheej txheem smelting tshwj xeeb, thiab tom qab ntawd los ntawm kev sib tsoo thiab shaping, sib nqus sib nqus rau hlau thiab lwm yam txheej txheem, tshuaj xyuas rau hauv ntau qhov me me, qhov dawb corundum particle loj yuav ua li cas. ntes nws? Nov yog cov ntsiab lus tshwj xeeb los piav qhia txog ntau txoj hauv kev:

(1) Kev tshuaj ntsuam xyuas. Qhov zoo: yooj yim, intuitive, cov cuab yeej siv qis, feem ntau siv rau cov qauv ntau dua 40um. Disadvantages: Qhov tshwm sim yog cuam tshuam zoo heev los ntawm tib neeg yam thiab sieve deformation.

(2) Microscope (duab) txoj kev. Qhov zoo: Yooj yim, intuitive, morphologic tsom xam, haum rau nqaim faib (qhov siab tshaj plaws mus rau qhov tsawg kawg nkaus qhov sib piv ntawm tsawg dua 10: 1) ntawm cov qauv. Qhov tsis zoo: cov neeg sawv cev tsis zoo, kev txheeb xyuas cov qauv nrog ntau qhov kev faib tawm yog qhov teeb meem ntau dua, thiab cov qauv qis dua 1um tsis tuaj yeem txheeb xyuas.

(3) Kev daws teeb meem (nrog rau kev sib haum xeeb ntawm lub ntiajteb txawj nqus thiab Lixin kev daws teeb meem). Qhov zoo: maj mam ua haujlwm, ua haujlwm tsis tu ncua ntawm cov cuab yeej, tus nqi qis, qhov raug zoo thiab rov ua dua, ntau yam kev sim. Disadvantages: Lub sij hawm xeem yog ntev dua thiab kev ua haujlwm nyuaj dua.

(4) Txoj kev tiv thaiv. Qhov zoo: Tus naj npawb ntawm cov khoom tuaj yeem ntsuas tau hauv kev ua haujlwm maj mam, lub tswv yim sib npaug yog qhov tseeb, qhov nrawm nrawm, thiab qhov tseeb yog qhov zoo. Qhov tsis zoo: Nws tsis haum rau kev ntsuas particle tsawg dua 0.1um, thiab nws yog ib qho teeb meem los hloov lub qhov me me rau cov qauv nrog qhov dav particle loj.

(5) Laser txoj kev. Qhov zoo: kev ua haujlwm yooj yim, ntsuas nrawm nrawm, ntsuas ntau yam, rov ua tau zoo thiab raug, ntsuas hauv online thiab ntsuas qhuav. Qhov tsis zoo: Cov txiaj ntsig tau cuam tshuam zoo heev los ntawm cov qauv kev faib khoom, tus nqi ntawm cov cuab yeej yog siab, thiab kev daws teeb meem tsawg.

(6) Electron microscopy. Qhov zoo: tsim nyog rau kev sim cov khoom tshiab ultra-tshiab lossis txawm tias nanoparticles, kev daws teeb meem siab, morphology thiab cov qauv kev soj ntsuam tuaj yeem ua tau, qhov tsis zoo: cov qauv me me, cov neeg sawv cev tsis zoo, kev ntsuas tau raug cuam tshuam rau tib neeg yam, thiab cov cuab yeej yog kim.

(7) Txoj kev Photoresistance. Qhov zoo: kev sim yooj yim thiab ceev, tuaj yeem ntsuas cov khoom hauv cov kua lossis roj, kev daws teeb meem siab. Disadvantages: tsis haum rau cov qauv nrog particle loj tsawg dua 1umde, lub kaw lus yog ntau tshwj xeeb, tsuas yog haum rau ntsuas cov plua plav, cov pa phem los yog cov tshuaj uas tau diluted, thiab tsis ntau rau cov hmoov.

(8) Txoj kev ua pa. Qhov zoo: Tus nqi ntsuas qis. Cov khoom siv hmoov tuaj yeem ntsuas tsis tau dispersing tus qauv. Qhov tsis zoo: tsuas yog qhov nruab nrab particle loj tuaj yeem tau txais, thiab qhov loj me me tsis tuaj yeem ntsuas tau; Tsis txhob ntsuas tsawg dua 5um hmoov zoo.

(9) X-ray me lub kaum sab xis scattering txoj kev. Siv rau kev ntsuas particle loj ntawm nano-scale hais.

(10) Photon correlation spectroscopy (dynamic light scattering method). Siv rau kev ntsuas particle loj ntawm nano-scale hais.

Dawb corundum abrasivesyog ua los ntawm bauxite thiab graphite electrode, thiab yog tsim los ntawm tshiab ultrafine hmoov technology. Thaum lub sijhawm tsim khoom, cov khoom siv raw yuav tsum tau ntxiv thiab nplawm, tsim, thiab raug rho tawm haujlwm ntawm qhov kub thiab txias. Kev siv cov yam ntxwv ntawm dawb corundum: siab refractoriness, ruaj khov kev ua haujlwm ntawm qhov kub thiab txias, tsis tawg. Nws tsis hmoov. Corrosion kuj, siab hardness, tab sis kuj muaj ib tug tej yam toughness. Dawb corundum yog tsim rau txhua yam ntawm cov ntaub ntawv refractory nyob rau hauv kub kub ntau lawm. Nws yog siv dav hauv kev sib tsoo ntawm cov tshuaj, iav thiab ntau yam ntaub ntawv hlau, thiab tseem tuaj yeem siv rau hauv kev pom cov dej zoo.
