Qhov taw qhia txog kev muaj txiaj ntsig zoo pob zeb diamond micro hmoov

Cov cuab yeej ua haujlwm ntawm lub siab zoo pob zeb diamond micro muaj cov khoom siv sib txawv, xws li polishing, sib tsoo, txiav, thiab lwm yam). Cov hauv qab no yog qhov ntsuas cov ntsiab lus thiab yuav tsum tau ua rau kev teeb tsa cov txiaj ntsig zoo:

 

1, particle loj xa thiab cov cim tsis sib xws
01) qhov loj me me
Lub particle loj ntawm pob zeb diamond micro hmoov feem ntau {{}}. {}. {1}}}

• POLISHING: Siv Micro Powerders xws li 0-0. 5 microns}}} microns kom txo cov khawb thiab txhim kho saum npoo du.
• Sib tsoo: micro hmoov li cas los ntawm 5-10 microns}}} micrming haum, ntsuas kev ua haujlwm thiab qhov zoo.
• Kev sib tsoo zoo: {20-30 micron micro micro muaj peev xwm txhim kho kev sib tsoo sib tsoo.

 

02) tus cwj pwm ntawm particle loj faib

• D10: Qhov kev faib tawm ntawm 10% sib raug rau cov particle loj, xav txog kev faib ua feem ntawm kev sib txig sib luag. Nws yog ib qho tsim nyog los tswj cov kev sib faib ntawm cov khoom zoo kom tsis txhob muaj tsawg hauv kev sib tsoo hauv kev sib tsoo.
• D50 (median lub taub): sawv cev rau nruab nrab particle loj, uas yog tus tseem ceeb ntawm particle loj faib thiab cuam tshuam ncaj qha rau kev ua haujlwm thiab raug.
• D95: Txheeb xyuas qhov loj me me sib haum rau 95% ntawm kev faib tawm, tswj cov coarse particle cov ntsiab lus (yog tias D95 ntau dua tus qauv, nws yuav ua rau khawb ntawm lub workpiece).
• MV (ntim nruab nrab qhov loj me me): muaj kev cuam tshuam loj heev los ntawm cov khoom loj, siv los soj ntsuam cov ntxhib kawg faib.

 

03) Txuj Ci

Thoob Ntiaj Teb Feem Ntau Cov Qauv Siv Muaj xws li Ansi (xws li D50, D100) thiab ISO (xws li ISO 6106: 2016)

 

2, particle duab thiab cov yam ntxwv saum npoo
01) cov duab parameter

• Roundness: Lub zog txav ze rau yog 1, qhov sib ze ze ntawm cov lus yog cov duab sib dhos, thiab qhov zoo dua cov nyhuv polishing; Hais nrog cov kev sib tw qis (ntau cov npoo thiab cov npoo thiab cov npoo) yog qhov tsim nyog dua rau cov scressioniPating xws li cov hlau hluav taws pom uas yuav tsum tau txiav cov npoo.
• Fleaks cov khoom: hais nrog lub teeb ua kom muaj kev hloov pauv ntau dua 90% yog xav txog cov plaub ya ri, thiab cov kev sib tw yuav tsum muaj tsawg dua 10%; Cov nplaim yeeb daj ntau dhau tuaj yeem ua rau kom pom cov ntsiab lus sib txawv thiab tsis tsim nyog.
• Koob duab ntxwm cov nplai: cov lus nrog cov nam sib piv ntau dua 3: 1 yuav tsum tau nruj me ntsis tswj tau, nrog kev faib ua feem tsis tshaj li 3%.

 

02 Cov Qauv Ntsuas Cov Tshuab 02

• Optical tsom iav: Haum rau kev saib cov duab ntawm cov khoom loj dua 2 microns.
• Kev Ntsuas Hluav Taws Xob Cov metopon me me (SEM): Siv rau Morpholog tsom xam ntawm nanoscale ultrafine hais

 

3, purity thiab impurity tswj
01) Cov ntsiab lus impurity

• Diamond purity must be>99%, thiab cov hlau thiab tooj hlau thiab tooj liab) thiab cov tshuaj phom sij (leej faj thiab chlorine) yuav tsum tau nruj me ntsis tswj hwm qis dua 1%.
• Sib nqus impurities yuav tsum tau tsawg kom tsis txhob agglomeration cuam tshuam txog lub precision polishing nyhuv.

 

02) Sib Nqus Kev Sib Nqus

• Pob zeb diamond Pob Zeb Diamond yuav tsum tau nyob ze rau cov tsis muaj hlau, thiab muaj kev sib nqus cov neeg ua haujlwm sib nqus, uas yuav tsum tau kuaj pom los ntawm hluav taws xob induction thiab lwm txoj kev

 

4, txhais lub cev ua haujlwm
01) Kev cuam tshuam nyuaj

• Cwj pwm kev sib tsoo muaj peev xwm ntawm cov hais, ntsuas qhov tsis tsoo lub sijhawm (lossis semi crushing kuaj, cuam tshuam rau cov cuab yeej sib tsoo.

 

02) thermal stability

• Micro hmoov yuav tsum tau tswj ruaj khov ntawm qhov kub (xws li 750-1000}}} degree) kom tsis txhob muaj lub zog txo los ntawm graphitization lossis oxidation; Feem ntau siv thermogravetric tsom (TGA) txoj kev rau kev kuaj pom.

 

03) microhardness

• Lub microhardness ntawm pob zeb diamond micro hmoov tuaj yeem ncav cuag mus txog 10000 kg \/ hli ², thiab nws yog ib qho tsim nyog yuav tsum tau muaj zog particle

 

5, Daim ntawv thov yuav tsum tau txais
01) Tshuav Ntawm Particle Loj Tshaj Tawm thiab ua cov nyhuv

• Ntxhib hais (xws li High D95) txhim kho kev sib tsoo sib tsoo tab sis txo qis npoo smoothness; Cov nplais zoo (D10 me dua) yog qhov fab ntxeev. Cov khoom faib xov xwm faib tau yuav tsum tau hloov kho raws li kev thov.

 

02) cov duab yoog

• Thaiv cov duab sib tshooj ntau hniav yog qhov tsim nyog rau Resin sib tsoo cov log; Kheej kheej yog tsim nyog rau precision polishing.

 

• 6, kev sim tshuaj thiab cov qauv

01) Kev Pom Zoo Granularity

• Laser differaction txoj kev: dav siv rau micron \/ submicron iab iab iab, nrog cov ntaub ntawv ua haujlwm yooj yim thiab txhim khu kev qha cov ntaub ntawv.
• Kev soj ntsuam txoj kev: tsuas yog siv rau cov lus saum 40 microns.

 

02) cov duab nrhiav

• Particle daim duab analyzer tuaj yeem ntsuas qhov tsis muaj xws li spherericity, txo kev ceeb toom kom pom qhov teeb meem tsis muaj cua

 

lub ntsiab
Cov Khoom Zoo Pob Zeb Ua Zoo Yuav Tsum Tau Pom Cov Particle Loj (D10 \/ D105), Mascetism), thiab lub zog (lub zog, thermal stability). Cov kev lag luam ntau lawm yuav tsum tau ua kom zoo raws li kev thov zoo li cov xwm txheej nrhiav tau xws li laser diffraction thiab electron me mecopy. Thaum cov neeg siv xaiv, lawv yuav tsum sib phim cov khoom ntsuas raws li cov kev xav tau tshwj xeeb (xws li kev ua haujlwm thiab du). Piv txwv, precision polishing yuav tsum tau ua kom tau qhov tseem ceeb tswj d95 thiab roundness, thaum muaj kev sib tsoo ntxhib tau los txhim kho kev ua tau zoo
