Silicon carbide 88% vs 90%, tib grit - uas zoo dua rau precision polishing?

INprecision polishing ntawm hlau, optics thiab precision ceramicsLub abrasive yuav tsum muab qhov huv tshaj plaws, feem ntau zoo ib yam thiab ua kom tiav qhov chaw tiav. Silicon carbide (SiC) feem ntau yog siv vim nws hardness, hnav tsis kam, thiab muaj peev xwm tswj cov khoom tshem tawm cov qauv. Thaum sib pivSiC 88% purity thiab SiC 90% purity nrog tib grain lojQhov sib txawv ntawm 2% zoo li me me, tab sis nyob rau hauv cov xwm txheej ntawm precision machining nws yuav txiav txim siab: nws cuam tshuam rau kev huv ntawm kev txiav, qhov tsis muaj kev suav thiab, vim li ntawd, qhov zoo ntawm qhov kawg gloss thiab pob tshab ntawm qhov chaw.

Tuam txhabZhenAn, muaj30 xyoo ntawm kev paubCov khoom siv silicon carbide rau cov txheej txheem tiav tiav thiab yog ISO / SGS ntawv pov thawj, tshuaj xyuas kom meej tias qib purity muab qhov txiaj ntsig zoo tshaj plaws hauv kev polishing.

1. Dab tsi yog qhov tseem ceeb hauv precision polishing?

Hauv precision machining, lub hom phiaj ntawm - yog kom tau qhov chaw:

Nrogyam tsawg kawg nkaus(scratches, dents, inclusions);

Nroguniform roughnessnyob rau theem submicron;

tsis muaj abrasive residues lossis cov khoom siv tshuaj tiv thaiv uas ua rau lub teeb tawg (hauv optics) lossis corrosion (hauv hlau);

Nrogsiab reproducibilitytau los ntawm batch mus rau batch.

Qhov zoo ntawm polishing nyob ntawm tsis yog tsuas yog nyob rau ntawm grain loj, tab sis kuj nyob rauabrasive purity​ - tshwj xeeb tshaj yog rau tus nqi thiab hom impurities uas tuaj yeem tsim cov khoom muag muag lossis cov nplaum nplaum uas nyob hauv micropores ntawm qhov chaw.

2. Tib grit - yog vim li cas kev huv huv tseem ceeb?

Yog hais tias lub grain loj (particle loj) yog tsau, ces lub ntsiab ntawm cov txheej txheem yog exerted los ntawm:

Kev sib xyaw ntawm impurities: hauv SiC 88% - txog 12% impurities (silicon dioxide, dawb carbon, hlau oxides), hauv SiC 90% - tsuas yog ~ 10%.

Particle zoo thiab lub zog: Impurities txo cov nplej muaj zog thiab ua rau tsis sib xws.

Tshuaj inertness: Cov impurities tuaj yeem tawm hauv cov yeeb yaj kiab nyias lossis oxidize, tsim kom muaj qhov tsis xws luag.

Yog li, nrog tib grain loj, nws yogKev huv huv txiav txim siab qhov ruaj khov thiab ua haujlwm zoo ntawm polishing.

3. Yuav ua li cas impurities impair zoo polishing

Irregular crushingcov

Cov impurities tsim cov ntsiab lus tsis muaj zog hauv SiC nplej, thiab thaum muaj kev cuam tshuam, kev sib xyaw ntawm cov hmoov av zoo heev (tsis muaj zog tshem tawm) thiab cov tawg loj (qhov sib sib zog nqus khawb) yog tsim.

Taw qhia txog cov khoom rau hauv qhov chawcov

Mos impurities (xws li SiO₂, carbon) tuaj yeem nkag mus rau hauv microcracks lossis pores, ua rau lub teeb tawg (optics) lossis txheej txheej laus (hlau).

Residual filmscov

Qee qhov impurities, tom qab kev cuam tshuam nrog cov khoom siv, tawm cov yeeb yaj kiab nyias nyias uas cuam tshuam nrog kev tau txais daim iav ci.

Instability ntawm kev tshem tawmcov

Qhov sib txawv hardnesses ntawm cov feem ntau ua rau kev tshem tawm tsis sib xws thiab xav tau kev hla ntxiv kom tshem tawm qhov tsis xws luag.

4. Qhov zoo ntawm SiC 90% hauv precision polishing

Uniform crushing​ - SiC nplej khaws lawv cov duab thiab hardness, muab cov micro tshem tawm ruaj khov.

Kev siv tsawg kawg nkaus​ - Cov nplej huv si tsis tshua muaj feem cuam tshuam rau ntawm qhov chaw, txo qhov tsis xws luag.

Tsis muaj cov yeeb yaj kiab seem​ - kev tsis sib haum xeeb tsawg, qhov chaw tiav yog ze rau qhov zoo tshaj plaws tom qab lub ntsiab polishing.

Kev kwv yees tau tshwm sim​ - zoo tib yam abrasive ua hauj lwm ntawm tag nrho ib feem, tsawg dua kev hloov thiab hloov.

Qhov no yog qhov tseem ceeb tshwj xeeb rauoptical Cheebtsam, hniav nyiaj hniav kub, precision hlau qhov chaw thiab kev kho mob cog, qhov twg txawm nanometer-scale defects cuam tshuam functionality.

5. Kev sib piv ntawm cov yam ntxwv nrog tib lub grain loj

Xaus: attib grain lojcovSiC 90% muab qhov txiaj ntsig zoo tshaj plaws hauv kev ua polishing, raws li nws muab ib tug huv si, ntau uniform thiab ntxaum txheej txheem nto nrog tsawg lub sij hawm.

6. Cov lus pom zoo

Rauhigh-precision optics, laser tshuab, khoom kho mob​ - xaiv 90% SiC kom txo qis kev tawg thiab qhov tsis xws luag.

Rauhniav nyiaj hniav kub thiab cov khoom dai​ - SiC 90% tso cai rau koj ua tiav daim iav tiav sai dua nrog kev ua haujlwm tsawg dua.

Ntawmautomated polishing kab​ - abrasive ruaj khov txo qhov kev hloov pauv thiab ua kom cov qoob loo nce ntxiv.

Xav txogtus nqi thiab kev ua haujlwm: Tus nqi siab dua me ntsis ntawm SiC 90% yog offset los ntawm lub sijhawm ua haujlwm luv dua thiab cov khoom siv tsawg dua.

7. Case Study

Optical manufactory, uas tsim cov lo ntsiab muag los ntawm iav thiab sapphire, hloov los ntawm SiC 88% mus rau SiC 90% (tib yam grain loj):

Txo tus naj npawb ntawm "cov ntsiab lus tawg" los ntawm 70% hauv kev sim kis lub teeb.

Txo tus naj npawb ntawm polishing kawg dhau los ntawm 50%.

Ua kom cov qoob loo ntawm cov khoom tsim nyog los ntawm 88% mus rau 97%.
