Ua ntej peb mus rau hauv daim ntawv qhia txog qhov chaw tiav, cia peb nkag siab txog qhov chaw tiav txhais li cas.
Kev ua kom tiav ntawm qhov chaw yog hais txog cov txheej txheem ntawm kev hloov pauv ntawm cov hlau nto uas cuam tshuam nrog kev tshem tawm, ntxiv, lossis rov ua dua. Nws yog kev ntsuas ntawm tag nrho cov qauv ntawm cov khoom nto uas txhais los ntawm peb yam ntxwv ntawm qhov roughness ntawm qhov chaw, wavyness thiab lay.
Qhov roughness ntawm qhov chaw yog qhov ntsuas ntawm tag nrho cov kev tsis sib xws ntawm qhov chaw. Thaum twg cov kws kho tshuab tham txog "qhov chaw tiav," lawv feem ntau hais txog qhov roughness ntawm qhov chaw.
Qhov nthwv dej yog hais txog qhov chaw uas nws qhov sib nrug loj dua qhov ntev ntawm qhov roughness ntawm qhov chaw. Thiab qhov lay yog hais txog qhov kev taw qhia uas cov qauv nto tseem ceeb mus. Cov kws kho tshuab feem ntau txiav txim siab qhov lay los ntawm cov txheej txheem siv rau qhov chaw.
3.2 qhov tiav ntawm qhov chaw txhais li cas
Ib qho 32 qhov chaw tiav, tseem hu ua 32 RMS tiav lossis 32 microinch tiav, hais txog qhov roughness ntawm cov khoom siv lossis cov khoom. Nws yog kev ntsuas ntawm qhov nruab nrab qhov siab hloov pauv lossis kev hloov pauv hauv cov qauv ntawm qhov chaw. Hauv qhov xwm txheej ntawm 32 qhov chaw tiav, qhov siab hloov pauv feem ntau yog nyob ib puag ncig 32 microinches (lossis 0.8 micrometers). Nws qhia txog qhov chaw du nrog cov qauv zoo thiab tsawg kawg nkaus imperfections. Tus lej qis dua, qhov zoo dua thiab du dua qhov chaw tiav.
Dab tsi yog RA 0.2 qhov tiav tiav
RA 0.2 qhov tiav ntawm qhov chaw yog hais txog kev ntsuas qhov roughness ntawm qhov chaw. "RA" sawv cev rau Roughness Average, uas yog ib qho parameter siv los ntsuas qhov roughness ntawm qhov chaw. Tus nqi "0.2" sawv cev rau qhov roughness nruab nrab hauv micrometers (µm). Hauv lwm lo lus, qhov tiav ntawm qhov chaw nrog tus nqi RA ntawm 0.2 µm qhia txog qhov du thiab zoo nkauj ntawm qhov chaw. Hom kev tiav ntawm qhov chaw no feem ntau yog ua tiav los ntawm kev ua haujlwm precision lossis polishing txheej txheem.
ZhongRui TubeElectropolished (EP) Seamless Raj
Cov Hlau Stainless Hlau Electropolishedsiv rau biotechnology, semiconductor thiab hauv kev siv tshuaj. Peb muaj peb tus kheej cov khoom siv polishing thiab tsim cov raj electrolytic polishing uas ua tau raws li qhov xav tau ntawm ntau qhov chaw nyob rau hauv kev coj ntawm pab pawg neeg Korean.
