Tuaj yeem ntaus nrig ntawm cov xuab zeb thiab polishing daim ntaub yuav hloov pauv sib hloov pauv?

1. Muaj qhov sib txawv hauv kev ua haujlwm.

Misionallographic Sandpaper: Nws tsuas yog siv nyob rau hauv cov ntxhib sib tsoo thiab zoo sib tsoo theem ntawm cov qauv kev npaj. Los ntawm kev sib txhuam ntawm cov khoom siv nyuaj (xws li Silicon Carbide, txheej txheem ua haujlwm, kev ua cov cim, lossis deformation txheej los ntawm cov txheej txheem yav dhau los. Nws lub hom phiaj tseem ceeb yog kom sai thiab tusyees txo cov rougness saum npoo av, muab lub hauv paus tiaj tiaj rau kev ua polishing tom qab.
Polishing daim ntaub: nws yog ib qho cuab yeej siv nyob rau theem kawg, feem ntau yog siv nyob rau hauv kev sib txuas nrog polishing paste (muaj micrasives thiab lubricants). Nws cov qauv muag cov qauv tuaj yeem haum rau cov av zoo nkauj hauv cov tshuaj txhuam hniav me me, thaum kawg}} {3} Zoo li nplaim.

 

2. Qhov sib txawv ntawm cov qauv thiab ua haujlwm ntawm cov ntsiab cai

Sandpaper: Cov khoom siv nyuaj ua kom ruaj khov yog tsau rau ntawm cov ntawv pov tseg (xws li daim ntawv lossis daim ntaub), thiab cov ntaub ntawv raug tshem tawm los ntawm txhua yam kev sib tsoo. Cov Abrasive hais ncaj qha hu rau cov neeg ua haujlwm, uas yog qhov txiaj ntsig zoo tab sis nquag ua rau cov khawb.
Polishing daim ntaub: Ib daim ntaub hloov tau ntaub (xws li Flannel, Nylon) haum cov abrannel zoo nyob rau hauv lub polishing muab tshuaj txhuam los ntawm txoj kev ruaj ntseg ntawm lub microprotrusions. Ua ke nrog cov tshuaj lom neeg ntawm cov roj nplua nyeem (xws li oxidation, xaus lus), nws ua tiav qis -} kev hloov kho qhov chaw.

 

3. Txwv tsis pub tshaj ntawm kev hloov pauv

Hloov chaw rau cov xuab zeb rau polishing sib dhos: nyob rau hauv daim ntaub ntxhib sib tsoo, yog tias polishing daim ntaub yog siv, vim tias tsis muaj cov khoom tsis muaj zog, nws tsis tuaj yeem siv cov khoom siv. Nyob rau hauv lub kawg polishing theem, yog tias cov xuab zeb yog siv, txawm tias muaj cov grit zoo nkauj (xws li 2000 #), nws tsis kam ntsib daim iav {{2} Zoo li qhov yuav tsum tau ua.
Hloov chaw polishing rau Sandpaper: Tus qauv sib tsoo ntawm cov ntaub ntawv sib tsoo yog ib txwm muaj kev sib tsoo sib tsoo, ua rau muaj kev sib tsoo sab nraud. Ntxiv mus, cov tshuaj lom neeg ntawm cov painishing yog qhov tsis muaj txiaj ntsig zoo hauv cov kev sib tsoo ntxhib theem, lub sij hawm ntev ua lub sijhawm ua.

 

4. Kev sib piv hauv cov xwm txheej tshwj xeeb

Yog tias qhov ua tau zoo nyob rau hauv yog tsis siab (xws li tsuas yog soj ntsuam co coarse (xws li lub sijhawm sib tsoo yuav tsum tau txuas ntxiv kom txo qhov tob ntawm khawb. Hloov siab, yog tias siab - precision tsom xam, xws li nplej conisher → polishing daim ntaub yuav tsum ua nruj me ntsis; Txwv tsis pub, nws yuav ua rau cov khoom cuav lossis cov ntaub ntawv distortion.
