Kev sib raug zoo ntawm grit thiab khawb muaj peev xwm

Feem ntau hais lus, qis dua qhov grit (piv txwv li, cov khoom loj dua cov khoom siv), lub zog uas muaj zog dua ntawm cov xuab zeb. Qhov no yog vim tias cov khoom muaj abrasive loj tuaj yeem txiav tob rau saum npoo ntawm workpiece, ua rau tob tob. Conversely, Sandpaper nrog rau cov grit siab dua tau me me abrasive thiab tsis muaj zog dua qhov yuav tsum tawm ntawm qhov chaw ntawm lub workpiece.

Txawm li cas los xij, qhov kev sib raug zoo no tsis yog qhov tseeb. Qhov tseeb, kev muaj peev xwm khawb kuj cuam tshuam los ntawm lwm yam, xws li:

- Hom Abrasive: sib txawv hom abrasives (xws li txhuas oxide, silicon carbide, thiab lwm yam sib txawv, yog li ntau yam sib txawv khawb muaj txawm tias muaj grit yog tib yam.

- Cov khoom siv ua haujlwm: Lub hardness ntawm cov khoom siv ua haujlwm tseem yuav cuam tshuam rau kev khawb qhov peev xwm ntawm cov ntawv xuab zeb. Piv txwv li, cov ntaub ntawv nyuaj dua tuaj yeem tiv taus khawb los ntawm cov ntawv xuab zeb, thaum cov ntaub ntawv softer yog khawb tau yooj yim dua.

- Kev Siv Txoj Kev Pab: Txoj kev uas koj siv Sandpaper yuav cuam tshuam nws lub peev xwm khawb. Piv txwv li, thov siv ntau dua lossis siv cov kev txav nrawm yuav ua rau cov khawb qis.

Yuav ua li cas xaiv txoj cai sandpaper grit

Xaiv lub suab paj nruag txoj cai grit yog nyob ntawm koj cov kev xav tau tshwj xeeb. Ntawm no yog qee qhov kev tso npe sau ua ke thiab lawv pom zoo rau grits:

- Roughing: Yog tias koj yuav tsum tau tshem tawm ntau cov khoom siv sai, koj tuaj yeem xaiv Sandpaper nrog qhov qis dua grit (xws li 100 lossis 200 grit). Cov khau khiab no muaj lub peev xwm khawb tau muaj zog thiab tuaj yeem txiav mus rau hauv qhov chaw ua haujlwm sai sai.
- Kev Ua tiav: Yog tias koj xav tau kom ua tiav qhov chaw du, xaiv cov ntawv xuab zeb nrog cov grit ntau dua (xws li 2000 lossis siab dua grit). Cov ntawv xuab zeb no muaj peev xwm khawb tsis muaj zog thiab tuaj yeem tsim cov nyhuv me me.
- Nruab nrab kev ua: yog tias koj xav tau kev hloov ntawm kev ntxhib thiab xov, xaiv cov xuab zeb nrog rau nruab nrab grit (xws li 500 lossis 1000 grit). Cov phuam da dej no muaj qhov ntsuas me me thiab tuaj yeem sib npaug qhov xav tau kom tshem cov khoom thiab ua tiav qhov chaw du.

Qhov kev sib raug zoo ntawm cov grit ntawm cov xuab zeb thiab nws khawb muaj peev xwm yog qhov nyuaj thiab cuam tshuam nrog ntau yam. Feem ntau hais lus, qis dua ntawm grit, qhov muaj zog dua lub muaj peev xwm ntawm cov xuab zeb; Qhov siab dua cov grit, cov tsis muaj zog ntawm lub peev xwm khawb. Txawm li cas los xij, txoj kev sib raug zoo no tseem cuam tshuam los ntawm cov khoom xws li hom abrasive, cov khoom siv workpiece, thiab txoj kev thov. Yog li ntawd, thaum xaiv cov xuab zeb grit, koj yuav tsum xav txog cov ntsiab lus no ua ke kom tau raws li koj cov kev xav tau tshwj xeeb.
