Ntau Meshes Ntawm Sandpaper Thiab Cov Lus Qhia Rau Kev Siv
1. Qhov hnyav ntawm daim ntawv abrasive
Chav tsev qhov hnyav ntawm daim ntawv abrasive (piv txwv li, AW yog 65g / cm²) cuam tshuam rau qhov yooj, toughness, thiab mechanical resistance ntawm daim ntawv abrasive. Los ntawm lub teeb mus rau hnyav, lawv yog AW (A hauv paus hnyav), CW, DW, EW, FW, thiab lwm yam.
AW yog daim ntawv lightest rau phau ntawv sanding, CW yog qhov thib ob, thiab abrasive ntawv haum rau phau ntawv sanding thiab lub teeb mechanical sanding (portable vibrating sander), saum toj no DW, yog mechanical sanding paper, EW, FW yog hnyav sanding ntawv.
2. Abrasive ntawv raw khoom
Cov khoom siv abrasive feem ntau yog cov khoom siv dag zog, feem ntau yog alumina, thiab silicon carbide. Alumina (dub hlau liab rau lub teeb hlau liab, cim AA lossis A) feem ntau yog ua raws li cov ntawv abrasive tsis tu ncua rau cov xuab zeb qhuav, thaum silicon carbide (dub, cim CC) feem ntau yog ua rau dej-resistant abrasive ntawv.
3. Tus naj npawb ntawm cov ntawv abrasive
Hais txog tus naj npawb ntawm meshes ib square inch. Piv txwv li, 100 # silicon carbide abrasive daim ntawv yog faib nrog 100 * 100 abrasive hais nyob rau hauv "1 * 1" cheeb tsam.
Muaj ob hom ntau thiab tsawg: American loj thiab European loj (nrog P lo lus ntxiv). Ob leeg muaj qhov loj me me ntawm 180 # thiab 500 #, tab sis qhov loj me ntawm cov ntawv xuab zeb Asmeskas tsuas yog 600 #, uas yog hais txog finer tshaj P1200, thiab European sandpaper yog zoo li P3000 mesh. Tam sim no muaj 4000 mesh thiab 5000 mesh.
4. Emery Ntaub
Nws yog tib yam li daim ntawv abrasive, tshwj tsis yog tias cov khoom siv rov qab txawv ntawm daim ntawv abrasive. Raws li kev xaiv ntawm daim ntawv abrasive lossis daim ntaub abrasive, nws nyob ntawm tus kheej nyiam, tab sis muaj cov qauv ntawm cov ntawv abrasive hloov cov ntaub abrasive.
Rau DIY abrasive ntawv, nws txaus los npaj 40 #, 60 #, 100 #, 150 #, 180 #, 240 #, 320 #, thiab 360 #.
Yog tias cov khoom siv yog ntoo core board thiab veneer, nws tuaj yeem sanded nrog abrasive ntawv pib ntawm 150 #. Thaum yuav tsum tau kho qhov chaw zoo, ntxiv 400, 600,800,1000 meshes tuaj yeem yuav.
Tam sim no, ntau tus neeg nyiam cov rooj tog qub qub. Txhawm rau ua kom tau raws li peb cov kev xav tau zoo nkauj, peb tuaj yeem ua cov rooj tog qub qub rau peb tus kheej. Ua ntej, siv hlau ntsia hlau lossis cov screws, thiab lwm yam, kom ib txwm ntaus cov ntoo saum npoo los tsim cov duab hauv npauj kom ua tiav cov nyhuv qub.
Tom qab ntawd siv cov ntaub ntawv tshem tawm cov caws pliav ntawm lub rooj, thiab tom qab ntawd siv cov ntawv xuab zeb ntxhib los ua cov plaub fab ntawm lub rooj thiab sab saum toj ntawm lub rooj tsawg kawg kom ua tiav cov txiaj ntsig ntawm ntuj hnav, koj tuaj yeem siv cov cuab yeej xws li lub hau ntswj. thiab bolts rau kais rau saum npoo ntawm cov rooj tog me ntsis kom ua rau pob thiab kev nyuaj siab, zawj cov cim lossis khawb kuj tuaj yeem muab cov hlau carving riam kom ua tiav cov nyhuv npauj.
Nyob rau hauv txoj kev no, ib daim ntawm cov rooj tog uas muaj kev zoo nkauj antique yog tsim, thiab tej zaum koj cov qhua yuav nug koj seb lub dynasty no rooj tog yog los ntawm! Hauv cov txheej txheem no, daim ntawv abrasive tau ua lub luag haujlwm loj. Tsuas yog los ntawm kev ua haujlwm zoo ntawm ntuj hnav thiab tsim kua muag, peb tuaj yeem ua tiav qhov zoo tshaj plaws antique nyhuv, txwv tsis pub nws yuav yog cov khoom siv niaj hnub rhuav tshem los ntawm cov menyuam yaus tsis zoo.
