Cov ntaub ntawv hais txog Coated Abrasives

Coated abrasives xa mus rau abrasives uas siv cov hlua khi los ua cov abrasives mus rau qhov hloov pauv tau yooj yim, los yog hu ua abrasives saj zawg zog.
Abrasives ua los ntawm adhering abrasives mus rau ib tug saj zawg zog substrate (daim ntaub los yog ntawv, thiab lwm yam) nrog ib tug binder. Coated abrasives muaj daim ntawv-puab (lub duab plaub), disc-puab, nplhaib-puab thiab lwm yam tshwj xeeb duab (saib cov duab xim). Lub ntsiab ntau yam yog sandpaper (paper) thiab sanding siv. Lawv feem ntau siv mechanically lossis manually. Lawv tau siv dav rau kev sib tsoo, polishing thiab sib tsoo ntawm cov ntaub ntawv tsis yog xim hlau xws li cov ntaub ntawv hlau, ntoo, ceramics, yas, tawv, roj hmab thiab xim putty. Coated abrasives yog tsim los ntawm peb qhov chaw: abrasives, binders thiab substrates (saib daim duab).
Feem ntau siv abrasives yog cov khoom abrasives xws li corundum, silicon carbide thiab iav xuab zeb, thiab qee zaum ntuj abrasives xws li garnet thiab ntuj corundum kuj siv. Binders muaj xws li tawv kua nplaum, pob txha kua nplaum, casein kua nplaum thiab hluavtaws resin kua nplaum. Cov substrates muaj xws li ntaub, ntawv thiab ntaub-paper composite cov ntaub ntawv. Kev tsim cov txheej txheem ntawm coated abrasives feem ntau suav nrog kev kho substrate, primer txheej, xuab zeb cog, rov txheej (npo), ziab thiab txiav.
Raws li "universal sib tsoo cov cuab yeej", coated abrasives tsis tsuas yog muaj ntau yam kev ua haujlwm thiab kev sib tsoo siab, tab sis kuj tuaj yeem ua tiav qhov tseeb qhov tseeb thiab tsis tshua muaj qhov roughness.
