Xaiv cov khoom siv xuab zeb
Cov yam tseem ceeb uas cuam tshuam rau kev ua tiav sanding tsis yog tsuas yog qhov loj ntawm cov ntawv xuab zeb tab sis kuj yog hom abrasive.
Qee hom grits ua haujlwm zoo dua nrog cov ntaub ntawv du thiab xuab zeb (piv txwv li, ntoo thiab hlau).
Cov tuam txhab lag luam feem ntau sau cov khoom tsim nyog tshaj plaws rau kev xuab zeb ntawm lawv cov khoom lag luam, tab sis ua ntej peb mus yuav khoom, nws yuav pab tau ntau dua rau kev ua haujlwm ntoo kom paub cov khoom siv rau cov ntawv xuab zeb.
Corundum: Lub ntuj lis, corundum abrasive ntawv feem ntau yog siv los tshem tawm corrosion thiab polish steel thiab lwm yam hlau. Cov npoo ntawm nws cov nplej yuav ntse heev rau cov ntoo sanded.
Garnet: Garnet yog lwm cov khoom ntuj uas yog me ntsis softer dua emery thiab muaj cov npoo sib npaug uas ua kom tiav smoother, tab sis qhov no kuj txhais tau tias sanding qeeb dua thiab daim ntawv yuav hnav sai dua, ua rau nws zoo heev rau kev xaiv sanding zaum kawg.
Alumina-Zirconia: Cov khoom siv hluav taws xob ruaj khov no yog qhov zoo rau kev deburring hlau thiab rau thawj zaug ntxhib sanding ntawm ntoo. Thaum sanding hlau nrog zirconia alumina, cov grit tau ntse dua yog li koj tsis tas yuav hloov cov ntawv xuab zeb ntau zaus.
Aluminium Oxide: Aluminium oxide yog cov khoom siv hluavtaws zoo heev rau kev xuab zeb thiab polishing txhua hom hlau, suav nrog tooj liab thiab hlau alloy, thiab yog lwm hom ntawv xuab zeb siv rau kev ua haujlwm ntoo. Qhov no yog hom ntawv tshaj plaws uas siv hauv lub zog sanders. Alumina yog ruaj dua li daim ntawv garnet tab sis muaj qhov tsis zoo.
Silicon Carbide: Silicon carbide yog ib qho nyuaj abrasive siv feem ntau rau kev txias los yog "ntub sib tsoo" hlau nrog dej ua lub roj nplua nyeem. Txawm hais tias qee qhov kev ua tiav tiav siv cov ntawv silicon carbide, nws tsis yog siv los ntawm cov neeg ua haujlwm ntoo thiab tuaj yeem siv rau sanding hlau woodworking cov cuab yeej.
Ceramic: Ceramic yog ib qho nyuaj heev. Nws tuaj yeem siv rau kev tshem tawm sai ntawm cov ntoo, xws li siv cov sanders thiab grinders. Nws yog qhov ruaj thiab kim tab sis tsis tsim qhov chaw du heev, yog li ceev faj thaum siv cov ntawv xuab zeb vitrified, tshwj xeeb tshaj yog nrog cov plywood thiab veneers, vim lawv tuaj yeem xuab zeb sai sai thiab rhuav tshem cov txheej txheej.
