Ib tus kws tshaj lij hauv kev sib tsoo thiab ua polishing

Sandpaper yog ib qho khoom siv rau kev sib tsoo thiab polishing, nrog nws cov lus zais hauv cov khoom thiab grit loj. Lub hauv paus tuaj yeem yog ib daim ntawv lossis ntaub. Ntawv -} Raws li cov xuab zeb yog kev lag luam tab sis nquag ua kua muag, ua rau nws haum. Daim ntaub -} Raws li cov suab paj nruag, xws li cov paj rwb lossis hluavtaws muaj zog, yog ntau ruaj thiab tshwj xeeb rau lub tshuab sib tsoo. Cov abrasive yog cov tseem ceeb tivthaiv. Aluminium oxide (liab) yog qhov nyuaj thiab haum rau ob qho ntoo thiab hlau. Silicon carbide (dub) yog ntse thiab zoo ntawm kev sib tsoo hlau thiab iav. Zirconium aluminium (xiav) yog hnav - tiv taus thiab ua tau zoo ntawm kev kub ceev. Pob zeb diamond xuab zeb yog siv rau cov tsis tshua muaj zog zoo polishing ntawm gemstones thiab pob zeb khoom.

Mesh loj txiav txim siab ntawm coarseness. Tus nqi ntawm 40 - 120 mesh yog siv rau kev sib tsoo me me, uas yog siv cov chaw sib tsoo kom zoo rau cov xuab zeb smoothing rau cov xuab zeb zoo rau kev ua kom zoo rau kev ua kom zoo. Sandpaper nrog mesh loj ntawm 1200 lossis siab dua yog qhov zoo heev thiab tau siv tshwj xeeb rau kev ua tiav daim iav {}} zoo li ua tiav. Thaum xaiv Sandpaper, nws yog ib qho tseem ceeb rau "kho cov tsos mob": Pib nrog coarse cov burrs thiab tom qab ntawd maj mus rau cov qhab nia zoo nkauj. Rau kev sib tsoo hlau, silicon carbide yog cov nyiam, ua ke nrog nruab nrab kom zoo mesh. Rau lub tsheb cov xim av lossis iav, siv cov dej dej sandpaper, uas ntub kev sib tsoo sib tsoo txo ​​cov plua plav thiab muaj txiaj ntsig ntau dua. Thaum siv, tsis txhob thov kev ua haujlwm ntau dhau los tiv thaiv kev kub ntxhov thiab hnav ntawm cov xuab zeb. Thaum cov dej sib tsoo, tswj cov dej kom muaj kev tswj kom zoo. Maj mam zuj zus los ntawm coarse kom zoo rau kev sib tsoo kom ua tiav ib qho du, daim iav-zoo li nto, zoo li cov xim zoo dua.
