Cov txheej txheem tsim kho
- Kev kho av tiaj tiaj: xuab zeb kom huv, qhov chaw hauv paus yuav tsum qhuav, tiaj tus, tsis muaj lub nruas khoob, tsis muaj kev xuab zeb loj;
- Cov khoom siv ua ntej: ob npaug ntawm cov khoom sib xyaw raws li qhov ntau ntawm qhov sib piv uas tau teev tseg (kev sib hloov hluav taws xob 2-3 feeb), nrog rau lub log lossis scraper;
- Hauv cov tshuaj pleev xim: ob-feem sib xyaw raws li qhov ntau ntawm cov xuab zeb quartz tau teev tseg (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev siv scraper;
- Hauv cov xim pleev xim: ob-feem sib xyaw raws li qhov ntau ntawm kev sib xyaw (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev siv scraper;
- Txheej sab saum toj: tus neeg sawv cev rau xim thiab tus neeg sawv cev kho raws li qhov ntau ntawm qhov sib piv (kev sib hloov hluav taws xob rau 2-3 feeb), nrog rau kev txau lossis khawb hniav nrog cov hniav tsim.
