Cov txheej txheem tsim kho
1. 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;
2. Primer: ob chav tivthaiv raws li qhov ntau ntawm qhov sib piv sib xyaw (kev sib hloov hluav taws xob 2-3 feeb), nrog rau lub log lossis scraper;
3. Hauv cov xim pleev xim: ob feem sib xyaw raws li qhov ntau ntawm cov xuab zeb quartz do (kev sib hloov hluav taws xob rau 2-3 feeb), nrog rau kev siv scraper;
4. Hauv cov xim pleev xim: ob feem sib npaug raws li qhov ntau ntawm kev sib xyaw (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev siv scraper;
5. Lub tsho sab saum toj: tus neeg sawv cev xim thiab tus neeg sawv cev kho raws li qhov ntau ntawm qhov sib piv (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev dov lossis txau tshuaj.
