1. Lub npuaj kub kub feem ntau yog ua los ntawm tooj liab-kub hmoov lossis anodized aluminium (daj) hmoov ntxiv rau cov roj nplaum txhawm rau txhawm rau npaj cov ntawv luam ntawv, uas zoo li kub tom qab luam ntawv thiab muaj xim hlau;
2. Xaiv cov khoom npaj:
2.1 Xaiv cov xim ntoo nrog cov siab ntim (TG yog xaiv raws li cov khoom siv);
2.2 Xaiv lub hmoov nrog qhov xav kom tau zoo, feem ntau ntsuas los ntawm tus naj npawb ntawm meshes;
2.3 Xaiv cov xim raug thiab luster (feem ntau muab faib ua cyan teeb, lub teeb liab, lub teeb daj, cyan-liab teeb);
2.4 Xaiv cov tuab tuab (dav dav tuab yog txaus)
2.5 Xaiv cov antioxidants (qee cov resins tau twb tau kho nrog antioxidants thiab tsis tas yuav ntxiv);
2.6 Nrhiav tus qauv tsim nyog raug rho tawm;
3. Tes taws los qhia txoj kev:
Ua ntej tshaj, do thiab tawg cov hmoov, roj thiab khoom tawg yooj yim. Cov hmoov kub no feem ntau ntxiv los ntawm 10-15%, tom qab ntawd cov tuab tau ntxiv rau thiab sib tov tusyees, thiab thaum kawg cov tshuaj pleev ntxiv.
