Nyob hauv tsev, koj yuav tau tos txog 7-8 teev. Yog hais tias feem yog ua cov txheej txheem, tom qab ntawd nqa cov metallization tsuas yog ib hnub tom qab dhau los.
Kauj ruam 3
Siv cov tshuaj tsuag phom tshwj xeeb los yaug cov khoom nrog dej distilled. Tom qab ntawd, siv cov tshuaj tshwj xeeb rau lub disc, hauv cov reductants thiab chromium yog sib xyaw, thiab yaug dua.
