Cov kab mob hauv cov ntaub ntawv luam tawm
Cov tshuaj solvent xws li ethanol, isopropanol, butanol, propanol, methyl ethyl ketone, ethyl acetate, butyl acetate, toluene, thiab xylene feem ntau siv luam ntawv phais. Txawm hais tias feem ntau cov organic solvents yuav muab tshem tawm tom qab ziab, qhov seem seem tseem ua rau tib neeg lub cev.
