Cov poov tshuaj tsim muaj txiaj ntsig sib piv

Cov poov tshuaj formate, cov ntsev ua kua ntsev, muaj ntau dua li lwm yam kab mob de-icing xws li:

  • Poov tshuaj acetate
  • Urea
  • Glycerol

Piv nrog rau cov tshuaj poov tshuaj formate, noj ntawm tus kwv tij cov txiaj ntsig ntawm 100%, cov neeg ua haujlwm potassium acetate muaj qhov ua tau zoo tsuas yog 80 txog 85%, nyob ntawm qhov ntsuas kub.

Qhov no piv rau kev ua kom tau zoo li ntawm 70% rau urea thiab 45% rau glycerol.
