Dab tsi yog De-Agent icing?

De-icing agent yog ib yam tshuaj uas siv los txo qhov kub ntawm cov dej khov thiab daus. Nws cov khoom xyaw tseem ceeb suav nrog sodium chloride, calcium chloride, magnesium chloride, thiab lwm yam. De-icing agent dissolves hauv dej daus kom txo qhov dej khov ntawm cov dej daus, ua kom yooj yim yaj. Common de-icing agents suav nrog cov hauv qab no:

Organic de-icing tus neeg sawv cev: Nrog cov poov tshuaj acetate ua cov khoom xyaw tseem ceeb, nws muaj cov nyhuv snow melting zoo thiab tsis tshua muaj corrosion, tab sis tus nqi kuj siab. Nws yog tsim rau tshav dav hlau, golf, thiab lwm yam.
​Chloride de-icing tus neeg sawv cev: suav nrog sodium chloride, calcium chloride, magnesium chloride, thiab lwm yam, tus nqi kuj qis, tab sis nws yuav ua rau muaj kev xeb rau txoj kev thiab txuas hniav.
