Tus neeg sawv cev ua kom daus yaj yog ib qho ntawm cov neeg sawv cev ua kom daus yaj. Nws yog tus neeg sawv cev de-icing uas siv formate ua cov khoom tseem ceeb thiab ntxiv ntau yam khoom ntxiv. Kev xeb yog qhov txawv ntawm chloride. Raws li GB / T23851-2009 txoj kev de-icing thiab tus neeg sawv cev yaj daus (tus qauv hauv tebchaws), kev xeb ntawm cov hlau los ntawm FY-01 tus neeg sawv cev yaj daus thiab ntsev chloride tau raug sim. 20 # carbon steel daim ntawv xeem tau raug muab tso rau hauv cov tshuaj de-icing ntawm 40 ° C. 48 teev, cov txiaj ntsig xeem (Rooj 2)

Qhov xeb ntawm cov cement los ntawm cov neeg sawv cev yaj daus ntawm txoj kev yog qhov tseem ceeb ntawm nws qhov kev ntsuam xyuas kev ua tau zoo. Daim ntawv qhia hauv qab no 3 yog daim ntawv sib piv kos los ntawm kev sim ntau tus neeg sawv cev deicing ntawm cov cement cement raws li tus qauv Asmeskas SHRP H205-8 txoj kev xeem. Txoj kev xeem no yog txoj kev thoob ntiaj teb thoob ntiaj teb tsim los ntawm "Strategic Highway Research Program" (SHRP). Los ntawm daim ntawv qhia no, nws tuaj yeem pom tias qhov xeb ntawm cement los ntawm sodium (potassium) thiab sodium acetate tsuas yog 1/3 ntawm qhov ntawm sodium chloride. Thiab potassium acetate siab dua li sodium chloride me ntsis.
Tus neeg sawv cev yaj daus yog tus neeg sawv cev yaj daus nrog cov khoom tseem ceeb thiab lwm yam khoom ntxiv, uas ua tau raws li txhua qhov yuav tsum tau ua ntawm US SAE-AMS-1431D.
