Formate snow-melting agent is one of the organic snow-melting agents.

Formate snow-melting agent is one of the organic snow-melting agents. It is a de-icing agent that uses formate as the main component and adds a variety of additives. Corrosivity is significantly different from chloride. According to GB / T23851-2009 road de-icing and snow-melting agent (national standard), the corrosion of steel by FY-01 snow-melting agent and chloride salt was tested. 20 # carbon steel test pieces were continuously immersed in the de-icing agent solution at 40 ° C. 48 hours, test results (Table 2)

ITEM Stell corrosion rate(mm/a)
Speciciation Test Result Result
formic salt 0.1 0.02 Stell in formic salt solutins for 48 hours, keep news
Cl 0.11 Stell in Cl solutions for 48hours ,show much Fe, corrosion rate heavy,

The corrosion of cement concrete by the snow melting agent on the pavement is a key point of its performance evaluation. The following chart 3 is a comparison chart drawn by testing several concrete deicing agents on the pavement cement concrete according to the American standard SHRP H205-8 test method. This test method is an international universal method developed by the “Strategic Highway Research Program” (SHRP). Through this chart, it can be found that the corrosion rate of cement by sodium (potassium) and sodium acetate is only 1/3 of that of sodium chloride. And potassium acetate is slightly higher than sodium chloride.

tttt

The formate snow melting agent is a snow melting agent with the main component and other additives, which meets all the requirements of the US SAE-AMS-1431D.
