Flame Retardant
OLH-ZRJ
Flame retardants do not affect other properties of asphalt mixtures, but are highly effective in flame retardancy and smoke suppression. They are also energy-saving, environmentally friendly, and reduce carbon emissions. They are suitable for tunnel asphalt pavement projects.
Add the weighed flame retardant to the asphalt storage tank or asphalt mixing tank, and stir it at a temperature of 165°C-190°C for 30min-40min until it is mixed with the asphalt.
To prevent segregation, it is recommended to use freshly prepared.
