Snow-melting agent
 

instruction for use:
After mechanical snow removal, the road is sprinkled with charcoal slag, coarse sand, branches slag and other substances to prevent slip, but also use the dark color of these slag substances to absorb the heat of the sun, to increase the ground temperature to melt the snow.After use, charcoal and tree branches can be put into the green land beside the road, without pollution.For roads that really need it, use a snowplow to remove most of the snow from the ground and then apply a small amount of it to prevent the road from freezing.And take advantage of ground heat, radiant heat from the sun and the heat emitted by cars themselves to help melt snow on the roads.
