Method for preparing high-activity water-reactive metal material for melting ice or snow

Abstract

The invention relates to a method for preparing a high-activity water-reactive metal material for melting ice or snow, and belongs to the technical field of ice removal. The method comprises the following steps of: mixing metal powder, a catalyst and inorganic salt; setting ball-milling parameters of a ball mill, namely setting a ball-to-material ratio, a ball-milling rotate speed, cycle times, ball-milling time and the like; and putting the mixed materials and a mill ball into the ball mill, milling and combining according to a set ball-milling process to obtain a metal material, and scattering the metal material on the surface of frozen ice or frozen snow uniformly, wherein the active material reacts and releases heat, and the ice and the snow are melted with the reaction of the active material on the surface of the frozen ice or the frozen snow, are separated from the bottom and are melted completely. In the method, the high-activity water-reactive metal material is prepared by a high-energy ball-milling process, and the active material reacts on the surface of the frozen ice or the frozen snow quickly and releases the heat, and has an obvious effect on the quick melting of the frozen ice or the frozen snow.

Description

technical field [0001] The invention relates to the preparation of a highly active water-reactive metal material for melting ice or snow, and belongs to the technical field of deicing. Background technique [0002] Road icing refers to precipitation, such as rain, snow, freezing rain, or fog droplets, when it hits the ground with a temperature below zero and the phenomenon of snow accumulation or icing occurs. It usually includes frozen residual snow, concave and convex ice ruts, snowmelt water or other reasons for road water to form a hard ice layer in the cold winter season. Road icing can be divided into two situations: one is that the road icing is formed immediately after snow falls; culprit. When the road is icy, because the friction between the wheels and the road surface is greatly weakened, it is easy to slip, and the car cannot be braked, resulting in traffic accidents. Pedestrians are also prone to slipping and causing falls. At the beginning of 2008, rain, sn...

When the road is icy, because the friction between the wheels and the road surface is greatly weakened, it is easy to slip and the car cannot be braked, resulting in traffic accidents

Pedestrians are also easy to slip and cause falls

At the beginning of 2008, rain, snow and freezing weather continued to occur in more than a dozen provinces in southern my country, resulting in the closure of many highways due to snow on the roads. transportation, which has a serious impact on traffic

However, in practical applications, due to the limitation of the oxide layer on the metal surface, there are disadvantages such as slow start of the reaction between metal and water, difficulty in continuing the reaction, and low reaction efficiency.
