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
The present invention relates to the preparation of a kind of ice-melt or snow melt high water activity reacting metal material, belong to the deicing technical field.
Background technology
Road freezes and to be meant precipitation, like rain, snow, sleet, or droplet, runs into that temperature is lower than the ground of zero degree and the accumulated snow or the icing phenomenon that occur.Generally include the hard ice sheet of the road ponding of the residual snow that freezes, concavo-convex ice rut, snowmelt or other reason in formation in season in severe winter.Road freezes and to be divided into two kinds of situation: a kind of is to be frozen in immediately after the snowfall to form road on the road surface and freeze; Another kind is behind snow melting, forms on the road surface because temperature reduces and freezes, and be the important chief culprit of traffic hazard.When the appearance road freezes, because wheel and pavement friction effect weaken greatly, skid easily, the incessantly car of stopping causes traffic hazard.The pedestrian also slides into easily, causes tumble injury.At the beginning of 2008; Tens provinces, China south continue to occur sleet, freezing weather, cause many motorways because of the icing first rear enclosed of road accumulated snow, and the Civil Aviation Airport freezes and closes because of airstrip, a large amount of accumulated snow in hardstand; Personnel's goods and materials can't transport, and traffic have been caused seriously influence.
Metal and water reaction discharge great amount of heat, and as shown in table 1, its reaction product is MOX and hydrogen.Yet owing to the restriction of oxidation on metal surface layer, metal and water existence reaction start slowly, react lasting difficulty, the low inferior shortcoming of reaction efficiency in practical application.Problem to above-mentioned proposition; The present invention through high-energy ball milling method adopt variable speed repeatedly the round-robin ball-milling technology prepared high water activity reacting metal material; This active material can start the rapid reaction with water at low temperatures, discharges great amount of heat, product environmental protection again; Harmless to road, therefore this water reacting metal active material is used as efficient ice-melt/snow agent.
