Title:
ARTIFICIAL COLD SNOW
Document Type and Number:
Japanese Patent JP2017176834
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide artificial cold snow that can efficiently simulate natural snow properties and can easily be produced and used, and greatly reduces restriction to skiing due to environmental temperature and season, and thereby can greatly improve the profit of a skiing ground, and provide a production method.SOLUTION: Artificial cold snow comprises artificial cold snow particles containing solid particles having magnetism. Residual magnetism of the solid particles is in a range of 1,000-9,000 gauss. Materials capable of changing the surface quality are deposited on the surface of the solid particles. A high polymer material layer or a metal plated layer are deposited on the surface of the solid particles. Also, a production method comprises: a step of crushing magnetic materials into the solid particles by a crushing device (1); a step of sorting the solid particles by a predetermined particle size using a sieve and depositing the material layer capable of changing the surface quality on the surfaces of the solid particles after the sorting; and a step of magnetizing the solid particles after the sorting (3).SELECTED DRAWING: Figure 3
