If it absorbs water and freezes it, it can be made into artificial belt to make artificial snow like powder snow, so that the superabsorbent polymer can be frozen below the water absorption capacity. In the case of artificial snow, < water-absorbent loose powder snow-like artificial snow is produced. The material used for the formation of the bottom layer 12 in the present invention is large and the price of heat storage energy is more suitable as ice, but it can also be used. The materials for forming the lower layer 12 include the above-mentioned superabsorbents. . The superabsorbent polymer can absorb a large amount of water with a high heat storage capacity, and when it rises, it will not disappear like snow, and it can be continuously and effectively used. Water-retentive superabsorbent polymer prevents snow from melting when the temperature rises because it absorbs a large amount of water, accumulates heat, and has good heat insulation properties ^ Γΐί: Raw polymer can maintain its preservation even if the temperature rises; the bottom layer 1 2 Sustainable use.

The gas insulation is higher, making it 卩 六 | U use. It makes Ba snow better in preventing snow melting, so it can be properly used.

Also from the viewpoint of economics, the amount of ancient people ^ _ L is appropriately used to make dii: reduce the amount of super absorbent polymer or more. Asked that the water absorption capacity of the water-based I compound is 5. When using superabsorbent polymer in the state of pine t particles, Yu will fly away, and the artificial snow will flow out of the X groove 18 when it melts. In order to prevent the occurrence of sexual polymer in this special situation, the lettuce fires silicon. Into the bamboo ancestors, the same water absorption asks that the water-soluble polymer does not leak to the outside, and the perforated water-permeable packaging (the main and outer parts of the weaving fabric are reported to the outside — y ^ Non-fiber cloth mesh cloth, porous sheet and other materials (such as soil sack bag, mesh cloth bag, rice bag, grass deer bag, etc.), 、, pore hole sheet bag, cooling layer 11 is better ) Packed and set most of them on silk, etc .: K constitution can be plastic such as polyolefin or polyester, or special plastic of steel; natural fibers such as reed and cotton, etc. Cheaper and more suitable for use. When using or recovering the eyes, the technology of π A 14 t a is at the time of laying and makes the water polymerize = = government or outflow. When using a water-permeable packaging body with a highly absorbent κ mouthpiece inside, it can effectively maintain the stability of the bottom layer 12 and when recycling:!

And biodegradation without accumulation will be described about the method of using the insert to form the lower layer 12. It is a high-quality material suitable for environmental protection. The water-permeable polymer of the super absorbent polymer is packaged on the cooling layer 11 so that the inner packages are adjacent to each other, and a plurality of fixtures are laid at the same time. f. The water-permeable polymer with a super absorbent polymer is inserted, and the water-permeable packaging body is also fixed, for example, after the auxiliary body is fixed. Then, water is supplied internally so that the water-absorbent polymer is not water, and The water-absorbent package containing the water absorbent with a capacity lower than the water absorption capacity is stored inside the water-permeable packaging body ^ J and the water is laid on the aforementioned lower layer 12 with artificial snow (manufactured by artificial snow machines such as fan, fan type, and fan type 4). Artificial snow or artificial ice) and artificial snow layer 8. Due to temperature rise, the amount of artificial snow layer 8 when it melts snow ^ can be absorbed by the super absorbent polymer in the lower layer 12 so that Xialudi can be used as the base layer snow and the snow quality of the artificial snow layer 8 can be maintained well. The present invention is not limited to the above-mentioned embodiments, and can be modified in various ways without departing from the spirit and scope described in the scope of patent application for invention patents.
