Abstract
A snow composition is here provided which comprises of about 100 parts by weight of snow selected from the group comprising of natural snow, artificial snow made by a snow machine, and icy snow made by shattering ice blocks to fragments and about 0.1 to about 10.0 parts by weight of a super absorbent polymer in granule form having an average particle size of about 20 to about 500 .mu.m before water absorption. A method for making artificial snow is also provided here.
Claims16
A snow composition which comprises
- (1) about 100 parts by weight of snow selected from the group consisting of natural snow, artificial snow made by a snow machine, and icy snow made by shattering ice blocks to fragments and
- (2) about 0.1 to about 10.0 parts by weight of a super absorbent polymer in granule form having an average particle size of about 20 to about 500 .mu.m before water absorption.
A method for making artificial snow comprising the steps of
- (a) spreading a dried or partly wet super absorbent polymer in granule form having an average particle size of about 20 to about 500 .mu.m before water absorption onto a snow covering made from snow selected from the group consisting of natural snow, artificial snow made by a snow machine, and icy snow made by shattering ice blocks to fragments,
- (b) making a mixture by blending the polymer with snow in a mixer, and then
- (c) freezing said mixture.
A method for making artifical snow comprising the steps of:
- (a) mixing a super absorbent polymer in granule form having an average particle size of about 20 to about 500 .mu.m before water absorption with water to absorb less water than its upper limit of water absorbability,
- (b) making a mixture by blending said water swollen super absorbent polymer in granule form with snow selected from the group consisting of natural snow, artificial snow made by a snow machine, and icy snow made by shattering ice blocks to fragments, and then
- (c) freezing said mixture.
