COMPOSITION AND METHOD FOR SURFACE LAYER OF ICE MASSIF PREPARING TO RUN SPEED SKATING COMPETITIONS AND TRAINING |
摘要 |
FIELD: adaptation of ice surface for speed skating competitions and training, particularly indoor skating rinks. ^ SUBSTANCE: ice surface creation method involves preparing ice massif for following ice layers forming; performing prepared ice machine massif shipping through 0.35 mm depth in single operation; spraying purified water at temperature of 40°-75°C onto prepared surface to freeze the first ice layer; performing machine spraying of purified water-based composition at temperature of 40°-75°C and freezing of the second and at least one next layer during previous ice layer shipping, wherein the water-based composition includes polyethylene glycol solution and ammonia spirit with 0.00002-0.0002 % by weight of polyethylene glycol and 0.0005-0.003 % by weight of ammonia spirit; holding each of said layers for time selected from time interval between 20 min and 2 hours at temperature of heat carrier in ice massif base plate pipes equal to -9°C/ -14°C. Composition for ice surface preparation comprises polyethylene glycol solution with 0.00002-0.0002 % by weight of polyethylene glycol and 0.0005-0.003 % by weight of ammonia spirit, remainder is water. ^ EFFECT: increased ice surface slipperiness. ^ 8 cl, 3 dwg |
