FIELD: heating systems. ^ SUBSTANCE: invention refers to manufacture of artificial ice and can be used in sports and construction industry when building artificial ice rinks, skating tracks, etc. Artificial ice manufacturing method involves freezing of at least one layer which contains additions of water suspension of polytetrafluoroethylene and/or copolymer of tetrafluoroethylene with hexafluoropropylene and/or perfluorodecalin. At least one layer is frozen by being filled with water which contains addition of water suspension of polytetrafluoroethylene and/or copolymer of tetrafluoroethylene with hexafluoropropylene and/or perfluorodecalin, which passed vacuum low-temperature removal of chemical compounds deteriorating ice surface smoothness. ^ EFFECT: increasing elasticity and sliding properties of ice surface of artificial ice covering owing to pre-cleaning of suspensions of additions, removal of chemical compounds deteriorating ice surface smoothness (vacuum cleaning). ^ 4 ex, 6 cl |
