freezing a certain amount of water at one time does not create
the surface that is used in ice rinks. It takes anywhere from
12,000 to 15,000 gallons of water layered in at least twelve
stages to make an ice surface suitable for a professional hockey
indoor ice should be one inch thick. A thick surface is too
soft and slows skaters down as they skate across the ice. Thin
ice is dangerous because skaters could penetrate the surface
and cut through the ice.
first two layers of water are sprayed on in a mist, each of
which is approximately 1/30th of an inch thick. The second
frozen layer is painted white so that the black hockey puck
will be easily seen on the ice. The third layer of water is
then sprayed on, which is 1/16th of an inch thick. After the
paint is sealed in underneath the third layer, the hockey markings
are added, including the lines, creases, and face-off circles.
The final layer (or layers) is then applied after all markings
and related logos are painted on the surface. The remaining
10,000 gallons are sprayed on gradually with a hose.
ice is created by the same technology that is used in refrigerators
and air conditioners. Instead of cooling ice directly, however,
the refrigerant cools brine water – a calcium-chloride
solution – that is pumped through pipes that are embedded
in the concrete floor underneath the ice. Beneath the pipes
and ice-bearing concrete slab is a layer of insulation, a heated
layer of concrete, and a sand and gravel base. A ground water
drain is located at the bottom of the sand and gravel base,
in the event that the rink needs to be drained.
ice resurfacing machines are used to maintain a high quality
of indoor ice before, during, and after ice hockey games. As
the Zamboni moves across the rink, the machine's blade shaves
the ice to produce a smooth surface. The shavings are then
collected and discarded into a snow tank inside of the machine.
The ice is immediately washed with water and a squeegee conditioner,
and finally clean hot water is spread onto the ice surface
with a towel.
many of today's large sporting complexes are used for different
sports, activities, and events, indoor ice, when not in use,
can be covered with insulation, and a different surface can
be placed on top of the ice. One such insulation, Homasote
Ice Deck, is a moisture-resistant structural panel that can
be placed directly over indoor ice for temporary conversion
of an ice rink for other activities. Homasote Ice Deck is manufactured
by the Homasote Company of West Trenton, New Jersey.
