Description

Resin composition for artificial ice link {RESIN FOR ARTIFICIAL ICE SKATING RINK}

The present invention relates to a composition for artificial ice link, more specifically, the composition of the (1-1), (1-2) and (1-3), and (1-3) Permanent, stable and low abrasion suitable for skating by adding 2-1), (2-2) composition, (3-1), (3-2) composition, (4) composition and zinc oxide or titanium dioxide Its low water absorption, low surface friction, and high surface retention make it possible to skate regardless of season while having the same driving feeling as on natural ice.

Ice skating is one of the most enjoyed sports around the world. When doing this exercise on natural ice, either an appropriately sized outdoor or indoor link should be provided. The construction and management of outdoor links depends on moody weather and such links cannot be used in warm climates or in warm seasons. Indoor links using natural ice, on the other hand, must be equipped with a centralized cooling system to keep the ice surface at an appropriate temperature and to prevent the ice from melting. Ice skating rinks made of natural ice, whether outdoors or indoors, need to be resurfaced periodically to maintain a smooth ice surface and enough to skate. Such resurfacing usually consists of an expensive self-propelled ice surface retouching device, often referred to as a Zamboni device.

Artificial ice links have a number of advantages over natural ice links as shown in the following table.

division Natural Ice Link Artificial Ice Link  Constraints   There are many restrictions on the environment such as climate.   It is hardly affected by the environment such as climate, so it can be easily installed and used inside and outside.  maintain   Maintenance cost is high (I need ice management using jam bonnie)   Low maintenance costs.  link   Use is limited.   It can be used for multipurpose purposes.  Ice quality   Depending on the weather conditions, after about three hours the ice will fall below 80%.   80% to 90% retention for 10 years.  Mobility   It is fixed.   Regardless of place (free movement and installation possible)  Facility Management   Aging of equipment due to moisture and moisture.   Deterioration and delay of equipment due to lack of moisture and moisture.  revenue   Expensive maintenance fee.   Management cost and facility cost reduction effect.

As shown in the table above, the natural ice link is fixed and cannot be moved once installed, whereas the artificial ice link has the advantage that it can be easily installed at any place and is convenient to move and install as needed. I boast ice and its semi-permanent lifespan has advantages over existing ice rinks.

Natural ice links suffer from financial deficits due to huge investment costs and maintenance costs such as ice machines and electric bills. Artificial ice links maximize profits at a low cost because they rarely cost maintenance, maintenance and management. It is an economical product that solves the shortcomings of the natural ice rink that the ice does not freeze or the snow or rain is likely to be rough due to the disturbance.
