Ski wax is a material applied to the bottom of skis or snowboards that will effect the performance of the ski in varying conditions. It can also be applied to other forms of snow transportation, such as toboggans. The two main types of wax used on skis are glide waxes and kick waxes. Glide wax is selected based on the temperature of the snow, and used to give skis the optimal amount of speed, no matter the conditions. Kick wax, for the classic style of cross-country skiing, is used to provide traction for kicking off the snow. == Glide wax == Glide wax can be applied to alpine skis, snowboards, skate skis, classic skis, back-country skis, and touring skis. Waxes, usually synthetic, can be hard or soft: * Harder waxes are for cold, dry, or abrasive conditions. Waxes can contain additives such as graphite, teflon, silicon, fluorocarbons, and molybdenum to improve glide and/or reduce dirt accumulation. The harder waxes typically are composed of longer molecules and tend to wear off the base faster than softer waxes.〔(【引用サイトリンク】url=https://www.skiwax.ca/tp/glide.php )〕 * Softer waxes are for warm or wet conditions. Softer waxes are typically composed of short and ring molecules. The hardness of the wax is controlled by the length of the carbon chains in the wax. Longer carbon chains create a harder wax while short carbon chains create softer waxes. A variety of glide waxes exists, each one optimized for a particular temperature range. Universal waxes, that span a wider range of temperatures, are also available. Glide wax can be rubbed on or applied by melting. * In hot waxing: wax is heated up against an iron, melted, and dripped onto the base of a ski and then ironed into the base. * Paste, liquid, spray-on, and rub-on waxes require no heating. * Hotboxing, consists of applying a wax with an iron, then warming skis in a device called a hotbox. Hotboxes open up the pores in the ski, this allows the recently applied wax to penetrate the base of the ski deeper and more effectively, creating an even faster gliding surface. * Infrared waxing uses infrared light to melt the wax. Some authors question necessity to use any glide waxes on modern ski base Other authors insist that the ski base material already has very good sliding properties and can only be improved by a small margin by glide waxes in defined snow conditions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ski wax」の詳細全文を読む スポンサード リンク
