Description
Technical field
The invention belongs to sports apparatus field, be specifically related to a kind of hydrophobicity skis with drag-reducing abrasion-resisting effect.
Background technology
Skis base is the orlop part of skis, is also the part contacted with snow face.The hope that base that can quickly slide is every Ski amateur can be obtained.The base that current most of skises use is all that plastic material is made.Plastic material base can be generally divided into two classes: a class is melted and moulded;Another kind of is squash type.Melting that to mould the skis made be first then plastic melt is being cut into the shape of skis, melt plastotype skis long service life, it is easy to maintenance, but it is the slowest to melt the skis speed moulded, the amount of waxing is minimum.Squash type skis with melt plastotype skis contrast, plastics are first pulverized by squash type skis, excision forming again after then heating, compacting.Squash type skis compared to melt plastotype skis more solid, faster, wax, but squash type skis expensive, should not keep in repair.
Skis with the process of ground snow deposit relative motion in can produce violent friction, cause the abrasion of skis base.One secondary skis will lose its arch form curve after a long time use and straighten (it is inflexible to be generally known as).The arch form structure of skis is like the bow of hunter, if being placed on snow by skis, wrench and plate tail can land and the middle part of plate is unsettled.When athlete pushes down snow slab when revolution, strength is accumulated by snow slab just as bow, athlete just pushes next revolution when earth pressure release time, produces the effect of resilience.When the time length of skis will lose the ability of this resilience, skis is also eliminated.Skis also can come in contact with rock or other skis in motor process, also results in the abrasion of skis under such circumstances.When being seriously damaged at the bottom of plate, soft boards supporting substrates material is often marked very long groove by rock, also results in fractureing of skis when serious.
Skis is with the contact process of snow face, and skis susceptor surface can produce water membrane, and the interaction force between moisture film and skis base hampers the quick mobile of skis.Therefore the moistening degree that the translational speed of skis is necessary for reducing moisture film to skis base is improved, namely want liquid at the contact angle of skis base, contact angle is more little, and reaction liquid is more good to the wettability of the surface of solids, and the resistance of skis rapid movement is more big.Otherwise, contact angle is more big, it was shown that the hydrophobicity of the surface of solids is more good, and skis is easier to obtain quick motion.
The major way of present stage skis drag-reducing abrasion-resisting is to be coated with ski wax at skis base.Ski wax can make skis base have relatively low coefficient of friction with snow mask, reduces frictional force, improves the movement velocity of skis.Ski wax can also reduce the abrasion condition of skis planing surface, and the snow wax on bottom surface contacts with snow face, and the abrasion of snow wax instead of the abrasion of skis base itself.
But the ski wax spreading upon skis susceptor surface can, by snow deposit wearing away quickly, need constantly repeatedly wax, bothersome effort.And owing to wax layer surface is also hydrophilic surface, the moisture film being adsorbed on wax layer surface can quickly condense into ice sheet, the problem producing to be stained with snow.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention proposes a kind of hydrophobicity skis with drag-reducing abrasion-resisting effect, this skis is by imitating the hydrophobicity non-smooth structure of lotus leaf surface, hydrophobicity and the wearability of skis can be effectively improved, reduce the frictional resistance of skis and snow face, the skis life-span can be extended and without repeatedly waxing.
The technical solution adopted in the present invention is:
A kind of hydrophobicity skis with drag-reducing abrasion-resisting effect, described skis susceptor surface makes the cell cube of the hemispherical or semielliptical shape projection of regular layout by Laser Processing or compressing technique, and cell cube is in the rectangular distribution of skis susceptor surface.
