[Second -hand skiing board] How long is the service life of the skiing board talk about the purchase skills of second -hand skiing boards

1. Skiboards have a life span

Generally, the life span of the snowboard is 80-100 days, and the competition board is 40-60 days.Of course, this is just a reference value. The actuality is related to the weight force of the user and the taxi method.The same board was slipped by a girl with a weighing 45kg for 200 days. It may be better than a 90kg of a big man with a 90kg.After this life, the board is "dead". Of course, the dead board can still be slippery, but the elasticity of the board will greatly reduce, and the ability to engrav the hard snow will be significantly worse.

2. Why does the Ski board have a lifetime life

The life of the snowboard is mainly related to the repeated deformation of the board.With a firing with the wire repeatedly, you will find that it will soon lose its elasticity.The same is true for boards.

3. How to identify the life of the snowboard

3.1 If you have a piece of the same model to compare with it, put them all on the ground, and the arc (so -called Camber) arched up upward will be different.

A board maintains the capacity of Camber, it is related to the material of the core core and the enhanced material: the "foam" core is the worst. This kind of core core is filled in. Basically, there is no ability to maintain shape, and there is no flexibility itself;Big Muxin is better; the strongest is those who add metal reinforcement layers. Although these reinforcement layers have the original effect to make the board hard, not to extend their life, they will have the chairmanship.

3.2 In addition to Camber, there are also limited life span. It is the reason why the competition board has a short life. The core of the competition board will also be used, but their blade is the thinnest.

4. How to choose second -hand boards

First of all, the rental board does not need to be considered.Many places to rent boards sell boards every year, and the price may be very low, and they may have done certain maintenance for the board when they sell, making them better than the second -hand board on the private hands. Anyway, maintenance is for them anyway.The cost is very low.But in fact, the rental board may be able to serve for 80-100 days in a snow season, and the private hand can slip in the snow season for 20 days.Therefore, the life loss of the rental board for one year is equivalent to 3-5 years in private hands. If you count it, you will find that their so-called cheap price is actually not very cheap.It is an elimination product.

Secondly, the test slide can be considered, if you can see it.The skid board is generally a relatively new model. The purpose of the manufacturer's test skid is to promote and promote the new products. They often do not use it to eat dry and wipe out.It is impossible to test the slide one year a year, and the model of the trial slip the next year must be the new model of the next year.In some places, you can buy it directly and you can buy it directly.If you buy a test slide online, online stores generally explain how many times the board has slipped.

There is also the panel on the private hand. Look at the year, see it as color, and try not to buy too old.The buying that year would not be slipped many times.Of course there are exceptions, for example, the other party is an athlete.

5. How to look at the color of the board

Looking at the color of a piece of board, it mainly depends on the thickness of the blade.Because the bottom of the board can be repaired, and the plate surface is basically scarred as long as it slides a few times.Of course, Camber can also be seen before, but this thing is not gradient. It may suddenly become flat when it is about to die. During the period of elastic deformation, it is similar, so it is not reliable.

Looking at the thickness of the blade, it is best to know how thick the new one is, as a reference.The blade of the rental board is originally thicker than others. The blade of the competition board is relatively thin. These factors should also be considered.

1. winter sports shoes buy leather or mesh

In winter, if you choose a mesh on sports shoes, you will have a better breathability. Those who love sports, choose the mesh comfort, and it is easy to clean.If you choose a sports shoes with leather noodles, the warmth will be better, but the softness and comfort of the shoes may not be good.If the local winter is not particularly cold, you can choose the mesh.If the weather is cold, choose leather sneakers, so that the snowy days will also prevent the shoes from getting wet and not comfortable to soak their feet.

The mesh sneakers are light in texture, the overall quality of sneakers is relatively light, and wearing is relatively light.The mesh sneakers are divided into two types according to the different number of mesh. One is that the surface of the upper is only the surface of the surface, and the single -net sneakers with fabrics inside; the other is the surface and inside of the upperDouble -net sports shoes.

The overall appearance of the upper of the leather sneakers is made of leather, which contains fabrics.Leather sneakers are mainly divided into three types of leather materials, which are PU -made sneakers, sports shoes made of ultra -fine fiber, and natural leather sports shoes.Among them, the price of PU materials is relatively cheap, the price of super fine fiber sneakers is relatively high, and the price of leather sneakers is higher. Now leather sneakers are mostly PU fabrics.

2. The difference between breathability

The material of the mesh sneakers is mesh and has a lot of breathable holes, so it has good breathability, especially suitable for being worn in spring and summer.Dry.

Everyone who passes through the leather sneakers knows that the breathability is relatively poor, especially when sweaty feet are hot in the weather, wearing leather sneakers will be very smelly.However, leather sneakers have a good anti -wind and warm effect, and can be worn in cold days.

3. Differential wear resistance

Compared with mesh sneakers, leather sneakers are more strong and wear -resistant.However, the leather sneakers are more likely to have creases, and the creases of sneakers on the mesh surface are not obvious.

4. The difference between cleaning convenience

Compared with the mesh sneakers and leather sneakers, it is more troublesome to clean, and the mesh is relatively dirty. It takes some time when cleaning.The leather sneakers are more convenient to clean. After the upper is dirty, you only need to use a humid towel to wipe it clean. It is very convenient.

5. The difference between comfort

It was also sweaty to practice yoga. Therefore, the temperature of the indoor temperature controlled at about 20 can feel comfortable.After practicing for a short period of time, our bodies will heat up. The greater the strength of the practice, the more physical consumption, the hotter the body will be.When the body feels hot and can adapt to the surrounding environment, you can turn off the air conditioner or heating.

Choose the practice method of high temperature yoga

High-temperature yoga is a popular yoga type in winter. Because it is practiced in high temperature environments, it can play a role in keeping warm and cold.

What are the functions of Ski glasses

Ski mirrors are essential for skiing people. Because the sunlight reflection in the snow is very powerful, and the cold wind is very irritating to the eyes, it is very important to choose the appropriate Ski mirror.

Whether you are a master or a beginner, the right Ski mirror must have the following basic functions:

1. Anti -fog, mirroring fog will blur the sight of Ski people, and it is easy to accidentally accidentally.

2. Anti -ultraviolet rays, the sunlight reflection in the snow, strong ultraviolet rays will burn their eyes.

3. Wind -proof, whether you are skilled or not, the cold wind will stimulate the eyes when gliding.

4. It is best to be a double -layer resin. Even if it is impacted, it will not cause damage to the face.

5. There is a breathable mouth. The upper eaves of the outer frame are used with breathable mouths made of breathable sponges, so that the thermal air discharged from the facial Skin is spread out of the mirror, ensuring that the mirror has a good visual effect.

Which Ski mirror is good

The price of foreign brands is very expensive, and the price of foreign brands sold in China is very outrageous. The price of $ 170 abroad is sold to $ 290 in China. In addition to taxes, there are more profits of dealers.Most of the foreign brands are around 1700 yuan, and most of the domestic brands are below 200 yuan. It is suitable for snowfield tourists.

Buy suggestion:

1. Beautiful perspective, more or less consider matching the color of your favorite skiwear.

2. Quality first, no matter what, skiing is a dangerous movement. It must be the best selection within the scope of the price scope you can bear.

3. Although the snow mirror is a small part of skiing equipment, it also needs to be complete. You can carry a small cloth bag with a snow mirror with you.

4. It is highly recommended that the spherical mirror, the view of the spherical mirror is wider, and its impact resistance and anti -deformation ability greatly exceed the column surface lenses.

How to choose Ski mirror

1. enough strength

First of all, it is necessary to ensure that the Ski mirror is not easily broken by impact, and it is not easy to harm the eyes and faces.There is no thing that will not be damaged, even if it is steel, it is no exception, just to see the power and location of the impact.You know, it is the best snow mirror at present. The professional small rotary athletes with a large amount of training are also destroyed by the flagpole every year!Good snow mirrors do have better strength, stronger ability to absorb impacts, and lower probability of damage.This type of snow mirror requires high -quality frames, lenses, and glue. High -strength resin is the mainstream materials for making frames and lenses. From the current cost of production at home and abroad, snow mirrors with retail prices at more than 100 or even 100 are often still still more than 100 or even 100.It is difficult to guarantee the use of some ordinary or slightly enhanced plastic materials.Many wholesale markets selling glasses and Sunglasses also have similar Ski mirrors or wind mirrors, and the appearance is made of a whistle, but it is slightly twisted in my hand. The creak sound really makes people worry about whether this lens frame will be slightly impact.It will break, wound glasses and faces.

2. Good anti -fog ability

There is no difference between the Ski mirror wearing the fog.The anti -fog effect of the Ski mirror relies on three ways to achieve: the appropriate ventilation inside the snow mirror, the temperature difference between the inside and outside of the lens, and the anti -fog coating in the inside of the lens.The role of point 1 is to reduce the concentration of water steam in the snow mirror, but it will not cause them to condense into fog sharply; the latter 2 is that the warm air in the snow mirror is not easy to condense on the lens even if the humidity is very large, it is not easy to condense on the lensEssenceThe ventilation of the snow mirror is realized through the breathable sponge of the face and facial contact with the snow mirror. The key to ventilation is to reasonably control the size of the ventilation volume: to ensure that the inside warm and humid air in the snow mirror can be discharged as soon as possible through the sponge on the upper part of the snow mirror, and it will not use it to prevent it.The dry and cool outer air from the sponge under the snow mirror is too fast to enter the inside of the snow mirror to cause the lens to be cold, and the saturated water vapor in the snow mirror quickly encounters the cold condensation, thereby reducing the lens fog.To this end, some high -end snow mirrors also have a special ventilation regulatory system that can regulate and control the volume of ventilation.

3. Matching with the face shape

You must try to choose!In particular, the parts of the lower edge of the snow mirror should be in line with the facial and nose bridge, to prevent the water vapor of the mouth and nose from being mixed with the cold wind into the snow mirror, causing a severe mist.At the same time, prevent cold wind from blowing in and stimulating the eyes.Some of them can also try the matching of snow mirrors and helmets. Generally speaking, most snow mirrors and helmets can be worn with each other. There may be differences between the gaps between the snow mirror and the helmet.Asian and European and American models: White and yellow people have different faces, which are very different for snow mirror.European and American nose is high, and the style of mainstream snow mirrors is high in the middle. Most Asians wearing nose will leak wind, causing cold wind to blow their eyes and snow mirrors in a serious fog. For this reason, most candidates have improved Asian brands or European brands.Asian style is better.

4. High -definition

The lens is Smooth and Smooth, and the material of the lens is uniform and no impurities. Only in order to ensure that it is clear, no deformation, and the eyes of the eyes will not be fatigue.The problem lens hurts the vision.

5. Appropriate light transmission rate

It is the depth of the color of the lens that people usually say.Reduce the strong light of sunlight and snowfields to avoid snow blindness and eye fatigue.Those who often skate the night market or shade and snowy areas should be selected with light -colored lenses with light increase and brightening. Frequent dark lenses of the Yangxue Farm in the daytime, and various conditions are Smooth.There are also some discolored snow mirrors and glasses that can replace lenses, which can better adapt to different weather, morning and evening, and different directions.

6. Separate ultraviolet rays

Protect your eyes and prevent sunburn.The isolation rate of general professional snow mirror ultraviolet rays is above 99 %, so there is no need to worry about it.In fact, I personally think that this isolation rate of more than 90 % is no longer meaningful, and the sun is not harmless to others every day, unless it is engaged in welding or ultraviolet disinfection.

7. Ball and column

The spherical mirror has risen in recent years, and the mainstream was the column mirror before.The main differences and features of the two are:

(1) Visual error: In the level of glasses, the horizontal error of the left and right of the spherical mirror and column mirror is the same; but when the eyes look up and down, the vertical error of the column mirror is gradually increased than the vertical error of the spherical mirror.This is the players of the single board player and the dual -board medium slipfer and grind style (flying, air turning, rotation, steel pipes and U -shaped grooves). Because they often need to look up and down, they need more accurate control actions and falling points. They often choose to chooseThe reason for the spherical mirror; of course, the spherical mirror looks more public, and it is in line with this style.

(2) The sphere is relatively stable and more resistant to impact than the column surface structure.

(3) Because the head is an elliptical ball type with a long up and down, especially when wearing a helmet and column mirror at the same time, the overall front wind resistance of the head of the head is smaller, and the double -board racing players are basically maintaining the level at the slide. ThereforeAlmost all the double -board racing players choose almost all column mirrors.

(4) The same protrusion level, the space inside the column mirror is greater, so almost all the snow mirrors wearing myopia mirrors are almost designed.

In addition, after the spherical mirror with color or chrome -plated mirror coating, it is indeed more modern and more in line with the current aesthetic trend.

8. Double layer and single layer

Double -layer lens protection capabilities are stronger and the anti -fog ability is higher.Generally, the same snow mirror, the price difference between a single layer and double layer is 100-200 yuan.Individuals need to choose according to economic conditions.The double -layer lenses are also different. Some of the two -layer lenses are sealing, and some two layers of lenses are pasted with rubber or sponge pads around a circle.The former's anti -impact and anti -fog ability is better than the latter.Some say that the two -layer lenses are pumped into vacuum in the middle. I personally do not agree, because the thin and soft double -layer seal resin lens, if the middle is vacuum, the middle part of the two layers of lenses will be pressed together by the outside atmosphere.Or at least the trap, but the actual observation is not the case.Therefore, between the two -layer lenses, the air or nitrogen gas that removes the moisture should be filled, which not only prevents the fog, but also slows down the lens oxidation and aging.
