1. How to choose the size of the Ski board

Skiboard is one of the necessary equipment in skiing. Choosing the right Ski board size is important for improving the Ski experience and safety. So how do you choose the size of the Ski board?

1. Consider height and weight

The size of the Ski board is usually related to the height and weight of the individual.Generally speaking, the size of the Ski board increases with the increase of height.In addition, weight is also an important factor, because heavier people need wider and thicker Ski boards to provide sufficient stability.You can refer to the following suggestions:

(1) 150-160 cm height and 40-60 kg of weight: Skiboards with a selection length of 130-140 cm and a width of 70-80 cm.

(2) 160-170 cm height, weighing 60-80 kg: Skiboards with a selection length of 140-150 cm and a width of 80-90 cm.

(3) 170-180 cm height and 80-100 kg of weight: Slender boards with a length of 150-160 cm and a width of 90-100 cm.

(4) board of height of more than 180 cm and weighs more than 100 kg: Skiboards with a selection of more than 160 cm or more and a width of more than 100 cm.

2. Consider the technical level

Skirs of different technologies have different demand for skiing boards.Beginners usually need short and wider skiing boards to facilitate control and maintain balance; and experienced Ski people need longer and narrower skiing boards to improve the speed and flexibility.

3. Try to slip

If possible, it is best to try it before buying a Ski board.Test skating allows you to experience the size, weight and comfort of the skiing board in person, so as to better determine whether it is suitable for you.In addition, you can consult professional Ski coaches or clerks, and they will give appropriate suggestions based on your situation.

In addition, it should be noted that if you want to install fixed device, anti -collision bar and other accessories on the skiing board, you must consider that these accessories and modifications may affect the size and performance of the Ski board.

Second, the Skiboard is better or shorter or shorter

Skiboards have a variety of different lengths, and different lengths have a direct impact on skiing experience and skills:

1. In terms of stability

The longer skiing board provides better stability, suitable for the fast -ramp.The shorter Ski board is easier to control, suitable for beginners and skirs who are declining at low speeds.

2. In terms of turning radius

The longer radius radius of the Ski board requires more space and time to complete a curve.The shorter Ski board has a smaller radius, which is more suitable for gliding on a small slope.

3. In terms of gliding speed

The longer skiing board can provide higher gliding speed, suitable for senior skirs.The shorter Ski board is easier to control speed, suitable for beginners and low -speed slippers.

4. Technical performance

Skiboards of different lengths need different techniques to control.The longer skilets require more strength and skills to complete control and turning.The shorter Ski board is easier to control and turn.

In summary, the length of the Ski board is not fixed, usually determined according to height and weight, and comprehensively considers the skill level and Ski venue.

1, Artificial Vork Revisive:

Within six to eight weeks after paving, we need to clean the Artificial lawn every week, sweep the gravel to ensure that the straw stems are upright and gravel. The purpose is to maintain the height of the gravel18to20Millimeter level.Snow in Yuetian immediately stepped on, and the surface of the surface was scanned before using it.Artificial lawn should be used after use3arrive6Rinse with water for a month to keep its original color, so that quartz sand can be appropriately settled, and the lawn stabilizes the lawn.

2Foreign objects in artificial lawns:

Leaf, pine needles, nuts, gum, etc. can cause tangled, spots and stains, especially before exercise.This kind of foreign body should be avoided by the damage to artificial lawns.

3, Artificial Capture Water Seepage:

It is necessary to prevent external sewage from penetrating into the lawn and rushing to foreign objects.A circle of border stones (roads) on the edge of the lawn can prevent sewage from penetrating.

4precautions for the use of Artificial lawn venues:

The Artificial lawn sports field is only used for physical education and athlete training competitions. It is not allowed to do other purposes. You must wear professional sports shoes in the field.Bringing cigarettes, fire types, bubble sugar, organic solvents, and chemicals are processed into the field.Prohibit7mmLong nail shoes run on the lawn; prohibit any motor vehicles from driving on the lawn; forbid heavy objects to be placed on the lawn for a long time; prohibit the boundaries of the edge of the Artificial lawn by intentionally;Go on.

How to maintain Artificial lawn

1. Cooling

When the summer climate is cool, the surface temperature of the Artificial lawn is relatively high. It does not absorb calories to reach the cooling effect like natural grass. After all, the Artificial lawn isPEPolyethylene material, after high temperature exposure, the Artificial lawn will add thermal effects. In such a high temperature environment, it is easy to play with the physical discomfort in the athletes and then reduce the quality and interest of the competition.Therefore, the surface temperature of the decline of Artificial lawn is an important process of summer protection. Now it will generally decrease the temperature by watering the venue. This method is currently more useful.The professional league competition will be watered to the place before the premises to reduce the surface temperature.But the spray must be uniform and not too much, just spray the scene to moist.

2. clean

Various wastes will inevitably occur in football venues. Whether it is Artificial lawn or a place where natural lawns is needed, it needs to be cleaned. If it is simply floating and dust, natural rainwater can be cleaned.However, there are also many plastic waste, paper dandruff, peel and other waste demand for finishing and cleaning.Therefore, the protection operation of football places is necessary to include regular cleaning content.

Three, drainage

summer is also a dry season, and generally the dry season will gather4-10Between the month, especially the dry season in the South China region, there are many climate, so that it has a great impact on the drainage system of the Artificial lawn. Generally, small and small rain has no significant impact on the Artificial lawn place.When the lawn is built, a drainage system is made, and there is a small drainage hole on the back of the lawn. Generally, small and medium rain will not affect the Artificial lawn. Basically, the accumulation of water in the place can basically be discharged.However, there are often heavy rainstorms in the summer, so that the rainfall of the large lawn is not so fast, so that the lawn will be swallowed by floods, rubber particles and quartz sand are washed away, resulting in severe damage to the lawn of the venue.Therefore, the summer Artificial lawn protection drainage is essential.

Four, dehumidification

We all know that the air humidity in summer is relatively large, especially in the south, and the relative humidity is often very high.PECommonly known as plastic, fiber is very simple to reproduce and reproduce algae in the environment with relatively large humidity. If the algae category will become very slippery, it will simply make the athletes fall in the movement of the movement.So how to dehumidify has become a major problem for many builders.Decar dehumidification is also an important thing for summer Artificial lawn protection!
