Structure and characteristics of snowboards
Generally divided into alpine board, cross-country biathlon board, platform board, freestyle board, veneer and so on. Alpine slab is composed of multi-layer structure, mainly including elastic material resistance, box structure compared with previous years, slab core, glass fiber composite material, polymer bottom plate, metal edge and so on.
The snowboard base is the lower part of the snowboard and the part that touches the snow surface. Most bases are made of plastic materials. One of these two kinds of bases is molten plastic and the other is extrusion molding. Molten plastic is melted first and then cut. They have long service life and are easy to maintain. But the speed of melting snowboards is the slowest, and the amount of waxing is the least.
Squeezing skis is just the opposite. They are ground into powder, heated, pressed and cut into various shapes. Compression plate is better, stronger, faster and better than wax on solute plate.
Another kind of graphite board, graphite board is the fastest of all snowboards, and it has a lot of wax. The graphite substrate is polyethylene, and graphite is added into plastic particles, and then made into plates. Such boards are generally dark black, and all you can see in speed skating competitions are graphite boards.
Arched head, the slightly inclined part of a skateboard. The size of arch is closely related to its flexibility. The higher the arch, the greater the head and tail pressure of the board. The very flat arch head shows that the steering of this board is very flexible, so it is suitable for some freestyle sports. For a used board, a flat head also means that the board has been used for too long.
For most new skis, choosing a slightly curved arch head can help you turn flexibly in high-speed skiing, even in hard snow.
Contacts, these points have direct contact with snow, but do not bear the pressure of human body. These points are also called base wheels. Usually near the head and tail. If you put the snowboard on a smooth surface, put a piece of paper under it and drag it, it will be very smooth and easy to drag in the center until you touch these points, and the paper will stop.
Edge, this refers to the metal edge of the snowboard. The front is called toe margin, and the back is called heel margin.
Effective blade, the part of the snowboard blade that contacts the snow is the part that works when turning, which is called effective blade. Excluding the front and rear edges of the head. When making a big turn, the effective blade will touch the snow. The longer and more stable the effective edge is, the easier it is to control the sliding. Although the effective edge is short, the steering is flexible.
A bending point, usually at the junction of two plates. This usually happens at the beginning or end of a round. Let the skateboard touch the secant of the snow extension radius. Hard twist points can control ice and snow well. On the other hand, a softer board can make the board more stable and suitable for beginners.
