Embodiment 1

[0018] This embodiment provides a kind of artificial snow for laying ski tracks, which is prepared by the following method:

[0019] Will D 90 200g of 100μm sodium chloride crystals, immersed in an aqueous solution containing 0.1% sodium carboxymethyl cellulose and 0.2% glycerin by mass percentage, first stand for 10 minutes, ultrasonically treat for 5 minutes, then stand for 10 minutes, and filter out the crystals , dried at 60°C for 50 minutes, fully mixed the dried crystals with 2.5 g of water fluffy granular sodium polyacrylate (after absorbing 40 ml of water and then mixed with the crystals) to obtain the product.

Embodiment 2

[0021] This embodiment provides a kind of artificial snow for laying ski tracks, which is prepared by the following method:

[0022] Will D 90 Submerge 200 g of sodium chloride crystals with a diameter of 120 μm in an aqueous solution containing 0.08% sodium carboxymethylcellulose and 0.4% glycerin by mass percentage, first let stand for 10 minutes, ultrasonically treat for 5 minutes, then let stand for 10 minutes, and filter out the crystals. Dry at 60°C for 50 minutes, fully mix the dried crystals with water fluffy granule PET 4g (after absorbing 40ml of water and then mix with the crystals) to obtain the product.

Embodiment 3

[0024] This embodiment provides a kind of artificial snow for laying ski tracks, which is prepared by the following method:

[0025] Will D 90 Submerge 200g of 80 μm sodium chloride crystals in an aqueous solution containing 0.3% sodium carboxymethyl cellulose and 0.2% glycerin by mass percentage, let it stand for 10 minutes, ultrasonically treat it for 5 minutes, then let it stand for 10 minutes, and filter out the crystals. Dry at 60°C for 50 minutes, fully mix the dried crystals with 4g of water fluffy PET particles (after absorbing 30ml of water and then mix with the crystals) to obtain the product.

Abstract

The invention relates to a method for preparing artificial snow for paving ski tracks. In the method, inorganic salt particles are immersed in a polymer aqueous solution with a concentration of 0.01% to 1% by mass, fully stirred or ultrasonically treated, and the crystals are collected by filtration. The crystals are dried and mixed with water fluffy particles at a mass ratio of 10-400:1 to obtain the product. The raw materials of the method provided by the invention are easy to obtain, the steps are simple, and the prepared artificial snow has a small friction coefficient and a fast sliding speed, so that the friction on the skateboard is small, which can bring a good skiing experience, and has good water retention performance and long service life. , has a good market application prospect.

Description

technical field [0001] The invention relates to the field of artificial snow, in particular to artificial snow for laying ski tracks and a preparation method thereof. Background technique [0002] With the development of the times, skiing has been widely carried out all over the world. The significance of skiing is not only in sports, but also a healthy and fashionable way of life. As an outdoor sport, skiing is the biggest The charm lies in allowing people to experience the feeling of returning to nature during sports. However, due to its particularity, factors such as seasons, regions, temperatures, and venues have very large restrictions on skiing. The current artificial snow condenses water vapor into ice flowers by cooling down, which consumes a lot of energy and is expensive, which is not conducive to widespread development. Skiing in the world basically belongs to people with relatively free wealth and time. The purpose of the present invention is to overcome the de...
