Problems solved by technology

Although the purpose of snow removal is achieved, it is highly corrosive, which will not only cause serious corrosion to roads, bridges, motor vehicles and traffic road facilities, reduce the service life, but also cause damage to flowers and trees on both sides of the road, and cause salinization of the soil , causing environmental pollution; and the existing snow-melting powder can only remove the snow on the surface of the railway turnout, and it is difficult to completely remove the snow on the side wall

Embodiment 1

[0015] A snow melting agent for railway turnouts, which is made of the following raw materials by weight: 25~35 parts by weight of potassium acetate, 3~6 potassium nitrate, 5~10 magnesium acetate tetrahydrate, 5~10 calcium nitrate tetrahydrate, and 5~ammonium dihydrogen phosphate 10. Urea 1-5, sodium molybdate 3-8, sodium formate 25-30, sodium metasilicate 0.2-1.0, ethylene glycol 15-20 and glycerol 10-15.

[0016] The method for preparing snow melting agent for railway switch, the specific steps are as follows: a. Combine the potassium acetate, potassium nitrate, magnesium acetate tetrahydrate, calcium nitrate tetrahydrate, ammonium dihydrogen phosphate, urea, sodium molybdate, sodium formate and partial Sodium silicate was crushed and passed through a 20-mesh sieve, and then the formula was weighed and mixed to obtain mixed powder A; b. According to the formula, stir and mix ethylene glycol and glycerol to obtain mixed liquid B; c. Add the mixed powder A to the mixed liquid B a...

Embodiment 2

[0018] A snow melting agent for railway turnouts, which is made of the following parts by weight of raw materials: potassium acetate 26, potassium nitrate 4, magnesium acetate tetrahydrate 6, calcium nitrate tetrahydrate 8, ammonium dihydrogen phosphate 6, urea 3, sodium molybdate 3, Sodium formate 29, sodium metasilicate 0.4, ethylene glycol 17, and glycerol 14.

Abstract

The invention relates to a snow melting agent for a railway turnout. The snow melting agent is prepared from the following raw materials in parts by weight: 25-35 parts of potassium acetate, 3-6 parts of potassium nitrate, 5-10 parts of magnesium acetate tetrahydrate, 5-10 parts of calcium nitrate tetrahydrate, 5-10 parts of ammonium dihydrogen phosphate, 1-5 parts of urea, 3-8 parts of sodium molybdate, 25-30 parts of sodium formate, 0.2-1.0 part of sodium metasilicate, 15-20 parts of ethylene glycol and 10-15 parts of glycerin. The snow melting agent for a railway turnout provided by the invention can be used for thoroughly clearing snow on the side wall of the railway turnout and is harmless to soil while the cost is low and the snow melting effect is good.

Description

technical field [0001] The invention belongs to the technical field of deicing agents, and in particular relates to a deicing agent for railway turnouts and a preparation method thereof. Background technique [0002] As the running speed and density of railway passenger trains continue to increase, the punctuality requirements are getting higher and higher. It is required that the turnouts should be switched normally in snowy weather to ensure the normal operation of trains. At present, the winter turnout snow removal work in northern my country adopts the method of manual cleaning, which is labor-intensive, time-consuming, inefficient and has hidden dangers to personal safety. Density operation requirements. At the same time, according to the overall requirements of the railway, the turnouts of the passenger dedicated lines north of the Yangtze River in my country will be equipped with turnout snow melting equipment to ensure the normal use of passenger dedicated lines. . ...
