Embodiment 1

[0050] Under the natural conditions of the highest temperature of -8°C, the lowest temperature of -13°C, and snowfall of 0.9mm; the external environment is: the downtown area, the greening is good, the road is covered with ice and snow, and the motor vehicles are driving intensively. Be: sodium chloride, trisodium phosphate and calcium hypochlorite, sodium molybdate, trisodium phosphate, sodium metasilicate, sodium tetraborate and sodium benzoate; the weight content of each component is: (1=100kg / dosage)

[0051] Sodium Chloride: 80 Trisodium Phosphate Chloride: 1.5

[0052] Calcium hypochlorite: 1.5 Sodium molybdate: 5

[0053] Trisodium Phosphate: 5 Sodium Metasilicate: 2

[0054] Sodium tetraborate 2 Sodium benzoate 3

[0055] The above-mentioned materials are put into the pulverizer in batches according to the weight of the components, and are crushed and screened to make it reach the quality standard of 0.1mm ~ 8mm solid particles; Stir to mix all the materials evenl...

Embodiment 2

[0057] The highest temperature is +33°C, the lowest temperature is +26°C, and the natural conditions are dry; the external environment is: the downtown area, dense motor vehicles, good greening, and the road surface is polluted and needs to be cleaned. The technical formula combination is: Water, sodium chloride, chlorinated trisodium phosphate, bleaching powder, sodium metasilicate, benzotriazole, lithium hypochlorite and polyaluminum chloride; the weight content of each component is: (1=100kg / Dosage)

[0058] Water: 95 Sodium Chloride: 30

[0059] Trisodium chlorinated phosphate: 1 Bleaching powder: 1.3

Abstract

The present invention belongs to field of compounded salt technology. It is made up by respectively adding at least three kinds of chemical raw materials of chlorinated trisodium phosphate, calcium hypochlorite or high test bleaching powder, aluminium chloride or aluminium polychloride, lithium hypochlorite, sodium sulfate peroxide, sodium meta silicate, sodium molybdate, sodium benzoate, trisodium phosphate, sodium tetraborate or medicinal borax and benzotriazole, etc. Its the formula composition formed from water and sodium chloride through a certain preparation process. Said invention has two kinds of solid product and liquid product, and can be used when the temperature is above-21 deg.C, its ice-melting and snow-removing speed is quick and its effect is good.

Description

[0001] The deicing agent has remarkable effects of melting ice and snow, has a wide range of applications, has a simple and convenient preparation method, and meets environmental protection requirements. [0002] 1. Technical field: It belongs to the category of chemistry and belongs to the technical field of compound salt. 2. Background technology [0003] 1. Understanding of the invention of "a deicing agent" [0004] A deicing agent and currently used deicing agents, whether in solid state or liquid state, are all for lowering the freezing point of water. The working mechanism of the deicing agent belongs to the category of surface chemistry and belongs to the technical field of compound salts. It uses the water absorption of a deicing agent and the large amount of heat released when it melts to displace the structural lattice in the snow, causing the ice and snow to melt; when the ice and snow melt, it absorbs heat and reduces the surrounding temperature. At this time, the...
