Embodiment 1

[0059] It is used when the minimum temperature is above -26°C, and the external environment is: highways, urban and rural roads, viaducts, overpasses, docks, traffic roads covered with ice and snow, and when motor vehicles are driving intensively. Its technical formula is components by weight: (1=100kg / consumption)

[0060]

[0061] In the purchase of calcium chloride, magnesium chloride and sodium chloride, calcium chloride and magnesium chloride produced in Golmud area of ​​Qinghai Province and sodium chloride produced in Wuhai area of ​​Inner Mongolia should be selected. The sulfate ion SO 4 2— The content is extremely low, and then the method of adding corrosion inhibitors can effectively reduce the corrosion of steel bars and concrete for viaducts, overpasses, platform bridges, tunnel bridges, tunnels, expressways, and urban and rural roads in reinforced concrete structures. The combination of calcium chloride, magnesium chloride, sodium chloride and calcium nitrite i...

The combination of calcium chloride, magnesium chloride, sodium chloride and calcium nitrite in this technical...

Embodiment 3

[0069] It is used when the minimum temperature is above -30°C, and the external environment is: expressways, urban and rural roads, viaducts and overpasses, the road surface is covered with ice and snow, and the motor vehicles are driving intensively. Its technical formula is components by weight: (1=100kg / consumption)

[0070]

[0071] In the purchase of calcium chloride and sodium chloride, calcium chloride produced in Golmud area of ​​Qinghai Province and sodium chloride produced in Wuhai area of ​​Inner Mongolia should be selected. The sulfate ion SO 4 2— The content is extremely low, and then the method of adding corrosion inhibitors can effectively reduce the corrosion of steel bars and concrete for viaducts, overpasses, platform bridges, tunnel bridges, tunnels, expressways, and urban and rural roads in reinforced concrete structures. The combination of calcium chloride, sodium chloride and calcium nitrite in this technical formula can slow down the thermal shock of...

Abstract

The invention discloses a snow melting agent, and belongs to the technical field of composite salt. Water and one, two, three, four, or five of calcium chloride, magnesium chloride, potassium chloride, sodium chloride, calcium nitrite, calcium hypochlorite, and urea chemical raw materials, a a water quality stabilizer, one, two, three, four, or five of sodium citrate, sodium hexametaphosphate, sodium gluconate, polyaspartic acid and other chemical materials as a corrosion inhibitor, one, two, three, four, or five of chemical fertilizers for promoting plant growth, potassium fulvate for improving a soil aggregate structure, and sodium chloride and activator urea for alleviating pavement thermal shock are used for forming the snow melting agent according to respective attributes. The snow melting speed is high, the use amount is small, and the effect is good; both solid and liquid exist and the snow melting agent can be used at the temperature of over 35 DEG C; corrosion to metal and concrete can be effectively reduced; the plant growth is promoted; the snow melting agent has functions of bleaching, sterilization, disinfection, skid resistance, road surface cleaning and the like on water obtained after ice and snow melting; the snow melting agent, is suitable for mechanical throwing or spraying operation.

Description

[0001] The invention is a deicing agent, which has remarkable effects of melting ice and snow, has a wide range of applications, is easy to use, and meets environmental protection requirements. [0002] 1. Technical field [0003] The invention belongs to the chemical category and belongs to the technical field of compound salts. [0004] 2. Background technology [0005] l. Understanding of the invention of "a deicing agent" [0006] The present invention and the currently used deicing agent, whether solid or liquid, are all for lowering the freezing point of water. Its ice-melting and snow-removing mechanism belongs to the category of chemistry and belongs to the field of compound salt technology. It makes use of the water absorption of the deicing agent and the large amount of heat released during melting to displace the structural lattice in the snow and cause the ice and snow to melt. When the ice and snow melt, they absorb heat and lower the surrounding temperature. At...
