[0010] In order to solve the snow removal agent currently used in China, the snow removal speed is slow, and it is not suitable for use at lower temperatures, and to solve its corrosion on metal and cement concrete, and to endanger the growth of plants and green spaces, protect the ecological environment, and improve ice melting and snow removal. The speed makes it suitable for use at a temperature above (-33°C); it can clear the road after snow in time, and reduce the occurrence of pedestrian falls and various traffic accidents caused by road slippery caused by hard ice and snow , to ensure the normal driving of various vehicles; reduce a lot of snow removal labor, and save a lot of manpower, material and financial resources, create good social and environmental benefits; maintain a clean and tidy city environment, and create a comfortable life and work for citizens Environment, establish the overall image of the city

Embodiment 1
[0053] Under the natural conditions of the highest temperature of -26°C, the lowest temperature of -33°C, and snowfall of 1.6mm; 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. The technical formula is: The weight content of each component is: (1=100kg / consumption)
[0057] The above-mentioned materials are put into the pulverizer in batches according to the weight of the components, and they are crushed and screened to make them reach the quality standard of 0.1mm ~ 8mm solid particles; Stir to mix all the materials evenly; finally, put the products that meet the quality standards into the spreading vehicle, and carry out the spreading operation on the implementation site, or pack the products that meet the ...
Embodiment 2
[0059] Under the natural conditions of the highest temperature of -16°C, the lowest temperature of -23°C, and snowfall of 1.3mm; 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. The technical formula is: The weight content of each component is: (1=100kg / consumption)
[0064] First put the water in the reaction kettle, then place the above-mentioned materials in parts by weight, put them in the reaction kettle in batches, stir for ≥30 minutes, and then add the water quality stabilizer——PTX-CS to the solution In the process, stir for ≥10 minutes, let stand for ≥30 minutes, filter out the residue with a 120-mesh copper sieve, make liquid ice and snow melt, spray on the im...

Abstract
This invention belongs to chemical category, it is complex salt field. It is consisted by water, calcium nitrate, calcium chloride, magnesium chloride, sodium chloride, sodium hypochlorite, aluminum chlorate, sodium peroxide and other chemical materials, and odium metasilicate, sodium molybdate, sodium nitrate, sodium tripolyhosphate, benzapyrene three nitrogen azole, sodium benzoate, water quality stabilizer-PTX-CS used as corrosion inhibitor. They are compounded by their attribution; there are solid and liquid states. Its sleet melting and snow removing velocity is quickly, environmental capability is good, and it can efficiently reduce the corruption to metal and cement concrete. Plant growth can be boost, and deodorization, bactericidin, purification water quality, pavement cleaning and other function can be realized to water after cleaning of ice and snow. It can be used widely above -400C, and for protecting city communication through, reducing traffic accident, and ensuring human body and auto safety, it has good effect. Is it fit for city and country road, freeway, airport, plaza, court and bridge.
Description
[0001] The ice and snow melting method 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. 1. Technical field [0002] The invention belongs to the chemical category and belongs to the technical field of compound salts. 2. Background technology [0003] 1. Understanding of the invention of "melting ice and snow" [0004] Ice and snow melting and currently used deicing agents, whether solid or liquid, are all for lowering the freezing point of water. The snow melting mechanism belongs to the chemical category and belongs to the technical field of compound salts. It uses the water absorption of melting ice and snow and the large amount of heat released during melting to displace the structural lattice in the snow, resulting in melting of ice and snow; when the melting of ice and snow absorbs heat, the surrounding temperature drops. At this time, the v...
