Description
Ice and snow melts, and ice-melt snow removing effect is remarkable, and the scope of application is extensive, and the preparation method is easy, compliance with environmental protection requirements.
One, technical field
Belong to chemical category, be the composite salt technical field.
Two, background technology
1, to inventing the understanding of " ice and snow melts "
Ice and snow melts and present employed snow-melting agent, no matter is solid-state or liquid state, all is in order to reduce the freezing point effect of water.Its snow melting mechanism belongs to chemical category, is the composite salt technical field.It utilizes the water-absorbent that ice and snow melts and a large amount of heat releases when melting, and makes the structural lattice dislocation in the snow, causes ice dissolution; Absorb heat during ice dissolution, surrounding temperature is descended, at this moment the vapour pressure of solution in order to reach new balance, impels ice and snow constantly to melt and form solution less than the vapour pressure of ice and snow, thus the zero pour of reduction water.Under cold condition, the above-mentioned compound movement equilibrium process that goes round and begins again is exactly the working mechanism of the ice and snow melting ice and snow of melting.Ice and snow melts, and in the process of development, not only pays attention to the use range and the effect of its ice-melt snow removing, and emphasis solves domestic present employed snow-melting agent, to problems such as the corrosion of metal and cement concrete and harm plant-growths.The present invention can reduce the corrosion to metal and cement concrete effectively, promotes the growth of plants such as flower, grass, trees, preserves the ecological environment, and has higher use value; Simultaneously the glassware for drinking water after the ice dissolution is had that bleaching delignification is black, deodorant to taste, sterilization and disinfection, purifies water and clean multinomial function such as road surface; Its scope of application is extensive and technical scheme is simple and easy to do.
2, ice and snow melts selected main raw material
It is by three kinds, four kinds, five kinds, six kinds, seven kinds in the industrial chemicals such as water and nitrocalcite, calcium chloride, magnesium chloride, sodium-chlor, clorox, aluminum chloride, sodium peroxide with as at least two kinds and water quality stabilizer---the PTX-CS in the industrial chemicals such as the Starso of inhibiter, Sodium orthomolybdate, Sodium Nitrite, tripoly phosphate sodium STPP, benzotriazole (BTA), Sodium Benzoate, form multiple best complex prescription by attribute separately, through optimizing composite refining forming.
3, the scope of application of the present invention extensively and ice-melt snow removing effect remarkable
Ice and snow melts and is irregular, polygonal solid granular of 0.1mm～8mm or liquid, and the attribute that it has low eutectic point is suitable for using under the state of temperature more than-33 ℃.It mainly is applicable to the ice-melt snow removing of northern area town and country different kinds of roads, motorway, airport, square, garden and bridge, is suitable for extensive mechanize and sheds or spraying operation.
Three, summary of the invention
1, the purpose of invention " ice and snow melts "
For solving domestic present employed snow-melting agent, snow removing speed is slow, be not suitable for using at a lower temperature, and solve it to problems such as the corrosion of metal and cement concrete and harm plant and greenery patches growths, preserve the ecological environment, improve the speed of ice-melt snow removing, make it be suitable under (33 ℃) above state of temperature, using; It can in time dredge snow back road, reduces because the sliding pedestrian's tumble injury that is caused in the road that black ice accumulated snow causes and the generation of all kinds of traffic accidents ensure normally travelling of various vehicles; Reduce a large amount of fortune snow that removes and work, and can save great amount of manpower and material resources and financial resources, create good social benefit and environmental benefit; Safeguard that city appearance environment is clean and tidy,, establish the overall image in city for citizen build comfortable live and work environment.The invention provides a kind of ice and snow melts.
