Abstract
The invention relates to an environmentally friendly snow melting agent which comprises the following components in percentage by weight: 90-110 percent of calcium chloride, 15-25 percent of urea, 15-25 percent of sodium nitrite, 10-15 percent of potassium sulphate, 22-30 percent of sodium metasilicate and 50-90 percent of carbon black. The environmentally friendly snow melting agent can be used for effectively solving the problems of the traditional snow melting agent used in China on corrosion to metal and cement concrete, damage to plant growth, and the like. The snow melting agent product does not contain sodium chloride, thereby reducing the influences and the damages to roads and environment of ordinary snow melting agents, and has the advantages of high snow melting speed, no corrosion, small feed dose, economy, environmental protection, and the like. Products after melting can be used for promoting the growth of plants, and compared with the traditional products, the snow melting agent has micro corrosion to the metal and the cement concrete and also has safety and reliability; the residual products after snow melting can be used for promoting the growth of the plants so as to realize reutilization; and the snow melting agent is easy to deliquesce, has certain effects of stabilizing soil and controlling dust and good flowability and is easy to scatter and mechanically spread.
Description
Technical field
The present invention relates to a kind of snow-melting agent, especially relate to a kind of novel environmental protection snow removing agent.
Background technology
The northeast of China, northwest, North China's winter climate cold, snowfall is more, and when snowfall, rainfall, ground is accumulated snow and icing very easily, and generally the employing and the mode that more effectively removes the snow mainly are snow removal with machine and chemical snow melt at present.Snow removal with machine has maneuverability, speed and soon, is not subjected to temperature restriction, characteristics such as applied widely, but has deficiencies such as Ex-all rate variance, fragile road surface. and chemistry removes the deficiency that snow dust can remedy snow removal with machine, is a kind of effectively anti-icing, deicing or snow melting means.The snow-melting agent of present common use belongs to the chloride salt snow-melting agent, comprises sodium-chlor, calcium chloride, magnesium chloride, Repone K etc., and a large amount of heat releases during by its water-absorbent and thawing make the structural lattice dislocation in the snow, cause ice dissolution.Absorb heat after the ice dissolution, temperature around making descends, at this moment the vapour pressure of solution is less than the vapour pressure of ice and snow, in order to reach new balance, impel ice and snow constantly to melt, form solution, thereby reduced the zero pour of water, under cold condition, the equilibrium process of above-mentioned compound movement carries out again and again, the melting ice and snow principle of snow-melting agent ice-melt that Here it is snow removing.But it is very serious to the corrosion of large-scale public infrastructure, and a large amount of uses can cause soil salt too high, cause a large amount of plant death, also can destroy a bridge etc. because of having constituted the galvanic corrosion metallic facility.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of environmental protection snow removing agent, and this snow-melting agent can not cause soil salt too high, can not corrode public infrastructure yet, is a kind of snow-melting agent of very environmental protection.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
Environmental protection snow removing agent, form by following weight ratio by following component:
Calcium chloride: urea: Sodium Nitrite: vitriolate of tartar: Starso: carbon black=90-110: 15-25: 15-25: 10-15: 22-30: 50-90.
Described environmental protection snow removing agent, form by following weight ratio by following component:
Calcium chloride: urea: Sodium Nitrite: vitriolate of tartar: Starso: carbon black=100: 20: 20: 12: 25: 70.
The method for preparing environmental protection snow removing agent, its making processes is:
Get in proportion and add entry behind the above-mentioned raw materials thorough mixing and make saturated solution solution and get final product.
The method for preparing environmental protection snow removing agent, the temperature of water are 60 ℃-80 ℃.
Advantage and effect that the present invention had are:
The snow-melting agent that environmental protection snow removing agent of the present invention can effectively solve domestic present use is to problems such as the corrosion of metal and cement concrete and harm plant-growths.Sodium chloride-containing not in the product has reduced influence and the destruction of common Snow Agent to road and environment.It is fast to have snow melt speed, does not have corrosion, and it is little to add dosage, advantages such as economic environmental protection, the product after the thawing can promote plant-growth, with traditional product relatively, small to the corrosion of metal and cement concrete, safe and reliable.The residual product of snow melt can promote plant production, realizes second stage employ; The easy deliquescence of this product, have certain stable soil, control dust effect.Good fluidity is easy to shed and mechanical spreading.
