Abstract
Method is applied in combination the invention provides a kind of liquid anti-ice-snow material and its with " the consolidating after first liquid " of solid ice-melt snow material.This kind of application method be:Before snowfall is arrived or when just starting, to road surface spraying liquid anti-ice-snow material, the material has to be not easy to slide to curb when dispensing, it is not easy quickly to be lost in because ice and snow solution dilutes, can be produced on road surface separation layer to prevent stagnant ice snow be bonded on road surface, and will not road pavement cause corrosion the advantages of.After there is accumulated snow or icing phenomenon, then dispense solid ice-melt snow material.Two kinds of materials are used in combination, as soon as liquid anti-ice-snow material usage is solid ice-melt avenge material ten/, directly can avenge material for solid ice-melt and enough humidity is provided, and can produce to act synergistically and reach the effect of more preferable melting ice and snow.Wherein, liquid anti-ice-snow material by mass percentage consisting of:Freezing point depressing agent 20%~65%, carbohydrate 1%~10%, water 27%~79%.
Description
Technical field
The present invention relates to a kind of method that is applied in combination of snow melting material, this method is specifically related to a kind of liquid anti-ice-snow material
Exploitation and its method is applied in combination with solid ice-melt snow material.
Background technology
The winter accumulated snow on road surface freezes and has a strong impact on the safety of people, and usual snow removing method has three kinds:(1) resist
Snow and ice climbing, i.e., prevent snow and ice in road surface freezing by the method for chemistry;(2) snow removal with machine operation, that is, big machinery is utilized
Equipment removes accumulated snow from road surface;(3) melt snow and ice climbing, i.e., the accumulated snow being frozen on road surface is carried out by the method for chemistry clear
Remove.
Three of the above method respectively has advantage and disadvantage, and (1) anti-ice-snow material is usually using solid salt either salt at present
The aqueous solution, it is easy to use, but the simple aqueous solution using salt is as anti-ice-snow material, because it is playing a role
The ice and snow rapid dilution that can be melted simultaneously, in the case of a large amount of uses, when pavement temperature is higher than the freezing point of solution, it can make
Into the quick loss of anti-ice-snow material, when pavement temperature is less than the freezing point of solution, the solution after dilution is easy to freeze again
Cheng Bing, cause bigger road traffic hidden danger.(2) snow removal with machine due to efficiency it is low, it is icy on road after it is not easy to operate wait limitation, more
More is to need to coordinate snow melting material to be used together the adhesion that effectively could be reduced or eliminate between ice sheet and road surface.(3) it is single
Solid Snow Agent solely is used, is that Snow Agent particle spherical during shedding easily slides to curb first, causes the inequality dispensed
The waste of uniform Snow Agent, and the burden of increase environment.Secondly, solid Snow Agent needs to dissolve and could send out after environment moisture absorption
The effect of its deicing or snow melting is waved, it is longer to play efficacy window.Simultaneously as the spreading of solid Snow Agent is to snow or freezing
Carry out later, penetrate thicker ice sheet, melting the ice sheet combined with road surface needs the longer time.
In addition, use chief destructive to caused by environment of traditional freeze proof deicing product be it to metal, concrete and
The corrosion of bituminous paving, so add which kind of corrosion inhibiter has turned into whole world exploitation high-efficiency environment friendly to reduce the corrosivity of deicer
The main target of type product, the research work that there is correlation the country are carried out, but still suffer from corrosion mitigating effect and owe preferable, high expensive, and
Addition is small to cause product to be difficult the problems such as being well mixed.
The content of the invention
The defects of present invention exists for prior art and application, there is provided a kind of liquid anti-ice-snow material, and propose one kind
The method of anti-ice snow removing is applied in combination in " solid after first liquid ".
Described liquid anti-ice-snow material, by mass percentage its specifically comprise:
Freezing point depressing agent 20%~65%
Carbohydrate 1%~10%
Water 27%~79%
Wherein:
Described freezing point depressing agent can be that sodium chloride, calcium chloride, magnesium chloride, potassium acetate, calcium acetate magnesium salt etc. are therein
It is one or more of.
Described carbohydrate can be monose, polysaccharide, cellulose and its derivates class, dietary fiber, xanthans, card
Draw the one or more therein such as glue.
Described " solid after first liquid " method of being applied in combination is:According to weather warning situation, open before snowfall is arrived or just
During the beginning, certain density liquid anti-ice-snow materials for later use first is prepared by quality composition, spraying operation, profit are carried out by watering device
With the amount of sprinkling sowing of linkage VFC liquid anti-ice-snow material, it is ensured that road surface is covered by liquid anti-ice-snow material, so on road surface
Upper generation is effectively isolated layer and is bonded in prevent stagnant ice snow on road surface.Appearance icing is further reduced when there is accumulated snow or temperature now
As rear, then the ice-melt of solid high-efficiency corrosion inhibition type is dispensed by truck spreader and avenges material, it is specific dispense dosage according to snowfall size (slight snow,
Middle school, heavy snow etc.) it is adjusted.
Material is avenged in described solid high-efficiency corrosion inhibition type ice-melt, and it is specifically comprised by mass percentage:
Freezing point depressing agent 95%~98%
Corrosion inhibiter 0.5%~4%
Water 1%~2%
Wherein:
Described freezing point depressing agent can be that sodium chloride, calcium chloride, magnesium chloride, potassium acetate, calcium acetate magnesium salt etc. are therein
It is one or more of.
Described corrosion inhibiter can be imidazoles, sodium gluconate, sodium dihydrogen phosphate, nine silicate hydrate disodiums, sodium molybdate
Etc. one or more therein.
Beneficial effect:
(1) fluid present invention anti-ice-snow material has good rust inhibition and adhesiveness, will not road pavement cause to corrode, delay
It is preferable to lose effect, is not easy during spreading to slide to curb, can be kept for the longer residence time, be not easy because ice and snow solution is dilute on road surface
Release and be quickly lost in, effectively ice and snow can be prevented to be bonded on road surface.The material has with solid ice-melt snow material and cooperateed with simultaneously
Effect, it just can be good at promoting the deicing or snow melting ability of solid ice-melt snow material in the case where dosage is seldom;
(2) liquid anti-ice-snow material is first sprayed, then broadcasts sowing solid ice-melt snow material again, the method being applied in combination can increase
The effect of strong anti-ice deicing, is greatly decreased the usage amount of solid Snow Agent, and reduces because the use of anti-snow and ice material is to gold
Corrosion and destruction etc. caused by category and road surface.
(3) the solid ice-melt snow material being used in combination, deicing or snow melting ability is strong, due to the liquid anti-ice-snow material first sprayed
Humidity can not only be provided for its dissolving, meanwhile, the ice sheet not being frozen in directly on road surface is easier to be worn by solid ice-melt snow material
Thoroughly, be advantageous to it and faster play deicing or snow melting effect.
