Description
Technical field
The invention discloses a kind of preparation method without chlorine composite environmental-friendly Snow Agent, belongs to Snow Agent preparing technical field.
Background technology
The snowfall and icing in winter often brings inconvenience to city and communications and transportation, and easily causes traffic accident, especially
It is on a highway, it is more likely that because of accumulated snow or make highway be forced closing freezing and stop transport, cause greatly economic damage
Lose.The mode of at present deicing snow melt mainly has artificial snow removing, snow removal with machine, spread Snow Agent removes the snow these three, wherein spreading Snow Agent
Due to being widely used the advantages of method is simple, easily operated, Snow-melting speed is fast.
The use of Snow Agent substantially reduces the inconvenience that Winter Snow is that people produce and life brings, but because tradition is melted
Snow agent irreversible harm that environment is caused and force numerous researchers progressively carry out the research of New Kind of Solvent of Snow-melted with
Exploitation.The development trend of Snow Agent develops from traditional single chloride salt Snow Agent to multicomponent organic Snow Agent.Current state
Inside and outside usage amount it is maximum be chloride salt Snow Agent be also the most permanent Snow Agent of usage history, current usage amount still accounts for 90%
More than, including sodium chloride, calcium chloride, magnesium chloride etc..
However, villaumite makes the mankind have to as the decades application of Snow Agent bears the negative work that such Snow Agent is brought
With because the chloride ion content in Snow Agent is too high, generally the anion of principal goods material is entirely chlorion, causes snow melt
The a large amount of chlorion road pavements on road surface are remained in afterwards produces corrosion, the use quality of heavy damage road and service life, and
Snow Agent solubility is larger, dissolution velocity is too fast, causes that Snow Agent action time is shorter, usage amount is excessive, unit bodies after effect
Snow Agent excessive concentration in accumulated snow water, soil is easily caused so as to produce excessive accumulation in soil around and underground water is dirty
Dye.In recent years organic Snow Agent engendered, but because its expensive starting materials, snow melt effect are preferable not as traditional Snow Agent, led
Cause its use range also less.Therefore, preferably the environment-friendly snowmelt agent of chloride ion-containing does not have to develop a kind of snow melt effect
Have broad application prospects.
The content of the invention
Present invention mainly solves technical problem：It is high for chloride ion content in existing Snow Agent, can satisfy the need after use
Corrosion is caused in face, and solubility is larger, dissolution velocity is too fast, causes Snow Agent action time shorter, while increasing usage amount
The defect of soil and underground water pollution can also be caused, there is provided one kind prepares environmental protection using calcium nitrate and modified Chinese medicine dreg
The method of Snow Agent, charing, acidleach after the present invention first crushes Chinese medicine dreg must be modified Chinese medicine dreg, then take wheat and carry out liquid
Saccharified liquid is obtained after change, saccharification, and saccharified liquid is prepared into into fermentation medium, inoculation yeast bacterium and acetic acid bacteria carry out fermented and cultured,
Obtaining add egg shell to carry out heating response after zymotic fluid sterilizing, can generate the zymotic fluid rich in calcium nitrate, last and Chinese medicine dreg
Carry out mixing and absorption, you can obtain without chlorine composite environmental-friendly Snow Agent, the present invention is rich in nitric acid using modified Chinese medicine dreg absorption
The zymotic fluid of calcium, makes snow melt long action time, while have the advantages that freezing point is low, Rateof snowmelt is high, and to metal, concrete and
Bituminous paving is almost corrosion-free, to plant non-hazardous, has broad application prospects.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）500～700g Chinese medicine dregs are weighed, in being put into baking oven, 8～10h, powder after being dried is dried at a temperature of 70～80 DEG C
