Abstract
The ice and snow melting agent is produced by mixing proper amount of glycol, propanediol, propanetriol and isopropanol being liquid at normal temperature with water. It has a solidifying point of minus 87 deg.C and may contain certain amount of acetone for increased permeation effect glycol, propanediol, propanetriol and acetone used are produced from starch. The ice and snow melting agent is spread directly to the surface of ice and snow in the amount of 80-200 g/sqm each cm of thickness. The liquid mixture after melting has very low solidifying point and volatilizes or perneates into ground without re-freezing. The ice and snow melting agent has no pollution to environment.
Description
The present invention relates to a kind ofization ice and snow material and using method thereof (C09K3/00).
Usually use sodium-chlor or auxiliaryization of glycerine ice and snow, its cardinal principle is to reduce and the mixed apparent freezing point of ice and snow, in changing the ice and snow process, dissolving or dilution heat release, in order to improve usefulness, only considering under the prerequisite of economic and practical, by the zero pour of reductionizations ice and snow material to greatest extent, with the apparent freezing point of reduction mixture; Or change ice crystal structure is beneficial to physics or chemical process is eliminated, and also requirement can not pollute environment simultaneously, and vegetation is damaged.Relevant technologies mainly contains two pieces in the disclosed patent application, the first disclosed publication number on June 26th, 1996 is CN1125247A, name is called the application for a patent for invention of " snow-removing and ice-thawing agent ", provide a kind of by producing the byproduct calcium chloride of alkali and the fontanel powder that major ingredient is magnesium chloride with seawater and Wingdale, major ingredient is that the salt quarrel of sodium-chlor is sub through the mixed material that gets of high temperature, its two be on November 29th, 1989 disclosed publication number be CN1037530A, name is called the application for a patent for invention of " antifreezer for water-bearing particles and compound method thereof ", provide a kind of moisture coal or breeze of can making under-40 ℃ of temperature conditions, to change the ice crystal structure, Diethylene Glycol by 10-40%, the ethylene glycol of 10-25%, the amine carbonate of 15-35%, the material that the surface-active substance of 0.1-0.6% is mixed with, it is low inadequately that these materials exist zero pour, the phenomenon of easily freezing once more after the snow melting also exists the defective of contaminate environment simultaneously.
Goal of the invention of the present invention is to propose substantially no longer to freeze after a kind of use and to the free of contamination substantially snow melting ice of environment material.
The present invention seeks to realize by such measure: main by an amount of ethylene glycol, propylene glycol, glycerol, Virahol and water are formed, ethylene glycol wherein, propylene glycol and glycerol are made by starch.
Goal of the invention of the present invention also is to propose a kind of using method of snow melting ice material.
The present invention seeks to realize by such measure: directly spray in the ice and snow surface without dilution, every cm thick ice and snow amount of application is 80-200g/ square metre.
Below the present invention is further described by implementing side.
Ice and snow melting agent of the present invention mainly is by an amount of ethylene glycol that is in a liquid state at normal temperatures, propylene glycol, glycerol, Virahol and water make through mixing and stirring, and zero pour can reach-87 ℃, also can add amount of acetone as required, to increase osmotic effect, ethylene glycol wherein, propylene glycol, glycerol and acetone are made by starch.
The present invention is applicable to temperature in the time of 0 ℃～-15 ℃, and component is 35% ethylene glycol, 15% propylene glycol, and 25% glycerol, surplus are Virahol and water.Snow melting thickness is 5-15cm, and the snow melting time is 10-35 second; Changing the ice thickness degree is 1-3cm, changes 3～5 minutes ice time.Every cm thick ice and snow amount of application is 80-110g/ square metre.
The present invention is applicable to that temperature is at 0 ℃--in the time of 25 ℃, component is 35% ethylene glycol, and 10% propylene glycol, 30% glycerol, surplus are Virahol and water.Snow melting thickness is 10-20cm, and the snow melting time is 35-60 second; Changing the ice thickness degree is 3.8cm, changes 10-40 minute ice time.Every cm thick ice and snow amount of application is 100-140g/ square metre.
The present invention is applicable to that temperature is at 0 ℃--in the time of 35 ℃, component is 35% ethylene glycol, and 25% glycerol, 20% acetone, surplus is propylene glycol, Virahol and water.Snow melting thickness is 20-35cm, and the snow melting time is 1-2 minute; Changing the ice thickness degree is 8-10cm, changes 40-50 minute ice time.Every cm thick ice and snow amount of application is 120-160g/ square metre.
The present invention is applicable to that temperature is at 0 ℃--in the time of 45 ℃, component is 30% ethylene glycol, and 10% propylene glycol, 20% glycerol, surplus are acetone, Virahol and water.Snow melting thickness is 20-45cm, and the snow melting time is 1.5-2.5 minute; Changing the ice thickness degree is 8-13cm, changes 60-90 minute ice time.Every cm thick ice and snow amount of application is 140-200g/ square metre.
After the present invention uses, it is very fast to change ice and snow speed, because it is very low with the mixed apparent freezing point of icy water that melts, most of mixture volatilizees in the air or infiltrates through ground, basically no longer icing, it is lower to change the ice and snow cost, simultaneously since the raw material basic source in starchy material, substantially nontoxic, can not pollute environment.
