Description

SNOW AND ICE MELTING COMPOSITION
FIELD OF THE INVENTION
The invention relates to production of snow and ice melting compositions that contain chemical salts: sodium and other chlorides as well as additional ingredients. Such a composition can be used for melting snow and ice on roads, streets, sidewalks, parking lots and other surfaces in winter.
BACKGROUND OF THE INVENTION
Ingredients for snow and ice melting compositions are usually stored separately and mixed immediately before applying onto the roads, otherwise reaction between constituent chemicals is likely. Such a reaction may result in the composition getting limp and packed during storage causing uneven application when being used. The most common ingredients used for this purpose are sodium chloride and abrasive substances: a mixture of sand or grit. However, such a snow and ice melting composition causes quite a lot of negative effects, leading to corrosion of vehicles, roads, concrete and metal structures and machinery as well as sidewalks. Moreover, salt and snow-ice solutions flow to roadsides, ditches and harm roadside vegetation.
Salts used in production of snow and ice melting compositions must exhibit good physical and chemical characteristics: minimized hygroscopicity, not getting packed, non-toxic, non-flammable, non-explosive, lowering eutectic temperature of water-salt solutions, and causing minimum chemical corrosion of metal, concrete, road pavements, and other surfaces. Whereas the most commonly used chemicals are chlorides which are rather corrosive salts, it is safer for environment and people when prior to use they are mixed with corrosion inhibitors: the substances that added in low amounts dramatically reduce the speed of metal corrosion. Standard inhibitors for such compositions are amines, phosphates, zinc salts, borates, silicates or chromates. The recent decade sees increasing number of patents where organic substances or organic product production waste with good water solubility characteristics are added as corrosion inhibitors to snow and ice melting compositions. The U.S. patent 4676918 provides a snow and ice melting composition where chloride salts are mixed with ethyl alcohol production waste which amount in the mixture is 20-90 % by weight.
The U.S. patent 4824588 introduces a method to obtain a snow and ice melting composition by mixing chloride salts with saccharinic acid and lignosulphonates.
However, this is specific waste with very high amount in compositions, therefore their compositions with salts are intended for use in solution form.
There is a known method (WO 2013068299) where snow and ice melting agent contains a group of substances consisting of sodium chloride, calcium magnesium acetate, calcium chloride, magnesium chloride, calcium acetate, sodium acetate, sodium formate, potassium formate, lignin derivatives, and molasses.
The use of such chemical compounds for varied nature for preparing of snow and ice melting composition can reduce cross-dissolving of ingredients and cause reactions between them, which would impair physical properties of the composition and lead to the composition getting packed, furthermore, certain ingredients are toxic and expensive.
The closest related art can be found in the patent CA 2287582 and is a snow and ice melting composition which basic part consists of salt, sodium chloride, mixed with a sugar production waste, specifically, corrosion inhibitor molasses. The concentration of the molasses is in the range of 5-25 % by weight. A disadvantage of the said art is that such a composition must be used immediately after mixing, as it quickly gets limp and packed, making its application complicated. Moreover, large quantity of molasses is worrisome as well, because it can be aggressive to common steels.
SUMMARY OF THE INVENTION
The purpose of invention is to obtain a snow and ice melting composition that is effective in low temperatures (-20-30°C), non-toxic, uniformly mixed, not getting packed, not dusty, with minimum hygroscopicity, evenly applicable even after prolonged storage in warehouses or other similar locations, and minimally cause a corrosion of concrete and metal structures and parts thereof as well as to roads. The main ingredient in the being patented snow and ice melting composition is sodium chloride, molasses which is used as corrosion inhibitor, and carbamide (and, if needed, ammonium dihydrogen phosphate) is added to promote action of inhibitors and composition solubility. Carbamide is mixed with molasses and causes action of molasses as corrosion inhibitor and also accelerates melting of snow or ice. The amount of carbamide in the composition is approximately 0.1-5.0 % by mass and the amount of ammonium dihydrogen phosphate in the composition may be 0.1 - 5.0 % by mass. The amount of ammonium hydrogen phosphate in ammonium dihydrogen phosphate may be up to 15 % by mass. Total amount of carbamide and ammonium dihydrogen phosphate in the composition is 0.2-5.0 % by mass.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The molasses we use is a by-product of sugar production from sugar beets at "ARVI cukrus" in Marijampole town, which is obtained by centrifugation of crystal sugar. Dry matter content in molasses obtained in processing sugar beets is in the range of from 75 to 85 % by mass. Dry matter content in molasses is composed of: 44 to 53 % by mass of saccharides containing up to 51 % by mass of saccharose, about 1 % by mass of inverted sugar, 1 % by mass of raffinose, 14.5 to 15 % by mass of nitrogen compounds, 16 to 17 % by mass of other non-sugar substances, and 8.5 to 12 % by mass of ash.
Molasses contain nitrogen compounds: amino acids, amides, glutamic and betainic acids as well as lactic, acetic and formic organic acids.
Water content in molasses is 17-25 % by mass.
Density (at the temperature of 20°C) is 1.41 g/cm3.
Viscosity is temperature-dependent. The dynamic viscosity of molasses (measured with rotational viscometer) at the temperature of 25°C is approximately 25 poises.
Cinematic viscosity at different temperatures is the following: 750 mm2/s at 40°, 216 mm2/s at 60°, 72.4 mm2/s at 80°.
The main technical characteristics of snow and ice melting compositions were examined by the following methods.
Steel corrosion was determined electrochemically. Customised St-3 steel plates with low carbon content were used for electrochemical analysis. An universal potentiostat/galvanostat PGSTAT-12 (the Netherlands) was used for electrochemical analysis.
Kinetic characteristics of corrosion were determined by referring to steel polarisation curves at E=ln j coordinates (Stem diagram). Corrosion potential {Ekl) and corrosion current (jk,) were determined by referring to Stern diagram.
Holding that corrosion occurs uniformly on the entire surface of steel, corrosion penetration depth was calculated: pn
where: j is corrosion current, μΑ/cm2; M is iron molar mass, 55.847g/mol; n is the number of electrons involved in electrode reaction, 3; p is steel density, 7.85 g/cm3; k is constant, 3.27Ί 0"3, mrrvg/| A-cm.
Composition packing was determined by using fertilizer packing determination methodology.
Dust content was determined visually.
Melting speed was analysed by pouring equal amount of salt (10 g) over ice samples and applying a galvanometric method to measure mass decrease in the sample (ice and salt) over certain time. Ice samples were prepared by freezing 100 cm3 of water in -20°C temperature. Melting analysis was carried out at the same temperature. The data were converted to mass percents.
Moisture content was determined for initial sample (of the newly produced composition) and later for the sample that spent 7 days outdoors. Moisture content was determined with laboratory-grade moisture meter KERN MLS, drying it to constant mass by gradually increasing temperature to 120°C. The results are given as the average of three measurements expressed in mass percents.
The essence of the invention is illustrated by the following examples.

Carbamide additive reduces metal corrosion speed by about 10 times and lowers moisture absorption (hygroscopicity). The product obtained emits no dust and does not get packed. Use of carbamide together with ammonium dihydrogen phosphate brings about even more positive effects: metal corrosion speed decreases by up to 20 times and moisture absorption gets lower.

The proposed patent would simplify production, storage and use of snow and ice melting compositions, improve their efficiency, and reduce negative effects on environment. Substances used for production of the composition are non-toxic, non-explosive and relatively cheap, the production itself requires no sophisticated equipment or special conditions.
