Description: Phosphate composition and its utilization The invention relates to fields such as medicine, agriculture, cattle-raising and construction. The invention deals with water solutions with cold solidification capacity, which are known as mineral adhesives or astringents and are synthesised oxide, phosphate or metal by means of ortho, pyre-, tri-, poly-, or any other phosphorus acid. They can be applied within medicine: surgery, dermatology, dentristry, oncology, pharmacology and other branches. In agricultural use: as a means of curing plant diseases; within veterinary - as a means for preventive maintenance and curing of animal diseases; within construction - as a anticorrosive, fire-resistant, decorative, hydro¬ electric isolating covers, ceramic tiles, concretes, which protect against radiation, as well as for producing other composite materials. There are well known examples of phosphate adhesives, containing zinc and aluminium, and phosphatic adhesives containing aluminium and magnesium, which are utilised both in dentistry as a means for producing dental cements and in construction - as a means for producing fire resistant covers (1,2), through thermos treatment. The phosphate binder of calcium is used in production of toothpastes, it can be served as an ingredient of animal food, can be used for production of anticorrosive and fire resistant covers in construction, through heat processing ( 1 ,2). There is also the example of phosphate binder, which contains iron polyphosphate, polyphosphoric acid and water (3). It is obtained through adding Fep 3 to orthophosphoric acid and further boiling, during which the water vaporises and polycondenses and iron and tripolyphosphates emerge. Thus obtained phosphate binder is used for producing fire resistant material through heat processing. The selected prototype for the proposed invention is the phosphate composition as a binder (4), containing iron oxide solution in polyphosphoric acid, water and in addition highmolecular polysacharide or its derivative with the following ratio of components, in massive parts: polyphosphoric acid -100, iron oxide - 36-53, highmolecular polysacharide or its derivative - 0,5 - 3,5, water - 15 -30. The disadvantage of the composition is the high cost of producing, resulting from: (i) the inefficient utilisation of polyphosphoric acid and electric (heat) power; (ii) the toxicity of the solution, caused by the emergence of detrimental (harmful) soluble and gaseous materials after dissolution of polysacharide in acid environment during boiling; (iii) the thermos (heat) treatment necessary for solidification are characteristic of polyphosphates. The proposed invention envisions the reduction of the cost of producing, toxicity and the period of cold solidification through exclusion of polyphosphoric acid and polysacharide from composition contents, as well as exclusion of electric (heat) energy from the technological process. The substitution of inefficient and expensive polyphosphoric acid with orthophosphoric acid results in a decrease of the composition cost of producing and increases the cold solidification capacity. The synthesis proceeds without supplying electπc (heat) energy from outer sources, but rather by means of exothermous reaction ongoing within reaction area which causes the reduction of cost of producing. The exclusion of polysacharide from the contents of the invention results in the decrease of toxicity level. The phosphate composition is obtained through: Adding water, while stirring continuously, iron oxide powder and any metal powder for example, aluminium to orthophosphoric acid calculated on 100% acid, for maintenance of temperature regime within the reaction area and for neutralising the extra acidity, the ratio of components in massive parts being the following: heat liberated after the exothermal reaction (40°-50°) is enough for dissolution of iron oxide and metal powder which requires holding the mass for 2 hours. The output of the reaction represents transparent, brownish sticky liquid, compactness of which comprises 1.50 gr/m 3 , while the ratio of phosphate ion to the iron ion equals 2,0 -4,0. The solution is stable for about 2 years. The iron oxide weight in the proposed invention above 41 will cause the dissolution and solidification of the solution, while below 41, it will result in reducing the cold solidification capacity. Substitution of aluminium powder by any other metal powder, e.g. Fe, Ca, Mg, Zn, Co, Ni, Y, Sc etc, will alter the composition characteristics, namely, it will either increase or decrease cold solidification capacity. The metal powder weight above 2.5 in the reaction area will heighten the temperature level to 120°-130° and will result in sticking of dissolved particles and orthophosphate anion will turn into polyphosphate. If metal powder weight is below 0.5, the temperature within the reaction area remains unaltered and the dissolution process is carried at a slow speed, over the period of several days. The weight of water above or below the normalised level in the reaction area will violate the temperature regime. The Table 1 and 2 below demonstrate the properties of the iron phosphate solution of a specific composition. The phosphate composition, unlike its prototype and its analogues is characterised by bactericidal, virucidal and fungicidal properties. The recorded data show that among phosphate admixtures only copper phosphate is characterised by antimicrobial properties and its utilisation in the preparation of fungicides is recommended. Within the proposed invention the preliminary clinical investigation of the phosphate composition is conducted at the experimental and clinical scientific research laboratory attached to the state Medical University; at the Institute of Labour Hygiene and professional diseases of the Health Ministry of Georgia; at the scientific centre dealing with particularly dangerous infections of the Institute of Sanitary and Hygiene The research has revealed that the phosphate composition in water solutions kill the microbes of plague, pseudotuberculosis, salmonella, colibacillus, dysentery, golden staphylococcus microbes, grippe, hepatitis, West Nile fever and oncoviruses (Table 3,4) Within 1 -5 minutes after treatment the equipment, clothes, premises, laboratory vessels, patients excrements are sterilised As regards its toxicity, it is well known that inorganic admixtures of 5 valence phosphorus are one of the harmless admixtures for humans Besides, the organism absorbs phosphorus in ortho- foπn and PO anion is considered to be the one of the most significant component of a "physiologically" living organism, which regulates the buffer HPO 4 2 H, PO 4 " system of blood The results of toxicological, pathomorphological, histological, pathophysiological, bacteriological, physiological, biochemical, neurological, i munological studies of the phosphate composition have proved that the solution does not alter cardiovascular and respiratory system parameters, neither the functions of liver and kidneys, has no impact on peripheral blood indicators and the immune status of the body, causes no change in cell. There are no indications of allergic reactions The solution fulfils the deodorant function of dismissing unpleasant odours Both the phosphate composition and its production processes are ecologically safe The abovementioned researches have proved that the solution is neither toxic nor cancerogemc and can be used both for external use and drinking.
