Inventors of the invention: mgr Boguslaw Nowicki, mgr Leonard Mezynski, mgr Michal Grzeskowiak The owner of the patent: Unia Przemyslu Ziemniaczanego, Poznan (Poland) iaiDLOTSKA "Method for producing starch soluble in cold water. ' =:; "-: -: - suitable for use in the production of paper M" —- ^ 'It is known to use either plain or prepared starch for the production of paper. It acts as a binder and improves the mechanical properties of the paper. Raw starch is used only in 5-30%, while modified starch gives better results and its utilization reaches 90%. Modified starch for paper production is usually obtained by chemical treatment 10 and thermal starch suspension. This treatment is carried out by treating the starch slurry with mineral acids or salts, followed by roller drying. In this way, preparations are obtained which are soluble in cold water and improve the mechanical properties of the paper. It has turned out that it is possible to obtain starch preparations which give better results than the known preparations with a higher dispersibility and better water solubility, distinguished by a light color, good solubility and fiber sticking properties, if the treatment of an aqueous starch suspension with a concentration of 100 kg. starch for 130 - 150 kg. water by oxidation in such a way that its viscosity decreases by about 3 times, and then on the action of alkali metal salts and borates regulating the concentration of hydrogen ions, so that the magnesium hydroxide does not lose during the addition of magnesium salts and subjecting to the mass thus prepared is heat-treated on drying rollers in order to direct and dry. It is preferable to preheat the mass obtained to gluing prior to processing on the rollers. It is important to obtain a starch preparation showing the above-mentioned characteristics to maintain the correct ratio of added amounts. Oxidized water as well as indoxides, persulphates, etc. are suitable as oxidizing agents. processing and reaction temperature. The obtained mass is dried on a roller dryer at a temperature in the range of 120 - 160 ° C, which is preferably at a temperature of 130 ° C and adding, in addition to the above-mentioned ingredients, sodium or magnesium salts of alkyl arylsulfonates. a new explanation of the method according to the invention. It should be understood that the invention is not limited to a given example and that the composition and quantity may be varied while retaining the spirit of the present invention. In the following example, parts should be understood as parts by weight. 49336/3 49 336 4 Example: For 100 parts of potato flour with 20% moisture, add 100 parts of water and 0.1 parts of hydroxide, 0.5 parts of sodium carbonate and 0.1 parts of 30% hydrogen peroxide and warm stirring to 50 ° C for 30 - 50 minutes. 0.2 parts of borax and 3.0 parts of magnesium sulfate are then added. The mass thus obtained is dried on drying rolls at a temperature of 150 ° C. The dried product obtained in the form of flakes is crushed. The reaction can also be carried out at a temperature lower than 50 ° C, e.g. at room temperature, appropriately prolonging the duration of the reaction. The proportion is important for obtaining good solubility and properties. cellulose fiber binding./ Moreover, it turned out that such a product can / also be used in other industries for other purposes, e.g. to accelerate the sedimentation of suspensions!
