PLPublished on April 8, 1957 MUSM LIBRARY Al Urzeru Pr, fe r, \ POLSKA RZECZYPOLITEJ PEOPLEJ PATENT DESCRIPTION No. 39749 KI. 38 h, 2/02 Glóumy Instytut Górnictira *) Katowice, Poland Manufacturing method of fire and fungus preparation for wood The patent was valid from November 18, 1955. So far, there are no known preparations for wood with an effective universal action, i.e. at the same time reducing The flammability of wood and those which are toxic to fungi - pathogens of wood. There are preparations with one-sided action, i.e. either fire-retardant, such as phosphate-ammonium or antifungal salts, such as fluorine, fluorosilicate, arsenic and other salts. that reduces the flammability of wood and, at the same time, has a toxic effect on fungi, consisting in stabilization by oxidation? with air of sulphite slurries and then bromination or chlorination of the obtained half-product. The anti-fire action of the preparation according to the invention consists in decomposing the preparation under the influence of high temperatures with separation •) The patent owner stated that the authors of the invention are Eng. Wladyslaw Mil - Kowski and Eng. Bronislaw Zyska, MSc. hydrochloric acid, which causes wood charring and the formation of an insulating layer, and the formation of a foamy coating. The antifungal effect of the preparation is based on the toxic effect of chlorinated phenolic fragments of chlorolignin sulfonic acids and resembles the action of the known antifungal preparation of pentachlorophenol. Coal has two advantages. On the one hand, it is possible to increase the safety of work in PW mines and reduce the overall losses caused by mine fires in the mining works, on the other hand, in a single technological process of production and impregnation of wood, anti-fungal protection is obtained, simultaneously eliminating the import of sodium fluoride, previously used at 50% for the anti-fungal impregnation of mine wood. The preparation according to the invention is used in such a way that the wood is saturated with it by the bathing method or the vacuum-pressure method. Example: Preparation reducing the fire of wood and having a toxic effect for fungi are obtained by air oxidation of crude sulphite slurries in the presence of catalysts (for example, a copper mesh) at boiling point for 5 to 9 hours. In the second operation, the oxidized sulphite liquors are chlorinated or brominated in the presence of a catalyst (eg, ferric chloride) at a temperature of 60-80 ° C until the weight gain is 30-60% with respect to the dry substance of the liquors originally used for production. In the third operation, the preparation is neutralized with gassy ammonia to pH = 6 + 8. The preparation works effectively against fire when diluted with water, if it still contains approx. 3% of the original dry substance, contained in the crude sulphite liquors, processed as in the given example.
