Description

Pozostalosc, otrzymana po odparowa¬ niu odpadkowych lugów blonnikowych, jest w wysokim stopniu higroskopijna, co utrudnia znacznie stosowanie jej w farbiar- niach, garbarniach i t, d. Usilowano juz nie¬ raz usunac te niedogodnosci. Proponowane jednak sposoby polegaly prawie wylacznie na obrabianiu rzeczonych lugów srodkami chemicznemi, a wiec wymagaly stosowa¬ nia metody zwiazanej z duzemi kosztami.Zauwazono obecnie, ze mozna otrzy¬ mac produkty niehigroskopijne przez od¬ parowanie odpadkowych lugów blonniko¬ wych w temperaturze wyzszej od tempera¬ tur stosowanych dotychczas przy odparo¬ wywaniu w prózni lub w aparatach odkry¬ tych, W celu otrzymania ciala o bardzo znacznej odpornosci na dzialanie powietrza, mozna poddac otrzymane w sposób dowol¬ ny z lugów blonnikowych cialo stale po¬ nownej obróbce w temperaturze podwyz¬ szonej.Przyklad, Produkt otrzymany z lugu blonnikowego w temperaturze 140° C na walcu suszarnianym ogrzewa sie przez krót¬ ki czas w temperaturze 180° C. Otrzymuje sie drobny proszek, który jest nieco rozpu¬ szczalny w wodzie i odporny na dzialanie powietrza. PL PLThe residue obtained after the evaporation of waste fiber hips is highly hygroscopic, which makes it very difficult to use in dye works, tanneries, etc. Attempts have already been made to overcome these drawbacks. The proposed methods, however, consisted almost entirely of treating said liquors with chemicals, and therefore required a high-cost method. It has now been found that it is possible to obtain non-hygroscopic products by evaporating the waste fiber at a temperature above the temperature of In order to obtain a body with a very high resistance to the action of air, the body obtained by any of the fiber lugs can be subjected to a new treatment at an elevated temperature. Example: A product obtained from a fiber slurry at 140 ° C. on a drying roller is heated for a short time at 180 ° C. A fine powder is obtained which is slightly soluble in water and resistant to air. PL PL
