Description
Najdluzszy czas trwania patentu do 16 sierpnia 1947 r- W patencie Nr 16729 opisano sposób sklejania cienkich warstw drzewa i fornie¬ ru, jak równiez sklejanie warstw fornierów z warstwami blachy metalowej.Zauwazono, ze jezeli przy sklejaniu for¬ nieru niektóre" warstwy fornieru zamienic warstwami tkanin lub papierni, przesycone- mi roztworem bakelitu, i po wysuszeniu u- lozyc je na sobie i poddac cisnieniu od 2fl£ do 300 at. przy temperaturze 120 — 220°C, to otrzymuje sie materjaly o wlasnosciach podobnych dlo opisanych w patencie glów¬ nym. Materjaly te cechuje wielka elastycz¬ nosc; sluzyc one moga do wyrobu kól zeba¬ tych, czesci maszyn, karoserji samochodo¬ wych i samolotowych, wykladania- scian, fa¬ brykacji mebli i L d Przyklad L 3 warstwy fornieru drzew¬ nego, przepojonego roztworem bakelitu, po¬ krywa sie tkaninami, przepojonemi roztwo¬ rem bakelitu, poczem poddaje sie w prasie hydraulicznej cisnieniu 200 at przy tempe¬ raturze 200°C.Przyklad II. 3 warstwy fornieru drzew¬ nego, przepojonego roztworem bakelitu, przeklada sie dwiema warstwami papieru, przepojonego roztworem bakelitu, poczem poddaje sie w prasie hydraulicznej cisnie¬ niu 200 at przy temperaturze 200°C. PLThe longest duration of the patent until August 16, 1947 - Patent No. 16729 describes the method of gluing thin layers of wood and veneer, as well as gluing layers of veneers with layers of metal sheet. fabrics or paper mills, saturated with bakelite solution, and after drying, put them on top of each other and pressurize from 2 to 300 at. at a temperature of 120 - 220 ° C, to obtain materials with properties similar to those described in the patent These materials are characterized by great flexibility; they can be used for the manufacture of toothed wheels, machine parts, car and aircraft bodies, lining of walls, furniture embossing and Example L 3 layers of wood veneer, soaked with bakelite solution, covered with fabrics, soaked with bakelite solution, and then subjected to a hydraulic press pressure of 200 at a temperature of 200 ° C. Example II. 3 layers of wood veneer, soaked with bakelite solution, put on two layers of paper, soaked with bakelite solution, and then subjected to a hydraulic press of 200 atm at a temperature of 200 ° C.
