Lepiszcze uplastycznia sie glicery¬ na, glikolem lub kamfora — zaleznie od przewidzia¬ nych wymagan technicznych, po czym miesza sie kruszywo korkowe z lepiszczem. Z materialu tego formuje sie plyty przez sprasowanie przy zastoso¬ waniu cisnienia od 1,5 do 5 atm, zaleznie od wy¬ maganej elastycznosci i twardosci. Nastepuje dalej *) Wlasciciel patentu oswiadczyl, ze twórcami wynalazku sa inz. mgr Edward Boniecki i inz. mgr Tadeusz Marganiec. suszenie plyty przez okres 15 — 30 minut, zaleznie od grubosci plyty, u temperaturze 160° do 180°, wreszcie po wyjeciu plyty z prasy klimatyzuje sie ja przez okres 6 tygodni w suchym przewiew¬ nym pomieszczeniu w temperaturze okolo 20° C.Z tak przygotowanej plyty wykonuje sie uszczelki zwlaszcza do samochodów, które pod pewnymi wzgledami znacznie przewyzszaja wlasciwosci obecnie uzywanych uszczelek przez przemysl mo¬ toryzacyjny. PLPublished on October 30, 1956 «IBIBLM EKA3;, v.'J ^ and POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 39309 Ki. 38 h, 6/01 Poznanskie Zaklady Wyrobów Korkowych *) Przedsiebiorstwo Panstwowe Poznan, Poland. Grinding the cork waste into crumb and sifting out unnecessary granulation, the material is obtained with the following grain sizes: a) 1 - 3 mm b) 2 - 3 mm c) 2 - 5 mm, which is stuck together with animal bone and skin binder in the amount of 12 5% of the dry weight of the binder with respect to the weight of the cork aggregate used in a granulation of 1-3 mm or 10% of the dry weight of the binder with respect to the aggregate of granulation 2-3 or 2-5 mm. The binder is plasticized with glycerin, glycol or camphor - depending on the foreseen technical requirements, and then the cork aggregate is mixed with the binder. This material is formed into sheets by pressing with a pressure of 1.5 to 5 atm, depending on the required flexibility and hardness. Next *) The owner of the patent stated that the inventors of the invention are Edward Boniecki, MSc and Tadeusz Marganiec, MSc. drying the plate for a period of 15-30 minutes, depending on the thickness of the plate, at a temperature of 160 ° to 180 °, and finally, after removing the plate from the press, it is air-conditioned for 6 weeks in a dry ventilated room at a temperature of approx. 20 ° C of the plate prepared in this way seals are made, in particular for cars, which in some respects significantly exceed the properties of seals currently used by the automotive industry.
