Description
Najdluzszy czas trwania patentu do 26 czerwca 1954 Wynalazek niniejszy stanowi dalsze udoskonalenie patentu nr 28699 i ma na celu umozliwienie w sposób szczególnie do¬ godny otrzymywania nitrocellonów do prze¬ sycania plótna i drewna w konstrukcjach lotniczych o obnizonej palnosci blony.Okazalo sie bowiem, ze oprócz substan¬ cji wymienionych w patencie nr 28699 do celu tego nadaja sie równiez i inne sub¬ stancje, a mianowicie napelniacze, sluzace do dalszego zmniejszenia palnosci. Napel- niaczami takimi moga byc weglany ceru, manganu, llitu, tlenochlorki magnezu, cyn¬ ku, olowiu, bizmutu i antymonu, borany nie¬ rozpuszczalne w wodzie, takie jak boran magnezu, wapnia, baru. strontu, cynku, gli¬ nu, zelaza, kobaltu, niklu, manganu, olowiu, miedzi, oraz fosforany nierozpuszczalne w wodzie, takie jak fosforan magnezowo-amo- nowy, fosforan wapnia, baru, strontu, cyn¬ ku, zelaza, kobaltu, niklu, manganu, olowiu, miedzi; zwlaszcza dobre wyniki uzyskuje sie przez równoczesne zastosowanie fosfo¬ ranów i boranów- Wedlug wynalazku niniejszego nitrocel¬ lon moze zawierac równiez substancje sta¬ bilizujace nitroceluloze, w postaci np. cho- lesteryny i mocznika. PLThe longest term of the patent until June 26, 1954 The present invention is a further improvement of the patent No. 28699 and is intended to make it possible to obtain nitrocellons for saturation of canvas and wood in an aircraft construction with reduced flammability in foil in a particularly convenient way. of the substances mentioned in Patent No. 28,699, other substances are also suitable for this purpose, namely, fillers, which serve to further reduce the flammability. Such fillers may be carbonates of cerium, manganese, lithium, oxychlorides of magnesium, zinc, lead, bismuth and antimony, borates insoluble in water, such as magnesium, calcium, barium borate. strontium, zinc, aluminum, iron, cobalt, nickel, manganese, lead, copper, and water-insoluble phosphates such as magnesium ammonium phosphate, calcium phosphate, barium, strontium, zinc, iron, cobalt, nickel, manganese, lead, copper; especially good results have been obtained by the simultaneous use of phosphates and borates. According to the present invention, nitrocellon may also contain nitrocellulose stabilizing substances, in the form of, for example, cholesterine and urea. PL
