Description
Gdy cienka plytke cementowa, o gru¬ bosci 3—-8 mm, poddamy w stanie swie¬ zym wielkiemu cisnieniu (od 400 atmo¬ sfer wzwyz), to plytka nie uksztaltuje sie, lecz pod miazdzacem dzialaniem cisnienia rozleci sie; z tego powodu nie mozna z czystego cementu plytek takich ksztal¬ towac.Przedmiot niniejszego wynalazku sta¬ nowi sposób umozliwiajacy sporzadzanie takich plytek przy uzyciu powyzszego ci¬ snienia. Sposób ten polega na tem, ze do wspóldzialania uzywa sie wlókna ce¬ lulozowego. Do tego celu nadaja sie naj¬ lepiej wlókna papiernicze, odpowiednio "ozdrobnione (rozmielone). Gdy wlókna te w ilosci 5—20% zmiesza sie w holen¬ drze z 95—80% cementu i odpowiednia iloscia wody, a nastepnie uksztaltuje plyt¬ ke, odessie wode, podda cisnieniu 400 at¬ mosfer i osuszy, — otrzymuje sie plytke trwala i wytrzymala. PLWhen a thin cement tile, 3-8 mm thick, is subjected in a fresh state to high pressure (from 400 atm spheres upwards), the tile will not form, but will break under the pressure of the pressure; for this reason, the tiles cannot be shaped from pure cement. It is an object of the present invention to provide a method which enables such tiles to be prepared using the above pressure. The method is that cellulose fiber is used for the interaction. Paper fibers, suitably "milled", are best suited for this purpose. When 5-20% of these fibers are mixed with 95-80% of cement and a suitable amount of water in a holster, and then it forms a plate. , suck the water, pressurize 400 atmospheres and dry, - a durable and durable plate is obtained.
