Abstract

A találmány tárgya eljárás oldható, savanyú, 0,3-0,6 Na/P aránnyal, 77tömeg% feletti P2O5-tartalommal, 20% alatti Na2O-tartalommal és 3-10%maradék víztartalommal rendelkező polifoszfátok előállítására, amelyetaz jellemez, hogy 10-30 közepes lánchosszúságú, lánc alakúpolifoszfátok képzésére a foszfátok vizes oldatát beszárítják és 400-600 °C-on 30-180 percig megömlesztik, és az olvadékot üvegszerű termékképződése mellett lehűtik, ahol is az olvasztás alatt az olvadékkalérintkező atmoszféra vízgőznyomását 0,1-0,5 bar értéken tartják. Atalálmány tárgya továbbá készülék polifoszfátoknak az ezzel azeljárással való előállítására, amely készülék egy csőkemencéből (1)áll, amely egy kvarccsőből (3) álló béléssel van ellátva, amelyben egykissé megdöntött, az olvadék lefolyását megvalósító olvasztókád (2)van elrendezve, amelyhez a foszfátok bevezetésére szolgáló csővezeték(4) és a polifoszfátolvadékokat elvezető csővezeték (5) csatlakozik,továbbá egy, a vízgőz-hozzávezetésre szolgáló csővezeték (9) vanelrendezve. ÓThe subject of the invention is a process for the production of soluble, acidic polyphosphates with a Na/P ratio of 0.3-0.6, a P2O5 content of over 77% by weight, a Na2O content of less than 20% and a residual water content of 3-10%, which is characterized by the fact that 10- To form 30 chain-shaped polyphosphates with a medium chain length, the aqueous solution of the phosphates is dried and melted at 400-600 °C for 30-180 minutes, and the melt is cooled with the formation of a glass-like product, where during melting the water vapor pressure of the atmosphere in contact with the melt is reduced to 0.1-0.5 is kept at bar value. The subject of the invention is also a device for the production of polyphosphates using this method, which device consists of a tube furnace (1) which is lined with a quartz tube (3), in which a slightly tilted melting tank (2) is arranged for the flow of the melt, to which the phosphates are introduced pipeline (4) and the pipeline (5) for draining the polyphosphate melts are connected, and a pipeline (9) for the water vapor supply is also arranged.
