Abstract

Atskiestas natrio silikato tirpalas, esant 70-80 °C, tūtos pagalba smulkiai purškiamas ir įvedamas į atskiestą skaidrų šarmą, gaunamą gaminant Al(CH)3 Bajerio metodu. Savaime nusėdanti nuovarose medžiaga prie 70-80 °C brandinama tol, kol susidaro smulkaus kristalingumo miltelių pavidalo 4A tipo ceolitas, kurio granulometrinės sudėties d50 reikšmė neviršija 3 µm. Gauti tokiu būdu ceolito milteliaiiš esmės neturi grito ir nurodyto dalelių stambumo dėka tarp kitko gali pakeisti fosfatus skystose plovimo priemonėse.Dilute sodium silicate solution at 70-80 ° C by spray nozzle is finely sprayed and introduced into the diluted clear alkali produced by Al (CH) 3 Bayer method. The self-sedimenting material at 70-80 ° C matures until a crystalline powder-like zeolite type 4A is formed with a d50 value of less than 3 µm in the granulometric composition. In this way, the zeolite powder obtained essentially has no grit and, due to the bulk of the particles, may alternatively replace phosphates in liquid detergents.
