SU92112A1 - The method of obtaining the drug (collosilicate), which is a colloidal solution of sodium salt of silicic acid - Google Patents

Description

The method is as follows. The lumps of sodium silicate are crushed, cleaned with dirt, washed with Eodo11, and then milled into sharpening mills in a minute; Shiy Poroiuk. The resulting polyfluoros is washed with water, after which it is loaded into a boiler or autoclave, to which water is added at the rate of one part of the forces: kata to three parts of water. The mixture is boiled for 3-4 hours. before the appearance on the surface of the gloss, she film. After this, the solution is settled and filtered.

After filtration, about as much water is added to the remaining precipitate in the boiler or in the autoclave as it was in the first batch, after stirring before appearing on the surface of the solution inciiK ;, because of OTCTaiinaiOT and f;

This is done until the film is cut off. The resulting filtrates are again boiled in a melter of 1–4-6 h. to obtain a solution beats. at. L45-1.48 and depending on the purpose for which the collosilicate is prepared. After that, the solution is poured into bottles and sealed.

To obtain the collosilicate dryly, the coagulum is taken. forming in a boiler or in an autoclave with Vapko F1 ltrat pln during storage of the solution for 9.9122, as well as by precipitating the colloidal particles with alcohol, placed on plywood or sheet iron and dried at room temperature; while the coagulum is rotated from time to time for uniform drying.

In addition to To.ro, it is possible to obtain a collosilicate in a dry form from a solution with a specific gravity of 1.50, for which the solution is poured in a thin, even layer onto iron sheets with curved flange | Mi and dried as coagulum.

Claims (3)

1. A method for obtaining a collosilicate preparation, which is represented by a colloidal solution of sodium silicate, about one lump and with the fact that sodium silicate is crushed to a powder, washed with water, mixed with water in a ratio of 1: 3 , boil for 3-4 hours. until a solution is obtained on the surface of a glossy film, after which the solution is settled, filtered, the precipitate is treated in the same way until the silica particles are completely removed, the resulting filtrate is evaporated again for 4 hours. before receiving ud. at. a solution of 1.45-1.48. 2. Alteration of the method according to claim 1, from l and h and w, it so that the resulting solution of specific gravity 1.50 is dried in the open air to obtain a dry powder. 3. Change the method of and. I, this is due to the fact that the solution of collosilicate of any specific gravity is precipitated with alcohol, the resulting coagulum is dried in the open air to obtain a dry powder.
