Description
Изобретение относитс к очистке отл-ивок от горелой земли керамики, и в частности к Области точного лить по выплавл емым модел м.The invention relates to the cleaning of drift from the burned earth of ceramics, and in particular to the Area of Precision Casting on Melted Models.
Известен способ очистки отливок от горелой земли и керамики обработкой в водных растворах щелочей.A known method of cleaning castings from the burned earth and ceramics by treatment in aqueous solutions of alkalis.
.Предложенный способ отличаетс от из .вестного тем, что очистку провод т в автокл .аве при температуре выше 150°С и давлении выше 5 ати, что позвол ет интенсифицировать процесс.The proposed method differs from the one known in that the cleaning is carried out in an autoclave at a temperature above 150 ° C and a pressure above 5 atm, which makes it possible to intensify the process.
Способ заключаетс в том, что очистку отливок провод т обработкой водным : растворами П1елочей в автоклаве при температуре вьппе 150°С и давлении выше 5 ати.The method consists in the fact that the cleaning of castings is carried out by treatment with water: solutions of Pyrolys in an autoclave at a temperature of 150 ° C and a pressure above 5 MPa.
Как показали лабораторные опыты, температура 50%-ного раствора едкого кали при 5 ати равна 165°С, при 8 ати-186°С, при 10 ати - 200°С, и соответственно ускор етс процесс очистки.As shown by laboratory experiments, the temperature of a 50% aqueous solution of potassium hydroxide at 5 MPa is 165 ° C, at 8 MPa-186 ° C, at 10 MPa — 200 ° C, and the cleaning process accordingly accelerates.
Применение данного способа позвол ет в 3-5 раз интенсифицировать очистку.The application of this method allows to intensify cleaning 3-5 times.
