Description
Изобретение относитс к области получени силикатов щелочных металлов в частности двойной соли метасиликато натри и кали , примен емой в качестве основного компонента в моющих средствах дл обезжиривани деталей, при отбелке тканей и как депрессор пустой породы при флотации медно-молибденовых руд.This invention relates to the field of the production of alkali metal silicates, in particular, sodium metasilicate sodium and potassium double salt, used as a main component in detergents for degreasing parts, for bleaching fabrics and as a waste rock depressant for flotation of copper-molybdenum ores.
Известен способ производства полисиликатов щелочных металлов путем гидротермальной обработки в строго контролируемых услови х тонких водных дисперсий, состо щих из двуокиси кремни и гидроокиси щелочного металла с последующей сушкой полученной реакционной смеси распылением, дроблением образовавшейс твердой массы и перемешиванием во вращающихс барабанах 1. Данный способ,однако,достаточно сложен и длителен.A known method for the production of alkali metal polysilicates by hydrothermal treatment under strictly controlled conditions of thin aqueous dispersions consisting of silicon dioxide and alkali metal hydroxide, followed by drying the resulting reaction mixture by spraying, crushing the resulting solid mass and mixing in rotating drums 1. This method, however , quite complex and durable.
Известен способ получени двойной соли метасиликатов натри и кали путем смешени натриевого - силикатного раствора с содержанием NaOH 145 г/л и SiOj 115 г/л с раствором едкого кали концентрации 400 г/л с последующей упаркой полученного смешанного раствора, содержащего NaOH 103 г/л, КОН 118 г/л и SiOA method is known for producing a double salt of sodium and potassium metasilicates by mixing a sodium-silicate solution with an NaOH content of 145 g / l and SiOj 115 g / l with a solution of potassium hydroxide at a concentration of 400 g / l followed by evaporation of the resulting mixed solution containing NaOH 103 g / l KOH 118 g / l and SiO
92 г/л до концентрации NaOH 275 г/л, КОН 285 г/л, Si02 210 г/л и общей щелочности по 390 г/л, введением затравки дев тиводного метасили| ата натри На251Оз9Н2 О и охлаждением раствора с дальнейшим центрифугированием полученной пульпы 2. Недостатками этого способа длительность и сложность процесса, 92 g / l to a concentration of NaOH of 275 g / l, KOH 285 g / l, SiO2 210 g / l and total alkalinity of 390 g / l, the introduction of a seed of nine-water metas or | sodium Na251Oz9N2O and cooling the solution with further centrifugation of the obtained pulp 2. The disadvantages of this method are the duration and complexity of the process,
0 а необходимость процесса упарки разбавленного раствора и охлаждени упаренного раствора на вакуум-| ристаллизационной установке требуют больших расходов тепла и пара.0 a need for the process of evaporation of the diluted solution and cooling of the evaporated solution on the vacuum | Installation systems require high costs of heat and steam.
