Description
Technical field
The present invention relates to silicon materials preparation field, and in particular to a kind of production method of liquid sodium silicate.
Background technology
Sodium metasilicate is to develop most commonly used product in inorganic silicon compound, is used as a kind of basic inorganic industrial chemicals, silicon
Sour sodium purposes is quite varied, almost throughout each department of national economy.For example, as industrial chemicals, for produce white carbon,
The various silicates products such as zeolite molecular sieve, silica gel, Ludox, sodium metasilicate；In light industry, as water softener,
Settling agent；It is used to manufacture quick hardening cement, acid-resistant cement, dubbin, soil-solidified-agent, refractory material etc. in building trade；
Agriculture aspect, contains silicon fertilizer for manufacturing；In addition, sodium metasilicate also can be widely used in cardboard, carton, welding rod, painting as adhesive
The manufacture such as material.
Liquid sodium silicate is colourless, slightly colored transparent or semitransparent viscous liquid.Wherein SiO2And Na2O mol ratio
Decide the modulus n of sodium metasilicate, modulus is the composition for showing sodium metasilicate, and modulus is the important parameter of sodium metasilicate, typically 1.5~
3.5 between.Modulus is bigger, and sodium silicate solid is more insoluble in water, and normal-temperature water can dissolve when n is 1, and n needs hot water ability when increasing
Dissolving, needs steam more than 4 atmospheric pressure to dissolve when n is more than 3.Sodium metasilicate modulus is bigger, and silica content is more, silicon
Sour sodium viscosity increase, it is easy to decompose hardening, cohesive force increase, therefore the sodium metasilicate of different moduluses has different use.
There is the low defect of long flow path, modulus in existing liquid silicic acid process for producing sodium, therefore a kind of technique of assistant officer's need is simple, energy
Consume the liquid silicic acid process for producing sodium of small high mode.
The content of the invention
In order to solve above-mentioned problems of the prior art, the present invention provides a kind of simple to operate, modulus high liquid
The production method of sodium metasilicate.
The preparation method for the liquid sodium silicate that the present invention is provided, it comprises the steps：
（1）Quartz sand and mass fraction 20-30% sodium hydrate aqueous solution are added in reactor, stirs, are decompressed to 1.8-
2MPa, react 2-7 hour at 160-180 DEG C of temperature, filter；
（2）White carbon is added into filtrate；
（3）2-3 hours are incubated at 160-180 DEG C, filtering obtains liquid sodium silicate.
The white carbon added according to production method as described above is the 65-70% of quartz sand weight.
According to production method as described above, the mass ratio of quartz sand and sodium hydroxide is 1:1.2-1.5.
The present invention by supplementing addition white carbon during the course of the reaction, and the modulus that can control the obtained sodium metasilicate of adjustment is
3.1-3.4, the method for the invention is a kind of production method of high mode liquid sodium silicate simple to operate, it is adaptable to work
Industry metaplasia is produced.
