Abstract
The present invention discloses a modification method of sodium silicate. Liquid sodium silicate is arranged in a container or a pipeline. A rotary magnetic field is additionally arranged outside the container or the pipeline. The rotating speed of the rotary magnetic field ranges from 1200 rpm to 1700 rpm, the strength of the magnetic field ranges from 0.01T to 0.08T, the magnetizing time ranges from 30 minutes to 50 minutes, and thus, the magnetizing modification of the liquid sodium silicate is accomplished. The present invention is used, when the module of the liquid sodium silicate ranges from 2.2 to 2.6, the density ranges from 1.3cm< 3 > (20 DEG C) to 1.4cm< 3 > (20 DEG C). When the water washing quartz sand is 100 percent, the sodium silicate ranges from two percent to four percent, the sodium fluorosilicate (a powder form) ranges from 10 percent to 15 percent, and the sodium silicate with the magnetizing modification through the rotary magnetic field is placed with 24 hours, the tensile strength is high; compared with sodium silicate which has no magnetizing modification treatment and has the same proportion, the tensile strength improves by 30 percent to 100 percent. The strength of the magnetic field of the present invention ranges from 0.01 to 0.08 T. Compared with the traditionally strong magnetic field of 1T, the device cost is low, and the energy consumption is low.
Description
Technical field
The present invention relates to the method that a kind of elimination water glass " wears out ", more particularly relate to a kind of method that " wears out " by magnetic field elimination water glass.
Background technology
Water glass is the general name of various silicate (water glass, potassium silicate, the lithium silicate etc.) aqueous solution, and the general formula that chemistry is expressed is M
2OmSiO
2NH
2O, wherein M is Na
+, K

2The mutual ratio of three constituent quality of O.Sodium silicate is a water glass the most frequently used in the Foundry Production, and chemical expression is Na
2OmSiO
2NH
2O, from structure analysis is the mixing solutions of many sodium polysilicates, they are among the running balance, but in the seasoning process, have micelle to generate in the solution, the polymerization degree generation disproportionation of sodium polysilicate is described, produce polycondensation product, cause the water glass viscosity degradation, surface tension increases, cohesive strength reduces, and this phenomenon is commonly called as " wearing out " of water glass.Eliminate " wearing out " phenomenon of water glass, just intake in the water glass system that must " wear out " to makes the polycondensation product depolymerization.It is to eliminate the water glass a kind of effective ways of phenomenon that " wear out " that the magnetic field modification is handled, the main at present permanent magnetic field that adopts, also can adopt electromagnetic field to set up standing field in the pipeline outside of delivering liquid water glass, carrying out magnetization modification when water glass is flowed through pipeline handles, the needed magneticstrength of this magnetization modification treatment process is bigger, about about 1T, apparatus expensive, energy consumption is bigger.
Summary of the invention
