Background technique
Colloidal solution refers to that a certain size solid particulate medicament or high-molecular compound are dispersed in formed in solvent
Solution.For its particle generally between 1 ~ 100 nanometer, most of dispersion matchmaker is water, and minority is non-aqueous solvent.Solid particle is with more points
Sub- aggregation (colloidal solid) is scattered in solvent, constitutes multiphase uneven dispersion system (lyophoby glue) high-molecular compound with list
Molecular forms are scattered in solvent, are constituted single phase homogeneous dispersion and are drawn (lyophily glue).This kind of solution has its special property, it
Both it is different from low molecule disperse system -- true solution (dispersed phase particle is less than 1 nanometer), also different from thick disperse system -- suspension (point
Dephasing particle is greater than 100 nanometers).Silica solution category colloidal solution is odorless, nontoxic.It is widely used in ceramics, storage battery, papermaking,
The fields such as heat-resisting material and hot investment casting.It is fine and close and harder that silica solution water resistance, heat resistance can be substantially better than organic coating film,
Do not generate electrostatic, various dust difficulty adherency in air.
Currently, traditional silica solution mostly uses mixing, allotment or simple synthetic method preparation, such producer
Not only the technological process of production is more for formula, the time is long, production pollution is big, but also existing equipment is cumbersome and inefficiency, needs mating
Tankage it is too many.More importantly: since equipment is simple, the degree of automation is low, the silica sol granule prepared is small, big
It is small it is uneven, concentration is relatively low, lead to that product yield is low, index is unqualified or even thickness of silica gel is not achieved 30%, and can not
