Description

Reactor for constant Muscovitum cladding operation solid-to-liquid ratio

Technical field

This utility model belongs to Muscovitum processing technique field, relate to a kind of for constant Muscovitum cladding operation solid-to-liquid ratio anti- Answer device.

Background technology

Mica titanium nacreous material is with splitting as substrate, superscribes transparent or relatively transparent at smooth mica surface The titanium dioxide of high index of refraction and the thin layer of ferrum oxide composition.When fiber-optic illuminated to time on mica sheet, mica sheet is just as transparent Small mirror, some light reflects away, part fiber by refraction in the way of transmissive.It is refracted to next through the light gone On individual interface, there is again secondary partially reflective and fractional transmission, continue successively.Known by physical optics, at two The light of reflective surface can interact, and the result of interaction depends on the factors such as phase contrast, angle of incidence, refractive index, from And form the pearly-lustre phenomenon interfering feature.

In encapsulation process, it is common that by Muscovitum and TiCl₄、FeCl₃Solution mixes, and acid adding adds alkali regulation pH value, makes TiCl₄And FeCl₃Change in TiCl₂And Fe₂O₃, it is wrapped in outside Muscovitum, reaches covered effect.Due to the addition of acid-base solution, Causing solid-to-liquid ratio to change, response speed changes the most therewith, and cladding can be uneven, thus affects the quality of Muscovitum.

Chinese patent literature disclose a kind of single coating cobalt titanate green/nacreous mica composite pigment preparation method [application number: 201310474467.5], use the sedimentation method, with pretreatment Muscovitum as substrate, be configured to Muscovitum slurry with deionized water dispersion Muscovitum, Add the acidifying of a small amount of hydrochloric acid, under stirring at 80 DEG C, be slowly added dropwise TiCl₄Acid solution and the mixed solution of soluble cobalt, with Time dropping sodium hydroxide solution, drip complete regulation pH to 9, ripening, filtration washing is dried, 1000 DEG C calcine 2h obtain yellowish green Color composite pigment.Composite pigment surface is nano grade titanium cobalt green particle, and uniform in mica surface cladding densification, clad ratio is to multiple Lightness and the form and aspect of closing pigment have an impact.When material molar ratio Co/Ti >=2, composite pigment surface spinel-type cobalt titanate green Characteristic diffraction peak is notable.The Muscovitum covered effect of different-grain diameter is different, and particle diameter 20-100 μm Muscovitum is the cobalt titanate green of substrate cladding The glittering pearl effect of composite pigment is notable.This is a kind of novel high-performance mica-based yellow green pearly-lustre composite pigment, and performance is excellent In common nacreous mica pigment, and preparation technology is simple.

But said method " is adding the acidifying of a small amount of hydrochloric acid, under stirring at 80 DEG C, is being slowly added dropwise TiCl₄Acid solution and The mixed solution of soluble cobalt, is simultaneously added dropwise sodium hydroxide solution, drips complete regulation pH to 9 " the most do not solve solid-to-liquid ratio The problem changed, causes cladding process to be also unable to reach constant solid-to-liquid ratio.
