Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and image 3 As shown, a rapid neutralization reaction device for mica coating operation includes a reactor 2 with a stirring mechanism 1, and the reactor 2 is provided with an atomized feed that can inject a gas-liquid mixture into the reactor 2. Mechanism 3, the inner wall of the reaction kettle 2 is also fixed with a turbulence mechanism 4 that can collide with the liquid when the liquid in the reaction kettle 2 flows, so as to change the flow direction of the liquid.

[0025] Using TiCl 4 When the solution is used to modify and coat mica, it is necessary to add HCl solution and NaOH solution to adjust the pH value, so as to stabilize the pH during the coating process, so as to achieve the uniformity of coating. When adjusting the pH value with HCl solution or NaOH solution, if the neutralization process ...

Abstract

The invention belongs to the field of technologies for processing mica, and relates to a quick neutralization reaction device for mica coating operation. The neutralization reaction device comprises a reaction kettle. The reaction kettle is provided with a stirring mechanism, an atomization feeding mechanism capable of injecting gas and liquid mixtures into the reaction kettle is arranged in the reaction kettle, and a turbulence mechanism is further fixed to the inner wall of the reaction kettle and can be collided with liquid when the liquid in the reaction kettle flows, so that the flow direction of the liquid can be changed. The quick neutralization reaction device has the advantages that acid and alkali can be quickly uniformly mixed with reaction liquid when about to be neutralized, accordingly, the acid and the alkali can be quickly neutralized, and the mica coating quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of mica processing, and relates to a rapid neutralization reaction device for mica coating operation. Background technique [0002] Mica titanium pearlescent pigment is based on mica flakes, on the smooth mica surface is wrapped with a thin layer of transparent or relatively transparent high refractive index titanium dioxide and iron oxide. When the optical fiber shines on the mica sheet, the mica sheet is like a small transparent mirror, part of the light is reflected, and part of the optical fiber is transmitted in the form of refraction. The transmitted light is refracted to the next interface, and the second partial reflection and partial transmission occur again, and the sequence continues. It is known from physical optics that the light reflected on two reflective surfaces will interact, and the result of the interaction depends on factors such as phase difference, incident angle, and refractive index...
