Problems solved by technology

[0005] However, in the above method, "acidify by adding a small amount of hydrochloric acid, slowly add TiCl dropwise under stirring at 80°C. 4 A mixed solution of acidic solution and soluble cobalt salt, while adding dropwise sodium hydroxide solution, and adjusting the pH to 9" after the dropwise addition did not solve the problem of how to quickly neutralize

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 mica-coated titanium liquid atomization and spraying rapid neutralizer includes a reaction kettle 2 with a stirring mechanism 1, a spray plate 3 is fixed at the bottom of the reaction kettle 2, and the spray The lower surface of the plate 3 is densely covered with spray holes 4, the spray plate 3 is connected to the gas-liquid mixer 5 and the gas-liquid mixer 5 is located outside the reaction kettle 2, and the gas-liquid mixer 5 is also respectively connected to the liquid feed assembly 6 and the gas feed Component7.

[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...

Abstract

The invention belongs to the technical field of mica processing and relates to a rapid neutralizer for atomizing and spraying a titaniferous solution in a mica coating operation. The rapid neutralizer comprises a reaction kettle with a stirring mechanism, wherein a spraying tray is fixed at the bottom of the reaction kettle; spraying holes are densely distributed in the lower surface of the spraying tray; the spraying tray is connected with a gas-liquid mixer and the gas-liquid mixer is positioned outside the reaction kettle; the gas-liquid mixer is also connected with a liquid feeding component and a gas feeding component. According to the rapid neutralizer disclosed by the invention, during acid-base neutralization, atomized liquid can be formed and uniformly enters the reaction kettle, so that acid and alkali are rapidly and uniformly mixed with a reaction solution, and further rapid neutralization is realized.

Description

technical field [0001] The invention belongs to the technical field of mica processing, and relates to a rapid neutralizer for atomizing and spraying titanium liquid in 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 angl...
