Abstract

The invention provides a rutile titanium dioxide salt accelerator and application thereof, belonging to the technical field of rutile titanium dioxide production. The salt treatment agent includes one or more of zinc salt, potassium salt, phosphoric acid / phosphate, magnesium salt, barium salt and lithium salt. In the implementation process, the present invention obtains the claimed salt treatment agent by studying the components of the rutile titanium dioxide salt treatment agent. By changing the type of salt treatment agent and the content of various salt treatment agents, the calcining temperature is reduced, and the The conversion rate of rutile crystal form, and found that the addition order of salt treatment agents will affect the whiteness and anti-aging performance of rutile titanium dioxide, and the whiteness of rutile titanium dioxide is improved by controlling the addition order of various salt treatment agents during the preparation process and weather resistance.

Description

technical field

[0001] The invention belongs to the technical field of rutile titanium dioxide production, and in particular relates to a rutile titanium dioxide salt accelerator and an application thereof. Background technique

[0002] Titanium dioxide in nature exists in three crystal forms: brookite, anatase and rutile. The property state of plate titanium dioxide is unstable; the anatase titanium dioxide has a high reflectivity to ultraviolet rays, and it is easy to excite electronic energy band transitions to generate photogenerated charge carriers, which in turn promotes the occurrence of photocatalytic reactions. This feature is widely used in air purification , wastewater degradation treatment, etc.; rutile titanium dioxide is the most stable crystal form, has more stable physical and chemical properties and excellent pigment performance, and is usually used as an important inorganic chemical raw material in the production process of paint, food, cosmetics, etc. Agr...
