Embodiment 1

[0062] Embodiment 1: A kind of detection method of the dispersibility of titanium dioxide in water

[0063] The detection method of the dispersibility of titanium dioxide in water of the present invention, it may further comprise the steps:

[0064] A. Preparation of titanium dioxide specific proportion slurry: titanium dioxide specific proportion slurry is prepared according to the following components by weight:

[0065]

[0066]

[0067] B. Weigh m1 g of titanium dioxide specific proportion slurry, filter it with a 325-mesh filter, use the pressure of the water itself to wash during the process, then dry the sieve residue in an oven at 55°C for 15 minutes, and weigh the amount of the sieve residue m2 g;

[0068] C. Using the formula

[0069] Calculated test results, the smaller the test result y value, the better the dispersion performance of titanium dioxide in water.

[0070] The further optimization of the detection method of the dispersibility of titanium dio...

Abstract

The invention aims to solve the technical problem of providing a method for detecting the dispersibility of titanium dioxide in water. The method can be used for accurately, quickly and quantitatively testing the dispersibility of the titanium dioxide in the water. According to the method for detecting the dispersibility of the titanium dioxide in the water, quantitative characterization is carried out on the dispersibility of the titanium dioxide in the water through the steps of preparing titanium dioxide slurry with a specific ratio, weighing the mass of the slurry and the mass of screen residues, calculating a measurement result by using a formula and the like, and grade evaluation on the dispersibility of the titanium dioxide in the water is realized. The premise that the excellent performance of the titanium dioxide in a water-based product is shown is that the titanium dioxide can be well dispersed in the water, so that the method has important significance in research on a detection method of the dispersibility performance of the titanium dioxide in the water.

Description

technical field [0001] The invention belongs to the field of performance detection of titanium dioxide, in particular to a method for detecting the dispersibility of titanium dioxide in water. Background technique [0002] Titanium dioxide is a white pigment with the best performance and the most widely used in the world. Because of its excellent light scattering ability, high whiteness, high chemical stability and good weather resistance, non-toxic, tasteless, and non-irritating to the human body, it is widely used in the coating industry. [0003] However, the premise of whether these excellent properties of titanium dioxide can be displayed in the coating is: whether it can be well dispersed in the coating. Especially in water-based coatings, the wetting and dispersing of titanium dioxide is more difficult, and it is easy to settle and agglomerate, which forces us to pay special attention to the dispersion performance of titanium dioxide in water. [0004] At present, t...
