How do consumers identify and choose authentic rutile titanium dioxide? Many people responded that they bought unqualified rutile titanium dioxide on the market, not only the brightness is not as good as before, but the coverage strength is also greatly reduced.

Rutile titanium dioxide is widely used in coatings, plastics, rubber, ink and other industries. It can achieve the same technical performance as titanium dioxide, greatly reducing the cost of raw materials. There are a lot of fake rutile titanium dioxide on the market, which will cause the precipitation of white matter in plastic processing, and there is a lot of calcium powder mixed in it. In order to adjust the oil absorption change caused by adding calcium powder, wax powder was added inside, which deceived many consumers. So how to identify the true and false of rutile titanium dioxide?

1. Chemical method:

1. Add light calcium or heavy calcium to dilute sulfuric acid or hydrochloric acid: there will be air bubbles to make clear stone water turbid, because calcium carbonate will react with acid to generate carbon dioxide;

2. Add lithopone to dilute sulfuric acid or hydrochloric acid, which smells like rotten eggs;

3. Make latex paint, add iron red, the color is darker, indicating that the poor hiding power is fake or the quality of titanium dioxide is poor.

2. Physical method:

1. The simple method is to compare the feel, the fake titanium dioxide is slippery, and the real titanium dioxide is awkward;

2. Washing and titanium dioxide stains on hands are easy to wash off, but really not easy to wash off;

3. Take a cup of water and put in titanium dioxide. What floats up is true, what settles down is false.

After understanding the method of distinguishing the authenticity of rutile titanium dioxide, let's look at how to choose:

1. Hiding power: Rutile titanium dioxide can strongly scatter or refract light. If there is enough titanium dioxide in the plastic product, all the light irradiated on its surface will be reflected, and the product will have good hiding power.

2. The whiteness of titanium dioxide is: it can effectively scatter visible light and endow the product with whiteness. Generally, different plastics have their own colors, so the whiteness is obviously different. Therefore, the whiteness of various titanium dioxide should be compared with the whiteness of the same plastic.

3. Dispersion: It has an important influence on the application performance of rutile titanium dioxide in plastics. Generally speaking, the finer the particles, the higher the tinting power and the stronger the hiding power, which is due to the larger specific surface area of refined titanium dioxide and the enhanced light scattering.
