Rutile Titanium Dioxide For Paper Making

The easiest way is to compare the feel, fake titanium dioxide is more slippery, real titanium dioxide is more astringent

Water rinse, hands with some titanium dioxide, fake easy to wash off, really not easy to wash off

Take a glass of water, throw titanium dioxide into it, float up for the real, precipitation down for the false (if the product is modified by activation will not work)

Adulterated with light or heavy calcium: add dilute sulfuric acid or hydrochloric acid, there are bubbles can make the clarified lime water cloudy, because calcium carbonate will react with acid to produce carbon dioxide

Adulterated with Lidl powder: add dilute sulfuric acid or hydrochloric acid, with rotten egg smell

Made into latex paint, plus iron red, dark color, indicating poor coverage for the false or very poor quality of titanium dioxide

Project

Using the same PP + 30% GF + 5% PP-G-MAH + 0.5% titanium dioxide, the lower the strength, the more true the titanium dioxide (rutile)

Project

Choose a transparent resin, such as transparent ABS + 0.5% titanium dioxide, measure the light transmission, the lower the light transmission, the more real titanium dioxide
