PRODUCT DESCRIPTION
Adopted unique technology, the product is characterized by excellent whiteness and opacity, symmetrical distribution of grain size, high tinting strength, high hiding power, good performance etc.
Rutile properties:
1) Tio&sub2; Content: 94% min.
2) Specific gravity: 4.1g/cm3
3) pH: 6.5-8.0
4) Oil absorption (g/100g): 19-21
5) Resistance: 85Ω M
6) Retained on 325 mesh: 0.02% max.
Rutile type ( type R) :
Density 4.26g / cm3, refractive index 2.72. R type titanium dioxide has good weather resistance, water resistance and non-yellowing characteristics, but the brightness is not as good as Anatase.
Anatase (type A)
Density of 3.84g / cm3, refractive index of 2.55. A type of titanium dioxide light fastness, intolerant weathering, but the whiteness is better. In recent years, nanoscale ultrafine titanium dioxide (usually 10 ~ 50 nm) has the properties of semiconductor, and has high stability, high transparency, high activity and high dispersibility, non-toxic and color effect.
