Titanium dioxide
It is based on the experience of vitriol (Sulfuric acid) production process,combining many innovative researches such as inorganic coating,organic treatment,salt treatment,calcination control,hydrolysis,product applications and so on.
1 The production process:
The production process adopts the advanced hue and size control technology,zirconium,silicon,aluminum,phosphorus multiple inorganic coating and new organic processing technology,it is a new generation of high-end and general-purpose type (water-biase) rutile titanium dioxide,applicable to a variety of architectural coatings, industrial paint,anticorrosive paint, ink, powder coatings and so on.
2 Application features:
2.1 Blue bottom and high whiteness:
Its particle size is small and uniform,scatter the blue light more effectively than the large size, therefor it has a bluer bottom and more excellent whiteness.
2.2 High weather resistance:
It has a higher rutile content,intact crystal lattice,adequate filler,adopts adequate zirconium,silicon,aluminum,phosphorus multiple inorganic coating and organic processing,can ensure high weather-resistance.
2.3 Good dispersion:
it reduces the contact between the tio2 particles through the special inorganic surface treatment and organic surface treatment ,make the R-258 have a good dispersion in the application process,so it has a good wettability,easy to grind.
2.4 Low oil absorption:
its low oil absorption property make it have good mobility in the paint and ink
area application,help to save the cost.
2.5 Low wear:
R-258 applicates special hydrolysis,salt processing, calcined and surface treatment,the particles are relatively soft and easy to grind,so the wear is low.
