Introduction of GR Composite Titanium White Pigment
Select inorganic powder as basic raw material (inner nucleus). The inorganic powder has similar outlook structure, the grain-size distribution as well as reaction activity with titanium dioxide. Take TiO2 as coated material, applies a series of high-new techniques, such as modification compound preparation, coating film, powder uniforming and so on, through superfine, hydroxylation transformation of surface and mechanical power chemical action but becomes new compound white pigment. Comparing common titanium dioxide, this GR composite titanium white pigment has almost same or similar functions and properties but at lower price. The new type of composite titanium white pigment has approximate physical and chemical properties thus thus has the properties of titanium dioxide pigment. Used in the coating, may obtain same technical performance as the titanium oxide powder, also lower production cost in great scope. Its production and application of GR compound titaninum white pigment are the effective way to solves shortage of titanium dioxide resources, reduce the environmental pollution and raises utilization ratio of the titanium dioxide.
Characteristic Of Products:
1. Coated equipment and technique reach international advanced level.
2. Surface of composite titanium white pigment appear completely the same properties with crystal TiO2. Thus, it has similar or the same properties as common pure TiO2, such as oil absorption, whiteness, coverage power and others.
3. Comparing with common pure TiO2, our composite titanium white pigment has better particle size distribution, dispersion effect and adaptability
4. Reduce largely production cost than common pure TiO2.
5. There is no pollution during production procedure.
1. GR composite titanium white pigment influence to contact ratio of coatings
Coverage capacity is one of key, direct indexes of coatings standing for its performance. Based on the same ingredient of coatings and conditions, the coverage power of the stronger coatings stand for the coverage power of the stronger pigments. Taking pure titanium dioxide and GR titanium white pigment as pigment, Styrene acrylic latex is fabricated respectively. Experiment description is as table 2 and inspection of contract ratio as table 3

3). The description only is used in test but not as description recommended
From the above table, you may find that used in coating production, GR composite titanium white pigment have similar contract ratio ( stand for coverage ratio ) to common titanium dioxide.
2. GR composite titanium white pigment outstanding functions of shielding and absorbing ultraviolet ray Make up 0.2% suspension solution of respectively TiO2 R818 and GR composite titanium white pigment TR818. Scatter and mix them for 20 minutes by supersonic wave, take sample and test by 72-type spectrophotometer to check light transmittance, by which we may judge absorption effect of solution to ultraviolet ray
