physical
1) the relative density
In the commonly used white pigment, titanium dioxide minimum relative density, the same quality of white pigment, tio2 surface area of the largest, highest pigment volume.[1]
2) melting point and boiling point
Due to the sharp titanium type under the high temperature will be transformed into rutile type, so sharp titanium type titanium dioxide melting point and boiling point is actually not exist.Only rutile type titanium dioxide has a melting point and boiling point, rutile type titanium dioxide melting point is 1850 ℃, the melting point of (1830 + 15 ℃ in air and oxygen enrichment in the melting point is 1879 ℃, melting point is associated with the purity of titanium dioxide.The boiling point of rutile type titanium dioxide for (3200 + 300 ℃), titanium dioxide under the high temperature slightly volatile.[1]
3) the dielectric constant
As a result of the titanium dioxide high dielectric constant, so it has excellent electrical performance.In some physical properties of titanium dioxide, want to consider the crystallization direction of titanium dioxide crystals.Sharp titanium type titanium dioxide dielectric constant is low, only 48.[1]
4) conductivity
Titanium dioxide has the performance of the semiconductor, its conductivity with temperature rise and increased rapidly, but also very sensitive to hypoxia.Dielectric constant and the semiconductor properties of rutile type titanium dioxide is very important for the electronics industry, can make use of the nature of the production of ceramic capacitors and other electronic components.[1]
5) hardness
According to mohs hardness 10-point scale, rutile type titanium dioxide is 6 ~ 6.5, sharp titanium type titanium dioxide is 5.5 ~ 6.0, therefore in the chemical fiber mat to avoid wear jet holes and use sharp titanium type.
6) hygroscopic
Although there are hydrophilic titanium dioxide, but its hygroscopicity is not too strong, rutile type a sharp titanium type for small.Hygroscopicity of titanium dioxide and its surface area has a certain relationship, the size of the large surface area, high hygroscopicity, also related to the surface treatment and the nature.
7) thermal stability
Titanium dioxide is thermal stability good material.
8) particle size
Titanium pigment particle size distribution is a comprehensive indicator, it seriously affect the titanium dioxide pigment and product application performance, therefore, for the covering power and dispersion of the discussion can be directly from the particle size distribution were analyzed.
The influencing factors of titanium dioxide particle size distribution is relatively complex, the first is hydrolysis the size of the original size, through the control and regulation of hydrolysis process conditions, make the original particle size within a certain range.Followed by calcination temperature, metatitanic acid in the process of calcination, particle through a crystal type conversion period and growth period, and control the suitable temperature, that growth particles within a certain range.Finally is the product of crushing, usually on Raymond mill and analyzer speed regulation, control the quality of grinding and other crushing equipment can be used, for example: universal mill, jet mill and hammer mill plant.
crystal

Crystal morphology: there are three kinds of titanium dioxide in nature rutile type, sharp titanium and titanium plate.Titanium plate type belong to orthorhombic system, crystal type that is not stable, in more than 650 ℃, the converted into rutile type, so there is no practical value in industry.Sharp titanium type is stable at room temperature, but at high temperatures to rutile type.It into strength depending on the manufacturing methods and calcination process is associated with inhibition or promoter etc. Performance verification

1, the titanium white pigment on the properties of coating contrast ratio
Cover of coating performance is the most directly reflect the performance of white pigment and the key indicators, and other components in the coating conditions under the premise of the same, the stronger the paint covering power, show that performance of paint to cover the stronger.
2, titanium white pigment on the absorption of ultraviolet shielding performance
The GR titanium white pigment composite with rutile titanium dioxide (rutile type) (R818) water with 0.2% of the suspension, the ultrasonic dispersion after 20 minutes, sampling in 72 type ultraviolet and visible spectrophotometer testing its light transmittance (see table 4), in order to judge the product to absorb ultraviolet light.
Titanium dioxide pigment, rutile titanium dioxide respectively with suspension of water for each wavelength of monochromatic light transmittance and rule, to less than 400 nm wavelength ultraviolet transmittance are extremely low, with the increase of the incident wavelength, suspension of light transmittance increase, has reached more than 40% to 700 nm.Due to the difference of suspension transmittance can be approximately regarded as solid material itself factors, as a result, therefore, that titanium white pigment compared with rutile titanium dioxide, has the very strong absorption to uv light shielding effect.
Rutile titanium dioxide with the absorption of uv shielding effect is the best stability and good chemical resistance, resistance to pulverization and discoloration resistance reflected, the performance of titanium dioxide pigments present similar optical properties shows its light stability and so on also have resistance to aging performance.
As can be seen through the above two experiments in titanium dioxide pigments used in coating system is available with titanium dioxide performance of the same or similar;Titanium dioxide pigment can be widely used in coating system, improve the performance of the coating, greatly reduce the material cost.
