The titanium powder in the titanium coil has the following characteristics:
1, relative density
Among the commonly used white pigments, the relative density of titanium dioxide is small. In white pigments of the same quality, the surface area of titanium dioxide is large and the volume of the pigment is high.
2, melting point and boiling point
Because the anatase type transforms into the rutile type at high temperature, the melting point and boiling point of anatase type titanium dioxide are practically non-existent. Only rutile titanium dioxide has a melting point and boiling point. The melting point of rutile titanium dioxide is 1850°C, the melting point in air is (1830±15)°C, and the melting point in oxygen enrichment is 1879°C. The melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium dioxide is (3200±300)°C, and titanium dioxide is slightly volatile at this high temperature.
3, dielectric constant
Because of the high dielectric constant of titanium dioxide, it has excellent electrical properties. When determining certain physical properties of titanium dioxide, the crystal orientation of the titanium dioxide crystal should be considered. The dielectric constant of anatase titanium dioxide is relatively low, only 48.
4, conductivity
The titanium powder in the titanium coil has the properties of a semiconductor. Its electrical conductivity increases with the rise of temperature, and it is also very sensitive to oxygen reduction. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important to the electronics industry, which can be used to produce ceramic capacitors and other electronic components.
5, hardness
According to the Mohs hardness scale of 10 points, rutile titanium dioxide is 6 to 6.5, and anatase titanium dioxide is 5.5 to 6.0. Therefore, anatase is used in chemical fiber matting to prevent wear of the spinneret holes.
Titanium coils are mainly used for heating and cooling of containers. The fixing methods are divided into two types: detachable and non-detachable. This depends on the medium of the material and the corrosion of the titanium pipe, but in the design, it is mainly detachable. The main type is to facilitate the maintenance and cleaning of the titanium tube.
