Titanium white powder so high price coating enterprises can appropriately add silicon micro-powder.

In the face of the rapid rise of
titanium dioxide
in 2016, many giants have raised prices, from 500, 700 shout to 1000 yuan / ton, and even a research analysis said that the price of titanium dioxide in 2017 is expected to exceed 20,000 yuan / ton. Now it is not easy to get through the most difficult period, but the word "up" does not seem to stop, in the face of environmental protection policies, the surge in raw materials,
paint enterprises
unknowingly into the 2017 "glacial period." Faced with the situation of titanium dioxide so rising,
coatings
enterprises can choose to appropriately add silicon micro-powder, with silicon micro-powder part instead of titanium dioxide, in order to reduce costs?
titanium dioxide powerful coating raw materials accounted for
on the one hand, we can not deny the position of titanium dioxide in the coating. Based on pigment grade titanium dioxide has a high refractive rate, strong color dissipation, large cover force, good dispersion, good whiteness, non-toxic, physical and chemical properties are stable, and has excellent optical, electrical properties, so its use is very wide, in the application of coatings occupies a pivotal position.
The use of titanium white can greatly reduce the amount of pigments in the entire coating, while the paint made of bright colors, not easy to yellow, light, heat, wear, weather, alkali, sulfur, acid resistance. Titanium white dosing accounts for more than 90% of the total amount of paint pigments, accounting for more than 95% of the paint white pigments. It accounts for 10% to 25% of the raw material cost of coatings.
is similar to titanium dioxide
on the other hand, silicon micron and titanium dioxide have structural similarities and can partially replace titanium dioxide.
Silicone micropow powder is a micro-powder processed by a combination of processes such as natural quartz (SiO2) or molten quartz (natural quartz melted at high temperatures, cooled amorphous SiO2) by crushing, ball grinding (or vibration, airflow grinding), flotation, acid washing purification, high purity water treatment, etc. It has the advantages of excellent dielectric performance, low thermal expansion coefficient, high thermal conductivity and good suspension performance.
application of silicon micro powder in coatings
(1) silicon micro powder has good stability and has been playing an important role in coating fillers. In the coating industry, the particle size, whiteness, hardness, suspension, dispersion, low oil absorption and high resistivity of silicon micro-powder can improve the corrosion resistance, wear resistance, insulation, high temperature performance of coatings.
performance of several coatings commonly used fillers is . (2) Silicon micro-powder in the coating as a functional filler, filling capacity, reduce costs. Shielding anti-light inhibitors, quartz (silicon dioxide), can replace some of the expensive titanium dioxide used in coatings,
paint
and reduce production costs. By adding silicon micro-powder to the flame retardant insulation coating, the tentacle performance of the coating is improved, the coating has the characteristics of uniform coating, no cracks and short curing time and low cost.
(3) silicon micro-powder non-toxic tasteless non-polluting, does not contain organic pollution, low metal content. It can improve the UV resistance of the coating and has a good insulation effect. In the non-toxic epoxy toughening coating, silicon micro-powder is added to the epoxy resin, and a non-toxic epoxy toughening coating with anti-corrosion function is developed, which overcomes the defects and deficiencies of the existing coating brushing and spraying at low temperatures.
(4) grinding time is short, strong adhesion, dry fast. Used in the preparation of matching paint, primer, rust-proof paint, etc. (addition amount 6-15%) not only play the role of filling capacity, but also for improving paint fineness, leveling performance, paint film hardness, shorten paint grinding time and paint water resistance, rust prevention, anti-corrosion performance and pigment dispersion, paint storage stability and other effects are significant.
(5) With the growing prosperity of the construction market, the amount of silicon micro-powder also increased, and the ultra-fine and modified silicon micro-powder also put forward higher requirements.
of the coating grade silicon micro powder: . Conclusion:
With the pressure of environmental protection policies, the rise of raw material prices, coupled with China's rich quartz resources, silicon micro-powder applications in coatings have attractive market prospects and broad development space.
