Masterbatch course What are the requirements for titanium dioxide
Release time：2016/9/23
In the use of titanium dioxide, pay attention to relations with titanium dioxide, plastic raw materials, additives between the points where the choices are the following:
1, good chemical stability
Titanium dioxide can and resins, and various flux mutual integration in the production process, no chemical reaction, fusion and strong, good heat resistance and the like. This shows that the titanium dioxide masterbatch production process does not chemically react with the variety of materials.
2, the temperature is good
When masterbatch and plastic molding process at high temperatures are produced in the production process, which also explains the decomposition of titanium dioxide does not change color in the process of high temperature processing.
3, migration of small
Because plastic products are processed from molding in high temperature environments. During the processing of titanium dioxide does not occur decomposition and chemical reaction, no side can cause the plastic surface color is not enough average.
4, good dispersion
Titanium dioxide dispersed unevenly in the course of processing, the performance will affect the appearance of plastic products; tinting strength of titanium dioxide is relatively poor, this will cause an increase in the amount of titanium dioxide, the cost increase. Titanium-colored in different environments will be very different, so we choose Titanium Dioxide time to pay attention to this. In addition, the size of the titanium dioxide particles also have a relationship with the dispersion, the smaller the particles of titanium dioxide dispersion, the better, the coloring power is also relatively strong.
5, excellent workability
When titanium dioxide having a high melt index in the carrier resin, masterbatch mixing and kneading step in production can proceed smoothly. Good titanium dioxide powder can help accurately added easily by filtering vibration sieve, reduce residues.
Finally, titanium dioxide is also used in food, children's toys produced above, plastic products for electrical, with good electrical insulating effect.
