QUALITY REQUIREMENTS FOR PLASTIC PRODUCTS ON TITANIUM DIOXIDE TIO2

Plastics industry used titanium dioxide (TIO2) at the large quantity. 
As titanium dioxide for plastics is different from titanium dioxide for coatings, the former is in low-polarity resin, processed and mixed by shearing force, and the titanium dioxide after organic surface treatment can be better under appropriate mechanical shearing force. scattered.

With the continuous expansion of the application range of plastic products, many external plastic products, such as plastic doors and windows, building materials and other outdoor plastic products, also have high requirements for weather resistance. In addition to the use of rutile titanium dioxide, surface treatment is also required. This surface treatment generally does not add zinc, only silicon, aluminum, zirconium, etc. are added. Silicon has a hydrophilic and dehumidifying effect, which can prevent the formation of pores due to the evaporation of water when the plastic is extruded at high temperature, but the amount of these surface treatment agents is generally not too much.

The quality requirements of plastic products for titanium dioxide are:
1) Hiding power: Titanium dioxide with good covering power produces lighter and thinner plastic products.
2) Whiteness: determines the appearance of light-colored or white plastic products.
3) Dispersibility: It affects the production cost of plastic products. Poorly dispersed titanium dioxide in plastic products will affect the smoothness and brightness of the product.
4) Weather resistance: Plastic products used outdoors and plastic doors and windows must ensure the weather resistance of titanium dioxide.
