Titanium Dioxide Application Range for Plastics Expanded

Titanium dioxide for ordinary general-purpose plastics is generally not surface-treated because conventional inorganic titanium dioxide coated with hydrated alumina is used. When the relative humidity is 60%, the adsorption equilibrium water is about 1%. When the plastic is at a high temperature, During the extrusion process, evaporation of water causes pores on the smooth plastic surface. This non-organic coated titanium dioxide is generally subjected to organic surface treatment.

Because the titanium dioxide used in plastics is different from the titanium dioxide used in coatings, the former is in a low-polarity resin and is processed by shearing. The titanium dioxide after organic surface treatment can be better under the appropriate mechanical shear force. Scattered.

The application of titanium dioxide in plastic products, in addition to its high hiding power, high achromatic power and other pigment properties, it can also improve the heat resistance, light resistance and weather resistance of plastic products, and protect plastic products from UV light. Invasion, improve the mechanical properties and electrical properties of plastic products.

Most titanium dioxide particles used in plastics are finer in size. Usually, the particle size of titanium dioxide used for coating is 0.2-0.4 μm, while the particle size of titanium dioxide used in plastics is 0.15-0.3 μm, so that the blue phase can be obtained. Most yellow-phased resins or yellowing resins have a masking effect.

Brief Introduction & Working Principle --Centrifugal Sifter
The screen holder is placed inside the machine. Bulk materials mixed with airflow and atomization pass the Screw Conveyor device, enter the screen holder. The undersize materials are sprayed through the screen cloth and discharged from the outlet under the action of centrifugal force and the cyclone propelling power, which caused by the blade inside the net tube. The oversize material, which can not cross the screen cloth, is discharged from the rough material outlet along the inside surface of the tube.
Cantilevered design and twin screen holder design are available.
*Very smart but large capacity for light materials(such as starch,flour,lime powder,etc.)
*Mesh size should not be higher than 325 mesh
*No oversize end bearings or seals Hinged oversize end door. 
*Easy to remove screen and screen retainer Hygienic design sifting screen. 
*The sifter can be stripped down for cleaning without the need for specialist assistance.
*Full sealing makes this machine dust proof.
*No transmitted vibration.
*Easy to inspect and/or clean No tools required for screen, paddle and screw removal. 

*Sanitary design and fast disassembly without tools
