Titanium Dioxide Introduction:
The scientific name of titanium dioxide is titanium dioxide, which has excellent white properties, high hiding power and high discoloration power. It is widely used in ink, paper, coating, paint and other industries, and enjoys the reputation of "the king of white". An important reason for its application in plastic products is that titanium dioxide can determine the appearance of light-colored or white plastic products. Of course, titanium dioxide has many other benefits to plastics, such as improving the heat resistance, light resistance, and weather resistance of plastic products, protecting plastic products from UV light, and improving the mechanical and electrical properties of plastic products. Titanium dioxide is used in almost all thermosetting and thermoplastic plastics. They can be mixed with resin dry powders and plasticizer-containing liquids. The dosage is generally about 3-5%. Polyolefins (mainly low density) Polyethylene), polystyrene, ABS, polyvinyl chloride and so on.
Titania used in Plastic:
In the plastic industry, there are four major indicators for determining the quality of titanium dioxide-hiding power, dispersibility, weather resistance and whiteness. The better the hiding power of titanium white, the thinner and lighter the plastic products produced; the dispersibility affects the production cost of plastic products, the better the dispersion of titanium dioxide, the higher the smoothness and brightness of plastic products; it has good weather resistance Titanium dioxide is indispensable for outdoor plastic products and plastic doors and windows.
In the production process of plastic color masterbatches, the whiteness of titanium dioxide is also an important quality index. Plastic color masterbatches are a highly concentrated and efficient color configuration product, that is, the pigment is evenly distributed in the carrier resin at an extraordinary concentration. And form particles of a certain size. It is mainly composed of a core layer (pigment), a coupling layer (coupling agent or surfactant), a dispersion layer (lubricant or dispersant), and a mixing layer (carrier resin). It is used as a dye in plastics. It is widely used in the production of plastic products such as blown film, injection molding, hot pressing, injection molding, etc. The color masterbatch has superior coloring effect, convenient use, energy saving, and no dust and sewage during use, so it is favored by users. Color masterbatches are used as industrial raw materials, and their performance is usually shown in subsequent product applications (such as blown film or injection molding). Therefore, the performance of titanium white in color particles is mainly reflected in the application process of color masterbatches. Titanium dioxide's coloring ability, dispersibility, processability, and whiteness all have a significant impact on the application of color masterbatches. It is logical that the particle size distribution of titanium dioxide is inevitable.
