Silicon dioxide can be used as a white pigment filler. This includes plastic profiles, color masterbatchs, paints, emulsion and powder paints, papermaking, cosmetics, chemical fiber, and more. This should be used in both the solvent and water systems. Due to differences in the applications and systems of organic coatings, additional criteria must be met. Traditional TMP/peg cannot be used to meet these requirements. It can also have adverse effects like the bubble problem. Different USES for titanium dioxide require that different organic treatment agents be used in order to obtain a satisfactory effect on the application. Other requirements for titanium dioxide processing are required, as well as different USES.
For plastics, titanium dioxide requirements
1. Lubrication with high viscosity/extrusion
The cost of products made from color-filled plastics has been reduced to improve their strength and durability. As a result, it is easier to make plastic products’ surfaces rougher and less lubricious. For example, the common color masterbatch in the plastic industry is made from extrusion and granulations of titanium dioxide. It then gets kneaded at high heat using an organic resin having a low density like high-pressure Polyethylene or polyethylene wax as the carrier. In order to produce white masterbatch with high resin compatibility, you must use as few carrier resins as possible in order to moisten the titanium dioxide. The surface wettability of titanium dioxide for masterbatches production must be high. If it is not, it can be difficult to granulate or disperse unevenly during use.
2. Temperate/weather resistance
Plastic products of any kind, regardless of type, must first be in the high temperature melt state. The temperature at which plastic products can be processed is 200 degrees or higher. The temperature at which some plastic components can decompose will cause porosity and pigment migration, which could seriously affect product surface quality and strength. The formula should have excellent temperature resistance. Also, most plastic products such as plastic film and electrical appliances that are exposed to sunlight must be UV resistant. A lead stabilizer will usually be added when processing PVC plastic products. It is possible for this type of stabilizer to react with other active chemical substances at high temperature and create black substances. This is known as the “leadblack” problem in plastic manufacturing. For the lead stabilizer, it is essential that the organic coating agent used on titanium dioxide’s surface be inert.
3. Wet powder fluidity/moisture resistance
In plastic products production, more and more factories will employ continuous production lines. For automatic metering, they may also utilize transmission belt or vibration loss sieve equipment. Let’s say that there is a slow flow of titanium dioxide dry particles. It will stick in the transmission belt and plug the screen hole. In this case titanium dioxide can’t be measured accurately or added smoothly, so it could cause damage to plastic products.
