Titanium dioxide (TiO2). Titanium dioxide is the most common white pigment used today. As a pigment, titanium dioxide is unique because it combines both high colouring and high opacifying capacity. This is mainly due to its high refractive index (2.7). Furthermore, titanium dioxide is an excellent UV absorber (it is used in sun protective creams). Some typical properties are: density 3.3-4.25 g/cm3; pH of water suspension 3.5-10.5; particle size 8–300 nm; oil absorption 10–45 g/100 g; specific surface area 7–160 m2/g. Most titanium dioxide is produced from the rutile (TiO2) or ilmenite (titanate of ferrous iron). Titanium dioxide can be obtained using different processes.
It is generally more expensive than lithopone and may not be as environmentally friendly It is generally more expensive than lithopone and may not be as environmentally friendlylithopone and titanium dioxide. The production process for TiO2 involves the use of hazardous chemicals, and its disposal can be problematic. Additionally, TiO2 has a tendency to agglomerate, which can affect its performance in certain applications.The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.
51124 bearing. In the aerospace sector, they play a vital role in aircraft landing gears, ensuring safe and smooth takeoffs and landings. Power generation plants utilize them in turbines to manage the massive axial forces generated during energy production. Even in marine applications, they are instrumental in ensuring the efficient functioning of propeller shafts.
bearing 51309. Regular cleaning and inspection are necessary to detect any signs of wear or damage. It is recommended to clean the bearing using a mild solvent and then dry it thoroughly before re-lubrication. The frequency of cleaning and inspection may vary depending on the operating conditions of the equipment, but generally, it is advisable to perform these tasks at least once a year.
- Taper Roller Bearings: Taper roller bearings are designed to support both radial and axial loads by utilizing tapered inner and outer ring raceways. They are capable of handling thrust (axial) and radial loads in a single direction and are commonly used in applications such as automotive wheel hubs, gearboxes, and heavy machinery.
