For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.

Lithopone, white powder, relative density: 4.136 ~ 4.39 g / mL, insoluble in water. It is a mixture of zinc sulfide and barium sulfate. Inorganic white pigment, widely used in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene, and white pigments of paints and inks. It is less effective in polyurethane and amino resins and less suitable in fluoroplastics. It is also used for coloring of rubber products, paper, varnish, tarpaulin, leather, watercolor paint, paper, enamel, and the like. Used as a binder in the production of electric beads.

  • A standard oil seal consists of an outer circular metal disk with an inner flexible rubber which is affixed to the metal during vulcanization. The bonded seal has no loose parts to allow leakage of oil or ingress of any contaminants. This kind of seal is more accurate, and can easily be fitted into a smaller space. An example is shown in Figure 2.9.

  • A thick rubber gasket, a seemingly simple yet highly effective component, plays a pivotal role in various industrial applications where sealing and leak prevention are critical. These humble rings of resilience embody the essence of engineering efficiency, providing a robust barrier against liquids, gases, and even extreme temperatures.

  • Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.

  • Take off the gasket from the cover flange or cylinder head , noting how it is attached. Some gaskets have tongues that fit cutouts in the flange; others are stuck to the flange with sealant ; some just fit into the flange groove .

  • When replacing, the PTFE sealing lip of the new oil seal should not be in the same position as the old oil seal. The diameter of the sealing lip should be smaller than the shaft diameter.
  • In electronics and electrical equipment, thin rubber gaskets are used to seal enclosures, control panels, and connectors. They protect sensitive components from dust, moisture, and other contaminants, ensuring the reliability and longevity of the equipment. These gaskets are often made from conductive rubber materials to provide electromagnetic interference (EMI) shielding and grounding.

  • Oil seals are often called grease, fluid, or dirt seals. These seals close spaces between stationary and moving components in mechanical equipment. Oil seals are designed to prevent the escape of lubricant. They also block contaminants from entering machinery. This is especially important in severe environments where heat and foreign objects may be frequently present. They also prevent the mixing of different mediums like lubricating oil and water.

  • The durometer of an oil seal is typically dependent on the material it is made with. Common oil seal materials along with their durometers are as follows:

  • The primary function of an oil seal is to create a tight barrier between two surfaces, one stationary and the other in motion. It achieves this by utilizing a combination of materials, including rubber, plastics, and metals, which are carefully selected for their compatibility with the operating conditions and the fluids being sealed.

  • Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.

  • One essential component of a vehicle's engine that often goes unnoticed is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in the engine's combustion chamber, which ultimately powers the vehicle. While most spark plugs are a standard silver color, there is a particular type known as the black spark plug that has been gaining popularity among car enthusiasts.

  • One of the key advantages of iridium spark plugs is their exceptional ability to withstand extreme temperatures. Iridium, a rare and highly conductive metal, has a melting point that is significantly higher than that of traditional platinum or nickel alloy spark plugs. This means that iridium spark plugs can handle the intense heat generated by modern engines without sacrificing performance or longevity.

  • The valve cover gasket plays a critical role in maintaining the integrity of the engine by preventing oil leaks and maintaining proper lubrication. It ensures that the engine remains free from oil leaks, contributing to its overall efficiency and reliability. A high-quality valve cover gasket is essential for preserving the proper functioning of the engine and protecting it from potential damage due to oil leakage.
