Anatase, known for its excellent photocatalytic activity, is primarily used in the production of advanced materials and environmental protection products. Its unique ability to break down pollutants under sunlight makes it an ideal choice for air purification and self-cleaning surfaces. On the other hand, Rutile, with its superior opacity and durability, is more commonly used in the coatings, plastics, and paper industries, providing a white pigment and UV protection.

In a 2022 study published in the Journal of Hazardous Materials, scientists wanted to examine the effects of titanium dioxide as a food additive on atherosclerosis in mice. (Atherosclerosis refers to a hardening of the arteries.) Researchers fed mice 40 mg/kg of the food additive every day for 4 months, and found that it not only altered gut microbiota but also led to a significantly increased atherosclerotic lesion area, especially in animals that consumed a high-choline western diet (HCD).

Background and overview

Globally, Iron Oxide is the second largest inorganic pigment after Titanium Dioxide and the first largest color inorganic pigment. Iron oxide pigments mainly include iron oxide red, yellow, black and brown with iron oxide as the basic material. Iron oxide yellow, also known as hydroxyl iron oxide (FeOOH), will be dehydrated and decomposed into red at about 177 ℃, so the application of ordinary iron yellow pigment in high-temperature occasions such as plastic processing and baking coatings is limited. Iron oxide yellow pigment can improve its temperature resistance through surface coating, so as to expand the application field of iron oxide yellow pigment.

The chemical formula of iron oxide yellow (also known as hydroxyl iron) is α- Fe2O3 · H2O or α- FeOOH, with needle like structure and yellow powder, is a kind of particle size less than 0.1 μ m. Iron series pigment with good dispersibility in transparent medium has strong coloring power, high covering power, insoluble in alkali and slightly soluble in ACID. Synthetic iron oxide yellow has the characteristics of light resistance, good dispersion, non-toxic, tasteless and difficult to be absorbed by human body. It is widely used in coatings, plastics, ink and pharmaceutical industry.

Physical and chemical properties and structure

1. Iron oxide yellow pigment has acid and alkali resistance, resistance to general weak and dilute acids, and is very stable in alkaline solution of any concentration.

2. Iron oxide yellow pigment has certain light resistance, heat resistance and weather resistance. Its coating color is durable and can keep the coating from being damaged in light. Iron oxide yellow pigment is stable in a certain temperature range, but beyond the limit temperature, its color begins to change, and the degree of change is more significant with the increase of temperature. Iron oxide yellow pigment is not affected by cold, heat, dry and wet weather conditions.

3. Iron oxide yellow pigment is very stable in any ambient atmosphere (such as gases containing H 2S, Co, so 2, HCl, no, etc.). And resistant to pollution, water, oil and solvent penetration, insoluble in water, mineral oil or vegetable oil.

4. Iron oxide yellow pigment has strong coloring power and high hiding power. With the decrease of pigment particle size, its coloring power is stronger.

application

Nano iron oxide yellow has the characteristics of acid resistance, alkali resistance, non toxicity and low price. It is widely used in coatings, plastics and rubber. The particle size of nano iron yellow is less than 100 nm, which makes it have some unique characteristics. When light shines on its surface, transmission and diffraction will occur, showing transparent yellow, and can strongly absorb ultraviolet rays, Therefore, it can be used as a functional pigment for the surface paint of high-grade cars, precision instruments, bicycles, motorcycles, cosmetics, food, drugs and other coloring additives.

  • The 40x52x7 oil seal finds extensive use in automotive, industrial, and hydraulic applications where the prevention of oil leakage and protection against dust or debris ingress is paramount
  • Car engine oil seal is a crucial component in any vehicle's engine system. It plays a vital role in preventing oil leaks and maintaining proper lubrication of the engine components. In this article, we will discuss the importance of car engine oil seals, their functions, and the consequences of a failing oil seal.

  • When installing a new E6TC spark plug, it is important to ensure that it is properly gapped. The gap refers to the distance between the central electrode and the ground electrode and can affect the efficiency of the spark plug. A larger gap may result in a weaker spark, while a smaller gap can cause misfiring and engine performance issues. Refer to the manufacturer's specifications for the correct gap size for your vehicle or equipment.

  • Applying Oil Seal Dimensions in Real-World Scenarios

  • Shaft seals, dirt seals, grease seals, lip seals, and many other names are only a few of the many names given to oil seals. They are simple components used in rotary shaft machinery to keep oil from leaking and impurities like dust, dirt, and water out. However, an oil seal’s most crucial role is to safeguard all ball, sleeve, and roller bearing types found in rotating shafts. Additionally, the seals stop blending two fluids that shouldn’t mix, such as water and oil.

  • Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.

  • Moreover, the BR7EF spark plug's superior insulation material withstands high temperatures and pressures within the combustion chamber, reducing the risk of misfires
  • In conclusion, oil seals are essential components in the automotive industry, providing a reliable barrier against oil leakage and contamination. The dimensions of an oil seal, such as 50 * 72 * 10, play a key role in determining its fit and effectiveness in various applications. By selecting the right seal and ensuring proper installation, machinery and equipment can operate smoothly and efficiently, with minimal risk of oil-related issues.
  • In addition to visual inspections and resistance testing, there are other methods that can be used to test spark plug wires. One such method is the spark tester, which can be used to check for the presence of a spark when the ignition is turned on. Simply attach the tester to the end of the spark plug wire and crank the engine. If a spark is present, then the wire is functioning properly. If no spark is detected, then the wire may need to be replaced.
