Titanium dioxide's journey into the food industry began with its classification as Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA). This status is granted after rigorous scientific evaluation, ensuring that the substance does not pose any significant health risks when used as intended. In Europe, the European Food Safety Authority (EFSA) also approves its use, but with specific guidelines on maximum levels.

Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

  • 6 GUIDELINES TO FOLLOW WHEN CHOOSING AN OIL SEAL

  • The 30% pertains to the metal component, often steel or iron, which forms the backbone of the oil seal. This metallic element gives the seal its structural integrity and strength, allowing it to withstand the pressures within the mechanical systems. It acts as a barrier against wear and tear, ensuring the longevity of the seal and the machinery it protects.
  • Obtaining adequate adhesion of fluoroelastomer compounds to metal inserts is a major consideration in fabrication of shaft seals. Adhesive systems worked out for bisphenol-cured VDF/HFP/TFE elastomers often do not perform adequately for peroxide-curable fluoroelastomers and more base-resistant polymers that contain little or no VDF. The trend toward use of more resistant fluoroelastomers in shaft seals has necessitated considerable effort on compounding and adhesive system development to get adequate bonding of the new materials. Silane-type primers are often used to coat metal inserts; these contain residual active groups such as amine functions that interact with the fluoroelastomer compound to attain good adhesion, especially for VDF/HFP/TFE elastomers. Other adhesive systems, using epoxy compounds or tie-coats, may be necessary for difficult bonding situations.3

  • Moreover, double oil seals are particularly effective in harsh operating conditions, such as extreme temperatures or abrasive environments. The secondary seal provides additional protection against wear and tear, extending the life of the sealing system and reducing maintenance costs.
  • In conclusion, performance spark plug wires are a vital component of any high-performance engine setup. By choosing the right wires and having them installed by a professional, you can unlock your vehicle's full potential and enjoy enhanced performance, improved fuel economy, and a more thrilling driving experience.
  • In conclusion, diesel spark plugs, or glow plugs, are a critical aspect of diesel engine functionality. They are the unseen heroes that facilitate smooth engine operation, especially during cold starts. Understanding their function and importance can help prevent potential issues and ensure your diesel engine performs at its peak. Always opt for reliable, high-quality glow plugs, and maintain a regular maintenance schedule to prolong the life of your engine and enjoy a seamless driving experience.

    2. A locking gasket is a crucial component in many industries, including automotive, aerospace, and manufacturing. This innovative product is designed to provide a secure seal between two surfaces, preventing leaks and ensuring the longevity of the equipment. In this article, we will explore the various applications of locking gaskets and the benefits they offer to industries worldwide.

    4. Moreover, pulley oil seals act as a shield against external elements such as dust, dirt, and water. These contaminants can cause wear and tear on the pulley and the shaft, leading to premature failure if allowed to enter the system. By keeping these particles out, oil seals help maintain the cleanliness of the machinery, enhancing its overall performance and durability.

    12. Performance criteria are established in the oil seal standard to ensure that the seal meets certain performance benchmarks. These criteria may include factors such as maximum pressure, temperature range, and expected lifespan. Manufacturers must test their seals to ensure that they meet these performance criteria before they are sold to customers.
