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.

  • It is a non-tacky silicone-rubber tape that is used for adhesion or protection of materials. Rubber tapes are used in many areas like providing protection and electrical insulation layer for different equipment like cables and electrical joints. Rubber tape is resistant to heat, weather and sunlight. In solar module manufacturing, it is widely used as a sealant due to its mainly good mechanical properties, impact resistance, high adhesion properties, and relatively cheap cost. It is used during manufacturing, installation and normal operation of PV modules for mounting, adhesion and sealing requirements for modules.   Advantages and disadvantages of using rubber tape edge sealant Rubber sealing tape meets the demand of a wide variety of difficult sealing applications. It can be used for oversealing of an existing joint or penetration, normal sealing applications which are typically done with a gasket, or liquid sealant/adhesive. The rubber sealant tape is flexible, durable, and abrasion resistant. It is also conformable which helps create an effective seal over contours, edges rivets, and edges. Rubber tape also has good moisture resistance and as an edge sealant primarily prevents moisture ingress and protects components besides insulation splices and connections in electrical components. The rubber tape is susceptible to cuts and abrasion as it has low tear resistance. This disadvantage is increased because the rubber tape is wrapped while stretched, and stays under internal tension. Yet, these same properties, make tape removal when needed clean and easy.

  • No matter what kind of control box you’re designing, it’s important to follow the established best practices of control box design . Some of the core principles of designing a great control box are as follows:

  • In addition to providing protection, car harness tape also helps to organize and secure the wiring harnesses in your vehicle. By neatly wrapping the tape around the harnesses, you can prevent them from getting tangled or damaged during routine maintenance or repairs.


  • 6. Trim Excess Tape Use a sharp utility knife or scissors to trim any excess tape from the edges.
  • The film then passes through a cooling system before being wound onto large rolls. The adhesive layer is applied on one side of the film, usually a rubber-based or acrylic adhesive, which provides the necessary stickiness without compromising the electrical insulation. The final step is slitting the large rolls into narrower widths suitable for different applications, followed by packaging and quality control checks.
  • One of the most notable features of Flex Tape, including the white variant, is its waterproof characteristics. This is especially beneficial for outdoor use or in areas prone to moisture exposure. Whether you need to patch a leaky roof, seal a crack in a pipe, or repair pool liners, Flex Tape provides a reliable solution that stands the test of time. Its powerful adhesive ensures that once it’s applied, it stays put, eliminating the need for constant maintenance or reapplication.
