• Therefore, today, they only recommend limiting titanium dioxide inhalation in industries with high dust exposure, such as paper production (11).

• Thirdly, the supplier's pricing and delivery terms should also be taken into consideration
• Zhejiang Huayi, for instance, is known for its high-purity lithopone products, while Zibo Dongfang Jincheng offers customized solutions to cater to diverse customer needs. Shanghai Kangle, on the other hand, boasts an extensive distribution network, ensuring timely delivery and efficient service.

• Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.

• Titanium dioxide is primarily used as a pigment in paints, plastics, paper, and other materials. Its ability to reflect light makes it an ideal choice for enhancing color and opacity. Moreover, titanium dioxide's stability and non-toxic nature ensure that it remains safe and effective over time.
• Moreover, these manufacturers often provide technical support and guidance to ensure their products meet the precise needs of their customers. They offer comprehensive data sheets and application guides to help users maximize the benefits of lithopone in their formulations.

• A steep decline in the prices of titanium dioxide was observed in the second half of 2022 as the erratic energy costs along with rising covid cases affected the market negatively. In addition to this, the decreased offtakes from paints and coating industries, weak economic growth, and strict restrictions imposed to deal with the resurgence of covid cases further aided the declining trajectory of titanium butoxide prices.

• Polyvinyl Butyral Resin (PVB) is a solvent Resin synthesized by the acetal reaction of Polyvinyl Alcohol (PVA) and butyraldehyde in contact with coal.
  
  Because Pvb Resin itself contains a lot of hydroxyl groups, it can bridge with some thermosetting resins to improve the properties of chemicals and film hardness.
  
  Because PVB resin has the above excellent characteristics, it is widely used in adhesive safety glass intermediate film of automobile and building, rust cutting primer, baking paint, wood paint, printing ink, adhesive of electronic ceramics and printed circuit board, adhesive between metal and metal, between metal and plastic, modifier of hot-melt adhesive, iron dimension waterproof processing of textile, etc. A variety of new industrial applications are also continuously developed and applied.
  
  The general characteristics of PVB are as follows:
  
  The appearance of polyvinyl butyral (PVB) resin is white spherical porous particles or powder, and its specific gravity is 1:1; However, the filling density is only 0.20 ~ 0.35g/ml.
  
  Thermal properties
  
  The glass transfer temperature (TG) of polyvinyl butyral (PVB) resin ranges from 50 ℃ of low degree of recombination to 90 ℃ of high degree of recombination; The glass transfer temperature can also be adjusted by adding an appropriate amount of Plasticizer to reduce it below 10 ℃.
  
  Mechanical properties
  
  The coating of polyvinyl butyral (PVB) resin has good water resistance, water resistance and oil resistance (it is resistant to aliphatic, mineral, animal and vegetable oils, but not to sesame oil). PVB is widely used in printing inks and coatings because it contains high hydroxyl groups and has good dispersibility to pigments.
  
  In addition, its chemical structure contains both hydrophobic acetal and acetic ACID groups and hydrophilic hydroxyl groups, so PVB has good adhesion to glass, metal, plastic, leather and wood.
  
  Chemical reaction
  
  Any chemical that can react with secondary alcohol will also react with PVB. Therefore, in many applications of PVB, it is often used with thermosetting resin to bridge and harden with the hydroxyl group of PVB, so as to achieve the characteristics of chemical resistance, solvent resistance and water resistance.
  
  Of course, films with different characteristics (such as hardness, toughness, impact resistance, etc.) can be prepared according to different types of thermosetting resin and different mixing ratio with PVB.
