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.

Inventory: Low inventory of mainstream producers, it is expected that the overall size of spot inventory today is low, and there is less stock in mainstream factories.2. Mentality: the buyer has to prepare goods in advance, and the new order price is slightly less willing to purchase in bulk; Because the seller's inventory is small, the manufacturer has no willingness to reduce the price of sales, and the demand for new orders in the market is relatively large.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyers still have inventory digestion, and the intention to supplement orders in the short term is limited. It is expected that the market price of titanium dioxide is stable today, and the market trading atmosphere is more general.
According to the feedback of manufacturers, the new orders of mainstream factories maintain stable prices, and the overall new volume of the market is limited. On the demand side, the terminal basically had batch replenishment last month, and the purchase intention of new orders was low; On the supply side, mainstream manufacturers normally produce and deliver goods, and the actual output of the industry is stable. Most factories quote a new price of 17,000 yuan/ton or more market negotiation range reference 16000-17200 yuan/ton, plastics and papermaking related downstream feedback part of the tight model price is higher. Recent titanium dioxide raw materials are expected to weaken, titanium dioxide price support is relatively limited, comprehensive market factors, the current titanium dioxide market many buyers hold a wait-and-see mentality.

  • Hydroxypropyl methyl cellulose meeting the food additive specification is consequently considered safe for all animal species. Setting a maximum content in complete diets is not considered necessary. The low toxicity of celluloses shown in the toxicological studies (see Section 3.2.2) support this conclusion.

  • Tile adhesive is a vital component in the installation of tiles, as it provides a strong and durable bond between the tile and the substrate. HPMC enhances the performance of tile adhesive by improving workability, water retention, adhesion, and overall durability.
  • Lange Zeit war das einzige Material für die Herstellung von Kapselhüllen Gelatine. Gelatine wird aus der Haut und den Knochen verschiedener Tierarten, insbesondere Schweinen und Rindern, gewonnen. Aufgrund strenger Vorschriften für die Verwendung von Gelatine durch auftretende Krankheiten wie TSE (Transmissible Spongiforme Enzephalopathie), wozu u. a. BSE (Bovine Spongiforme Enzephalopathie) zählt, wurde die Suche nach einem Ersatz für Gelatine gefördert.

    Seit 1998 gibt es auch pflanzliche Kapseln auf dem Markt. Mit HPMC steht den Verbrauchern ein völlig unbedenkliches, pflanzliches Produkt zur Verfügung, sodass auch Veganer oder Vegetarier und Menschen, die aufgrund ihrer Religion auf Gelatine verzichten,eine Alternative zu Gelatine-Kapseln haben.

    HPMC-Kapseln halten hohen Temperaturen sowie hoher Luftfeuchtigkeit stand und besitzen einen geringen Eigenfeuchtigkeitsgehalt. Dadurch sind die Kapselhüllen zur Aufbewahrung von feuchtigkeitsempfindlichen Zutaten geeignet. Sie schützen somit ihren Inhalt vor allen Arten von Schwankungen wie beispielsweise Temperaturschwankungen und Feuchtigkeit. HPMC-Kapseln sind somit
  • The benefits of using redispersible polymer powder are manifold. Foremost among these is its exceptional adhesion strength. The polymers in the powder form a strong bond with various substrates, including concrete, masonry, and tiles, ensuring durable and long-lasting installations. Additionally, the elasticity of the polymers allows for some degree of movement in the applied material without cracking or breaking, providing excellent flexibility and resistance to temperature changes and structural shifts.

  • In the pharmaceutical sector, HPMC plays a crucial role as an excipient. It is used as a binder in tablet manufacturing, enhancing the tablet's integrity and strength. Additionally, it serves as a viscosity enhancer in liquid formulations, improving the suspension stability. HPMC is also used as a controlled-release agent, allowing for sustained drug delivery, thereby increasing medication effectiveness and reducing side effects.
  • The term HPMC is an abbreviation that combines the key components of the compound. Hydroxypropyl refers to the presence of hydroxypropyl groups, which are derived from propylene oxide. Methylcellulose, on the other hand, signifies the methyl groups attached to the cellulose backbone, resulting from a reaction with methanol. The combination of these two modifications imparts distinct characteristics to HPMC that make it suitable for different uses.
