countersunk self drilling screws

A hex head self-drilling screw is a type of screw that incorporates a hexagonal head, allowing it to be driven with a wrench or socket, offering greater torque and stability during installation. The self-drilling feature means that the screw has a unique point design that allows it to drill its own pilot hole in materials like metal, wood, and plastic without the need for pre-drilling. This eliminates the need for additional tools and saves time, making it an efficient choice for various applications.

  • Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

  • Price trend

    The successful completion of 2022. Looking at the development of     Titanium Dioxide market in this year, from the perspective of price, according to the monitoring of bulk commodity data, the price of titanium dioxide will fall in 2022. The average price of domestic titanium dioxide at the beginning of the year was 20733.33 yuan/ton, and the average price at the end of the year was 15933.33 yuan/ton. The price fell by 23.15% during the year.

    2. Market analysis

    Product quotation

    From the perspective of market development in 2022, prices in the first half of the year are basically in a stable stage, with little fluctuation, and prices in the second half of the year are in a rapid decline stage. In November, Longqi sent a letter to raise the price to stabilize the price. At this time, the price of titanium dioxide began to stabilize and stop falling.

    In the first quarter, export orders performed well, and the market confidence of titanium dioxide enterprises was good. Before the year, domestic downstream manufacturers mainly hoarded goods moderately before the year. The market rose twice, with a cumulative increase of 1.77% from January to March. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly 20000-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 18000-19500 yuan/ton. After the year, the domestic raw material sulfuric ACID price continued to rise, the enterprise cost was under pressure, and the support was strong. The titanium dioxide market confidence was fair, and the price continued to rise.

    In the second quarter, the logistics management and control and the domestic market turnover were light. Affected by logistics control and other factors, transportation is relatively difficult, market supply is shrinking, traders are unstable, and the market price declines with the focus on digesting their own inventory. The cumulative decline from April to June was 3.08%. The ex factory quotation of domestic rutile titanium dioxide including tax is between 19100-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 17800-19000 yuan/ton. The spot market of titanium ore continued to decline, the price of sulfuric acid also continued to decline, and the cost support was weak. At the same time, the performance of the downstream terminal real estate market is poor. Under the superposition of multiple negative factors, the titanium dioxide market fell.

    In the third quarter, Longqi guided the price reduction and the titanium dioxide market fell sharply. 7-9 The cumulative decline was 19.85%. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly between 15500-17000 yuan/ton; The quotation of anatase titanium dioxide is between 14500-15500 yuan/ton. Due to the limited power supply and other factors, the titanium dioxide enterprises in southwest China have reduced their production. The market price of raw sulfuric acid fell rapidly, and the cost support was weak. In addition, the domestic titanium dioxide market demand continues to be sluggish, and the manufacturer's inventory pressure is still large.

    In the fourth quarter, Dragon Enterprise sent a letter in November to promote stability. The cumulative decline was 2.55% from October 12. The titanium dioxide market is about to enter the off-season, and the demand market for coatings is tepid, especially in the northern market. In November, the group announced that the price would rise, and the prices offered by various manufacturers were flexible, so it was more meaningful to stop the decline. Most domestic rutile titanium dioxide prices are between 15000-17500 yuan/ton; The quotation of anatase titanium dioxide is about 14000-14500 yuan/ton. The price of titanium concentrate in Panxi increased. More than 20 domestic titanium dioxide enterprises sent letters to announce the increase, and the international giants Chemurs and Tronox announced the reduction of titanium dioxide production in the fourth quarter, which also benefited the domestic titanium dioxide market and stabilized the market on the whole.

  • On the other hand, the sulfate process involves treating ilmenite ore with sulfuric acid to produce titanyl sulfate solution, which is then calcined to produce titanium dioxide. This method produces lower-quality titanium dioxide with a higher impurity level, making it less expensive than the chloride process. However, the sulfate process is more commonly used due to its lower cost and higher yield.
  • Superfine calcium carbonate is also widely used in the plastics industry for its ability to improve the mechanical properties and processing characteristics of plastic products. It can be added to plastic formulations to increase stiffness, impact resistance, and heat resistance, making it a popular choice for manufacturers looking to enhance the performance of their products.
  • Furthermore, the competitive landscape in China's lithopone pigment industry should not be overlooked. Major players like Zhejiang Huayi Chemical, Yunnan Yuntianhua, and Sichuan Long March Chemical compete fiercely, often adjusting their prices to maintain market share.

  • Titanium dioxide prices (anatase grade) increased steadily across the United States, rising 2.27% from January 2021 to March 2021, and were settled at 3150 USD /MT by the conclusion of the quarter.
