Yesterday, some parts of the domestic rutile, anatase titanium dioxide new single price to maintain stability, titanium dioxide factory normal, more delivery of early orders, spot shipping pressure is small; And the buyer just needed to buy a few days ago. Downstream manufacturers are currently watching the latest execution price.The key factors affecting the current market price change1. Inventory: Low inventory of mainstream producers, mainly delivery of pre-contract orders, is expected today's spot inventory is still low, mainstream factories before the holiday spot tension.2. Mentality: the buyer has to prepare goods in advance, and the new order price is slightly less willing to purchase in bulk; Sellers due to the lack of inventory, manufacturers have no willingness to reduce the price of sales in the market of new orders just need to buy more.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyer's early orders continue to digest, and the acceptance of the purchase before the holiday is acceptable. It is expected that the market of titanium dioxide just needs to be closed today, and it is concerned about the new execution price of the mainstream factory.
This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
Below are selected applications of photocatalytic pollutant decomposition processes on titanium oxide:
1. Self-cleaning surfaces: for the production of glass for spotlights, traffic lights, car mirrors, window panes, for road paints, for covering sound-absorbing screens and tunnel walls.
2. Air cleaning and odor removal: filters that are used in enclosed spaces (e.g. public toilets) or filters for air-conditioning equipment.
3. Water treatment: groundwater treatment installations, water purification installations in the intakes of drinking water from rivers.
4. Self-disinfecting materials: towels, linings, clothing, equipment in hospitals, wall surfaces of operating rooms.
5. Removal of lesions: anti-cancer therapy.
