For a mini-review published in the journal Particle and Fibre Technology in 2021, scientists wanted to evaluate whether Ti02 particles contributed to the development and/or exacerbation of irritable bowel disease, and whether they altered the four elements of intestinal barrier function: the intestinal microbiota, the immune system, the mucus layer, and the epithelium. The breakdown of these four elements can contribute to autoimmune, neurological, inflammatory, infectious, and metabolic diseases. Following their review, the researchers concluded: “Data indicate that TiO2 is able to alter the four compartments of IBF and to induce a low-grade intestinal inflammation associated or not with pre-neoplastic lesions.”
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.
At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.
Lithopone B301, Lithopone B311 powder is also called C.I. 77115; Pigment White 5; Barium zinc sulfate sulfide and belongs to Product Categories of Inorganic & organic chemicals; uvcbs-inorganic. Lithopone B301, Lithopone B311 powder is used in water-based paints because of its excellent alkali resistance. It is widely utilized as a whitener and reinforcing agent for rubber and as a filler and whitener for paper. Lithopone B301, Lithopone B311 powder is considered to be poisonous because it is able to liberate hydrogen sulfide upon decomposition by heat, moisture, and acids. When heated to decomposition Lithopone B301, Lithopone B311 powder emits highly toxic fumes of SOx, ZnO, and H2S.
