Q titanium dioxide concrete mix

EricCissie Release Time: 3月 21, 2024, 10:22 下午

Titanium Dioxide Concrete Mix is a type of concrete mix that includes a certain amount of titanium dioxide. The main purpose of adding titanium dioxide to the concrete mix is to enable the concrete to be more resistant to pollutants. When sunlight hits the titanium dioxide in the concrete, it stimulates a chemical reaction that breaks down many types of pollutants, essentially cleaning the air. This photocatalytic reaction can help to keep city air cleaner and offset the pollution produced by cars and industry. This technology is being tested and used in various parts of the world. For example, highways in the Netherlands use this type of concrete to help break down nitrogen oxide gases from car emissions. To make titanium dioxide concrete mix, a certain percentage of titanium dioxide is added along with the aggregate, cement, and water used to create standard concrete. The exact percentage of titanium dioxide included can vary based on the desired level of pollution resistance and t...

Q titanium dioxide extraction process

BrookDavy Release Time: 3月 21, 2024, 10:11 下午

Titanium dioxide is primarily extracted from the ores rutile, ilmenite, and leucoxene, using either the sulfate process or the chloride process. 1. Mining and Concentrating: Titanium ores are first mined and then concentrated into heavy mineral sands. These sands are then transported to a separate facility for further processing. Sulfate Process: 2. Conversion to Titanium(IV) Chloride: The concentrated ores are mixed with sulfuric acid (H2SO4) and water and then heated, which converts them into a titanium sulfate solution. 3. Hydrolysis: This solution is cooled and then diluted with water. Hydrolysis then takes place, causing the formation of Hydrated Titanium Dioxide. 4. Calcination: This product is then heated in a calcination process which removes all water molecules and leaving behind pure Titanium Dioxide. Chloride Process: 2. Chlorination: In the chloride process, the concentrated ores are mixed with chlorine and carbon, at high temperatures. The chlorine reacts with the ti...

Q is titanium dioxide and zinc oxide safe for pregnancy

BrookDavy Release Time: 3月 18, 2024, 8:40 下午

Yes, both titanium dioxide and zinc oxide are considered safe for use during pregnancy. They are physical sunscreens that sit on the skin’s surface and act as a barrier to reflect harmful UVA and UVB rays. They do not penetrate the skin or enter the bloodstream, reducing any risk for the mother or developing fetus. However, always consult a healthcare professional before introducing any new products to your skincare routine during pregnancy.
