There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.
The evidence also suggests that the toxicity of TiO2 particles may be reduced when eaten as part of the diet. This is because proteins and other molecules in a person's diet can bind to the TiO2 particles. This binding alters the physical and chemical properties of the particles, which influences how they interact with cells, tissues and organs.
2. Load Capacity When selecting steel grating, it is crucial to evaluate its load capacity. This is typically specified in pounds per square foot (psf) or kilograms per square meter (kg/m²). The load rating depends on the spacing of the bars and the thickness of the material. Common load classifications include light-duty, standard-duty, and heavy-duty, each designed for different weight-bearing requirements.
A gate valve is a type of valve that opens or closes by lifting a gate out of the path of the fluid. Unlike other valves, such as globe or ball valves, gate valves are primarily designed for unidirectional flow and are best suited for applications where a straight-line flow of fluid is required. They are known for their ability to provide minimal resistance to flow when fully open. Gate valves can be constructed from a variety of materials, including cast iron, stainless steel, and brass, depending on the specific needs of the application.
