Dense Fused Alumina Fine Powder
Dense fused alumina fine powder is the product passing the finest screen in the segment sand production line. The available size is 100#-0, 200#-0, 320#-0 and 0-1mm. It can be used as a high-quality powder for shaped refractory and unshaped refractory. At the same time, the fine powder can also be directly used as refractory powder and filler.
Dense Fused Alumina Fine Powder（FAQ）
What are the different types of abrasive bonds used in coated abrasives?
Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials. Phenolic Resin – This system uses full phenolic resin for both coats. It is designed to withstand moisture
What is the refractive index of white fused alumina compared with that of glass?
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
Will the same product from two different manufacturers perform the same if they are marked the same?
This is a hard question to answer in a short space. While the markings mean the wheels should perform the same, differences in factory equipment and marking systems may make one product behave differently than another. They should be close, but the only true way to match a product is
How is fused alumina obtained?
Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance, bauxite is used for the manufacture of brown and semi-friable fused alumina,
Can you produce according to the samples?
Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.
