Preparation and performance study of white corundum waterborne polyurethane coating In order to solve the problem that the waterborne polyurethane coating used in the market is expensive and has low wear resistance, and cannot meet the needs of sports shoes for high quality, low cost, wear resistance and scratch resistance, this study provides a white
What does the D50 of white corundum micro powder mean? Generally speaking, the D50 value of white corundum powder is the size of 100 white corundum particles of different sizes or arranged from large to small, and the size of the 50th particle D represents the diameter of the powder particles, D50 represents the diameter
The significance of white corundum micro powder particle size and mesh number The significance of white corundum micro powder particle size and mesh number The particle size and mesh number of white corundum are the most important indicators of white corundum, so what are the particle size and mesh number of white corundum powder? 1.Explanation
What is the difference between white fused alumina and alumina? It’s just that many people are not technical, but laymen. They don’t know much. They vaguely know that the alumina content of white fused alumina is more than 99%, close to 100%. Then they can’t understand the relationship between them. They even think they are
How to detect the particle size of white corundum? Let’s learn about the detection method (1) Advantages of screening method: simple, intuitive, low equipment cost, commonly used for samples larger than 40um. (2) Microscope (Image) Method – Advantages: Simple and intuitive, capable of morphology analysis, suitable for samples with narrow distribution. Disadvantages: Poor representativeness, difficult
Pickling and moisture process of white corundum powder There are two methods for separating white corundum, moisture and wind selection Moisture is to control the water pressure to gather the powder of different particle sizes together. The white corundum powder produced by this production method has no large particles and concentrated particle size Wind-selected white
