Binders, Abrasive Distribution and Causes of Failure of Coated Abrasives
This article discusses the factors influencing the performance of coated abrasives, including the properties of binders, abrasive distribution states, and causes of failure. It details the adhesive types used in coated abrasives, such as phenolic resin and animal glue, and their applications. Key abrasive characteristics like shape, hardness, toughness, and self-sharpening are also analyzed, with comparisons between materials like silicon carbide, aluminum oxide, and zirconia corundum. The article explains failure modes of abrasives, such as dullness, clogging, and shedding, and provides recommendations for selecting abrasives based on different workpiece materials. Standards like FEPA and JIS are also mentioned for particle size classification.

What is the Bonding Mechanism and Bonding Agent Formula of Coated Abrasives?
In the research and understanding of the bonding mechanism of adhesives to abrasives and substrates in the manufacture of coated abrasives, many theoretical viewpoints have been proposed, but no consensus has been reached. The main bonding mechanisms are physical adsorption theory, mechanical bonding theory, diffusion theory, electrostatic theory, and chemical bond theory. Physical adsorption theory is often used to explain why abrasives are bonded to the substrate. According to the material structure theory, there are main valence forces of chemical bonds and weaker van der Waals forces (including bond forces, dipole forces, induced dipole forces, and dispersion forces) between atoms and molecules in the aggregated state of the material. The solid surface adsorbs liquids and gases due to the van der Waals force. This effect is called physical adsorption. Due to the physical adsorption effect, the adhesive completely infiltrates the surface of the adherend before curing, and the molecules are close enough to each other, so the van der Waals force between the molecules has a high adhesion strength.

From Coarse to Ultra-Fine: Understanding Sandpaper Grits for Perfect Finishes
Paper-based abrasives are relatively cheap and require no or only simple substrate treatment. Coated abrasives with paper-based backing are relatively flat and have unique adhesion, elasticity, weight, moisture absorption and waterproof capabilities. Paper-based coated abrasives are light, easy to cut, and inexpensive. They are suitable for applications with low pressure and need to be attached to the surface of the workpiece when applied. Paper-based sandpaper is widely used in the processing of various materials such as metal, wood, plastic, and coated surfaces.

Applications of Brown Fused Alumina in Abrasives and Refractory
Brown Fused Alumina, also known as fused brown corundum, or emery, is a brown artificial corundum made of high-quality bauxite, carbon materials, and Iron chips that are reduced by electric melting in an electric arc furnace, so it is named Brown Fused Alumina ( also called brown corundum ). The main chemical composition of brown fused alumina is Al2O3, and it also contains a small amount of Fe, Si, Ti, and so on. Brown Fused Alumina is more widely used in abrasives and refractory materials, because of its good performance, wide range of applications, and cheap price.
