The Difference Between Abrasive Velcro Sanding Discs And Flap Discs
Abrasive Velcro disc sand and flap discs are common grinding products, and they have certain differences in usage, materials, appearance, etc. This article will give you a detailed introduction to the differences between abrasive disc sand and flap discs.
1. Differences in usage methods: Abrasive sanding discs usually use abrasive materials in combination with abrasive discs and grind them by rotating. Abrasive materials can be aluminum oxide, zirconium corundum, ceramics, etc. Different abrasives can be selected according to actual needs. The flap disc is made of abrasive materials into sheets and is operated in the form of sheets during grinding. When in use, the flap disc needs to be fixed on the grinding tool, and then the grinding operation is performed.
2. The difference in materials: Abrasive disc sand is a kind of round sandpaper, and its back is covered with a layer of flannel. The characteristics of flocked disc sand are its good elasticity, high efficiency, good heat dissipation, and low noise. It can be processed into a round or square shape and used with a special sanding machine. It has strong adhesion, is not easy to fly, has strong anti-clogging properties, can be used wet and dry, and is more wear-resistant than traditional sandpaper.
Flap discs are fan-shaped grinding tools composed of multiple thin blades. The characteristics of the flap disc are its good elasticity, high efficiency, good heat dissipation, and low noise. It can be used to grind welds, edge burrs, etc.
3. The difference in grinding effect: The Abrasive sandpaper disc can grind the workpiece more evenly through the rotation of the velcro disc, making it less prone to scratches and unevenness. On the other hand, with the flap disc, only flaky abrasives contact the workpiece during grinding. The grinding effect is relatively uneven, and scratches and unevenness are prone to occur.
4. Differences in the scope of application: Hook and Loop disc sand is suitable for grinding workpieces with larger areas, such as automotive painting and refinishing, Better surface quality on paints sanding and polishing, Flatting of filler and putty, lacquer to painting, etc. Its plush discs can effectively protect the workpiece surface and reduce scratches and damage. The flap discs are suitable for workpieces with smaller areas and specific shapes, such as metal parts, ceramics, etc.
To sum up, there are certain differences between Velcro disc sand and flap discs in terms of usage methods, materials, grinding effects, and scope of application. According to actual needs, appropriate grinding products can be selected to process the workpiece. For large-area grinding work, abrasive disc sand is more suitable; for small-area and specific-shaped workpieces, you can choose louver blades for grinding. No matter which product you choose, you need to use it reasonably according to the actual situation to achieve better-grinding results.
