1. The difference between dry sanding and wet sanding
Sandpaper is a common abrasive material, widely used in the grinding and polishing of various materials such as metal, wood, plastic, etc. Dry sanding and wet sanding are two common types of sandpaper, and there are several differences between them:
1. Wet sanding needs to be soaked in water before use, while dry sanding is used directly.
2. Wet sanding produces mud when used and needs to be cleaned in time, while dry sanding does not produce mud.
3. The grinding force of wet sanding is weaker than that of dry sanding, so it is not suitable for grinding operations that require a larger scale.
4. Wet sanding is suitable for work in water, such as walls and floors; while dry sanding is suitable for dry grinding operations, such as grinding and polishing of metal, wood, plastic, etc.
2. Tips for using dry wet sanding
1. Choose the sand grains correctly and choose the appropriate sand grain size according to your needs.
2. Maintain a good feel, control the force, and avoid excessive resistance of sandpaper and burn the surface of the material.
3. When using water-abrasive sandpaper, you need to keep it wet to keep the surface of the sandpaper moist.
4. When using dry sandpaper, do not use old sandpaper to avoid affecting the effect.
5. When using sandpaper, you should first use coarser sand for grinding and gradually transition to finer sand.
In general, the skills of using dry or water-abrasive sandpaper are the same. It is very important to choose the right sand, maintain a good feel, and control the strength.
[Conclusion] Dry and water-abrasive sandpaper are common grinding tools. The difference between the two lies in the way of use, grinding strength, etc. When using sandpaper, you need to pay attention to the skills, choose the right sand size, maintain a good feel and control the strength, etc., to achieve a good grinding effect.
