How to choose the right sandpaper

Choosing the right sandpaper is crucial to completing the task. The following points are the key to choosing the right sandpaper:
1. Granularity: The particle size of sandpaper is usually identified by "number", such as 40, 80, 150 and so on. The smaller the particle value, the coarser the particle, which is suitable for grinding rough surfaces; The larger the particle value, the finer the particle, suitable for smooth surface grinding and finishing.
2. Types of sandpaper: There are dry sandpaper and wet sandpaper. Dry sandpaper is suitable for routine sanding and finishing work, while wet sandpaper is especially used in situations where work needs to be done in water, such as fine sanding of glass, ceramics and metals.
3.Material: The material of sandpaper includes paper and adhesive. High-quality sandpaper uses durable paper materials and uses high-quality adhesives to bond abrasive particles. High quality sandpaper can provide better performance and service life.
4. Manufacturer: Choosing sandpaper produced by well-known manufacturers can ensure the reliability of quality. Good manufacturers usually offer products with a variety of specifications and ensure consistent quality.
