First, the role of abrasive paper
Abrasive paper is a tool used for grinding and grinding, which can cut and remove the poor quality of the workpiece surface. In the fields of home improvement, home DIY, vehicle maintenance and handicrafts, sandpaper is one of the basic necessary tools. Its main role includes the following aspects:
1. Remove dirt: abrasive paper can remove dirt and stains on the surface of the material, making the item more beautiful and tidy;
2. Polishing treatment: sandpaper can make the surface of the material become more smooth and smooth, to achieve the effect of polishing treatment, make the material more beautiful;
3. Dressing position: sandpaper can help workers trim the surface of items during maintenance or production, making it smoother and more beautiful;
4. Remove burrs: abrasive paper can remove burrs and rough parts on the surface of the material to achieve a smooth effect and make the product smoother and neater.
Second, the classification of abrasive paper
According to different grit and use, abrasive paper can be divided into a variety of types, common types are:
1. Water abrasive paper: suitable for water abrasive work, can reduce the production of abrasive chips in the grinding process, extend the service life of sandpaper;
2. Dry abrasive paper: suitable for dry grinding work, can quickly remove dirt and stains on the surface of the material;
3. Emery abrasive paper: suitable for metal, building materials and other hard materials grinding work, with strong anti-wear performance and service life;
4. Alumina abrasive paper: suitable for wood, synthetic materials and other materials grinding work, with high flatness, strong grinding force and other characteristics.
Three, the use of sandpaper skills
Abrasive paper in the process of use need to pay attention to the following tips:
1. Choose the right sandpaper: Choose the right sandpaper according to the desired grinding effect and material hardness;
2. Pay attention to the grinding direction: the grinding direction of the sandpaper should be consistent with the texture direction of the material, otherwise the surface of the material will become uneven;
3. The conversion between different abrasive particle size should be sequential step by step, and the wear marks generated by the last grinding should also be ground away to avoid affecting the subsequent grinding effect;
4. Water grinding agent: In the grinding process, adding water or other grinding agents helps to reduce the wear of the sandpaper and the heat of the material surface.
In short, abrasive sandpaper is an essential tool that can play a great role in the manufacturing, repair and home improvement process. In order to ensure its effective use, it is necessary to pay attention to the selection of the appropriate sandpaper and the correct use of skills, and to carry out appropriate maintenance and replacement during use.
