Basic knowledge of sandpaper:
In practice, the classification of sandpaper is not uniform.
Sponge, sand paper
Suitable for polishing smooth parts with various materials.
Sponge sandpaper sanding process has the characteristics of high production efficiency, good surface quality and low production cost, so it is widely used in furniture production. The final surface quality of furniture products is closely related to sanding process. Sponge sandpaper is the main tool in sanding process.
Dry abrasive paper
Dry abrasive paper synthetic resin as the binder to silicon carbide abrasive adhesive on latex, made of high-grade products and coated with antistatic coating has good anti clogging, antistatic, soft, high wear resistance, etc. Selection of a variety of fineness, suitable for grinding the metal surface, putty and coating. Dry abrasive paper generally choose special kraft paper, and latex paper, selection of natural and synthetic resin as binder, through advanced high electrostatic sand craft manufacture, high grinding efficiency, the product is not easy to stick dust etc, suitable for dry grinding. Widely used in furniture, decoration and other industries, especially the coarse grinding.
Waterproof abrasive paper
Texture is more fine, water abrasive sandpaper is suitable for grinding some of the finer texture of things, and suitable for processing;
Waterproof abrasive paper gaps between the sand it is small, the grinding of pulverized also smaller, with water when using pulverized can follow the water out, so should be used with water, if take water sand paper dry grinding crushed will stay in clearance of sand, make the sand paper surface light to reach the effect of it, and dry sand paper is not so trouble, large gaps between the grains of sand grinding out pulverized also larger it due to the large gap in the process of grinding crushed will fall down, so it don't need to use together with water.
By product name:
Wood sandpaper, namely dry sandpaper; Waterproof abrasive paper, namely, water-resistant sandpaper; Iron cloth, it is a kind of dry abrasive paper, coarser, can be polished metal surface as soon as possible.
Water sand paper or as a water-resistant sandpaper waterproof abrasive paper, because when use can be immersed grinding or polishing the name in the water, water proof abrasive paper is waterproof paper or treated and water resistant paper as the substrate, paint, or resin as binder, the corundum and silicon carbide abrasive firmly stick to the substrate and made a grinding tool, the shape of pp and volume two.
Its characteristics are:
1. The linkage line production, high efficiency;
2. The adoption of varnish binder, water-resistant sandpaper so the drying time is longer, the drying methods of general hanging drying;
3. The grain size of water-resistant sandpaper is generally fine. The grain size of water-resistant sandpaper in China starts from P80, and the fine grain connects with the grain size of metallographic sandpaper.
4. Water-resistant sandpaper is generally in water-bearing conditions for grinding operations, so less dust, good working conditions.
Divide by abrasive
Brown corundum sandpaper; White corundum sandpaper; Silicon carbide sandpaper; Zirconium corundum sandpaper, etc.
According to the bonding agent points:
Ordinary binder sandpaper; Resin adhesive sandpaper.
Still have coarse sandpaper and fine sandpaper cent.
