Sandpaper is widely used in mobile phones, cars, and wood products and so on. Secondly, it also plays an important role in the coating construction process .There are different types of sandpaper and generally divided into:
- sponge sandpaper
- dry sandpaper
- water sandpaper
What they all have in common is the use of adhesives to bond different abrasive and substrates together.
Sponge Sandpaper
It is the main tool of the sanding process, suitable for sanding the oily part, all kinds of materials can be used. The sponge 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 the sanding process.
Dry Sanding Paper
It uses synthetic resin as a binder to bond silicon carbide abrasives on latex, and is coated with an antistatic coating to make a high-grade product. It has the advantages of anti-blocking, anti-static, good softness and advanced wear resistance. Available in a variety of fines, suitable for sanding metal surfaces, wood surfaces, putties and coatings. Dry sanding paper is generally made of special kraft paper and latex paper, and natural and synthetic resins are used as binders. It is made by advanced high-static sand-planting process. This product has high grinding power and is not easy to stick. Dry sandpaper has a large gap between the sand particles, and the grinding debris is also large. During the use process, the debris will fall by itself because of the large gap, so it does not need to be used together with water. The grain is generally high-quality silicon carbide, and the paper base is generally made of latex paper, so it has better flexibility, better heat dissipation during use, and is not prone to blockage. Dry sandpaper or sanding disc is widely used in wood processing, stone processing, precision mold grinding, synthetic material processing and other industries and types of work, and is widely used in furniture, decoration and other industries.
Water Sandpaper
It is also called waterproof sandpaper. The grit material of that is generally silicon carbide, and the paper base is usually kraft paper. There are also relatively high-end ones and many of the paper bases are latex paper. The characteristics of latex paper are good flexibility and stronger surface adhesion of sand particles, so the sand paper is more durable, the particles are more uniform, and the polishing effect is more excellent. The gap between the sand grains of the water sandpaper is smaller than that of the dry one and the debris of the ground items is also smaller. When used with water, the debris will flow out with the water, and then maintain the sharpness of the surface of the sandpaper. If the water sandpaper is used for dry grinding, the product debris will adhere to the gaps of the sand grains, so that the surface loses its sharpness and has no grinding force. Then it fails to work. That is widely used in stone grinding, hardware processing, mold processing, wall putty grinding, car surface grinding, rust removal, paint removal and other industries.
Conclusion
The above is the specific introduction ofsponge sandpaper, dry sandpaper and wet sandpaper. You can choose suitable products according to different usage scenarios. It is better to use dry sanding paper for wood works. However, if you need to sand finer car surfaces, it is better to choose water sandpaper for metal. BINIC ABRESIVE INDUSTRY Co., Ltd.: Coated abrasives manufacturers, your best choice.
