Introduction to the use of water sandpaper and product characteristics in the process of decoration
Water-resistant sandpaper is mainly named because it can be ground by immersion or water during use. Water-resistant sandpaper is based on water-resistant latex paper or waterproof-treated kraft paper, and uses various resins as binders. Aluminum oxide abrasives or abrasives such as silicon carbide are firmly adhered to the substrate. A coated abrasive tool made of abrasives, which can be processed into A4 paper-sized pages and various customized sizes.

Use of water sandpaper:
1. Sandpaper also plays a great role in the production of models, such as eliminating the water nozzles of parts, grinding the gaps of parts cut from the runner, etc. Sometimes you can also use fine-grained sandpaper to remove the luster of spray paint and remove the oxide layer of metal parts. It is the metal parts that emit their original metallic luster. Oil and grinding on water sandpaper can make the wooden model show a soft luster.
2. Sandpaper is called an industrial beautician. At this time, let's take a look at the things around us. Every item such as computers, mobile phones, tables, teacups, leather shoes, etc. is inseparable from the shadow of sandpaper abrasives. It is precisely because human beings are good at creating tools and using tools that we have a colorful world. Wood, leather, plastic, metal and other raw materials cannot become commodities themselves, nor can they be used directly, but can be cut, processed, combined, deformed, ground and other processes. In these links, polishing and grinding is the most critical step to realize the perfection of commodities. Therefore, the manufacturer must carefully choose the appropriate sandpaper belt to achieve the flawless surface of the product.

3. If it is to grind a relatively rough surface, such as metal grinding, mahogany furniture grinding, paint grinding, wall grinding, etc. Due to the rough structure of the surface of such objects and the large grinding particles, it is suitable to choose overlay dry sandpaper. Because the sand grains of dry sandpaper are coarser and harder than water sandpaper, the gravel particles are matched with the surface particles of the object, and the grinding efficiency is higher, which can grind a relatively smooth spherical effect in the fastest time. If you grind PVC circuit boards, mobile phone casings, jade, precision instruments, etc., due to the small grinding particles on the surface of the object, the fineness is required to be higher, especially for precision machining and manual grinding, it is suitable to choose water sandpaper with a relatively thin paper base and fine grit. Water sandpaper can be ground by water, while dry sandpaper cannot be ground by water because of overlaying grit and glue. At present, there are three kinds of water sandpaper that are more popular in Suzhou Shangyan Abrasives, CP34, CP35, CP38. It is imported from Riken Research Institute in Japan, and the grinding effect is very excellent.

Water sandpaper features:
1. There is no dust hazard when grinding with water, and no dust explosion will occur;
2. The polishing quality is higher than that of ordinary dry-ground sandpaper. When grinding with water, the surface of the sandpaper should not be blocked, and the sandpaper has a long life.
3. The particle size distribution of water-resistant sandpaper is wide from P60 to P5000. For products, the finest dry-ground sandpaper is generally around P1000. Water sandpaper is especially suitable for high-precision polishing of fine grains.
4. Fine-sized water-resistant sandpaper is more cost-effective than other precision grinding materials, and the price is relatively cheap. It can be used for water mill and dry grinding, and has a wide range of adaptability.
