The Use of Water Sandpaper

During the decoration process, the use and product features of water sandpaper are introduced. Water sandpaper is mainly used for wet sanding or water sanding. The name "waterproof sandpaper" is because it is made by firmly attaching aluminum oxide abrasive or silicon carbide abrasive to the base material, which is made of waterproof latex paper or waterproof treated calfskin paper as the base material and various resins as the binder. It can be processed into various shapes, such as A4 paper size sheets, and various customized sizes.

Application of water sandpaper

Abrasive paper is known as an industrial beautician. Let us take a look at the things around us, such as computers, mobile phones, tea cups, leather shoes, etc. Every item cannot be separated from the polishing of sandpaper abrasives. Wood, leather, plastic, and metal cannot be used as products directly. They need to be cut, processed, assembled, painted, and polished in order to be used. Among these processes, polishing and sanding are the most critical steps to achieve a perfect product appearance. Therefore, manufacturers must carefully select suitable abrasive paper or sanding belt to achieve a perfect and flawless product surface.

If the surface to be polished is relatively rough, such as metal polishing, mahogany furniture polishing, paint polishing, wall polishing, etc., because the surface structure of these objects is relatively rough and the grinding particles are large, it is suitable to choose dry sandpaper with a backing layer, because the sand particles of dry sandpaper are coarser and harder than those of water sandpaper. The particles of the sand particles and the particles on the surface of the object match each other, resulting in a higher grinding power and the ability to quickly grind a relatively smooth spherical surface. If you are grinding PVC circuit boards, mobile phone cases, precision instruments, etc., because the grinding particles on the surface of the object are smaller and require higher precision, especially for precision machining and industrial grinding, it is suitable to choose water sandpaper with a relatively thin paper base and fine sand particles. Water sandpaper can be used for wet sanding, while dry sandpaper cannot be used for wet sanding due to the backing layer and adhesives.

Features of water sandpaper

Water sandpaper can be wet sanded without dust damage and without dust explosion risks. The polishing quality is higher than that of ordinary dry sandpaper. When water sanding, the surface of the abrasive paper is not easily blocked, and the abrasive paper has a long service life. Waterproof sandpaper has relevant products with grit sizes ranging from P60 to P5000, while the finest grit size of ordinary dry sandpaper is around P1000. Water sandpaper is particularly suitable for fine-grained high-precision polishing. Fine grit water sandpaper has a higher cost performance compared to other precision grinding materials, and its price is relatively affordable. It can be used for wet sanding and dry sanding, making it widely applicable.
