Water Emery Sheet: The Industrial Beautician

The gaps between the grit particles of water emery sheet are smaller, and the debris produced is also smaller. When used together with water, the debris will flow out along with the water. Therefore, it should be used with water. If you use water emery sheet for dry sanding, the debris will adhere to the gaps between the grit particles, causing the sandpaper surface to lose its sharpness and grinding power. Thus, it does not achieve its intended effect. The sandpaper grit numbers range from 80 to 7000; the higher the number, the finer the sandpaper, and the smoother the resultant surface.

Characteristics of Water Emery Sheet

• The polishing quality is higher than that of regular dry sandpaper. When sanding with water, the sandpaper surface is less likely to get clogged, and the sandpaper has a longer lifespan.

• Water emery sheet has a wide range of grit sizes, from P60 to P5000, whereas regular dry sandpaper typically only goes up to around P1000. Water emery sheet is particularly suitable for high-precision polishing with fine grits.

• Fine-grit water emery sheet offers a higher cost-performance ratio compared to other precision grinding materials. It is relatively inexpensive and can be used for both wet and dry sanding.

Why Water Emery Sheet Needs Water

This depends on the different types of adhesives. The adhesive for water emery sheet is paint or resin, while the adhesive for dry sandpaper is animal glue. Water emery sheet has smaller gaps between the grit particles, and the debris produced is also smaller. When used with water, the debris will flow out with the water, so it should be used with water. If you use water emery sheet for dry sanding, the debris will remain in the gaps between the grit particles, causing the sandpaper surface to become smooth and lose its intended effect. Generally, for sanding above 800 grit, water emery sheet is required.

Role and Usage of Water Emery Sheet

Sandpaper plays a significant role in model making, such as removing parting lines and smoothing the cut marks on gates. It can also be used with fine-grit sandpaper to remove oxidation layers and reveal the original metallic luster. Using oil while sanding can produce a softer sheen.

Water emery sheet is like an industrial beautician. From computers to teacups and leather shoes, sandpaper is indispensable. It is through the use of tools that we have a colorful world. Woods, leather, and metals cannot become products or be used directly without being cut, processed, reshaped, and polished. Polishing and grinding are key steps to perfecting a product. Therefore, carefully selecting the appropriate water emery sheet is essential for achieving a flawless surface.

For grinding rough surfaces such as redwood furniture, paint sanding, and wall sanding, where the surface structure is rough and the particles large, a coarser dry sandpaper with a layer of particles on its surface is suitable. Dry sandpaper is rougher and harder than water emery sheet, allowing it to quickly achieve a smooth effect. For grinding surfaces like PVC circuit boards, phone casings, and precision instruments where the surface grinding particles are small and require high precision, especially for precision machining and manual grinding, a thinner paper base and finer grit water emery sheet is suitable. Dry sandpaper, which has a particle layer and glue, cannot be used with water for grinding.
