The ordinary abrasive belt in the back-only a layer of sand, sand blunt, the life of the abrasive belt end. Accumulation of abrasive belt is backing the multi-layered sand (ie accumulation) of abrasive belt, this belt life can be greatly extended. The accumulation of abrasive belt is the development trend of the coated abrasive.

The waterproof sandpaper also known as water mill sandpaper or water sandpaper, use flooding sanding or grinding in water is named, waterproof sandpaper on waterproof paper or water-resistant paper treated substrate to paint or resin binder , corundum or silicon carbide abrasive firmly glued to the base body made of an abrasive, its shape sheet-like and roll two. Its characteristics are: 1. Using linkage line production, high efficiency; 2. The waterproof sandpaper varnish as a binder, drying time, the its drying method commonly used to hang drying; 3. Waterproof sandpaper generally finer granularity of our water sandpaper from P80, fine-grained and metallographic sandpaper of grain aromatic convergence. 4. Waterproof sandpaper is generally polished operating under aqueous conditions, so the dust is less labor conditions.

Water sandpaper polished metal or non-metal workpiece and the surface of the water or oil. Cleaning the bathroom to use, making models with more. Dry sandpaper coated with an antistatic coating made of high-grade products, synthetic resin binder silicon carbide abrasive bonded latex top. Has the advantage of anti-blocking, anti-static, softness, and high wear resistance. Choose from a variety of fineness suitable for polished metal appearance, putty and coating. Dry sandpaper is generally used in a specially made of kraft paper and latex paper, made from natural and synthetic resin as a binder, state-of-the-art high electrostatic sand-planting technology from manufacturers, high grinding efficiency of this product, easy to stick crumbs and other characteristics suitable for dry grinding. Widely used in furniture, decoration and other industries, especially coarse grinding A smaller gap between the water sandpaper it sand smaller grind Unqualified, Unqualified and water is flowing out and water use thinner sandpaper dry grinding Unqualified Unqualified also larger gap will remain in the sand, so that the the sandpaper surface becomes light to reach this effect and dry sandpaper will not be so troublesome larger gap between the sand grinding out it grinding process in the fall due to the large gap causes Unqualified, so it does not need and water use. thickness that depends on what you want to sanding how slightly, water sandpaper worn slower, but the more light (the finer the water of the mill the slower sandpaper Koshihikari) dry sandpaper faster but but grinding out thick (a thicker dry sandpaper grinding the faster the more coarse) If you do not wear much on water sandpaper slightly, if you want to wear a lot of , then on the first dry sandpaper worn sandpaper to polish slightly with water (also depends on what you want to polish it slightly). yourself watching yourself can be kind of took the kind of forget
