Coated abrasive tool is a kind of abrasive tool processed by matrix, binder, and abrasive. It has good flexibility and adaptability. It is divided into three types: manual, semi-manual and machine. Hand-made products mainly include sheet-type dry sanding cloth, dry sanding paper, and water sandpaper that we see every day. Semi-manual products are mostly special-shaped products, including page whee...

Ground, Honed, Polished. Ground concrete has a flat appearance with no or very slight reflection (below 50 grit resin). Honed finish has a matte appearance and/or slight clarity of reflection that has a low or medium sheen (100-400 grit resin). Semi-polished finish has some clarity of reflection and medium to high sheen (400- or 800-grit resin). Polished finish has a glass-like finish and reflecti...

Polished concrete is probably the most durable and the most cost-effective flooring options. It is dust free, stain-resistant, slip-resistant and easy to maintain. In addition, it has increased light reflectivity. The life expectancy of a concrete floor will far surpass that of most other flooring surfaces, making it a common choice for retail stores, warehouses, manufacturing facilities, restaura...

Choosing the proper floor grinding and polishing machine is critical for your bottom line, therefore a good understanding of the different options is necessary. Grinding machines are used to prepare, level, polish, and remove glues and coatings on concrete surfaces. They are often called diamond grinders or diamond polishers because they use diamond abrasives to process the floor. There are two ma...

Technology has created concrete coatings that are meant to last. This makes removal time-consuming and difficult, but not impossible. There are several techniques you can choose from to take off a coat of sealant, paint or epoxy from a concrete surface. There are two basic methods for removing concrete coatings: mechanical and chemical. Mechanical methods include grinding, sandblasting and sanding...

Improve the bonding strength between abrasive and abrasive bond and the coating acts as a bonding bridge between them. Slow down the thermal shock. The metal coating conducts heat more slowly than the superhard abrasive. The grinding heat is buffered by the coating and then transferred to the resin bond in contact with the abrasive particles, so as to prevent the resin bond from burning out due to...

Diamond is made of graphite as raw material, some metals or alloys as catalyst, under high temperature (1000~2000℃) and high pressure (557~608Mpa), the graphite structure is transformed into diamond structure. Diamond is the hardest substance known, with high compressive strength, good thermal conductivity, chemical stability, wear resistance, and strong cutting ability. Diamond can be divided int...
