Silicon Carbide Sandpaper Roll: Efficient Grinding, Precise Polishing

Silicon Carbide Sandpaper Rolls are a type of sandpaper product that uses silicon carbide (SiC) as an abrasive. They feature high hardness, high wear resistance, high corrosion resistance, and high thermal stability, making them widely used in various industrial fields. The main component of silicon carbide sandpaper rolls is silicon carbide, an inorganic material synthesized from carbon and silicon, also known as carborundum. Silicon carbide possesses high hardness, high temperature resistance, corrosion resistance, and good chemical stability, which allows it to perform excellently as an abrasive. Silicon carbide sandpaper rolls can be classified into different grades based on grit size, such as 40#, 60#, 80#, 120#, 150#, etc. The smaller the number, the coarser the sandpaper, suitable for initial grinding; the larger the number, the finer the sandpaper, ideal for fine polishing.

Manufacturing Process of Silicon Carbide Sandpaper Rolls

• Preparation of Silicon Carbide Abrasive Material: Mix natural silica with carbon at high temperature to produce silicon carbide through a chemical reaction.

• Preparation of the Substrate: Choose suitable fiber materials (such as cellulose, fiberglass, etc.) as the substrate for the sandpaper.

• Coating the Abrasive Material: Coat the substrate with silicon carbide abrasive material, followed by drying and curing.

• Processing and Cutting: Process and cut the substrate coated with silicon carbide abrasive material to make silicon carbide sandpaper roll.

Advantages of RMC ABRASIVE Silicon Carbide Sandpaper Rolls

High Hardness and Wear Resistance

Silicon carbide's high hardness characteristic allows silicon carbide sandpaper rolls to quickly remove surface layers and deformation layers of materials during grinding, improving grinding efficiency. Moreover, its wear resistance ensures that the sandpaper maintains stable grinding performance over prolonged use, extending its lifespan.

Fine Polishing

In the assembly and maintenance of electronic products, small parts often need to be polished to a fineness of less than 0.5um. With its fine abrasive grains and stable grinding performance, silicon carbide sandpaper rolls can easily achieve this goal, ensuring the quality and performance of electronic products.

Wide Applicability

Silicon carbide sandpaper rolls are suitable for grinding a variety of materials, including metals, wood, coatings, rubber, etc. Its powerful grinding capability allows it to quickly achieve the desired surface finish when handling these materials.
