Characteristics and Classification of Sandpaper and Abrasive Cloth

Abrasive paper and abrasive cloth are made of high quality nylon fiber, adhesive corundum, silicon carbide and other abrasives through the nonwoven process. They are new abrasive products with three-dimensional mesh structure.

These products were invented in the 1970s. After several decades of development, nonwoven grinding pieces have been formed at present. Nonwoven grinding wheels and rollers, grinding belts with back bases and discs, and special fiber grinding products are widely used in the polishing of metal and non-metallic materials, burr elimination, removal of oxidation film, and line decoration.

Ⅰ. Characteristics of the abrasive paper and abrasive cloth

Compared with traditional abrasive products, the characteristics of abrasive paper and abrasive cloth are as follows:

1. With good elasticity and mild grinding force, the abrasive paper and abrasive cloth can dress the surface quickly while maintaining the dimension integrity of the workpiece.

2. In the processing, the effective heat dissipation greatly avoids workpiece deformation and blackening caused by overheating.

3. The three-dimensional network structure made of high quality nylon fiber material ensures good water resistance, oil resistance, and clogging resistance.

4. Long service life, high cost performance, and time and labor saving.

As an ideal surface treatment tool, abrasive paper and abrasive cloth have been widely used in factories and family DIY activities in developed countries in Europe and the United States, and they are also accepted by more and more industries in China.

Ⅱ. Classification of the abrasive paper and abrasive cloth

1. Non-woven grinding piece

This is the most popular non-woven abrasive product, also known as industrial clean cloth. It is usually used with machine or by hand. Non-woven grinding piece The non-woven grinding piece is convenient, fast, and efficient, and greatly reduces the complexity of surface treatment. It is widely applied in stainless steel and other alloy hardware products, the polishing, burr removal, and line decoration of wood furniture, and surface treatment in mechanical, electronic and ceramic industries.

2. Non-woven grinding wheels and rollers

These abrasives products mainly include insert type wing wheels, drawing wheels, laminated fiber wheels, convolute wheels, non-woven brush roller, etc.

The application range of wing wheels is wide, and the specifications and models are complete. Wing wheels are used in hardware industries such as watches, door bolts, handles and locks, as well as in the line treatment of high-end wood products, because they can adapt to grinding irregular surfaces and make uniform grinding patterns. This kind of processing technology has been quite mature now.

There are two kinds of drawing wheels: composite abrasive paper and individual non-woven abrasive cloth. They are usually used with electric polishing and drawing tools in the surface polishing and drawing of stainless steel, alloy, glass, hard plastic, etc. The wheels are widely used in industries such as automobile, kitchen and bathroom, elevator, and glass furniture.

Laminated fiber wheels have different hardness. The fiber wheels made of high-quality fibers are strong and durable, and the sand grain is beautiful and uniform. They are usually operated by machine. Laminated fiber wheels are the most commonly non-woven grinding wheels at present, and they are used in polishing, drawing and deburring of stainless steel, copper and alloy products.
