There are many types and uses of our common industrial brushes, which are divided into dust removal and cleaning, grinding and polishing, dust-proof transportation, paint lamination, and other applications. According to the appearance, it can be divided into brush roller, spring brush, brush wheel, disc brush, strip brush, plate brush, special-shaped brush, etc. Industrial brushes for different applications have different hardness selections for industrial filaments. Generally speaking, the selection is based on the material of the filaments.
The hardness of industrial brush wire materials is from hard to soft: metal wire > abrasive wire > rayon wire > natural wool. The metal wire brush is mainly used for surface derusting and deburring of metal materials and needs to have good hardness. and wear resistance. The abrasive wire is made of silicon carbide, alumina, diamond, and other materials added to the plastic. Compared with metal wire, it is more flexible and elastic. It is often used for grinding and polishing in the furniture and textile industries. There are many kinds of plastic wire materials, such as nylon, PBT, PP, PET, etc. The hardness is arranged from low to high. Compared with metal wire and abrasive wire, the bending recovery is better and the service life is longer. It is suitable for household cleaning brushes. and general industrial brushes. Commonly used natural wool materials include: bristle, sisal, horsehair, wool, etc., the material is relatively soft, animal wool usually has a tapered end, suitable for paintbrushes, paintbrushes, bath brushes, and precious metal surface polishing.
Therefore, the choice of industrial brush wire hardness still needs to be selected in combination with the use and use environment of the product, and it must not be one size fits all. Most of the bath brushes made by our company use boar bristles, and some are made of nylon according to customer requirements, but for dishes cleaning brushes, we usually use sisal fiber and palm fiber.
