Concept and classification of brushes and purchasing knowledge

1、 Concept of brush
Many people are confused about what a brush is, but when it comes to toothbrushes, laundry brushes, shoe brushes, dish brushes, pot brushes, and even paint brushes, everyone feels familiar with them. In fact, these are commonly used tools in people's daily life, and they are also the earliest form of use of brushes. However, for a long time, people have been accustomed to using them, often ignoring them themselves.
Although a brush is also an object that belongs to the category of erasers, an eraser can be made into various shapes and can have various colors and flavors, but a brush is quite different from an eraser. The brush only has a single rectangular shape, and the rectangular shape is too straight and rigid, and it is not beautiful, even ugly. And the flavors of all shapes and colors are not to mention. Have you ever seen a scented brush? Of course not, and it is impossible for any brush to have a fragrance. If there is any real smell, it can only be counted as the very, very pungent dust smell left by the chalk written on the blackboard and the brush cleaned up!
2、 Classification of brushes:
According to the classification of the place of use, brush can be divided into civil brush and industrial brush
1. Civil brush: Mainly used for cleaning and other purposes in daily life.
Civil brush mainly includes: kitchen brush, shower brush, shoe brush, toothbrush, pot brush, laundry brush, coat brush, bathtub brush, bottle brush, glass cleaning brush, test tube brush, pet brush, massage brush, barbecue brush, bath brush, stainless steel sanitary brush, toilet brush, sponge window brush, shoe brush, clothes brush, roller brush, wall brush, paint brush, car brush, snow brush, etc
2. Industrial brush: Mainly used in cleaning machinery, food processing industry, glass ceramic industry, textile printing and dyeing industry, metal processing industry, polishing, cleaning, dust removal, rust removal, etc. Industrial brush mainly applies in four areas: dust prevention, polishing, cleaning, and grinding.
3、 Some common sense to master when purchasing a brush
Brush is indispensable in modern industrial production and is a necessary accessory device for certain mechanical equipment. To play a crucial auxiliary role in promoting the development of industrial production, the following factors should be considered when purchasing a brush:
1. Outer diameter of brush body and coaxiality of hole
2. Tensile strength of abrasive wire
3. Brush roller brush wire density
4. Normal service life
5. Abrasive and Roughness
6. Whether the brush body has hair loss
7. Surface finish, elasticity, and water absorption of the water absorption roller
8. Material used for brush wire and brush body
Note: Different specifications of the same type of brush or brush roller generally have different uses. Some can be deburred, some can be polished and cleaned with copper foil, and some can be used for polishing with solder. The material selection of the brush wire must be reasonable and appropriate. The correct selection of industrial brush wires requires first studying the physical properties of the material to be treated, such as the surface finish and hardness of the material, to determine the material used for the brush wire; Secondly, select the appearance of the brush according to the working conditions; The latter is to determine the brush specification and rotational speed according to the process parameters. In general, the larger the diameter of a circular brush, the better its effect. Under the same diameter condition, the shorter the brush wire, the stronger the grinding force. The longer the brush wire, the weaker the grinding force.
