Do you know enough about the choice of brush material? _common problem

Brushes are generally divided into two categories: civil and industrial. Civilian brushes refer to brushes used in our daily life and operations; such as toothbrushes, paint brushes, household cleaning brushes, makeup brushes, various brushes for cleaning and removing sharp bristles, etc. The application range of industrial brushes covers almost all industries, such as elevators, rail transit, cabinets, industrial doors, etc. Its main purpose is cleaning, dust removal, polishing, etc. in the industrial production process. There are two major types of brush materials in the industry: natural wool and man-made fiber materials. How much do you know about this aspect that can be subdivided into different materials? Let me give you a brief introduction today: Natural wool: 1. Pig bristles: Pig bristles are similar to human hair, from root to end from thick to thin. This feature makes the bristles good elasticity; common bristles color It is brown (white) or black. The durability and water resistance of bristles are excellent, as well as anti-static, high temperature and acid-base resistance. 2. Nylon 66 (PA66): Compared with nylon 6, nylon 66 is slightly better in terms of hardness, recovery and abrasion resistance at the same wire diameter, and its temperature resistance can reach 150 degrees Celsius. 3. Nylon 612 (PA612): Nylon 612 is a relatively high-quality nylon yarn with low water absorption, and its recovery and abrasion resistance are better than nylon 66. In addition, nylon 612 has anti-mold and antibacterial properties. The brush wheels and brush strips made of nylon 612 are often used in food, medical, and electronic related industries. 4. Abrasive nylon: Abrasive nylon is a synthetic filament made of nylon 6 or nylon 612 as the raw material for brush filaments and silicon carbide (SIC) or alumina (AO) abrasive particles. It is also called abrasive filament or abrasive filament in the industry. The finished brushes have the characteristics of wear resistance, and there are many kinds according to the wire diameter and the number of meshes. 5. PP: The characteristic of PP**** is that the density is less than 1. When testing the wool material, several of them can be placed in the water. If it floats on the water surface, it can be preliminarily judged as PP material; the cross-section of PP wool is oval; in addition, , PP has poor elasticity and is difficult to restore to its original shape after repeated bending; it can heat up to 120 degrees Celsius. 6. PET: PET's durability and high temperature resistance are similar to nylon; besides that, PET also has good resistance to acids and alkalis, alcohol, gasoline, benzene, and most cleaning solvents. It also has considerable antibacterial properties and is not easy to mold. 7. PBT: PBT wool has the advantages of acid and alkali resistance, oil resistance, and solvent resistance, but it is easily hydrolyzed at high temperatures. After reading the above introduction, do you know a lot about brushes? It looks like a small brush, there is indeed a lot of knowledge, you can choose the right material according to your needs, play the role of the brush, and bring more convenience to life.
