What are the four types of brushes commonly used in car washing machines

The car wash brush is a very important part of an automatic car wash machine, and it is also the only part that directly contacts the paint surface of the car. The quality of the brush directly affects the quality of the car wash. So what are the main categories of car wash brushes? Below, the editor of the car washing machine will explain the four common types of brushes used in car washing machines, hoping to be helpful to everyone.
1. Cloth brush:
The characteristics of this brush are good cleanliness, short service life, and easy coverage by sand. If the vehicle is not pre treated with a high-pressure water gun during the cleaning process, the sand and gravel on the body can easily wrap in the brush, leaving obvious scratches on the body.
2. Cotton brush:
High cleanliness and high moisture content. However, after the non-woven cotton material absorbs a large amount of water, the weight of the brush will increase exponentially. Accidents are prone to occur when using a small car wash machine. Brushes have been popular in China for less than two years and are gradually being abandoned by large manufacturers. Currently, they are mainly used in various large car washing equipment.
3. Fiber brush:
The brush is made of special polymer materials, which are soft and not easy to break, and can be processed into different colors. The color is very eye-catching during use. At present, there are two types on the market: silk shaped and sheet shaped. Among them, the shape of silk is made in China, and the durability and softness of the material are poor. Long term use can damage the brightness of the vehicle.
4. Foam brush:
Its characteristics are lightweight, high cleanliness, and good dehydration. Similarly, foam brush can be divided into domestic brush and imported brush. The household foam brush is cheap, loose, easy to break and has little contact with the car body, which will affect the cleanliness. Household foam brushes are basically processed into thin strips, which is not conducive to cleaning the dirty parts of vehicles. Imported foam brush is made of compact materials, with high wear resistance.
The Blue Sky Intelligent Car Wash Machine uses a polyethylene foam brush imported from Italy. According to the testing report of the Chinese quality management certification agency on the polyethylene foam brush, the surface coating of the test piece (similar to vehicle sheet metal parts) is affected between 0.3 and 0.4 for every 10 washes of the car μ Within m. The paint thickness of different models ranges from 120 to 180 μ Between m. The impact of polyethylene foam brush on car paint is less than the corrosion caused by acid rain and sediment, and can be ignored.
The above four points are all about the four common types of brushes used in car washing machines. Thank you for your understanding and support!
