Description

Technical Field

[0001] The utility model relates to the technical field of needle felt coating, and specifically relates to a stainless steel fiber needle felt coating device. Background Art

[0002] Stainless steel fiber needle felt can be coated with various types of films, including polytetrafluoroethylene (PTFE), polyimide, polyester, etc. The performance advantages of the needle felt after coating are reflected in the following aspects: increasing the wear resistance of the filter medium. The coated stainless steel fiber needle felt has higher folding resistance, which can enhance the resistance of the filter medium to wear particles and improve the filtration efficiency. The stainless steel fiber has high hydrophobicity. After coating, it can enhance its barrier to liquids and enhance the temperature resistance of the filter medium. Some coating materials such as polyimide have good temperature resistance and can extend the service life of the filter material.

[0003] However, stainless steel fiber is a kind of metal conductive fiber. After stainless steel fiber is mixed into the fiber layer, due to the hardness of stainless steel fiber itself, there is a possibility that stainless steel fiber will pierce the PTFE film when coating the surface of the fiber layer. Damage during the coating process will lead to reduced production efficiency and extended production time. The damaged PTFE film needs to be replaced, which increases the cost of coating. The damaged film will affect the overall performance and service life of the product and reduce product quality. Therefore, we propose a stainless steel fiber needle felt coating device to ensure product quality and performance. Utility Model Content
