Generally speaking, the key to the filter element lies in the filter material, and the key to selecting the filter material lies in the properties of the dust. Therefore, how to select the filter material according to the properties of the dust is the key to making the filter element. Here, the editor will introduce to you a good The filter material is ptfe coated material.
In order to increase the service life and increase the strength of the membrane, it is necessary to compound the PTFE membrane to various filter materials, such as various needle felts, woven fabrics, glass fiber, etc.
Due to the non-sticky nature of PTFE itself, it has high requirements for membrane compounding technology. Currently, there are two compounding methods: glue compounding and thermal compounding.
PTFE film-coated material is a new type of filter material formed by compounding a layer of polytetrafluoroethylene (PTFE) film on the surface of ordinary filter material.
This layer of film is equivalent to a “primary dust layer”. Material exchange is carried out on the surface of the membrane, and effective filtration can be carried out at the beginning of use.
The unique three-dimensional network structure of the film prevents dust from passing through, and there is no risk of pore clogging.
This type of filtering is called “surface filtering”.
The film-coated filter material can not only achieve near-zero emissions, but also because the film is non-sticky and has a small friction coefficient, the powder cake will automatically fall off, ensuring long-term stability of the equipment resistance, thus giving full play to the advantages of the bag dust collector. Ideal filter material choice.
It is a manufacturer of PTFE coating materials that specializes in R&D, production and sales.
