Do you know about three-layer and five-layer composite materials? Do you know its advantages? Do you know what it is used for? Don’t worry, the editor will explain it to you below.
In order to give full play to the characteristics of the materials and maximize their strengths and avoid weaknesses, two or more materials with their own characteristics can be processed into a filter material. This filter material is called a composite filter material.
In view of the different forms of materials used in three-layer and five-layer composite materials, they can be divided into two types: material composite and structural composite.
Material composite is a composite method that uses two or more materials to produce woven filter materials or non-woven filter materials using woven or non-woven processes.
For example, some high-temperature resistant short synthetic fibers and short glass fibers are mixed, a fiber mesh is made using a non-woven process, and the fiber mesh is needle-punched onto a glass fiber base cloth to make a glass fiber composite mat.
The addition of synthetic fibers increases the entanglement strength of the fibers in the needle felt and the bonding strength between the felt layer and the base fabric, increases the density of the needle felt, and improves the filtration performance of the needle felt.
However, if the added synthetic fibers have low temperature resistance, the overall temperature resistance of the needle felt filter material will be sacrificed.
According to the different high-temperature resistant synthetic fibers added, the material composite needle felt can be divided into P84 glass fiber composite needle felt, PTFE glass fiber composite needle felt and Nomex glass fiber composite needle felt.
