Three-layer and five-layer composite materials have high air permeability
Three-layer and five-layer composite materials are not simply mixing several materials together.
It has some characteristics that ordinary materials do not have. Let’s take a closer look below.
Three-layer and five-layer composites are a mixture.
It plays a great role in many fields and replaces many traditional materials.
Composite materials are divided into metal and metal composite materials, non-metal and metal composite materials, and non-metal and non-metal composite materials according to their composition.
According to its structural characteristics, it is divided into: ① Fiber reinforced composite materials.
It is composed of various fiber reinforcements placed in the matrix material.
Such as fiber reinforced plastics, fiber reinforced metals, etc.
②Sandwich composite materials.
It is composed of surface materials and core materials with different properties.
③Fine-grained composite materials.
Evenly distribute hard fine particles in the matrix, such as dispersion-strengthened alloys, cermets, etc.
④Hybrid composite materials.
PTFE composite material has a smooth surface and is resistant to chemicals. It is laminated to the surface of ordinary filter materials and acts as a disposable dust layer, trapping all dust on the surface of the membrane to achieve surface filtration.
It has unparalleled advantages over traditional filter materials.
PTFE composite materials have the characteristics of high peel strength, large air permeability, low resistance, and concentrated and uniform pore size distribution. The three-layer and five-layer composite materials are prepared using unique biaxial stretching technology, which can ensure the complete interception of bacteria and other impurities. At the same time, it has greater flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
