In the new era, new products will inevitably be born. This is the law and symbol of the development of the times.
Nowadays, three-layer and five-layer composite materials are constantly being improved through people’s efforts, and are gradually moving into higher fields.
Take applications in the cement industry as an example. Their high-temperature filter material products are mainly fiberglass cloth-coated filter materials, composite felt-coated filter materials and composite felt filter materials.
The mainstream filter material is a three-layer and five-layer composite material.
There are two forms of polytetrafluoroethylene dust removal filter bags: one is made of polytetrafluoroethylene fiber coated with other filter materials (polyphenylene sulfide fiber, P84 polyimide fiber, glass fiber, etc.) On the base fabric, the other is that both the coating and the base fabric are made of polytetrafluoroethylene fiber and processed into needle felt.
100% PTFE fiber filter bags provide better performance.
Despite its superior performance, the high price of polytetrafluoroethylene fiber is an obstacle that restricts its wide-scale promotion.
Three-layer and five-layer composite materials have played a great role in many fields, replacing 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: 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.
Sandwich composites.
It is composed of surface materials and core materials with different properties.
Fine-grained composites.
Evenly distribute hard fine particles in the matrix, such as dispersion-strengthened alloys, cermets, etc.
