Process Analysis of PTFE Membrane Structural Materials

The overall structure of PTFE building film material includes glass fiber base cloth and tree two parts, the inner layer of glass fiber base cloth is mainly to enhance the performance of the effect, reasonable selection of raw materials can ensure its tearing and tensile properties and other mechanical properties of good; The outer part of the resin structure can ensure its overall heat resistance, wear resistance, aging resistance and good insulation.

For example, when the actual selection of glass fiber base fabric material is mainly based on the nature of the film material to choose. For example, the flexible coating of PTFE building film material is a composite material, and the glass fiber base cloth is mainly used as a skeleton structure that carries external force inside, usually the material with high tensile strength and high temperature resistance is selected, which will directly affect the final film forming effect.

 

The processing process of PTFE building film material is simply to use the impregnated coating process method, and the polytetrafluoroethylene resin (PTFE resin) is smeared on the surface of the glass fiber wiki cloth and finally processed and synthesized.

 

The specific process is to apply PTFE resin emulsion on the glass fiber base cloth after heat treatment, and then carry out impregnation treatment, drying treatment, baking treatment, sintering treatment, cooling treatment, repeat the above treatment process many times, and finally obtain the finished product
