Embodiment approach
[0044] As an embodiment of the present invention, the concentration of the mixed solution in the immersion device is 90mol / L; the temperature of the mixed solution in the immersion device is between 75-90°C;
[0045] The concentration of PTFE dispersion directly affects the surface finish, flatness, thickness and resin content of the product. When the concentration is too high, the thickness after each impregnation will be large, which will make the coating on the fiber cloth too thick and make the Cracks are produced on the surface of the fiber cloth, and the concentration of the mixed solution is 90mol / L when the present invention is dipped, so as to prevent the occurrence of an over-thick coating on the surface of the fiber cloth, thereby affecting the quality and quality of the fiber cloth, because the temperature of the mixed solution is between Between 75-90°C, so that the mixed solution can be better impregnated on the surface of the fiber cloth, so as to avoid the exces...
