Description

Technical Field

[0001] The invention relates to the technical field of polytetrafluoroethylene sealing gasket production, in particular to a device and method for processing creep-resistant expanded polytetrafluoroethylene sealing gaskets. Background Art

[0002] Polytetrafluoroethylene is a high molecular compound containing fluorine atoms in the main chain of the molecule. The F atoms in the PTFE molecule cover the C-C bond and the C-F bond has high bond energy and is particularly stable, with good chemical stability. The F atoms in the PTFE molecule are symmetrical, and the two elements in C-F are covalently bonded. There are no free electrons in the molecule. Since the PTFE molecule has an inert fluorine-containing shell outside, it has outstanding non-stick properties and a low friction coefficient.

[0003] Existing polytetrafluoroethylene sealing gaskets have certain drawbacks when used. First, when processing polytetrafluoroethylene sealing gaskets, the electromagnetic roller is not convenient to move and adjust, resulting in the inability to adjust the gap between the two rollers, affecting the processing quality of the sealing gasket. Secondly, when the electromagnetic roller rotates, there are no protective facilities around it, which will endanger the life safety of the surrounding workers. After the gasket is formed, it is not convenient to cut it, affecting the production efficiency. Finally, due to the poor heat dissipation inside the pressing machine, the service life of the internal motor is reduced, which slows down the temperature of the electromagnetic roller and affects the efficiency. For this reason, we propose a creep-resistant expanded polytetrafluoroethylene sealing gasket processing device and method. Summary of the invention
