Prepared to choose PTFE Sheet? That is fine. But hold off for just a second. Has your current coating really failed you?
The answer you’ll discover is in understanding friction and wear.
PTFE, also called polytetrafluoroethylene, surpasses many of the qualities of other thermoplastics.
Predicated on its relatively low modulus value, any surface asperities of PTFE will measurably deform under load. This means higher loads can produce lower friction.
Of course, coefficients of friction will rise with increasing temperature. Mostly the outcome of binder choice within the coating, so be sure you can recognize your temperature requirements. Drag can raise substantially, after you accomplish upper limits of continuous use, melting point, or glass transition temperature.
Sliding wear is ordinarily measured by material loss with time. So consider both of these primary mechanisms for wear: adhesive wear and abrasive wear. Between the two, adhesive wear may remain preferable.
How will you distinguish between both forms of wear? Well, if it is adhesive wear, you need to see developing fine powders at the software between the fluoropolymer coating and metal counter face. It is a great indication that surfaces are wearing the method that they should. However, phenomena like deep corrugations, grooves, or gouges within the coating will quickly indicate pressure rate limits of the stuff have been violated. Generally, also, assuming the surroundings stays unchanged, abrasive wear happens rapidly. At Times, failure is catastrophic and instantaneous.
