[0028] Working principle: After determining the tempering temperature and holding time, select the appropriate tempering temperature and holding time according to the characteristics and requirements of the specific material. Adjust the speed according to the hardness and thickness of different films. Pull the elastomer film into the tempering furnace to ensure that the film is laid flat. Gradually increase the temperature of the tempering furnace until the tempering temperature is reached. The heating rate should be controlled within the range that the material can withstand to avoid uneven heating and damage caused by too fast heating. After reaching the tempering temperature, keep the temperature constant for a period of time. This period of time depends on the material thickness, size and specific requirements, usually ranging from a few minutes to a few hours. Gradually reduce the temperature of the tempering furnace to room temperature or other specified temperature. The cooling rate should be slow to avoid the generation of new stresses. Avoid sudden changes from high temperature to low temperature to avoid uneven shrinkage and deformation of the material. After cooling is completed, the tempered elastomer film is removed and cleaned. The tempered film is inspected for quality, including evaluation of appearance, size, elasticity and other properties.
