[0050] Experiment 1: The selected samples were kept at the same temperature for processing. Product A and Product B were tested at different heat pressing times. The glue of the products after heat pressing was removed with the same force. The time displayed at the final debonding was compared. Figure 2 As shown, the effect achieved by the raw material weight ratio adopted in Example 2 is better than the other two, and it can withstand a longer degumming time, so it is the best production ratio combination, and product A has better performance than product B, and the other two can also be used in production.
