Experimental study on high-temperature sealing of Ptfe filter bag stitching with adhesive coating

Contact person: Huang Qingbao Phone number: 18750925560

1、 Purpose: To solve the problem of ash leakage during the operation of the three needle suture of the filter bag.

2、 Experimental methods

Step 1: Use a sewn 100% PTFE material filter bag;

Step 2: Apply high-temperature resistant soft adhesive (capable of withstanding a temperature of 300 ℃)

Step 3: Set the oven to 290 ℃ for 90 minutes

Step 4: Check the sealing of the three needle suture and the morphological changes of the high-temperature resistant adhesive.

3、 Experimental conclusion

According to the above experimental steps, it is demonstrated that this high-temperature resistant soft adhesive can be baked for 90 minutes at a high temperature of 290 ℃. After removal, both the colloid and filter bag remain in their original state without significant changes. This also proves the feasibility of this sealing scheme for the three needle hole.

Experimental date: June 6th, 2016
