PTFE Static Electricity Problem
Problem Phenomenon
PTFE products carry extremely high static electricity, adsorb dust, and cannot be used in electronic and cleanroom occasions.
Cause Analysis
PTFE has excellent electrical insulation but sintered products themselves carry extremely high static electricity; insulation makes static electricity unable to discharge and accumulate; dust adsorption affects cleanliness; in some occasions static electricity is a safety hazard.
Solution
①Add antistatic materials to make antistatic products; ②Grounding and ionized air assistance; ③Select antistatic grades for cleanroom occasions; ④Include static electricity detection in inspection.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PTFE's excellent insulation is accompanied by static electricity troubles; antistatic modification is the premise of application expansion; occasion assessment determines material selection.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
