PTFE Sintering Temperature Out of Control
Sorun Belirtisi
PTFE sintering temperature below 360℃ gives insufficient product strength, above 400℃ decomposes, and the temperature window is difficult to grasp.
Neden Analizi
PTFE sintering temperature of 360~380℃ fully melts the resin (melting point 327℃); below the range fusion is insufficient; exceeding 400℃ decomposes and releases harmful substances; furnace temperature uniformity and temperature measurement accuracy affect the actual temperature.
Çözüm
①Control sintering temperature at 360~380℃; ②Strictly prohibit exceeding 400℃; ③Multi-point temperature measurement and calibration of furnace temperature; ④Consider temperature gradients for large products and extend time.
Temel Çıkarım
The 360~400℃ window of PTFE sintering temperature is the process core; temperature uniformity needs equipment guarantee; the decomposition red line concerns safety.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
