| titleOfInvention | A kind of method of gamma-rays strong oxidizing atmosphere preparation ultrafine PTFE powder |
| abstract | The invention discloses a kind of methods of gamma-rays Strong oxdiative atmosphere preparation ultrafine PTFE powder, comprising: dry ground polytetrafluoroethylene (PTFE) raw material is placed in chilling in liquid nitrogen；The polytetrafluoroethylene (PTFE) powder that partial size is 100-1000 μm is ground into pulverizer again；Then it is put into the container of the automatic production line of Co 60 device；Ozone is first passed through into container on automatic production line, then spray hydrogen peroxide and carbon tetrachloride, again by being irradiated when Co 60 device after spray, irradiation dose 40-60KGy, irradiation time is determined according to the radioactivity size of Co 60 device；Automatic production line transports irradiated polytetrafluoroethylene (PTFE) powder outside radiation chamber；It is put into airflow comminution system, sufficiently crushing can be obtained partial size in 5 μm of superfine powder of polytetrafluoroethylene below.Method of the invention can reduce the energy level of polytetrafluoroethylene (PTFE) chemistry key opening through the above way, increase higher degradation efficiency and faster degradation speed under identical radiation level, to obtain the narrower polytetrafluoroethylene (PTFE) particle of average particle size distribution. |
