PTFE ityhubhu

PTFE ityhubhuFeatured Umfanekiso
  • PTFE ityhubhu
  • PTFE ityhubhu

I-PTFE yayiyi-fluoropolymer yokuqala efunyenweyo, kwaye ikwayeyona nto inzima ukuyiqhuba. Ekubeni iqondo lokushisa lokunyibilika lingamadigri ambalwa ngaphantsi kweqondo lobushushu, alinakunyibilikiswa. I-PTFE ilungiswa kusetyenziswa indlela ye-sintering, apho izinto zifudunyezwa kwiqondo lobushushu elingaphantsi kwendawo yokunyibilika ixesha elithile. Iikristale ze-PTFE ziyacoleka kwaye zinxibelelane, zinika iplastiki ukumila kwayo efunekayo. I-PTFE yayisetyenziswa kushishino lwezonyango kwangeminyaka yoo-1960. Namhlanje, isetyenziswa ngokuqhelekileyo kwiintshayelelo ze-sheath kunye ne-dilators, kunye nokuthambisa i-catheter liners kunye ne-heat shrink tubing. I-PTFE yilayini yecatheter efanelekileyo ngenxa yokuzinza kwayo kweekhemikhali kunye ne-coefficient ephantsi yokukhuhlana.
