Waxaan ku hawlannahay soo saarista mashiinka cajaladda polymer PTFE, kaas oo sidoo kale loo yaqaan mashiinka cajaladda PTFE, Mashiinka cajaladaha dhejiska, in ka badan 20 sano, hadda sharaf ISO9001 iyo shahaadada CE ee la helay.Waxaan nahay kuwa ugu horreeya ee soo saara mashiinka PTFE ee Shiinaha.Ma aha oo kaliya inaan ku siin karno khadka wax soo saarka, laakiin sidoo kale waxaan ku siin karnaa alaabta ceeriin.Mashiinnada ugu muhiimsan waxaa ka mid ah: Mixer, Calender, Slitter, Machine Pressing, Foornada, Mashiinka wax duubista iwm.
Baaxadda ugu dambeysa ee cajalad shaabad ah oo dunta PTFE:Dhumucda: 0.05-0.3mm ama ka badan (sida loo baahan yahay);Ballac: 8mm, 10mm, 12mm, 19mm, 25mm ama kuwa kale, sida waafaqsan shuruudahaaga;Dhererka: 8m, 10m, 12m, 15m, 18m, 20m, 25m, 40, etc.. sida waafaqsan baahidaada.
PTFE waxaa si weyn loogu isticmaalaa baahiyo kala duwan, sida: anti-acid iyo dareerayaasha organic, taas oo lafteeda aan lahayn wax sun ah dadka, laakiin mid ka mid ah alaabta ceeriin ee loo isticmaalo habka wax soo saarka ee ammonium perfluorooctanoate (PFOA) ayaa loo arkaa inay u badan tahay inay leeyihiin. saamayn kansarka.
Unugyada qaraabada weyn ee PTFE, kan hoose sida boqolaal kun, halka mid ka sarreeya uu gaari karo ilaa hal milyan ama ka badan (degree of polymerization of 104 orders of magnitude, halka polyetylen kaliya 103).Degree of crystallinity guud ahaan waa 90 ilaa 95%, heerkulka dhalaali waa 327 ~ 342 ℃.Unugyada Molecule CF2 ee PTFE waxay habeeyaan qaabka zigzag, sababtoo ah radius fluorine oo ka weyn hydrogen, markaa cutubyada CF2 ee ku xiga kama gudbi karaan jihada saxda ah, laakiin waxay sameeyaan silsilad qalloocan, atom fluorine oo daboolaya ku dhawaad dhammaan dusha silsiladda polymer.Qaab dhismeedka molecular wuxuu sharxayaa sifooyinka kala duwan ee PTFE.Heerkulka ka hooseeya 19 ℃ si loo sameeyo 13/6 helix;Marxaladda kala-guurka ee 19 ℃, wax yar kala bixi molecular si aad u samayso 15/7 helix.
In kasta oo kaarboonka perfluorocarbon - bond bond iyo carbon - bonds fluorine ay jabeen baahida loo qabo in la nuugo tamarta 346.94 iyo 484.88kJ/mol, laakiin tamarta depolymerization PTFE waxay dhalinaysaa 1mol tetrafluoroethylene kaliya waxay u baahan tahay 171.38kJ.Markaa pyrolysis-ka, PTFE inta badan depolymerizate tetrafluoroethylene.PTFE ee 260,370 iyo 420 ℃ heerka dhimista miisaanka (%) waxay ahaayeen 1×10-4, 4×10-3 iyo 9×10-2 saacadiiba.
