Ukuhlanganyela kwethu ekukhiqizeni umshini we-PTFE polymer tape, owaziwa nangokuthi umshini we-PTFE tape, umshini we-Thread seal tape, iminyaka engaphezu kwengu-20, manje uhlonipha i-ISO9001 nesitifiketi se-CE esitholiwe.Singabokuqala abenza i-PTFE Tape Machine eChina.Asikwazanga nje ukukunikeza umugqa wokukhiqiza, kodwa futhi ukuhlinzeka ngezinto ezingavuthiwe.Imishini eyinhloko ihlanganisa: I-Mixer, Ikhalenda, I-Slitter, Umshini Wokucindezela, Uhhavini, Umshini Wokusonga njll.
Ububanzi bethayiphu yokugcina yophawu lwentambo ye-PTFE:Ubukhulu: 0.05-0.3mm noma ngaphezulu (ngokwemfuneko yakho);Ububanzi: 8mm, 10mm, 12mm, 19mm, 25mm noma abanye, ngokuvumelana nemfuneko yakho;Ubude: 8m, 10m, 12m, 15m, 18m, 20m ,25m, 40, njll..ngokwemfuneko yakho.
I-PTFE isetshenziswa kabanzi ezidingweni ezehlukene, njengalezi: izincibilikisi ezilwa ne-asidi neziphilayo, zona ngokwazo ezingenabo ubuthi kubantu, kodwa enye yezinto ezingavuthiwe ezisetshenziswa ekukhiqizeni i-ammonium perfluorooctanoate (PFOA) kubhekwa ukuthi kungenzeka ibe nayo. umphumela we-carcinogenic.
I-molecular enkulu yesihlobo se-PTFE, ephansi njengamakhulu ezinkulungwane, kuyilapho ephakeme ingafika esigidini esisodwa noma ngaphezulu (i-degree of polymerization yama-oda angu-104 wobukhulu, kuyilapho i-polyethylene ingu-103 kuphela).I-Degree of crystallinity ngokuvamile i-90 kuya ku-95%, izinga lokushisa elincibilikayo lika-327 ~ 342 ℃.Iyunithi ye-Molecule CF2 ku-PTFE ihlela ngesimo esimazombezombe, ngenxa yokuthi i-athomu ye-athomu ye-fluorine inkulu kune-hydrogen, ngakho amayunithi e-CF2 aseduze awakwazi ukuwela ncamashi ukuqondisa, kodwa akhe iketango elisontekile elisontekile, i-athomu ye-fluorine emboza cishe yonke indawo engaphezulu yeketanga le-polymer.Lesi sakhiwo samangqamuzana sichaza izici ezihlukahlukene ze-PTFE.Emazingeni okushisa angaphansi kuka-19 ℃ ukwenza i-13/6 helix;ukuguquka kwesigaba ku-19 ℃, vula kancane i-molecular ukuze yakhe i-15/7 helix.
Yize i-perfluorocarbon carbon – carbon bond ne-carbon – fluorine bond ephukile isidingo sokumunca amandla angu-346.94 kanye no-484.88kJ/mol, kodwa i-PTFE depolymerization energy ikhiqiza i-1mol tetrafluoroethylene idinga kuphela u-171.38kJ.Ngakho-ke ku-pyrolysis, i-PTFE ikakhulukazi i-depolymerizate tetrafluoroethylene.I-PTFE ku-260,370 kanye ne-420 ℃ izinga lokulahlekelwa isisindo (%) lalingu-1 × 10-4, 4 × 10-3 kanye no-9 × 10-2 ngehora.
