Ukuzibandakanya kwethu kumatshini weteyiphu we-PTFE wepolymer, okwabizwa ngokuba ngumatshini weteyiphu we-PTFE, umatshini weteyiphu we-Thread seal, ngaphezulu kweminyaka engama-20, ngoku uhloniphe i-ISO9001 kunye nesatifikethi se-CE esifunyenweyo.Singabantu bokuqala ukwenza i-PTFE Tape Machine e-China.Asikuko nje ukuba sikubonelele ngomgca wemveliso, kodwa sikwabonelela ngemathiriyeli ekrwada.Oomatshini abaphambili babandakanya: Umxube, iKhalenda, iSlitter, uShicilelo loShishino, i-oveni, umatshini wokusonga njl.
Uluhlu lwe tape yokutywina yomsonto wokugqibela wePTFE:Ukutyeba: 0.05-0.3mm okanye ngaphezulu (ngokwemfuno yakho);Ububanzi: 8mm, 10mm, 12mm, 19mm, 25mm okanye abanye, ngokwemfuno yakho;Ubude: 8m, 10m, 12m, 15m, 18m, 20m, 25m, 40, njl..ngokwemfuno yakho.
I-PTFE isetyenziswa ngokubanzi kwiimfuno ezahlukeneyo, ezifana nezi: i-anti-asidi kunye nezinyibilikisi zendalo, yona ngokwayo ayinayo ityhefu ebantwini, kodwa enye yezinto ezisetyenziswa kwinkqubo yokuvelisa i-ammonium perfluorooctanoate (PFOA) ithathwa njengenokuba nayo. impembelelo ye-carcinogenic.
Imolekyuli enkulu enxulumene ne-PTFE, enye esezantsi njengamakhulu amawaka, ngelixa iphakamileyo inokuya kuthi ga kwisigidi esinye okanye ngaphezulu (inqanaba lepolymerization yemiyalelo ye-104 yobukhulu, ngelixa i-polyethylene kuphela i-103).Iqondo lekristale lidla ngokuba ngama-90 ukuya kuma-95%, ubushushu obunyibilikayo bungama-327 ~ 342 ℃.Iyunithi ye-Molekyuli ye-CF2 kwi-PTFE ilungelelanisa ngobume be-zigzag, ngenxa yokuba i-athomu ye-athomu ye-fluorine inkulu kune-hydrogen, ngoko ke iiyunithi ezimeleneyo ze-CF2 azikwazi ukuwela ngokuthe ngqo ukuqhelaniswa, kodwa zenze ikhonkco elijijekileyo, i-athomu ye-fluorine egquma phantse yonke i-polymer chain surface.Esi sakhiwo semolekyuli sichaza iipropati ezahlukeneyo ze-PTFE.Kubushushu obungaphantsi kwe-19 ℃ ukwenza i-13/6 helix;inguqu yesigaba kwi-19 ℃, tyhila kancinci imolekyuli ukwenza i-15/7 helix.
Nangona i-perfluorocarbon carbon-carbon bond kunye ne-carbon-fluorine bonds zaphukile imfuno yokufunxa amandla 346.94 kunye ne-484.88kJ/mol, kodwa i-PTFE depolymerization energy yenza i-1mol tetrafluoroethylene ifuna kuphela i-171.38kJ.Ke kwipyrolysis, PTFE ikakhulu depolymerizate tetrafluoroethylene.I-PTFE kwi-260,370 kunye ne-420 ℃ izinga lokulahleka kwesisindo (%) laliyi-1 × 10-4, 4 × 10-3 kunye ne-9 × 10-2 ngeyure.
