Timagwira ntchito yopanga makina a tepi a PTFE polima, omwe amatchedwanso makina a PTFE, makina osindikizira a Thread, zaka zopitilira 20, tsopano akulemekeza ISO9001 ndi satifiketi ya CE yopezedwa.Ndife oyamba kupanga PTFE Tepi Machine ku China.Osati kokha ife akanatha kukupatsani mzere kupanga, komanso kupereka zopangira.Makina akuluakulu akuphatikizapo: Chosakaniza, Kalendala, Slitter, Makina Osindikizira, Ovuni, Makina Okulunga ndi zina.
Mitundu ya tepi yomaliza ya ulusi wa PTFE:makulidwe: 0.05-0.3mm kapena kupitilira apo (malinga ndi zomwe mukufuna);M'lifupi: 8mm, 10mm, 12mm, 19mm, 25mm kapena ena, malinga ndi lamulo lanu;Utali: 8m, 10m, 12m, 15m, 18m, 20m , 25m, 40, etc..malinga ndi lamulo lanu.
PTFE imagwiritsidwa ntchito kwambiri pazosowa zosiyanasiyana, monga: anti-acid ndi zosungunulira za organic, zomwe sizikhala ndi poizoni kwa anthu, koma chimodzi mwazinthu zomwe zimagwiritsidwa ntchito popanga ammonium perfluorooctanoate (PFOA) amawerengedwa kuti ndi mphamvu ya carcinogenic.
Large wachibale molekyulu ya PTFE, m'munsi monga mazana zikwi, pamene apamwamba mmodzi akhoza mpaka miliyoni imodzi kapena kuposa (digiri polymerization wa 104 malamulo ukulu, pamene polyethylene yekha 103).Mlingo wa crystallinity nthawi zambiri ndi 90 mpaka 95%, kutentha kosungunuka kwa 327 ~ 342 ℃.Molekyulu CF2 wagawo mu PTFE kukonza ndi zigzag mawonekedwe, chifukwa fluorine atomu utali wozungulira wamkulu kuposa haidrojeni, kotero moyandikana CF2 mayunitsi sangathe kuwoloka ndendende trans orientation, koma kupanga kozungulira zopotoka unyolo, fulorini atomu kuphimba pafupifupi lonse polima unyolo pamwamba.Maselo a maselowa amafotokoza zinthu zosiyanasiyana za PTFE.Pa kutentha pansi pa 19 ℃ kupanga 13/6 helix;Kusintha kwa gawo pa 19 ℃, kumasula pang'ono mamolekyu kuti apange 15/7 helix.
Ngakhale ma perfluorocarbon carbon - carbon bond ndi carbon - fluorine bond amasweka akufunika kuyamwa mphamvu 346.94 ndi 484.88kJ/mol, koma PTFE depolymerization mphamvu imapanga 1mol tetrafluoroethylene imangofunika 171.38kJ.Choncho mu pyrolysis, PTFE makamaka depolymerizate tetrafluoroethylene.PTFE pa 260,370 ndi 420 ℃ chiwerengero cha kuwonda (%) chinali 1 × 10-4, 4 × 10-3 ndi 9 × 10-2 pa ola limodzi.
