Yedu inobatikana mukugadzira PTFE polymer tepi muchina, iyo inonziwo PTFE tepi muchina, Thread seal tepi muchina, anopfuura makore makumi maviri, ikozvino kukudza ISO9001 uye CE chitupa chakawanikwa.Isu tiri vekutanga kugadzira PTFE Tape Machine muChina.Kwete chete isu taigona kukupa iwe mutsara wekugadzira, asi zvakare kupa mbishi zvinhu.Michina mikuru inosanganisira: Mixer, Calender, Slitter, Pressing Machine, Oveni, Kupeta muchina nezvimwe.
Range yekupedzisira PTFE thread seal tepi:Ukobvu: 0.05-0.3mm kana kupfuura (maererano nezvaunoda);Upamhi: 8mm, 10mm, 12mm, 19mm, 25mm kana vamwe, maererano nezvaunoda;Kureba: 8m, 10m, 12m, 15m, 18m, 20m ,25m, 40, nezvimwewo..maererano nezvaunoda.
PTFE inoshandiswa zvakanyanya mune zvakasiyana-siyana zvinodiwa, se: anti-acid uye organic solvents, iyo pachayo isina chepfu kuvanhu, asi imwe yemidziyo inoshandiswa mukugadzirwa kweammonium perfluorooctanoate (PFOA) inoonekwa seine a carcinogenic effect.
Hombe hama molecular yePTFE, iyo yakaderera semazana ezviuru, nepo yakakwirira imwe inogona kusvika miriyoni imwe kana kupfuura (dhigirii repolymerization ye104 mirairo yehukuru, nepo polyethylene chete 103).Dhigirii yecrystallinity inowanzoita 90 kusvika 95%, tembiricha yekunyunguduka ye327 ~ 342 ℃.Molecule CF2 unit muPTFE inoronga nechimiro chezigzag, nekuti fluorine atomu radius yakakura kupfuura haidhirojeni, saka mayunitsi eCF2 ari padhuze haakwanise kuyambuka chaizvo, asi kugadzira cheni yakamonyoroka, atomu yefluorine inovhara inenge yese polymer cheni.Ichi chimiro che molecular chinotsanangura zvakasiyana siyana zvePTFE.Pakupisa kuri pasi pe19 ℃ kuita 13/6 helix;phase shanduko pa19 ℃, vhura zvishoma molecule kuita 15/7 helix.
Kunyangwe iyo perfluorocarbon kabhoni - kabhoni bond uye kabhoni - fluorine zvisungo zvakaputswa zvinoda kutora simba 346.94 uye 484.88kJ/mol, asi PTFE depolymerization simba rinogadzira 1mol tetrafluoroethylene inongoda 171.38kJ.Saka mu pyrolysis, PTFE inonyanya depolymerizate tetrafluoroethylene.PTFE pa260,370 uye 420 ℃ chiyero chekurasikirwa (%) chaive 1 × 10-4, 4 × 10-3 uye 9 × 10-2 paawa.
