Mochini oa Theipi oa PTFE polymer

Re ikakhetse ka setotsoana mochini oa theipi oa PTFE polymer, oo hape o bitsoang mochini oa theipi oa PTFE, mochini oa theipi oa Thread seal, lilemo tse fetang 20, joale o hlompha ISO9001 le setifikeiti sa CE se fumanoeng.Ke rona ba pele ba etsang Mochini oa Theipi oa PTFE China.Hase feela hore re ka u fa mohala oa tlhahiso, empa hape re fana ka thepa e tala.Mechini e meholo e kenyelletsa: Mixer, Calender, Slitter, Pressing Machine, Oven, Wrapping Machine joalo-joalo.

Mefuta e fapaneng ea theipi ea ho qetela ea PTFE:Botenya: 0.05-0.3mm kapa ho feta (ho ea ka tlhoko ea hau);Bophara: 8mm, 10mm, 12mm, 19mm, 25mm kapa tse ling, ho ea ka tlhokahalo ea hau;Bolelele: 8m, 10m, 12m, 15m, 18m, 20m ,25m, 40, joalo-joalo..ho latela tlhoko ea hau.

PTFE e sebelisoa haholo litlhoko tse fapaneng, joalo ka: li-anti-acid le li-organic solvents, tseo ka botsona tse se nang chefo ho batho, empa e 'ngoe ea lisebelisoa tse sebelisoang molemong oa tlhahiso ea ammonium perfluorooctanoate (PFOA) e nkoa e ka ba le eona. phello ea carcinogenic.

E kholo e amanang le molek'hule ea PTFE, e ka tlaase e le makholo a likete, ha e phahameng e ka fihla ho milione kapa ho feta (tekanyo ea polymerization ea litaelo tsa 104 tsa boholo, ha polyethylene e le 103 feela).Tekanyo ea crystallinity ka kakaretso ke 90 ho 95%, mocheso o qhibilihang oa 327 ~ 342 ℃.Molek'hule CF2 yuniti ka PTFE lokisetsa ka sebopeho zigzag, hobane fluorine athomo radius kholoanyane ho feta hydrogen, kahoo, haufi CF2 diyuniti ke ke tšela hantle trans orientation, empa theha spiral sothehileng ketane, fluorine athomo koahela hoo e ka bang eohle polymer ketane bokaholimo.Sebopeho sena sa limolek'hule se hlalosa mefuta e sa tšoaneng ea PTFE.Ka mocheso o ka tlase ho 19 ℃ ho theha 13/6 helix;Phato ea phetoho ho 19 ℃, e manolla molek'hule ho etsa 15/7 helix.

Leha perfluorocarbon carbon - carbon bond le carbon - fluorine bond li robehile tlhokahalo ea ho monya matla 346.94 le 484.88kJ/mol, empa PTFE depolymerization energy e hlahisa 1mol tetrafluoroethylene e hloka 171.38kJ feela.Kahoo ho pyrolysis, PTFE haholo-holo depolymerizate tetrafluoroethylene.PTFE ho 260,370 le 420 ℃ sekhahla sa tahlehelo ea boima ba 'mele (%) e ne e le 1 × 10-4, 4 × 10-3 le 9 × 10-2 ka hora.
