Ts'ebetso ea tlhahiso eaPhaephe ea PTFEke: PTFE, thuso ea ho ntša metsi → ho kopanya → ho tobetsa → ho omisa → ho sila → ho pholisa → sehlahisoa
Ts'ebetso ea ho bopa lipeipi tsa PTFE e kenyelletsa mokhoa oa ho sututsa, mokhoa oa ho ntša metsi, mokhoa oa hydraulic, mokhoa oa ho tjheseletsa, mokhoa oa ho kobeha, jj., eo har'a eona mokhoa oa ho sututsa e leng mokhoa o ka sehloohong. Ka kakaretso, ho sebelisoa resin ea PTFE e hasantsoeng e nang le boholo ba likaroloana tsa 500μm le boima bo bonahalang ba 0.45gml ~ 0.55gml. Bakeng sa lipeipi tse nyane tsa bophara, sebelisa resin e nang le khatello e kholo, 'me bakeng sa lipeipi tse kholo tsa bophara, sebelisa resin e nang le khatello e nyane. Sesebelisoa sa ho hatella hangata se khetha linoko tsa 200 le 260 tsa diminerale. Ts'ebetso ea bobeli ea lipeipi tsa PTFE e ka hlahisa lipeipi tse fokotsang mocheso tsa PTFE, lipeipi tsa spiral tsa PTFE, lipeipi tsa hydraulic tsa PTFE, jj.
Tube ea polytetrafluoroethylene e entsoe ka resin e hasantsoeng ea polytetrafluoroethylene mochesong oa kamore ho sebelisoa solvent ea organic e le thuso ea extrusion, ebe e omisoa le ho siloa. Ho ea ka bophara ba tube, e ka aroloa ka mefuta e 'meli: tube e tloaelehileng le tube e nyenyane. Bophara ba ka hare ba tube e tloaelehileng ke 4mm, 'me bophara ba ka hare ba tube e nyenyane bo ka tlase ho kapa bo lekana le 4mm.
Ts'ebetso ea tlhahiso ea tube ea PTFE ke: PTFE, thuso ea extrusion → ho kopanya → ho tobetsa → ho omisa → ho sintering → ho pholisa → sehlahisoa.
Liphaephe tsa polytetrafluoroethylene li na le matla a matle a mechini. Liphaephe tsena ke liphaephe tse bataletseng, liphaephe tse bōpehileng joaloka V, masale a piston, liphaephe tsa valve ea bolo, jj., tse entsoeng ka lithupa tsa PTFE, liphaephe le lipoleiti ka ho reteleha kapa ho seha ka mechini, tse hanelang mafome, tse hanyetsang le tse sa tsamaiseng motlakase.
1. Lipeipi tsa Teflon ka kakaretso li sebelisa mokhoa oa ho etsa li-compression, 'me ho etsa li-plunger extrusion ho ka sebelisoa. Resin e fumanoeng ka mokhoa oa ho hasanya polymerization e ka etsoa ka ho etsa li-paste extrusion le calendering.
2. PTFE e na le boleng ba pH ba 0-14 (ntle le litšepe tsa alkali tse qhibilihisitsoeng le fluorine tlas'a mocheso o phahameng le khatello e phahameng), tse ka bang le matla a matle a mechini pakeng tsa 100°C le 100°C.
3. Maemo a itseng a tshebetso ke hore kgatello ya pele e fapana ho ya ka sebopeho le boholo ba sehlahiswa. Empa hangata e sebediswa. Sephutheloana se lohiloeng ka Teflon ke 8-34.3MPa, mme resin e nang le setlatsetso ke 29.4-93MPa. Bakeng sa boya bo boholo bo nang le botenya ba hoo e ka bang 600mm ka lehlakoreng la ho hatella, ho ntse ho na le nako ya ho tshwara kgatello ya metsotso e 20-30. Hlokomela hore ha mocheso o le tlase ho 185°C. Tube ya Teflon e tla tetebela. Gasket e hlwekileng ya PTFE ke sehlahiswa se hlwekileng sa ho kwala se ke keng sa silafatsa ntho efe kapa efe eo se kopanang le yona mme se ka sebediswa haholo dijong, merianeng le diindastering tse ding.
