O le a le PTFE?
Polytetrafluoroethylene (PTFE) o se ituaiga polymer polymerized ma tetrafluoroethylene pei monomer.E sili ona lelei le vevela ma le malulu ma e mafai ona faʻaaogaina mo se taimi umi i lalo ifo o le 180 ~ 260 º C. O lenei mea o loʻo i ai uiga o le acid resistance, alkali resistance ma le tetee atu i solvents organic eseese, ma e toetoe lava a le mafai ona faʻaaogaina i solvents uma.I le taimi lava e tasi, o le polytetrafluoroethylene o loʻo i ai uiga o le maualuga o le vevela, ma o lona faʻalavelave faʻafefe e matua maualalo lava, o lea e mafai ai ona faʻaaogaina mo le lubrication, ma avea foi ma se ufiufi lelei mo le faʻamamaina faigofie o le pito i totonu o paipa vai.PTFE e faasino i le faʻaopoopoga o le ufiufi ufiufi PTFE i totonu o le paʻu paʻu masani EPDM, lea e masani ona paʻepaʻe.
Le matafaioi a le PTFE
E mafai e le PTFE ona puipuia lelei so'oga pa'u mai le malosi malosi, malosi alkali po'o le suau'u vevela maualuga ma isi fa'asalalauga.
Faamoemoega
- E faʻaaogaina i le eletise eletise ma e pei o le insulation layer, mea e faʻafefeteina ma faʻaofuofu mea mo le malosi ma laina faʻailoga i le aerospace, vaalele, eletise, meafaigaluega, komepiuta ma isi pisinisi.E mafai ona faʻaaogaina e fai ai ata tifaga, faʻamau pepa, tootoo, bearings, gaskets, valves, paipa vailaʻau, paipa faʻapipiʻi, mea faʻapipiʻi pusa, ma isi.
- E faʻaaogaina i le fanua o mea eletise, vailaʻau vailaʻau, vaalele, masini ma isi fanua e sui ai tioata quartz mo le suʻesuʻeina o vailaʻau ultra-mama ma le teuina o vailaʻau eseese, alkalis ma solvents organic i fanua o le malosi atomic, vailaʻau, semiconductor. ma isi alamanuia.E mafai ona faia i totonu o vaega eletise insulation maualuga, uaea tele ma uaea sheaths, corrosion resistant utensils utensils, maualuga vevela tetee suauu paipa, totoga faafoliga, ma isi. ga'o, ma isi.
- PTFE e tetee atu i le maualuga o le vevela ma le pala, e sili ona lelei le faʻaogaina o le eletise, matua teteʻe, maualalo le faʻaogaina o le vai, ma le lelei tele o le lubrication.O se paʻu lubricating lautele talafeagai mo ala o faasalalauga eseese, ma e mafai ona vave ufiufi e fai ai se ata mago, lea e mafai ona faaaoga e fai ma sui mo graphite, molybdenum ma isi lubricants inorganic.O se sui faʻamalolo e talafeagai mo polymers thermoplastic ma thermosetting, faʻatasi ai ma le gafatia lelei.E faʻaaogaina lautele i le elastomer ma le paʻu alamanuia ma i le puipuia o le pala.
- I le avea ai o se faʻatumu mo le epoxy resin, e mafai ona faʻaleleia le faʻafefeteina o le abrasion, teteʻe o le vevela ma le faʻafefe o le epoxy adhesive.
- E masani ona faʻaaogaina e fai ma fusi ma faʻatumu o le paʻu.
Tulaga lelei o le PTFE
- Tete'e maualuga o le vevela - vevela galue e oo atu i le 250 ℃
- Tete'e maualalo o le vevela - malosi fa'ainisinia lelei;E tusa lava pe pa'ū le vevela ile -196 ℃, e mafai ona faʻatumauina le faʻalauteleina ole 5%.
- Tete'e o le pala - mo le tele o vaila'au ma solvents, e le mafai ma e tete'e i acids malolosi ma alkalis, vai ma so'o so'o eseese.
- Tete'e tau - e sili ona lelei le soifua matua o palasitika.
- O le lubrication maualuga o le pito sili ona maualalo o le fe'avea'i fa'atasi i mea malō.
- Le faʻapipiʻi - o le faʻamaualalo pito i luga ole vaʻaia i mea mautu ma e le pipii i soʻo se mea.
- E le o'ona - E i ai le physiological inertia, ma e leai ni fa'alavelave fa'aletonu pe a uma ona fa'atumauina mo se taimi umi e fai ma toto toto ma totoga.
- Insulation eletise - e mafai ona tatalia 1500 V maualuga voltage.
