Boima ba lesela la fiberglass bo lekanya hore PTFE e sebetsa ka mocheso o phahameng oa mocheso. Boima bo phahameng bo eketsa matla a tsitsipano le boreleli bo holim'a metsi empa bo fokotsa matla a ho taboha (inverted U-curve), ho tenyetseha, le ho kenella ka hare. Tekano e nepahetseng e leka-lekanya ho kenella, ho hanyetsa meokho, ho tenyetseha le ho fella ka holimo. Boima bo tlase bo lumellana le ho kobeha ho matla; boima bo boholo bakeng sa ho se thunye le ho kenya letsoho.

Calendering - ho hatella lesela le koahetsoeng ke PTFE pakeng tsa lirolara tsa seipone tse futhumetseng ka 360-380 ° C - ho fetola ka mokhoa o makatsang sebopeho sa bokaholimo, thepa ea ho lokolla, ho se khonehe, le ts'ebetso ea mochini. E fokotsa boima ho tloha ho Ra 0.5-1.0 μm ho <0.05 μm, e tiisa li-pinholes, e ntlafatsa ho hanyetsa ho apara, empa e fokotsa matla a ho taboha le ho feto-fetoha ha maemo. E bohlokoa bakeng sa li-liner tse lokollang le ho kenya motlakase.

Fiberglass weave pattern - plain, twill, kapa satin - e ama haholo PTFE thepa ea lesela la mocheso o phahameng oa mocheso. Satin weave e fana ka matla a phahameng a ho tabola (2-3x thota) le ho tenyetseha, e loketseng ho kobeha ho matla. Plain weave e fana ka botsitso bo botle ka ho fetesisa le ho khomarela lekhapetla, e loketseng lits'ebetso tse tsitsitseng. Twill e leka-lekanya thepa eohle bakeng sa tšebeliso e akaretsang.

Ho roala ho tšoana ha lesela la PTFE mocheso o phahameng ho khethoa ke lintlha tse 'nè: sebopeho sa ho roala (saese ea boholo ba 0.15-0.35 μm, viscosity, dikahare tse tiileng), mokhoa oa ho roala le oa sintering (ho roala ka lehare ho khethoa bakeng sa ho lumellana), boleng ba substrate (paterone ea weave, pele ho phekolo), le tikoloho ea tlhahiso (20-25% R <60%). Dip + blade e kopantseng ts'ebetso e leka-lekanya ho kenella le ho boreleli holimo.

Ho hloekisa le tlhokomelo e nepahetseng ho lelefatsa bophelo ba lesela la mocheso o phahameng oa PTFE. Hloekisa ka mor'a ho sebelisoa le ka mor'a ho pholile. Sebelisa borashe bo bonolo, li-detergents tse sa jeleng paate, kapa joala bakeng sa litšila. Le ka mohla u se ke ua sebelisa li-acid tse matla/alkalis, bleach, kapa metal scrapers. Ho tlotsa oli ea silicone khafetsa ho fokotsa ho roala. Latela litataiso tsena ho thibela tšenyo ea lira.

PTFE lesela la mocheso o phahameng oa mocheso le lesela la silicone ka bobeli li sebelisa lesela la fiberglass e le motheo empa li fapane ka thepa ea ho roala (PTFE resin vs silicone rabara). PTFE e ipabola tabeng ya ho se thure, ho se mamelle, le ho hanyetsa dikhemikhale ho fihla ho 260°C. Lesela la silicone le fana ka maemo a holimo, ho kenya motlakase, le ho hanyetsa mollo (ho fihlela ho 230 ° C). Khetha ho latela lintho tse tlang pele bophelong ba hau.

PTFE lesela la mocheso o phahameng oa mocheso (PTFE membrane material) ke khetho ea pele bakeng sa meralo e tsitsitseng. Melemo ea bohlokoa: lilemo tse 30+ tsa bophelo ba kantle, sebaka sa ho itlhoekisa (metsi a pula a hlatsoa litšila), phetiso ea mabone a bonolo (6-13%), boemo ba mollo oa Sehlopha sa A, le matla a kang tšepe a ka tlase ho 1.5 kg/m². E sebelisoa mabaleng a lipapali, boema-fofane le meaho e ikhethang lefatšeng ka bophara.

Lesela la PTFE la mocheso o phahameng le fana ka khanyetso e ikhethang ea lik'hemik'hale, le mamella li-acid tse matla, alkalis, solvents organic, le likhase tse senyang. Sengoliloeng sena se qaqisa lintho tsa sona tse hanyetsanang, mefokolo (metaele ea alkali e qhibilihisitsoeng, lisebelisoa tse matla tsa fluorinating), le lintlha tsa bohlokoa joalo ka mocheso, khatello ea maikutlo le khatello ea maikutlo.

PTFE impregnation ha e felle feela ho fiberglass lesela. Sengoliloeng sena se hlahisa li-substrates tse 7 tse ling - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (phased out), le li-filler tsa ceramic - ka likarolo tsa bona tsa ts'ebetso, melemo, mefokolo, le lits'ebetso tsa bohlokoa.

Lesela le phefumolohang haholo la PTFE le nang le mocheso o phahameng oa mocheso le kopanya thepa e se nang thupa, botsitso ba mocheso, le ho kenella ha moea. Sengoliloeng sena se hlahloba lits'ebetso tsa sona tsa bohlokoa ho omiseng masela, ho lokisa lijo, ho etsa lihlahisoa tse kopaneng, lisebelisoa tsa elektroniki, phepelo ea moea, ts'ireletso ea tikoloho le thepa ea kaho.
