Khatello e phahameng ea teflon hose e ka mamella mocheso o phahameng?

The high-pressure teflon Hose e ka mamella mocheso o phahameng, ke likhato tse kae, haholo-holo ho itšetlehile ka litšobotsi tsa eona tse khethehileng tsa thepa, botenya, tšebeliso ea tikoloho le phekolo e ka khonehang holim'a metsi le lintlha tse ling.

Mefuta e phahameng ea mocheso e hanyetsanang le mocheso

1. Kakaretso ea kakaretso:

Ka tloaelo, hose ea teflon e nang le khatello e phahameng e ka mamella mocheso o tsitsitseng o ka bang likhato tse 260.

Tlas'a boemo ba mocheso o phahameng hang-hang, mocheso oa eona oa mamello o ka fihla likhato tse 400.

2. Maemo a khethehileng

Maemong a mang a khethehileng, joalo ka khatello e tlase le phallo e tlase ea khase, ho hanyetsa mocheso oa teflon hose ho ka ba holimo, esita le ho fihlela ho 300 ° C.

Litšobotsi tsa lintho tse bonahalang

Li-hose tsa teflon tse nang le khatello e phahameng li entsoe haholo-holo ka lisebelisoa tsa polytetrafluoroethylene (PTFE), tse nang le mocheso o motle haholo. PTFE e tsitsitse ka lik'hemik'hale, e khona ho mamella li-acids tsohle tse matla (ho akarelletsa le aqua regia) , li-oxidants tse matla, li-reduction agents le li-solvents tse fapa-fapaneng ntle le tšepe ea alkali e qhibilihisitsoeng, mecha ea litaba ea fluorinated le sodium hydroxide ka holimo ho 300 ° C. Hose ea teflon e phahameng ea khatello e phahameng e boetse e na le litšobotsi tsa eona. ea ho hanyetsa ho roala le ho itšehla thajana, coefficient e tlase ea likhohlano, e etsang hore e be maemong a fapaneng a rarahaneng a ka bolokang boemo bo tsitsitseng ba ho sebetsa.

Maemo a kopo

Hose ea teflon e nang le khatello e phahameng e sebelisoa haholo indastering ea lik'hemik'hale, k'hemisteng, ho lokisa lijo le liindasteri tse ling ka lebaka la mocheso oa eona o phahameng haholo, mocheso o tlase le khanyetso ea ho bola ha lik'hemik'hale. Ka indasteri ea lik'hemik'hale, e ka tsamaisa mefuta eohle ea lik'hemik'hale ka katleho; indastering ea meriana, e ka netefatsa tikoloho ea lipalangoang e hloekileng le e hloekileng; tšimong ea ho lokisa lijo, e ka boela ea tiisa tšireletso ea lijo le bohloeki.

Lintlha tseo u lokelang ho li ela hloko

1. Ho atolosoa ha mocheso le ho fokotseha: le hoja hose ea teflon e nang le khatello e phahameng e ka mamella mocheso o tlase ho ea ho -190 likhato, empa ho sebelisoa ha mocheso o tlaase ka ho fetisisa, ho hlokahala hore ho nahane ka ho atolosoa ha mocheso le ho fokotseha ha ts'ebetso ea hose. Ka kakaretso, moeli o bolokehileng le o sebetsang oa mocheso o khothalletsoang ho pota -70 degrees.

2. Moeli oa khatello: ntle le mocheso o phahameng oa ho hanyetsa, hose ea teflon e nang le khatello e phahameng e ka boela ea mamella khatello e phahameng (e kang hoo e ka bang 100 bar) , empa ka mekhoa e sebetsang e hloka ho khetha litlhaloso tse nepahetseng tsa hose le mehlala ho ea ka maemo a itseng.

Hose e phahameng ea khatello ea teflon tlas'a maemo a tloaelehileng ho mamella mocheso o phahameng o tsoelang pele oa likhato tse ka bang 260, mocheso o phahameng oa hang-hang o ka fihla likhato tse 400. Tlas'a maemo a itseng, ho hanyetsa mocheso oa eona ho ka 'na ha e-ba holimo. Leha ho le joalo, ha ho sebelisoa tlhokahalo ea ho ela hloko ho atolosoa ha mocheso le ho fokotseha ha tšusumetso ea likhatello tsa khatello le lintlha tse ling.
