Lesela la PTFE la Mocheso o Phahameng oa Mocheso o Hakae?

Limeleng tsa lik'hemik'hale, lithapo tsa electroplating, le masela a semiconductor, lisebelisoa li lula li pepesetsoa acid e mabifi, alkalis le solvents. Ho khetha thepa e nepahetseng ea tšireletso ho ama ka ho toba polokeho le bophelo ba lisebelisoa.

PTFE (polytetrafluoroethylene) hangata e bitsoa 'morena oa polasetiki' ka lebaka la ho se sebetse ho feteletseng ha lik'hemik'hale. Empa 'inert' ha e bolele 'e sa hlōloeng' - ke lik'hemik'hale life tse ka e senyang? Mocheso le ho tsepamisa mohopolo li ama tšebetso ea eona joang?

Ho Aokai PTFE , re qetile lilemo tse ngata re etsa liteko Masela a koahetsoeng ke PTFE khahlano le tikoloho ea lefatše ea 'nete ea lik'hemik'hale. Sengoliloeng sena se arolelana seo re se fumaneng ho u thusa ho khetha ka bohlale.

Lik'hemik'hale Tse PTFE Lesela le Phahameng la Mocheso le Hanyetsang

1. Li-Acids tse Matla

Lesela la PTFE le fana ka khanyetso e ntle ho:

• Asiti ea sulfuric (H₂SO₄)

• Asiti ea nitric (HNO₃)

• Hydrochloric acid (HCl)

• Phosphoric acid (H₃PO₄)

• Li-acid tse ngata tse nang le oxidizing joalo ka aqua regia le hydrofluoric acid (HF)

2. Li-Alkali tse Matla

E hanyetsana le sodium hydroxide (NaOH), potassium hydroxide (KOH), ammonia water (NH₃·H₂O), le lintho tse ling tse matla tsa alkaline.

3. Litlhapi tsa Organic

Ho kenella ka lik'hemik'hale khahlano le metsoako e mengata ea tlhaho, ho kenyelletsa le joala (methanol, ethanol), ketone (acetone, MEK), li-hydrocarbon tse nkhang hamonate (benzene, toluene, xylene), le peterole.

4. Lik'hemik'hale Tse Ling

E boloka ts'ebetso e tsitsitseng khahlanong le li-oxidants (mohlala, hydrogen peroxide), matsoai (sodium chloride, sodium sulfate), le likhase tse senyang (chlorine, hydrogen sulfide).

Meeli - Lik'hemik'hale Tse Senyang Lesela la PTFE

Ho sa tsotellehe khanyetso e phahameng ea lik'hemik'hale, lesela la mocheso o phahameng oa PTFE le na le mefokolo tlas'a maemo a phahameng a mocheso kapa a mangata. Lik'hemik'hale tse 'maloa tse ikhethileng li ka baka tšenyo joalo ka ha li thathamisitsoe ka tlase:

Ho feta moo, lesela le koahetsoeng la PTFE ha le khothalletsoe ho sebelisoa le:

• Chlorine trifluoride (ClF₃) - ho chesa ka tšohanyetso ho ka etsahala

• Oxygen difluoride (OF₂) - karabelo e mabifi

• Fluorine ea metsi kapa ea gaseous (F₂) mochesong o phahameng - e hlasela PTFE

Lintlha tse Amang Khahlano ea Lik'hemik'hale ea Lesela le Koaetsoeng la PTFE

Lintlha tse 'maloa li ama khanyetso ea 'nete ea kutu ea lesela la mocheso o phahameng oa PTFE lits'ebetsong tsa lefats'e la nnete:

• Mocheso: Ts'ebetso e tsitsitseng ea lik'hemik'hale e bolokiloe ka har'a -70°C ho isa ho 260°C. Khanyetso e ea fokotseha khahlanong le lik'hemik'hale tse itseng mochesong o phahameng haholo.

• Maikutlo: Ho qoelisoa ka nako e telele mecheng ea litaba e senyang haholo ho ka senya ts'ebetso ea thepa. Teko sebakeng se khothaletsoa.

• Khatello ea kelello ea mochine: Ho bola ha lik'hemik'hale tse kopantsoeng le likhohlano tsa mechine li potlakisa botsofali. Ho sireletsa lesela la PTFE ho tloha mengopeng ho bohlokoa - hang ha e senyehile, khalase ea fiberglass e ka ba kotsing.

• Nako ea ho pepeseha: Ho hana ho phatloha ha nakoana ho fapana le ho qoelisoa ho sa khaotseng.

• Khatello: Khatello e phahameng e ka qobella lik'hemik'hale hore li kene ka har'a li-pores tse nyenyane haholo kapa likoli tse koahelang.

Lintlha tsa lab tsa Aokai PTFE li bonts'a hore likamano tsa mocheso le mocheso hangata ha li nyenyefatsoe. Ka mohlala, lesela la PTFE le nkang lilemo tse 50% sulfuric acid ho 100 ° C le ka 'na la bontša ho soeufala ha metsi ka mor'a likhoeli tse 200 ° C le mahloriso a tšoanang. Kamehla sebelisa moeli oa polokeho.

Kakaretso - Khanyetso ea Lik'hemik'hale ea Lesela la PTFE High-Mocheso

Bakeng sa libaka tse ngata tsa lik'hemik'hale tsa indasteri, lesela le koahetsoeng la PTFE le fana ka ts'ebetso e tšepahalang, e tšoarellang nako e telele. Leha ho le joalo, kamehla netefatsa ho lumellana tlas'a maemo a sebele a ts'ebetso - haholo-holo mocheso, mahloriso le khatello ea mochine.

Ka bokhutšoanyane , lesela la PTFE la mocheso o phahameng le fana ka khanyetso e ikhethang ho hoo e batlang e le li-acids tsohle, li-alkali, le li-solvents tsa organic ka har'a mefuta e tloaelehileng ea ho sebetsa (-70 ° C ho isa ho 260 ° C). Mekhelo ea bohlokoa ke tšepe ea alkali e qhibilihisitsoeng le lisebelisoa tse matla tsa fluorinating. Li-acid tse chesang, tse teteaneng tsa oxidizing le tsona li hloka tlhokomeliso e eketsehileng.

Ha e le hantle, mocheso, khatello ea kelello le khatello ea kelello li sebetsa hammoho ho ama bophelo ba lintho tse bonahalang. Bakeng sa maemo a mahlonoko, re khothaletsa tlhahlobo ea setšeng kapa ho sebelisa moeli oa polokeho oa 30-40 ° C ka tlase ho mocheso o lekantsoeng haholo.
