Liphetoho ho Corrosion Resistance of PTFE High Temperature Cloth in Faffering Chemical Media (Strong Oxidants, Organic Solvents, jj.)

E tlisoa ho uena ke Jiangsu Aokai New Materials, setsebi sa moetsi oa PTFE mocheso o phahameng oa lesela.PTFE lesela la mocheso o phahameng le tsebahala ka botsitso bo ikhethang ba lik'hemik'hale, bo tsoang ho sebopeho se matla sa limolek'hule tsa thepa ea eona ea mantlha - Polytetrafluoroethylene (PTFE). Ha e pepesehetse mecha ea litaba e fapaneng ea lik'hemik'hale, khanyetso ea eona ea kutu e lula e tsitsitse ka kakaretso, ka maemo a 'maloa feela a ikhethang a hlokang tlhokomelo e khethehileng. Sengoliloeng sena se qaqisa liphetoho tsa eona tsa ts'ebetso maemong a fapaneng a lits'ebeletso.

1. Li-Oxidants tse Matla: Lesela la PTFE Mocheso o Phahameng le lula le sa sebetse ka lik'hemik'hale

Libakeng tse matla tsa oxidizing, khanyetso ea kutu ea lesela la mocheso o phahameng oa PTFE ha e fetohe. E hanela khoholeho ea mobu ho tsoa ho mefuta e mengata ea li-oxidants tse matla, ho kenyelletsa potassium permanganate, hydrogen peroxide, hypochlorite ea sodium le potassium dichromate.Ho rua molemo ho sebopeho sa eona se tsitsitseng haholo sa limolek'hule, lesela ha le hlahise lik'hemik'hale tsa lik'hemik'hale, ho ruruha kapa ho senyeha ha li kopana le li-oxidants tse ka holimo. Ka hona, ha e sebelisoa lits'ebetsong tse matla tsa lik'hemik'hale tsa oxidation, matla a eona a 'mele le thepa ea bokaholimo li bolokiloe hantle, li fana ka ts'epo e ntle ea ts'ebeletso ea nako e telele.

2. Li-solvents tsa Organic: Ts'ebetso e Felletseng ea Resistance

Ha u qoelisoa ka har'a metsoako ea lintho tse hlapollang, PTFE lesela la mocheso o phahameng le boloka ho hanyetsa ha kutu ho tsitsitseng ka ho feletseng. E na le ho se sebetse ho feteletseng ha lik'hemik'hale khahlanong le joala (ethanol), li-ketone (acetone), li-hydrocarbon tse nkhang hamonate (toluene, xylene), li-halogenated hydrocarbons, peterole, mafura le liphahlo tse fapaneng tsa resin.

Lintlha tsa liteko li bontša hore le ho 300 ℃, ke li-alkane tse 'maloa feela tse nang le perfluorinated tse bakang ho qhibiliha ho fokolang. Mocheso oa kamore, lesela la mocheso o phahameng oa PTFE le ke ke la qhaqhoa kapa la ruruha leha e le efe e tsejoang e le motsoako oa lintho tse phelang.

3. Li-Acids, Alkalis le Matsoai: Boemo bo Feletseng bo Felletseng

Ho phaella mecheng ea litaba e ka holimo, lesela la mocheso o phahameng oa PTFE le bontša liphetoho tse sa tsotelleng tsa ts'ebetso ho acid e matla, alkali e matla le libaka tse phahameng tsa letsoai.

E mamella ho qoelisoa ka nako e telele ho sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid esita le aqua regia. Ha ho tahlehelo e hlakileng ea boima ba 'mele kapa ho fokotseha ha ts'ebetso ea mochini ho etsahalang, esita le ho belisa li-acid tse matla. E boetse e hanela ho qhibiliha le ho senyeha ha matla ha e pepesehetse mocheso o phahameng oa alkalis joalo ka sodium hydroxide le ammonia. Sebakeng se senyang ho kenyelletsa metsi a leoatle, brine, khase ea chlorine le sulfur dioxide, e lula e na le litšobotsi tsa eona tsa pele tse se nang thupa, tse hanyetsanang le boemo ba leholimo le litšupiso tsa motlakase.

4. Mekhelo e Khethehileng: Maemo a Feteletseng a Mosebetsi a Lokela ho Qojoa

Le hoja lesela la mocheso o phahameng oa PTFE le na le matla a mangata a ho hanyetsa kutu, palo e nyenyane ea lik'hemik'hale tse khethehileng e tla thibela ts'ebetso ea eona ea tšireletso.

Ntlha ea pele, ho kopana le tšepe ea alkali e qhibilihisitsoeng (e kang sodium le potasiamo) ho tlameha ho qojoa, kaha lintho tsena li tla senya sebopeho sa eona sa molek'hule.Ya bobeli, mahlahana a khethehileng a matla a fluorinating (elemental fluorine, chlorine trifluoride) e tla baka khoholeho ea mobu, haholo-holo tlas'a mocheso o phahameng le maemo a moferefere.

Mocheso e boetse ke moeli oa bohlokoa: ha mocheso oa tikoloho o feta 400 ℃, PTFE e qala ho bola 'me e ntša khase e chefo, e leng se bakang tahlehelo ea hang-hang ea ho hanyetsa ho bola le matla a mochine.

Kakaretso

Mecha ea phatlalatso ea lik'hemik'hale tse ngata tsa indasteri, lesela la mocheso o phahameng oa PTFE le boloka ts'ebetso e fokolang ea ts'ebetso. Mamello ea eona e phahameng e etsa hore e be thepa e loketseng ho thibela kutu, ho tiisa le ho lokolla . Hafeela ho kopana le tšepe ea alkali e qhibilihisitsoeng le mocheso o phahameng haholo oa ho bola ho qojoa, ho hanyetsa ha eona ho matla haholo ho ka sebelisoa ka botlalo, ho boloka boemo ba eona bo ke keng ba nkeloa sebaka maemong a thata a ts'ebetso ea lik'hemik'hale

Litaba tsena li fanoe ke Jiangsu Aokai New Material Technology Co., Ltd.

Re fana ka lihlahisoa tse fapaneng: lesela la mocheso o phahameng oa PTFE, tepi ea mocheso o phahameng oa PTFE, lebanta la mocheso o phahameng oa PTFE, lebanta la mochine o se nang seamless, lesela le nang le mahlakoreng a mabeli a PTFE, lebanta le nang le mocheso o phahameng oa mocheso le lesela la fiberglass le mocheso o phahameng.
