PTFE plate e na le khanyetso e ntle ka ho fetisisa ea abrasion har'a lipolasetiki tsohle tsa boenjiniere 'me ke eona e hapang mahlo ka ho fetisisa.Ha boima ba molek'hule bo phahame, ke moo thepa e sa senyeheng, ho feta lisebelisoa tse ngata tsa tšepe (tse kang carbon steel, stainless steel, bronze, joalo-joalo).Ka mohlala, liphaephe tsa UHMW-pe li na le bophelo ba tšebeletso ea makhetlo a 4-6 ho feta liphaephe tsa tšepe tlas'a maemo a ho senyeha ho matla le ho apara holimo, 'me katleho ea phetisetso e eketseha ka 20%.E bontša ka botlalo bophahamo ba "poloko ea matla, ts'ireletso ea tikoloho, moruo, le ts'ebetso e phahameng".
Melemo ea poleiti ea PTFE ke efe?
Ho hanyetsa mocheso o phahameng- Mocheso o sebetsang o ka fihla ho 250 ℃.
Ho hanyetsa mocheso o tlase- E na le matla a matle a mochini;leha thempereichara e theohela ho -196℃, e ka boloka bolelele ba 5%.
Khanyetso ea kutu- Ha e na matla ho lik'hemik'hale tse ngata le li-solvents, 'me e khona ho mamella li-acids tse matla le alkalis, metsi le li-solvents tse fapaneng tsa tlhaho.
Ho hanyetsa boemo ba leholimo- E na le bophelo bo botle ba botsofali har'a polasetiki.
Lubrication e phahameng- Coefficient e tlase ea likhohlano lipakeng tsa lisebelisoa tse tiileng.
Ho se khomarele- Ke tsitsipano e nyane ka ho fetisisa ea holim'a metsi har'a lisebelisoa tse tiileng 'me ha e khomarele thepa leha e le efe.Khokahano ea likhohlano ea thepa ea mochini e nyane haholo, ke 1/5 feela ea polyethylene, e leng karolo ea bohlokoa ea bokaholimo ba perfluorocarbon.Ho feta moo, hobane matla a ketane ea fluorine-carbon intermolecular a tlase haholo, PTFE ha e khomarele.
E seng chefo- Ka ho se sebetse ha 'mele, ho kenngoa ha nako e telele ha methapo ea mali le litho tsa' mele ntle le karabelo e mpe.
Lenane la ts'ebeliso ea poleiti ea PTFE ke ka tsela e latelang:
1. E sebelisa litšoaneleho tsa coefficient e tlase ea likhohlano, e sebelisetsoa ho cheka oli ea offshore derrick slide veneer, dock slide veneer, river dam gate gate slide veneer, bridge telescopic support slide veneer, lisebelisoa tse fapaneng tsa mochini, mechini e tenang, Grinder, planer sliding guide. , joalo-joalo.
2. Ka ho sebelisa thepa ea eona e se nang thupa, e sebelisoa indastering ea tsoekere, indasteri ea liaparo, lijo, lebanta le tsamaisang ho baka koae, indasteri ea khatiso le ea ho daea e thibelang kutu e thibelang kutu ea lirolara tse fapaneng tsa tataiso, jj.
3. Tšebeliso ea li-motors tsa dielectric e na le ts'ebetso e babatsehang 'me e sebelisoa liteisheneng tsa motlakase oa mocheso, lisele tsa electrolytic, mehele ea ho tiisa, lipotoloho tse hatisitsoeng ka lisebelisoa tsa elektronike le liindasteri tsa lik'homphieutha tsa elektronike, li-substrates tse nang le koporo, likarolo tse sa tšoaneng tsa lisebelisoa le lisebelisoa tse khethehileng.
4. Ho nka monyetla ka botsitso ba eona bo botle ba lik'hemik'hale, e ka sebelisoa haholo bakeng sa li-gaskets, linings, li-valve disc, le diaphragm tsa li-valve tse kholo indastering ea petroleum, ea lik'hemik'hale le ea lik'hemik'hale, hammoho le masela a likepe tse fapaneng tse arabelang, litanka tsa polokelo. , le reaction towers, distribution plate, joalo-joalo.
Tšebeliso ea poleiti ea PTFE e fetotsoeng
PTFE poleiti e fetotsoengke thepa e ratoang bakeng sa lesela le sa bolaeeng ke kutu, joale libaka tsa ts'ebeliso ea poleiti ea PTFE e fetotsoeng ke efe?
E le thepa ea ho tiisa, lipoleiti tsa PTFE tse fetotsoeng li sebelisoa haholo ka mechine, petrochemical, lipalangoang, masela le indasteri ea kaho.Ho ea ka khase permeability e khethiloeng ea poleiti ea PTFE ka mor'a phekolo, e ka sebelisoa e le thepa ea karohano ho khetha ho kenella ka khase kapa mokelikeli, haholo-holo ho sefa metsi a senyang.Lilemong tsa morao tjena, poleiti ea PTFE e fetotsoeng e 'nile ea sebelisoa e le setho sa maiketsetso,' me e tla sebelisoa likarolong tse sa tšoaneng nakong e tlang, e nang le tebello e ntle ea tsoelo-pele.
