Khetho ea litiiso

Khetho eaThepa ea tiisos:

Tse sebelisoang hangata thepa ea tiisok'hamphani ea rona ke Polyurethane, rabara ea Nitrile, Fluororubber, PTFE, joalo-joalo, 'me lisebelisoa tse fapaneng li na le litšobotsi tse fapaneng, tse latelang:

(1) Polyurethane e na le khanyetso e ntle ea ho roala le sekhahla se senyenyane sa compression deformation, 'me hangata e sebelisoa liketsahalong tse matla tsa ho tiisa.E ka mamella mocheso o sebetsang oa -35-100 ℃, 'me e loketse oli ea hydraulic e thehiloeng ho petroleum.Ntle le lisebelisoa tse tsoang linaheng tse ling, e na le khanyetso e fokolang ea hydrolysis 'me e ke ke ea sebelisoa bakeng sa oli ea hydraulic e thehiloeng metsing, e kang metsi glycol.

(2) Lisebelisoa tsa rabara tsa Nitrile li na le ho se sebetse hantle, 'me ka kakaretso li sebelisoa libakeng tsa ho tiisa tse tsitsitseng, kapa li kopantsoe le lisebelisoa tse ling tse sa sebetsaneng ho etsa mehele e tiileng ea ho tiisa, e kang mehele ea Glyd le litiiso tsa Mohato.E khona ho mamella mocheso o sebetsang oa -10-80 ℃, 'me e lumellana hantle le oli e fapaneng ea hydraulic ntle le phosphate ester.

(3) Thepa ea fluororubber e na le khanyetso e mpe ea ho roala le bokhoni ba anti-extrusion.Ka kakaretso e sebelisoa maemong a tiileng a ho tiisa, kapa a kopantsoe le lisebelisoa tse ling tse sa sebetseng ho etsa selikalikoe sa ho tiisa se matla.Ha e sebelisoa bakeng sa ho tiisa ka matla feela, selikalikoe sa ho boloka se lokela ho eketsoa ho thibela ho tsoa.E khona ho mamella mocheso oa ho sebetsa oa -20-160 ° C, 'me e ka sebetsa sebakeng se phahameng sa mocheso oa 200 °C ka nako e khutšoanyane,' me e lumellana hantle le lioli tse sa tšoaneng tsa hydraulic.

(4) thepa ea PTFE e na le khanyetso e ntle ea ho roala le bokhoni ba anti-extrusion.Hangata e sebelisoa hammoho le thepa ea rabara ho etsa tiiso e matla.Leha ho le joalo, ka lebaka la sekhahla sa eona se seholo sa compression deformation, se ka baka ho lutla ho hoholo ha se sebelisoa ka khatello e tlase.Ka kakaretso e sebelisoa tikolohong ea mocheso o phahameng ka holimo ho 25MPa.E khona ho mamella mocheso o sebetsang oa -40-135 ℃, 'me e lumellana hantle le lioli tse fapaneng tsa hydraulic.
