Teflon machubhu machubhu efluoroplastic akagadzirwa kubva ku polytetrafluoroethylene zvinhu nekusanganisa, kugadzira embryo, kutonhora kudzvanya, sintering uye kutonhora.
Teflon machubhu ane zvakanakisa zvivakwa:
①Low friction coefficient;
②Corrosion resistance: yakasimba asidhi uye alkali kuramba, uye anenge ese makemikari haaite (papamusoro tembiricha uye fluorine uye alkali metal reaction) anogona kuramba "Aqua regia" corrosion;
③Kuzvichenesa: polytetrafluoroethylene yakaoma kunamatira;
④Isingabatike;
⑤Kupikisa kwekushisa kwepamusoro: PTFE teflon zvinhu tembiricha inogona kusvika -70 ° C ~ 260 ° C;
⑥Kupikisa Kwepamusoro: Teflon chubhu ine yakakwirira kuramba, yakanakisa insulation kuita;
⑦ Anti-kuchembera: Teflon Tube anti-aging performance yakanakisa, hupenyu hurefu hwebasa.
Kuchembera kwePTFE hose hakugone kuregererwa, kushanda kwezvigadzirwa kuchaderedzwa mushure mekukwegura, saka, kugadzirwa kwekupedzisira, tinofanira kushandisa matanho ekudzivirira.
Iyo inonamira tepi yeTeflon chubhu zvigadzirwa inopiswa nesarufa yekurapa system. Kupisa kwekudzivirira kwevulcanizate yayo kunogona kuvandudzwa nekudzikisa kana kudzivirira kushandiswa kwe elemental sulfur, iyo inogona kuderedza kana kubvisa polysulfide cross-linking uye kunyanya kuburitsa imwe sarufa kana disulfide cross-linking.
Kushandiswa kweperoxide kunodiwa kuti uwane kunaka kwekudzivirira kupisa, sezvo kurapa neperoxide kunogadzira carbon-carbon crosslinks iyo inonyanya kupisa. Kunyanya kukoshesa kunofanira kubhadharwa kune zvimwe zvinowedzera kana uchishandisa peroxide. Semuenzaniso, kusarudzwa kwe antioxidants kunoda kuve kwakanyanyisa, sezvo vazhinji vavo vanokanganisa peroxide, vulcanization.
Mukuwedzera, kana uchishandisa peroxide, kuderedza kuwanda kweasidhi fillers kudzivirira peroxide cations kubva pakuora, zvichikonzera kuderera kwevulcanization ye-high-pressure hose (nenzira yekuoma kwakadzika, modulus yakaderera uye yakakwirira compression set) . Kuwedzera makomisheni akakosha, akadai se zinc oxide kana magnesium oxide, pazvinogoneka, kazhinji inogona kuvandudza kugona kweperoxide. Uchiri neparafini mafuta mhedzisiro iri nani, kuda kudzivirira kushandisa anonhuwirira hydrocarbon mafuta uye solvent.
