Kukalamba kwa payipi ya Teflon sikuyenera kunyalanyazidwa

Machubu a Teflon ndi machubu a fluoroplastic opangidwa kuchokera ku zinthu za polytetrafluoroethylene posakaniza, kupanga mluza, kukanikiza kozizira, sintering ndi kuziziritsa.

Machubu a Teflon ali ndi zinthu zabwino kwambiri:

①Kugundana kocheperako;

②Kukana kwa dzimbiri: kukana kwa asidi ndi alkali, ndipo pafupifupi mankhwala onse sachita (pa kutentha kwambiri ndi fluorine ndi zitsulo zamchere), amatha kukana "Aqua regia" dzimbiri;

③Kudziyeretsa: polytetrafluoroethylene ndizovuta kumamatira;

④Osayaka;

⑤Kutentha kwakukulu kwa kutentha: PTFE teflon zinthu kutentha kumatha kufika -70 ° C ~ 260 ° C;

⑥Kukaniza Kwambiri: chubu cha Teflon chokhala ndi kukana kwakukulu, ntchito yabwino kwambiri yotchinjiriza;

⑦ Anti-kukalamba: Teflon Tube anti-aging performance ndi yabwino kwambiri, moyo wautali wautumiki.

Kukalamba kwa payipi ya PTFE sikunganyalanyazedwe, ntchito ya mankhwala idzachepetsedwa pambuyo pa ukalamba, kotero, kupanga mochedwa, tiyenera kugwiritsa ntchito njira zingapo zopewera.

Tepi yomatira ya mankhwala a Teflon chubu imatenthedwa ndi njira yochiritsa sulfure. Kutentha kukana kwake vulcanizate akhoza bwino ndi kuchepetsa kapena kupewa ntchito elemental sulfure, amene angathe kuchepetsa kapena kuthetsa polysulfide mtanda yolumikizira makamaka kutulutsa sulfure umodzi kapena disulfide mtanda yolumikizira.

Kugwiritsa ntchito peroxide ndikofunikira kuti mukwaniritse bwino kutentha, chifukwa kuchiritsa ndi peroxide kumatulutsa ma crosslinks a carbon-carbon omwe amatha kutentha kwambiri. Chisamaliro chapadera chiyenera kuperekedwa kwa zowonjezera zina mukamagwiritsa ntchito peroxide. Mwachitsanzo, kusankha kwa antioxidants kuyenera kukhala kolimba kwambiri, chifukwa ambiri aiwo amasokoneza peroxide, vulcanization.

Komanso, pamene ntchito peroxide, kuchepetsa kuchuluka kwa asidi fillers kupewa peroxide cations kuwola, chifukwa otsika vulcanization wa mkulu-anzanu payipi (mu mawonekedwe a m'munsi kuuma, m'munsi modulus ndi apamwamba psinjika anapereka) . Kuonjezera mankhwala ofunikira, monga zinc oxide kapena magnesium oxide, ngati kuli kotheka, nthawi zambiri kumapangitsa kuti peroxide ikhale yabwino kwambiri. Komabe ndi parafini mafuta kwenikweni bwino, ndikufuna kupewa ntchito onunkhira hydrocarbon mafuta ndi zosungunulira.
