Masiku ano, mankhwala ambiri kuima pa chitukuko cha umisiri ndi mafakitale, ndi PTFE chubu ndi chimodzi mwa zinthu zimenezi kuti mbali yofunika m'madera osiyanasiyana.Koma munayamba mwazindikira kukalamba kwaPTFE machubu?Kuchita kwa machubu a PTFE kudzachepetsedwanso akakalamba.Kotero mndandanda wa miyeso iyenera kuchitidwa kuti tipewe kukalamba kumapeto kwa kupanga machubu a PTFE.Kukalamba kwa machubu a PTFE ndi kwachilengedwe ndipo sikungalephereke, koma chinthu chokhacho chomwe mungachite ndikuchepetsa ukalamba. PTFE machubu.Pofuna kuchepetsa ukalamba wa machubu a PTFE, muyenera kulimbikitsa kukonza pogwiritsa ntchito machubu a PTFE ndikuchitapo kanthu kuti mupewe izi.PanoBesteflon akukupatsirani njira zazikulu zinayi zochepetsera kukalamba kwa chubu lanu la PTFE.
1. Posankha zinthu sizing za PTFE machubu, muyenera kugwiritsa ntchito sulfure kuchiritsa dongosolo ngati n'kotheka.Chifukwa cha kukana kutentha kwa mphira wake wopangidwa ndi vulcanized, imatha kusinthidwa ndikuchepetsa kapena kupewa kugwiritsa ntchito sulfure yoyambira, yomwe imatha kuchepetsa kapena kuchotsa ma crosslinks a polysulfide ndikupanga ma crosslinks ambiri a monosulfide kapena disulfide, motero amachepetsa kukalamba.PTFE machubu.
2. Kuonetsetsa kuti zinthuzo zimakwaniritsa kutentha komwe kumafunidwa, kugwiritsa ntchito peroxide kumafunika.Pachifukwa ichi, peroxide vulcanization imapanga carbon ndi kukhazikika kwabwino kwa kutentha ndi carbon cross-linking bonds.
PTFE chubu wopanga amanenanso kuti muyenera kulabadira kwambiri zina zowonjezera ntchito peroxides.Mwachitsanzo, kusankha kwa antioxidants kuyenera kukhala kolimba kwambiri, chifukwa ambiri aiwo amasokoneza vulcanization ya peroxides.Choncho, mukhoza kugwiritsa ntchito mafuta a parafini, chowonjezera chothandiza chomwe sichidzasokoneza peroxide vulcanization.
3. Komanso, pofuna kupewa partitioning wa peroxide cation ndi kupewa vulcanization otsika kwambiri payipi mkulu-anzanu (kusonyezedwa ndi m'munsi kuuma, m'munsi modulus ndi apamwamba psinjika ndi mapindikidwe nthawi yaitali), muyenera kugwiritsa ntchito peroxide kuchepetsa kuchuluka kwa acidic filler.Ngati n'kotheka, kuwonjezera kwa mankhwala amchere (mwachitsanzo, nthaka okusayidi kapena magnesium oxide) nthawi zambiri kumapangitsa kuti peroxide ikhale yabwino kwambiri.
4. PopangaPTFE machubu, zowonjezera zina zitha kuwonjezeredwa, monga ma antioxidants, ndi zinthu zamchere, ndi zina zambiri, kuti apititse patsogolo kulumikizana bwino kwa peroxides ndikuchedwetsa ukalamba waPTFE machubu.
