Kule mihla, iimveliso ezininzi zigqamile kuphuhliso lobuchwepheshe kunye neshishini, kwaye ityhubhu ye-PTFE yenye yezi mveliso zidlala indima ebalulekileyo kwiinkalo ezahlukeneyo.Kodwa ngaba ukhe waqaphela ukuguga kweIityhubhu ze-PTFE?Ukusebenza kweetyhubhu ze-PTFE kuya kuncitshiswa emva kokuguga.Ngoko uluhlu lwamanyathelo kufuneka luthathwe ukuthintela ukuguga kwinqanaba lokugqibela lokuveliswa kweetyhubhu ze-PTFE.Ukuguga kweetyhubhu ze-PTFE kuyindalo kwaye akunakuthintelwa, kodwa inye kuphela into onokuyenza kukucothisa isantya sokuguga. Iityhubhu ze-PTFE.Ukunceda ukucotha izinga lokuguga kweetyhubhu ze-PTFE, kufuneka uqinise ukugcinwa ekusebenziseni iityhubhu ze-PTFE kwaye uthathe uthotho lwamanyathelo okuthintela le meko.AphaBesteflon ikunika iindlela ezine eziphambili zokucothisa isantya sokuguga setyhubhu ye-PTFE.
1. Xa ukhetha imathiriyeli yokulinganisa yeetyhubhu ze-PTFE, kufuneka usebenzise inkqubo yokunyanga isulfure xa kunokwenzeka.Ngenxa yokunganyangeki kobushushu kwerabha yayo evulcanized, inokuguqulwa ngokunciphisa okanye ukunqanda ukusetyenziswa kwesulfure eyisiseko, enokunciphisa okanye isuse i-polysulfide crosslinks kwaye ivelise ikakhulu i-monosulfide okanye i-disulfide crosslinks, ngaloo ndlela icothise ukuguga.PTFE imibhobho.
2. Ukuqinisekisa ukuba izinto eziphathekayo zifezekisa ukumelana nokushisa okufunwayo, ukusetyenziswa kweperoxide kuyadingeka.Kule meko, i-peroxide vulcanization ivelisa i-carbon ngokuzinza okungcono kwe-thermal kunye ne-carbon cross-linking bonds.
Umenzi wetyhubhu we-PTFE ukwaqaphela ukuba kufuneka uhlawule ngokukodwa kwezinye izongezo ekusebenziseni iiperoxides.Umzekelo, ukhetho lwee-antioxidants kufuneka lube ngqongqo ngakumbi, njengoko uninzi lwazo luphazamisana ne-vulcanization yeperoxides.Ngoko ke, ungasebenzisa ioli yeparafini, isongezo esisebenzayo esingayi kuphazamisa i-peroxide vulcanization.
3. Ukongezelela, ukwenzela ukuthintela ukwahlukana kwe-peroxide cation kwaye ugweme i-vulcanization ephantsi kakhulu ye-hose ephezulu yoxinzelelo (eboniswe ngobunzima obuphantsi, i-modulus ephantsi kunye nokunyanzeliswa okuphezulu kunye nokuguqulwa kwexesha elide), kufuneka usebenzise i-peroxide ukuze unciphise. ubungakanani be-acidic filler.Ukuba kunokwenzeka, ukongezwa kwe-alkaline iikhompawundi (umz. i-zinc oxide okanye i-magnesium oxide) ngokuqhelekileyo iphucula i-cross-linking performance yeperoxide.
4. Xa kuveliswaPTFE Iityhubhu, ezinye izongezo zingongezwa, ezinje nge-antioxidants, kunye neekhompawundi zealkaline, njl.njl., ukuze kuphuculwe ukusebenza kakuhle kweperoxides kunye nokulibazisa ukuguga.PTFE imibhobho.
