Ukuguga kwe-hose yeTeflon akufanele kuhoywe

Iityhubhu zeTeflon ziityhubhu ze-fluoroplastic ezenziwe ngezinto ze-polytetrafluoroethylene ngokuxuba, ukwenza i-embryo, ukucinezela okubandayo, ukuthambisa kunye nokupholisa.

Iityhubhu zeTeflon zineempawu ezintle:

①I-coefficient ephantsi yokhuhlane;

②Ukunganyangeki kwe-Corrosion: ukuxhathisa kwe-asidi eqinile kunye ne-alkali, kwaye phantse zonke iikhemikhali aziphenduli (kwiqondo lokushisa eliphezulu kunye ne-fluorine kunye ne-alkali metal reaction), inokuxhathisa "i-Aqua regia" i-corrosion;

③Ukuzicoca: i-polytetrafluoroethylene kunzima ukubambelela kuyo;

④ Ayinakutsha;

⑤Ukumelana nobushushu obuphezulu: I-PTFE iqondo lobushushu leteflon linokufikelela -70 ° C ~ 260 ° C;

⑥Ukumelana okuphezulu: ityhubhu yeTeflon enokumelana okuphezulu, ukusebenza kakuhle kokugquma;

⑦ Ukuchasana nokuguga: I-Teflon Tube yokuchasana nokuguga ibalaseleyo, ubomi benkonzo ende.

Ukuguga kwe-hose ye-PTFE ayinakungahoywa, ukusebenza kweemveliso kuya kuncitshiswa emva kokuguga, ngoko, ukuveliswa kwexesha elide, kufuneka siphumeze uluhlu lwamanyathelo okuthintela.

Iteyiphu encamathelayo yeemveliso ityhubhu yeTeflon ihlanjululwe ngenkqubo yokunyanga isulfure. Ukumelana nobushushu be-vulcanizate yayo kunokuphuculwa ngokunciphisa okanye ukunqanda ukusetyenziswa kwesulfure ye-elemental, enokunciphisa okanye isuse i-polysulfide cross-linking kwaye ivelise i-sulfure enye okanye i-disulfide cross-linking.

Ukusetyenziswa kweperoxide kuyimfuneko ukufezekisa ukuxhathisa ubushushu obuhle, njengoko ukunyanga ngeperoxide kuvelisa i-carbon-carbon crosslinks ethermostable. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwezinye izongezo xa usebenzisa i-peroxide. Ngokomzekelo, ukhetho lwe-antioxidants kufuneka lube lukhuni ngakumbi, njengoko uninzi lwazo luphazamisa i-peroxide, i-vulcanization.

Ukongezelela, xa usebenzisa i-peroxide, nciphisa inani le-acid fillers ukukhusela i-peroxide cations ekuboleni, okubangela ukuba i-vulcanization ephantsi ye-hose ye-high-pressure hose (ngendlela yobunzima obuphantsi, i-modulus ephantsi kunye nesethi yoxinzelelo oluphezulu) . Ukongeza iikhompawundi ezisisiseko, ezifana ne-zinc oxide okanye i-magnesium oxide, apho kunokwenzeka, kunokuphucula ukusebenza kakuhle kwe-peroxide. Usenempembelelo yeoli yeparafini ingcono, ufuna ukunqanda ukusebenzisa ioyile yehydrocarbon enevumba elimnandi kunye nesinyibilikisi.
