Amashubhu e-Teflon amashubhu e-fluoroplastic enziwe ngezinto ze-polytetrafluoroethylene ngokuxuba, ukwenza umbungu, ukucindezela okubandayo, ukucwilisa nokupholisa.
Amashubhu e-Teflon anezakhiwo ezinhle kakhulu:
①I-coefficient yokungqubuzana okuphansi;
②Ukumelana nokugqwala: ukumelana ne-asidi eqinile ne-alkali, futhi cishe wonke amakhemikhali awasabeli (emazingeni okushisa aphezulu kanye ne-fluorine nokusabela kwensimbi ye-alkali) , angamelana nokugqwala kwe-“Aqua regia”;
③Ukuzihlanza: i-polytetrafluoroethylene kunzima ukunamathela kuyo;
④Akushi;
⑤Ukumelana nokushisa okuphezulu: izinga lokushisa le-PTFE teflon lingafinyelela -70 ° C ~ 260 ° C;
⑥Ukumelana Okuphezulu: Ishubhu ye-Teflon enokumelana okuphezulu, ukusebenza okuhle kakhulu kokufakwa;
⑦Ukuvimbela ukuguga: Ukusebenza kwe-Teflon Tube anti-aging kuhle kakhulu, impilo ende yesevisi.
Ukuguga kwe-hose ye-PTFE akunakunakwa, ukusebenza kwemikhiqizo kuzoncishiswa ngemuva kokuguga, ngakho-ke, ukukhiqizwa kwesikhashana, kufanele sisebenzise uchungechunge lwezinyathelo zokuvimbela.
Itheyiphu yokunamathisela yemikhiqizo yeshubhu yeTeflon ivulwa ngohlelo lokuphulukisa isulfure. Ukumelana nokushisa kwe-vulcanizate yayo kungathuthukiswa ngokunciphisa noma ngokugwema ukusetshenziswa kwe-elemental sulfur, enganciphisa noma iqede i-polysulfide cross-linking futhi ikakhulukazi ikhiqize isibabule esisodwa noma i-disulfide cross-linking.
Ukusetshenziswa kwe-peroxide kuyadingeka ukuze kuzuzwe ukumelana nokushisa okuhle, njengoba ukuphulukisa nge-peroxide kukhiqiza i-carbon-carbon crosslinks ekwazi ukushisa kakhulu. Ukunakwa okukhethekile kufanele kukhokhwe kwezinye izithasiselo lapho usebenzisa i-peroxide. Isibonelo, ukukhethwa kwama-antioxidants kudinga ukuqina, njengoba amaningi awo aphazamisa i-peroxide, i-vulcanization.
Ukwengeza, lapho usebenzisa i-peroxide, nciphisa inani lezigcwalisi ze-asidi ukuvimbela i-cations ye-peroxide ekuboleni, okuholela ekuvuthweni okuphansi kwe-hose ephezulu yokucindezela (ngesimo sokuqina okuphansi, i-modulus ephansi kanye nesethi yokucindezela okuphezulu) . Ukwengeza izinhlanganisela eziyisisekelo, njenge-zinc oxide noma i-magnesium oxide, lapho kungenzeka khona, ngokuvamile kungathuthukisa ukusebenza kahle kwe-peroxide. Namanje babe uwoyela kapharafini umphumela kungcono, bafuna ukugwema ukusebenzisa elimnandi hydrocarbon uwoyela kanye solvent.
