Teflon raj yog cov raj fluoroplastic ua los ntawm cov khoom siv polytetrafluoroethylene los ntawm kev sib xyaw, embryo ua, txias nias, sintering thiab txias.
Teflon tubes muaj cov khoom zoo heev:
① Tsawg kev sib txhuam coefficient;
② Corrosion kuj: muaj zog acid thiab alkali tsis kam, thiab yuav luag txhua yam tshuaj tsis hnov mob (ntawm qhov kub thiab txias thiab fluorine thiab alkali hlau cov tshuaj tiv thaiv), tuaj yeem tiv taus "Aqua regia" corrosion;
③ Kev ntxuav tus kheej: polytetrafluoroethylene nyuaj rau lo rau;
④ Tsis Flammable;
⑤ Kub kub tsis kam: PTFE teflon khoom kub tuaj yeem ncav cuag -70 ° C ~ 260 ° C;
⑥High Resistance: Teflon raj nrog kev ua haujlwm siab, kev ua haujlwm zoo rwb thaiv tsev;
⑦Anti-aging: Teflon Tube los tiv thaiv kev laus ua tau zoo heev, ua haujlwm ntev.
Kev laus ntawm PTFE hose tsis tuaj yeem tsis quav ntsej, kev ua haujlwm ntawm cov khoom yuav raug txo qis tom qab kev laus, yog li, kev tsim khoom ntawm lub sijhawm lig, peb yuav tsum siv cov kev ntsuas los tiv thaiv.
Cov nplaum nplaum ntawm Teflon tube khoom yog vulcanized nrog sulfur curing system. Lub tshav kub tsis kam ntawm nws cov vulcanizate tuaj yeem txhim kho los ntawm kev txo lossis tsis txhob siv cov tshuaj sulfur, uas tuaj yeem txo lossis tshem tawm polysulfide cross-linking thiab tsuas yog tsim ib leeg sulfur lossis disulfide cross-linking.
Kev siv cov peroxide yog qhov tsim nyog kom ua tiav cov cua sov zoo, vim tias kev kho nrog peroxide ua rau cov pa roj carbon-carbon crosslinks uas muaj qhov kub thiab txias dua. Kev saib xyuas tshwj xeeb yuav tsum tau them rau lwm cov tshuaj ntxiv thaum siv peroxide. Piv txwv li, kev xaiv cov tshuaj antioxidants yuav tsum nruj dua, vim tias ntau ntawm lawv cuam tshuam nrog peroxide, vulcanization.
Tsis tas li ntawd, thaum siv peroxide, txo cov kua qaub kom tiv thaiv peroxide cations los ntawm decomposing, uas ua rau tsis tshua muaj vulcanization ntawm lub siab-siab hose (nyob rau hauv daim ntawv ntawm qis hardness, qis modulus thiab siab compression teeb). Ntxiv cov ntsiab lus tseem ceeb, xws li zinc oxide lossis magnesium oxide, qhov ua tau, feem ntau tuaj yeem txhim kho qhov kev sib txuas ntawm cov peroxide. Tseem muaj cov roj paraffin zoo dua, xav kom tsis txhob siv cov roj uas muaj ntxhiab hydrocarbon thiab hnyav.
