Teflon Cov yam ntxwv

1. Tsis nplaum: Yuav luag txhua qhov tshuaj tsis cuam tshuam rau PTFE zaj duab xis. Cov duab nyias nyias kuj tseem ua rau pom cov yeeb yam zoo.

2. Thaum tshav kub kub ua hauj: PTFE txheej zaj duab xis muaj kev tiv tshav kub zoo thiab tsis kub tsis kam. Nws tuaj yeem tiv taus qhov kub siab mus rau 300 ℃ hauv lub sijhawm luv luv, thiab feem ntau tuaj yeem siv tsis tu ncua ntawm 240 ℃ ~ 260 ℃. Nws muaj qhov zoo tshaj plaws thermal stability. Nws tuaj yeem ua haujlwm thaum txias txias tsis muaj embrittlement thiab tsis yaj ntawm qhov kub.

3. Cov cuab yeej swb: PTFE txheej zaj duab xis muaj qhov sib txhuam tsis tshua muaj siab. Kev sib txhuam coefficient hloov thaum lub load tau swb, tab sis tus nqi tsuas yog ntawm 0.05-0.15.

4. Ya raws tsis kam: Lub nplaim ntawm PTFE txheej zaj duab xis tsis lo rau dej thiab roj, thiab nws tsis yooj yim lo rau cov tshuaj thaum lub sijhawm ua haujlwm. Yog tias muaj qhov me me ntawm cov av, nws tuaj yeem tshem tawm los ntawm kev ntxuav tawm yooj yim. Lub sijhawm luv, txuag lub sijhawm ua haujlwm thiab txhim kho kev ua haujlwm.

5. Hnav tsis kam: Nyob rau hauv siab load, nws muaj zoo hnav tsis kam. Hauv qab qee qhov thauj khoom, nws muaj qhov zoo ob ntawm kev hnav ua haujlwm thiab tsis tuav.

6. Corrosion tsis kam: PTFE tsis yog corroded los ntawm tshuaj lom neeg, thiab muaj peev xwm tiv taus txhua tus muaj zog acids (suav nrog aqua regia), muaj zog oxidants, thiab txo tshwj tsis yog molten alkali hlau, fluorinated media, thiab sodium hydroxide siab dua 300 ° C Lub luag haujlwm ntawm tshuaj lom neeg thiab ntau yam organic solvents tuaj yeem tiv thaiv qhov chaw ntawm txhua yam ntawm kev xeb
