Qhov sib txawv tseem ceeb ntawm ETP thiab TFS yog nyob rau hauv lawv cov kev siv thiab cov yam ntxwv.ETP feem ntau yog siv los tsim cov kaus poom zaub mov thiab cov kaus poom dej haus, thaum TFS feem ntau yog siv los tsim cov kaus poom sib sib zog nqus thiab cov khoom siv hluav taws xob. Cov txheej txheem txheej ntawm ETP suav nrog steel puag, tin txheej, tin oxide txheej thiab roj zaj duab xis, thaum txheej txheej ntawm TFS suav nrog steel puag, hlau chromium txheej, chromium oxide txheej thiab roj zaj duab xis. Cov yam ntxwv ntawm ETP suav nrog kev ua haujlwm zoo corrosion, zoo weldability thiab kev ua haujlwm zoo, thaum cov yam ntxwv ntawm TFS suav nrog kev ua haujlwm kub zoo, zoo xim adhesion thiab zoo heev los tiv thaiv sulfurization.
Cov txheej txheem txheej ntawm ETP muaj plaub txheej: steel puag, tin txheej, tin oxide txheej thiab roj zaj duab xis. Lub hauv paus steel muab lub zog thiab formability, tin txheej muab corrosion kuj thiab lubrication, tin oxide txheej txhim kho tshuaj stability, thiab cov roj zaj duab xis ntxiv txhim khu lubricity. Cov txheej txheem txheej ntawm TFS kuj suav nrog steel puag, tab sis lub ntsiab txheej yog hlau chromium, chromium oxide txheej muab cov tshuaj lom neeg ruaj khov thiab tiv thaiv corrosion, thiab cov roj zaj duab xis txhim kho lubricity.
Nyob rau hauv cov nqe lus ntawm cov khoom, ETP muaj zoo heev corrosion kuj, zoo weldability thiab zoo heev processability, thiab yog haum rau tsim khoom noj thiab haus cov kaus poom. TFS muaj cov cua kub zoo heev, cov xim zoo adhesion thiab zoo heev los tiv thaiv sulfurization, thiab tsim nyog rau kev tsim cov kaus poom sib sib zog nqus thiab cov khoom siv hluav taws xob.
