PTFE raschig nplhaib yog ib qho xoob ntim. Cov duab yooj yim. Nws yog ib lub voj voog uas nws qhov siab sib npaug rau nws txoj kab uas hla. Rasicyclic nplhaib muaj kev tiv thaiv zoo heev rau cov kua qaub thiab cua sov, tiv thaiv ntau yam inorganic acids, organic acids thiab cov organic solvents tshwj tsis yog hydrofluoric acid corrosion, tuaj yeem siv rau ntau yam kub siab.
PTFE Polytetrafluoroethylene Pall nplhaib (100% PTFE ntshiab) yog ib hom yas tshwj xeeb random ntim tsim los rau kev ua haujlwm tshwj xeeb thiab daim ntawv thov.
Cov txiaj ntsig ntawm PTFE raw khoom
1. Zoo heev corrosion resistant
2. Zoo heev kub resistant: los ntawm -200 degrees rau +260 degrees
3. Siv sijhawm ntev
4. Lub zog tsis tshua muaj zog, hydrophobic heev
Cov yam ntxwv ntawm ob hom rings
| Cov yam ntxwv | PTFE raschig rings | PTFE pall rings |
| Cov qauv | Kem khoob, phab ntsa nyias. | Txhim kho ntawm lub nplhaib raschig, muaj qhov rais ntawm phab ntsa, thiab ib feem ntawm lub qhov rais iav khoov mus rau hauv nruab nrab ntawm lub nplhaib. |
| Cov khoom siv hloov pauv kua thiab pawg | 1. Txoj kev roj-kua ruaj khov, 2. Thaj chaw me me zoo. 3. loj resistant,qis flux. 4. kev hloov pauv tsawg | 1. txhim kho cov roj-kua faib 2. Thaj chaw loj zoo, siv tau zoo 3. qis dua tiv taus,txhim kho qhov flux 4. Kev hloov pauv zoo dua, siab dua 30-50% ntawm tib qhov loj me |
| Cov txiaj ntsig tseem ceeb |
2. Thov rau qhov ua tau zoo dua, kev tiv taus corrosion siab. | 1. Kev ua haujlwm zoo, muaj zog ntau, poob siab tsawg 2. Muaj peev xwm tiv thaiv kev txhaws zoo dua |
| Daim Ntawv Thov | 1. Kev nqus thiab ntxuav cov khoom siv corrosive muaj zog. 2. Tiv thaiv kev xeb nrog cov kev cai qis rau kev poob siab thiab kev ua haujlwm zoo
. | 1. Kev sib xyaw ua ke, kev nqus, kev tshem tawm thiab kev txhuam cov pej thuam rau cov tshuaj corrosive heev (xws li sulfuric acid, chlor-alkali, hydrofluoric acid, bromine thiab lwm yam lag luam) 2. Yuav tsum tau kho cov roj khib nyiab nrog qhov siab poob qis thiab muaj peev xwm ua haujlwm tau zoo (xws li kev nqus cov pa roj acid). |
