Perfluoropolyether PFPE roj yog thermally ruaj khov, chemically inert, thiab sib xws nrog hlau, hydrogenated polymers, oxygen thiab aggressive gases txawm nyob rau hauv high kub.

PFPE roj tau tsim tshwj xeeb rau cov twj tso kua mis tshwj xeeb uas lawv cov khoom tshwj xeeb muab cov txiaj ntsig zoo.

Yog tias koj tawm tsam xaiv lub tshuab nqus tsev twj tso kua mis zoo rau koj cov kev xav tau, koj tau tuaj rau qhov chaw zoo. Niaj hnub no, peb tab tom tsom mus rau perfluoropoyether (PFPE) lub tshuab nqus tsev twj roj - piav qhia seb hom twj twg lawv ua haujlwm zoo tshaj plaws nrog thiab lawv txawv li cas ntawm lwm lub tshuab nqus tsev twj tso kua mis.

1.Dab tsi ntawm lub tshuab nqus tsev twj ua haujlwm zoo tshaj plaws nrog PFPE Roj?

Rotary Vane Nqus Pumps

PFPE cov roj ua tau zoo nyob rau hauv cov twj siv hluav taws xob los ntawm kev muab kev sib khi tshwj xeeb ntawm cov vanes thiab stator, txo kev sib txhuam, thiab tswj kev ua haujlwm zoo txawm tias nyob rau hauv kev ua haujlwm nyuaj.Fomblin Y 25/6 PFPE roj yog cov PFPF lub tshuab nqus tsev twj roj rau Vanes lub tshuab nqus tsev twj.

Diffusion Pumps

Qhov tsis tshua muaj vapor siab ntawm PFPE roj ua rau lawv zoo tagnrho rau diffusion twj uas backstreaming yuav tsum raug txo kom tsawg. Lawv tswj kev ruaj ntseg ntawm qhov kub thiab txias uas yuav tsum tau ua rau vapor jet tsim.

Turbomolecular Pumps

Rau cov kabmob lubrication hauv cov twj tso kua mis turbomolecular, PFPE cov roj muab qhov tsim nyog ua haujlwm nrog tsawg kawg nkaus outgassing, kom ntseeg tau tias lub tshuab nqus tsev siab tshaj plaws tuaj yeem ua tiav.

2. Cov yam ntxwv tseem ceeb ntawm PFPE Nqus Roj Roj

√ Tsis tshua muaj vapor siab: Feem ntau 10-10 txog 10-13 torr ntawm 20 ° C, ua kom lub tshuab nqus tsev ua haujlwm siab.
√ Chemical inertness: Resistant mus rau feem ntau chemicals, acids, bases, thiab oxidizing agents.
√ Kev ua tau zoo ntawm qhov kub thiab txias: nws tuaj yeem siv rau qhov kub thiab txias heev.
√ Radiation kuj: Tswj cov khoom nyob rau hauv raug rau ionizing hluav taws xob.
√ Non-flammable: Yuav tsis hlawv lossis txhawb kev sib tsoo, txhim kho kev nyab xeeb.
√ Lub neej ua haujlwm ntev: Txo kev saib xyuas zaus thiab cov nqi khiav haujlwm.
√ Oxygen compatibility: Muaj kev nyab xeeb rau kev siv nyob rau hauv qhov chaw muaj pa oxygen uas tsis muaj kev pheej hmoo ntawm oxidation.

Daim ntawv thov qhov twg PFPE Roj yog qhov tseem ceeb

√ Semiconductor manufacturing: Qhov twg ultra-high nqus thiab tshuaj huv huv yog qhov tseem ceeb.

√ Kev tshawb fawb hauv chaw soj nstuam: Rau cov khoom siv tshawb fawb rhiab heev uas yuav tsum muaj kev sib kis tsawg.

√ Qhov chaw simulation chambers: Qhov chaw huab cua thiab kev ntseeg siab yog qhov tseem ceeb.

√ Kev ua tshuaj lom neeg: Hauv ib puag ncig nrog cov tshuaj lom neeg thiab cov pa phem.

√ Pharmaceutical ntau lawm: Qhov twg cov khoom purity yog qhov tseem ceeb.

√ Nuclear daim ntaub ntawv: Vim muaj hluav taws xob tiv taus.

√ Oxygen kev pab cuam: qhov twg cov pa roj yuav ua rau muaj kev nyab xeeb.
