Mafuta a Perfluoropolyether (PFPE) a Pampu Zopukutira

2025-04-25

Mafuta a Perfluoropolyether a PFPE ndi okhazikika pa kutentha, amalowa m'thupi, ndipo amagwira ntchito ndi zitsulo, ma polima a hydrogenated, mpweya ndi mpweya woopsa ngakhale pa kutentha kwambiri.

Mafuta a PFPE amapangidwira mwapadera zida zapampu za vacuum pomwe mawonekedwe awo apadera amapereka zabwino zambiri.

Ngati mukuvutikira kusankha mafuta opopera a vacuum oyenera pazosowa zanu, mwafika pamalo oyenera. Lero, tikuyang'ana kwambiri perfluoropolyether (PFPE) mafuta opaka pampu - kufotokoza mitundu ya mapampu omwe amagwira nawo ntchito bwino komanso momwe amasiyanirana ndi mafuta ena a vacuum pump.

1.Ndi Mitundu Yanji Ya Mapampu A Vacuum Amagwira Ntchito Bwino Ndi Mafuta a PFPE?

Mapampu a Rotary Vane Vacuum

Mafuta a PFPE amapambana pamapampu a rotary vane popereka chisindikizo chapadera pakati pa vanes ndi stator, kuchepetsa kukangana, ndikusunga magwiridwe antchito ngakhale pamavuto.Fomblin Y Mafuta a 25/6 a PFPE ndi mafuta amtundu wa PFPF vacuum vacuum mapampu a Vanes vacuum.

Mapampu a Diffusion

Kuthamanga kwa nthunzi kochepa kwambiri kwamafuta a PFPE kumawapangitsa kukhala abwino pamapampu ophatikizira komwe kubweza kumbuyo kuyenera kuchepetsedwa. Amakhala okhazikika pa kutentha kwakukulu kofunikira kuti apange ndege ya nthunzi.

Mapampu a Turbomolecular

Pokhala ndi zodzola m'mapampu a turbomolecular, mafuta a PFPE amapereka magwiridwe antchito ofunikira ndikutulutsa pang'ono, kuwonetsetsa kuti ma vacuum apamwamba kwambiri atha kukwaniritsidwa.

2.Makhalidwe Ofunika a PFPE Vacuum Mafuta

√ Kutsika kwambiri kwa nthunzi: Nthawi zambiri 10-10 mpaka 10-13 torr pa 20°C, zomwe zimathandiza kuti vacuum igwire ntchito kwambiri.

√ Kusakhazikika kwa Chemical: Kusamva mankhwala ambiri, ma acid, maziko, ndi oxidizing agents.

√ Kutentha kwakukulu: kumatha kugwiritsidwa ntchito pa kutentha kwambiri komanso kutentha kochepa.

√ Kukana kwa radiation: Imasunga katundu pansi pa cheza cha ionizing.

√ Zosayaka: Sizidzawotcha kapena kuthandizira kuyaka, kupititsa patsogolo chitetezo.

√ Moyo wautali wautumiki: Imachepetsa pafupipafupi kukonza komanso ndalama zogwirira ntchito.

√ Kugwirizana kwa okosijeni: Ndiotetezeka kugwiritsidwa ntchito m'malo okhala ndi okosijeni wopanda chiwopsezo cha okosijeni.

Ntchito Komwe Mafuta a PFPE Ndiwofunika

√ Kupanga ma semiconductor: Komwe vacuum yokwera kwambiri komanso ukhondo wamankhwala ndizofunikira.

√ Kafukufuku wa labotale: Pazida zodziwika bwino zasayansi zomwe zimafuna kuipitsidwa pang'ono.

√ Zipinda zofananira mumlengalenga: Kumene mikhalidwe yoipitsitsa ndi kudalirika ndizofunikira kwambiri.

√ Chemical processing: M'madera okhala ndi mankhwala aukali ndi mpweya.

√ Kupanga mankhwala: Kumene kuyeretsedwa kwa mankhwala ndikofunikira.

√ Kugwiritsa ntchito zida za nyukiliya: Chifukwa cha kukana ma radiation.

√ Ntchito ya okosijeni: Kumene mafuta wamba angabweretse ngozi.
