Kev ua tau zoo thiab kev siv Perfluoropoyether

Dab tsi yog perfluoropoyether?

Perfluoropolyether yog ib hom tshwj xeeb ntawm perfluoropolymer compound nrog qhov nruab nrab molecular hnyav li ntawm 500 txog 15,000. Tsuas muaj peb yam, C, F, thiab O, nyob rau hauv lub molecule. Nws muaj cov yam ntxwv ntawm tshav kub tsis kam, oxidation tsis kam, hluav taws xob tsis kam, corrosion kuj, thiab tsis-flammable. Nws yog dav siv nyob rau hauv tshuaj, hluav taws xob, hluav taws xob, mechanical, nuclear, thiab aerospace teb.

Perfluoropolyether yam ntxwv

1. Chemical inertness:

Perfluoropolyethers yog cov tshuaj inert rau feem ntau cov tshuaj corrosive xws li acids, bases thiab oxidants. Txawm li cas los xij, qee qhov nucleophiles (xws li ammonia), cov hlau nquag (xws li Na, K, Al, thiab lwm yam) thiab Lewis acids tuaj yeem decompose perfluoropolyethers thiab txo lawv cov thermal stability.

2. Thermal oxidation stability:

Thaum tsis muaj cov catalyst zoo, txawm tias muaj cov pa oxygen, perfluoropolyether tseem ruaj khov nyob rau hauv qhov ntau ntawm 270-300 degree . Nws qhov decomposition kub tuaj yeem ncav cuag 350-410 degree .

3. Lubrication zog:

Perfluoropolyether roj muaj cov coefficient tsawg ntawm kev sib txhuam, siab load kuj thiab zoo lubrication.

4. Compatibility:

Perfluoropolyether yog sib xws nrog ntau yam tshuaj, xws li oxidants (hydrogen peroxide, kua oxygen, thiab lwm yam), hydrocarbon fuels, unsymmetrical dimethylhydrazine, diethyltriamine, thiab lwm yam. Y-type thiab Z-type qauv perfluoropolyether muaj zoo compatibility nrog plastics thiab dag roj hmab.

5. nplaim tsis kam:

nplaim kuj yog ib qho tseem ceeb rau perfluoropoyether kom haum rau industrial thiab aviation lubricants. Piv nrog rau lwm hom roj nplua nyeem, perfluoropolyether yog qhov tsim nyog rau qhov kub thiab txias ua haujlwm hnyav.

6. Radiation kuj:

Perfluoropolyether muaj hluav taws xob zoo tiv thaiv thiab muaj qhov qis qis tshaj qhov kev loj hlob piv nrog hydrocarbons thiab silicone roj ntawm tib koob.

Daim ntawv thov Perfluoropolyether

Perfluoropolyether cov ntaub ntawv yog tsuas yog siv nyob rau hauv tshwj xeeb lubricants, industrial fluids, functional chemicals, thiab lwm yam.

1. Aerospace Kev Lag Luam:

Nyob rau hauv qhov chaw nqus tsev kiag li, qhov poob ntawm cov roj lubricating zoo tib yam yog siab heev, thaum cov roj perfluoropolyether poob qis heev nyob rau hauv cov xwm txheej hnyav ntawm lub tshuab nqus tsev, uas ua tau raws li cov kev cai rau kev siv mus ntev. Perfluoropolyether yog tsim rau lubrication thiab sealing ntawm lub tshuab fais fab thiab cov tshuab ua haujlwm raug rau qhov chaw, xws li cav, kiv cua bearings, longitudinal rudder adjusters, lub hwj chim log, scanning iav, iav twj tso kua mis, lub siab gauges, hlau pob qij txha thiab threaded fasteners.

2. Automobile Manufacturing Industry:

Perfluoropolyether roj tuaj yeem txo cov kev sib txhuam ntawm cov khoom, txo cov suab nrov, txhim kho cov neeg siv kev nplij siab, thiab muaj cua sov zoo thaum siv hauv tshuab.

3. Mechanical khoom kev lag luam:

Perfluoropolyether roj muaj cov roj lubrication zoo, thiab nws lub peev xwm ua yeeb yaj kiab yog peb zaug ntawm cov roj ntsha zoo tib yam. Nws yog anti-oxidation, tsawg-volatile, tsis-coking, tsis-carbon deposition, corrosion-resistant, hnav-resistant, thiab muaj zoo huab siab kuj. Nws tuaj yeem siv rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias heev. Feem ntau, nws tuaj yeem txuas lub neej ntawm bearings los ntawm 5 mus rau 50 zaug.

4. Kev lag luam hluav taws xob thiab hluav taws xob:

Perfluoropolyether yog tsim rau lubrication ntawm mechanical nqus twj tso kua mis nyob rau hauv ntau yam semiconductor integrated circuit ntau lawm txheej txheem xws li plasma etching, tshuaj vapor deposition thiab ion implantation. Nws kuj tseem tuaj yeem siv los ua cov roj nplua nyeem ntawm cov hard disks, disks thiab lwm cov ntaub ntawv sib nqus hauv cov twj siv hluav taws xob kom ntev lub neej ntawm cov khoom siv hluav taws xob.

5. Kev lag luam tshuaj:

Perfluoropolyether tuaj yeem siv los ua cov kua dej ua haujlwm rau ntau lub tshuab nqus tsev twj (xws li cov twj siv teb, cov twj turbomolecular, vapor diffusion twj) (tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog cov roj corrosive), thiab tseem siv los ua cov khoom siv lubricating rau compressors thiab li qub uas tuaj rau hauv. kev sib cuag nrog cov kua oxygen, oxygen, corrosive thiab oxidizing gases.

6. Kev lag luam Nuclear

Perfluoropolyether yog tsim rau bearing lubrication ntawm ultracentrifuges nyob rau hauv nuclear kev lag luam chaw thiab yog tib yam khoom uas yuav tiv taus uranium hexafluoride corrosion ntawm 130 degree.
