Perfluoropolyethers thiab cyclic tripolyphosphazene tau cog lus tias yav tom ntej aviation cav roj

CovCov qauv molecular ntawm Perfluoropolyethers (Perfluoropolyethers, abbreviated li PFPE) lubricants yog ib txwm zoo ib yam li cov hydrocarbon lubricants, tab sis nyob rau hauv PFPE molecules, fluorine atoms hloov hydrogen atoms, yog li hloov cov c-H bonds nyob rau hauv hydrocarbons uas muaj zog c-F bonds. Thiab lub xub ntiag ntawm c-o thiab c-c muaj zog covalent bonds, nrog rau cov yam ntxwv nruab nrab ntawm PFPE molecules, ua rau PFPE muaj thermal stability thiab oxidation stability, nrog rau cov tshuaj zoo inertness thiab insulating zog. PFPE nrog qhov hnyav dua molecular kuj muaj qhov tsis muaj zog, qhov dav ntawm cov kua dej ntau thiab cov yam ntxwv zoo viscosity-kub. Tsis tas li ntawd, cov khoom tseem ceeb ntawm lub cev thiab tshuaj lom neeg ntawm PFPE polymers suav nrog: kev tshawb pom kev ruaj ntseg, kev lom neeg tsis muaj zog, tsis tshua muaj zog saum npoo, zoo lubrication thiab compatibility nrog plastics, hlau thiab khoom siv roj hmab.

Daim ntawv thov teb PEPF perfluoropolyether roj tuaj yeem ua tau raws li daim ntawv thov ntawm qhov kub thiab txias hauv kev lag luam thiab kev lag luam tsheb. Kev ruaj ntseg siab thiab muaj peev xwm tiv thaiv hnav zoo ua rau PEPF perfluoropolyether roj haum rau kev ua haujlwm ntev thiab kev ua haujlwm hnyav Lubricants raws li nram no:

Kev lag luam tshuaj:PEPF perfluoropolyether roj yog siv los ua cov kua dej ua haujlwm hauv ntau lub tshuab nqus tsev twj (rotary twj, turbomolecular twj thiab vapor diffusion twj); muaj corrosive gases (xws li: kua oxygen thiab pa oxygen, halogen, sulfur) nyob rau hauv lub chaw ua hauj lwm Crisp, thiab lwm yam) muaj, PEPF perfluoropolyether roj yog siv los ua lubricating roj rau compressors thiab li qub.

Electronics kev lag luam:Qee lub tshuab nqus tsev twj siv rau hauv kev tsim cov semiconductors los ntawm kev siv plasma etching, LPCVD thiab plasma implantation technologies, thiab PEPF perfluoropolyether roj yog siv los ua cov roj lubricating rau lub tshuab nqus tsev twj kom ua tiav cov txiaj ntsig zoo;

Mechanical kev lag luam:PEPF perfluoropolyether roj feem ntau yog siv los ua kub thiab tshuaj lom neeg ruaj khov porous hlau bearing conveyor siv, papermaking thiab textile machinery lubricants, thaum siv los ua yas bearing lubricants, nws muaj peev xwm los tiv thaiv hnav tau zoo heev, thaum qee cov khoom siv electromechanical PFPE lubricating roj feem ntau siv. thaum zoo lubrication thiab arc kuj yuav tsum tau (xws li tam sim no contactors, hloov khawm thiab zawv zawg hluav taws xob contactors, thiab lwm yam);

Aerospace kev lag luam:Vim tias PEPF perfluoropolyether roj muaj cov kua kub ntau, tsis tshua muaj evaporation, siab zoo li qub viscosity, tsis tshua muaj vapor siab, tsis tshua muaj siab kub thiab zoo siab lubricity, nws tau dav siv nyob rau hauv aerospace kev lag luam daim ntawv thov;

Magnetic media kev lag luam: Tsis tshua muaj kev sib txhuam coefficient, tsis tshua muaj hluav taws xob thiab zoo rwb thaiv tsev ua rau PFPE tuaj yeem siv rau lubrication ntawm hard disks, tapes thiab lwm yam sib nqus cov ntaub ntawv xov xwm hauv computer, video kaw, tsis siv neeg kaw cov cuab yeej thiab lwm yam twj paj nruag;
