Chisindikizo cha mafuta cha PTFE cholimba komanso cholimba
Ubwino wa chisindikizo cha mafuta cha PTFE
1. Kukhazikika kwa mankhwala: pafupifupi mankhwala onse okana, asidi wamphamvu, maziko olimba kapena okosijeni amphamvu ndi zosungunulira zachilengedwe sizimakhudzidwa.
2. Kukhazikika kwa kutentha: kutentha kwa ming'alu kuli pamwamba pa 400℃, kotero kumatha kugwira ntchito bwino pamtunda wa -200℃350℃.
3 kukana kuvala: PTFE zinthu friction coefficient ndi yochepa, 0.02 yokha, ndi 1/40 ya rabara.
4. Kudzipaka mafuta: Zipangizo za PTFE zili ndi ntchito yabwino kwambiri yodzipaka mafuta, pafupifupi zinthu zonse zokhuthala sizingamamatire pamwamba.
Kodi ubwino wa chisindikizo cha mafuta cha PTFE ndi wotani poyerekeza ndi chisindikizo cha mafuta wamba a rabara?
1. Chisindikizo cha mafuta cha Ptfe chapangidwa ndi milomo yayikulu popanda kasupe, chomwe chingagwire ntchito bwino nthawi zambiri pantchito;
2. Pamene shaft izungulira, imapanga yokha kupondereza mkati (kupanikizika kumakhala kwakukulu kuposa chisindikizo cha mafuta a rabara wamba), zomwe zingalepheretse kuyenda kwa madzi;
3. Chisindikizo cha mafuta cha Ptfe chingakhale choyenera malo ogwirira ntchito opanda mafuta kapena mafuta ochepa, makhalidwe otsika a kukangana pambuyo potseka, poyerekeza ndi chisindikizo cha mafuta wamba cha mphira chomwe chimagwiritsidwa ntchito kwambiri;
4. Zisindikizo za Ptfe zimatha kutseka madzi, asidi, alkali, zosungunulira, mpweya, ndi zina zotero;
5. Chisindikizo cha mafuta cha PTFE chingagwiritsidwe ntchito kutentha kwakukulu kwa 350℃;
6. Chisindikizo cha mafuta cha PTFE chimatha kupirira kuthamanga kwambiri, chimatha kufika 0.6 ~ 2MPa, ndipo chimatha kupirira kutentha kwambiri komanso liwiro lalikulu.
Kugwiritsa ntchito
zokumba, injini, zida zamakina aukadaulo, mapampu otulutsa utsi, nyundo zophwanya, zida zamankhwala ndi akatswiri osiyanasiyana, zidazi ndizoyenera makamaka chisindikizo cha mafuta a rabara chachikhalidwe chomwe sichingakwaniritse ntchito.
