Kutentha kwakukulu & kuvala kugonjetsedwa kwa mafuta a PTFE
Ubwino wa PTFE mafuta chisindikizo
1. Kukhazikika kwa mankhwala: pafupifupi kukana kwa mankhwala, asidi amphamvu, maziko amphamvu kapena oxidant amphamvu ndi organic solvents sakhudzidwa.
2. Kukhazikika kwamafuta: kutentha kwapang'onopang'ono kuli pamwamba pa 400 ℃, kotero kumatha kugwira ntchito mosiyanasiyana -200 ℃350 ℃.
3 kuvala kukana: PTFE zinthu kukangana coefficient ndi otsika, 0.02 yekha, ndi 1/40 wa mphira.
4. Kudzipaka mafuta: PTFE zakuthupi ali kwambiri kudzikonda kondomu ntchito, pafupifupi onse viscous zinthu sangathe kutsatira pamwamba.
Kodi ubwino wa PTFE mafuta chisindikizo poyerekeza ndi wamba mphira chisindikizo mafuta?
1. Ptfe mafuta chisindikizo lakonzedwa ndi lonse milomo mphamvu popanda kasupe, amene angathe kugwira ntchito bwinobwino pansi kwambiri mikhalidwe ntchito;
2. Shaft ikazungulira, imangopanga kulowera mkati (kupanikizika kumakhala kopitilira muyeso wamba wamafuta), zomwe zimatha kuletsa kutuluka kwamadzi;
3. Ptfe mafuta chisindikizo akhoza kukhala oyenera palibe mafuta kapena zochepa mafuta malo ntchito, otsika mikangano makhalidwe pambuyo shutdown, poyerekeza ndi wamba mphira chisindikizo chamafuta chimagwiritsidwa ntchito kwambiri;
4. Zisindikizo za Ptfe zimatha kusindikiza madzi, asidi, alkali, zosungunulira, mpweya, ndi zina zotero;
5.PTFE mafuta chisindikizo angagwiritsidwe ntchito pa kutentha apamwamba 350 ℃;
6. PTFE mafuta chisindikizo akhoza kupirira kuthamanga kwambiri, akhoza kufika 0.6 ~ 2MPa, ndipo akhoza kupirira kutentha ndi liwiro.
Kugwiritsa ntchito
ofukula, injini, zida zamakina opangira makina, mapampu a vacuum, nyundo zophwanyidwa, zida zochizira mankhwala ndi akatswiri osiyanasiyana, zidazo ndizoyenera kwambiri chisindikizo chamafuta cha rabara sichingakwaniritse ntchito.
