Chithunzi cha PTFE

Ndodo ya PTFE ndi utomoni wosadzazidwa wa PTFE woyenera pokonza ma gaskets osiyanasiyana, zosindikizira ndi zopaka mafuta zomwe zimagwira ntchito pazida zowononga, komanso zida zotchingira magetsi zomwe zimagwiritsidwa ntchito pama frequency osiyanasiyana. (Ikhoza kukhala ndi ndodo zobwezerezedwanso za polytetrafluoroethylene) zopangidwa ndi kuumba, phala extrusion kapena plunger extrusion process.

khalidwe

Kutentha kogwira ntchito ndi kwakukulu kwambiri (kuchokera -200 madigiri mpaka +260 madigiri Celsius).

Kwenikweni, ili ndi kukana kwa dzimbiri kuzinthu zonse zamankhwala kupatula ma fluoride ndi zakumwa zamchere zamchere.

Zinthu zabwino zamakina zimaphatikizira kukana kukalamba, makamaka pakupinda ndi kugwedezeka.

Kubwezeretsanso kwabwino kwa lawi (molingana ndi njira zoyeserera za ASTM-D635 ndi D470, zimasankhidwa ngati chinthu choyaka moto mlengalenga.

Zabwino kwambiri zotchinjiriza (mosasamala za kuchuluka kwake ndi kutentha kwake)

Mayamwidwe amadzi ndi otsika kwambiri, ndipo ali ndi mndandanda wazinthu zapadera monga kudzilimbitsa komanso kusamamatira.

ntchito

Pali mitundu iwiri ya ndodo za PTFE: ndodo zokankhira ndi ndodo zoumbidwa. Pakati pa mapulasitiki odziwika, PTFE ili ndi katundu wabwino kwambiri.

Kukana kwake kwamankhwala ndi zida za dielectric zitha kugwiritsidwa ntchito kutentha kwa -180 ℃－+260 ℃, ndipo imakhala ndi coefficient yotsika kwambiri. Ndizoyenera kwambiri pazinthu zina zazitali komanso zosagwirizana ndi makina: zisindikizo / ma gaskets, zida za mphete, mbale / mipando yosamva kuvala, zida zotetezera, mafakitale odana ndi dzimbiri, zida zamakina, zomangira, mafuta ndi gasi, mafakitale a petrochemical, mafakitale opanga mankhwala, opanga zida ndi zida, etc.

Ntchito yogwiritsira ntchito ndodo ya PTFE

Makampani a Chemical: Atha kugwiritsidwa ntchito ngati zinthu zotsutsana ndi dzimbiri, ndipo angagwiritsidwe ntchito popanga zida zosiyanasiyana zolimbana ndi dzimbiri, monga mapaipi, mavavu, mapampu ndi zida zapaipi. Pazida zamagetsi, zotchingira ndi zokutira za ma reactors, nsanja za distillation ndi zida zothana ndi dzimbiri zitha kupangidwa.

Mbali yamakina: Itha kugwiritsidwa ntchito ngati mayendedwe odzipangira okha, mphete za pistoni, zisindikizo zamafuta ndi mphete zomata, etc. Kudzipaka mafuta kumatha kuchepetsa kuvala ndi kutentha kwa magawo amakina ndikuchepetsa kugwiritsa ntchito mphamvu.

Zipangizo zamagetsi: zomwe zimagwiritsidwa ntchito makamaka popanga mawaya ndi zingwe zosiyanasiyana, maelekitirodi a batri, zolekanitsa batire, matabwa osindikizidwa, etc.

Zipangizo zachipatala: Pogwiritsa ntchito mphamvu zake zosatentha, zosagwira madzi, komanso zopanda poizoni, zimatha kugwiritsidwa ntchito ngati zipangizo zosiyanasiyana zamankhwala ndi ziwalo zopangira. Zoyambazo zimaphatikizapo zosefera zosabala, zikho, ndi zida zapamtima zopanga kupanga, pomwe zomalizirazo zimaphatikizapo mitsempha yamagazi, mtima, ndi khosi. Zakhala zikugwiritsidwa ntchito kwambiri ngati chinthu chosindikizira komanso chodzaza.
