PTFE + MICA MINERAL WEDEDWA

PTFE (PolyTetraFluoroEthylene) ndi polima yopangidwa ndi fluorocarbon yomwe imadziwikanso mumakampani onse ngati dzina lamtundu wa Dupont.polima®.Opanga ena angapo amapanga ma brand awo a PTFE omwe amatha kugwiritsidwa ntchito ngati cholowa m'malo.Banja la fluoroplastic ili limapereka mapulasitiki okhala ndi kukana kwamphamvu kwamankhwala, kutsika komanso kutentha kwambiri, kukana nyengo, kugundana kochepa, kutsekemera kwamagetsi ndi kutentha, komanso "kuterera."

PTFE yodzazidwa ndi 5% mpaka 10% mica imapereka mphamvu yamphamvu komanso kukhazikika kwapadera komanso ukadaulo wapamwamba kwambiri wowonjezera mavalidwe.Chogulitsachi chimapereka kuvala kwabwino komanso kukhazikika kuphatikiza kutsata kwa FDA.

Fluorosint® ndi osakaniza eni ake momwe mica yopangidwa mwaluso imalumikizidwa ndi PTFE.Kulumikizana uku kumabweretsa katundu yemwe sangapezeke mu PTFE yolimbikitsidwa.Magiredi a Fluorosint® amapereka kuphatikiza kwabwino kwa zinthu zotsika kwambiri, kukhazikika kwa mawonekedwe, kukana kwamankhwala, komanso kutentha kosalekeza kwa 500 ° F (260 ° C).Poyerekeza ndi PTFE, ili ndi mphamvu yonyamula katundu wapamwamba, 1/9 ya deformation pansi pa katundu, ndi coefficient yotsika yowonjezera kutentha.

MFUNDO ZA FLUOROSINTFluorosint® 500 ili ndi kukana kopitilira muyeso kasanu ndi kamodzi kuposa PTFE yosadzazidwa.Coefficient yake ya linear thermal expansion (CLTE) imayandikira kukula kwa aluminiyamu ndipo ndi 1/5 ya PTFE - nthawi zambiri imachotsa mavuto oyenerera ndi chilolezo.Ndi 1/3 yolimba kuposa PTFE, ili ndi mawonekedwe ovala bwino, ndipo imasunga katundu wocheperako.Fluorosint ® 500 nayonso sichitha kuwononga zida zambiri zokweretsa.

Fluorosint® 207's kukhazikika kwapang'onopang'ono, kukana kwamphamvu kwambiri komanso mtundu woyera mwapadera imayika izi kuti zigwiritse ntchito zoyendetsedwa ndi FDA.Ndiwosalowetsedwa mu nthunzi ndipo imagwirizana ndi malamulo a FDA 21 CFR 175.300.Mavalidwe ake achibale ndi 1/20 mlingo wa PTFE pansi pa 300°F (150°C).Kuphatikizika kwamakina ochita bwino komanso kukana kwake kwamankhwala ndi hydrolysis, Fluorosint® 207 imatsegula mwayi wambiri wogwiritsa ntchito m'mafakitale azakudya, azachipatala, azachipatala.

APPLICATIONS

• Mapadi amagetsi ndi matenthedwe otsekera pansi pa katundu wophatikizika
• Ma bearings, ma bushings

ZABWINO

• Zabwino kuvala kukana
• Zabwino kwambiri zamakina ndi hydrolysis kukana
• Good mankhwala katundu
• Low coefficient of kukangana
• Kukhazikika kwabwino kwambiri kwazithunzi
• Good magetsi insulating katundu
• Ubwino wa UV komanso kukana kwanyengo
• Chibadwa otsika kuyaka
