Kugwiritsa ntchito mafilimu ang'onoang'ono a PTFE

Makhalidwe a polytetrafluoroethylene
1. Mapangidwe a maselo
2. Kukhazikika kwa mankhwala
3. Thermal katundu
4. Makina katundu
5. Mphamvu zamagetsi
6. Katundu wapamwamba
Kukula kwa filimu ya PTFE microporous
Pakali pano, kupanga ndondomeko yaPTFE microporous filmili ndi njira yosinthira filimu, kutembenuza filimu ndi njira yotambasula.Njira yotambasulira filimu imatha kugawidwa m'njira imodzi komanso yotambasulira njira ziwiri, kudzera mu kusanthula kwamapangidwe ndi kuyeza kwenikweni, filimu yanjira ziwiri zokha imakhala ndi mawonekedwe abwino a microporous.Kapangidwe ka filimu ya PTFE ya biaxially oriented PTFE ikuwonetsedwa pachithunzichi.
Kugwiritsa ntchito filimu ya PTFE microporous
1. Kugwiritsa ntchito muzosefera
2. Kugwiritsa ntchito zinthu zachipatala
Kukonzekera kwa filimu ya PTFE
1. Pre-process ya PTFE microporous film
2. Kukonzekera ndondomeko
3. Njira yopangira
Mphamvu ya magawo ogwiritsira ntchito pazinthu zamakanema a PTFE
Zomwe zimathandizira mphamvu za PTFE mafilimu ang'onoang'ono mu njira yotambasula ya biaxial ndi ndondomeko yake yoyamba ndi yovuta komanso yambiri.Kuwonjezera pa ntchito ya zipangizo processing, kutambasula kutentha ndi kutambasula mlingo, zinthu zina chikoka ndi: ntchito kutentha, ntchito chinyezi.
Kutentha kwa ntchito: Mafilimu a PTFE amakhudzidwa kwambiri ndi kutentha, ndipo kutentha kwapadera kosiyanasiyana kungapangitse zinthu zosiyanasiyana za filimu.Kutentha ndi gawo lofunika kwambiri la ntchito osati pongotambasula, komanso mu PTFE resin processing ndi njira zapakatikati.
Chinyezi Chogwira Ntchito: Chinyezi chimadalira kutentha ndipo sitingakambirane popanda kutentha.Chinyezi chozungulira chimakhudzanso filimuyi.

PTFE ili ndi kukhazikika kwapadera kwamankhwala, kutentha kwambiri komanso kutsika kwa kutentha komanso kukana dzimbiri, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale amankhwala, mafuta, nsalu, zamagetsi ndi zamakina.Panthawiyi, amphamvu hydrophobic ndi porous zimatha PTFE kukhala yabwino nembanemba zakuthupi yokonza madzi ndi mpweya ulusi nsalu komanso nembanemba distillation ndi nembanemba contactors.Poyerekeza ndi zipangizo zina nembanemba, ePTFE nembanemba ndi nembanemba yekha kuti angagwiritsidwe ntchito stably kwa nthawi yaitali ndi mkulu misa kutengerapo coefficient, ndi ubwino waing'ono, amphamvu kudzithandiza luso ndi mkulu Kachulukidwe kachulukidwe za dzenje CHIKWANGWANI nembanemba kupanga PTFE dzenje CHIKWANGWANI CHIKWANGWANI nembanemba amakopa chidwi kwambiri m'munda wa nembanemba contactors.
Porous PTFE dzenje CHIKWANGWANI nembanemba amakonzedwa ndi extrusion-chojambula njira, ndi ndondomeko kukonzekera kumaphatikizapo kusakaniza, extrusion kupota, unidirectional kutambasula ndi sintering.Zosakaniza zonse za PTFE zimakanikizidwa pa chosindikizira chopanda kanthu kuti cylindrical ikhale yopanda kanthu.Zolemba zomwe zidasindikizidwa kale zimatulutsidwa ndikuzungulira pa 40-100 ° C.Pambuyo degreasing, kutentha-kukhazikitsa kupeza PTFE dzenje CHIKWANGWANI nembanemba.Kutentha kwa kutentha ndi 200-340 ° C, kutentha kwa kutentha ndi 330-400 ° C, ndi nthawi yotentha ndi 45-500 s.Mawonekedwe ang'onoang'ono ndi ozungulira (ozungulira kapena ozungulira) pore.
