Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer ye tetrafluoroethylene ine akawanda maapplication.Zita rinonyanya kuzivikanwa remhando yePTFE-based…
PolyTetraFluoroEthylene ifluorocarbon-based polymer uye inowanzodimburirwa PTFE.Vamwe vagadziri vakati wandei vanogadzira yavo mabhureki ePTFE ayo anogona kazhinji kushandiswa seanotsiva zvinhu.Iyi mhuri yefluoroplastic inopa yakakwira makemikari kuramba, yakaderera uye yakakwirira tembiricha kugona, kuramba kumamiriro ekunze, kutsika kwakadzika, magetsi uye kupisa kwemafuta, uye "kutsvedza".( onawo polymer® PTFE uyepolymer® FEP & PFA Specifications ) PTFE's mechanical properties ishoma kana ichienzaniswa nemamwe mapurasitiki, asi zvimiro zvayo zvinoramba zviri pamwero unobatsira pamusoro petembiricha yakawanda ye -100 ° F kusvika +400 ° F (-73 ° C kusvika 204 ° C) .Mechanical properties inowanzo wedzerwa nekuwedzera mafirita (ona ndima pazasi).Iyo ine yakanakisa kupisa uye magetsi ekudzivirira zvivakwa uye yakaderera coefficient yekukwesha.PTFE yakakora kwazvo uye haigone kunyungudutswa - inofanirwa kudzvanywa nekunyungudutswa kuti iumbe zvimiro zvinobatsira.
PTFE's mechanical properties inogona kukwidziridzwa nekuwedzera mafirita akadai segirazi fibers, kabhoni, graphite, molybdenum disulphide, uye bhuronzi.Kazhinji, yakazadzwa PTFE inochengetedza yakanakisa kemikari uye yakakwirira tembiricha maitiro, nepo mafirita achivandudza simba remuchina, kugadzikana, uye kupfeka kuramba.Zvimiro zve25% girazi-yakazadzwa uye 25% kabhoni-yakazadzwa PTFE mamakisi anoratidzwa pazasi nekuda kwekuenzanisa.Kune akawanda chaiwo akasiyana akazadzwa zvigadzirwa zvePTFE uye mamakisi - zvakawandisa kuti zvinyorwe pano.
TYPICAL PROPERTIES yePTFE
CHERECHEDZA: Ruzivo rwuri pano nderwetsika dzakagadzirirwa kutariswa uye kuenzanisa zvinangwa chete.HAZVIFANIRE kushandiswa sehwaro hwemagadzirirwo ezvakatemwa kana kudzora kwemhando.Bata isu kune vagadziri vakazara zvinhu zvivakwa datasheets.Zvose zvakakosha pa 73°F (23°C) kunze kwekunge zvaitwa.
