PTFE ine yakanakisa yepamusoro uye yakaderera tembiricha kuita, kugadzikana kwemakemikari, kunaka kwemagetsi ekudzivirira, kusanamatira, kusamira kwemamiriro ekunze, kusabatika uye mafuta akanaka.Yakave ichishandiswa muminda yeaerospace kune akawanda ezvigadzirwa zvezuva nezuva, uye yave chinhu chakakosha kugadzirisa akawanda akakosha matekinoroji musainzi yemazuva ano uye tekinoroji, indasitiri yemauto uye kushandiswa kwevanhu.
Kushandiswa mukudzivirira kuonda nekuderedza kupfeka Zvinoenderana nehuwandu hwenyika dzakabudirira, kurasikirwa kwehupfumi kunokonzerwa nekuora kunokwana 4% yehuwandu hwehupfumi hwenyika hunobuda gore rega rega munyika dzanhasi dzakabudirira.Nhamba yakati kuti yetsaona mukugadzirwa kwemakemikari inokonzerwa nekuchinja kwemakemikari kunokonzerwa nekuora kwemidziyo uye kubuda kwepakati.Zvinogona kuonekwa kuti kurasikirwa nekukuvadzwa kunokonzerwa nekuora kwakakomba, izvo zvakamutsa pfungwa huru dzevanhu.
PTFE inokunda kuipa kwemapurasitiki akajairwa, simbi, graphite uye ceramics, senge kusasimba kwekuora uye kuchinjika.Nekunaka kwayo kwepamusoro uye kwakadzika tembiricha kuramba uye kushomeka kwekudzivirira, PTFE inogona kushandiswa mumamiriro ezvinhu akashata senge tembiricha, kudzvanywa uye svikiro, uye yave iyo huru isingadziviriri zvinhu mupetroleum, makemikari, machira uye mamwe maindasitiri.PTFE pombi inonyanya kushandiswa sepombi yekufambisa uye pombi yekupedza gasi rinoparadza, mvura, chiutsi kana makemikari.Iyo yekusundidzira pombi yakagadzirwa nePTFE dispersion resin inoiswa mupombi yesimbi kuti igadzire lining, kana iyo PTFE yekusundidzira pombi yemukati inosimbiswa nemhepo yegirazi fiber, kana iyo PTFE yekusundidzira pombi inosimbiswa nekuruka uye mhepo simbi waya, inogona kufambisa mvura. pakati nepakati pasi pekumanikidzwa kwakanyanya.Sechikamu chakakosha che hydraulic transmission, inogona kuvandudza zvakanyanya simba rekutsemuka pakupisa kwakanyanya uye kuve nekuneta kwekukotama.Nekuti friction coefficient yePTFE material ndiyo yakadzikira pakati pezvinhu zvakasimba zvinozivikanwa, inoita kuti PTFE yakazadzwa ive yakanyatsokodzera mafuta-isina lubrication yemechini michina zvikamu.Semuyenzaniso, midziyo iri muindasitiri yemaindasitiri ekugadzira mapepa, machira, chikafu, nezvimwe zvinosvibiswa nyore nemafuta ekuzora, saka kuzadza PTFE zvinhu kunogadzirisa dambudziko iri.Uye zvakare, kuyedza kunoratidza kuti kuwedzera imwe huwandu hwakasimba hwekuwedzera kuoiri yeinjini kunogona kuchengetedza zvakanyanya 5% yemafuta einjini.
Kumwe kushandiswa kukuru kweiyo corrosion-resistant sealing material PTFE muindasitiri yemakemikari kuisa chisimbiso.Nekuda kwekuita kwayo kwakanaka kuzere, PTFE haienzaniswi kune chero rudzi rwekuisa chisimbiso.Inogona kushandiswa kuisa chisimbiso muzviitiko zvakasiyana-siyana zvakaoma, kunyanya kana tembiricha yakanyanya uye corrosion resistance inodiwa.
Teflon tepi ine faibha refu, simba rakakwirira, yakakwira plastiki uye yakanaka calendability, uye inogona kuvharwa zvachose nekushandisa diki diki.Zviri nyore kushandisa uye kushandisa, uye inoshanda zvakanyanya kana ichishandiswa panzvimbo isina kuenzana kana chaiyo.Iyo ine yakanaka yekuisa chisimbiso kuita, inogona kuvandudza corrosion kuramba uye kuwedzera ayo ekushandisa.PTFE packing inoshandiswa kuvharika kwezvikamu zvinotsvedza, izvo zvinogona kuwana kunaka kwekusagadzikana uye kugadzikana, uye ine kumwe kusimba uye kusimba, uye kushoma kuramba kana kutsvedza.Yakazadzwa PTFE yekuisa chisimbiso ine huwandu hwakasiyana hwekushisa kwekushandisa, inova ndiyo inonyanya kutsiva yechinyakare asbestos gasket zvinhu parizvino.Iyo ine zvakare zvimiro zveyakakwira modulus, yakakwira simba, creep resistance, kuneta kuramba, high thermal conductivity, low coefficient of thermal expansion and friction, etc. Kuwedzera mafiritsi akasiyana-siyana anogona kuwedzera huwandu hwekushandisa.
