Kupokana kwakaderera uye kushomeka kwemagetsi mashandisiro ndiwo mabhenefiti anopihwa nePTFE zvisimbiso.Izvi zvisimbiso zvinogona kushandiswa pasina matambudziko zvakare nekuoma ...
Pasinei nemhando dzayo dzinoshamisa dzakachena, dzisina kuzadzwa kana mhandara PTFE haina kukwana kune imwe nhamba yakawanda inoda mainjiniya application.Kunyanya, kutonhora kwayo kuyerera kana hunhu hwezvinokambaira hwairambidza kushandiswa kwePTFE mumashini ekushandisa.Kunyangwe pakupisa kwekamuri, PTFE inosangana nekushanduka kwakakosha nekufamba kwenguva kana ichiiswa pamutoro unoramba uripo.Uyezve, mhandara yePTFE haina kana kusimba uye inopfeka nekukurumidza kunyangwe yakaderera coefficient of friction.Mumakore ekuma1960, kuwedzera kwekuzadza kwakawanikwa kunatsiridza huwandu hwezvinhu zvemuviri, kunyanya zvinokambaira uye chiyero chekupfeka.Mazhinji mafiritsi akatsiga kusvika ku400 °C, saka haarambidze kushandiswa mukupisa kwakanyanya.Zvakanyorwa pazasi ndezvimwe zvakajairika mafirita uye maitiro azvo pane zvepanyama zvePTFE komboni.
Girazi fiber
Girazi faibha chinhu chinowanzo shandiswa kuzadza chinhu chine hunhu hwakanaka pazvinokambaira kuita kwePTFE, iyo inodzikiswa pane yakaderera uye yakakwirira tembiricha.Iyo inowedzerawo kupfeka kuramba uye inopa yakanaka compression simba.Ichi chinowedzerwa chine makemikari inert kunze kwekuvapo kwehydrofluoric acid uye mabhesi akasimba.Iine zvishoma zvishoma pamagetsi emagetsi.
Carbon uye carbon-graphite
Carbon inoderedza kukambaira, inowedzera kuomarara uye inosimudzira kudziya kwePTFE.Kupfeka kuramba kwekabhoni yakazadzwa makomisheni inovandudza kunyanya mukubatana negraphite.Carbon ndeimwe yeanonyanya kupinza mafiritsi kunze kwekunge mune oxidizing nharaunda umo girazi rinoita zvirinani.Carbon inopa mamwe magetsi conductivity kuPTFE.PTFE yakazadzwa nekabhoni ndiyo inowanzo shandiswa pakuisa chisimbiso chepneumatic. Misanganiswa ine kabhoni yakasanganiswa negraphite ndizvo zvinofarirwa zvekushandisa zvisina mafuta.
Carbon fiber
Kuwedzerwa kwekabhoni fiber kuPTFE inoshandura zvimiro zvayo nenzira imwechete segirazi fiber inoita.Iyo inoderedza zvinokambaira, inowedzera flex uye compressive modulus uye inosimudza kuoma.Kakawanda, kabhoni kabhoni fiber inodiwa kuti iite zvakafanana.Iyo coefficient yekuwedzera kwekushisa inoderedzwa uye thermal conductivity yakakwira kune makomisheni ecarbon fiber akazadzwa PTFE.Kupfeka kunodzikira kana maparts ecarbon faibha aiswa mvura.Carbon faibha inekemikari inert uye inogona kushandiswa mumabhesi akasimba uye hydrofluoric acid.
Graphite
Graphite is crystalline modification yepamusoro-kuchena kabhoni.Graphite yakazadzwa PTFE ine imwe yeakaderera coefficients yekukwesha nekuda kweiyo yakaderera friction maitiro egraphite.Iyo ine yakanakisa kupfeka zvivakwa, kunyanya inopesana neyakapfava mating nzvimbo uye inoratidza yakakwirira-yekutakura-yekutakura kugona mune yakakwirira-kumhanya yekubata maapplication.Graphite ikemikari inert inogonesa kushandiswa kwayo mune zvinoparadza media.
Bronze
Bronze ndeye yakajairika metallic filler.Huru huwandu (40 kusvika 60 % nehuremu) hwebhuronzi inoderedza deformation pasi pemutoro uye inosimudza kupisa uye magetsi conductivity yePTFE makomponi.Aya maitiro maviri anobatsira kune zvikumbiro apo chikamu chinoiswa pasi pekupisa zvakanyanya.Bronze yakazadzwa PTFE inopa yakanakisa extrusion kuramba maitiro.Bronze ialloy yemhangura netin uye inogona kurwiswa nemamwe makemikari.Oxidation yebhuronzi inogona kukonzera kudzima kwechikamu chakapedzwa pasina kukanganisa kunaka kwechigadzirwa.PTFE yakazadzwa nebhuronzi inoshandiswa zvakanyanya mu hydraulic rod uye piston seal application.
Molybdenum disulfide (MoS2)
Molybdenum disulphide inowedzera kuoma uye kuomarara kwePTFE uku ichideredza kupokana.Iine zvishoma zvishoma pamagetsi ayo emagetsi.Chemically, inonyanya kusagadzirisa uye inonyunguduka chete mune yakasimba oxidizing acids.Inowanzoshandiswa muzvikamu zviduku zvehuremu uye pamwe chete nemamwe mafiritsi akadai segirazi fiber.
Inonhuhwirira polyester
Polyester inonhuhwirira sechinhu chinozadza inosimudza tembiricha yepamusoro yePTFE uye yakanakira kushandiswa nenzvimbo dzakapfava, dzine simba.
Mavara ekuwedzera
Zvinogoneka kuisa pigment PTFE nekushandisa inorganic color additives inoshingirira tembiricha yekupisa yePTFE.Pigments haishandure zvakanyanya zvinhu zvePTFE.Musanganiswa we pigment uye mamwe mafiller anogoneka.Proprietary fillers uye filler musanganiswaParker arikuramba achiedza kutsvaga nekugadzira akasiyana masanganiswa uye maumbirwo ekuwedzera kuvharisa kuita mukunyanya kunyorera.
