Kune marudzi maviri ePTFE mahwendefa: kuumba uye skiving / kutendeuka.Iyo ndiro yekuumba inogadzirwa ne polytetrafluoroethylene resin nekuumba pane tembiricha yekamuri, uye yobva yanyungudutswa nekutonhodzwa.Iyo inotendeuka ndiro inogadzirwa nePTFE resin nekutsikirira, sintering, uye kupepeta.

PTFE ndiro ine yakanakisa abrasion kuramba pakati peeinjiniya mapurasitiki uye ndiyo inonyanya kubata maziso.Kukwirisa huremu hwemamorekuru, ndiko kunowedzera kusapfeka zvinhu, kutopfuura zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo).Semuenzaniso, mapaipi eUHMW-pe ane hupenyu hwebasa re4-6 nguva dzemapombi esimbi pasi pemamiriro ekuora kwakasimba uye kupfeka kwakanyanya, uye kushanda kwekufambisa kunowedzera ne20%.Inonyatsoratidza hukuru hwe "kuchengetedza simba, kuchengetedza kwezvakatipoteredza, hupfumi, uye kushanda kwakanyanya".
Ndezvipi zvakanakira PTFE ndiro?
High-tembiricha kuramba- Kushanda tembiricha inogona kusvika 250 ℃.
Kuderera-kupisa kupikisa- Iine yakanaka mechanic kuoma;kunyangwe tembiricha ikadonha kusvika -196 ℃, inogona kuchengetedza 5% kureba.
Corrosion resistance- Iyo inert kune akawanda makemikari uye zvinonyungudutsa, uye inogona kumira yakasimba asidhi uye alkalis, mvura uye akasiyana organic solvents.
Kuramba kwemamiriro ekunze-Ane hupenyu hwekuchembera hwakanakisa pakati pemapurasitiki.
High lubrication-Iyo yakaderera coefficient yekukwesha pakati pezvinhu zvakasimba.
Kusina-kunamatira-Iyo idiki diki tension pakati pezvinhu zvakasimba uye hainamati kune chero chinhu.Iko friction coefficient ye mechanical properties iduku zvikuru, 1/5 chete ye polyethylene, iyo inokosha inokosha yeperfluorocarbon surface.Pamusoro pezvo, nekuti iyo fluorine-kabhoni cheni intermolecular masimba akadzikira zvakanyanya, PTFE haina kunamira.
Kwete-chepfu-Ne physiological inertness, kuisirwa kwenguva refu kwemidziyo yeropa uye nhengo dzemuviri mumuviri pasina kuita kwakashata.
Iyo yekushandiswa kwemhando yePTFE ndiro yakaita seinotevera:
1. Ichishandisa maitiro eiyo yakaderera friction coefficient, inoshandiswa kune offshore mafuta kuchera derrick slide veneer, dock slide veneer, river dam gedhi redhiraidhi, bhiriji telescopic rutsigiro slide veneer, akasiyana muchina maturusi, machina anofinha, Grinder, planer inotsvedza gidhi. , nezvimwewo.
2. Ichishandisa zvimiro zvayo zvisina tsvimbo, inoshandiswa muindasitiri yeshuga, indasitiri yezvipfeko, chikafu, uye bhandi rekutakura fodya yekubikira, kudhinda, uye dhayi indasitiri anti-sticking anti-corrosion coating layer yeakasiyana gidhi rollers, nezvimwe.
3. Kushandiswa kwemagetsi emagetsi ane maitiro akanaka uye anoshandiswa mumagetsi ekupisa, masero e electrolytic, zvindori zvekuisa chisimbiso, madhigirii akadhindwa mumagetsi emagetsi uye makombiyuta emagetsi emagetsi emagetsi, mhangura-clad substrates, zvakasiyana-siyana zvekucheka uye zvigadzirwa zvemichina yakakosha.
4. Kutora mukana wekugadzikana kwayo kwekemikari yakanaka, inogona kunyanya kushandiswa kune gaskets, linings, valve discs, uye diaphragms yemavharuvhu makuru mupetroleum, makemikari, uye maindasitiri emakemikari, pamwe nemaraini ezvikepe zvakasiyana-siyana zvinosangana, matangi ekuchengetedza. , uye reaction tower, ndiro yekugovera, nezvimwe.
Kushandiswa kwekagadziridzwa PTFE ndiro
Yakashandurwa PTFE ndirondiyo inosarudzirwa yekugadzira-inodzivirira lining, saka ndedzipi nzvimbo dzekushandisa dzeiyo yakagadziridzwa PTFE ndiro?
Sechinhu chekuisa chisimbiso, mahwendefa ePTFE akagadziridzwa anoshandiswa zvakanyanya mumichina, petrochemical, zvekufambisa, machira, uye maindasitiri ekuvaka.Zvinoenderana neyakasarurwa gasi permeability yePTFE ndiro mushure mekurapwa, inogona kushandiswa sechinhu chekuparadzanisa kuti isarudze kupinza gasi kana mvura, kunyanya kusefa zvinwiwa zvinoparadza.Mumakore achangopfuura, iyo yakagadziridzwa PTFE ndiro yakashandiswa senhengo yakagadzirwa, uye ichashandiswa kune zvakasiyana-siyana mune ramangwana, iyo ine tarisiro yakanaka yekusimudzira.
