Mhando dzese dzezvigadzirwa zvePTFE dzakaita basa rakakosha munzvimbo dzehupfumi hwenyika senge indasitiri yemakemikari, michina, zvemagetsi, midziyo yemagetsi, indasitiri yemauto, ndege, kuchengetedza kwezvakatipoteredza uye mabhiriji.
Tetrafluoroethylene board inokodzera tembiricha ye -180 ℃ ~ + 250 ℃.Inonyanya kushandiswa semagetsi ekudzivirira zvinhu uye linings yekusangana neyakaora midhiya, inotsigira masiraidhi, zvisimbiso zvenjanji uye zvinhu zvekuzora.Inoshandiswa muindasitiri yakareruka nehupfumi kabati fenicha., Inoshandiswa zvakanyanya mumakemikari, mishonga, dhayi indasitiri midziyo, matangi ekuchengetedza, reaction tower kettles, anti-corrosion lining zvinhu zvemapaipi makuru;zvendege, zvechiuto uye mamwe maindasitiri anorema;michina, kuvaka, traffic bhiriji anotsvedza, njanji;kudhinda uye kudhaya, indasitiri yemwenje, machira Indasitiri inorwisa-kunamatira zvinhu, nezvimwe.
Zvinhu zvakanakira zvinhu
High tembiricha kuramba - tembiricha kushanda inogona kusvika 250 ° C.
Kudzikira kwakadzika kwekushisa - kune kusimba kwakanaka kwemagetsi;kunyangwe tembiricha ikadonha kusvika -196 ° C, inogona kuchengetedza kurebesa kwe5%.
Corrosion resistance - inert kune akawanda makemikari uye zvinonyungudutsa, zvinopesana neakasimba acids uye alkalis, mvura uye akasiyana organic solvents.
Weather resistant - ine hupenyu hwekuchembera hwakanakisa pakati pemapurasitiki.
High lubrication - iyo yakaderera coefficient of friction pakati pezvinhu zvakasimba.
Kusina-kunamatira - idiki diki tension pakati pezvinhu zvakasimba, hainamati kune chero chinhu, uye mashandiro ayo emagetsi ane diki diki friction coefficient, inova 1/5 chete ye polyethylene, inova chinhu chakakosha cheperfluorocarbon. surfaces.Uye nekuda kweiyo yakanyanya kuderera intermolecular simba refluorine-kabhoni cheni, PTFE haina kunamira.
Isiri-chepfu - haina physiologically inert uye haina maitiro akashata kana yaiswa mumuviri setsinga yeropa uye nhengo kwenguva yakareba.
Magetsi zvivakwa PTFE ine yakaderera dielectric inogara uye dielectric kurasikirwa muhupamhi frequency renji, uye yakakwirira breakdown voltage, vhoriyamu resistivity uye arc kuramba.
Radiation resistance Kupokana nemwaranzi yepolytetrafluoroethylene kwakashata (104 rads), uye kunoderedzwa nemwaranzi ine simba guru, uye magetsi nemagetsi epolymer akadzikira zvakanyanya.Kushandisa PTFE kunogona kugadziriswa nekumanikidza kana extrusion;inogona zvakare kugadzirwa kuita aqueous dispersion yekuputira, kupfekedza kana kugadzira mafibhi.PTFE inoshandiswa zvakanyanya seyakakwira uye yakaderera tembiricha inodzivirira, corrosion resistant materials, insulating materials, anti-stick coatings, nezvimwewo muatomu simba, aerospace, zvemagetsi, magetsi, makemikari, michina, zviridzwa, mita, kuvaka, machira, chikafu nezvimwe. maindasitiri.
Atmospheric kuchembera kuramba: kurwisa kwemwaranzi uye kuderera kwepasi: kuratidzwa kwenguva refu kumhepo, pamusoro uye kushanda zvinoramba zvisingachinji.
Kusina-kupisa: Iyo inomisa oksijeni index iri pazasi 90.
Acid uye alkali kuramba: isinganyunguriki muasidhi yakasimba, yakasimba alkali uye organic solvent.
Oxidation kuramba: Inogona kuramba kukora kweakasimba oxidants.
Acidity uye alkalinity: kusarerekera.
Iyo mechanic properties yePTFE yakapfava.Iine simba repamusoro rakaderera.
Polytetrafluoroethylene (F4, PTFE) ine mutsara wekuita kwakanakisisa: kukwirira kwekushisa kwepamusoro - kushandiswa kwenguva refu tembiricha 200 ~ 260 madhigirii, kuderera kwekushisa kwekudzivirira - kuchiri kupfava pa -100 degrees;corrosion resistance - kuramba kune aqua regia uye zvose organic solvents;Kuramba kwemamiriro ekunze-hupenyu hwakanakisa hwekukwegura pakati pemapurasitiki;high lubricity-diki diki coefficient of friction (0.04) pakati pepurasitiki;non-stick-kunyanya kuderera kwepamusoro pakati pezvinhu zvakasimba pasina kunamatira kune chero chinhu;isiri-chepfu-physiologically inert;Yakanakisa magetsi zvivakwa, yakanakira Kirasi C insulating zvinhu.
