Material zvakwakanakira PTFE bhodhi

Yakakwira tembiricha kuramba-iyo inoshanda tembiricha inogona kusvika 250 ℃.

Yakadzika tembiricha kuramba-ine yakanaka michina kuomarara; kunyangwe iyo tembiricha ikadzika kusvika -196 ℃, inogona kuchengetedza 5% kukwirisa.

Corrosion kuramba-Iyo inert kune mazhinji makemikari uye solvents, uye inogona kumira yakasimba acids uye alkalis, mvura uye akasiyana organic manyoro.

Mamiriro ekunze kusagadzikana-ane akanakisa hupenyu hwechembere pakati pemapurasitiki.

Yakanakisa lubrication-ndiyo yakaderera coefficient yekukwesana pakati pezvakasimba zvinhu.

Isiri-yekunamatira – ndiyo diki diki yepasi kukakavara pakati pezvakasimba zvinhu uye haina kuomerera kune chero chinhu. Iko kukanganiswa kwekukwikwidzana kwema mechanical zvimiro zvidiki zvakanyanya, chete 1/5 yeiyo ye polyethylene, chinova chinhu chakakosha che perfluorocarbon pamusoro. Uye zvakare, nekuti iyo fluorine-kabhoni ketani yemamolecular mauto yakaderera zvakanyanya, PTFE haina-kunamira.

Isina-chepfu-Iyo physiologically inert uye haina maitiro akashata semidziyo yeropa yekuisira uye nhengo dzakaisirwa mumuviri kwenguva yakareba.

Magetsi zvivakwa Polytetrafluoroethylene ine yakaderera dielectric inogara uye dielectric kurasikirwa mune yakafara frequency renji, uye ine yakanyanya kuputsika magetsi, vhoriyamu resistivity uye arc kuramba.

Radiation kuramba Polytetrafluoroethylene ine murombo radiation radiation (104 rad), uye inoshoreka mushure mekuratidzwa kune yakakwira-simba radiation, uye emagetsi uye mechimiro zvimiro zveiyo polymer zvakaderedzwa zvakanyanya. Kunyorera Polytetrafluoroethylene inogona kuumbwa nekumanikidza kana extrusion kugadzirisa; inogona zvakare kuitwa mukupararira kwemvura kwekumhara, kunyudza kana kugadzira tambo. Polytetrafluoroethylene inoshandiswa zvakanyanya senge yakakwira uye yakadzika tembiricha inodzivirira, ngura inodzivirira zvinhu, inodzivirira zvinhu, anti-kunamatira machira, nezvimwe musimba renyukireya, muchadenga, zvemagetsi, zvemagetsi, zvemagetsi, zvemakemikari, michina, zviridzwa, metres, kuvaka, machira, chikafu uye zvimwe maindasitiri.

Atmospheric kukwegura kuramba: radiation radiation uye yakaderera kukwana: kuratidzwa kwenguva refu kumhepo, pamusoro uye mashandiro zvinoramba zvisina kuchinja.

Isinga-batsike: Iyo oxygen muganho indekisi iri pazasi pe90.

Acid uye alkali kuramba: insoluble mune yakasimba acids, yakasimba alkalis uye organic solvents.

Oxidation resistance: inopesana nekuora neakasimba maokisi.

Acidity: Kwazvakarerekera.

Iko michina maficha ePTFE akapfava. Iine yakaderera kwazvo nzvimbo simba.

Polytetrafluoroethylene (F4, PTFE) ine nhevedzano yekuita kwakanakisa: kupisa kwakawanda kupisa-kwenguva-refu tembiricha yekushandisa ye200 ~ 260 degrees, yakaderera tembiricha kuramba-ichiri yakapfava pa -100 madigiri; ngura kuramba-kurwisa kune aqua regia uye ese manyoro solvents; Mamiriro ekunze kuramba – hupenyu hwakanakisa hwekukwegura mumapurasitiki; yakakwira lubrication-iine coefficient diki yekukwesana (0.04) mumapurasitiki; isina-kuomerera-ine diki diki yekunetsana mune yakasimba zvinhu pasina kunamatira kwechinhu chero chipi zvacho; non-chepfu-pamwe vasiri inertness; Yakanaka magetsi emagetsi, iri yakanaka C-kirasi inodzivirira zvinhu.
