PTFE gasket

PTFE gaskets ane akanakisa zvimiro zvekukambaira kuramba, kutonhora kuyerera kuramba, Ultra-yakaderera tembiricha kuramba, hapana kusvibiswa, uye nyore kugadzika uye disassembly. Pasi pesimba diki risati rasimba, rinogona kumirisana nekumanikidza kwemukati kunyangwe mumamiriro ekuchinja-chinja. Yakanyatsokodzera kune dzakakasharara kana zvisina kuenzana dzakapfekwa uye dzisina kusimba girazi-yakatarisana flanges uye tembiricha-kuchinja-chisimbiso nguva. Tinogona kusarudza Gore, Klinger, Garlock, Sealon uye mamwe akawedzera PTFE mapepa evatengi kuburitsa anodiwa gaskets kune vatengi.

Advantage

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.

Kuramba kwemamiriro ekunze-kune hupenyu hwekuchembera hwakanakisa mumapurasitiki.

High lubrication-ndiyo yakaderera coefficient of friction muzvinhu zvakasimba.

Kusina-kunamatira-zvinoreva kuti kudzvinyirirwa kwepamusoro muchinhu chakasimba kuduku uye hakunamati kune chero chinhu. Iyo mechanical properties ine diki diki friction coefficient, iyo inongova 1/5 yeiyo polyethylene. Ichi chinhu chakakosha cheperfluorocarbon surface. Pamusoro pezvo, nekuti iyo fluorine-kabhoni cheni intermolecular masimba akadzikira zvakanyanya, PTFE haina kunamira.

Isiri-chepfu uye inokuvadza-ine physiological inertia, seyakagadzirwa tsinga yeropa uye nhengo yakasimwa mumuviri kwenguva yakareba pasina maitiro akashata.

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

Kupokana nemwaranzi Polytetrafluoroethylene ine simba rekudzivirira nemwaranzi (104 rad), uye inodzikisira mushure mekuratidzwa nemwaranzi-yakanyanya-simba, uye zvemagetsi uye zvemagetsi zvepolymer zvakadzikira zvakanyanya. Kushandisa Polytetrafluoroethylene inogona kuumbwa nekumanikidza kana extrusion processing; inogonawo kugadzirwa kuita mvura yekuparadzirwa kwekuputira, kunyura kana kugadzira mafiibhi. PTFE inoshandiswa zvakanyanya seyakakwira uye yakaderera tembiricha inodzivirira, corrosion resistant materials, insulating materials, anti-stick coatings, nezvimwewo musimba renyukireya, aerospace, zvemagetsi, magetsi, makemikari, michina, zviridzwa, mita, kuvaka, machira, chikafu nezvimwe. 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 mutsara wekuita kwakanakisisa: kupisa kwekushisa kwepamusoro-kwenguva yakareba kushandiswa kwekushisa kwe 200 ~ 260 degrees, kutsika kwekushisa kwepasi-kuchiri kupfava pa -100 degrees; corrosion resistance-resistant kune aqua regia uye zvose organic solvents; Weather kuramba-kukwegura upenyu mumapurasitiki; high lubrication-ine diki coefficient of friction (0.04) mumapurasitiki; kusanamatira-ine kuderera kwepasi tension muzvinhu zvakasimba pasina kunamatira chero chinhu; isiri-chepfu-ine physiological inertness; yakanakisa magetsi zvivakwa, Yakanakira C-level insulating zvinhu.
