Zero Leakage PTFE Valve Seat Butterfly Valve Parts DN50 - DN600
Mhandara PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ifluorocarbon yakavakirwa papolymer uye kazhinji ndiyo inonyanya kurwisa kemikari pamapurasitiki ese, ichiramba ichichengetedza kunaka kwemafuta uye magetsi ekudzivirira. PTFE zvakare ine yakaderera coefficient yekukwesha saka yakanakira akawanda akaderera torque application.
Ichi chinyorwa hachisi - chinosvibisa uye chinogamuchirwa neFDA chekushandisa chikafu. Kunyange zvazvo michina yePTFE yakaderera, ichienzaniswa nemamwe mapurasitiki akagadzirwa, maitiro ayo anoramba achishanda pamusoro pehupamhi hwekushisa.
Tembiricha tembiricha: - 38 cei c kusvika + 230 ° C.

Zvakanakira:
PTFE inomirira PolyTetraFluoroEthylene, inova izwi remakemikari repolymer (CF2)n.
Polytetrafluoroethylene (PTFE) inhengo yethermoplastic yemhuri yefluoropolymer yemapurasitiki uye ine yakaderera coefficient yekukwesha, yakanakisa insulating zvivakwa.
PTFE ikemikari inert kune zvakawanda zvinhu. Iyo zvakare inogona kumirisana nekupisa kwakanyanya uye inonyatsoziva kune yayo anti- stick zvivakwa.
Kusarudza kodzero yekurudyi renziyo kazhinji inonyanya kuoma sarudzo mukati Ball Valve Kusarudzwa. Kubatsira vatengi vedu panguva iyi, isu tinoda kupa ruzivo rwekukumbira kwevatengi.
PTFE zvigaro zvevharuvhu zvinogadzirwa neUS zvinoshandiswa zvakanyanya mumucheka, chiteshi chemagetsi, petrochemical, kudziyisa uye firiji, mishonga, kuvaka ngarava, simbi, chiedza indasitiri, kuchengetedza kwezvakatipoteredza, Pepa Indasitiri, Shuga Indasitiri, Compressed Air uye mamwe minda.
Kuita kwechigadzirwa: kukwirira kwekushisa kwepamusoro, yakanaka asidhi uye alkali kuramba uye mafuta kuramba; ine yakanaka rebound resilience, yakasimba uye yakasimba isina kudonhedza.
