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, uku ichichengeta yakanakisa kupisa uye magetsi ekudzivirira zvinhu. 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 yakasiyana: -38°C kusvika +230°C.
Ruvara: chena

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 chigaro chakakodzera chemhete kazhinji ndicho chisarudzo chinonetsa mukati Ball Valve Selection. Kuti tibatsire vatengi vedu panguva iyi, isu takagadzirira kupa ruzivo pamusoro pekukumbira kwevatengi.
PTFE zvigaro zvevharuvhu zvinogadzirwa neUS zvinoshandiswa zvakanyanya mumucheka, chiteshi chemagetsi, petrochemical, kupisa uye firiji, mishonga, kuvaka ngarava, simbi, indasitiri yemwenje, kuchengetedza kwezvakatipoteredza, Pepa Indasitiri, Shuga Indasitiri, Compressed Air uye mamwe minda.
Kuita kwechigadzirwa: kukwirira kwekushisa kwepamusoro, yakanaka acid uye alkali kuramba uye mafuta kuramba; ine yakanaka rebound resilience, yakasimba uye yakasimba isina kudonhedza.
