Ziva nezve polytrifluoroetyylene pctfe

Chii chinonzi pctfe (polychlotrotrluoroetherylene) uye ndedzipi nzvimbo dzaro uye dzinoshandiswa?

Polychlototrifhandolleuorohone (PCFF) Zita reChinese: Polychlotrotiotherylene Chirungu zita: PolychlotrotiRluorolene, Pctfe. polymer of chlotrifluorohylene. Bcduviation prfe, ipfupi yeTrifluoro (F3). Kunyungudza tembiricha ye123 Rate.pctfe is a crystalline polymer, inonyungudika polly of 425f, density of 2.13G / CC (GRAMS / Cubic Centimeter). ). Hardness Hardness D85.

PCFA inyaya yeFluine iyo inogona kuongororwa ne inopisa-nyungudika uye ndeye kosi yetemoplastic.

Zvigadzirwa zvePTCFE ZVINOGONESWA NEZVINHU ZVINOGONESESA UYE KUKOSHESA KWEMAHARA KUTI UYE KUKOSHESA KWEMUFANANIDZO WEMUFANANIDZO WEMUKADZI NEMAHARA.

Iko kushandiswa kukuru kwePCFT SEATE SEZVINOGADZIRA-CORROSION YEMAHARA matangi, mavharuvhu, mapombi, etc., pamwe nezvigadzirwa zvakadai sePIPE FITTTINGS uye Midziyo yeAyedzani. Panguva imwecheteyo, PCTFA inogona kushandiswawo zvisimbiso zvemagetsi, zvinopfeka magiya, uye zvigadzirwa zvekurapa.

Pane nzira dzakasiyana siyana dzekugadzirisa, mukuwedzera kune iyo thermoplastic kugadzirisa uye kuumbwa, inogona zvakare kuongororwa mumirazvo uye matanda ekucheka kwechipiri nekugadzira muzvikamu zvakakwirira zvekunyora.

Polychlototrruorooroleneery gasket low tembiricha inodzivirira pctfe gasket lng yakadzika pasi gasket

Polychlototreiflluorolene, akapfupikiswa sePCFA, iri polymer compound yakagadzirwa kubva kuTrifluoroetherylene nePolmerization. Kurema kweLolecular yeMweya kana WAX-Like. Yakakwira Molecular uremu ine chena yakasimba kana yakapararira mvura. Solid density 2.1 ~ 2.2, inonyungudika point 208 ~ 210 ℃. Kupokana nekupisa, acid, alkali uye organic solides (kunze kwekunonoka), asi kwete kupokana nekunyungudika caustic uye elemental fluorine. Kemical kurwisa ndeyechipiri chete kune ptfe. Inogona kushandiswa seinjiniya mapurasitiki.

Tensile Simba 3.096 ~ 4.135 MPA (316 ~ 42 Kgf / cm2). Kazhinji inoshandiswa mumidziyo yemakemikari ine yakakwirira performance zvinodiwa, ine mangozi, radio midziyo, capacitors uye kupisa kana kupisa kupisa kwakasimba. Kupararira kunoshandiswa kugadzira maAnti-Corrosion COatings uye mafirimu.

Nzira dzeSynthesis dzePCTFE rinosanganisira polymerization, mhinduro polmerization uye kupararira polmerization, etc. yakagadzirirwa neyemahara polmerization ne peroxide so tangtator.

Polytrifilluorolehlene ine simba rakanakisa

PCTFE yakakodzera kushandiswa mukusangana neakasimba midhiya inokanganisa, mashandiro eganda, uye zvemagetsi zvinoshandiswa muindasitiri yemakemikari, Atomi Indasitiri yeAtomi, Asi mutengo wayo unodhura kupfuura ptfe. Yakadzika molecular uremu polytetrafluorohone ine yakakura density, hunhu hwekushisa-tembiricha, uye inogona kusunganidzwa, uye inokweretesa mafuta uye chiyero chemafuta ekufambisa gyroscope.

PCTFE ine kuomarara, kupisa-tembiricha kudzikisira, kutonhora kuyerera kuramba, ndiyo yakanakisa kuisirwa mari yekuisa kune yakaderera-tembiricha uye yakanyanya kudzvinyirira mamiriro ezvinhu, uye ine yakasarudzika mashandisirwo emhando yepamusoro.

Zvishandiso:

1, Bata nevakawanda vanokanganisa midhiya, yakakwirira-yekumanikidza system kuiswa chisimbiso uye gasket zvinhu, kutarisa hwindo rewindows turniprent zvinhu, nezvimwewo ..

2.Electrical zvinhu zvekushandisa, nezvimwe.

3.w Molecular uremu PCTFE inoshandiswa sekuisa mucherechedzo weiyo yakakwira curosive yepakati pakati, lubricating grease uye chiyero chehunhu hwekufambisa gyroscope.

Hony Purasiki ine dzakasiyana siyana dzePKTFO TODS, machubhu uye mahwendefa pamwe chete nemafuta ekuisa gatsiti, gasi, zvigaro zvevharanda zvichingodaro. Zviitiko chaizvo zvinoreva nezvePTFE zvigadzirwa zvinotsanangurwa
