Maitiro ekuita e fluoroplastics

Performance Properties yeFluoroplastics: PolytetraFluorohlene, Perfluoro-pe) Polymin's Commy Froride (PVDF) Fluoride (PVDVINGE) Trifluoroetheryle) zvakare ine chlorine maatomu. Kuita kwakanaka kwazvo kweFluoroplastics kunoitwa neakakwirira electronegativity pakati peokisijeni uye fluorine maatomu.

1. Formal Properties Fluoroplastics ine murazvo unodzora uye wakanakisa kupisa kupfuurira kusvika pamakumi maviri neshanu, uye inogona kupfupisa. kushandiswa pa12 ℃. Fluoroplastics yakadai sekureba-kwenguva refu tembiricha yekushisa ichakonzera zvakare size size shanduko, mukugadzirwa kwemidziyo inoyerera, kunyanya, inofanira kutarisisa.

2. Chemical Resistance Line Fluorolastics ine yakanakisa kurwisa mutsara uye solvent kuramba Asi kunyunguduka kweAlkaline Pasi, Fluorine, Hylorine Hydrocarbons inokanganisa pane izvi pCFFLASTics, etfe muFluoroplastics, mhemberero yemakemikari iri kushaya simba, asi iri nani pane mamwe mapurasitiki kana kupokana.

3. Magetsi emagetsi eFluoroplastics Simba mashandiro, kunyanya yakakwira-frequency yekuita maitiro akaoma kuenderana nezvimwe zvinhu. PTFE, FEP, PFA MOLECULUT YAKANAKA uye DZESVONDO DZESVONDO DZINOGARA, DZINOGARA DZESVONDO DZESVONDO DZINOGARA, Difelectric Kurasikirwa. Mune iyo PVDF zvakare ine yakakosha piezoelectricity uye kubhadharisa, inogona kushandiswa kugadzira piezoelectric profiles.

4. Zvisikwa zvemidziyo performance fluorplastics molecular chimiro chePeroxide, klorine maatomu kuti asimbise simba rakajeka rinovandudzwa. PTFE uye yePCTFA KUSVIRA Tembiricha yakanyanya kuderera, ichiratidza yakanaka kwazvo tembiricha yekushisa. PTFE ine yakaderera kupokana kupokana uye yakakosha yekuzvifunga-inokwereta zvivakwa. Nekudaro, ptfe zvakare ine yayo chaiyo brasive diamondi-giredhi kuyerera uye zvimwe zvinetso. Inogona kutorwa kuti uwedzere akasiyana-siyana mafirita kuti uvandudze kupfeka kupokana, kubvisa kuyerera kunotonhora.

5. Non-Sticess Fluoroplastics ine yakakosha isiri-tsvimbo zvivakwa. Kunyanya mumanyorerwe ePTPE, FEP, PFA uye imwe yakakwira Fluorine Zvemukati, nzvimbo yekunhuhwirira yemukati inonyanya kukura, kuitira kuti mvura iri mumvura yezvinhu zvigadzirwa zveFluoroltic mune imwe spherical chimiro. Hazvisi nyore kushuvira neepoxy resin, saka zvakajairika kuti zvigadzire kitchenware pamusoro zvisiri-tsvimbo Xu Layer.
