Fluorine rabha imhando yerabha yakagadzirwa ine maatomu efluorine. Iyo ine yakanakisa kupisa kupisa, oxidation kuramba, mafuta kuramba uye kuramba zvinodhaka. Inonyanya kushandiswa mundege, indasitiri yemakemikari, peturu, mota uye mamwe madhipatimendi eindasitiri sechinhu chekuisa chisimbiso, yepakati inodzivirira zvinhu uye insulating zvinhu. Rabha rekugadzira rine maatomu efluorine muchimiro chayo chemolecular.
Inowanzo kuratidzwa nehuwandu hwemaatomu efluorine ezvikamu zvine fluorine mune copolymer. Semuenzaniso, fluororubber 23 icopolymer yevinylidene fluoride uye chlorotrifluoroethylene. Fluororubber inopesana nekupisa kwakanyanya, mafuta uye kemikari corrosion.
Zvakanakira zve fluororubber:
1. Yakanakisa kupisa tembiricha kuramba: tembiricha yebasa inotangira - 60 ℃ kusvika 250 ℃. Yakanakisa kupikisa mafuta: kupikisa kupisa kwakanyanya kwemafuta emafuta, sulfur-ine yekuzora mafuta, hydraulic mafuta, diester mafuta, silicate ester uye mamwe mafuta ari nani kupfuura mamwe marubha.
3. Kunyanya kupikisa kune yakasimba corrosive medium uye yakasimba oxidant; Kugadzikana kwayo mune yakasimba corrosive media senge fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxide uye concentrated alkali iri nani pane mamwe marubha.
4. Good mechanical properties, magetsi ekudzivirira uye neradiation resistance.
5. Kuramba kwakanaka kune vacuum yakakwirira.
Chiyero chekushandiswa kwefluororubber:
1. Kana iyo fluorine rubber inobatwa nehunyoro nemvura kana kana kutonhora kuchikwira, kuchinja kuduku. Kunyange kana iyo silicon dioxide inogadzirwa nekutsva-kwenguva pfupi ichiri insulator, inoita kuti magetsi arambe achishanda, saka akakodzera kugadzira waya, tambo uye waya dzinotungamirira.
2. Fluoroplastic chubhu inogona kushandiswa pakufambisa uye kuvhara zvakasiyana-siyana yakasimba asidhi uye alkali, chiutsi, mhepo inopisa, mafuta anopisa uye mamwe mvura. Inogonawo kushandiswa kumidziyo yemumba, kuvheneka uye michina yekurapa; 3. Kumanikidza kwekushanda kwe fluororubber tube (0.5-3.0 MPa) inogona kudzivirirwa nejoint uye stainless simbi net cover.
4. Fluoroplastic strip inoshandiswawo kune waya bhachi munzvimbo yakaoma yekushanda.;
5. Fluororubber ine yakanakisa tembiricha yepamusoro uye corrosion resistance, uye ine mukurumbira wemambo werabha. Inogona kugadzirwa kuita rabha chubhu, inonamira tepi, firimu, gasket, (framework) chisimbiso chemafuta, "O" mhete, "V" mhete, nezvimwewo, iyo inoshandiswa zvakanyanya mundege, mota, peturu, indasitiri yemakemikari, kufonera, chiridzwa uye zvimwe minda.
Sezvatinoziva tose, vharafu imwe neimwe inofanira kushandisa zvakasiyana-siyana zvekuisa chisimbiso, zvakadai se ethylene propylene rubber (EPDM), nitrile rubber (NBR), polytetrafluoroethylene (PTFE), fluororubber (Viton), silicone rubber (SEP), kupisa uye kupfeka EPDM inopikisa, cemented carbide, alloy steel.
