Irabha ye-fluorine uhlobo lwerabha yokwenziwa equkethe ama-athomu e-fluorine. Inokumelana nokushisa okuhle kakhulu, ukumelana ne-oxidation, ukumelana nowoyela kanye nokumelana nomuthi. Isetshenziswa kakhulu kwezokundiza, imboni yamakhemikhali, i-petroleum, izimoto kanye neminye iminyango yezimboni njengezinto zokuvala, izinto ezimelana naphakathi nendawo kanye nezinto zokuvikela. Irabha yokwenziwa equkethe ama-athomu e-fluorine esakhiweni sayo samangqamuzana.
Ivamise ukuvezwa ngenani lama-athomu e-fluorine amayunithi aqukethe i-fluorine ku-copolymer. Isibonelo, i-fluororubber 23 iyi-copolymer ye-vinylidene fluoride ne-chlorotrifluoroethylene. I-Fluororubber imelana nezinga lokushisa eliphezulu, ukugqwala kwamafutha kanye namakhemikhali.
Izinzuzo ze-fluororubber:
1. Ukumelana nokushisa okuphezulu okuhle kakhulu: izinga lokushisa lesevisi lisukela - 60 ℃ kuya ku-250 ℃. Ukumelana nowoyela okuhle kakhulu: ukumelana nowoyela oshisayo oshisa kakhulu, uwoyela wokugcoba oqukethe isulfure, uwoyela we-hydraulic, uwoyela we-diester, i-silicate ester namanye amafutha angcono kunamanye ama-rubber.
3. Ukumelana okuhle kakhulu ne-corrosion medium eqinile kanye ne-oxidant eqinile; Ukuzinza kwayo emithonjeni yezindaba eyonakalisayo eqinile njenge-nitric acid evuthayo, i-sulfuric acid egxilile, i-hydrochloric acid, i-hydrogen peroxide kanye ne-alkali egxilile kungcono kunamanye amarabha.
4. Izakhiwo ezinhle zemishini, ukufakwa kukagesi nokumelana nemisebe.
5. Ukumelana okuhle ne-vacuum ephezulu.
Ububanzi bokusebenza be-fluororubber:
1. Lapho irabha ye-fluorine ithinteka umswakama namanzi noma lapho izinga lokushisa likhuphuka, ushintsho luncane. Ngisho noma i-silicon dioxide ekhiqizwa ukushiswa kwe-short-circuit iseyi-insulator, iqinisekisa ukuthi imishini kagesi iyaqhubeka nokusebenza, ngakho ifaneleka ukwenza izintambo, izintambo nezintambo zokuhola.
2. I-fluoroplastic tube ingasetshenziselwa ukudlulisa nokuvala i-asidi eqinile ehlukahlukene kanye ne-alkali, umusi, umoya oshisayo, uwoyela oshisayo nolunye uketshezi. Ingase futhi isetshenziselwe izinto zasendlini, izibani kanye nemishini yezokwelapha; 3. Ingcindezi yokusebenza ye-fluororubber tube (0.5-3.0 MPa) ingavikelwa ngesembozo senethi esihlangene nesensimbi engagqwali.
4. I-Fluoroplastic strip nayo isetshenziselwa ijakhethi yocingo endaweni yokusebenza enokhahlo.;
5. I-Fluororubber inokushisa okuphezulu okuvelele nokumelana nokugqwala, futhi inedumela lenkosi yenjoloba. Ingacutshungulwa ibe yishubhu yenjoloba, itheyiphu yokunamathisela, ifilimu, i-gasket, (uhlaka) uphawu lukawoyela, “O” indandatho, indandatho ethi “V”, njll., esetshenziswa kabanzi kwezokundiza, izimoto, uphethiloli, imboni yamakhemikhali, ezokuxhumana, insimbi neminye imikhakha.
Njengoba sonke sazi, i-valve ngayinye kufanele isebenzise izinto zokuvala ezihlukene, njenge-ethylene propylene rubber (EPDM), irabha ye-nitrile (NBR), i-polytetrafluoroethylene (PTFE), i-fluororubber (Viton), i-silicone irabha (SEP), ukushisa nokugqoka i-EPDM yenjoloba eqinile, i-carbide ehlanganisiwe, i-alloy steel.
