fluorine roj hmab yog ib hom roj hmab hluavtaws uas muaj fluorine atoms. Nws muaj kev tiv thaiv kub zoo, oxidation tsis kam, roj tsis kam thiab tshuaj tiv thaiv. Nws yog tsuas yog siv nyob rau hauv aviation, tshuaj lom neeg kev lag luam, roj av, tsheb thiab lwm yam industrial departments li sealing khoom, nruab nrab resistant khoom thiab insulating khoom. Cov roj hmab hluavtaws uas muaj fluorine atoms hauv nws cov qauv molecular.
Nws feem ntau yog qhia los ntawm tus naj npawb ntawm fluorine atoms ntawm fluorine-muaj units hauv copolymer. Piv txwv li, fluororubber 23 yog ib copolymer ntawm vinylidene fluoride thiab chlorotrifluoroethylene. Fluororubber tiv taus kub, roj thiab tshuaj lom neeg corrosion.
Qhov zoo ntawm fluororubber:
1. Kev kub siab ua haujlwm zoo heev: qhov kev pabcuam kub ntawm - 60 ℃ txog 250 ℃. Cov roj zoo heev: kev tiv thaiv rau cov roj kub kub, cov roj uas muaj sulfur-muaj lubricating roj, roj hydraulic, roj diester, silicate ester thiab lwm cov roj zoo dua li lwm cov roj hmab.
3. Kev ua haujlwm zoo heev rau qhov nruab nrab muaj zog corrosive thiab muaj zog oxidant; Nws ruaj khov nyob rau hauv muaj zog corrosive xov xwm xws li fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxide thiab concentrated alkali yog zoo dua li lwm yam roj hmab.
4. Zoo txhua yam khoom, hluav taws xob rwb thaiv tsev thiab hluav taws xob tiv thaiv.
5. Kev ua haujlwm zoo rau lub tshuab nqus tsev siab.
Daim ntawv thov Scope ntawm fluororubber:
1. Thaum cov roj hmab fluorine cuam tshuam los ntawm cov dej noo thiab dej los yog thaum kub nce, qhov kev hloov me me. Txawm hais tias cov silicon dioxide tsim los ntawm luv luv-circuit combustion tseem yog ib qho insulator, nws ua kom cov khoom siv hluav taws xob txuas ntxiv mus, yog li nws tsim nyog rau kev ua cov xov hlau, cables thiab cov hlau lead.
2. Fluoroplastic raj tuaj yeem siv rau kev xa tawm thiab sib khi ntau yam muaj zog acid thiab alkali, chav dej, cua kub, roj kub thiab lwm yam kua dej. Nws kuj tseem siv tau rau cov khoom siv hauv tsev, teeb pom kev zoo thiab khoom siv kho mob; 3. Kev ua haujlwm siab ntawm fluororubber tube (0.5-3.0 MPa) tuaj yeem tiv thaiv los ntawm kev sib koom ua ke thiab stainless hlau net npog.
4. Fluoroplastic sawb kuj yog siv rau lub tsho hlau hauv qhov chaw ua haujlwm hnyav.;
5. Fluororubber muaj qhov kub thiab txias thiab corrosion kuj, thiab muaj lub koob npe nrov ntawm huab tais ntawm roj hmab. Nws tuaj yeem ua tiav rau hauv cov raj roj hmab, daim kab xev nplaum, zaj duab xis, gasket, (lub hauv paus) roj foob, "O" nplhaib, "V" nplhaib, thiab lwm yam, uas yog siv dav hauv aviation, tsheb, roj av, tshuaj lom neeg kev lag luam, kev sib txuas lus, ntsuas thiab lwm yam kev lag luam.
Raws li peb txhua tus paub, txhua lub valve yuav tsum siv cov ntaub ntawv sib txawv, xws li ethylene propylene roj hmab (EPDM), nitrile roj hmab (NBR), polytetrafluoroethylene (PTFE), fluororubber (Viton), silicone roj hmab (SEP), tshav kub thiab hnav resistant roj hmab EPDM, cemented carbide, hlau alloy.
