Enkozesa eya bulijjo ey’ebisiba bya fluoroelastomer .

Fluoroelastomer seals, bwe zikozesebwa okusiba yingini, zisobola okukola okumala ebbanga eddene ku 200°C~250°C, era ne zikola okumala akaseera katono ku 300°C, era obulamu bwayo obw’okukola buyinza okuba nga bwe bumu n’obulamu bw’okuddamu okukola yingini, nga buno buba 1000 ~ 5000 flight hours (5~10 years); Bwe kikozesebwa mu makolero g’eddagala, asobola okusiba asidi atali wa kiramu (okugeza, 67% ku asidi wa sulfuric ku 140°C, asidi wa hydrochloric omukuŋŋaanyiziddwa ku 70°C, ne 30% ku asidi wa nitric) , ebirungo ebiziyiza obutonde (nga chlorine hydrocarbons, styrene, highly aromatic gaslene) ne organics (Shurinat hydadene, styrene, highly aromatic gaslene) ne organics (Shurinat hydadene, styrene, highly aromatic gaslene) ne organicsene, sstyrene, highly aromatic gaslomatic) ne organics. phenol, asidi z’amasavu ku 275 °C, n’ebirala); Ekozesebwa mu kuggyamu amafuta mu buziba, esobola okugumira embeera enkambwe ey’okukola eya 149 °C ne 420 empewo; Ekozesebwa mu bisiba by’omukka ebibuguma ennyo, esobola okukozesebwa mu kisenge ky’omukka ku 160 ~ 170 °C okumala ebbanga eddene. Mu kukola silikoni ya monokirisitiri, akozesebwa nnyo okusiba ebbugumu erya fluoroelastomer okusiba ebbugumu eringi (300 °C) wansi w’omukutu ogw’enjawulo - trichlorohydrosilicon, silikoni tetrachloride, gallium arsenide, phosphorus trichloride, trichloroethylene, ne hydrochloric acid 120 120 ⁃.

Mu kukozesa vacuum ennyingi, obugulumivu bw’ennyonyi bwa 200 ~ 300km, puleesa y’empewo eri 133×10-6 PA (10-6mmHg), chloroprene rubber, butyl rubber, butyl rubber esobola okusiigibwa; Obugulumivu bw’ennyonyi bwe busukka mu 643km, puleesa y’empewo ejja kukendeezebwa okutuuka ku 133×10-7PA (10-7mmHg) bino wammanga, fluoroelastomers zokka ze zisobola okusiigibwa mu kifo kino eky’amaanyi. Okutwalira awamu mu nkola y’ekyuma ekifuuwa empewo ennyingi oba ultra-high vacuum nga tonnaba kugikozesa, yeetaaga okuyita mu nkola y’okufumba ey’ebbugumu eringi, ekika kya fluoroelastomer eky’ekika kya 246 esobola okugumira okukaddiwa okw’ebbugumu eringi okwa 200 °C ~ 250 vom voleckiles.

Hose ekoleddwa mu fluoroelastomer esaanira ebbugumu eringi, amafuta n’emikutu egy’enjawulo, gamba ng’amafuta g’ennyonyi, amafuta g’amazzi, amafuta agakola emirundi ebiri (synthetic double ester oil), empewo eyokya ennyo, obutakola bulungi n’ebirala eby’enjawulo (nga chlorinated hydrocarbons ne chlorides endala) eby’entambula, obulagirizi n’ebirala. Ekoleddwa mu waya ya fluoroelastomer ne cable flexing ennungi, n’okuziyiza obulungi. Endabirwamu fiber tape ekoleddwa mu fluoroelastomer esobola okuziyiza ebbugumu eringi eri 300°C n’okukulukuta kw’eddagala. Olugoye lwa aramid olusiigiddwa fluoroelastomer, lusobola okukolebwa mu ttanka za kiraasi ez’amafuta, ebbugumu eringi, asidi ne alkali kiraasi ttanka wakati wa connection expansion tube (enkomerero zombi zisobola okuyungibwa ne metal flange), zisobola okugumira puleesa eya waggulu, ebbugumu eringi n’okukulukuta okw’omu makkati, n’okukyukakyuka kw’okugaziwa kwa ttanka ebbiri okugaziwa n’okukonziba kw’okuyungibwa kwa buffer-Absorling okuyunga. Olugoye lwa nayirooni olusiigiddwa akapiira ka fluorine akakoleddwa mu nsawo y’okusiba tape, ng’ekyuma ekisunsula munda mu ttanka ezitereka akasolya ezitengejja nga zirina ebisiba ebigonvu, zikola kinene mu kusiba, zikendeeza ku kuwuuma kw’okufiirwa kw’amafuta ku ngulu.

Ekika kya 23, Tetrapropyl Fluorine Rubber kisinga kukozesebwa nga Asidi-Okuziyiza, Okusiba Emirundi gy’Eddagala Ery’enjawulo. Hydroxy nitrosofluoroelastomer esinga kukozesebwa ng’ebintu ebikuuma n’ebiziyiza, mu ngeri y’okugonjoola ng’ekizigo ekitayokya, ekisiigibwa ku bitundu by’obusannyalazo ebiziyiza omuliro n’ebitundu ebikola mu oxygen omulongoofu. Ekizimbulukusa kyayo n’akapiira kaayo ak’amazzi bisobola okufuuyira, okusuula n’engeri endala ez’okukola ebintu bingi, gamba ng’engoye ez’omu bwengula, ggalavu, ebikondo bya payipu, emipiira n’ebirala. Era esobola okukozesebwa nga endabirwamu, ekyuma, 'omubiri gw'okwegatta, olugoye olusiiga, okukola sipongi n'okukwatagana n'ekyuma ekikuba emizinga (N2O4) gaasikiti, 'o' empeta, capsule ez'engeri zonna eza seals n'ebirala.

Envumbo ezikoleddwa mu kika kya G-type fluoroelastomer zirina omulimu gw’okuziyiza omukka ogw’ebbugumu eringi, petulooli wa methanol oba okuziyiza kwa petulooli okw’akawoowo okw’akawoowo okw’amaanyi okutasobola kutuukirizibwa nga tukozesa vitona, B, E ne fluoroelastomers endala; GLT-type fluoroelastomers, phosphorus chlorinated rubbers, perfluoroether rubbers, n’ebirala, zirina ebbugumu erigazi erikola, okugonvuwa okw’ebbugumu eri wansi, okusiba elasticity, n’ebirala. Perfluoroether rubber era erina okuziyiza okukulukuta okw’enjawulo eri emikutu gy’amawulire, nga kino kikozesebwa nnyo mu tekinologiya ow’omulembe ow’amakolero g’amagye.
