Fluoroelastomer seals, loko yi tirhisiwa ku pfalela njhini, yi nga tirha nkarhi wo leha eka 200°C~250°C, naswona yi tirha nkarhi wo koma eka 300°C, naswona vutomi bya yona byo tirha byi nga fana na vutomi byo tirha nakambe bya njhini, lebyi nga 1000~5000 wa tiawara ta ku haha (5 ~ 10 wa malembe); when used in the chemical industry, it can seal the inorganic acid (eg, 67% of sulfuric acid at 140℃, concentrated hydrochloric acid at 70℃, and 30% of nitric acid) , organic solvents (such as chlorinated hydrocarbons, benzene, highly aromatic gasoline) and other organics (such as butadiene, styrene, propylene, phenol, ti-acid ta mafurha eka 275 °C, na swin’wana); Yitirhisiwa eka ku humesiwa ka oyili ya deep-well, yinga tiyisela swiyimo swo tika swa ntirho swa 149 °C na 420 atmospheres; Yitirhisiwa eka ti superheated steam seals, yinga tirhisiwa eka steam medium eka 160 ~ 170 °C kuringana nkarhi woleha. Eka vuhumelerisi bya silicon ya monocrystalline, ti fluoroelastomer seals leti tirhisiwaka ngopfu ku pfalela mahiselo yale henhla (300 °C) ehansi ka switirhisiwa swo hlawuleka - trichlorohydrosilicon, silicon tetrachloride, gallium arsenide, phosphorus trichloride, trichloroethylene, na hydrochloric acid 120.
Eka switirhisiwa swale henhla swa vacuum, loko vukulu bya xihahampfhuka bya 200~300km, ntshikelelo wa moya wuva 133×10-6 PA (10-6mmHg), chloroprene rubber, butyl rubber, butyl rubber yinga cheriwa; Loko ku tlakuka ka xihahampfhuka xo tlula 643km, ntshikelelo wa moya wu ta hungutiwa ku ya eka 133×10-7PA (10-7mmHg) Leswi landzelaka, i ti fluoroelastomers ntsena leti nga tirhisiwaka eka vacuum leyi ya le henhla. Hi ntolovelo eka sisiteme ya le henhla ya vacuum kumbe ultra-high vacuum device before yi tirhisiwa, yi lava ku hundza eka vutshunguri bya ku baka hi mahiselo ya le henhla, 26-type, 246-type fluoroelastomer yi nga tiyisela ku dyuhala ka mahiselo ya le henhla ka 200 l ya rhaba ya le henhla na cosmic.
Hose leyi endliweke hi fluoroelastomer yi lulamerile eka swiyimo swa mahiselo ya le henhla, oyili na swihangalasamahungu swo hlawuleka, ku fana na oyili ya mafurha ya swihahampfhuka, oyili ya hayidiroliki, oyili ya xivumbeko xa double ester, moya wo hisa wa mahiselo ya le henhla, swihangalasamahungu leswi nga riki swa ntumbuluko swo hisa na swin’wana swo hlawuleka (ku fana na tihayidirokhaboni leti nga na chlorinated na ti-chloride tin’wana) ta ku fambisiwa, nkongomiso na swin’wana. Yi endliwe hi waya wa fluoroelastomer na ku olovisiwa ka tikhebulu kahle, na ku pfaleriwa kahle. Thepi ya fibre ya nghilazi leyi endliweke hi fluoroelastomer yi nga lwisana na mahiselo ya le henhla ya 300°C na ku bola ka tikhemikhali. Aramid cloth leyi funengetiweke hi fluoroelastomer, yinga endliwa eka swimilani swa petrochemical, mathangi ya mahiselo yale henhla, acid na alkali class exikarhi ka connection expansion tube (makumu hamambirhi yanga hlanganisiwa na flange ya nsimbi), swinga tiyisela ntshikelelo wale henhla, mahiselo yale henhla xikan’we na ku bola ka le xikarhi, na ku onhaka ka xiave xa mathangi mambirhi na ku hlangana ka ku hlanganisiwa ka ti bunffer shock-absorbing. Nylon cloth leyi funengetiweke hi rhaba ya fluorine leyi endliweke hi nkwama wo pfala thepi, tani hi ndzhawu yo basisa endzeni ka mathangi yo hlayisa lwangu lawa ya papamalaka na swipfalo swo olova, yi tlanga xiave eka ku pfalela, yi hunguta ku cinca cinca ka ku lahlekeriwa ka le henhla ka oyili.
Muxaka wa 23, rhaba ya tetrapropyl fluorine yi tirhisiwa ngopfu tanihi swiendlakalo swo pfalela leswi nga ni asidi, leswi nga ni khombo swa tikhemikhali to hlawuleka. Hydroxy nitrosofluoroelastomer yitirhisiwa ngopfu tani hi switirhisiwa swo sirhelela na switirhisiwa swo pfalela, hi xivumbeko xa solution tani hi xifunengeto lexi nga hisiki, lexi tirhisiwaka eka swiphemu swa elektroniki leswi nga hisiki na swiphemu leswi tirhaka eka okisijini yo basa. Nchuluko wa yona na rhaba ya mati swinga fafazeriwa, ku hoxiwa na tindlela tin’wana to endla switirhisiwa swotala, kufana na swiambalo swa cosmic, magilavu, mabandhi ya tiphayiphi, mabolo na swin’wana. Swi nga tlhela swi tirhisiwa tanihi nghilazi, nsimbi, 'miri wa rimbewu, xinamarheti xa malapi, ku endliwa ka swiponci ni ku khumbana ni tigasiki ta rocket propellant (N2O4), 'o' ring, capsule tinxaka hinkwato ta swisirhelelo ni swin'wana.
Ti seals leti endliweke hi G-type fluoroelastomer series tina matirhelo ya high temperature steam resistance, methanol petrol kumbe high aromatic hydrocarbon gasoline resistance leswinga fikeleriwa hiku tirhisa VITONA, B, E na swin’wana swa fluoroelastomers; GLT-type fluoroelastomers, phosphorus chlorinated rubbers, perfluoroether rubbers, na swin’wana, swina mahiselo yo anama yo tirha, ku olova ka mahiselo yale hansi, ku pfaleriwa ka elasticity, na swin’wana. Perfluoroether rubber yitlhela yiva na ku lwisana lokukulu ka corrosion eka swihangalasamahungu, leswi tirhisiwaka ngopfu eka thekinoloji ya xiyimo xale henhla ya indasitiri ya masocha.
