(5) Okuziyiza embeera y’obudde ennungi, obuziyiza n’obuwuka obuziyiza endwadde ku kapiira akasinga okuziyiza ozone.
(6) omulimu omulungi ennyo ogw’amaanyi ag’ebbugumu eringi n’okunyigirizibwa okw’olubeerera okw’okukyukakyuka, eby’obutonde eby’ebbugumu eringi n’ebyuma ebisukkulumye ku elastomer endala ezisinga obungi; Ng’oggyeeko omulimu gw’ebbugumu eri wansi gusinga kukwatagana, bingi ku by’obugagga bya fluoroelastomer mu kapiira bye bisinga okubeera ebirungi, oba okuteekebwa mu kifo kyayo naddala okuziyiza kwayo amafuta n’eddagala, okugumira okuvunda kw’amazzi agasukka mu bikumi bisatu, era n’okusingawo okutali kwa bulijjo kwe kuziyiza okuziyiza ebikolwa by’okusituka si kinene; fluoroelastomer low-temperature performance is general, but Even if the static sealing effect used in conditions close to absolute zero is also satisfactory, fluoroelastomer has most of the other rubber does not have excellent performance, almost indispensable sealing material in high temperature and strong corrosive environments, has been in the ever-changing automotive, chemical, office automation and semiconductor manufacturing and other industries play an indispensable and important omugaso!
3、Embeera ya FKM mu makolero asatu .
Amakolero g’okukola mmotoka, ebyuma n’amakolero g’amafuta geeyongera okukaluba embeera z’okukoleramu eza kapiira n’obuveera okusiba okusiba ku bbugumu eringi, okuziyiza amafuta, okuziyiza eddagala n’embeera enzibu ey’ebintu eby’omubiri n’ebyuma eby’obwetaavu obw’amaanyi, omupiira gwa nitrile ogw’ekinnansi teguyinza kutuukiriza byetaago by’obwetaavu gulina okukozesebwa n’omugatte ogw’enjawulo ogwa fluorine rubber n’ebika ebirala ebya kapiira. Fluoroelastomer olw’omutindo gwayo omulungi ennyo ebadde ekozesebwa nnyo mu makolero gano.FKM ekozesebwa nnyo mu makolero gano n’omutindo gwayo omulungi ennyo.
Okukozesa FKM kweyongera mu nsi yonna, era ezisinga zikozesebwa mu mulimu gw’emmotoka. Such as the current world production of fluoroelastomer has exceeded 8000t, of which 60 a 70% with automotive products, mainly the manufacture of various types of oil seals (rotary, reciprocating), including engine oil seals, transmission oil seals (such as: crankshaft before and after the oil seals, gear compartment oil seals, camshafts, hubs and half-shafts oil seals, valve guides oil Ebisiba, n’ebirala), ‘Ng’oggyeeko ebisiba ebitambuza, ebyuma ebiyingiza ggaasi o-ring, ebisiba enkola y’amafuta (okugeza, seals za fuel injection unit, fuel pump diaphragms, pump seals, injector 0-ring, accelerator pump bowl, filter seals, carburetor seals ne petulooli pump seals).
Okulongoosa mu nkola ya yingini y’emmotoka, okukozesa woyiro wa yingini omupya (nga SF) n’okulongoosa mu kusiiga, ebirungo ebikosa ebikosa, ekifuula ebbugumu lya yingini okweyongera, okukozesa amafuta aga seals kuyinza okuba waggulu nga 30m/s, okukozesa ebbugumu okutwalira awamu kutuuka ku 150 °C; Obutonde bw’eddagala bweyongera okuba obw’obukambwe, ate emmotoka oluvannyuma lwa crankshaft ya crankshaft ekyusiddwa nga erina silicone seals n’ekintu eky’okwonooneka egenda yeeyongera okuba ey’amaanyi, okukozesa fluoroelastomer seals kuyinza okuba enkozesa ya viton seals kiyinza okulongoosa okuziyiza amafuta, ebbugumu, okugaziwa service life (up to 500000000/0), okukendeeza ku 400%.60%.
Amakolero g’ebyuma, ebyuma ebikuba ebyuma ebiwanvu eby’ekika kya high-line rolling mill shaft diameter double-sides sealing amawanga amalala okutwalira awamu gakozesa NBR, ekizibu ekisinga kwe kuba nti ekintu kino kyangu okukaddiwa, okwambala n’okukutula, okuwangaala okutono, okutwalira awamu 3. Wiiki 5, ekyuma ekigenda mu maaso kye kyuma ekikulu eri ebitongole by’ebyuma, abawagizi ba ssilingi seals be fluorine rubber material.
Amafuta okusima amafuta seals goolekedde embeera y’emirimu esinga okukaluba era enkambwe obutonde, olw’okusima okutuuka mu nzizi enzito, enkulaakulana y’oluzzi oluwanvu ennyo, enzizi z’amafuta wansi ebinnya ebiziyiza ebinnya birina okwolekagana n’embeera y’emirimu esingako obuzibu era enkambwe (ebbugumu eringi n’ery’awaggulu, puleesa enkulu, ekibiriiti ekingi petroleum, amaanyi aga corrosive nga galimu h2s, H20, C02, nga bwe kiri ku ssinga eby’okukozesa ebiziyiza okugwa mu bika bya H2s, H20, C02, nga bwe kiri ku bika ebisinga obungi eby’okuvunda ku bika bya H2s, H20, C02, nga bwe biri kitonnyeze). Emabegako, ebisiba bya kapiira ebikozesebwa ku byuma ebiggyamu amafuta bisinga kwesigamiziddwa ku kapiira ka Nitrile nga kaziyiza bulungi amafuta, era nga bikoleddwa mpolampola ne bifuuka fluorine rubber, silicone rubber ne HNBR rubber, n’ebirala, era oluusi ne byetaaga n’okukozesa tetra-propyl fluorine, perfluoreders rubber ne downleater endala ez’enjawulo, nga mu contact ne sulfur-confuning cruce-containing cruce-contain cruce-contain cruce-contain cruven-contain cruce-contain. Valiva z’obukuumi ne packers mu rubber seals zibadde zikozesebwa nnyo mu kukozesa fluorine rubber. Okugeza, kapiira ka fluorine kabadde kakozesebwa nnyo mu bipiira ebisiba ebinnya ebikka wansi n’eby’omutwe gw’oluzzi ebikwatagana n’amafuta agatali malongoose agalimu ekibiriiti, gamba ng’okuziyiza okufuuwa n’okupakinga.
