Ukusetshenziswa okujwayelekile kwezimpawu ze-fluololastomer

Ama-Fluoloelastomer Seals, lapho asetshenziselwa ukubekwa uphawu kwenjini, angasebenza isikhathi eside ngo-200 ℃ ~ 250 ~ 250, futhi asebenze isikhashana ngo-300 ℃, futhi impilo yawo yokusebenza angalingana nokuphila kwe-Injini Rework, okuyi-1000 ~ 5000 amahora wendiza); Uma isetshenziswa embonini yamakhemikhali, isib, 67% ye-sulfuric acid ku-140 ℃, i-hydrochloric acid ngo-70 ℃, i-bezene, i-throrinated hydrocarbons) kanye nezinye izinto ze-nitric (i-buthadines, i-perylene, i-propylene, i-propylene, i-propylene, phenol, fatty acids ku-275 ℃, njll.); isetshenziswa ekukhishweni okujulile kawoyela, ingamelana nezimo ezinzima zokusebenza kuka-149 ℃ no-420. Isetshenziswa ezinkampanini ze-Steate ezihle kakhulu, ingasetshenziswa ku-Steam Medium ku-160 ~ 170 ℃ isikhathi eside. Emkhiqizweni we-monocrystalline silico, uphawu oluvame ukusetshenziswa lwe-fluorooelastomer ukubeka uphawu lokushisa okuphezulu (300 ℃) ngaphansi kwabezindaba ezikhethekile - i-trichlorohydrosilicon, i-siliclorohyrositon, i-sallium trichloride, i-fonium trichloride, i-trichlorethylene, ne-hydrorethylene, ne-hydrorsoric acid 120 ℃.

Kuzinhlelo zokusebenza ze-vacuum ephezulu, lapho ukushesha kwendiza ka-200 ~ 300km, umfutho womoya ngu-133 × 10-6 pa (10-6mmhg), i-chloroprene rubber, i-butyl ruble, irovu ye-buty Lapho indiza yokuphakama kwezinga ngaphezulu kuka-643km, umfutho womoya uzoncishiswa waba yi-133 × 10-7PA (10-7mmhg) okulandelayo, ama-fluorooelastomers kuphela angafakwa kule vacuum ephezulu. Ngokuvamile ohlelweni lwedivayisi ye-vacuum ephezulu noma ye-vacuum ephezulu kakhulu ngaphambi kokusetshenziswa, kudingeka ukuthi udlule ekwelashweni okushisa okuphezulu, uhlobo lwe-26-Type, u-fluoroolastomer olungama-246 angakwazi ukumelana nemishini enjoloba ebaluleke kakhulu emishini ephezulu ye-vacuum kanye nezimoto ze-cosmic.

I-hose eyenziwe nge-fluorooelastomer ilungele izinga lokushisa eliphakeme, amafutha nezindlela zokuxhumana ezikhethekile, njengamafutha okushisa endiza, i-aydgarbons eshisayo, owesilisa oshisayo kanye neminye imidiya ekhethekile (enjengezinye izindlela ezikhethekile (ezinjengezinye izihlokwana) zezokuthutha, ukuholwa njalonjalo. Yenziwe ngocingo lwe-fluorooelastomer kanye nekhebula eliguqukayo, nokufakelwa okuhle. I-fiber fiber tap eyenziwe nge-fluorooelastomer ingamelana nokushisa okuphezulu kwama-300 ℃ nokugqwala kwamakhemikhali. Indwangu e-Aramid ehlanganiswe ne-fluoroolastomer, ingenziwa ezitshalweni ze-petrochemical, amathangi aphezulu okushisa, i-acid kanye nama-alkali ekilasini phakathi kokukhishwa kwensimbi), nokuwohloka okuphezulu, nokuwohloka okuphezulu kwendima yokuhlaselwa kwamathangi okushaqeka. Indwangu ye-nylon ehlanganiswe nerabha ye-fluorine eyenziwe ngesikhwama se-tape sealing, njengendawo yokuhlanza ngaphakathi kwamathangi esitoreji sophahla oluntantayo ngezimpawu ezithambile zophahla ezintantayo ezinezimpawu ezithambile, dlala indima ekunciphiseni ukulahleka komoya.

Uhlobo 23, i-tetrapropyll Fluorine irabha isetshenziswa ikakhulukazi njenge-acid-searing, izikhathi zokubekwa uphawu ezilonakalisayo zamakhemikhali akhethekile. I-Hydroxy nitrosofluoromer isetshenziswa ikakhulukazi njengemikhiqizo evikelayo nemikhiqizo yokubopha, ngendlela yesisombululo njenge-coatible ehlanganayo, isetshenziswa ezingxenyeni ezivimbela umlilo nezingxenye ezisebenza ku-oksijini emhlophe. Isixazululo saso kanye nerabha eliwuketshezi kungafafazwa, kusakaze nezinye izindlela ukwenza imikhiqizo eminingi, njengezingubo ze-cosmic, amagilavu, amabhendi wepayipi, amabhola nokunye. Ingasetshenziswa futhi njengengilazi, insimbi, indwangu yomzimba, ukunamathela kwendwangu, ukukhiqizwa kwezipayisi zipayisikele kanye nokuxhumana nama-gaskets we-rocket propellant (N2O4), 'O Izinhlobo zezimpawu nokunye.

Izimpawu zenziwe ngochungechunge lwe-G-Fluololastomer uchungechunge linokusebenza kokushisa okushisa okushisa okushisa, uphethiloli we-methanol noma ukuphakama okuphezulu kwe-hydrocarboron angeke kufinyelelwe ngokusebenzisa i-vitona, b, e namanye ama-fluorooelastomers; Ama-fluoroolastomers we-GLT-Type, phosphorus chergeded rubber, njll. I-rubber ye-vompluohoohoohoohoohoohoohoohoohoohoohoohoohoohoohoohoohooroohooroohooroohoohoohororion inokumelana nokugqwala okuvelele kwabezindaba, okusetshenziswa kabanzi kubuchwepheshe obunqenqemeni bomkhakha wamasosha.
