(Inkcazo yesishwankathelo)I-fluoroelastomer yi-copolymer ye-vinyl fluoride kunye ne-hexafluoropropylene. Ngokuxhomekeke kwisakhiwo sayo se-molecular kunye nomxholo we-fluorine, i-fluoroelastomers inokumelana neekhemikhali ezahlukeneyo kunye nokumelana nokushisa okuphantsi.
I-fluoroelastomer yi-copolymer ye-vinyl fluoride kunye ne-hexafluoropropylene. Ngokuxhomekeke kwisakhiwo sayo se-molecular kunye nomxholo we-fluorine, i-fluoroelastomers inokumelana neekhemikhali ezahlukeneyo kunye nokumelana nokushisa okuphantsi. I-Fluoroelastomer isekwe kwi-retardancy yayo ebalaseleyo yomlilo, ukuxinana komoya okugqwesileyo, ukumelana nobushushu obuphezulu, ukumelana ne-ozone, ukumelana nemozulu, ukuxhathisa kwe-oxidation, ukumelana ne-oyile yeminerali, ukuxhathisa kwe-oyile ye-oyile, ukuxhathisa kwe-oyile yehydraulic, ukumelana nevumba elimnandi kunye nezinyibilikisi ezininzi ze-organic Ezaziwa ngeempawu zayo zekhemikhali.
Ubushushu bokusebenza phantsi kotywino oluzinzileyo lulinganiselwe phakathi kwe -26°C kunye ne282°C. Nangona ingasetyenziswa ngexesha elifutshane kwiqondo lokushisa lama-295 ° C, ubomi bayo benkonzo buya kufinyezwa xa ubushushu budlula i-282 ° C. Obona bushushu bufanelekileyo bokusetyenziswa phantsi kwe-dynamic seal buphakathi kwe -15℃ kunye ne280℃, kwaye ubushushu obuphantsi bunokufikelela ku -40℃.
Fluorine irabha yokutywina ukusebenza komsesane
(1) Igcwele ukuguquguquka kunye nokomelela;
(2) Amandla afanelekileyo omatshini, kubandakanywa amandla okwandisa, ukunyusa kunye nokuxhathisa ukukrazula.
(3) Ukusebenza kuzinzile, akulula ukudumba phakathi, kunye nefuthe le-thermal contraction effect (i-Joule effect) incinci.
(4) Kulula ukusetyenzwa kunye nokubumba, kwaye inokugcina imilinganiselo echanekileyo.
(5) Ayingcolisi indawo yokudibanisa, ayingcolisi i-medium, njl.
Izinto eziluncedo zerubha yokutywina irabha ye-fluorine
1. Umsesane wokutywina kufuneka ube nokusebenza kakuhle kokutywinwa ngaphakathi koxinzelelo lokusebenza kunye noluhlu oluthile lobushushu, kwaye lunokuphucula ngokuzenzekelayo ukusebenza kokutywinwa njengoko uxinzelelo lukhula.
2. Ukungqubuzana phakathi kwesixhobo sokutywina kunye neendawo ezihambayo kufuneka zibe zincinci, kwaye i-coefficient ye-friction kufuneka izinzile.
3. Umsesane wokutywina unokumelana nokugqwala okuqinileyo, akukho lula ukuguga, ubomi obude bokusebenza, ukumelana nokunxiba kakuhle, kwaye unokuhlawula ngokuzenzekelayo umlinganiselo othile emva kokunxiba.
4. Isakhiwo esilula, kulula ukuyisebenzisa kunye nokugcina umsesane wokutywina, ziziphi iingenelo zeringi yokutywina yerubha ye-fluorine ukwenza umsesane wokutywina ube nobomi obude.
Uyilo lwe-O-ring lumisela ukusetyenziswa kwemveliso
Umsesane wokutywina owenziwe nge-O-ulungele ukufakwa kwizixhobo ezahlukeneyo zoomatshini, kwaye udlala indima yokutywina kwindawo engatshintshiyo okanye eshukumayo kwiqondo lobushushu elichaziweyo, uxinzelelo, kunye nolwelo olwahlukileyo kunye nemidiya yegesi. Iindidi ezahlukeneyo zamatywina zisetyenziswa ngokubanzi kwizixhobo zoomatshini, iinqanawa, iimoto, izixhobo ze-aerospace, oomatshini besinyithi, oomatshini beekhemikhali, oomatshini bobunjineli, oomatshini bokwakha, oomatshini bemigodi, oomatshini bepetroleum, oomatshini beplastiki, oomatshini bezolimo, kunye nezixhobo ezahlukeneyo kunye neemitha. isiqalelo.
