(Incazelo efingqiwe)I-fluoroelastomer iyi-copolymer ye-vinyl fluoride ne-hexafluoropropylene. Ngokuya ngesakhiwo sayo samangqamuzana nokuqukethwe kwe-fluorine, ama-fluoroelastomers anokumelana namakhemikhali ahlukene kanye nokumelana nezinga lokushisa eliphansi.
I-fluoroelastomer iyi-copolymer ye-vinyl fluoride ne-hexafluoropropylene. Ngokuya ngesakhiwo sayo samangqamuzana nokuqukethwe kwe-fluorine, ama-fluoroelastomers anokumelana namakhemikhali ahlukene kanye nokumelana nezinga lokushisa eliphansi. I-Fluoroelastomer isekelwe ekubambeni kwayo ilangabi okuhle kakhulu, ukuqina komoya okuhle kakhulu, ukumelana nokushisa okuphezulu, ukumelana ne-ozone, ukumelana nesimo sezulu, ukumelana ne-oxidation, ukumelana nowoyela wamaminerali, ukumelana nowoyela kaphethiloli, ukumelana nowoyela we-hydraulic, ukumelana nephunga elimnandi kanye nezinyibilikisi eziningi eziphilayo Ezaziwa ngezakhiwo zamakhemikhali.
Izinga lokushisa elisebenzayo ngaphansi kokuvalwa kwe-static lilinganiselwe phakathi kuka--26°C no-282°C. Nakuba ingasetshenziswa ngesikhathi esifushane ezingeni lokushisa elingu-295°C, impilo yayo yesevisi izofinyezwa lapho izinga lokushisa lidlula ku-282°C. Izinga lokushisa elifanele kakhulu elingasetshenziswa ngaphansi kwe-dynamic seal liphakathi kuka--15℃ no-280℃, futhi izinga lokushisa eliphansi lingafinyelela ku--40℃.
Ukusebenza kwendandatho yokuvalwa kwerabha ye-fluorine
(1) Egcwele ukuguquguquka nokukhuthazela;
(2) Amandla afanele emishini, okuhlanganisa amandla okunweba, ubude nokumelana nezinyembezi.
(3) Ukusebenza kuzinzile, akulula ukuvuvukala phakathi nendawo, futhi umphumela wokunciphisa okushisayo (umphumela we-Joule) mncane.
(4) Kulula ukuyicubungula futhi ilolonge, futhi ingagcina ubukhulu obunembe.
(5) Ayigqwali indawo yokuxhumana, ayingcolisi okuphakathi, njll.
Izinzuzo zendandatho yokuvala irabha ye-fluorine
1. Indandatho yokuvala kufanele ibe nokusebenza okuhle kokuvala ngaphakathi kwengcindezi yokusebenza kanye nebanga elithile lokushisa, futhi ingathuthukisa ngokuzenzakalelayo ukusebenza kokuvala njengoba ingcindezi ikhula.
2. Ukungqubuzana phakathi kwensimbi yokuvala uphawu kanye nezingxenye ezihambayo kufanele kube kuncane, futhi i-coefficient ye-friction kufanele izinzile.
3. Indandatho yokuvala inokumelana nokugqwala okuqinile, akulula ukuguga, impilo ende yokusebenza, ukumelana nokugqokwa okuhle, futhi inganxephezela ngokuzenzekelayo ngezinga elithile ngemva kokugqoka.
4. Isakhiwo esilula, kulula ukuyisebenzisa futhi silondoloze indandatho yokubeka uphawu, yiziphi izinzuzo zendandatho yokuvala irabha ye-fluorine ukwenza indandatho yokuvala ibe nempilo ende.
Idizayini ye-O-ring inquma ukusetshenziswa komkhiqizo
Indandatho yokuvala emise okuka-O ifaneleka ukufakwa ezintweni ezisetshenziswayo ezihlukahlukene, futhi idlala indima yokuvala esimweni esimile noma esinyakazayo ezingeni lokushisa elithile, ingcindezi, kanye nemidiya ehlukene yoketshezi negesi. Izinhlobo ezahlukahlukene zezimpawu zisetshenziswa kakhulu kumathuluzi omshini, imikhumbi, izimoto, imishini ye-aerospace, imishini yensimbi, imishini yamakhemikhali, imishini yobunjiniyela, imishini yokwakha, imishini yezimayini, imishini ye-petroleum, imishini yepulasitiki, imishini yezolimo, nezinsimbi ezahlukahlukene namamitha. isici.
