Izinto eziyinhloko zeukuhlanganiswa kwenjoloba yokwandisayilezi: ijeli ye-silica, irabha ye-nitrile, i-neoprene, irabha ye-EPDM, irabha yemvelo, irabha ye-fluoro kanye nenye irabha.
Izakhiwo zomzimba zibonakala ngokumelana namafutha, i-asidi, i-alkali, i-abrasion, izinga lokushisa eliphezulu neliphansi.
1. Irabha yemvelo
Amajoyinti enjoloba okwenziwa anokunwebeka okuphezulu, amandla okunwebeka okuphezulu, ukumelana kahle nokugqokwa kanye nokumelana nesomiso, futhi angasetshenziswa emazingeni okushisa asukela ku -60 ℃ kuya +80 ℃.Okuphakathi kungaba amanzi negesi.
2. Irabha ye-butyl
Amajoyinti enjoloba angagugi asetshenziswa kumapayipi othuli nasezinhlelweni zesihlabathi.Ijoyinti lerabha elingagugi kanye nelimelana nokugqwala liyijoyinti lerabha elichwepheshile elakhelwe ngokukhethekile amasistimu e-desulfurization.Inokumelana nokugqokwa okuhle, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, futhi inganxephezela ngempumelelo ukunwetshwa kwe-axial, ukunwetshwa kwe-radial, ukususwa kwe-angular kanye neminye imisebenzi yamapayipi e-desulfurization.
3. Irabha ye-Chloroprene (CR)
Ijoyinti lerabha elimelana namanzi olwandle, elinomoya-mpilo omuhle kakhulu nokumelana ne-ozone, ngakho-ke ukumelana kwalo nokuguga kuhle kakhulu.Izinga lokushisa elisebenzayo: cishe -45 ℃ ukuya +100 ℃, amanzi olwandle njengendlela eyinhloko.
4. Irabha ye-Nitrile (NBR)
Ijoyinti lerabha elimelana nowoyela.Isici siwukumelana kahle ne-oline yegesi.Ibanga lokushisa elisebenzayo: cishe -30 ℃ kuya +100 ℃.Umkhiqizo ohambisanayo yilokhu: ijoyinti lenjoloba elimelana nowoyela, elinendle njengendlela ephakathi.
5. I-Ethylene propylene diene monomer (EPDM)
Amalunga enjoloba amelana ne-asidi ne-alkali avame ukusetshenziswa, abonakala ngokumelana ne-asidi ne-alkali, ngezinga lokushisa elingaba ngu--30 ℃ kuya ku-+150 ℃.Umkhiqizo ohambisanayo: ijoyinti lenjoloba elimelana ne-asidi ne-alkali, okuphakathi yindle.
Irabha ye-fluorine (i-FPM) yerabha ehlangene yerabha ehlangene yokumelana nezinga lokushisa iwuhlelo lokukhiqiza lwezolimo lwe-elastomer olwakhiwe yi-copolymerization ye-fluorine equkethe ama-monomers.Isici sawo ukumelana nezinga lokushisa eliphezulu kuze kufike ku-300 ℃.
Ngaphezu kwalawo ashiwo ngenhla, kunamabizo ajwayelekile: 310 Heat Expansion Joint,I-Sleeve Expansion Joint
Izigaba nezici zokusebenza
Mayelana nokusetshenziswa, kunezinhlobo ezintathu zeIrabha ye-EPDM(ikakhulukazi edingekayo ekuphikisweni kwamanzi, ukumelana nomhwamuko, nokumelana nokuguga), irabha yemvelo (ikakhulukazi esetshenziselwa irabha edinga ukunwebeka), irabha ye-butyl (iraba edinga ukusebenza kahle kokuvala), irabha ye-nitrile (irabha edinga ukumelana nowoyela), kanye ne-silicone (irabha yebanga lokudla);
Irabha yokuvala uphawu isetshenziswa kakhulu ezimbonini ezifana ne-antistatic, i-flame retardant, electronics, chemical, pharmaceutical, kanye nokudla.
Izinto ezihlangene zenjoloba zihlukaniswe zaba izinhlobo ezihlukahlukene ngokusekelwe endaweni esetshenziswayo, njengerabha ye-chloroprene, irabha ye-butyl, irabha ye-fluoro, irabha ye-EPDM kanye nerabha yemvelo.Amajoyinti enjoloba aguqukayo asetshenziswa kakhulu ekuxhumekeni kwamapayipi ahlukahlukene, anezici zokusebenza zokumunca ukushaqeka, ukuncishiswa komsindo, nesinxephezelo sokufuduka.
Umsebenzi wamajoyinti enjoloba uyahluka kuye ngezinto ezisetshenzisiwe.Ukuhlukaniswa kokusebenza kufaka phakathi irabha ekhethekile ye-fluororubber ne-silicone, enokumelana nokugqoka, ukumelana nokucindezela, nokumelana nokushisa okuphezulu.Inokumelana nowoyela, ukumelana ne-asidi kanye ne-alkali, ukumelana nokubanda nokushisa, ukumelana nokuguga, njll. Ngokuphathelene nokwenza ngokwezifiso, irabha ingenziwa ibe izinhlobo ezihlukahlukene zokuhlanganiswa kwenjoloba yokwandisa.
