I-Stainless Steel Rubber Bellows Expansion Joints Rubber EPDM

Incazelo Yomkhiqizo

Amalunga okunweba enjoloba abizwa nangokuthi amajoyinti enjoloba, amalunga enjoloba aguquguqukayo, isinxephezelo senjoloba esiguquguqukayo, ama-absorber shock, ama-rubber shock absorbers, njll. Umkhiqizo uqukethe ingxenye yenjoloba eyishubhu eyakhiwe izingqimba zenjoloba zangaphakathi nangaphandle, izendlalelo zendwangu yentambo kanye nezinsimbi zocingo, okuyinto. ivuvukala ekushiseni okuphezulu kanye nokucindezela okuphezulu bese ihlanganiswa ne-flange yensimbi noma umkhono oxekethile welunga elihambisanayo. Inganciphisa ukudlidliza nomsindo ngenxa yokunwebeka okuphezulu, ukungena komoya okuphezulu, ukumelana nendawo, ukumelana nesimo sezulu kanye nokumelana nemisebe yenjoloba, futhi inganxephezela ukwanda okushisayo nokufinyela okubandayo okubangelwa ukushintsha kwezinga lokushisa. Isetshenziswa kabanzi ezinhlelweni zamapayipi ahlukahlukene.

Isici:

Inomthamo omkhulu wangaphakathi, ingakwazi ukumelana nokucindezela okuphezulu, futhi inomphumela omuhle wokuguga nokunwebeka.

Inzuzo:

Yehlisa ukudlidliza, umsindo nokukhanya.

Inhloso:

Ukuxhumana namaphampu, amavalvu kanye nemishini yokucisha umlilo, amapayipi anokunyakaza okukhulu, namapayipi anezinguquko ezivamile emakhazeni nasekushiseni.

Imidiya esebenzayo:

Amanzi olwandle, amanzi ahlanzekile, amanzi abandayo nashisayo, amanzi okuphuza, indle yasendlini, uwoyela ongahluziwe, uwoyela wokubasa, uwoyela wokugcoba, uwoyela womkhiqizo, umoya, igesi, isitimu kanye nompushana oyimbudumbudu.

Imodi yokuxhuma:

Ngokuvamile, uhlobo lwe-flange oluxekethile (i-semi seal), uhlobo lwe-flange olungaguquki (uphawu olugcwele), uhlobo lwe-clamp noxhumo olunentambo kuyatholakala.

Impahla ye-rubber flexible joint:

Irabhaukujoyina okuguquguqukayoibhola lakhiwe ngeshubhu yenjoloba enezingqimba eziningi zendwangu yentambo enayiloni eklwelwe ngenjoloba kanye nongqimba lwenjoloba lwangaphandle kungqimba lwenjoloba yangaphakathi kanye nongqimba oluqinisayo. Izinto zenjoloba ezisetshenziswayo zihlukile ngokuya ngemidiya ehlukene, okuhlanganisa irabha yemvelo, irabha ye-styrene butadiene, irabha ye-butyl, irabha ye-nitrile, i-ethylene propylene diene monomer, irabha ye-neoprene, irabha ye-silicone, irabha ye-fluorine, njll. Inemisebenzi yokumelana nokushisa, i-asidi ukumelana, ukumelana ne-alkali, ukumelana nokugqwala, ukumelana nemihuzuko, ukumelana nowoyela, njll.

Izigaba ezithile zamalunga enjoloba aguquguqukayo yilezi: Ijoyinti lerabha eliphikisayo eliphikisayo, ijoyinti lerabha elimelana ne-asidi ne-alkali, ijoyinti lerabha elimelana nowoyela, ijoyinti lerabha elimelana nokushisa okuphezulu, ikhanda lenjoloba elingagugi.

Ukufakwa kwejoyinti eliguquguqukayo lerabha:

Amajoyinti okwandisa irabha asetshenziswa kakhulu ekushiseni kwamanzi kanyeukufakwawamapayipi okuphefumula komoya emvelo, ukuphakelwa kwamanzi kanye nokukhipha amanzi kanye namapayipi amanzi ajikelezayo, amapayipi esiqandisi, amapayipi anqanda ukugqwala, ukulwa nomlilo kanye namapayipi okucindezela ifriji, kanye nasemalabhorethri, izikhungo zocwaningo lwesayensi, imikhumbi, imikhumbi kanye namanye amaphrojekthi wobunjiniyela bamapayipi ukunciphisa ukudlidliza. kanye nomsindo, i-offset nezinye izindlela zokunakekela nokuphatha. Ipayipi kufanele limiswe ngokuzinza ohlelweni lokuphakelwa kwamanzi omoya kanye nohlelo lokudonsa amanzi endaweni ehlangene yamabhola erabha aphindwe kabili kusekelo, isekelo noma ifremu lehange.

Izici eziyinhloko zejoyinti lokunwetshwa kwenjoloba ye-EPDM

1. Ukumelana nokuguga:Ukuhlanganiswa kwerabha ye-EPDMinokumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana nokushisa, ukumelana ne-asidi ne-alkali, ukumelana nomhwamuko wamanzi, ukuzinza kombala, ukusebenza kukagesi, ukugcwaliswa kwamafutha kanye noketshezi lokushisa kwegumbi.

2. Ukumelana nokushisa okuphezulu: I-EPDM yenjoloba ehlangene ingasetshenziswa isikhathi eside ku-120 ℃, futhi ingasetshenziswa isikhashana noma ngezikhathi ezithile ku-150 - 200 ℃. Inokumelana kahle nomhwamuko wamanzi futhi kulinganiselwa ukuthi ingaphezu kokumelana nokushisa kwayo.

3. Ukumelana nokugqwala: ngenxa yokuntuleka kwe-polarity kanye nokungatholakali kwe-unsaturation ephansi yerabha ye-ethylene propylene emajoyini enjoloba e-EPDM, inokumelana kahle namakhemikhali ahlukahlukene e-polar njengotshwala, i-asidi, i-alkali, i-oxidant, isiqandisi, okokuhlanza, amafutha ezilwane nemifino, i-ketone namafutha.

4. Ukunwebeka okuhle: Ijoyinti yerabha ye-EPDM inwebeka kakhulu kunejoyinti yenjoloba yemvelo.

Uxhumano oluthambile lwe-EPDM lwenjoloba lungafinyelela ku-150h ngaphandle kokuphuka ngaphansi kwesimo se-ozone engu-50 phm kanye nokwelula okungu-30%, ngokumelana nesimo sezulu (ukusetshenziswa kwebanga lokushisa - 40 ℃ - 150 ℃) nokumelana namakhemikhali. Ngemva kokwengeza i-retardant flame, iba ne-flame retardancy enhle kanye ne-flame retadancy. Umkhiqizo ucutshungulwa yi-microwave eqhubekayo yokwenza i-vulcanization kanye, enendawo ebushelelezi futhi enhle, ukusebenza okuzinzile(futhi akulula ukukushintsha.
