Ingcaciso yeMveliso

Ukwandiswa kwamalungu erabha kukwabizwa ngokuba ngamalungu erabha, amalungu erabha aguquguqukayo, i-rubber eguquguqukayo yerabha, i-absorbers yokothuka, i-rubber shock absorbers, njl. uvulcanized kubushushu obuphezulu kunye noxinzelelo oluphezulu kwaye emva koko kudityaniswe neflange yentsimbi okanye umkhono okhululekileyo wejoyinti enxuseneyo.Inokunciphisa ukungcangcazela kunye nengxolo ngenxa ye-elasticity ephezulu, ukunyanzeliswa komoya okuphezulu, ukuxhathisa okuphakathi, ukuxhathisa imozulu kunye nokuxhathisa irabha kwimitha, kwaye inokubuyisela ukwanda kwe-thermal kunye nokunciphisa okubandayo okubangelwa utshintsho lobushushu.Isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zemibhobho.

Uphawu:

Inoxinano oluphezulu lwangaphakathi, inokumelana noxinzelelo oluphezulu, kwaye inesiphumo esihle se-elastic deformation.

I-advanteji:

Nciphisa ukungcangcazela, ingxolo kunye nokukhaphukhaphu.

Injongo:

Ukudibanisa kunye neepompo, iivalve kunye nezixhobo zokulwa nomlilo, iibhobho ezinokugubha okukhulu, kunye nemibhobho enokutshintsha rhoqo kubanda kunye nobushushu.

Imidiya esebenzayo:

Amanzi olwandle, amanzi acocekileyo, abandayo nashushu, amanzi okusela, ilindle lasekhaya, i-oyile ekrwada, i-oyile yamafutha, i-oyile yokuthambisa, i-oyile yemveliso, umoya, igesi, umphunga kunye nomgubo wegranular.

Imo yoqhagamshelo:

Ngokuqhelekileyo, uhlobo lwe-flange olukhululekile (i-semi seal), uhlobo lwe-flange esisigxina (itywina eligcweleyo), uhlobo lwe-clamp kunye noqhagamshelwano lwentambo luyafumaneka.

Izinto zerabha eziguquguqukayo ngokudibeneyo:

Irabhai-flexible jointibhola yenziwe ityhubhu yerabha enemigangatho emininzi yerabha ekhutshiweyo yentambo yelaphu yenayiloni kunye nomaleko werabha ongaphandle kumqolo werabha ongaphakathi kunye nomaleko wokuqinisa.Izinto zerabha ezisetyenzisiweyo ziyahluka ngokwemidiya eyahlukeneyo, kubandakanywa irabha yendalo, irabha ye-styrene butadiene, irabha ye-butyl, irabha ye-nitrile, i-ethylene propylene diene monomer, irabha ye-neoprene, irabha ye-silicone, irabha ye-fluorine, njl. Inemisebenzi yokumelana nobushushu, i-asidi. ukumelana, ukuxhathisa kwe-alkali, ukuxhathisa ukubola, ukuxhathisa i-abrasion, ukumelana neoli, njl.

Ukuhlelwa okuthe ngqo kwamalungu aguquguqukayo erabha zezi: Ijoyinti yerabha echasene noxinzelelo olubi, i-asidi kunye ne-alkali ekwazi ukumelana nerabha, i-oyile ekwazi ukumelana nerabha, ijoyini yerabha ekwaziyo ukumelana nobushushu obuphezulu, intloko yerabha enganxibiyo.

Ufakelo lwerabha eguquguqukayo ngokudibeneyo:

Amalungu okwandisa iRubber asetyenziswa ngokubanzi ekufudumeni kwamanzi kunyeukufakelaimibhobho yendalo yokuphuma komoya, unikezelo lwamanzi kunye nokuhambisa amanzi kunye nokujikeleza kwemibhobho yamanzi, imibhobho yesikhenkcezisi, imibhobho yokunqanda ukubola, ukulwa nomlilo kunye nemibhobho yokufaka isikhenkcezisi sefriji, kunye nakwiilabhoratri, amaziko ophando lwenzululwazi, iinqanawa, iinqanawa kunye nezinye iiprojekthi zobunjineli bemibhobho ukunciphisa ukungcangcazela. kunye nengxolo, i-offset kunye nezinye iindlela zokugcina kunye nokulawula.Umbhobho uya kunqunyanyiswa ngokuzinzileyo kunikezelo lwamanzi lomoya kunye nenkqubo yokuhambisa amanzi kwirabha edibeneyo yebhola ephindwe kabini kwinkxaso, inkxaso okanye isakhelo se-ankile.

Iimpawu eziphambili ze-EPDM zokwandisa irabha edibeneyo

1. Ukuxhathisa ukwaluphala:I-EPDM yerabha edibeneyoinokumelana nemozulu ebalaseleyo, ukumelana ne-ozone, ukumelana nobushushu, ukuxhathisa kwe-asidi kunye ne-alkali, ukuxhathisa komphunga wamanzi, ukuzinza kombala, ukusebenza kombane, ukuzaliswa kweoli kunye nobushushu begumbi.

2. Ukumelana nokushisa okuphezulu: I-EPDM i-rubber joint ingasetyenziselwa ixesha elide kwi-120 ℃, kwaye ingasetyenziselwa ngokufutshane okanye ngokukhawuleza kwi-150 - 200 ℃.Inokumelana kakuhle nomphunga wamanzi kwaye kuqikelelwa ukuba iphezulu kunokumelana nobushushu.

3. Ukumelana ne-Corrosion: ngenxa yokungabikho kwe-polarity kunye ne-unsaturation ephantsi ye-ethylene propylene irabha kwi-rubber joints EPDM, inokumelana kakuhle neekhemikhali ezahlukeneyo ze-polar ezifana notywala, i-asidi, i-alkali, i-oxidant, i-friji, i-detergent, i-oyile yezilwanyana kunye nemifuno, i-ketone kunye negrisi.

4. I-elasticity enhle: I-EPDM i-rubber joint i-elastic ngaphezu kwe-rubber yendalo.

I-EPDM irabha uxhulumaniso oluthambileyo lunokufikelela kwi-150h ngaphandle kokuphulwa phantsi kwemeko ye-50 pphm yoxinaniso lwe-ozone kunye ne-30% yokwelula, kunye nokumelana nemozulu (ukusetyenziswa kweqondo lokushisa - 40 ℃ - 150 ℃) kunye nokuxhathisa imichiza.Emva kokongeza i-retardant yedangatye, inokunqanda idangatye elungileyo kunye nedangatye lokulibaziseka.Imveliso icutshungulwa yi microwave eqhubekayo vulcanization kanye, kunye nomphezulu ogudileyo kunye nobuhle, ukusebenza okuzinzileyo (kwaye akukho lula ukutshintsha.
