Izinto eziphambili zeirabha yokwandiswa ngokubambisanazezi: ijeli yesilika, irabha yenitrile, neoprene,Irabha ye-EPDM, irabha yendalo, irabha ye-fluoro kunye nezinye irabha.
Iimpawu ezibonakalayo zibonakaliswa ngokuchasana neoli, i-asidi, i-alkali, i-abrasion, iqondo lokushisa eliphezulu neliphantsi.
1. Irabha yendalo:
Amalungu erabha enziweyo anokwaluka okuphezulu, ukomelela okuphakamileyo obude, ukuxhathisa okulungileyo kokunxitywa kunye nokumelana nembalela, kwaye anokusetyenziswa kumaqondo obushushu ukusuka ku -60 ℃ ukuya +80 ℃. Isiphakathi singamanzi kunye negesi.
2. Irabha ye-butyl:
iindawo zerabha ezixhathisayo zisetyenziswa kwimibhobho yothuli kunye neenkqubo zesanti. Umdibaniso werabha okwaziyo ukumelana nokunxitywa kunye ne-corrosion-resistant yirabha edibeneyo yobuchwephesha eyenzelwe ngokukodwa iinkqubo ze-desulfurization. Inokumelana nokunxiba kakuhle, ukuxhathisa kwe-asidi kunye ne-alkali, ukuxhathisa ukubola, kwaye inokuhlawula ngokufanelekileyo ukwanda kwe-axial, ukwandiswa kwe-radial, ukufuduka kwe-angular kunye neminye imisebenzi ye-desulfurization pipelines.
3. Irabha yeChloroprene (CR):
Ijoyini yerabha ekwaziyo ukumelana namanzi olwandle, eneoksijini egqwesileyo kunye nokumelana ne-ozone, ke ngoko ukumelana kwayo ukwaluphala kulungile. Uluhlu lobushushu obusebenzayo: malunga -45 ℃ ukuya+100 ℃, ngamanzi olwandle njengowona mthombo uphambili.
4. Irabha yeNitrile (NBR):
I-oil resistant rubber joint. Uphawu lunokumelana kakuhle nepetroli. Uluhlu lobushushu obusebenzayo: malunga -30 ℃ ukuya +100 ℃. Imveliso ehambelanayo yile: i-oil resistant rubber joint, kunye ne-sewege njengento ephakathi.
5. I-Ethylene propylene diene monomer (EPDM):
Amalungu erabha axhathisa iasidi kunye nealkali aqhele ukusetyenziswa, aphawulwa ngokuxhathisa kweasidi kunye nealkali, kunye noluhlu lobushushu obumalunga -30 ℃ ukuya+150 ℃. Imveliso ehambelanayo: i-asidi kunye ne-alkali exhathisa irabha edibeneyo, i-medium yi-lindle.
Irabha yeFluorine (FPM) irabha edibeneyo yobushushu obuphezulu yokumelana nerabha yinkqubo yemveliso yezolimo i-elastomer eyenziwe yi-copolymerization yefluorine equlethe iimonomers. Uphawu lwayo kukumelana nobushushu obuphezulu ukuya kuthi ga kwi-300 ℃.
Ukuhlelwa kunye neempawu zokusebenza
Ngokumalunga nokusetyenziswa, kukho iintlobo ezintathu zerabha ye-EPDM (ikakhulukazi efunekayo ekuxhathiseni kwamanzi, ukuxhathisa umphunga wamanzi, kunye nokumelana nokuguga), i-rubber yendalo (ikakhulukazi isetyenziselwa i-rubber efuna kuphela u-elasticity), i-butyl irabha (i-rubber efuna ukusebenza kakuhle kokutywinwa). ), irabha ye-nitrile (i-rubber efuna ukuxhathisa ioli), kunye ne-silicone (i-rubber yebakala lokutya);
Irabha yokutywina isetyenziswa kakhulu kumashishini afana ne-antistatic, i-flame retardant, i-electronics, ikhemikhali, amayeza kunye nokutya.
Izinto ezidibeneyo zerabha zohlulwe zibe ziindidi ezahlukahlukeneyo ngokubhekiselele kwindlela esetyenziswa ngayo, njenge-rubber ye-chloroprene, i-rubber ye-butyl, i-fluororubber, i-EPDM irabha, kunye ne-rubber yendalo. Amalungu erabha athambileyo asetyenziswa ngokubanzi kuqhagamshelo lwemibhobho eyahlukeneyo, eneempawu zokusebenza zokufunxa ukothuka, ukunciphisa ingxolo, kunye nembuyekezo yokufuduswa.
Umsebenzi wamalungu e-rubber uyahluka ngokuxhomekeke kwizinto ezisetyenzisiweyo. Ukwahlula kwentsebenzo kukwabandakanya irabha ekhethekileyo ye-fluororubber kunye ne-silicone, enokumelana nokunxiba, ukumelana noxinzelelo, kunye nokumelana nobushushu obuphezulu. Inokumelana ne-oyile, i-asidi kunye nokumelana ne-alkali, ukumelana nokubanda kunye nokushisa, ukuguga, njl njl. Ngokubhekiselele kwi-customization, i-rubber ingenziwa kwiindidi ezahlukeneyo zokwandiswa kwerabha.
