Zvinhu zvikuru zverubber kuwedzera kubatanandezvi: silica gel, nitrile rabha, neoprene,EPDM rabha, natural rabha, fluoro rabha nemamwe rabha.
Zvimiro zvemuviri zvinoratidzwa nekupokana nemafuta, asidhi, alkali, abrasion, yakakwirira uye yakaderera tembiricha.
1. Natural rabha:
Synthetic rabha majoini ane yakakwira elasticity, yakakwirira elongation simba, yakanaka kupfeka kuramba uye kusanaya kwemvura, uye anogona kushandiswa patembiricha kubva -60 ℃ kusvika +80 ℃. Iyo yepakati inogona kuva mvura uye gasi.
2. Butyl rabha:
kupfeka-resistant rabha majoini anoshandiswa muguruva pombi uye jecha masisitimu. Iyo isingapfeki uye inodzivirira corrosion-resistant rubber joint inyanzvi yerabha yejoint yakanyatsogadzirirwa desulfurization systems. Iyo ine yakanaka kupfeka kuramba, asidhi uye alkali kuramba, corrosion kuramba, uye inogona kunyatso kutsiva iyo axial kuwedzera, radial kuwedzera, angular displacement uye mamwe mabasa edesulfurization mapaipi.
3. Chloroprene rabha (CR):
Mvura yegungwa inodzivirira rubber joint, ine yakanakisa oksijeni uye ozone kuramba, saka kuramba kwayo kuchembera kwakanyanya kunaka. Kushanda tembiricha renji: ingangoita -45 ℃ kusvika +100 ℃, nemvura yegungwa senzira huru.
4. Nitrile rabha (NBR):
Oil resistant rubber joint. Chimiro chakanaka kupikisa peturu. Kushanda tembiricha renji: anenge -30 ℃ kusvika +100 ℃. Chigadzirwa chinoenderana ndeichi: mafuta anodzivirira rubber joint, ine tsvina seyepakati.
5. Ethylene propylene diene monomer (EPDM):
Acid uye alkali resistant rabha majoini anowanzo shandiswa, anoratidzirwa neasidhi uye alkali kuramba, ane tembiricha inokwana -30 ℃ kusvika+150 ℃. Chigadzirwa chinoenderana: asidhi uye alkali inodzivirira rubber joint, yepakati itsvina.
Fluorine rabha (FPM) yakakwira-tembiricha inodzivirira rabha rabha yakabatanidzwa yezvekurima system elastomer inoumbwa necopolymerization yefluorine ine monomers. Chimiro chayo ndechepamusoro tembiricha kuramba kusvika 300 ℃.
Classification uye maitiro ekuita
Panyaya yekushandiswa, kune marudzi matatu eEPDM rubber (inonyanya kudiwa pakudzivirira mvura, mhute yemvura, uye kuchembera kukwegura), rubber yakasikwa (inonyanya kushandiswa kune rabha inongoda elasticity), butyl rubber (rubber inoda kuiswa chisimbiso chakanaka. ), nitrile rabha (rabha inoda kuramba mafuta), uye silicone (rabha yegiredhi rekudya);
Kuisa chisimbiso rabha inoshandiswa zvakanyanya mumaindasitiri akadai seantistatic, flame retardant, zvemagetsi, makemikari, mishonga, uye chikafu.
Zvishandiso zvemajoini erabha zvakakamurwa kuva mhando dzakasiyana zvichienderana nepakati inoshandiswa, senge chloroprene rabha, butyl rabha, fluororubber, EPDM rabha, uye rabha rechisikigo. Flexible rabha majoini anoshandiswa zvakanyanya mumhando dzakasiyana dzemapombi ekubatanidza, ane maitiro ekuita ekuvhunduka kubatwa, kuderedza ruzha, uye kudzoreredza muripo.
Basa remajoini erubha rinosiyana zvichienderana nezvinhu zvakashandiswa. Kusiyanisa kwekuita kunosanganisirawo yakakosha fluororubber uye silicone rabha, ine kusapfeka, kumanikidza kuramba, uye yakakwirira tembiricha kuramba. Iine mafuta anopikisa, acid uye alkali resistance, kutonhora uye kupisa kupisa, kuchembera kukwegura, nezvimwewo. Mukutaura kwekugadzirisa, rubber inogona kuitwa mumhando dzakasiyana-siyana dzekuwedzera kwerabha.
