1. Irabha yendalo (NR)
Ubukhulu becala yirabha hydrocarbon (i-polyisoprene), equlethe isixa esincinci seprotheyini, amanzi, i-asidi ye-resin, iswekile kunye netyuwa ye-inorganic.I-elasticity enkulu, ukomelela okuphezulu, ukuxhathisa okugqwesileyo kokukrazula kunye nokufakelwa kombane, ukumelana nokunxiba kakuhle kunye nokumelana nembalela, ukuqhubekeka kakuhle, ukubotshwa ngokulula kunye nezinye izinto, kwaye zingcono kuneninzi iirubha ezenziweyo malunga nokusebenza okubanzi.Ukungalungi ukuchasana kakubi kwe-oksijeni kunye ne-ozone, kulula ukuguga kunye nokuwohloka;ukuxhathisa kakubikwi-oyile kunye ne-solvents, ukuxhathisa okuphantsi kwe-corrosion kwi-acids kunye ne-alkali, kunye nokumelana nokushisa okuphantsi.Uluhlu lobushushu obusebenzayo: malunga -60℃~+80℃.Ukuveliswa kwamatayara, izihlangu zerabha, imibhobho, iiteyiphu, iileyiti zokhuselo kunye neeshethi zeengcingo kunye neentambo, kunye nezinye ngokubanzi.iimveliso.Ifaneleke ngakumbi ukuveliswa kwe-torsional vibration eliminators, ii-absorber zothusa ii-injini, izixhaso zoomatshini, izinto zokuxhoma irabha-zentsimbi, i-diaphragms, kunye neemveliso ezibunjiweyo.
iimveliso zerabha
2. Irabha ye-styrene butadiene (SBR)
I-copolymer ye-butadiene kunye ne-styrene.Ukusebenza kusondele kuleyo yerabha yendalo.Yirabha yokwenziwa yenjongo ngokubanzi enemveliso enkulu ngoku.Ibonakala ngokuxhathisa i-abrasion, ukumelana nokuguga kunye nokumelana nokushisa okudlula irabha yendalo, kwaye ukuthungwa kwayo kufana kakhulu kunerubha yendalo.Izinto ezingeloncedo zezi: i-elasticity ephantsi, ukungaguquguquki okubi kunye nokumelana nokukrazula;ukusebenza kakubi, ngakumbi ukuzincamathela okungekuhle kunye namandla erabha eluhlaza.Ubushushu bokusebenzauluhlu lwendalo: malunga -50℃~＋100℃.Isetyenziswa ikakhulu endaweni yerabha yendalo ukwenza amatayara, amashiti erabha, imibhobho, izihlangu zerabha kunye nezinye iimveliso jikelele.
3. Irabha yeButadiene (BR)
Yirabha ye-cis-structure eyenziwe yi-polymerization ye-butadiene.Iingenelo zezi: ukuqina okugqwesileyo kunye nokunganyangeki, ukumelana nokuguga okuhle, ukumelana nobushushu obuphantsi, ubushushu obuphantsi besizukulwana phantsi komthwalo oguqukayo, kunye nokubotshwa kwentsimbi ngokulula.Tizinto ezingalunganga zinamandla aphantsi, ukunganyangeki kokukrazula, ukusebenza kakubi kokusebenza kunye nokuzincamathela.Uluhlu lobushushu obusebenzayo: malunga -60℃~＋100℃.Ngokubanzi, isetyenziswa kunye nerabha yendalo okanye irabha ye-styrene-butadiene, ikakhulu ukwenza itayara.ifundeka, amabhanti okuhambisa kunye neemveliso ezikhethekileyo ezikwaziyo ukumelana nokubanda.
4. Irabha ye-isoprene (IR)
Luhlobo lwerubha ye-cis eyenziwe nge-polymerization ye-isoprene monomer.Ukwakhiwa kweekhemikhali kunye ne-three-dimensional structure ifana nerubha yendalo, kwaye ukusebenza kusondele kakhulu kwirubha yendalo, ngoko kuthiwa yindalo yokwenziwa.irabha.Ininzi yeenzuzo zerabha yendalo.Ngenxa yokungagugi, irabha yendalo inokuqina okuncinci kunye namandla kunerabha yendalo, ukusebenza kakubi kunye neendleko eziphezulu.Uluhlu lobushushu obusebenzayo: malunga -50℃~+100℃Ingathatha indawo yerabha yendalo ukwenza amatayara, izihlangu zerabha, imibhobho, iiteyiphu kunye nezinye iimveliso eziqhelekileyo.
5. I-Neoprene (CR)
Yipolymer eyenziwe yi-emulsion polymerization ye-chloroprene njenge-monomer.Olu hlobo lwerabha luqulathe iiathom zeklorin kwimolekyuli yalo, ngoko ke xa kuthelekiswa nezinye iirubha ngokubanzi: ine-antioxidant egqwesileyo, ukumelana ne-ozone, ukungatsha, ukuzicima emva komlilo, ukunganyangeki kwe-oyile, ukuxhathisa kwe-solvent, i-asidi kunye nokumelana ne-alkali, ukuguga kunye negesi. ukuxhathisa.Ukuqina okuhle kunye nezinye iingenelo;iimpawu zayo zomzimba kunye noomatshini nazo zingcono kunerabha yendalo, ngoko inokusetyenziswa njengerabha yenjongo jikelele okanye irabha ekhethekileyo.Izinto ezingeloncedo eziphambili kukunganyangeki kakuhle kwengqele, umxhuzulane omkhulu okhethekileyo, ixabiso eliphezulu elinxulumene nombane, ukugquma kombane, kunye nokuncamathela lula, ukutshisa, kunye nokuncamathela komngundo ngexesha lokulungiswa.Ukongeza, irabha eluhlaza ine-stabi embikwaye akukho lula ukuyigcina.Uluhlu lobushushu obusebenzayo: malunga -45℃~＋100℃.Ikakhulu isetyenziselwa ukwenza i-cable sheaths kunye nezigqubuthelo ezahlukeneyo zokhuselo kunye nezikhuselo ezifuna ukuxhathisa okuphezulu kwe-ozone kunye nokumelana nokuguga okuphezulu;ioli kunye nekhemikhali ukumelanaimibhobho ye-ance, iiteyiphu kunye nemigca yeekhemikhali;iimveliso zerabha ezimelana nomlilo kwimigodi engaphantsi komhlaba, kunye neentlobo ezahlukeneyo zokubumba Iimveliso, imisesane yokutywina, iigaskets, izinto zokuncamathelisa, njl.
