Ukukhethwa kweImathiriyeli yokutywinas:
Eyona isetyenziswayo izinto zokutywinakwinkampani yethu iPolyurethane, irabha yeNitrile, iFluororubber, PTFE, njl., kunye nezixhobo ezahlukeneyo zineempawu ezahlukeneyo, ngolu hlobo lulandelayo:
(1) Imathiriyeli yepolyurethane inokumelana nokunxiba kakuhle kunye nesantya esincinci sokunyanzeliswa koxinzelelo, kwaye isetyenziswa ngokubanzi kumaxesha okutywinwa okuguquguqukayo.Iyakwazi ukumelana nobushushu obusebenzayo be--35-100 ℃, kwaye ifanelekile kwi-oyile ye-hydraulic esekelwe kwi-petroleum.Ngaphandle kwezinto ezithunyelwa ngaphandle, inokumelana ne-hydrolysis embi kwaye ayinakusetyenziselwa ioli ye-hydraulic esekelwe emanzini, njenge-glycol yamanzi.
(2) Imathiriyeli yerabha ye-Nitrile inokumelana nokunganxibi kakuhle, kwaye isetyenziswa ngokubanzi kwiindawo zokutywina ezimile, okanye zidityaniswe nezinye izinto ezikwaziyo ukunxiba ukuze zenze amakhonkco okutywina aguqukayo, afana namakhonkco e-Glyd kunye ne-Step seal.Iyakwazi ukumelana nobushushu obusebenzayo be -10-80 ℃, kwaye ihambelana kakuhle neoyile ezahlukeneyo zehydraulic ngaphandle kwephosphate ester.
(3) Isixhobo se-fluororubber sinokumelana okungahambi kakuhle kunye nobuchule bokuchasana nokukhupha.Ngokuqhelekileyo isetyenziswa kwiindawo zokutywina ezimileyo, okanye zidityaniswe nezinye izinto ezinganxiliyo ukwenza umsesane wokutywina oguqukayo.Xa isetyenziselwa ukutywina okuguquguqukayo kuphela, umsesane owugcinayo kufuneka wongezwe ukuthintela ukuphuma ngaphandle.Iyakwazi ukumelana nobushushu bokusebenza kwe--20-160 °C, kwaye inokusebenza kwindawo yobushushu obuphezulu be-200 °C ixesha elifutshane, kwaye ihambelana kakuhle neoli ehlukeneyo ye-hydraulic.
(4) Izinto ze-PTFE zinokumelana nokunxiba kakuhle kunye nokukwazi ukuchasana nokukhupha.Ngokuqhelekileyo isetyenziselwa ukudibanisa kunye nezinto zerabha ukwenza itywina eliguquguqukayo.Nangona kunjalo, ngenxa yesantya sayo esikhulu soxinzelelo, inokubangela ukuvuza okukhulu xa isetyenziswe kuxinzelelo oluphantsi.Ngokubanzi isetyenziswa kwindawo yobushushu obuphezulu obungaphezulu kwe-25MPa.Iyakwazi ukumelana nobushushu obusebenzayo be--40-135 ℃, kwaye ihambelana kakuhle neeoli ezahlukeneyo zehydraulic.
