Iingenelo
Ukusebenza kokutywinwa okuphezulu phantsi koxinzelelo oluphantsi
Ayifanelekanga ukutywinwa ibenye
Ufakelo olulula
Iipropati ze-polyurethane seals
1. Ukusebenza kokutywinwa
Isitywina se-polyurethane sinesiphumo esihle sobungqina bothuli, akulula ukuhlaselwa zizinto zangaphandle, kwaye zithintela ukuphazamiseka kwangaphandle, nokuba umphezulu uncangathi kwaye izinto zangaphandle ziyakwazi ukuchithwa.
2. Ukusebenza kwefriction
Ukumelana nokunxiba okuphezulu kunye nokuchasana okunamandla kwe-extrusion.Isitywina se-polyurethane sinokuhamba emva nangaphezulu ngesantya se-0.05m / s ngaphandle kokuthambisa okanye kwindawo yoxinzelelo lwe-10Mpa.
3. Ukumelana neoli elungileyo
Iitywina zePolyurethane aziyi konakala nokuba kujongwe i-kerosene, i-petroli kunye nezinye izibaso okanye ii-oyile ezinomatshini ezifana ne-hydraulic oil, i-oyile ye-injini kunye ne-oyile yokuthambisa.
4. Ubomi benkonzo ende
Ngaphantsi kweemeko ezifanayo, ubomi benkonzo ye-polyurethane seals ngamaxesha angama-50 ngaphezu kweempawu ze-NBR.Iimpawu zePolyurethane ziphezulu ngakumbi malunga nokumelana nokunxiba, amandla kunye nokumelana nokukrazula.
