Polyurethane Pulley(Polyurethane Lagging Pulley)

Pulley Polyurethane (Pulley Lagging Polyurethane)

Tha polyurethane Pulley còmhdaichte le tiugh sònraichte de polyurethane air uachdar an druma stàilinn. Tha cruas àrd aig polyurethane, strì an aghaidh sgrìobadh, strì an aghaidh ola, strì an aghaidh oxidation agus feartan eile.

Tuairisgeul mionaideach

 

Tha an elastomer polyurethane a tha ceangailte ri uachdar an druma na stuth ùr polymer synthetigeach eadar rubair agus plastaig, aig a bheil an dà chuid neart àrd agus elasticity plastaig agus rubair.

Tha na feartan a leanas aige:

Raon cruas 1.Wide. Tha e fhathast a 'leudachadh agus tapaidh rubair fo àrd cruas. Is e an raon cruas de elastomer polyurethane Shore A10-D80.
2.High neart. tha an neart brisidh agus an comas giùlain mòran nas àirde na an rubair uile-choitcheann fon aon chruas. Le cruas àrd, tha a neart buaidh agus neart cromadh mòran nas àirde na plastaig.
3.Tha an aghaidh caitheamh gu math sònraichte, sa chumantas anns an raon 0.01-0.10 (cm3) /1.61km, mu 3-5 tursan de rubair.
4.Excellent ola an aghaidh. Tha elastomer polyurethane na sheòrsa de stuth làidir polar polymer, chan eil mòran dàimh aige ri ola mèinnearach neo-phòla, agus cha mhòr nach eil e air a chreachadh ann an ola connaidh agus ola meacanaigeach.
5. Deagh oxidation agus strì an aghaidh ozone.
6. Coileanadh sùghaidh crathaidh sàr-mhath, le lughdachadh crith, buaidh bufair.
7. Coileanadh math aig teòthachd ìosal.
