Polyurethane Pulley (Polyurethane Lagging Pulley)

Elastomer na polyurethane da aka haɗe zuwa saman drum wani sabon abu ne na polymer roba tsakanin roba da filastik, wanda ke da ƙarfi da ƙarfi da ƙarfin filastik da roba.

Yana da halaye kamar haka:

1.Wide taurin iyaka. Har yanzu yana da elongation da juriya na roba a ƙarƙashin babban taurin. Kewayon taurin polyurethane elastomer shine Shore A10-D80.
2.High ƙarfi. Karfinsu na karyewa da iya daukar nauyinsu ya fi na roba na duniya a karkashin irin taurinsu. A babban taurin, ƙarfin tasirinsa da ƙarfin lanƙwasa ya fi filastik.
3.The lalacewa juriya ne sosai fice, kullum a cikin kewayon 0.01-0.10 (cm3) / 1.61km, game da 3-5 sau na roba.
4.Excellent mai juriya. Polyurethane elastomer wani nau'i ne na fili mai ƙarfi na polar polar, yana da ɗan kusanci da man ma'adinai mara iyaka, kuma kusan ba ya lalacewa a cikin man fetur da man inji.
5. Kyakkyawan iskar oxygen da juriya na ozone.
6. Kyakkyawan aikin ɗaukar rawar jiki, tare da raguwar girgiza, tasirin buffer.
7. Kyakkyawan ƙarancin zafin jiki.
