ʻO ka Pulley Polyurethane (Polyurethane Lagging Pulley)

ʻO ka polyurethane elastomer i hoʻopili ʻia i ka ʻili o ka pahu he mea synthetic polymer hou ma waena o ka pahu a me ka plastic, nona ka ikaika kiʻekiʻe a me ka elasticity o ka plastic a me ka rubber.

Loaʻa iā ia nā ʻano penei:

1.Wide ākea paʻakikī. Loaʻa iā ia ka elongation a me ka resilience o ka lāʻau ma lalo o ka paʻakikī kiʻekiʻe. ʻO ka pae paʻakikī o ka polyurethane elastomer ʻo Shore A10-D80.
2.High ikaika. ʻoi aku ka kiʻekiʻe o ko lākou ikaika haʻihaʻi a me ka hiki ke amo ma mua o ko ka ʻupena āpau ma lalo o ka paʻakikī like. I ka paʻakikī kiʻekiʻe, ʻoi aku ka kiʻekiʻe o kona ikaika hopena a me ka ikaika kulou ma mua o ka plastic.
3. He kūlana koʻikoʻi ka pale ʻana, ma ke ʻano he 0.01-0.10 (cm3) /1.61km, ma kahi o 3-5 mau manawa o ka lāʻau.
4.Excellent kaʻaila kū'ē. ʻO ka polyurethane elastomer kahi ʻano o ka pūhui polar polymer ikaika, he liʻiliʻi ka pilina me ka ʻaila mineral non-polar, a ʻaneʻane ʻaʻole ʻino ʻia i ka ʻaila a me ka ʻaila mechanical.
5. ʻO ka oxidation maikaʻi a me ke kūpaʻa ozone.
6. ʻOi aku ka maikaʻi o ka vibration absorption, me ka hoʻemi haʻalulu, ka hopena buffer.
7. Maikaʻi haʻahaʻa wela hana.
