Hvad er de strukturelle egenskaber ved polyurethanvalser?

Polyurethanruller og massive gummidæk er meget udbredt i rækkevidde gaffeltrucks, smalgangsgaffeltrucks, side-/multi{0}}retningsgaffeltrucks, elektriske stablere, palletrucks, pallestablere og trailere til havneterminaler bruges også til transmission, vejledning og støtte til industri- og minedrift, metallurgi og udstyrs samlebånd. Den høje styrke, høje belastningsbæring, høje modstandsdygtighed, høje slidstyrke, høje rivebestandighed og andre egenskaber ved polyurethanruller er uovertruffen af ​​almindelige naturgummidæk.

Polyurethanruller har følgende egenskaber:

Polyurethane rollers are manufactured by casting process, and their structure is very different from the tires currently produced. A full polyurethane pneumatic tire is composed of three parts: the carcass, the belt layer and the tread. Among them, the carcass is made of polyurethane elastomer with higher modulus, which is relatively hard, so it has better fatigue resistance, dimensional stability and cutting resistance; the belt layer on the upper part of the carcass is made of aramid fiber wound in the circumferential direction Or steel cords, and the tread is cast from a low-modulus polyurethane elastomer to ensure the tire's wear resistance and ride performance.
