Roj hmab thiab polyurethane yog ob yam khoom siv feem ntau siv hauv kev lag luam caster. Cov khoom sib txawv muaj cov khoom sib txawv. Ntau tus neeg yuav nug, qhov twg zoo dua, polyurethane log lossis roj hmab log? Hauv kev sib piv, polyurethane log muaj qhov zoo dua qhov zoo dua li cov roj hmab log.

Qhov zoo ntawm polyurethane log

1. Kev pab lub neej: Piv nrog roj hmab log, polyurethane log muaj kev hnav zoo dua thiab kev pab lub neej ntev, uas tuaj yeem txo tus nqi ntawm kev siv.

2. Load-bearing muaj peev xwm: Polyurethane log muaj kev tiv thaiv zoo dua rau kev loj hlob tawg thiab tsim kua muag. Lub peev xwm thauj khoom muaj peev xwm ntau dua li cov roj hmab log, ob peb zaug ntau dua li cov roj hmab log.

3. Rolling resistance: Cov qauv tshuaj ntawm cov khoom siv polyurethane txiav txim siab tias nws muaj qhov ua haujlwm me me dua li cov roj hmab, yog li qhov kev tiv thaiv ntxiv yog me dua thiab txuag zog ntau dua.

4. Hardness thiab resilience: Lub hardness ntawm roj hmab log yog qhov tsawg, thaum lub hardness ntawm polyurethane log yog ntau dua li cov roj hmab log. Kev siv lub log polyurethane tuaj yeem muaj peev xwm buffering, muaj zog load-bearing muaj peev xwm, thiab qis dov kuj. Lub log hardness thiab rov ua haujlwm ntawm cov ntaub ntawv polyurethane kuj tuaj yeem hloov kho raws li cov neeg siv khoom xav tau thiab kev siv ib puag ncig.
