Uas lub log tsheb loj trolley lub log yog qhov zoo dua haum rau cov chaw noo noo: polyurethane lossis nylon?

Nyob rau hauv ib puag ncig huab cua, Polyurethane Casters feem ntau ntau dua cov nylon casters. Cov laj thawj yog li nram qab no:

Dej Tsis kam: Nylon hygroscopic thiab nqus dej noo, muaj peev xwm ua rau muaj kev cuam tshuam nrog kev ua tau zoo thiab kev teeb tsa. Thaum zoo polyurethane muaj cov cawv tsis zoo, ua rau nws tsis zoo rau hauv dej, hloov kho cov polyurethanes, ua rau muaj kev tiv thaiv cov dej sib txawv, ua kom muaj kev tiv thaiv kev nkag rau hauv kev nkag mus thiab xeb.

Kev sib txhuam coefficient: Nylon casters yog nquag mus rau gripping hauv cov puag ncig huab cua, tshwj xeeb tshaj yog thaum nce toj siab lossis ntawm cov chaw nce toj. Polyurethane casters, ntawm qhov tod tes, muaj kev sib txhuam siab dua thiab muaj kev sib txhuam zoo dua qub xws li dej ntub xws li dej ntub xws li dej, tiv thaiv plam.

Corrosion Kuj: Thaum Nylon caslon casters yog me ntsis kev tiv taus rau ntau cov tshuaj lom neeg, lawv txoj kev ua tau zoo tuaj yeem cuam tshuam los ntawm kev ntub dej. Polyurethane casters, tshwj xeeb tshaj yog cov dej hloov, tsis yog tsuas yog dej- tiv taus rau ntau yam tshuaj lom xws li roj thiab kua qaub.
