Qhov twg yog cov hnav ntau dua - tiv taus, polyurethane lossis roj hmab casters?

Polyurethane Casters feem ntau ntau dua cov hnav - tsis kam tshaj li roj hmab.

Polyurethane yog elastomer ntawm cov roj hmab thiab yas, thiab nws cov qauv molecular tuaj yeem hloov kho los ntawm kev tsim qauv los hloov nws cov khoom.

Polyurethane casters feem ntau nyuaj dua li cov khoom siv roj hmab, muab cov kua ntau dua thiab ua tsis taus. Cov ntaub ntawv uas cuam tshuam qhia tias Polyurethane txoj kev coj tawm tsam yog 3 {{4 4}}}}} paab, thiab huab roj roj hmab nitrile. Hauv kev siv cov xwm txheej thauj khoom zoo, cov nqi ntawm cov log tsheb polyurethane tsuas yog 0.01-0.1 cm /,61 km.

Txawm li cas los xij, cov tshuab roj hmab muaj lawv tus kheej zoo, xws li elasticity zoo, anti {{{}} kev nqus. Nyob rau qee qhov chaw ib puag ncig, xws li tshwj xeeb tshaj yog ntxhib lossis ntub dej, cov tshuab roj hmab yuav muaj qhov zoo dua coj tsis kam, tab sis tag nrho, polyurethane casters muab cov kev coj zoo dua.
