Wanne kayan aiki ne mafi kyau, nailan ko polyurethane casters?

Sau da yawa muna ganin kayan guda biyu, nailan da polyurethane, a cikin kayayyaki daban-daban, musamman a fannin kayan gyaran mota. Amma menene ainihin bambanci tsakaninsu, wanne ne ya fi aiki? Bari mu bincika tare.
Da farko dai, muna buƙatar fahimtar babban bambanci tsakanin waɗannan kayan guda biyu. A taƙaice dai, polyurethane abu ne mai laushi wanda yake da laushi, don haka ba ya da hayaniya kuma yana da ƙarin gogayya. Wannan yana nufin cewa masu yin amfani da polyurethane sun fi shiru a aiki, amma ƙila ba sa jure lalacewa kamar masu yin amfani da nailan.

Kuma nailan abu ne mai tauri, wanda ke da kyakkyawan juriya ga gogewa. Don haka idan kuna buƙatar nailan mai ƙarfin kaya da juriya ga lalacewa, nailan na iya zama mafi dacewa a gare ku!

Ana yin polyurethane ta hanyar polymerization isocyanate tare da mahaɗan hydroxyl, kuma yana da kyakkyawan juriya ga mai, tauri, juriya ga gogewa, juriya ga tsufa da mannewa. A gefe guda kuma, nailan yana da juriya mai yawa ga zafi, juriya ga gajiya da juriya ga gogewa, da kuma kyakkyawan ƙarfin injina da kwanciyar hankali.
