Qhov zoo
Ntuj Elasticity: Roj hmab rollers muaj npe nrov rau lawv cov khoom muaj zog elastic. Qhov elasticity no ua rau lawv pliable thiab yoog raws, haum rau ntau daim ntawv thov thoob plaws ntau yam lag luam.
Kev sim thiab sim: Roj Hmab tau ua ib qho tseem ceeb hauv kev lag luam rau cov menyuam rau ntau xyoo. Nws cov keeb kwm ntev ntev ntawm kev siv ua pov thawj rau nws txoj kev ntseeg tau thiab kev ntseeg siab kev lag luam tau muab tso rau hauv nws ntau xyoo lawm.
Tus nqi qis dua: Kev hais lus nyiaj txiag, cov menyuam roj hmab feem ntau nthuav tawm qhov kev xaiv pheej yig dua pib. Lawv cov nqi pem hauv ntej feem ntau qis dua piv rau lawv cov polyurethane counterparts, ua rau lawv muaj kev xaiv zoo rau cov neeg siv nyiaj nruj dua.
Customization: Ib qho tseem ceeb ntawm lub zog ntawm cov roj hmab rollers yog qhov muaj peev xwm ntawm infusing lawv nrog cov muab tub lim tshwj xeeb. Qhov sib ntxiv no tso cai rau cov tuam txhab tsim kho thiab hloov cov khoom ntawm cov roj hmab kom zoo dua rau kev ua haujlwm tshwj xeeb.
Qhov tsis zoo
Durometer Limitation: Thaum cov menyuam roj hmab muaj ntau yam, lawv muaj lawv cov ciam teb ntawm hardness. Lawv qhov ntsuas durometer feem ntau yog nyob nruab nrab ntawm 30 Shore A txog 90 Shore A, uas yuav tsis haum rau txhua qhov kev lag luam.
Teeb meem Marring: Ib qho teeb meem tseem ceeb ntawm cov roj hmab chais yog lawv nyiam tawm cov cim. Cov khoom, tshwj xeeb tshaj yog cov uas muag muag los yog rhiab qhov xwm txheej, muaj feem xyuam rau scuffing los yog cim thaum ua tiav nrog roj hmab rollers.
Wet Environment Vulnerability: Roj Hmab, tshwj xeeb tshaj yog thaum raug cov dej ntub dej rau lub sijhawm ntev, muaj kev cuam tshuam rau rotting lossis degrading. Qhov no ua rau lawv tsis zoo rau kev ua haujlwm uas tsis tu ncua los yog ntub dej.
Chemical Sensitivities: Roj Hmab tsis tiv thaiv cov teebmeem ntawm qee yam tshuaj. Kev cuam tshuam rau qee qhov tuaj yeem hloov kho nws cov khoom, muaj peev xwm txo qis nws cov txiaj ntsig thiab kev ua neej.
Abrasion Resistance: Thaum pitted tiv thaiv polyurethane, roj hmab poob luv luv nyob rau hauv cov nqe lus ntawm abrasion kuj. Qhov no ua rau lawv tsis haum rau qhov chaw muaj kev sib txhuam siab uas hnav thiab tsim kua muag.
