Lub neej kev pab cuam ntawm hnav-cov khoom tiv thaiv polyurethane yog cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv hauv nws tus kheej, kev ua haujlwm ntawm cov khoom siv, thiab cov yam ntxwv ntawm cov khoom siv. Cov ntaub ntawv hardness, elasticity, ntom, thiab puas kuj ncaj qha txiav txim siab ntev npaum li cas cov khoom yuav nyob rau hauv siab - cuam tshuam thiab siab - kev sib txhuam ib puag ncig; hardness tsis txaus tuaj yeem ua rau hnav sai, thaum hnyav hnyav tuaj yeem ua rau muaj kev pheej hmoo ntawm pob txha tawg. Cov cuab yeej ua haujlwm tau zoo-xws li kev vibration zaus, cov khoom siv quab yuam, thiab kev thauj mus los nrawm- kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lub neej ntev. Tsis tas li ntawd, cov khoom ntawm cov khoom xa tuaj (xws li, qhov loj me, hardness, corrosiveness, thiab noo noo cov ntsiab lus) thiab ib puag ncig kev khiav hauj lwm ib puag ncig (xws li, kub kub, raug rau acids los yog alkalis, thiab abrasive tej yam kev mob) yog tag nrho cov tseem ceeb yam tseem ceeb. Nyob ntawm cov kev ua haujlwm tshwj xeeb, kev pabcuam lub neej ntawm kev hnav- cov khoom tiv thaiv polyurethane tuaj yeem nyob qhov twg los ntawm ob peb lub hlis mus rau ntau xyoo.
Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm hnav- cov khoom tiv thaiv polyurethane, ib txoj hauv kev uas suav nrog kev xaiv cov khoom siv, kev teeb tsa, thiab kev tswj xyuas kev ua haujlwm yog qhov tseem ceeb. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv polyurethane uas tsim nyog hardness thiab elasticity, thiab tsim cov khoom 'thickness thiab geometry judiciously raws li cov khoom siv tshwj xeeb. Thaum lub sij hawm installation, xyuas kom meej tias lub Cheebtsam yog zaum tusyees thiab ruaj ntseg fastened los tiv thaiv lub zos kev nyuaj siab concentrations los yog misalignment. Tsis tas li ntawd, thaum lub sijhawm ua haujlwm, ua cov tshuaj ntsuam xyuas ib ntus txhawm rau saib xyuas cov qib hnav, thiab kho cov cuab yeej ua haujlwm tam sim kom tsis txhob overloading lossis ntau dhau kev co. Los ntawm kev siv cov kev ntsuas no, cov khoom siv tu cov nqi tuaj yeem txo qis thaum tib lub sijhawm tiv thaiv kev ua haujlwm ntau lawm.
