Kev Ntsuas Kev Tiv Thaiv Kev Nyuaj Siab: Feem ntau siv txoj kev sib tsoo log abrasion los yog lub nruas abrasion txoj kev los ntsuas qhov hnav tsis kam los ntawm kev ntsuas cov khoom poob ntawm ib chav tsev ntawm lub sijhawm lossis nyob deb.
Kev Ntsuas Hardness: Siv lub Shore hardness tester los ntsuas cov khoom tsis kam rau indentation hauv compression; Shore A hardness feem ntau yog siv rau cov ntaub ntawv elastic polyurethane, thaum Shore D hardness yog siv rau cov ntaub ntawv nruj.
Tensile Strength and Elongation at Break: Ntsuam xyuas cov khoom siv tensile muaj peev xwm thiab ductility - ntsuam xyuas nws cov kev ua tau zoo nyob rau hauv tensile stress -los ntawm kev siv lub tshuab kuaj universal.
Resilience Testing: Ntsuas cov polyurethane lub peev xwm los elastically rov qab los ntawm cov kev ntsuam xyuas elastic rebound.
Impact Resistance Testing: Yuav tsum siv lub zog cuam tshuam rau cov khoom siv uas siv lub tshuab ntsuas qhov cuam tshuam los saib seb cov khoom puas tawg lossis tawg.
Corrosion Resistance Testing: Koom nrog rau kev nthuav tawm cov khoom rau acidic, alkaline, lossis roj-raws li ib puag ncig rau lub sijhawm tshwj xeeb los ntsuas nws cov tshuaj tiv thaiv corrosion.
