Indicators rau characterizing lub cev thiab mechanical zog ntawm roj hmab:
1. Tensile lub zog: tseem hu ua tensile lub zog los yog tensile lub zog, hais txog lub load uas ib tug qauv tuaj yeem tiv taus ib chav tsev thaum ncab mus rau tawg, ntsuas hauv megapascals (MPa), yav dhau los ntsuas hauv kilograms ntawm quab yuam ib square centimeter (kgf / cm2).
2. Tensile stress: yav tas los hu ua tensile lub zog, nws hais txog lub load rau ib chav tsev cheeb tsam uas ib tug qauv tuaj yeem tiv taus thaum ncab mus rau ib qho ntev. Chav ntsuas ntsuas yog tib yam li lub zog tensile. Feem ntau siv yog 100%, 300%, thiab 500% tensile stress. Nws qhia txog lub peev xwm ntawm roj hmab los tiv thaiv sab nraud deformation.
3. Tear lub zog: Lub load rau ib chav tsev thickness uas ib tug tshwj xeeb specimen (nrog ib tug txiav los yog txoj cai angled duab) tuaj yeem tiv taus thaum torn, qhia txog cov khoom tsim kua muag, ntsuas hauv kN / m.
4. Elongation: Thaum cov khoom kuaj tau rub tawm, qhov sib piv ntawm qhov elongation ib feem ntawm qhov ntev yog hu ua elongation; Qhia raws li feem pua.
5. Permanent deformation: Qhov feem pua ntawm qhov tsis tuaj yeem rov qab los ntawm qhov ntsuas qhov ntev elongation deformation tom qab cov qauv raug ncab mus rau pob txha. Tom qab tso tawm cov quab yuam sab nraud thiab tawm mus rau qee lub sijhawm (feem ntau 3 feeb), qhia raws li feem pua.
6. Resilience: tseem hu ua cuam tshuam elasticity, hais txog lub peev xwm ntawm cov roj hmab kom rov qab tau nws lub xeev qub tom qab raug cuam tshuam, qhia hauv%.
7. Hardness: Hais txog lub peev xwm ntawm roj hmab los tiv thaiv sab nraud, feem ntau ntsuas los ntawm Shore hardness tester. Lub hardness ntau ntawm cov roj hmab feem ntau yog nyob nruab nrab ntawm 20 thiab 100, ntsuas hauv Shore A.
