Qhov nyuaj ntawmTPU (thermoplastic polyurethane elastomer)yog ib qho ntawm nws cov khoom tseem ceeb ntawm lub cev, uas txiav txim siab qhov muaj peev xwm ntawm cov khoom siv los tiv thaiv kev hloov pauv, khawb, thiab khawb. Qhov nyuaj feem ntau ntsuas siv Shore hardness tester, uas muab faib ua ob hom sib txawv: Shore A thiab Shore D, siv los ntsuasCov ntaub ntawv TPUnrog rau ntau yam hardness sib txawv.
Raws li cov txiaj ntsig tshawb nrhiav, qhov nyuaj ntawm TPU tuaj yeem yog txij li Shore 60A mus rau Shore 80D, uas tso cai rau TPU kom hla dhau qhov nyuaj ntawm roj hmab thiab yas thiab tswj tau qhov elasticity siab thoob plaws tag nrho qhov nyuaj. Kev hloov kho qhov nyuaj tuaj yeem ua tiav los ntawm kev hloov pauv qhov sib piv ntawm cov ntu mos thiab tawv hauv TPU molecular saw. Qhov kev hloov pauv ntawm qhov nyuaj tuaj yeem cuam tshuam rau lwm yam khoom ntawm TPU, xws li kev nce qhov nyuaj ntawm TPU ua rau muaj kev nce hauv tensile modulus thiab lub zog tsim kua muag, kev nce hauv kev nruj thiab kev ntxhov siab compressive, kev txo qis hauv elongation, kev nce hauv qhov ceev thiab dynamic cua sov, thiab kev nce hauv kev tiv thaiv ib puag ncig.
Hauv cov ntawv thov siv tau, covkev xaiv qhov nyuaj ntawm TPUyuav raug txiav txim siab raws li cov kev cai thov tshwj xeeb. Piv txwv li, TPU mos dua (ntsuas los ntawm Shore A hardness tester) yog qhov tsim nyog rau cov khoom uas xav tau kev kov mos mos thiab kev ntev ntev, thaum TPU tawv dua (ntsuas los ntawm Shore D hardness tester) yog qhov tsim nyog rau cov khoom uas xav tau lub peev xwm thauj khoom siab thiab kev tiv thaiv kev hnav zoo.
Tsis tas li ntawd xwb, cov chaw tsim khoom sib txawv yuav muaj cov qauv tawv thiab cov lus qhia tshwj xeeb ntawm cov khoom, uas feem ntau yog cov lus qhia ntxaws ntxaws hauv cov phau ntawv qhia txog cov khoom.

Thaum xaiv cov ntaub ntawv TPU, ntxiv rau qhov nyuaj, lwm yam khoom siv lub cev, cov txheej txheem ua tiav, kev hloov pauv ib puag ncig, thiab cov nqi yuav tsum tau txiav txim siab kom ntseeg tau tias cov ntaub ntawv xaiv tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov ntawv thov tshwj xeeb.
