Hardness Standard rau TPU-thermoplastic polyurethane elastomers

Lub hardness ntawmTPU (thermoplastic polyurethane elastomer)yog ib qho ntawm nws cov khoom tseem ceeb ntawm lub cev, uas txiav txim siab cov khoom muaj peev xwm tiv thaiv deformation, khawb, thiab khawb. Hardness feem ntau yog ntsuas siv Shore hardness tester, uas muab faib ua ob hom: Shore A thiab Shore D, siv los ntsuasTPU cov ntaub ntawvnrog txawv hardness ranges.

Raws li cov txiaj ntsig tshawb fawb, qhov nyuaj ntawm TPU tuaj yeem nyob ntawm ntug dej hiav txwv 60A mus rau Shore 80D, uas tso cai rau TPU kom nthuav dav qhov nyuaj ntawm cov roj hmab thiab cov yas thiab tuav cov elasticity siab thoob plaws tag nrho cov hardness ntau yam. Kev hloov kho ntawm hardness tuaj yeem ua tiav los ntawm kev hloov pauv ntawm cov khoom muag thiab cov ntu tawv hauv TPU molecular saw. Qhov kev hloov ntawm hardness tuaj yeem cuam tshuam rau lwm yam khoom ntawm TPU, xws li nce hardness ntawm TPU ua rau muaj kev nce hauv tensile modulus thiab lub zog tsim kua muag, nce rigidity thiab compressive kev ntxhov siab, txo qis hauv elongation, nce ceev thiab dynamic tshav kub tiam. , thiab nce nyob rau hauv ib puag ncig tiv thaiv.

Hauv kev siv tswv yim, covHardness xaiv ntawm TPUyuav raug txiav txim raws li kev thov tshwj xeeb. Piv txwv li, softer TPU ( ntsuas los ntawm Shore A hardness tester) yog tsim rau cov khoom uas yuav tsum tau ib tug mos kov thiab siab elongation, thaum nyuaj TPU (ntsuas los ntawm Shore D hardness tester) yog haum rau cov khoom uas yuav tsum tau muaj siab load-bearing muaj peev xwm thiab zoo. hnav tsis kam.

Tsis tas li ntawd, cov chaw tsim khoom sib txawv yuav muaj cov qauv hardness tshwj xeeb thiab cov khoom tshwj xeeb, uas feem ntau yog cov ncauj lus kom ntxaws hauv cov khoom siv kev qhia. Yog xav paub ntxiv, thov mus saib lub vev xaib official ntawmYantai Linghua Tshiab Khoom Co., Ltd.

Thaum xaiv TPU cov ntaub ntawv, ntxiv rau qhov hardness, lwm yam khoom siv lub cev, kev ua haujlwm, kev hloov pauv ib puag ncig, thiab tus nqi yuav tsum tau txiav txim siab los xyuas kom meej tias cov ntaub ntawv xaiv tuaj yeem ua tau raws li cov kev xav tau ntawm cov ntawv thov tshwj xeeb.
