HRB-150TS Yas Pob Indentation Hardness Tester (4)

Lub pob indentation hardness tester tuaj yeem siv los ntsuas qhov hardness ntawm cov ntaub ntawv hauv tsheb engineering plastics, tawv roj hmab, cov khoom siv hauv tsev thiab lwm yam lag luam, thiab tuaj yeem ua cov ntaub ntawv thiab luam tawm.

Product Description:

Yas hardness yog hais txog lub peev xwm ntawm cov khoom yas los tiv thaiv kev nias rau hauv nws los ntawm lwm yam khoom nruj uas pom tau tias tsis ua rau elastic thiab yas deformation.

Kev ntsuam xyuas qhov tawv tawv ntawm lub pob yas yog siv lub pob steel nrog ib txoj kab uas hla mus rau vertically nias rau hauv qhov chaw ntawm cov qauv hauv qab qhov kev txiav txim ntawm qhov kev xeem load, thiab nyeem qhov tob indentation tom qab tuav rau ib lub sijhawm.Tus nqi hardness yog tau los ntawm kev xam los yog saib lub rooj.

1, lub thickness ntawm cov qauv yog tsis tsawg tshaj li 4 hli, lub loading ceev yuav hloov nyob rau hauv 2-7 vib nas this, feem ntau 4-6 vib nas this, thiab lub sij hawm thauj khoom yog 30 vib nas this los yog 60 vib nas this;Lub load loj yuav tsum tau xaiv raws li qhov yuav tsum tau hardness ntawm cov qauv, thiab lub hardness siab dua yuav xaiv ib tug loj load;Txwv tsis pub, cov khoom me me yog siv.Yog tias qhov hardness ntawm cov qauv tsis tuaj yeem kwv yees tau, nws yuav tsum tau maj mam hloov kho los ntawm kev thauj khoom me me, thiaj li tsis ua kom puas lub pob indenter thiab cov qauv;Feem ntau, qhov kev ntsuam xyuas tuaj yeem ua tiav ntev npaum li qhov kev thauj khoom raug xaiv raws li qhov xav tau ntawm cov qauv.

2, pob indentation hardness yog hais txog cov kab uas hla ntawm lub pob steel, nyob rau hauv qhov kev txiav txim ntawm qhov kev xeem load vertically nias rau saum npoo ntawm cov qauv, tuav ib lub sij hawm, qhov nruab nrab siab ntawm ib cheeb tsam mus rau Kgf / mm2 los yog N / mm2. qhia
