Hloov ntawm Shore (SH) Hardness thiab Mohs (MH) Hardness

Shore hardness thiab Mohs hardness yog ob txoj hauv kev los ntsuas qhov hardness ntawm cov khoom. Kev sib raug zoo ntawm kev hloov dua siab tshiab ntawm lawv yog raws li hauv qab no:

I. Cov Ntsiab Cai

• Shore hardness (SH): Kuj hu ua gravitational hardness, nws yog ib qho Performance index rau ntsuas qhov hardness ntawm ib yam khoom raws li qhov deformation qhov tob uas tsim los ntawm cov khoom tiv thaiv lub ntiajteb txawj nqus.
• Mohs hardness (MH): Kuj tseem hu ua repulsive hardness, nws yog ib qho kev sim rau kev suav hardness los ntawm kev siv lub indenter rau saum npoo ntawm ib yam khoom thiab raws li qhov siab bounced rov qab los ntawm qhov chaw ntawm cov khoom.

II. Txoj kev hloov dua siab tshiab

Raws li cov saum toj no ob txoj kev sim hardness, peb tuaj yeem siv cov qauv hauv qab no los hloov kev sib raug zoo ntawm Shore hardness thiab Mohs hardness:

Hiav txwv hardness (SH) = 2.871 (MH)² - 2.406 × (MH) + 0.226

Ntawd yog, tom qab tau txais Mohs hardness ntawm ib yam khoom, Lub Nkoj hardness tuaj yeem xam los ntawm cov qauv saum toj no.

III. Cov ntawv thov tshwj xeeb

Hauv kev siv tswv yim, peb feem ntau siv Mohs hardness los ntsuas qhov hardness ntawm cov khoom, tab sis nyob rau hauv tej lub sij hawm los yog rau tej lub hom phiaj, Shore hardness kuj siv tau rau kev ntsuas. Piv txwv li, Shore hardness feem ntau yog siv los kwv yees lub plasticity thiab elasticity ntawm cov ntaub ntawv hlau thiab hnav kev ua tau zoo ntawm cov cuab yeej npoo. Tsis tas li ntawd, vim Shore hardness tuaj yeem sawv cev tus nqi ntawm cov ntaub ntawv, Shore hardness feem ntau yuav tsum tau txheeb xyuas thiab ntsuas lub cev lub cev ntawm cov ntaub ntawv thaum tsim thiab tsim cov khoom nyuaj.

IV. Thaum kawg

Ob leeg Shore hardness thiab Mohs hardness yog inductive xeem txoj kev siv los xyuas kom meej hardness thiab lub cev ntawm cov khoom. Kev sib raug zoo ntawm kev hloov dua siab tshiab ntawm lawv tuaj yeem tau txais los ntawm cov qauv saum toj no. Kev ntsuas cov txiaj ntsig ntawm ob txoj hauv kev no tuaj yeem pom tseeb cov khoom ntawm lub cev ntawm cov khoom, yog li lawv feem ntau siv los txheeb xyuas thiab ntsuas cov khoom siv raw thaum tsim thiab tsim cov khoom siv.
