Qhov ruaj khov: Cov Hlau Pob Indenter muaj siab ntev thiab yog qhov haum rau kev siv ntev thiab rov siv dua. Ntau yam ntawm cov ntawv thov: Muaj peev xwm sim ntau yam ntawm cov ntaub ntawv hlau nyuaj.
Cov kev txwv lossis cov kev txwv: qauv loj: yuav tsum muaj cov qauv loj yog qhov tsim nyog kom paub tseeb tias qhov kev ua kom loj txaus thiab muaj tseeb, thiab cov qauv ntawm cov qauv yuav tsum yog tiaj thiab huv. Tej yam yuav tsum muaj: Qhov chaw nyob yuav tsum tau du thiab tsis muaj qhov tsis zoo los xyuas kom meej qhov tseeb. Cov cuab yeej saib xyuas: Cov khoom siv yuav tsum tau ntsuas thiab tswj kom muaj qhov tseeb thiab rov ntsuas dua.
(2) HB5 / 750
Txoj kev ua haujlwm thiab lub hauv paus ntsiab lus: Siv cov pob txheem hlau nrog lub cheeb ntawm 550 kg, thiab ntsuas qhov indentation inch los laij tus nqi tawv.
Cov Khoom Siv Khoom Siv: Siv tau rau cov ntaub ntawv hlau nrog cov tawv tawv tawv, xws li tooj liab alloys, alloys aluminium, thiab nruab nrab tawv steel. ③ Cov ntaub ntawv tso cai ib yam: Tswjhwm Zoo ntawm nruab nrab hardness hlau cov ntaub ntawv. Cov khoom tshawb nrhiav thiab kev txhim kho thiab kev kuaj sim. Kev kuaj cov khoom siv tawv thaum tsim khoom thiab ua tiav. Cov yam ntxwv thiab cov txiaj ntsig: nruab nrab load: Siv rau cov ntaub ntawv nrog cov tawv tawv thiab muaj peev xwm raug ntsuas lawv lub hardness. Kev siv tau yooj ywm: muaj feem xyuam rau ntau yam nruab nrab cov ntaub ntawv nyuaj nrog cov khoom muaj zog. Kev ua kom rov muaj tseeb: muab ruaj ruaj thiab kev ntsuas ntsuas tau.
Cov kev txwv lossis kev txwv: Qauv Npaj: Cov qauv saum toj uas yuav tsum tau tiaj thiab huv si kom ntseeg tau qhov tseeb ntawm qhov ntsuas tau. Cov khoom txwv: Rau cov ntaub ntawv muag muag heev lossis cov khoom siv nyuaj heev, lwm txoj kev ntsuas nyuaj rau kev sim ua yuav tau xaiv. Cov cuab yeej saib xyuas: cov khoom siv yuav tsum tau ntsuas thiab tswj kom ua kom paub tseeb qhov tseeb thiab kev ntseeg tau ntawm qhov ntsuas.
(3) HB2.5 / 187.5
Txoj kev ua haujlwm thiab lub hauv paus ntsiab lus: Siv cov pob txheem hlau nrog lub cheeb ntawm 2.5 mm mus nias rau hauv cov khoom ntawm 187,5 kg, thiab ntsuas qhov indentation inch los laij tus nqi tawv.
Cov Khoom Siv Khoom Siv Khoom Siv: Muaj feem xyuam rau softer cov ntaub ntawv hlau thiab qee cov mos muag alloys, xws li txhuas, txhuas alloy, thiab cov hlau mos.
③Common Daim Ntawv Thov Zaj Dab Tsi: Tswjhwm Zoo ntawm cov ntaub ntawv mos muag hlau. Cov khoom siv tshuaj ntsuam hauv cov khoom siv hluav taws xob thiab kev lag luam hluav taws xob. Hardness kuaj cov khoom mos mos thaum tsim khoom thiab ua tiav.
④Features thiab cov txiaj ntsig: qis thauj: muaj feem xyuam rau cov ntaub ntawv softer kom tsis txhob muaj kev cuam tshuam ntev. Kev ua kom rov muaj tseeb: muab ruaj ruaj thiab kev ntsuas ntsuas tau. Ntau yam ntawm cov ntawv thov: Muaj peev xwm sim ntau yam ntawm softer cov ntaub ntawv hlau.
⑤ Cov Lus Cim lossis Txwv: Qauv Npaj: Cov qauv saum toj no yuav tsum tau tiaj thiab huv si kom ntseeg tau qhov tseeb ntawm qhov ntsuas tau. Txwv cov khoom txwv: rau cov ntaub ntawv nyuaj, nws yuav tsim nyog los xaiv lwm txoj kev ntsuas tsim nyog. Kev Txij Nkawm: Cov Khoom Siv Yuav Tsum Tau Ua Kom Zoo thiab tswj kom muaj kev ntsuas qhov tseeb thiab kev ntseeg tau.
