Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Pob Zeb Diamond Sintering Moulds, Kuv feem ntau tau nug txog txhua yam kev paub meej. Ib lo lus nug uas tshwm sim me ntsis yog, "Dab tsi yog Young's modulus ntawm pob zeb diamond sintering pwm? Cia peb dhia dej mus rau hauv nws thiab rhuav tshem qhov no hauv txoj hauv kev uas yooj yim to taub.
Ua ntej tshaj, cia peb mus nrawm dua qhov Young's modulus tiag tiag. Young's modulus, tseem hu ua elastic modulus, yog ib qho kev ntsuas ntawm qhov tawv ntawm cov khoom. Hauv cov ntsiab lus yooj yim, nws qhia peb ntau npaum li cas cov khoom yuav deform nyob rau hauv ib qho kev ntxhov siab. Yog tias cov khoom muaj lub siab Young's modulus, nws txhais tau tias nws zoo nkauj tawv thiab yuav tsis deform yooj yim. Ntawm qhov tod tes, ib qho qis Young's modulus qhia tias cov khoom siv tau yooj yim dua thiab yuav deform yooj yim dua.
Tam sim no, thaum nws los txog rau pob zeb diamond sintering pwm, lawv tau ua kom tawv thiab ruaj khov. Pob zeb diamond yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws nyob rau hauv, thiab thaum siv sintering pwm, nws muab qee yam khoom zoo heev. Cov Young's modulus ntawm pob zeb diamond sintering pwm yog siab heev. Feem ntau, cov Young's modulus ntawm pob zeb diamond tuaj yeem muaj li ntawm 1,000 txog 1,200 gigapascals (GPa). Qhov ntawd yog super siab piv rau ntau yam khoom siv.
Txhawm rau muab qhov no rau hauv qhov kev xav, cia peb xav txog qee yam khoom siv. Hlau, uas paub tias muaj zog, muaj ib tug Young's modulus ntawm ib ncig ntawm 200 GPa. Yog li, lub pob zeb diamond sintering pwm yog txoj kev nruj dua hlau. Qhov siab nruj no yog qhov tseem ceeb heev vim tias thaum lub sij hawm sintering, cov pwm yuav tsum tiv taus ntau lub siab thiab kub. Yog tias cov pwm tsis nruj txaus, nws tuaj yeem deform, uas yuav cuam tshuam cov duab thiab zoo ntawm cov khoom sintered.
Lwm qhov laj thawj yog vim li cas qhov siab Young's modulus ntawm pob zeb diamond sintering pwm yog qhov tseem ceeb rau qhov tseeb. Thaum koj tab tom ua cov khoom los ntawm sintering, koj xav tau cov pwm kom nws cov duab raws nraim li tsim. Nrog lub siab Young's modulus, cov pwm tuaj yeem tswj nws qhov ntev kom raug, kom ntseeg tau tias cov khoom kawg ua tau raws li qhov yuav tsum tau ua.
Tam sim no, kuv paub qee tus ntawm koj yuav xav paub seb peb ntsuas qhov Young's modulus ntawm pob zeb diamond sintering pwm li cas. Zoo, muaj ob peb txoj kev sib txawv. Ib txoj hauv kev yog los ntawm cov txheej txheem hu ua nanoindentation. Hauv nanoindentation, ib qho me me indenter yog nias rau hauv qhov chaw ntawm cov khoom, thiab ntsuas lub zog thiab qhov tob ntawm qhov indentation. Los ntawm kev txheeb xyuas cov kev ntsuas no, peb tuaj yeem suav cov Young's modulus.
Tab sis nws tsis yog hais txog pob zeb diamond xwb. Txoj kev siv pob zeb diamond siv rau hauv sintering pwm kuj cuam tshuam rau nws cov khoom. Piv txwv li, qhov zoo ntawm cov pob zeb diamond hais, lawv nyob li cas nyob rau hauv pwm, thiab cov ntaub ntawv binder siv los tuav lawv ua ke txhua tus ua lub luag haujlwm. Ib qho zoo - ua pob zeb diamond sintering pwm nrog siab - pob zeb diamond zoo thiab cov ntaub ntawv zoo yuav muaj qhov zoo sib xws thiab txhim khu kev qha Young's modulus.
Raws li ib tus neeg muag khoom ntawm Pob Zeb Diamond Sintering Moulds, peb ua tib zoo saib xyuas kom ntseeg tau tias peb cov pwm muaj cov khoom zoo. Peb siv qib siab - cov pob zeb diamond thiab cov txheej txheem tsim khoom siab heev kom paub tseeb tias Young's modulus yog qhov yuav tsum tau ua. Txoj kev no, peb cov neeg siv khoom tuaj yeem ntseeg tau tias peb cov pwm yuav ua tau zoo nyob rau hauv cov xwm txheej nyuaj ntawm cov txheej txheem sintering.
Tam sim no, dhau li pob zeb diamond sintering pwm, peb kuj muab lwm yam khoom muaj feem xyuam. Piv txwv li, peb muaj Graphite Gaskets Rau Machinery Thiab Khoom. Cov gaskets no zoo heev rau kev sib khi daim ntaub ntawv hauv tshuab thiab khoom siv. Lawv muaj cov thermal thiab tshuaj tiv thaiv zoo, uas ua rau lawv haum rau ntau yam kev lag luam.
Peb kuj muaj Graphite Waterway rau Pob Zeb Diamond Core Khoom. Cov dej no yog tsim los txhim kho kev ua haujlwm ntawm cov pob zeb diamond cores. Lawv pab nrog cov cua sov dissipation thiab tuaj yeem txuas lub neej ntawm cov khoom tseem ceeb.
Thiab yog tias koj nyob hauv kev ua lag luam rau cov cuab yeej txiav, peb muab Graphite Saw Hniav. Cov saw hniav no yog tsim los nrog siab - zoo graphite thiab tsim los muab kev txiav kom huv si thiab ua haujlwm zoo.
Yog tias koj txaus siab rau ib qho ntawm peb cov khoom, txawm tias nws yog pob zeb diamond sintering pwm lossis peb lwm cov graphite - raws li cov khoom lag luam, tsis txhob yig tiv tauj. Peb ib txwm zoo siab los tham txog koj cov kev xav tau thiab saib seb peb tuaj yeem pab tau li cas. Txawm hais tias koj yog ib lub chaw tsim khoom me me - lossis lub tuam txhab kev lag luam loj, peb muaj cov khoom lag luam thiab kev txawj ntse los txhawb koj txoj haujlwm.
Hauv kev xaus, Young's modulus ntawm pob zeb diamond sintering pwm yog cov cuab yeej tseem ceeb uas ua rau cov pwm no muaj txiaj ntsig. Lawv lub siab tawv ua rau lawv tuaj yeem tiv taus qhov nruj ntawm cov txheej txheem sintering thiab xyuas kom siab - cov khoom zoo, meej. Yog tias koj tab tom nrhiav kev txhim khu kev qha sintering pwm lossis lwm yam khoom lag luam, thov hu rau peb, thiab cia peb pib sib tham txog koj cov kev xav tau.
