Ntawm ZHONGHUI Group (ZHHIMG®), peb lub luag haujlwm ua tus thawj coj thoob ntiaj teb hauv cov khoom siv ultra-precision granite yuav tsum muaj kev nkag siab zoo txog cov khoom siv science. Peb tus tswv ZHHIMG® Dub Granite boasts qhov tshwj xeeb ntom ntom ntawm ≈ 3100 kg / m³, muab qhov tsis sib xws rigidity, thermal stability, thiab cov khoom tsis sib nqus - cov khoom tseem ceeb rau lub hauv paus ntawm niaj hnub semiconductor thiab cov khoom siv ntsuas. Txawm li cas los xij, txawm tias qhov zoo tshaj plaws granite tivthaiv yuav tsum muaj kev soj ntsuam nruj kom paub meej tias nws qhov zoo thiab kev nkag siab tob ntawm cov rog uas cuam tshuam nws qhov kev ruaj ntseg. Cov txheej txheem yooj yim, siv tau zoo li cas los txheeb xyuas qhov tseeb ntawm cov khoom siv, thiab cov txheej txheem dab tsi ua rau cov qauv ruaj khov no thaum kawg deform?
Authenticating lub plawv ntawm Precision: Granite khoom ntsuam xyuas
Cov kws tshaj lij engineers vam khom qhov tseem ceeb, tsis muaj kev puas tsuaj los ntsuas cov khoom siv ntawm cov khoom siv granite. Ib qho kev xeem zoo li no yog Kev Ntsuam Xyuas Liquid Absorption. Los ntawm kev siv me me ntawm tus cwj mem los yog dej rau saum npoo, cov khoom siv lub porosity tau tshwm sim tam sim ntawd. Kev tawg sai sai thiab kev nqus ntawm cov kua qhia tau hais tias xoob, ntxhib-grained qauv thiab siab porosity - cov yam ntxwv ntawm cov pob zeb tsis zoo. Hloov siab, yog tias cov hlaws ua kua thiab tawm tsam kev nkag mus, nws xav paub txog kev ua kom muaj kev saib xyuas cov av tsis suav nrog cov av noo noo kev hloov pauv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ntau qhov chaw ua haujlwm siab raug kho nrog cov khoom siv tiv thaiv; Yog li, kev tiv thaiv rau kev nkag mus yuav yog vim lub sealant qhov thaiv, tsis tsuas yog lub pob zeb qhov zoo.
Ib txoj hauv kev tseem ceeb thib ob yog Acoustic Integrity Test. Tapping qhov tivthaiv thiab ua tib zoo ntsuas lub suab tsim muaj kev pom rau hauv cov qauv sab hauv. Lub suab meej, nkig, thiab lub suab nrov yog lub cim ntawm homogeneous, cov qauv zoo tshaj plaws tsis muaj kev sib tsoo los yog voids. Lub suab dull lossis muffled, txawm li cas los xij, qhia tias muaj cov micro-cracks hauv lub cev lossis ib qho kev sib xyaw ua ke. Thaum qhov kev ntsuam xyuas no qhia txog lub pob zeb qhov sib xws thiab qhov sib txawv ntawm qhov sib txawv, nws yog ib qho tseem ceeb kom tsis txhob sib npaug ntawm lub suab nrov nkaus xwb nrog qhov tseeb ntawm qhov tseeb, vim tias cov zis acoustic kuj txuas nrog cov khoom sib txawv ntawm qhov loj thiab cov duab geometry.
Cov Mechanics ntawm Deformation: Vim li cas "Nruam" Cov Qauv Hloov
ZHHIMG® Cheebtsam yog cov sib dhos nyuaj, feem ntau muaj qhov sib txawv ntawm qhov sib txawv rau cov hlau ntxig thiab cov grooving meej, yuav tsum tau ua kom tau raws li cov kev xav tau ntau tshaj qhov yooj yim ntawm daim hlau. Txawm tias muaj kev ruaj khov heev, txawm tias cov ntaub ntawv no raug rau cov kev cai ntawm kev siv tshuab uas txiav txim siab deformation dhau lub neej. Nkag siab txog plaub hom kev hloov pauv ntawm cov qauv yog qhov tseem ceeb rau kev tiv thaiv kev tsim:
Deformation los ntawm Tension los yog Compression tshwm sim thaum sib npaug thiab opposite rog ua ncaj qha raws lub axis ntawm cov khoom, ua rau ib tug elongation los yog ib tug shortening ntawm granite tswv cuab. Thaum cov quab yuam raug siv los ntawm cov axis, lossis los ntawm kev tawm tsam lub sijhawm, cov khoom siv tau khoov, qhov chaw ncaj nraim hloov mus rau hauv txoj kab nkhaus - feem ntau hom tsis ua haujlwm nyob rau hauv qhov tsis sib xws. Ib qho kev sib hloov deformation hu ua Torsion tshwm sim thaum ob khub niam txiv sib npaug thiab sib npaug sib npaug ua rau qhov sib npaug ntawm cov axis, ua rau cov seem sab hauv sib tw rau ib leeg. Thaum kawg, Shear deformation yog tus cwj pwm los ntawm qhov sib npaug sib npaug zawv zawg ntawm ob feem ntawm cov khoom raws li cov kev taw qhia ntawm lub zog siv, feem ntau tshwm sim los ntawm sab nraud quab yuam. Cov rog no thaum kawg txiav txim siab txog lub voj voog ntawm lub neej thiab yuav tsum tau kuaj xyuas lub sijhawm.
Tswj Kev Ncaj Ncees: Cov Txheej Txheem rau Kev Ua Haujlwm Zoo
Txhawm rau kom ntseeg tau tias ZHHIMG® tus qauv ntawm qhov tseeb raug khaws cia, cov kws tshaj lij yuav tsum ua raws li cov txheej txheem ua haujlwm nruj. Thaum siv cov cuab yeej ntsuas ntsuas xws li granite ncaj npoo los yog sib npaug, cov cuab yeej ntsuas ntsuas yuav tsum tau lees paub ua ntej. Ob qhov ntsuas qhov saum npoo thiab cov khoom siv lub ntsej muag ua haujlwm yuav tsum tau ua kom huv si kom tsis txhob muaj cov khib nyiab los ntawm kev cuam tshuam rau lub dav hlau sib cuag. Qhov tseem ceeb, qhov ncaj ntug yuav tsum tsis txhob rub hla saum npoo thaum ntsuas; Hloov chaw, nws yuav tsum tau ntsuas ntawm ib qho taw tes, nqa tag nrho, thiab tom qab ntawd rov ua dua rau kev nyeem ntawv tom ntej. Qhov kev xyaum no tiv thaiv microscopic hnav thiab muaj peev xwm puas tsuaj rau nanometer-theem flatness. Tsis tas li ntawd, txhawm rau tiv thaiv kev ua haujlwm ntxov ntxov, cov khoom siv lub peev xwm yuav tsum tsis txhob dhau, thiab qhov chaw yuav tsum tau tiv thaiv los ntawm kev cuam tshuam tam sim ntawd. Los ntawm kev txhawb nqa cov txheej txheem kev qhuab qhia no, qhov muaj txiaj ntsig, kev ruaj ntseg ntev ntawm ZHHIMG® granite lub hauv paus tuaj yeem ua tiav, ua kom ntseeg tau qhov kev txiav txim siab tsis tu ncua uas xav tau los ntawm ultra-thov aerospace thiab microelectronics industries.
