Hauv kev tsim khoom precision, aerospace, thiab metrology industries, kev ua tau zoo ntawm cov khoom siv kho tshuab (piv txwv li, cov rooj ua haujlwm tshuab, cov hauv paus, thiab cov hlau qhia) cuam tshuam ncaj qha rau qhov tseeb ntawm cov khoom siv thiab kev ruaj khov ntawm kev ua haujlwm. Cov khoom granite thiab cov khoom marble ob leeg raug cais ua cov cuab yeej precision pob zeb ntuj, tab sis cov khoom granite sawv tawm rau lawv qhov nyuaj thiab ruaj khov - ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv high-load, high-frequency industrial applications. Ua tus thawj coj thoob ntiaj teb ntawm cov khoom siv precision pob zeb, ZHHIMG cog lus tias yuav ua kom meej txog cov khoom siv thiab cov txiaj ntsig tseem ceeb ntawm cov khoom granite, pab koj xaiv qhov kev daws teeb meem zoo tshaj plaws rau koj cov khoom siv precision.
1. Cov Khoom Siv ntawm Granite Cheebtsam yog dab tsi?
Cov khoom siv granite yog ua los ntawm cov granite ntuj zoo—ib hom pob zeb igneous uas tsim los ntawm kev txias qeeb thiab khov ntawm cov magma hauv av. Tsis zoo li marble ib txwm, kev xaiv cov khoom siv raw rau cov khoom siv granite ua raws li cov qauv kev lag luam nruj kom ntseeg tau tias muaj kev ua haujlwm zoo thiab kev khaws cia qhov tseeb:
1.1 Cov Khoom Siv Tseem Ceeb Yuav Tsum Tau Ua
- Qhov Nyuaj: Yuav tsum ua tau raws li Shore hardness (Hs) ntawm 70 lossis siab dua (sib npaug rau Mohs hardness 6-7). Qhov no ua kom ntseeg tau tias tiv taus kev hnav thiab kev hloov pauv hauv qab kev ntxhov siab ntev--ntau tshaj qhov nyuaj ntawm cov hlau cam khwb cia (Hs 40-50) lossis cov pob zeb marble ib txwm (Hs 30-40).
- Kev Sib Npaug ntawm Cov Qauv: Cov granite yuav tsum muaj cov qauv minerals uas tuab thiab sib npaug uas tsis muaj qhov tawg sab hauv, qhov hws, lossis cov minerals uas loj dua 0.5 hli. Qhov no zam kev ntxhov siab hauv zos thaum lub sijhawm ua lossis siv, uas yuav ua rau poob qhov tseeb.
- Kev Laus Ntuj: Cov granite nyoos yuav tsum tau laus ntuj tsawg kawg yog 5 xyoos ua ntej ua tiav. Cov txheej txheem no tso tawm tag nrho cov kev ntxhov siab sab hauv, kom ntseeg tau tias cov khoom tiav lawm tsis hloov pauv vim qhov kub thiab txias hloov pauv lossis cov av noo ib puag ncig.
1.2 Kev Siv Tshuab Ua Haujlwm
ZHHIMG cov khoom granite yog tsim los ntawm kev ua haujlwm ntau kauj ruam kom ua tau raws li qhov yuav tsum tau ua:
- Kev Txiav Txim Siab: Cov pob zeb granite nyoos raug txiav ua cov pob zeb tsis zoo raws li cov duab kos 2D/3D uas cov neeg siv khoom muab (txhawb nqa cov qauv nyuaj xws li cov qhov, cov qhov, thiab cov tes tsho hlau uas muab tso rau hauv).
- Kev Sib Tsoo Kom Tseeb: Cov tshuab sib tsoo CNC (nrog qhov tseeb ntawm ± 0.001mm) yog siv los ua kom zoo dua qhov chaw, ua tiav qhov yuam kev ntawm ≤0.003mm / m rau cov chaw tseem ceeb.
- Kev Khawb thiab Qhov: Cov cuab yeej pob zeb diamond siab raug siv rau kev khawb (qhov qhov raug ± 0.01 hli) thiab qhov, kom ntseeg tau tias muaj kev sib raug zoo nrog cov khoom siv sib dhos (piv txwv li, cov hlau qhia, cov ntsia hlau).
- Kev Kho Qhov Chaw: Siv cov tshuaj nplaum uas tsis muaj tshuaj lom rau cov khoom noj kom txo qhov nqus dej (mus txog ≤0.15%) thiab txhim kho kev tiv thaiv xeb—tsis cuam tshuam rau cov khoom uas tsis yog hlau nplaum.
2. Cov yam ntxwv tseem ceeb ntawm Granite Cheebtsam: Vim li cas lawv thiaj ua tau zoo dua li cov khoom siv ib txwm muaj
Cov khoom siv granite muaj cov txiaj ntsig tshwj xeeb tshaj li hlau (hlau cam khwb cia, hlau) lossis cov khoom siv hluavtaws, ua rau lawv tsis tseem ceeb hauv cov txheej txheem kho tshuab precision:
2.1 Kev Ntsuas Tseeb thiab Kev Ruaj Ntseg Zoo Tshaj Plaws
- Kev Khaws Cia Kom Ruaj Khov Mus Ib Txhis: Tom qab kev laus ntuj thiab kev ua tiav zoo, cov khoom granite tsis muaj kev hloov pauv yas. Lawv qhov tseeb ntawm qhov ntev (piv txwv li, qhov tiaj tus, qhov ncaj) tuaj yeem khaws cia tau ntau tshaj 10 xyoo nyob rau hauv kev siv ib txwm muaj - tshem tawm qhov xav tau rov kho dua ntau zaus.
- Cov Coefficient Thermal Expansion Qis: Granite muaj cov coefficient linear expansion tsuas yog 5.5 × 10⁻⁶ / ℃ (1/3 ntawm cov hlau cam khwb cia). Qhov no txhais tau tias muaj kev hloov pauv me me txawm tias nyob rau hauv cov chaw ua haujlwm nrog kev hloov pauv kub (piv txwv li, 10-30 ℃), kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov.
2.2 Cov Khoom Siv Kho Tshuab Zoo Tshaj Plaws
- Kev Tiv Thaiv Kev Hnav Siab: Cov pob zeb quartz thiab feldspar hauv granite muab kev tiv thaiv kev hnav zoo heev - 5-10 npaug ntau dua li hlau cam khwb cia. Qhov no yog qhov tseem ceeb rau cov khoom xws li cov cuab yeej siv tshuab, uas nyiaj dhau kev sib txhuam swb ntau zaus.
- Lub Zog Siab Compressive: Nrog lub zog compressive ntawm 210-280MPa, cov khoom granite tuaj yeem tiv taus cov khoom hnyav (piv txwv li, 500kg / m² rau cov rooj ua haujlwm) yam tsis muaj kev hloov pauv - zoo tagnrho rau kev txhawb nqa cov tshuab loj precision.
2.3 Kev Nyab Xeeb & Kev Txij Nkawm Zoo
- Tsis Muaj Hlau Sib Nqus & Tsis Muaj Hluav Taws Xob: Ua ib yam khoom siv uas tsis yog hlau, granite tsis tsim cov teb sib nqus lossis ua hluav taws xob. Qhov no tiv thaiv kev cuam tshuam nrog cov cuab yeej ntsuas sib nqus (piv txwv li, cov cim qhia) lossis cov khoom siv hluav taws xob rhiab heev, ua kom ntseeg tau tias qhov ua haujlwm raug.
- Tsis Muaj Xeb & Tiv Thaiv Kev Xeb: Tsis zoo li hlau lossis hlau cam khwb cia, granite tsis xeb. Nws kuj tiv taus feem ntau cov kuab tshuaj hauv kev lag luam (piv txwv li, roj av, cawv) thiab cov kua qaub / alkali tsis muaj zog - txo cov nqi kho thiab ua kom lub neej ua haujlwm ntev.
- Kev Ruaj Ntseg Rau Kev Puas Tsuaj: Yog tias qhov chaw ua haujlwm raug khawb lossis cuam tshuam, nws tsuas yog tsim cov qhov me me, tsis muaj qhov burrs lossis cov npoo siab. Qhov no zam kev puas tsuaj rau cov khoom ua haujlwm raug thiab tsis ua rau qhov tseeb ntawm kev ntsuas - tsis zoo li cov hlau, uas tuaj yeem tsim cov kev hloov pauv uas yuav tsum tau rov sib tsoo.
2.4 Kev Txij Nkawm Yooj Yim
Cov khoom siv granite xav tau kev saib xyuas tsawg kawg nkaus:
- Kev ntxuav txhua hnub tsuas yog xav tau daim ntaub mos mos uas muab tso rau hauv cov tshuaj ntxuav tsis muaj zog (tsis txhob siv cov tshuaj ntxuav uas muaj kua qaub/alkaline).
- Tsis tas yuav siv roj pleev xim, pleev xim, lossis kho xeb—txuag lub sijhawm thiab cov neeg ua haujlwm rau cov pab pawg kho lub Hoobkas.

4. Cov Lus Nug Feem Ntau: Cov Lus Nug Txog Cov Cheebtsam Granite
Q1: Cov khoom granite puas hnyav dua li cov khoom siv hlau cam khwb cia?
A1: Yog—granite muaj qhov ceev ntawm 2.6-2.8g/cm³ (me ntsis siab dua li cov hlau cam khwb cia 7.2g/cm³ tsis yog, kho kom raug: cov hlau cam khwb cia ceev yog ~7.2g/cm³, granite yog ~2.6g/cm³). Txawm li cas los xij, granite qhov kev nruj dua txhais tau tias cov qauv tsim nyias dua, sib dua tuaj yeem ua tiav qhov ruaj khov zoo ib yam li cov khoom hlau cam khwb loj.
Q2: Cov khoom granite puas siv tau rau sab nraum zoov lossis qhov chaw muaj av noo ntau?
A2: Yog—ZHHIMG cov khoom granite raug kho tshwj xeeb kom tsis txhob ntub dej (cov khoom siv foob ntawm qhov chaw) kom txo qhov nqus dej kom txog ≤0.15%. Lawv tsim nyog rau cov chaw ua haujlwm uas muaj av noo, tab sis tsis pom zoo kom ua haujlwm sab nraum zoov ntev (rau nag/hnub).
Q3: Nws siv sijhawm ntev npaum li cas los tsim cov khoom granite tshwj xeeb?
A3: Rau cov qauv tsim qauv (piv txwv li, cov rooj ua haujlwm plaub fab), kev tsim khoom siv sijhawm 2-3 lub lis piam. Rau cov qauv nyuaj (nrog ntau lub qhov / qhov), lub sijhawm ua khoom yog 4-6 lub lis piam - suav nrog kev sim khoom siv thiab kev ntsuas qhov tseeb.
