Kev ruaj ntseg tshuaj nyob rau hauv kev soj ntsuam: Puas Precision Granite Cheebtsam tiv thaiv acid thiab alkali corrosion?

Lub Metrology Dilemma: Qhov tseeb vs. Ib puag ncig

Rau cov chaw tsim khoom ntawm cov khoom siv semiconductor, kev sib koom tes ntsuas tshuab (CMMs), thiab cov tshuab laser siab heev, granite precision platform yog lub hauv paus ntawm qhov tseeb qhov tseeb. Cov lus nug tshwm sim thiab tseem ceeb tshwm sim nyob rau hauv ib puag ncig uas muaj cov dej txias, tshuaj ntxuav, lossis cov txheej txheem tshuaj: Puas yog lub hauv paus no tiv taus tshuaj tua kab mob, thiab qhov tseem ceeb tshaj, puas yuav cuam tshuam nws cov sub-micron lossis nanometer flatness?

Ntawm ZHHIMG®, Quad-Certified ntiaj teb no tus thawj coj nyob rau hauv ultra-precision manufacturing, peb cia siab rau cov qib siab tshaj plaws ZHHIMG® Dub Granite xa cov khoom nrog cov ntaub ntawv ruaj khov thiab ceev. Peb cov lus teb yog qhov tseeb: Precision granite muaj kev tiv thaiv zoo rau cov tshuaj feem ntau, tab sis kev tswj hwm nanometer flatness yuav tsum tau ceev faj txog kev tswj hwm ib puag ncig thiab cov txheej txheem nruj.

Kev Tshawb Fawb Tom Qab Granite Qhov Kev Ruaj Ntseg

Granite yog lub pob zeb uas tsis muaj zog uas feem ntau muaj cov tshuaj lom neeg tsis muaj zog silicate: quartz, feldspar, thiab mica.

1. Acid Resistance: Granite feem ntau tsis cuam tshuam los ntawm cov kua qaub tsis muaj zog (piv txwv li, vinegar, tshuaj ntxuav me me) vim nws cov ntsiab lus quartz siab (SiO2). Tsis zoo li marble, uas yog tsim los ntawm calcium carbonate (CaCO3) thiab yooj yim reacts nrog acid, granite yog heev resilient.
2. Alkali Resistance: Granite feem ntau ruaj khov thaum raug rau cov tshuaj alkali me me.

Txawm li cas los xij, tsis muaj pob zeb ntuj yog tiag tiag impervious. Cov kua qaub muaj zog (xws li Hydrofluoric Acid) thiab muaj zog, muaj zog alkalis tuaj yeem, dhau sijhawm, etch saum npoo los yog tshuaj lom neeg hloov cov feldspar minerals hauv pob zeb.

Lub Hidden hem rau Ultra-Precision

Nyob rau hauv lub ntiaj teb no ntawm ultra-precision, qhov tseeb yog ntsuas nyob rau hauv 175,000 nanometers, txawm microscopic tshuaj etching los yog saum npoo hloov ua ib qho kev puas tsuaj yuam kev.

Cov tshuaj reagents cuam tshuam qhov tseeb ntawm ob txoj hauv kev tseem ceeb:

1. Surface Topography Erosion: Tshuaj tua kab mob tsim microscopic pits, pores, los yog npub me ntsis (etching) ntawm polished granite nto. Qhov kev yaig me me no, pom tsis pom ntawm qhov muag liab qab, txaus los ua txhaum txoj cai nruj nruj ntawm Qib AA lossis Laboratory Qib platforms. Thaum siv raws li kev siv dav hlau metrology, cov kev hloov pauv saum toj no qhia txog kev ntsuas qhov tsis paub tseeb thiab cuam tshuam qhov rov ua dua ntawm cov cuab yeej so ntawm qhov chaw.
2. Cov kab mob sib kis thiab Micro-Porosity: Cov tshuaj lom neeg uas nyob lossis nkag mus rau lub pob zeb qhov porosity tsawg tuaj yeem nqus tau thiab khaws cov dej noo lossis cua sov. Qhov no tsim cov thermal gradients hauv zos los yog hygroscopic expansion, ua rau thermal distortion los yog o me ntsis destabilizes tag nrho cov platform geometry.

ZHHIMG® Advantage: Engineered Stability

ZHHIMG® hais txog qhov kev sib tw no los ntawm kev siv cov khoom ntiag tug thiab cov txheej txheem tsim khoom:

• Superior Density: Peb ZHHIMG® Dub Granite boasts qhov tshwj xeeb ntom ntom ntawm ≈3100 kg / m3. Cov khoom siv uas tsis tshua muaj porosity ib txwm muaj kev tiv thaiv zoo rau kev nkag mus rau cov kua dej piv rau qis qis lossis cov xim sib dua-xim granites, ua ib qho kev nruj dua tiv thaiv cov tshuaj lom neeg.
• Tswj Ib puag ncig: Txhua qhov kev sib tsoo thiab kev ntsuas tseem ceeb tshwm sim hauv peb qhov kev mob siab rau 10,000 m2 qhov ntsuas kub thiab av noo-tswj, txo qhov cuam tshuam ib puag ncig uas feem ntau ua rau muaj tshuaj lom neeg ntau ntxiv.

Kev saib xyuas yog yuav tsum tau ua rau Qib Kev Ntsuas

Txhawm rau kom ntseeg tau tias koj ZHHIMG® Precision Granite Platform tswj nws cov ntawv pov thawj flatness, peb cov kws tshaj lij pom zoo ua raws li cov txheej txheem saib xyuas no:

1. Kev Soj Ntsuam Tam Sim No: Tam sim ntawd so cov tshuaj lom, tshwj xeeb tshaj yog cov kua qaub (txawm tias kas fes lossis dej qab zib) lossis cov kuab tshuaj muaj zog, siv cov ntaub mos mos, tsis muaj abrasive.
2. Siv Cov Khoom Siv Tshwj Xeeb: Tsuas yog siv cov tshuaj ntxuav tshwj xeeb uas tsim los rau cov nplais granite saum npoo (feem ntau cawv lossis acetone-based). Tsis txhob siv cov tshuaj tua kab mob hauv tsev, tshuaj dawb, lossis tshuaj tua kab mob acidic / alkaline, vim tias cov no tuaj yeem tshem tawm cov tshuaj tiv thaiv kev tiv thaiv thiab ua kom du.
3. Tiv Thaiv Kev Tiv Thaiv Ntev: Tsis txhob tso cov tshuaj saturated rags, qhib lub raj mis ntawm reagents, lossis cov khoom siv hlau nrog cov tshuaj residue ncaj qha rau ntawm granite nto rau lub sijhawm ntev.

Los ntawm kev sib koom ua ke ZHHIMG® cov khoom siv zoo tshaj plaws thiab kev tsim kev ncaj ncees nrog kev ceev faj, engineers tuaj yeem tso siab rau lawv cov precision granite hauv paus kom nyob ruaj khov thiab tsis muaj zog, txawm tias nyob rau hauv qhov nyuaj tshaj plaws kev lag luam ib puag ncig.
