Kukhazikika Kwama Chemical Pakufufuzidwa: Kodi Zida Zamtengo Wapatali Zamtengo Wapatali Zimakana Kuwonongeka Kwa Acid ndi Alkali?

The Metrology Dilemma: Zolondola motsutsana ndi Chilengedwe

Kwa opanga zida za semiconductor, makina oyezera (CMMs), ndi makina apamwamba a laser, nsanja yolondola ya granite ndiye maziko olondola kwambiri. Funso lodziwika komanso lofunikira limabuka m'malo okhala ndi zoziziritsa kukhosi, zoyeretsera, kapena mankhwala opangira mankhwala: Kodi mazikowa amalimbana ndi kuukira kwa mankhwala, ndipo koposa zonse, kuwonekera kungasokoneze kusalala kwa micron kapena nanometer?

Ku ZHHIMG®, mtsogoleri wapadziko lonse wotsimikiziridwa ndi Quad-Certified mu ultra-precision kupanga, timadalira ZHHIMG® Black Granite yapamwamba kwambiri kuti ipereke zigawo zomwe zimakhala zokhazikika komanso zolimba. Yankho lathu ndi lotsimikizika: Kulondola kwa granite kumapereka kukana kwamankhwala odziwika bwino, koma kukhalabe ndi nanometer flatness kumafuna kuwongolera bwino kwa chilengedwe ndi ndondomeko zokhwima.

Sayansi Yobwerera Kulimba kwa Granite

Granite ndi mwala woyaka moto womwe umapangidwa ndi minerals inert silicate: quartz, feldspar, ndi mica.

1. Kukaniza kwa Acid: Granite sakhudzidwa kwambiri ndi ma asidi ofooka (mwachitsanzo, vinyo wosasa, zoyeretsa pang'ono) chifukwa cha kuchuluka kwake kwa quartz (SiO2). Mosiyana ndi nsangalabwi, yomwe imapangidwa ndi calcium carbonate (CaCO3), ndipo imakhudzidwa mosavuta ndi asidi, granite imakhala yolimba kwambiri.
2. Kukaniza kwa Alkali: Granite nthawi zambiri imakhala yokhazikika ikakumana ndi ma alkali ochepa kwambiri.

Komabe, palibe mwala wachilengedwe womwe sungathe kutha. Ma acid amphamvu (monga Hydrofluoric Acid) ndi amphamvu, okhazikika a alkalis amatha, pakapita nthawi, amatulutsa pamwamba kapena kusintha mchere wa feldspar mkati mwa mwala.

Chiwopsezo Chobisika kwa Ultra-Precision

M'dziko lolondola kwambiri, momwe kulondola kumayezedwa mu mazana a nanometers, ngakhale kuyika kwamankhwala kosawoneka bwino kapena kusintha kwapamwamba kumakhala vuto lalikulu.

Chemical reagents zimakhudza kulondola m'njira ziwiri zovuta:

1. Kukokoloka kwa Pamwamba Pamwamba: Kuukira kwa Chemical kumapanga maenje ang'onoang'ono, ma pores, kapena madontho osawoneka bwino (zotsekemera) pamtunda wopukutidwa wa granite. Kukokoloka kochepa kumeneku, kosawoneka ndi maso, ndikokwanira kuphwanya kulolerana kwamphamvu kwa Grade AA kapena nsanja ya Laboratory Grade. Akagwiritsidwa ntchito ngati ndege yolozera za metrology, kusintha kwamawonekedwe kumabweretsa kusatsimikizika kwa muyeso ndikusokoneza kubwereza kwa zida zomwe zili pamwamba.
2. Kuipitsidwa ndi Micro-Porosity: Zotsalira za mankhwala zomwe zimakhazikika kapena kulowa pang'onopang'ono mwalawo zimatha kuyamwa ndikusunga chinyezi kapena kutentha. Izi zimapanga matenthedwe amtundu wamba kapena kukulitsa kwa hygroscopic, zomwe zimapangitsa kuti matenthedwe asokonezeke kapena kutupa pang'ono komwe kumapangitsa kuti geometry ya nsanja isokonezeke.

Ubwino wa ZHHIMG®: Engineered Stability

ZHHIMG® imathana ndi vutoli pogwiritsa ntchito zinthu zomwe zili ndi eni ake komanso njira zopangira:

• Kachulukidwe Kwambiri: ZHHIMG® Black Granite yathu ili ndi kachulukidwe kapadera ka ≈3100 kg/m3. Zinthu zotsika pang'onozi mwachilengedwe zimapereka kukana kulowa kwamadzimadzi poyerekeza ndi ma granite ocheperako kapena opepuka, kupanga chotchinga cholimba motsutsana ndi kulowerera kwamankhwala.
• Malo Olamuliridwa: Kugaya ndi kuyeza konse kofunikira kumachitika mkati mwa malo athu odzipereka a 10,000 m2 kutentha ndi chinyezi, kuchepetsa zinthu zachilengedwe zomwe nthawi zambiri zimakulitsa zotsatira zamankhwala.

Kukonza Ndikofunikira kwa Metrology Grade

Kuwonetsetsa kuti ZHHIMG® Precision Granite Platform yanu ikusungabe kutsika kwake kovomerezeka, akatswiri athu amalimbikitsa kutsatira mosamalitsa malangizo awa:

1. Kuyeretsa Mwamsanga: Pukutani nthawi yomweyo mankhwala aliwonse omwe atayika, makamaka ma asidi (ngakhale khofi kapena soda) kapena zosungunulira zamphamvu, pogwiritsa ntchito nsalu yofewa, yosatupa.
2. Gwiritsani Ntchito Zotsukira Zapadera: Gwiritsani ntchito zotsukira zokhazokha zopangidwira mbale za granite zapamwamba (nthawi zambiri mowa kapena acetone). Pewani zotsukira m'nyumba, bulichi, kapena mankhwala ophera tizilombo ta asidi kapena zamchere, chifukwa amatha kuchotsa zotchinga zilizonse ndikupangitsa kuti zisawonongeke.
3. Pewani Kulumikizana Kwanthawi yayitali: Osasiya nsanza zodzaza ndi mankhwala, mabotolo otsegula a reagents, kapena zida zachitsulo zomwe zimakhala ndi zotsalira zamakemikolo mwachindunji pamwamba pa granite kwa nthawi yayitali.

Mwa kuphatikiza sayansi yapamwamba ya ZHHIMG® ndi kukhulupirika kopanga ndikusamalira mwatcheru, mainjiniya amatha kukhulupirira kuti maziko awo olondola a granite azikhala okhazikika komanso opanda mankhwala, ngakhale m'malo ovuta kwambiri a mafakitale.
