Ukuzinza kweMichiza Phantsi kokuHlolwa: Ngaba iMicimbi yeGranite eChanekileyo iXhaxa i-Acid kunye ne-Alkali Corrosion?

Ingxaki yeMetrology: Ukuchaneka xa kuthelekiswa nokusingqongileyo

Kubenzi bezixhobo ze-semiconductor, ukulungelelanisa oomatshini bokulinganisa (i-CMMs), kunye neenkqubo ze-laser eziphambili, i-platform ye-granite yokuchaneka isiseko sokuchaneka kwe-dimensional. Umbuzo oqhelekileyo nobalulekileyo uvela kwindawo equka izinto ezipholileyo, ii-agent zokucoca, okanye iikhemikhali zenkqubo: Ngaba esi siseko siyaxhathisa kuhlaselo lwekhemikhali, kwaye okona kubaluleke kakhulu, kuya kubhenca kujongeka phantsi i-sub-micron okanye i-nanometer flat?

E-ZHHIMG®, inkokeli yehlabathi eneSiqinisekiso seQuad kwimveliso echanekileyo, sithembele kwelona bakala liphezulu le-ZHHIMG® Black Granite ukuhambisa amacandelo anozinzo kunye noxinaniso olubhaliweyo. Impendulo yethu iqinisekile: Igranite echanekileyo inika ukuchasana okugqwesileyo kwezona khemikhali zixhaphakileyo, kodwa ukugcina i-nanometer flat kufuna ulawulo olululo lwendalo esingqongileyo kunye neeprothokholi ezingqongqo.

ISayensi eNgemva koKunyamezela kweGranite

Igranite lilitye elivuthayo eliqulunqwe ziiminerali ze-silicate zekhemikhali: iquartz, feldspar, kunye ne-mica.

1. Ukumelana ne-Acid: I-Granite ayichatshazelwa kakhulu yi-acids ebuthakathaka (umzekelo, iviniga, i-agent ecocekileyo yokucoca) ngenxa yomxholo wayo ophezulu we-quartz (SiO2). Ngokungafaniyo nemarble, eyenziwe nge-calcium carbonate (CaCO3) kwaye isabela ngokulula nge-asidi, igranite yomelele kakhulu.
2. Ukumelana ne-alkali: Igranite iyazinza ngokubanzi xa iboniswe kwizisombululo ezininzi zealkali.

Nangona kunjalo, akukho litye lendalo elingenakukwazi ukungena. I-acids ezinamandla (njenge-Hydrofluoric Acid) kunye ne-alkali eqinile, egxininisiweyo, ngokuhamba kwexesha, ifake umphezulu okanye iguqule iikhemikhali i-feldspar minerals ngaphakathi kwelitye.

Usongelo olufihlakeleyo kwi-Ultra-Precision

Kwihlabathi le-ultra-precision, apho ukuchaneka kulinganiswa ngamakhulu e-nanometers, kunye nokuthungwa kweekhemikhali ezincinci okanye ukuguqulwa komphezulu kwenza impazamo enkulu.

Ii-reagents zemichiza zichaphazela ukuchaneka ngeendlela ezimbini ezibalulekileyo:

1. Ukhukuliseko lweTografi yoMphezulu: Uhlaselo lwekhemikhali ludala imingxuma emikroskopu, imingxuma emincinane, okanye amabala abuthuntu (ukukrolwa) kumphezulu wegranite opolishiweyo. Olu khukuliseko luncinci, olungabonakaliyo ngeso lenyama, lwanele ukuba luphule ukunyamezela kwe-flatness engqongqo yeBanga le-AA okanye iBanga leBanga leLebhu. Xa isetyenziswa njengenqwelo-moya yesalathiso se-metrology, olu tshintsho lwemo yomhlaba lwazisa ukungaqiniseki komlinganiselo kwaye lubeke esichengeni ukuphinda-phinda kwezixhobo eziphumle phezu komhlaba.
2. Ungcoliseko kunye neMicro-Porosity: Intsalela yekhemikhali ethi ihlale okanye ingene kubuncinci belitye inokufunxa kwaye igcine ukufuma okanye ubushushu. Oku kudala ukuthambeka kwe-thermal yendawo okanye ukwandiswa kwe-hygroscopic, okukhokelela ekugqwethekeni kwe-thermal okanye ukudumba okuncinci okuphazamisa i-geometry yeqonga lilonke.

I-ZHHIMG® i-Advanteji: Uzinzo lobuNjineli

I-ZHHIMG® ijongana nalo mngeni ngokusebenzisa izixhobo zobunikazi kunye neenkqubo zokuvelisa:

• Uxinaniso oluPhezulu: I-ZHHIMG® yethu yeGranite emnyama iqhayisa ngokuxinana okukhethekileyo kwe-≈3100 kg/m3. Esi sixhobo sine-porosity ephantsi ngokwendalo sinika ukuxhathisa okongeziweyo ekungeneni kolwelo xa kuthelekiswa noxinano olusezantsi okanye iigraniti ezinombala okhaphukhaphu, zenza umqobo ongqongqo ngokuchasene nokungena kweekhemikhali.
• Imekobume eLawulwayo: Konke ukucola okubalulekileyo kunye nemilinganiselo yenzeka kwindawo yethu ezinikeleyo eyi-10,000 m2 yobushushu kunye nesixhobo solawulo lokufuma, sithomalalisa iimeko zokusingqongileyo ezidla ngokunyusa iziphumo zekhemikhali.

Ukugcinwa kunyanzelekile kwiBanga leMetrology

Ukuqinisekisa ukuba iPlatform yakho ye-ZHHIMG® Precision Granite igcina iplatifomu yayo eqinisekisiweyo, iingcali zethu zincoma ukuthotyelwa okungqongqo kwezi zikhokelo zokhathalelo:

1. Ukucoca ngokukhawuleza ukuchitheka: Sula ngokukhawuleza nakuphi na ukuchitheka kweekhemikhali, ngakumbi i-acids (nokuba ikofu okanye i-soda) okanye izinyibilikisi ezinamandla, usebenzisa ilaphu elithambileyo, elingena-abrasive.
2. Sebenzisa izicoci eziZodwa: Sebenzisa kuphela izicoci ezenzelwe ngokukodwa iipleyiti zegranite zomhlaba ezichanekileyo (ngokuqhelekileyo utywala okanye i-acetone-based). Ziphephe izicoci zasemakhaya, iblitshi, okanye izibulali-ntsholongwane ezineasidi/zealkaline, njengoko ezi zinokukhulula naziphi na izitywini ezikhuselayo kwaye zibe buthuntu isiphelo.
3. Thintela uQhagamshelwano oluDala: Ungaze ushiye amalaphu azaliswe ziikhemikhali, iibhotile ezivulekileyo zeerejenti, okanye izinto zentsimbi ezinentsalela yeekhemikhali ngokuthe ngqo kumphezulu wegranite ixesha elongeziweyo.

Ngokudibanisa inzululwazi yezinto eziphezulu ze-ZHHIMG® kunye nokuthembeka kwemveliso kunye nokugcinwa okuphaphileyo, iinjineli zinokuthembela ukuchaneka kweziseko zabo ze-granite ukuze zihlale zizinzile kwaye zingasebenzi ngokwekhemikhali, nakwiindawo zemizi-mveliso ezinomngeni.
