Ukuzinza Kwamakhemikhali Ngaphansi Kokucutshungulwa: Ingabe Izingxenye Zegwadle Eqondile Zimelana Ne-Acid Nokugqwala Kwe-alkali?

I-Metrology Dilemma: Ukunemba vs. Imvelo

Kubakhiqizi bezinto zokusebenza ze-semiconductor, imishini yokukala edidiyelwe (ama-CMM), nezinhlelo ze-laser ezithuthukisiwe, inkundla yokunemba yegwadle iyisisekelo sokunemba kobukhulu. Umbuzo ovamile nobalulekile uphakama ezindaweni ezihlanganisa izinto ezipholile, izinto zokuhlanza, noma amakhemikhali okucubungula: Ingabe lesi sisekelo siyamelana nokuhlaselwa kwamakhemikhali, futhi okubaluleke nakakhulu, ukuchayeka kuyolimaza i-sub-micron noma i-nanometer flatness?

Kwa-ZHHIMG®, umholi wembulunga yonke Oqinisekiswe I-Quad-Certified ekukhiqizeni ukunemba okuphezulu, sithembele kuzinga eliphakeme kakhulu le-ZHHIMG® Black Granite ukuletha izingxenye ezinokuqina nokuminyana okubhaliwe. Impendulo yethu iqinisekile: Igwagwagwa elinembayo linikeza ukumelana okuhle kakhulu namakhemikhali avamile, kodwa ukugcina ukukhanya kwe-nanometer kudinga ukulawulwa ngokucophelela kwemvelo kanye nemithetho elandelwayo eqinile.

Isayensi Engemuva Kokuqina Kwe-Granite

I-Granite iyidwala elivuthayo elihlanganiswe ngokuyinhloko ngamaminerali e-silicate angenayo amakhemikhali: i-quartz, i-feldspar, ne-mica.

1. I-Acid Resistance: Igranite ayithinteki kakhulu ama-asidi abuthakathaka (isb, uviniga, ama-ejenti okuhlanza amaphakathi) ngenxa yokuqukethwe kwayo okuphezulu kwe-quartz (SiO2). Ngokungafani ne-marble, eyakhiwe nge-calcium carbonate (CaCO3) futhi isabela kalula nge-asidi, i-granite iyakwazi ukuqina.
2. I-Alkali Resistance: I-Granite ivamise ukuzinza lapho ibhekene nezixazululo eziningi ze-alkali ezithambile.

Nokho, alikho itshe lemvelo elingangenwa ngempela. Ama-acids aqinile (afana ne-Hydrofluoric Acid) nama-alkali aqinile, agxilile angakwazi, ngokuhamba kwesikhathi, afake phezulu noma aguqule ngamakhemikhali amaminerali e-feldspar ngaphakathi kwetshe.

Usongo Olufihliwe Loku-Ultra-Precision

Ezweni lokunemba okuphezulu, lapho ukunemba kukalwa ngamakhulu ama-nanometers, ngisho nokucwiliswa kwamakhemikhali okuncane kakhulu noma ukushintsha kwendawo kwenza iphutha elikhulu.

Ama-Chemical reagents athinta ukunemba ngezindlela ezimbili ezibalulekile:

1. Ukuguguleka Kwendawo Engaphansi: Ukuhlasela kwamakhemikhali kudala imigodi emincane, izimbotshana, noma amachashaza abuthuntu (etching) endaweni epholishiwe yegwadle. Lokhu kuguguleka okuncane, okungabonakali ngeso lenyama, kwanele ukwephula ukubekezelela okuqinile kweBanga AA noma iBanga leLabhorethri. Uma isetshenziswa njengendiza eyinkomba ye-metrology, lezi zinguquko zesimo sendawo zethula ukungaqiniseki kokulinganisa futhi zibeke engcupheni ukuphindaphinda kwamathuluzi ahlezi phezulu.
2. Ukungcoliswa kanye Ne-Micro-Porosity: Izinsalela zamakhemikhali ezihlala noma ezingena ekuqineni okuncane kwetshe zingamunca futhi zigcine umswakama noma ukushisa. Lokhu kudala ama-thermal gradients asendaweni noma ukunwetshwa kwe-hygroscopic, okuholela ekuhlanekezeleni okushisayo noma ukuvuvukala okuncane okwenza kungabi nazinzo i-geometry yeplathifomu iyonke.

I-ZHHIMG® Advantage: Engineered Stability

I-ZHHIMG® ibhekana nale nselele ngokusebenzisa izinto zobunikazi kanye nezinqubo zokukhiqiza:

• Ukuminyana Okuphakeme: I-ZHHIMG® Black Granite yethu iziqhayisa ngokuminyana okukhethekile okungu-≈3100 kg/m3. Lokhu okune-porosity ephansi ngokwemvelo kunikeza ukumelana okuthuthukisiwe ekungeneni koketshezi uma kuqhathaniswa nokuminyana okuphansi noma ama-granite anombala okhanyayo, okwenza umgoqo oqinile ngokumelene nokugxambukela kwamakhemikhali.
• Indawo Elawulwayo: Konke ukugaya nokulinganisa okubalulekile kwenzeka ngaphakathi kwendawo yethu yokushisa engu-10,000 m2 kanye nomswakama olawulwayo, okunciphisa izici zemvelo ezivame ukwandisa imiphumela yamakhemikhali.

Ukunakekela Kuyimpoqo Yebanga Le-Metrology

Ukuqinisekisa ukuthi i-ZHHIMG® Precision Granite Platform yakho igcina isicaba sayo esiqinisekisiwe, ochwepheshe bethu batusa ukubambelela ngokuqinile kule mihlahlandlela yokunakekela:

1. Ukuhlanza Ngokushesha Ukuchitheka: Sula ngokushesha noma yikuphi ukuchitheka kwamakhemikhali, ikakhulukazi ama-asidi (ngisho nekhofi noma i-soda) noma izincibilikisi ezinamandla, usebenzisa indwangu ethambile, engancibiliki.
2. Sebenzisa Izihlanzi Ezikhethekile: Sebenzisa kuphela izihlanzi ezakhelwe ngokuqondile amapuleti angaphezulu egwadle (ngokuvamile asuselwa kutshwala noma asekelwe ku-acetone). Gwema izihlanzi zasendlini, i-bleach, noma izibulala-magciwane ezine-asidi/ezine-alkali, njengoba lezi zingakhumula noma yiziphi izinto ezivikelayo futhi zenze isiphetho sibe buthuntu.
3. Vimbela Ukuthintana Isikhathi Eside: Ungalinge ushiye amanikiniki agcwele amakhemikhali, amabhodlela avuliwe ama-reagents, noma izingxenye zensimbi ezinensalela yamakhemikhali ngokuqondile endaweni yegwadle isikhathi eside.

Ngokuhlanganisa isayensi yezinto ezibonakalayo ephakeme ye-ZHHIMG® kanye nobuqotho bokukhiqiza nokugcinwa okuqaphile, onjiniyela bangathemba izisekelo zabo zegwadle ezinembayo ukuthi zizohlala zizinzile futhi zingasebenzi ngamakhemikhali, ngisho nasezindaweni zezimboni eziyinselele kakhulu.
