I-Granite vs. Marble kwiZixhobo zokuQinisekisa: Kutheni ubuninzi kunye nozinzo kubalulekile

Ngena phantse kuyo nayiphi na ilabhoratri ye-metrology, igumbi le-CMM, okanye ifenitshala ye-semiconductor, kwaye uya kufumana ilitye elimnyama phantsi kwesixhobo. Kumntu ongaqeqeshwanga, i-granite kunye ne-marble zibukeka zinokutshintshana — zombini zilitye eliqingqiweyo, zombini zinokupholishwa zide zibe mhle, zombini zibukeka "ziqinile." Kwimveliso echanekileyo, loo nto ifana iphela kwangoko xa uqala ukulinganisa kwinqanaba le-micron.

Ubuninzi abuyonto yobuhle

I-Marble lilitye elitshintshayo elenziwe ngokuyintloko nge-calcite okanye i-dolomite ephinde yasetyenziswa. Isakhiwo sayo sekristale sithambile kwaye sinemingxuma xa sithelekiswa ne-granite e-igneous, eyenziwe yi-magma epholile kancinci kwaye ilawulwa ziiminerali eziqinileyo ezifana ne-quartz kunye ne-feldspar. Loo mahluko kwisakhiwo ubonakala ngokuthe ngqo kuxinano: i-granite emnyama esetyenziselwa iziseko ezichanekileyo idla ngokuba malunga ne-3,000–3,100 kg/m³, exineneyo kakhulu kunee-marble ezininzi zorhwebo.

Uxinano lubalulekile kuba luhambelana nokuqina kwangaphakathi kunye nokumelana nokurhubuluza — ukuguquka okucothayo nokusisigxina kwezinto ezidlula phantsi komthwalo oqhubekayo okanye ubunzima bazo. Ipleyiti yomphezulu wegranite exhasa i-umatshini wokulinganisa olungelelanisiweyo(CMM) okanye inkqubo yokuhlola i-optical kufuneka ihlale ithe tyaba kangangeminyaka, hayi iinyanga. Izinto ezinoxinano oluphantsi kunye nesakhiwo sangaphakathi esineembobo zinokuba lula ukutyibilika kancinci kancinci, ukufunxwa komswakama, kunye nokuqhekeka okuncinci phantsi komjikelo wobushushu.

Kutheni Abanye Abathengisi Bethatha Indawo Yemarble Nokuba Kunjalo?

Imarble ibiza kancinci kune-quarry nakwi-machine, kwaye ii-slabs ezigqityiweyo kunokuba nzima ukuzibona ngokucacileyo kwi-granite xa sele ipholishiwe yaza yadaywa mnyama. Kwimarike apho abathengi badla ngokungakwazi ukuvavanya uxinano okanye uzinzo lwexesha elide ngaphambi kokuba bayithenge, oku kudala indawo yokubhala iilebhile ngendlela engafanelekanga - ukuthengisa izinto ezisekwe kwimarble njengeziseko "zegranite". Isiphumo esisebenzayo asikuko ukuhlobisa; yinkqubo yokulinganisa elahlekelwa kancinci kukulinganiswa, rhoqo ngaphandle kwesizathu esicacileyo de imilinganiselo ephindaphindwayo iqale ukujika.

Yintoni Omele Uyihlole Ngaphambi Kokuthenga

Kwiinjineli ezichaza iziseko zegranite, ezinye iindlela zokuhlola zinceda ukwahlula igranite yokwenyani echanekileyo kwezinye ezikumgangatho ophantsi:

• Cela amanani oxinano, aqinisekiswe ngcono lilabhoratri yomntu wesithathu kunokuba kuqinisekiswe yidathasheet kuphela.
• Cela ukulandelelwa komlinganiselo — iipleyiti zomphezulu kufuneka zithunyelwe kunye nezatifikethi zokusicaba ezinokulandelelwa kwiziko lesizwe le-metrology.
• Hlola isakhiwo seenkozo phantsi kokwandiswa; igranite yokwenyani ibonakalisa ipateni yekristale erhabaxa, edibeneyo, ngelixa isakhiwo sekristale semarble sicolekile kwaye sifana ngakumbi.
• Jonga idatha yokwandiswa kobushushu, kuba i-granite's low and stability coefficient of thermal expansion sesinye sezizathu eziphambili zokuba ikhetheke kwizixhobo ezinobungcipheko obufana neeCMM kunye nee-optical benchs.

Njengoko ukwenziwa ngokuchanekileyo kuqhubekela phambili ekunyamezeleni okuqinileyo — ukuba tyaba kwinqanaba le-nanometer kwiiplate zomphezulu ngoku kuyafezekiswa — ukhetho lwezinto eziluhlaza luyeka ukuba yinto encinci kwaye luba yinto egqibayo ukuba isixhobo sihlala ixesha elingakanani sichanekile. Iinkampani ezifana ne-ZHHIMG, ezenza izinto zegranite kunye nezixhobo zokulinganisa kwisikali, zijonga ukuqinisekiswa koxinano njengenxalenye eqhelekileyo yokulawula umgangatho kuba umahluko phakathi kwesiseko esizinzileyo kunye neso sihamba kancinci rhoqo awubonakali de kube kade.
