Ukunemba kwamapulatifomu e-granite kudlala indima ebalulekile ekuqinisekiseni ukuthi izilinganiso ziyaphindaphindeka ezinhlotsheni ezahlukene zezimboni nezesayensi. Ukunemba kwedekhi ye-granite kubhekisela ekhonweni layo lokugcina ubukhulu obuhambisanayo nobunembile, obuyisicaba, kanye nokuqina. Lokhu kunemba kuthinta ngqo ukuthembeka kanye nokuvumelana kwezilinganiso epulatifomu.
I-Granite iyindlela ethandwayo yokusetshenziswa kwe-metrology kanye nokulinganisa ngenxa yokuqina kwayo kanye nokumelana nokushintshashintsha kwezinga lokushisa. Ukunemba kwamadekhi e-granite kufezwa ngenqubo yokukhiqiza ngokucophelela, okuholela endaweni ebushelelezi, eyisicaba engenamaphutha amaningi. Leli zinga lokunemba libalulekile ekuqinisekiseni ukulinganiswa okuhambisanayo nokuphindaphindekayo epulatifomu.
Ukuthamba kwepulatifomu yegranite kubaluleke kakhulu ekulinganisweni okunembile. Noma yikuphi ukuphambuka noma ukungalingani ebusweni bepulatifomu kuzoletha amaphutha ekulinganisweni, okubangela ukungalingani nokunciphisa ukuphindaphindeka. Ukunemba kwepulatifomu yegranite kuqinisekisa ukuthi ubuso bulingana futhi buyisicaba, okuvumela ithuluzi lokulinganisa ukuthintana okunembile nokungaguquguquki nobuso.
Ngaphezu kwalokho, ukuzinza kwepulatifomu yegranite kunegalelo ekunembeni kwayo kanjalo nokuphindaphindeka kwezilinganiso. Ukumelana kwepulatifomu nokudlidliza kanye nokuguquguquka kuqinisekisa ukuthi ukunemba kobukhulu kuyagcinwa ngisho nasezindaweni zezimboni ezishintshashintshayo. Lokhu kuzinza kubalulekile ekufezeni izilinganiso ezithembekile neziphindaphindwayo, ikakhulukazi ezisetshenzisweni ezinembe kakhulu njengokukhiqiza i-semiconductor, amalabhorethri e-metrology, kanye nomshini wokulungisa ngokunemba.
Ngamafuphi, ukunemba kwepulatifomu yegranite kunegalelo ngqo ekuphindaphindweni kokulinganisa ngokuhlinzeka ngomphezulu wokulinganisa ozinzile, oyisicaba, nongaguquguquki. Lokhu kunemba kuqinisekisa ukuthi izilinganiso ezithathwe epulatifomu zithembekile, ziyaguquguquka futhi azinawo amaphutha ngenxa yokungahambi kahle komphezulu noma ukungazinzi. Ngenxa yalokho, imboni nesayensi zithembele ekunembileni kwamapulatifomu egranite ukuze kufezwe izilinganiso eziqondile neziphindaphindayo ezibalulekile ekulawulweni kwekhwalithi, ocwaningweni nasekuthuthukisweni.
