Iigeyiji zeGranite ezinxuseneyo zizixhobo zokulinganisa ezichanekileyo, kwaye imfezeko yobuso bazo obuthe tyaba buchaphazela ngokuthe ngqo ukuchaneka komlinganiselo. Ukucocwa ngokungafanelekanga okanye ukuphatha kakuhle kunokubangela imikrwelo, ukubola, okanye utshintsho olufihlakeleyo kwiipropathi zelitye, luphazamise ukuchaneka kwalo. Ukugcina ezi zixhobo kufuna ingqalelo ngenyameko kwiindlela zokucoca, izinto eziphathekayo, kunye neemeko zokusingqongileyo.
Ngaphambi kokucoca, kubalulekile ukulungisa indawo elawulwayo, engenathuli. I-gauge kufuneka ifakwe kwindawo eyomileyo, ezimeleyo yokukhusela iincinci ezinomoya, i-shavings yensimbi, okanye i-oyile eseleyo ekungcoleni komhlaba. Zonke izixhobo zokucoca, kuquka amalaphu athambileyo, izipontshi, kunye neebhrashi, kufuneka zicocwe ngokucokisekileyo kwaye zihlolwe ukuze kususwe naziphi na iintsinga ezixengayo okanye amasuntswana aqinileyo anokukrwela igranite. Ukuqonda uhlobo lwamabala-nokuba lunamafutha, i-asidi, okanye i-pigment-based-kwanceda ukugqiba eyona ndlela yokucoca isebenzayo.
Ukukhetha i-arhente yokucoca efanelekileyo kubaluleke ngokulinganayo. Igranite inochuku kwiiasidi kunye nealkaline ezomeleleyo, ngoko ke kufuneka kusetyenziswe kuphela izicoci ezingathathi hlangothi ezine pH phakathi kwe 6 kunye ne 8. Izicoci zendlu ezinobundlobongela, ezifana nezo zinesodium hydroxide, kufuneka ziphetshwe, njengoko zingonakalisa umgangatho welitye. Kumabala anenkani, izicoci zamatye ezikhethekileyo zingasetyenziswa emva kokuvavanya indawo encinci, engabonakaliyo kangangeeyure ezingama-24 ukuqinisekisa ukuba akukho lumbala okanye ukulahleka kweglosi kwenzeka. Ii-agent ezahlukeneyo zokucoca akufanele neze zixutywe, njengoko ukuphendula kweekhemikhali kunokuvelisa iigesi ezinobungozi okanye ukunciphisa ukusebenza kokucoca.
Ngexesha lokucoca, ukugcina umkhombandlela wokusula ohambelanayo kunye noxinzelelo oluthambileyo kubalulekile. Soloko usula kwicala elinye elihambelana nebrashi okanye ilaphu ukunqanda imikrwelo emincinci. Iibrashi ezithambileyo kufuneka zisetyenziswe kwimiphetho ukukhusela ii-chamfers. Emva kokucoca, hlambulula ngokucokisekileyo ngamanzi ahlanjululweyo okanye ahlanjululweyo ukukhusela iidiphozithi zamaminerali kwaye zome usebenzisa iingubo ezingenazintambo okanye umoya wendalo. Ubushushu okanye ukukhanya kwelanga okuthe ngqo kufuneka kuphetshwe, njengoko utshintsho olukhawulezileyo lobushushu lunokubangela ukuqhekeka.
Ingqwalasela ekhethekileyo kufuneka inikwe amabala angxamisekileyo kunye nokugcinwa kwexesha elide. Izinto ze-Acidic, ezifana nejusi yeziqhamo okanye iviniga, kufuneka zihlanjululwe ngokukhawuleza kwaye zingathathi hlangothi nge-ammonia ehlanjululweyo ngelixa unxibe iiglavu zokukhusela. Imikrwelo emincinci yentsimbi inokucolwa ngobunono ngomgubo ocoliweyo wamatye kwaye ivakale, kodwa umonakalo onzulu kufuneka uphathwe ngeenkonzo zobuchwephesha. Amabala aqhubekayo angena kumphezulu wegranite afuna ukucocwa okukhethekileyo kunye nonyango lwe-crystallization ukubuyisela ukukhanya kunye negloss.
Ukugcinwa okuqhubekayo kubalulekile ukuze kuqinisekiswe ukuchaneka kwexesha elide. Ukufaka isitywini esingena rhoqo emva kweenyanga ezintandathu kudala umqobo okhuselayo kumabala, ngaphandle kokuba umphezulu womile kwaye isitywini sifunxeka ngokulinganayo. Ukugcinwa ngokufanelekileyo kukwangundoqo; iigeyiji kufuneka ziphumle ngokuthe tye kwiimethi zerabha okanye izixhaso zomthi, zithintele ukudibana ngokuthe ngqo nentsimbi okanye umphezulu oqinileyo, kunye nokuguquguquka okulawulekayo kobushushu ngaphakathi ±5℃ kunye nokufuma okungaphantsi kwe-60%. Ukulinganisa ngamaxesha usebenzisa i-laser interferometers okanye amanqanaba ombane ayimfuneko ukuze kuqinisekiswe ukuba imigangatho yokulinganisa igcinwa. Nakuphi na ukutenxa okufunyenweyo kufuneka kubangele ukumiswa kwangoko kokusetyenziswa kunye nokulungiswa kobuchwephesha.
Ngokudibanisa ukucoca ngokucokisekileyo, ukusetyenziswa ngokuchanekileyo kweemveliso ezikhuselekileyo zamatye, ukuphatha ngokufanelekileyo, kunye nokugcinwa kwesiqhelo, ixesha lokuphila kunye nokuchaneka kwe-granite parallel gauges inokugcinwa ngokufanelekileyo. Kwimingeni enzima yokucoca okanye ukunakekelwa okukhethekileyo, ukubonisana nenkonzo yokugcinwa kwamatye ochwephesha kucetyiswa ngamandla ukukhusela umonakalo ongenakuguqulwa kwaye uqinisekise ukuchaneka okuqhubekayo kwimilinganiselo.
