Kwicandelo lokwenziwa kwezinto ngendlela echanekileyo kakhulu, ukugaywa nokupholishwa kweepleyiti zomphezulu wegranite kudlala indima ebalulekileyo ekumiseleni ukuba umphezulu uthambile, ukukhazimla, kunye nokuchaneka ngokubanzi. Nangona igranite yenye yezona zinto zendalo zinzima nezizinzileyo, ukufikelela kwinqanaba le-micrometer elifunekayo kusaxhomekeke ekukhetheni ngononophelo kunye nokusetyenziswa ngokuchanekileyo kwezinto zokupholisha kunye neearhente zokupholisha.
Ngexesha lenkqubo yokusila, ezi zinto zilulwelo kunye neearhente aziphembeleli nje kuphela amazinga okususwa kwezinto kodwa zikwachaphazela nokugqitywa komphezulu kunye nokuzinza kwexesha elide kweqonga legranite. Ukukhetha uhlobo olufanelekileyo kunye nokwakheka kubalulekile ukuze kufezekiswe iziphumo ezilungileyo kunye nokwandisa ubomi becandelo legranite elichanekileyo.
Kwizicelo zobungcali, ulwelo kunye neearhente ezisetyenziselwa ukugaya iqonga legranite ngokubanzi zahlulwe zibe ziindidi ezine ezisebenzayo: izicoci, ii-abrasives, ii-polishing agents, kunye nee-sealants.
Izicoci zisetyenziselwa ukususa ukungcola kunye neentsalela kumphezulu wegranite—ezifana neoyile, i-oxide, okanye uthuli olucolekileyo—ngaphambi nasemva kokusila. Izisombululo zokucoca eziqhelekileyo ziquka izicoci ze-pH ezingathathi cala, ii-agents ezithambileyo, okanye izicoci ze-alkaline. Xa usebenzisa izicoci zeekhemikhali, abaqhubi kufuneka balawule ukugxila kunye nexesha lokuvezwa ukuze bathintele ukugqwala okanye ukufiphala komphezulu wegranite.
Ii-abrasives zisebenza njengesixhobo esiphambili sokususa izinto. Iinkozo ezirhabaxa zisika kwaye zilinganise umphezulu wegranite ukuze kususwe iziphene ezincinci, imikrwelo, kunye nokungalingani. Izinto ezirhabaxa ezisetyenziswa kakhulu yi-alumina, i-silicon carbide, kunye neekhompawundi ze-silica ezicocekileyo kakhulu. Ukukhethwa kohlobo lwe-abrasives, ubungakanani be-particle, kunye noxinzelelo kuxhomekeke kubunzima begranite kunye nokuchaneka komphezulu okufunekayo. Ukugqiba kakuhle, ii-abrasives ezinobukhulu be-sub-micron particles zisetyenziselwa ukufikelela kwiindawo ezithe tyaba kakhulu ngaphakathi kwe-1–2 µm yokunyamezela ukuthamba.
Iiarhente zokupolisha ziyasetyenziswa emva kokusila ukuze kuphuculwe ukuthamba komphezulu kunye nokukhazimla. Kweli nqanaba, injongo ayikokususa izinto kodwa kukuphucula ubume bomphezulu omncinci. Iifomyula eziphambili ezisekwe kwi-polyurethane, iikhompawundi ze-acrylic, kunye ne-chromium oxide zihlala zisetyenziselwa ukuvelisa ukugqitywa okufana nesipili. Ibhalansi echanekileyo phakathi koxinzelelo, isantya, kunye nokwakheka kweearhente kubalulekile ekufezekiseni ukukhanya okufanayo ngaphandle kokuphazamisa ukuchaneka.
Okokugqibela, izitywini zisetyenziswa njengomaleko wokukhusela emva kokuba ukupolisha kugqityiwe. I-Granite ngokwayo iyakwazi ukumelana nokugqwala kunye nokutshintsha kobushushu, kodwa ukusebenzisa isitywini esifanelekileyo kuphucula ukumelana namanzi, ioyile, kunye nothuli ngelixa kugcina uzinzo lwe-optical kunye ne-mechanical yeqonga. Abavelisi abaziingcali badla ngokusebenzisa izitywini ezisekwe kwi-polymer okanye kwi-wax ukuqinisekisa ukhuseleko lwexesha elide, ngakumbi kwiindawo ezinomswakama ophezulu okanye zelebhu.
Xa besenza ukugaya nokupolisha i-granite, abaqhubi kufuneka baqinisekise ukuba ubushushu kunye nokufuma kusemgangathweni—ngesiqhelo yi-20 ± 1 °C—ukuthintela ukuguquka kobushushu. Ukusebenzisa amanzi acocekileyo okanye ulwelo lokupolisha olungathathi cala kuyacetyiswa ukuze kuthintelwe ukungcola. Ukugcinwa rhoqo, kuquka ukucoca kunye nokuhlolwa kwepleyiti yomphezulu, kunceda ukugcina ukuchaneka kwayo kunye nokwandisa ubomi bayo benkonzo.
Ukuqukumbela, ukufumana ukugqitywa okugqibeleleyo kwipleyiti yomphezulu wegranite echanekileyo kuxhomekeke ekukhetheni ngokuchanekileyo kunye nokusetyenziswa kobuchwephesha kwezinto zokupolisha kunye neearhente. Inqanaba ngalinye—ukusuka ekucoceni ukuya ekutywineni—lifuna ubuchule, ingqalelo kwiinkcukacha, kunye nolawulo oluqinileyo lweeparamitha zenkqubo. Xa yenziwe ngokuchanekileyo, isiphumo iba yiplatifomu yegranite ethe tyaba ngokugqwesileyo, ukuguda, kunye nokuqina—ukuqinisekisa ukusebenza okuthembekileyo kokulinganisa ngokuchanekileyo kunye nezicelo zokwenza ezikumgangatho ophezulu.
