Emkhakheni wokukhiqiza okunembe kakhulu, ukugaywa nokupholishwa kwamapuleti angaphezulu kwegwadle kudlala indima ebalulekile ekunqumeni ukucaba kwendawo, ukucwebezela, kanye nokunemba kukonke. Nakuba igwadle ingenye yezinto zemvelo eziqinile nezime kakhulu, ukuzuza ukunemba kweleveli ye-micrometer kusancike ekukhethweni okucophelela kanye nokusetshenziswa okulungile koketshezi lokupholisha nama-ejenti wokupholisha.
Phakathi nenqubo yokugaya, lezi zinto eziwuketshezi nama-ejenti azithinti nje kuphela amanani okususwa kwezinto kodwa futhi zithinta ukuphela kwendawo kanye nokuzinza kwesikhathi eside kweplatifomu yegwadle. Ngakho-ke ukukhetha uhlobo olufanele nokwakheka kubalulekile ukuze kuzuzwe imiphumela emihle nokwelula isikhathi sokuphila sengxenye ye-granite enembile.
Ezinhlelweni zokusebenza zobungcweti, uketshezi nama-ejenti asetshenziselwa ukugaya inkundla yegwadle ngokuvamile ahlukaniswa abe izigaba ezine zokusebenza: izihlanzi, iziqholo, izinto zokupholisha, nama-sealant.
Izinto zokuhlanza zisetshenziselwa ngokuyinhloko ukususa ukungcola nezinsalela endaweni yegwadle—njengamafutha, i-oxide, noma uthuli olucolekile—ngaphambi nangemuva kokugaya. Izixazululo ezijwayelekile zokuhlanza zihlanganisa izihlanzi ze-pH ezingathathi hlangothi, ama-ejenti ane-asidi emnene, noma iziwashi ezine-alkali. Uma kusetshenziswa izihlanzi zamakhemikhali, opharetha kufanele balawule ukugxilisa ingqondo nesikhathi sokuchayeka ukuze bavimbele ukushibilika kwamakhemikhali noma ukufiphala kwendawo yegwadle.
Ama-Abrasives asebenza njengendlela eyinhloko yokususa izinto. Izinhlamvu ezilimazayo zisika futhi zileveli indawo engaphezulu yegwadle ukuze kuqedwe amaphutha amancane, imihuzuko, nokungalingani. Izinto ezisetshenziswa kakhulu zokugwaza i-alumina, i-silicon carbide, nezinhlanganisela ze-silica ezihlanzekile kakhulu. Ukukhethwa kohlobo lwe-abrasive, usayizi wezinhlayiyana, nokugxilisa ingqondo kuncike ebukhuni begwadle kanye nokunemba kwendawo edingekayo. Ukuze kuqedwe kahle, ama-abrasive anosayizi bezinhlayiyana ezincane ze-micron asetshenziselwa ukuzuza izindawo eziyisicaba ngaphakathi kokubekezelelana kokucaba okungama-1–2 µm.
Ama-ejenti wokupholisha asetshenziswa ngemva kokugaya ukuze kuthuthukiswe ubushelelezi bendawo nokucwebezela. Kulesi sigaba, inhloso akukhona ukususwa kwezinto ezibonakalayo kodwa intuthuko yokuthungwa kwe-micro-surface. Ukwakhiwa okuthuthukisiwe okusekelwe ku-polyurethane, izinhlanganisela ze-acrylic, ne-chromium oxide kuvame ukusetshenziselwa ukukhiqiza isiphetho esifana nesibuko. Ibhalansi elungile phakathi kwengcindezi, isivinini, kanye nokwakheka kwe-ejenti kubalulekile ukuze kuzuzwe ukukhanya okufanayo ngaphandle kokuphazamisa ukunemba.
Ekugcineni, ama-sealants asetshenziswa njengongqimba oluvikelayo uma ukupholisha sekuqediwe. I-Granite ngokwayo imelana kakhulu nokugqwala nokuhlukahluka kwezinga lokushisa, kodwa ukusebenzisa isivalo esifanelekile kuthuthukisa ukumelana namanzi, uwoyela, nothuli kuyilapho kugcinwa ukuqina kweplathifomu yokubona nokusetshenziswa. Abakhiqizi abangochwepheshe bavame ukusebenzisa ama-polymer noma ama-wax-based sealants ukuze baqinisekise ukuvikeleka kwesikhathi eside, ikakhulukazi ezindaweni ezinomswakama ophezulu noma elabhorethri.
Lapho benza i-granite yokugaya nokupholisha, opharetha kufanele baqinisekise izinga lokushisa elilawulwayo kanye nemvelo yomswakama-imvamisa engu-20 ± 1 °C-ukuvimbela ukuwohloka kokushisa. Ukusebenzisa amanzi ahlanzekile noma uketshezi lokupholisha olungathathi hlangothi nakho kuyanconywa ukuze ugweme ukwethula ukungcola. Ukunakekelwa okuvamile, okuhlanganisa ukuhlanzwa nokuhlolwa kwe-surface plate, kusiza ukulondoloza ukunemba kwayo nokwelula impilo yayo yesevisi.
Sengiphetha, ukuzuza isiphetho esingenasici kupuleti elingaphezulu legwadle elinembayo kuncike ekukhethweni okunembile nasekusetshenzisweni okuchwepheshile koketshezi lokupholisha nama-ejenti. Isigaba ngasinye—kusukela ekuhlanzweni kuya ekubekweni uphawu—sidinga ubuchwepheshe, ukunakwa emininingwaneni, nokulawula okuqinile kwemingcele yenqubo. Uma kwenziwa kahle, umphumela uba inkundla yegwadle enobucwebe obukhethekile, ukushelela, nokuqina—ukuqinisekisa ukusebenza okuthembekile kokulinganisa okunembayo nezinhlelo zokusebenza zokukhiqiza ezisezingeni eliphezulu.
