Pankhani yopanga zinthu zolondola kwambiri, kupeta ndi kupukuta kwa mbale za granite kumachita gawo lalikulu pakuzindikira kusalala kwa pamwamba, gloss, ndi kulondola kwathunthu. Ngakhale miyala ya granite ndi imodzi mwazinthu zachilengedwe zolimba komanso zokhazikika, kukwaniritsa kulondola kwamlingo wa micrometer kumatengera kusankha mosamala komanso kugwiritsa ntchito bwino zakumwa zopukutira ndi zopukutira.
Panthawi yopera, zakumwazi ndi zothandizira sizimangokhudza kuchotsedwa kwa zinthu komanso zimakhudzanso kutha kwa pamwamba ndi kukhazikika kwa nthawi yaitali kwa nsanja ya granite. Kusankha mtundu woyenera ndi kapangidwe kake ndikofunikira kuti tipeze zotsatira zabwino komanso kukulitsa moyo wa gawo lolondola la granite.
M'ntchito zaukatswiri, zakumwa ndi zinthu zomwe zimagwiritsidwa ntchito popera papulatifomu ya granite nthawi zambiri zimagawidwa m'magulu anayi: zotsukira, zomatira, zopukutira, ndi zosindikizira.
Zoyeretsa zimagwiritsidwa ntchito pochotsa zonyansa ndi zotsalira pamwamba pa granite - monga mafuta, oxide, kapena fumbi labwino - asanayambe kapena atatha. Njira zoyeretsera zodziwika bwino zimaphatikizapo zotsuka za pH zosalowerera ndale, ma acidic pang'ono, kapena zotsukira zamchere. Pogwiritsira ntchito zotsukira mankhwala, ogwira ntchito ayenera kuyang'anitsitsa nthawi ndi nthawi kuti ateteze kutsekemera kwa mankhwala kapena kusungunuka kwa granite pamwamba.
Abrasives amagwira ntchito ngati njira yofunika kwambiri yochotsera zinthu. Njere zonyezimira zimadula ndi kuyeza pamwamba pa granite kuti zithetse zolakwika zazing'ono, zokanda, ndi zosagwirizana. Zida zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu, silicon carbide, ndi mankhwala a silika apamwamba kwambiri. Kusankhidwa kwa mtundu wa abrasive, kukula kwa tinthu, ndi kuyika kwake kumadalira kuuma kwa granite ndi kulondola kwapamwamba kofunikira. Kuti amalize bwino, ma abrasives okhala ndi tinthu tating'onoting'ono tating'onoting'ono amagwiritsidwa ntchito kuti akwaniritse malo osalala mkati mwa 1-2 µm kulolerana kwa flatness.
Zopukuta zimagwiritsidwa ntchito pambuyo popera kuti ziwongolere kusalala komanso gloss. Munthawi imeneyi, cholinga sikuchotsa zinthu koma kukonzanso mawonekedwe ang'onoang'ono. Mapangidwe apamwamba otengera polyurethane, acrylic compounds, ndi chromium oxide nthawi zambiri amagwiritsidwa ntchito popanga chomaliza ngati galasi. Kuyendera koyenera pakati pa kuthamanga, liwiro, ndi mawonekedwe a wothandizira ndikofunikira kuti mukwaniritse kuwala kofanana popanda kusokoneza kulondola.
Pomaliza, zosindikizira zimagwiritsidwa ntchito ngati chotchinga choteteza kamodzi kupukuta kwatha. Granite yokha imalimbana kwambiri ndi dzimbiri komanso kutentha kwa kutentha, koma kugwiritsa ntchito chosindikizira choyenera kumathandizira kukana madzi, mafuta, ndi fumbi ndikusunga mawonekedwe a nsanja komanso kukhazikika kwa makina. Opanga akatswiri nthawi zambiri amagwiritsa ntchito zosindikizira za polima kapena sera kuti zitetezedwe kwa nthawi yayitali, makamaka m'malo okhala ndi chinyezi kapena ma labotale.
Pochita mphero ya granite ndi kupukuta, ogwira ntchito ayenera kuonetsetsa kuti kutentha ndi chinyezi kumayendetsedwa-nthawi zambiri 20 ± 1 ° C - kuteteza kutentha kwa kutentha. Kugwiritsa ntchito madzi oyeretsedwa kapena zakumwa zopukutira zopanda ndale kumalimbikitsidwanso kupewa kuyambitsa zonyansa. Kusamalira nthawi zonse, kuphatikizapo kuyeretsa ndi kuyang'ana pamwamba pa mbale, kumathandiza kusunga kulondola kwake ndikuwonjezera moyo wake wautumiki.
Pomaliza, kumaliza bwino pa mbale yolondola kwambiri ya granite kumadalira kusankha kolondola komanso kugwiritsa ntchito mwaukadaulo kwa zakumwa zopukutira ndi othandizira. Gawo lirilonse-kuyambira kuyeretsa mpaka kusindikiza-limafuna ukatswiri, kusamalitsa mwatsatanetsatane, ndikuwongolera mosamalitsa magawo azinthu. Zikachitidwa bwino, zotsatira zake zimakhala nsanja ya granite yokhala ndi kutsetsereka kwapadera, kusalala, ndi kulimba-kuonetsetsa kuti ntchito yodalirika yoyezetsa molondola ndi ntchito zopangira zapamwamba.
