Kodi Mitundu ya Madzi ndi Zopangira Zopukutira Zomwe Zimagwiritsidwa Ntchito Popukutira Granite Surface Plate?

Pankhani yopanga zinthu molondola kwambiri, kupukutira ndi kupukuta mbale za granite pamwamba pa nthaka kumathandiza kwambiri pakudziwa kusalala kwa pamwamba, kunyezimira, komanso kulondola konse. Ngakhale granite ndi imodzi mwa zipangizo zachilengedwe zovuta komanso zokhazikika, kukwaniritsa kulondola kofunikira kwa micrometer kumadalirabe kusankha mosamala ndi kugwiritsa ntchito moyenera zakumwa zopukutira ndi zinthu zopukutira.

Pa nthawi yopera, zakumwa ndi zinthuzi sizimangokhudza kuchuluka kwa zinthu zomwe zachotsedwa komanso zimakhudza kutha kwa pamwamba komanso kukhazikika kwa nsanja ya granite kwa nthawi yayitali. Chifukwa chake, kusankha mtundu woyenera ndi kapangidwe kake ndikofunikira kuti mupeze zotsatira zabwino ndikuwonjezera nthawi ya moyo wa gawo lolondola la granite.

Mu ntchito zaukadaulo, zakumwa ndi zinthu zomwe zimagwiritsidwa ntchito popera nsanja ya granite nthawi zambiri zimagawidwa m'magulu anayi ogwira ntchito: zotsukira, zopukutira, zopukutira, ndi zomatira.

Zotsukira zimagwiritsidwa ntchito makamaka kuchotsa zodetsa ndi zotsalira pamwamba pa granite—monga mafuta, okusayidi, kapena fumbi laling'ono—asanayambe kupukutidwa komanso atapukutidwa. Njira zotsukira zodziwika bwino zimaphatikizapo zotsukira za pH zosalowerera, zotsukira zokhala ndi asidi pang'ono, kapena zotsukira za alkaline. Pogwiritsa ntchito zotsukira za mankhwala, ogwiritsa ntchito ayenera kuwongolera kuchuluka kwa madzi ndi nthawi yowonekera kuti apewe kuuma kwa mankhwala kapena kufooka kwa pamwamba pa granite.

Ma abrasives amagwira ntchito ngati njira yofunika kwambiri yochotsera zinthu. Tinthu ta abrasive timadula ndikulinganiza pamwamba pa granite kuti tichotse zolakwika zazing'ono, mikwingwirima, ndi kusafanana. Zipangizo zo abrasive zomwe zimagwiritsidwa ntchito kwambiri ndi alumina, silicon carbide, ndi mankhwala a silica oyeretsedwa kwambiri. Kusankha mtundu wa abrasive, kukula kwa tinthu, ndi kuchuluka kwake kumadalira kuuma kwa granite komanso kulondola kofunikira kwa pamwamba. Pakumaliza bwino, ma abrasives okhala ndi tinthu ta sub-micron amagwiritsidwa ntchito kuti akwaniritse malo osalala kwambiri mkati mwa 1–2 µm.

Zodzoladzola zimagwiritsidwa ntchito akamaliza kupukuta kuti pamwamba pakhale posalala komanso kunyezimira. Pa gawoli, cholinga si kuchotsa zinthu koma kukonza kapangidwe kake kakang'ono. Mapangidwe apamwamba ochokera ku polyurethane, acrylic compounds, ndi chromium oxide nthawi zambiri amagwiritsidwa ntchito popanga mawonekedwe ofanana ndi galasi. Kulinganiza koyenera pakati pa kuthamanga, liwiro, ndi kapangidwe kake ndikofunikira kwambiri kuti pakhale kuwala kofanana popanda kusokoneza kulondola.

Pomaliza, zomatira zimagwiritsidwa ntchito ngati choteteza akamaliza kupukuta. Granite yokha imalimbana kwambiri ndi dzimbiri ndi kusintha kwa kutentha, koma kugwiritsa ntchito chomatira choyenera kumathandizira kuti madzi, mafuta, ndi fumbi zisawonongeke komanso kuti makina a pulatifomu azikhala olimba. Opanga akatswiri nthawi zambiri amagwiritsa ntchito zomatira zopangidwa ndi polima kapena sera kuti atsimikizire chitetezo cha nthawi yayitali, makamaka m'malo okhala ndi chinyezi chambiri kapena m'malo ochitira kafukufuku.

Pogaya ndi kupukuta granite, ogwiritsa ntchito ayenera kuonetsetsa kuti kutentha ndi chinyezi zili bwino—nthawi zambiri 20 ± 1 °C—kuti apewe kusintha kwa kutentha. Kugwiritsa ntchito madzi oyera kapena madzi opukutira osagwirizana ndi kutentha kumalimbikitsidwanso kuti mupewe kuipitsa. Kusamalira nthawi zonse, kuphatikizapo kuyeretsa ndi kuyang'ana mbale pamwamba, kumathandiza kusunga kulondola kwake ndikuwonjezera nthawi yake yogwirira ntchito.

Pomaliza, kupeza mapeto abwino pa granite pamwamba pa mbale yolondola kumadalira kusankha bwino ndi kugwiritsa ntchito bwino zinthu zopukutira ndi zinthu zina. Gawo lililonse—kuyambira kuyeretsa mpaka kutseka—limafuna ukatswiri, chisamaliro chapadera, ndi kuwongolera mosamala magawo a ntchito. Mukachita bwino, zotsatira zake zimakhala nsanja ya granite yokhala ndi kusalala kwapadera, kusalala, komanso kulimba—kutsimikizira magwiridwe antchito odalirika poyesa molondola komanso kugwiritsa ntchito zinthu zapamwamba kwambiri.
