Mu chikhalidwe cha masiku ano, anthu amafunika kugwiritsa ntchito zinthu zambiri zagalasi pa moyo wawo watsiku ndi tsiku, ndipo n'zosatheka kuchotsa galasi. Galasi ndi lokhazikika, losagonjetsedwa ndi asidi amphamvu ndi alkali, ndipo ndi lolimba komanso lolimba. Ndi chimodzi mwa zinthu zopangira zofunika kwambiri pazida zofunika kwambiri. Mukufuna kudziwa zambiri za momwe galasi limapukutidwira komanso momwe lingapukutidwire? Tiyeni tikambirane limodzi!
Kodi njira zopukutira magalasi ndi ziti?
Njira 1: Kupukuta Moto
Kugwiritsa ntchito lawi kufewetsa pamwamba pa galasi ndi mphamvu ya moto pa galasi kungathe kuthetsa tinthu tating'onoting'ono pamwamba pa zinthu zagalasi, koma kusalala kwa pamwamba pa galasi pambuyo pokonza kudzachepa. Kawirikawiri, pakamwa pa galasi lopanda kanthu pamakhala kolimba mutadula, ndipo njira iyi ingagwiritsidwe ntchito popukuta.
Galasi logwiritsidwa ntchito: galasi la soda laimu, galasi la silika lothamanga kwambiri.
Njira 2: Kupukuta Kupukuta Ufa
Kukangana kwachangu kwa ufa wopukuta pamwamba pa galasi kumagwiritsidwa ntchito kuchotsa mikwingwirima, zomwe zingathandize kwambiri kufalitsa kuwala ndi mphamvu ya refraction ya galasi. Musanapukute, gawo lopukutidwa liyenera kupakidwa mchenga ndi lamba wokwawa, ndipo gawo loyera liyenera kupukutidwa ndi disc ya 400-mesh emery abrasive. Pali zida zambiri ndi zipangizo zomwe zimagwiritsidwa ntchito pa njira iyi yopukutira, koma zotsatira zabwino kwambiri ndi cerium oxide ya ubweya.
Galasi logwiritsidwa ntchito: zinthu zambiri zagalasi.
Njira 3: Kupukuta Asidi
Pamwamba pa galasi pamafunika kuponderezedwa ndi asidi pa galasi. Musanapondereze, pamwamba pa galasi payeneranso kuponderezedwa ndi malamba okhwima, chifukwa kupondereza asidi kungachepetse makulidwe a galasi kwambiri, koma sikungathe kuchotsa mizere yonse ya galasi.
Galasi logwiritsidwa ntchito: galasi lililonse (koma zotsatira zake pambuyo popukuta zimatsimikiziridwa ndi galasi lokha).
Masitepe opukutira magalasi
1. Kuyeretsa ndi kukonza pamwamba pa galasi musanapukutire galasi
(1) Choyamba zungulirani m'mphepete mwa galasi kuti mukonze ndi tepi kuti mupewe kuipitsa malo ozungulira galasi likapukutidwa.
(2) Tsukani mosamala pamwamba pa galasi ndi sandpaper yopukuta magalasi, ndipo pasakhale fumbi, mchenga, ndi zina zotero.
(3) Galasi lisanapukutidwe, gwiritsani ntchito chizindikiro kuti muzungulire gawo lomwe likuyenera kupukutidwa ndi kukonzedwa kumbuyo kwa galasi kuti lisaterereke ndikupangitsa kuti malo opukutidwa akhale akulu kwambiri.
2. Gwiritsani ntchito galasi la P120#, P240#, P400#, P600#pepala losanjikiza la diamondikutsuka mikwingwirima yagalasi
(1) Dziwani kuti chitsanzo cha pepala losanjikiza pano ndi chosiyana ndi cha pepala losanjikiza loponyedwa ndi manja tsiku ndi tsiku, ndipo sichingasakanizidwe ndi pepala losanjikiza la tsiku ndi tsiku.
(2) Thirani pang'ono pa yankho la pulasitiki ngati pakufunika, sakanizani ndi madzi pa chiŵerengero cha 1:1, osapitirira 1:5, ndipo imagwiritsidwa ntchito makamaka popukuta pepala.
(3) Onetsetsani kuti madzi opukutira ndi okwanira pamalo opukutira, ndipo pepala losanjikiza silingathe kupukutidwa mwachindunji pamwamba pa galasi nthawi iliyonse.
①Kukanda kwambiri: choyamba gwiritsani ntchito pepala la sandpaper la P120# pogaya koyamba, kenako gwiritsani ntchito P240# kuti mulisongoletse, ndipo pomaliza gwiritsani ntchito pepala la sandpaper la P600# kuti mulisongoletsenso kuti pamwamba pake pakwaniritse zofunikira pakupukuta. Muthanso kuchotsa chinthuchi ndikupita mwachindunji ku gawo lachitatu.
②Kukanda pang'ono: Gwiritsani ntchito P400#Mapepala a manja a diamondi a galasi, kenako gwiritsani ntchito pepala la sandpaper la P600# kuti mulipukutenso kuti pamwamba pake pakwaniritse zofunikira pakupukutetsa. Muthanso kuchotsa chinthuchi ndikupita mwachindunji ku gawo lachitatu.
3. Sinthani ndi kuwonjezera yankho la polishing stock ndikugwiritsa ntchito gudumu lapadera lopukuta kuti mupukute ndikubwezeretsa kuwonekera bwino kwa galasi.
(1) Pukutani galasi ndikuwona momwe pepala lopukutira limagayidwira, ikani yankho lopukuta ndikugwiritsa ntchito gudumu lapadera lopukuta (ndi mphamvu yoyenera, thireyi ya makina opukuta ndi pamwamba pa galasi ziyenera kukhala zathyathyathya). Ngati palibe makina opukuta, akhoza kupukutidwa ndi pepala lopukuta lamanja. Samalani kuti musayende mofulumira kwambiri panthawiyi, ndipo mupukutire bwino kuti muwonetsetse kuti zotsatira zake zikugwira ntchito.
(2) Ngati kuwala sikuli bwino, bwerezani njira zomwe zili pamwambapa
Zinthu Zofunika Kusamala: Ngakhale kuti mikwingwirima yapamwamba yokhala ndi kuya kwa ma micron opitilira 100 ingachotsedwe popukuta, idzakhudza magwiridwe antchito achitetezo a galasi mutapukuta. Makamaka, mikwingwirima yokhala ndi kuya kwa ma micron opitilira 100 pagalasi lakutsogolo la magalimoto si yoyenera kupukuta.
Chidule chachidule ndi ichi: mchenga woyamba wonyowa wokhala ndichipika chodulira diamondikuchotsa pang'onopang'ono zizindikiro, kenako gwiritsani ntchito mapepala opukuta ndi madzi opukuta kuti mupukute komanso muwoneke bwino.
