Masiku ano, galasi lamagulu awiri ndilofala kwambiri.Sichida chokha chamadzi akumwa, komanso chingagwiritsidwe ntchito ngati ntchito yamanja.Nanga luso lake ndi lotani?Pali mitundu iwiri ikuluikulu: sandblasting ndi frosting.
1. Njira yophulitsira mchenga:
Njirayi ndiyofala kwambiri.Amagwiritsa ntchito zidutswa za mchenga zomwe zimawomberedwa ndi mfuti yopopera pa liwiro lalikulu kuti igunde pagalasi pamwamba pa galasi lawiri-wosanjikiza kuti apange malo abwino osagwirizana, kuti akwaniritse zotsatira za kuwala kobalalitsa ndikupangitsa kuwala kupyola kumverera kwamdima.Kumveka kwapamwamba kwa ndondomeko ya mchenga kumakhala kovuta, ndipo chifukwa chakuti pamwamba pawonongeka, botolo lagalasi lomwe limawoneka lowala poyambirira limawoneka ngati galasi loyera muzithunzithunzi.The ndondomeko zovuta ndi avareji.
2. Kuzizira:
Kuzizira kwa galasi lawiri wosanjikiza kumatanthauza kumizidwa mugalasi mumadzi okonzeka asidi (kapena kugwiritsa ntchito phala la asidi), kugwiritsa ntchito asidi amphamvu kuti awononge pamwamba pa galasi, ndi hydrogen fluoride ammonia mu njira ya asidi yamphamvu imayambitsa galasi. pamwamba kupanga makhiristo.Choncho, ngati chisanu chikuchitika bwino, pamwamba pa galasi lachisanu lachisanu ndi chimodzi ndi losalala kwambiri, ndipo zotsatira za hazy zimachitika chifukwa cha kubalalika kwa makhiristo.
Ngati pamwamba ndi ovuta kwambiri, zikutanthauza kuti asidi wawononga kwambiri galasi, chomwe ndi chiwonetsero cha umisiri wosakhwima wa frosting master.Kapena pali mbali zina zomwe zilibebe makhiristo (omwe amadziwika kuti alibe mchenga, kapena galasi ali ndi mottling), koma luso la mbuye silimayendetsedwa bwino.Njirayi ndi yovuta mwaukadaulo.
Njirayi imawonetseredwa ndi maonekedwe a makhiristo onyezimira pamwamba pa galasi lawiri-wosanjikiza, lomwe limapangidwa pansi pavuto lalikulu.
Ndikukhulupirira kuti nonse mumamvetsetsa njira ziwirizi, ndipo mutha kusankha malinga ndi zosowa zenizeni.
