Isipikha Esingaphakathi Kudonga Isipikha Esingabonakaliyo sisipikha esifakwa ngaphakathi kudonga esiyilelwe iinkqubo zeshishini lezifilimu zasekhaya. Le yunithi ilingana ngobubanzi be-300 mm, ubunzulu be-400 mm kunye nobude obuphakamileyo be-33.5 mm, ngoko isipikha singafihlwa ngaphakathi kudonga. Umphezulu wemboze ngomqhaphu wefayibha yokudlulisela izandi zepolymer, iphepha ludonga okanye ipeyinti ye-latex, oku okuvumela izandi ukuba zidlule ngodonga. Itekhnoloji yezandi zomphezulu idala ukungqubuzeka ngokusebenzisa isakhelo esinjengekhoni yenyosi yaze isasaze izandi kubungakanani obujikeleza kwi-180 degree. Uyilo lolu lugcina indawo, lunciphisa ukumoshakala kwamandla, kwaye lushiya ingaphakathi lendlu lingenamibhoxo yezipikha ebonakalayo.
