"Kuchuluka kwa zinthu zolimba mu guluu wopangidwa ndi madzi kumakhudza mwachindunji kapangidwe kake, nthawi youma, mphamvu yomangira ndi mphamvu yomangira ya guluu wopangidwa ndi madzi. Pakadali pano, kuchuluka kwa zinthu zolimba mu guluu wopangidwa ndi madzi womwe umagwiritsidwa ntchito pamsika nthawi zambiri ndi 50% ~ 55%. Mu guluu wopangidwa ndi mapepala, guluu wokhala ndi zinthu zolimba zambiri pansi pa njira yofanana ndi yabwino kwambiri pomangirira koyamba, kuika mwachangu, ndi kuchuluka komweko kwa guluu chifukwa cha kuchuluka kwa zinthu zothandiza, kotero zotsatira zake zimakhala zabwino. Ubwino uwu umawonekera makamaka mu kapangidwe ka guluu wopangidwa ndi automaton. Mu guluu wa PVC pansi kapena guluu wa ceramic tile, guluu wokhala ndi zinthu zolimba zambiri amakhala wodzaza chifukwa cha filimu, yomwe ndi yoyenera kwambiri pakumangirira pamwamba. Nthawi yomweyo, chinthu chokhala ndi zinthu zolimba zambiri, liwiro lopanga filimu mwachangu, nthawi yochepa yochira, ndikukweza kwambiri magwiridwe antchito omanga. Kwa zaka ziwiri zapitazi, mankhwala a motian akhala akudzipereka pakupanga machitidwe a emulsion okhala ndi zinthu zolimba zambiri. Pakadali pano, tapanga bwino mafakitale opanga mapangidwe a guluu wopangidwa ndi madzi okhala ndi zinthu zolimba za 65% ~ 70% ndi kukhuthala kwa 500 ~ 2000%.
