Production method and water use residential equipment equipment of water use residential equipment equipment

摘要

Hydrophily, surface hardness and production method and the water use residential equipment equipment of the satisfactory water use residential equipment equipment of appearance are offered. The water use residential equipment equipment, on the membrane which includes silica in the surface of the base substance, and the membrane which includes silica, Si with SiO₂ conversion 44 - 97 mass %, Li with Li₂ O conversion 0.2 - 17 mass % and Na 2.4 - 49 mass % has with the membrane which is formed with constitution with Na₂ O conversion. Production method of the water use residential equipment equipment the base substance touching to the water at least and or processing the surface which touches to vapor atmosphere, with the coating medicine which includes silica and with respect to finishing process and the finishing layer which form finishing layer, Si with SiO₂ conversion 1 - 20 mass sections, Li 0.05 - 0.3 mass sections and Na applying the aqueous solution which with Na₂ O conversion it includes in ratio of 0.5 - 1 mass sections with Li₂ O conversion the application process which forms application layer and, it possesses.
