Abstract
The present invention provides a manufacturing method for nano-sized powder gel of neutral aluminum oxide (Al2O3), which mainlycomprises adjusting pH to 4.0 to 9.0 by ammonia (NH3) to produce aluminum hydroxide (Al(OH)3) after dissolving aluminum-contained crystal salts, washing, filtrating, adding adequate oxidants and additives, and adapting operation conditions, to form a nano-sized powder gel solution having UV absorbent and UV sheltering property. The product is cohered on the surface of the matter to be treated by the process of manufacture. After baking and drying, good absorbent membrane is formed, having the effect on easy-cleaning, increased hardness, smooth, improved transmittance and specific chemical property, and together with other inorganic membrane, the effect of multi-layered membrane, which has specific optical characteristics, is formed.
