NANO-SIZED ZINC OXIDE PARTICLE AND WATER DISTRIBUTOR THEREOF

摘要

PURPOSE: Provided is a nano-sized zinc oxide particle which reacts to the mixture of alkaline silicate compound and acidic solution to let the particle deposited on surface so that it contributes to produce a water distributor with stable distribution state. CONSTITUTION: The nano-sized zinc oxide particle is produced by comprising the steps of: (i) mixing distilled water with zinc compound as precursor to produce mixture, in which zinc compound consists of zinc sulfides, zinc carbonates, zinc hydroxides, metal zinc or other zinc compounds; (ii) on a basis of the weight of the precursor, adding 3-90wt% of soluble additive to the mixture; and (iii) drying the mixture, sintering out and then crushing the mixture.
