Abstract
The invention discloses a method for bleaching pearls with sodium percarbonate and a bleaching device, and belongs to the field of ornament artware. The method comprises the following steps: dissolving sodium percarbonate solid powder in clean water to obtain a sodium percarbonate solution; putting the sodium percarbonate solution and the punched pearl grains into a bleaching tank in the bleachingdevice, and controlling the temperature in the bleaching tank to be 0-8 DEG C; sealing the bleaching tank, and controlling the pressure in the bleaching tank to be 0.2-10MPa; after the pearl grains are bleached for 2-8 days, taking out the pearls, continuously soaking the pearls with clean water for 3-5 times, and airing the pearls once a day to obtain bleached pearls. The method is used in combination with the bleaching device, the bleaching effect of hydrogen peroxide is achieved, a pearl layer can be kept stable and not damaged by a bleaching agent, meanwhile, under a certain temperature condition, the decomposition speed and bleaching speed of the bleaching agent sodium percarbonate can be controlled through a pressure control method, the sodium percarbonate dissolved in water is keptstable, the bleaching effect of the nacreous layer is improved, and bleaching is facilitated.
