Abstract
The invention provides a luminous pearl nucleus and a preparation method thereof as well as a method for cultivating luminous pearls. The method for preparing the luminous pearl nucleus comprises the following steps of uniformly mixing fluorescent powder with other randomly-selected components and putting the mixture into a crucible; putting the crucible into a reducing atmosphere furnace to be heated; after 5-8 hours, slowly raising the furnace temperature to 1150-1600 DEG C; pressurizing to be more than two barometric pressures and keeping a constant temperature and a constant pressure for 2-3 hours; directly utilizing a mould to press the fluorescent powder at a fused state into a luminous pearl nucleus shape; or after keeping the constant temperature and the constant pressure for 2-3 hours, naturally cooling to be condensed; and taking the crucible out of the atmosphere furnace and cooling to a room temperature, and polishing a condensed body into the luminous pearl nucleus shape. The luminous pearls cultivated by using the luminous pearl nucleus can resist corrosion of chemicals such as an acid, an alkali and the like, and can emit high-brightness light for a long time.
Description
Technical field
The present invention relates to a kind of high brightness luminous, and the luminous pearl core of high brightness of the chemicals corrosion such as resistance to bronsted lowry acids and bases bronsted lowry and use this luminous pearl core to cultivate the method for seawater Noctilucence pearl.Have more ground, the present invention relates to the method using prepared by strontium aluminate or the calcareous composite phosphor of aluminic acid and the luminous pearl core of the chemicals corrosion such as resistance to bronsted lowry acids and bases bronsted lowry and use this luminous pearl core cultivating processing Noctilucence pearl.
Background technology
As everyone knows, natural legendary luminous pearl is a kind of fluorite mineral that can be luminous, and the reason of its luminescence is caused by electronics relevant in mineral moves.When under the stimulation of the electronics in mineral in outside energy, enter upper state by low-energy state; When outside energy stimulates stopping, electronics proceeds to low-energy state by upper state again, and this process will send light.
According to this mechanism, people utilize fluorescent material as luminous pearl core to cultivate Noctilucence pearl.The such as broad-mouthed receptacle for holding liquid patent CN1053725A of people such as to be bestowed by heaven discloses and adopts in the boring of shell pearl core central part, and the method for perfusion radioactive luminescent material or fluorescent material cultivates Noctilucence pearl.But, method complex process disclosed in this patent, illumination effect is poor, and chemical constitution is unstable, is difficult to apply; And the radioactive luminescent material of perfusion is harmful to pearl shell and human body.The patent CN101243777A of the people such as Wu's alum discloses a kind of by being equipped with the RE luminous material of the long afterglow with fluorescent characteristic after paraffin melting to prepare the method for Noctilucence pearl.Pearl core wherein all adopts fluorescent material to mix with other media to prepare, and its fluorescence sent is low, and the life-span is not long, and chemical constitution is unstable.
To sum up, the Noctilucence pearl cultivated by method described in prior art has shortcoming clearly: after boring bleaching, the life-span is not long; Illumination effect is poor; Chemical constitution is unstable; And the pearl quality produced is poor.Particularly, cultivate Noctilucence pearl between its nacre and luminous pearl core, be often mingled with some naturally left dirts, these natural dirt matter can have influence on the illumination effect of Noctilucence pearl.Better, more value is had in order to make Noctilucence pearl illumination effect, usual needs carry out boring bleaching Noctilucence pearl, natural dirt left between nacre and luminous pearl core is floated totally, the illumination effect of Noctilucence pearl could be made better, more to have value.In the process of above-mentioned bleaching, usually can use some a small amount of chemical substances, such as: the eroding chemicals such as hydrogen peroxide, triethanolamine, sodium metasilicate, polyethylene glycol, disodium ethylene diamine tetraacetate.Benly be, the luminous pearl core that above-mentioned patent etc. are prepared and the Noctilucence pearl cultivated, in the process of bleaching, be unable to undergo infiltration or the stimulation of chemicals, cause luminous pearl core can slowly oxidized or corrosion, make the luminous rate variance of the Noctilucence pearl after bleaching on the contrary, the life-span is not long, significantly reduces the value of Noctilucence pearl.
Therefore, be badly in need of at present a kind ofly sending high-luminance light and the long-term durability luminous pearl core of the chemicals corrosion such as resistance to bronsted lowry acids and bases bronsted lowry, the Noctilucence pearl cultivated thus can send high-luminance light for a long time by the chemicals burn into such as resistance to bronsted lowry acids and bases bronsted lowry in bleaching process.
Summary of the invention
By numerous experiments and the effort improvement of the present inventor, cultivate the chemicals such as a large amount of resistance to bronsted lowry acids and bases bronsted lowries at present and corroded and the Noctilucence pearl sending high-luminance light for a long time.
Luminous pearl core of long-life high brightness that the object of this invention is to provide the chemicals corrosion such as a kind of high brightness and resistance to bronsted lowry acids and bases bronsted lowry and preparation method thereof.The method of operating wherein preparing described pearl core is simple, can cultivate a large amount of high-quality Noctilucence pearls sending high-luminance light for a long time.
A further object of the present invention is to provide the Noctilucence pearl using the method for above-mentioned luminous pearl core cultivation Noctilucence pearl and the method to cultivate.This Noctilucence pearl can send high-luminance light, and fluorescence decay time is long and the life-span is long; And its steady chemical structure, can the corrosion of the chemicals such as resistance to bronsted lowry acids and bases bronsted lowry in boring procedure.
Technical purpose of the present invention is achieved through the following technical solutions:
According to an aspect of the present invention, provide cultivate the Noctilucence pearl method of luminous pearl core a kind of preparation, comprise the following steps:
Fluorescent material and other optional component are mixed and inserts in crucible;
Crucible is loaded in reducing atmosphere stove and heat, made through 5-8 hour furnace temperature slowly be warming up to 1150 DEG C ~ 1600 DEG C, and be forced into more than two atmospheric pressure, constant temperature and pressure 2-3 hour; And
