AI Technical Summary

Technical Problem

In existing sea crystal preparation processes, calcium chloride and magnesium sulfate tend to adhere to each other, resulting in low solubility, slow dissolution rate, and uneven dissolution, which affects the effectiveness of applications such as aquaculture, marine organism cultivation, and seawater environment simulation experiments.

Method used

After sieving calcium chloride, it is mixed with sodium chloride to form a premix, which is then stirred evenly with magnesium chloride, magnesium sulfate and potassium chloride. The mixture is prepared in steps to obtain sea crystals. In the post-processing, the sea crystals are weighed and screened to remove unqualified products, ensuring the uniformity of components and solubility.

Benefits of technology

It improves the solubility and uniformity of sea crystals, reduces the adhesion between calcium chloride and magnesium sulfate, and enhances the dissolution effect of the finished product. It is suitable for scenarios such as aquaculture, marine organism cultivation, and seawater environment simulation experiments, reducing water ion concentration fluctuations and operation time, and lowering labor costs.

Abstract

The invention relates to a high-solubility sea crystal preparation method, which comprises: S1, mixing sodium chloride and calcium chloride according to a preset ratio to obtain a sodium chloride-calcium chloride premix, and screening calcium chloride before mixing; s2, magnesium chloride, magnesium sulfate and potassium chloride are mixed and stirred according to a preset proportion, then the sodium chloride-calcium chloride premix is added, and the sea crystal is prepared after uniform mixing. The method can pertinently reduce adhesion of magnesium sulfate and calcium chloride, reduce the situation that magnesium sulfate and calcium chloride react to generate indissolvable calcium sulfate, fundamentally solve the problems related to existing sea crystal dissolution, effectively improve the solubility of sea crystals, accelerate the dissolution speed, enable water ions to be released more uniformly, solve the problems of insufficient dissolution and easy caking, and improve the dissolution rate of the sea crystals. The finished product dissolving effect is better than that in the prior art.
