Activator for initiating crystallization of a supersaturated solution

DETAILED DESCRIPTION The present invention is defined by the appended claims with specific embodiments being shown in the attached drawings.
For the purpose of summarizing the invention, the invention relates to an improved activator for initiating crystallization of a supersaturated solution within a flexible container.
The activator comprises a flexible screen for immersing in the supersaturated solution within the flexible container.
The flexible screen defines a plurality of apertures therein.
An activation material is affixed to the screen within the plurality of apertures.
The activation material interacts with the screen to initiate crystallization of the supersaturated solution upon flexing of the flexible screen.
In one example of the invention, the screen comprises a plurality of interwoven strands having a warp and a weave.
The screen and the activation material define a plurality of contact interfaces therebetween for creating a shearing action between the screen and the activation material upon flexing of the screen.
At least one of the abrasive particles has contact interfaces with at least two of the strands of the screen preferably a warp and a weave of the screen.
Preferably, a plurality of contact interfaces define a plurality of planes for allowing non-parallel forces to be simultaneously exerted by the screen on the activation material upon flexing of the screen.
In a more specific example of the invention, the screen is of a size of not less than 40 and not greater than 50 mesh.
Preferably, an adhesive agent adheres the activation material to the screen.
A lamination is affixed to the screen for inhibiting the initiation of crystallization.
In one embodiment of the invention, the lamination includes a tape disposed on opposed sides of the screen.
The activation material comprises a plurality of abrasive particles.
In one example of the invention, the activation material comprises particles having a diameter not larger than one third the diameter of the apertures and not smaller than one fifteenth the diameter of the apertures
