Problems solved by technology

For salt, alkali solution and molten salt and alkali, in an open system, if left for a period of time, the crystals will climb out along the container wall, and climb outside the container mouth to form salt and alkali stains, making the concentration of the prepared solution Reduce or cause the loss of salt and alkali in molten state, and it is difficult to clean up salt and alkali stains, which not only affects the normal production of experiments and factories, but also wastes resources

Abstract

The invention discloses a container and a preparation method for preventing solutes in salt and alkali solutions and molten salts and alkalis from creeping out. On the inner wall of the container mouth, there is a non-adhesive film sintered from the edge of the container mouth down to 0.5-1.5cm from the edge of the container mouth. The non-adhesive film is polytetrafluoroethylene or polyvinylidene with a thickness of 0.05-0.075mm. Vinyl fluoride. The container for preventing the solute in the salt and alkali solution and the salt and alkali in the molten state from climbing out can effectively prevent the phenomenon of climbing salt and alkali, and does not affect the use of salt and alkali. Moreover, the preparation method is simple, the cost is low, and it is convenient for large-scale production.

Description

technical field [0001] The invention belongs to the field of energy saving and consumption reduction, in particular to a container from which the solute in the salt and alkali solution and the salt and alkali in the molten state creep out. Background technique [0002] The phenomenon that salt and alkali climb out along with the container wall is classified as "alkali climbing" phenomenon. For salt, alkali solution and molten salt and alkali, in an open system, if left for a period of time, the crystals will climb out along the container wall, and climb outside the container mouth, forming salt and alkali stains, making the concentration of the prepared solution Reduce or cause the loss of salt and alkali in the molten state, and the salt stains and alkali stains are difficult to clean up, which not only affects the normal production of experiments and factories, but also wastes resources. This method is simple and convenient, and can effectively improve the phenomenon of "...
