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 vessel for preventing solute and molten state salt and alkali in salt and alkali solutions from climbing out and a preparation method thereof. According to the vessel, a layer of non-adhesive membrane is sintered at the position, 0.5-1.5cm down below the edge of the vessel mouth, on the inner wall of the vessel mouth, and the non-adhesive membrane is teflon or polyvinylidene fluoride with thickness of 0.05-0.075mm. The vessel can effectively prevent salt and alkali from climbing out without affecting the use of the salt and alkali. The preparation method is simple, has low cost and 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 "...
