Abstract
A humidity control method and apparatus that can be utilized to provide humidity control within an enclosed assembly such as a disc drive. The apparatus includes a container that is at least partially formed of a material through which water vapor can freely move. The apparatus also includes a humidity-controlling mixture that comprises at least one salt and a superabsorbent polymer. The humidity-controlling mixture is enclosed within the container.
Claims18
A method for maintaining a relatively constant humidity in an enclosure, the method comprising:
- preparing a saturated aqueous solution of at least one salt;
- introducing excess solid of the same at least one salt in intimate contact with the saturated aqueous solution;
- and
- adding a super-absorbent polymer to contain both the saturated aqueous solution and the excess solid and to adsorb a puddle that may be formed when the saturated aqueous solution and the excess solid absorb water,
- wherein the saturated aqueous solution, the excess solid and the super-absorbent polymer are included in the enclosure.
A humidity control system comprising:
- an enclosure;
- and
- means, utilizing a multi-phase mixture and an additive that adsorbs excess liquid present in the multi-phase mixture, within the enclosure for maintaining a relatively constant humidity within the enclosure.
A humidity control system comprising:
- a humidity-controlling component within an enclosure, the humidity-controlling component comprising a saturated aqueous solution of at least one salt in intimate contact with excess solid of the same at least one salt, the intimate mixture of the saturated aqueous solution of the at least one salt and the excess solid of the same at least one salt being contained within a super-absorbent polymer matrix.
