1. Introduction of absorbent products:

High-efficiency dehumidifier special for rescue capsule is packaged in hanging bag with upper and lower layers, and water-absorbing and breathable paper imported from the United States is used. Humid air can quickly penetrate the water-absorbing and breathable paper, enter the upper polymer absorption layer, be absorbed by polymer absorbent and become moisture, and flow to the lower water storage layer. Because the water-absorbing breathable paper can control the one-way passage of water, the absorbed water will not evaporate and overflow, so the relative humidity of the air can be maintained for a long time, which can be maintained below 65% by field test, making the escape personnel feel comfortable.

Humidity treatment in the confined space of rescue capsule and refuge chamber is the most critical. This product is specially developed and designed for mine rescue and escape system. Its main component is polymer absorbent, which can quickly absorb the humid water vapor in the air, keep the relative humidity of the air in the rescue system below 65%, and make people feel comfortable.

With fast dehumidification performance, excellent humidity control effect and ultra-low heat release, this product has become the first choice for mine life-saving system.

Second, the dehumidifier product specifications:

Packaging: bag-type absorbent and breathable paper packaging, with upper and lower layers;

Weight: 400±20g (net content of effective absorbent);

Absorption capacity: 1000ml (double absorption function);

Usage of dehumidifier:

A, tearing the external package and spreading the product flat;

B, hanging the product to a place where moisture absorption is needed;

C, this product is disposable and cannot be reused. The water precipitated after moisture absorption is weakly alkaline, non-toxic and pollution-free. After use, it can be directly discarded as garbage without treatment.

Third, the principle of rescue efficient dehumidifier:

1. Our special high-efficiency dehumidifier for rescue capsule adopts water-soluble polymer absorber formula and special waterproof and breathable packaging, which can quickly absorb water vapor in the air and store it in a sealed way, and will not evaporate and overflow, thus achieving excellent dehumidification performance.

2. Because of the reticular structure of the polymer absorber itself and the special packaging method of the product, its heat absorption performance is not obvious and can be ignored in the whole absorption process.

3. The absorption process is similar to the dissolution process of solute, and the dissolution of solute includes two processes. One is that solute particles need to absorb heat when they diffuse in water, so as to lower the temperature of the solution. The second is that when solute particles and water molecules combine to form hydrated molecules or hydrated ions, heat will be released, which will increase the temperature of the solution. The water-soluble polymer absorber in this product contains a small amount of bound water, so in the process of water absorption and dehumidification, there is actually only the process of polymer diffusion into water, which is endothermic.
