Description

Dehumidification ingot

The invention relates to a dehumidification ingot, in particular to a multi-porous block structure, which can reduce the environmental protection benefit of the packaging, and can be made into a plurality of shapes that attract consumers to enhance the economic benefits.

Mold is a kind of fungus. It is widely found in nature. It is very easy to mold mold in poorly ventilated and humid environment, and has strong reproductive ability. Food, clothing and furniture are in a poorly ventilated and humid environment. Under the condition, it is easy to get wet and mildew, and the human body has adverse effects on health in this environment. Therefore, related dehumidification products are also produced in order to reduce the humidity in the environment, keep the environment in a dry condition at all times, and reduce the growth of mold.

General dehumidification products can be classified into two types. One is a condensing dehumidifier placed somewhere and operated by electricity. It is bulky and not easy to handle, usually to improve the humidity in a large space; the other is Can be placed in a small space, some chemicals, such as calcium chloride, use its characteristics of easy adsorption with water molecules in the air, common with moisture-proof bags in food packaging or moisture-proof boxes placed in the closet However, this kind of moisture-proof method is inconvenient to use because it needs to constantly replenish the chemicals that will be consumed. Some dehumidification products divide the receiving box into upper and lower two-layer accommodating spaces, and the upper accommodating space places granular chlorine. Calcium, the lower layer is the collection of dehumidified water vapor liquid, because the collected water vapor liquid contains calcium chloride and other chemicals, if accidentally dumped and contact with surrounding objects is not easy to remove, if the human body contact will cause skin red, Inflammation of swelling, pain, etc. In addition, most users generally pour liquid containing calcium chloride into the drainage system, causing serious pollution to the environment.

Therefore, recent manufacturers have developed a reusable dehumidification product, which is mainly provided with a box-shaped or bag-shaped packaging casing, and then filled with a granular absorbent material (about 2 to 3 mm in diameter) in the packaging casing. In order to absorb moisture in the air, when the moisture absorbing material absorbs moisture, the packaging shell filled with the absorbing material particles is placed in an oven or a microwave oven to heat the moisture absorbing material that has absorbed the moisture. After the reduction, the dried hygroscopic material can re-adsorb the moisture in the air for the purpose of repeated use.

However, although the dehumidification product has the effect of repeating dehumidification, the manufacturer must first make a packaging shell or a packaging bag with plastic or cloth to collect the granular absorbent material having a diameter of about 2 to 3 mm. In the packaging shell or the packaging bag, not only the manufacturing cost is increased, but also the packaging shell or the packaging bag used by the dehumidifying product is used for drying and restoring, and the product life is caused by high heat damage of the oven or the microwave oven. Seriously shortened.

The main object of the present invention is to provide a dehumidifying ingot system which refines the main porous raw material of the dehumidifying ingot and mixes the aqueous viscose, and then stereotypes and dries the dehumidified ingot to form a porous structure having a porous structure, in addition to being good. In addition to the moisture absorption effect, it can also reduce the use of packaging bags or packaging shells and improve environmental benefits.

The object and effect of the present invention are achieved by the following techniques:

A dehumidification ingot comprising a sorbent body and an aqueous binder; the sorbent fine powder obtained by refining the sorbent body is thoroughly stirred and mixed with an aqueous adhesive at a ratio of 80%: 20% to 98%: 2%. And molding or kneading to form a predetermined block shape, and forming a porous, porous dehumidification ingot after the firing and cooling steps.
