The present invention relates specifically to a composition for controlling ambient humidity.
“Humidity” is an important factor that affects product packaging and storage life in all walks of life. Each product requires a reasonable humidity range to store. For example, the humidity to store cigar products is about 69%, the ambient humidity below the numerical value will make the internal moisture of the cigar products too low and then accelerate the ageing of the cigar products, and the ambient humidity above the numerical value will cause the cigar products rot and then damage the taste of the cigar products. The humidity to store some seeds is about 65%-75%, the ambient humidity below the numerical value will cause the seeds to dry out and to be moth-eaten, and the ambient humidity above the numerical value will cause the seeds to become moldy and then lose their vitality. The humidity to store frozen meat food is within 65%-75%, the ambient humidity below the numerical value will cause the frozen meat food to dry up, and the ambient humidity above the numerical value will make food sticky and slip, promote bacterial growth and accelerate food spoilage.
In order to control the ambient humidity within 65%-75%, the common method is to use humidity control silica gel to control the ambient humidity. However, the use of humidity control silica gel is not in line with green products. During the manufacture of humidity control silica gel, a lot of wastewater will be produced. In order to protect the environment, many silicone raw material factories are closed for rectification. This has led various industries to start to comprise desiccant product, which is the least important in the original list of materials table, in the procurement list of important materials.
Therefore, there is an urgent need for an alternative to humidity control silica gel, and the alternative must be in line with the green and environment theme.
The present invention is made for solving the foregoing problems and aims to provide a composition for use in controlling ambient humidity.
The present invention provides a composition for use in controlling ambient humidity within 65%-75%, comprising: at least one of chloride salt and water, wherein the chloride salt comprises at least one of NaCl, NH4Cl, KCl and MgCl2, the weight percentage of the chloride salt in the composition is 12%-29.75%.
Further, the composition for use in controlling ambient humidity can also have the following features: wherein the composition for use in controlling ambient humidity comprises one of chloride salt, the chloride salt is NaCl, the weight percentage of the chloride salt in the composition is 12%-26.80%.
Further, the composition for use in controlling ambient humidity can also have the following features: wherein the composition for use in controlling ambient humidity comprises two kinds of the chloride salt, one of the chloride salt is any one of KCl and NH4Cl and the other one of the chloride salt is NaCl, the weight percentage of the NaCl in the composition is 7%-16%, the weight percentage of the NH4Cl in the composition is 5%-13.75%, the weight percentage of the KCl in the composition is 2%-10.5%.
Further, the composition for use in controlling ambient humidity can also have the following features: wherein the weight percentage of the NaCl in the composition is 11%-15%, the weight percentage of the NH4Cl in the composition is 8%-12%, the weight percentage of the KCl in the composition is 3%-8%.
Further, the composition for use in controlling ambient humidity can also have the following features: wherein the weight percentage of the NaCl in the composition is 14%-14.8%, the weight percentage of the NH4Cl in the composition is 10%-11.4%, the weight percentage of the KCl in the composition is 5%-7.4%.
Further, the composition for use in controlling ambient humidity can also have the following features: wherein the composition for use in controlling ambient humidity comprises two kinds of the chloride salt, one of the chloride salt is KCl and the other one of the chloride salt is MgCl2, the weight percentage of the MgCl2 in the composition is 6%-17%, the weight percentage of the KCl in the composition is 3%-15%, the total weight percentage of the chloride salt in the composition is 12%-29.75%.
The composition for use in controlling ambient humidity according to the present invention comprises: at least one of chloride salt and water, wherein the chloride salt comprises at least one of NaCl, NH4Cl, KCl and MgCl2, the weight percentage of the chloride salt in the composition is 12%-29.75%. Therefore, the composition for use in controlling ambient humidity of the present invention can control the ambient humidity within 65%-75%, does not need to pre-adjust the objective space, has large capacity of moisture absorption and desorption and can quickly achieve the desired humidity in the objective environment.
Moreover, since the composition for use in controlling ambient humidity of the present invention comprises only chloride salt in common, the composition manufactured by using the chloride salt is not only cheap, but also safe for human body when manufacturing, environment and the objects to be preserved. In addition, the composition is not only friendly to the natural environment in the manufacturing process, but also friendly to the natural environment after being discarded.
The composition for use in controlling ambient humidity within 65%-75% comprises NaCl and water, the weight percentage of the NaCl in the composition is 12%-26.80%.
The purity of the NaCl is not less than 99.9%. The water is deionized water.
The composition for use in controlling ambient humidity within 65%-75% comprises KCl, NaCl and water. The weight percentage of the NaCl in the composition is 7%-16%, the weight percentage of the KCl in the composition is 2%-10.5%.
The purity of the NaCl and the KCl are all food grade purity (the purity is not less than 99.9%). The water is deionized water.
When the weight percentage of the NaCl and the KCl is greater than the percentage range, crystallization is easy to occur in the composition which requires high temperature to dissolve, resulting in high loss and making the weight of the composition being unstable. When the weight percentage of the NaCl and the KCl is lower than the percentage range, it takes much longer time to manufacture the composition for use in controlling ambient humidity and the humidity control capability will decrease.
