Passive compound humidity regulating particle

Abstract

Relating to the technical field of humidity regulating materials, the invention specifically discloses a passive compound humidity regulating particle. The passive compound humidity regulating particle integrates the humidity regulating advantages of porous materials, macromolecular materials and inorganic salts, and introduces a foaming agent, realizes the combination of a humidity absorbing anddesorbing medium, a humidity storage source and a humidity storage space, can be synthesized into a compound humidity regulating material with excellent humidity regulating performance, and then an anti-mildew and bacteriostatic material is added to prepare the compound humidity regulating particle that has a particle size of 0.5-3.5mm and has humidity regulating, anti-mildew and bacteriostatic functions, thereby increasing the contact area of humidity-regulating materials and air, being beneficial to fusion of humidity-regulating materials and conventional building materials, and realizing diversified application of humidity-regulating materials.

Description

technical field [0001] The invention relates to a humidity control material, which has better effects especially on the control of relative humidity in building rooms. The composite humidity-regulating particles can control the relative humidity of a relatively closed space with a certain volume within a certain range. Background technique [0002] The indoor environment of a building refers to the sum of all factors related to the building and polymorphic. The building indoor environment involving resources and energy consumption is mainly the building physical environment, which includes heat, humidity environment, light environment, acoustic environment and indoor air quality. At present, the research on indoor thermal environment has achieved fruitful results. In contrast, little research has been done on indoor wet environments. [0003] However, the building wet environment is a key factor affecting human thermal comfort, human health, storage of goods, durability o...

AI Technical Summary

Problems solved by technology

For example, the moisture absorption and dehumidification process of the building envelope not only affects the dynamic humidity balance of the indoor air, but also affects the thermal balance process of the indoor air; condensation and dew condensation on the building surface and inside will deteriorate the thermal performance of the building maintenance structure, Increasing the energy consumption of building heating and air conditioning will make the durability of the building maintenance structure worse; the flooding of the building surface will cause mold to multiply and induce various diseases in the human body

In addition, when the relative humidity of the air is lower than 40%, it is easy to generate static electricity, which will cause immeasurable harm in a special environment; low humidity can cause dry eyes, chapped skin, and induce respiratory diseases

[0004] At present, the adjustment of indoor relative humidity mainly depends on air conditioners, humidifiers or other energy-consuming humidifiers, which not only consume a lot of power, but also are not conducive to the control of greenhouse gas emissions.
