Problems solved by technology

The control of the absorption and release of water vapor is mainly realized by increasing the specific surface area. At present, people directly put powdered diatomite in the room to adjust the humidity of the air, but because it is only tiled, diatomite and The area of ​​air contact is limited, therefore, the effect of regulating air humidity is not ideal

Embodiment Construction

[0006] Take high-quality diatomaceous earth (SiO 2 content greater than 85%), the best ratio of salt sintering agent, soda ash cosolvent is 39:4.2:1, the diatomite is crushed first, and baked to make the moisture content reach 8%, which guarantees the diatomite The moisture absorption and desorption rate is controlled at 8%, and the floating range is less than 1%. Then salt sintering aid and soda ash auxiliary solvent are added, the three are fully mixed, and the temperature is 900 ° C. Write and roast for 40 minutes, sintered into blocks, and finally broken into Irregular particles with a particle size of 3 cm.

[0007] The preparation process of the invention is simple, and the adjustment effect on air humidity is good.

Abstract

The invention provides a diatomite air humidity regulator. A preparation method of the diatomite air humidity regulator relates to the field of chemical product. The main preparation material is diatomite, which has unique porous structure and strong absorption affinity. During the preparation process, salt sintering aid and soda ash cosolvent are added into the diatomite, and the mixture is sintered into blocks; then the sintered blocks are crushed into irregular granular shape and prepared into a regulator capable of regulating air humidity effectively. The sintered blocks still keep the characteristic of strong absorption affinity of the diatomite and have increased contact area with air, so as to absorb vapor in air to the largest extend and reduce humidity of environment surrounding people. When the air is dry, the air humidity regulator can automatically release moisture therein, thereby finally realizing application effects of adjusting humidity balance of air surrounding human body, adjusting breathing circulation and improving sleep environment obviously.

Description

technical field [0001] The invention relates to a diatomite air humidity conditioner, and relates to the technical field of chemical products. Background technique [0002] Diatomite is a non-metallic mineral resource with a wide range of uses. It is in powder form and has a large porosity. Its internal porosity is as high as 90%-92%. It has strong water absorption and large specific surface area. Its chemical composition SiO 2 Mainly, with a small amount of Al 2 o 3 , Fe 2 o 3 , CaO, MgO, K 2 O and organic matter, etc., among which SiO 2 The content of SiO is an important parameter to evaluate the quality of diatomite, SiO 2 The higher the content, the better its quality. When water vapor in the air contacts the surface of diatomite, the vapor molecules will adhere to the surface of diatomite material in the form of monomolecular adsorption layer, multimolecular adsorption layer or capillary condensation. The control of the absorption and release of water vapor is ...
