Problems solved by technology
[0004] The technical problem to be solved by the present invention: Aiming at the problem that the current non-humid desiccant desiccant is easily saturated in adsorption, has a small moisture absorption capacity, and the dehumidified desiccant has a strong hygroscopic ability, but it is easy to break and produce liquid after absorbing a large amount of water, and it is not convenient to use. The preparation method of desiccant

[0017] A preparation method of an air dehumidifier, the preparation method comprising the steps of:
[0018] (1) Take sodium alginate and add distilled water to mix according to the mass ratio of 1:5~8, stir and mix at 40~50°C for 30~40min to obtain the mixed solution, in parts by mass, take 20~30 parts of the mixed solution, 100~ 150 parts of silicon nitride powder, 3~8 parts of triammonium citrate, and 15~20 parts of amino silicone oil are mixed, placed in a ball mill, ball milled for 4~5 hours to obtain a ball mill, rotary evaporation, injection molding, and a base material;
[0019] (2) Spray calcium chloride solution with a concentration of 1mol / L on the surface of the base material at a mass ratio of 3~5:1~3, let it stand for 2~3 days, demould, and obtain the mold material, and take the mold material at a mass ratio of 1 : Add gluconolactone solution in 2~4, soak at 30~40°C for 18~24h, take out the mold material after soaking, wash with distilled water, and freeze-dry to...

The invention discloses a preparation method of an air dehumidifier and belongs to the field of environment protection. methacrylic acid grafted methylcellulose is added to a dehumidifier; damp absorption increases with enhancement of polarity of hydrophilic groups of a monomer; ion groups of high polarity containing massive high-polarity groups -SO3- form hydrogen bonds with water; the water is fixed to macromolecular chains; finally, part of the water is left in the macromolecular material; the damp-absorbing capacity of a macromolecular damp-adjusting material is significantly higher than that of non-ionic group materials, especially CaCl2-modified polymethylacrylic acid; water can be absorbed to great extent; after massive water is absorbed, breaking to generate a liquid never occurs;the air dehumidifier is convenient to use. The problem is solved herein that existing non-hygroscopic dehumidifiers have easily saturated specific surface absorption and have low damp absorbing content and high damp absorbing performance, and however, after absorbing massive water, the existing non-hygroscopic dehumidifiers easily breaks to generate liquid and are inconvenient to use.
Description
technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a preparation method of an air dehumidifier. Background technique [0002] Air dehumidifiers use solid or liquid materials with dehumidification properties to directly contact the air to achieve air dehumidification. Because it is easy to achieve isothermal dehumidification, the irreversible loss is small, and the thermodynamic perfection is high; lower-grade heat energy can be used as the driving energy; there are no large moving parts, the structure is simple, and it is easy to miniaturize; it can remove harmful dust, bacteria, etc. in the air It has been widely used for its advantages of improving air quality and improving air quality. Air humidity is an important environmental parameter that is closely related to people's life and production. Humidity is of great significance to human comfort, product production process, product quality and product shelf l...
