Problems solved by technology

[0002] Desiccants are widely used in chemical, medical, industrial and other fields. At present, common desiccants have a high degree of moisture absorption, and the molecules are relatively heavy after being saturated with water. It is easy to damage the desiccant components for a long time, reduce the moisture absorption, and thus affect the service life of the desiccant.
And because the chemical components contained in some desiccants will cause certain damage to the body, it needs to be improved to avoid this damage as much as possible.

Embodiment Construction

[0010] A kind of general-purpose dehumidification desiccant provided by the present invention comprises silicon dioxide, diatomite, basalt powder, carbon powder, magnesium chloride, sodium tripolysilicate, water, and the mass fraction of each component is: silicon dioxide 30- 45 parts, diatomite 15-19 parts, basalt powder 16-21 parts, carbon powder 10-14 parts, magnesium chloride 6-9 parts, sodium tripolysilicate 5-6 parts, water 50-60 parts.

[0011] As a preference, the general dehumidification desiccant is characterized in that: the mass parts of the components of the general desiccant desiccant are: 30 parts of silicon dioxide, 15 parts of diatomaceous earth, 16 parts of basalt powder, 10 parts of carbon powder parts, 6 parts of magnesium chloride, 5 parts of sodium tripolysilicate, and 50 parts of water.

[0012] Preferably, the general-purpose dehumidification desiccant is characterized in that: the use environment of the silicon dioxide is below 50°C.

[0013] As a pre...

Abstract

The invention relates to a general dehumidifying desiccant. The general dehumidifying desiccant comprises the following components in parts by mass: 30 to 45 parts of silicon dioxide, 15 to 19 parts of diatomite, 16 to 21 parts of basalt powder, 10 to 14 parts of carbon powder, 6 to 9 parts of magnesium chloride, 5 to 6 parts of sodium tripolysilicate and 50 to 60 parts of water. The desiccant provided by the invention uses purely-natural silicon dioxide as a main raw material, has an open porous structure and strong adsorptivity, and is a non-corrosive, non-toxic and pollution-free green environment-friendly product; after used, the desiccant can be treated as a general waste, does not pollute the environment, and can be naturally degraded; the desiccant can maintain stable moisture absorption performance in the environments with various temperatures; the desiccant has good moisture absorption performance; and the saturated moisture absorption content of the desiccant accounts for 50%or more of the weight of the desiccant and is 1.5 times of the saturated moisture absorption content of a traditional desiccant.

Description

technical field [0001] The invention relates to the technical field of additive preparation, in particular, the invention relates to a general dehumidifying desiccant. Background technique [0002] Desiccants are widely used in chemical, medical, industrial and other fields. At present, common desiccants have a high degree of moisture absorption, and the molecules are relatively heavy after being saturated with water. It is easy to damage the desiccant components for a long time, reduce the moisture absorption, and thus affect the service life of the desiccant. . And because the chemical components contained in some desiccants can cause certain damage to the body, it needs to be improved to avoid this damage as much as possible. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a general-purpose dehumidification desiccant with good effect. [0004] The...
