Technical Field
The invention relates to a method for preparing a drying agent, in particular to a method for preparing an attapulgite drying agent for packaging.
Background
The attapulgite serving as the drying agent exists in the form of a carrier, the effect of the drying agent can be achieved only by adding calcium chloride, and the attapulgite cannot be used in the fields of electronics, machinery, rust prevention and the like because of containing chloride ions, so that the application range of the product is greatly reduced; active substances such as calcium chloride and the like are added into the existing attapulgite drying agent, so that the existing attapulgite drying agent has corrosivity, and the adsorption mode is a chemical reaction; the existing attapulgite can only be used as a carrier and cannot exert the advantage of strong adsorption.
Therefore, the preparation method of the attapulgite drying agent for packaging, which can fully exert the advantages of the attapulgite, becomes a problem to be solved urgently.
Disclosure of Invention
The technical problem to be solved by the invention is that the application range of the attapulgite is greatly reduced in the prior art; the adsorption mode is a chemical reaction; the attapulgite can only be used as a carrier and cannot exert the advantage of strong adsorption.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: the preparation method of the attapulgite desiccant for packaging comprises the following steps:
step 1: preparing attapulgite powder raw materials;
step 2: putting the selected 200-400-mesh attapulgite powder into a sugar-coating machine, and adding water to prepare spherical particles;
and step 3: putting the spherical particles into a low-temperature drying furnace for primary drying;
and 4, step 4: placing the selected attapulgite with the screened particle size of 2-5mm into a low-temperature drying furnace for secondary drying;
and 5: spraying, stirring and wetting the carefully selected 200-400-mesh attapulgite powder, and placing for the first time;
step 6: putting the placed attapulgite powder into a columnar granulator, extruding into a columnar body with the diameter of 2-5mm, and putting into a low-temperature drying furnace for primary drying;
and 7: and (4) packaging the spherical attapulgite particles dried in the step (3) and the columnar attapulgite dried in the step (6) by using a full-automatic packaging machine.
Further, the first drying and the second drying dry the water to less than 1%.
Further, the time of the first placement is half an hour.
Furthermore, the material for packaging is breathable non-woven fabric.
Further, the water absorption rate of the attapulgite powder raw material is 400%.
Compared with the prior art, the invention has the advantages that: the attapulgite powder is used as a raw material, is prepared into granular attapulgite and columnar attapulgite, and is packaged in the breathable non-woven fabric, so that the advantages of strong adsorption performance and strong drying effect of the attapulgite are fully exerted; meanwhile, the attapulgite has plasticity, and the attapulgite with smooth and uniform particles, no powder falling and easy packaging is prepared by the viscosity of the attapulgite; the physical adsorption and the regenerability of the attapulgite drying agent are fully utilized to adjust the humidity, so that the stability of the product is kept; the invention has reasonable design and is worth popularizing.
Detailed Description
