Embodiment 1

[0023] In the first step, the attapulgite clay is ultra-micronized and purified:

[0024] Use a target plate type liquid flow pulverizer to pulverize the attapulgite clay and depolymerize into particles with a particle size of ≤3 microns;

[0025] Then adjust the slurry concentration to 15-20wt%, put it into a screw-drive centrifuge for centrifugal purification, set the centrifugal speed to 1500-2500r / min, and obtain attapulgite with a purity greater than 90%.

[0026] The second step: the attapulgite is activated by the "acid-thermal-mechanical force" combined activation process:

[0027] (1) Acid activation, configure a sulfuric acid or hydrochloric acid solution with an acid concentration of 8%-12% by weight percentage, and a solid:liquid ratio of 1:3-1:4 by weight. The ultramicronized and purified Add the attapulgite to the prepared acid solution, fully stir for 2-4 hours, then age for 12-24 hours, then wash with distilled water to pH 7.0, and dry for later use;

[0028] (2) Therma...

Abstract

The invention discloses a preparing technology for an environment-friendly attapulgite adsorbing / drying agent. The preparing technology comprises the following steps that firstly, attapulgite clay is smashed and purified to obtain attapulgite; secondly, the attapulgite is subjected to acid, heat and mechanical force activation treatment; thirdly, the activated attapulgite and auxiliary materials are mixed, granulated and formed, and the environment-friendly attapulgite adsorbing / drying agent is obtained. Raw materials adopted in the adsorbing / drying agent are natural, environment-friendly and ecological materials, the clean and environment-friendly production process is adopted, and thus the environment-friendly attapulgite adsorbing / drying agent has the advantages of being nontoxic, odorless, free of contact corrosion and environment pollution, free of damage to the human body (no harm is caused when people mistakenly eat the adsorbing / drying agent), healthy, and environmentally friendly. The adsorbing / drying agent can be widely applied to various fields such as food, medicine, large containing packaging, instrument equipment static and dynamic dehumidification, temperature-sensitive product temperature control and humidity-control packaging, warehouse dehumidification and cooling, culture farms and historic preservation.

Description

technical field [0001] The invention belongs to the field of adsorption / drying, and in particular relates to a preparation process of an environmentally friendly attapulgite adsorption / drying agent. Background technique [0002] Attapulgite has a layer, chain, fibrous crystal structure and a microscopic structure of nano-scale pore channels, endowing the material with many excellent properties such as adsorption, mass transfer, slow release, rheology, and ion exchange. Natural attapulgite has a high content of impurities, and the presence of impurities weakens the original properties of attapulgite, such as affecting its adsorption, colloid, and decolorization properties. There are certain limitations in use, and good results cannot be achieved. In order to improve the quality of attapulgite and meet the requirements, it needs to be activated and other processes before use, mainly including: heat activation, acid activation and organic modification. The traditional technolo...
