Clay drying adsorbent

Abstract

The invention relates to a clay drying adsorbent and belongs to the field of drying agents. The clay drying adsorbent comprises a drying agent and an adsorbent, wherein the drying agent is an attapulgite clay drying agent and prepared by the steps of mixing additives with attapulgite clay which is main raw material in proportion and pelletizing and calcination, and the additives include 20-30 percent by weight of molecular sieves and 10-20 percent by weight of chlorides, and the addition of attapulgite clay is 60-80 percent by weight; the adsorbent is a drying agent which is a solid substance with a porous structure; the mixing proportion of the drying agent and the adsorbent is 1:1-1:3, and the mixed drying agent and adsorbent are placed in a container. The clay drying adsorbent disclosed by the invention has purifying and drying functions and can bring more extensive purposes by having two different functions. According to the invention, very good environment friendliness is achieved; selected materials are environmental-friendly and innoxious; and a product generated after the clay drying adsorbent absorbs water is very easy to decompose in nature.

Description

technical field [0001] The invention relates to a clay drying adsorbent, which belongs to the field of desiccants. Background technique [0002] Desiccant is the most commonly used material for industrial and civilian moisture-proof packaging. The existing desiccant products include silica gel desiccant: the main component is silica, which is purified and processed from natural minerals into granular or beaded. Live ore desiccant: The appearance is gray balls, and calcium chloride is added to the clay to improve the hygroscopicity. It is most suitable for moisture absorption in an environment below 50°C. When the temperature is higher than 50 0C, the degree of "water release" of clay is greater than the degree of "water absorption". Molecular sieve desiccant: It is a synthetic desiccant product with strong adsorption to water molecules. The pore size of the molecular sieve can be controlled by different processing techniques. In addition to adsorbing water vapor, it can al...

Problems solved by technology

But low moisture absorption, poor environmental protection (non-degradable)

Montmorillonite desiccant: also known as bentonite, bentonite rock, heated, dried and crushed clay, the main features are non-toxic and degradable, but the moisture absorption performance is lower than that of silica gel desiccant

Fiber desiccant: Hengyuan fiber desiccant is made of pure natural plant fiber through a special process. Although the product is safe, the processing is complicated and the cost is high.
