Abstract
The invention discloses an improved drying agent. The improved drying agent is prepared from the following raw materials in parts by weight: 4-8 parts of polyacrylamide, 5-20 parts of bentonite, 8-16 parts of silica gel, 3-7 parts of plant starch, 7-10 parts of calcium chloride dihydrate, 3-6 parts of lime powder, 2-6 parts of anhydrous calcium chloride, 3-15 parts of bamboo charcoal powder, 5-15 parts of refined iron powder, 5-10 parts of high water-absorbent resin, 6-11 parts of refined manganese dioxide, 5-10 parts of quick lime, 2-7 parts of calcium propionate, 7-13 parts of magnesium sulfate, 4-18 parts of attapulgite and 5-11 parts of calcium sulfate. The improved drying agent disclosed by the invention can be used for improving the moisture absorption capacity, is long in valid time and high in drying speed, and is not easy to cause a water return phenomenon.
Description
technical field [0001] The invention relates to the technical field of chemicals, in particular to an improved desiccant. Background technique [0002] Desiccant is also called adsorbent, which is used in moisture-proof and mildew-proof, and plays a drying role. According to the adsorption method and reaction product, it can be divided into physical adsorption desiccant and chemical adsorption desiccant. Physical adsorption desiccants include silica gel, alumina gel, molecular sieve, activated carbon, bone charcoal, charcoal, mineral desiccant, or activated clay, etc. Its drying principle is to physically adsorb water molecules in its own structure. [0003] In the prior art, calcium chloride desiccant is made by combining anhydrous calcium chloride with matured plant starch (eg patent CN102847417A) to make a desiccant product. After a period of time, the desiccant absorbs water and overflows in liquid form. For occasions where it is inconvenient to replace the desiccant, ...
