Description

Air desiccant Technical field

The invention relates to the field of air drying, in particular to an air desiccant.

Background technique

In the production and operation activities, sometimes there are considerable requirements for the dryness of the air, sometimes it is not conducive to production and operation because the air becomes relatively humid, and sometimes some raw materials are also easily affected by the reason of the high humidity Use, therefore, in some cases, it is necessary to quickly reduce the moisture in the air, which is more conducive to the production and operation activities.

Summary of the invention

The technical problem to be solved by the present invention is to provide an air desiccant with fast drying speed and good water absorption effect.

In order to solve the above technical problems, the technical solution of the present invention is: an air desiccant whose innovation lies in: consisting of the following parts by weight of raw materials: attapulgite 50-100 parts, calcium chloride 20-50 parts, bentonite 10- 20 parts, nano silica 10-15 parts, nano magnesium oxide 15-30 parts, acrylamide 15-30 parts, anhydrous calcium chloride 10-15 parts, chitosan 5-10 parts, magnesium sulfate 5-10 Parts, carboxymethyl cellulose 10-15 parts, silica gel 10-15 parts, calcium oxide 10-15 parts, talc powder 10-20 parts, calcium propionate 10-20 parts, bamboo charcoal powder 15-30 parts, potassium oxide 18 -30 servings.

The advantages of the present invention are:

1) The air desiccant of the present invention has a fast drying speed and good hygroscopic effect; the preparation process is simple and the application range is wide; the cost is low, non-toxic and harmless, and no harmful substances are produced.
