Example Embodiment

[0041] Example 1

[0042] Formula: 45 parts of bentonite, 15 parts of attapulgite, 10 parts of bamboo charcoal powder, 5 parts of refined iron powder, 0.03 parts of calcium chloride and 0.03 parts of calcium propionate.

[0043] The preparation method includes the following steps:

[0044] The bentonite and attapulgite raw ore are crushed and screened by 50 meshes. They are transported to the slurrying equipment by wind power. After stirring for 3 hours, they are added to the hydraulic suspender, and the high-quality bentonite emulsion is screened through the overflow suspension and enters the filter press equipment. The rods are formed and cut into pieces with a microtome, and then fired at a low temperature (250°C) for 1 hour, and then ground into powder for later use. The prepared bentonite and attapulgite mineral powder, bamboo charcoal powder, refined iron powder, calcium chloride and calcium propionate are mixed and granulated according to the above-mentioned ratio, dried and ...

Example Embodiment

[0047] Example 2

[0048] Formula: 30 parts of bentonite, 25 parts of attapulgite, 5 parts of bamboo charcoal powder, 5 parts of refined iron powder, 3 parts of activated manganese, 5 parts of quicklime, 0.3 parts of calcium chloride and 0.5 parts of calcium propionate.

[0049] The bentonite and attapulgite raw ore are crushed, screened by 50 meshes, and transported to the slurrying equipment by wind power. After stirring for 4 hours, they are added to the hydraulic suspension, and the high-quality bentonite emulsion is screened through the overflow suspension and enters the filter press equipment. A bar is formed, cut into pieces with a microtome, and then fired at a low temperature (350°C), fired for 1 hour, and ground into powder for later use. The prepared bentonite and attapulgite mineral powder, bamboo charcoal powder, refined iron powder, calcium chloride and calcium propionate are mixed and granulated according to the above-mentioned ratio, dried and cooled under vacuum, a...

Abstract

The invention discloses a deoxidizing and drying agent which comprises the following components in parts by weight: 10-60 parts of bentonite, 10-40 parts of attapulgite, 1-20 parts of bamboo charcoal powder, 1-20 parts of fine iron powder, 1-10 parts of refined manganese dioxide, 1-10 parts of quicklime, 0.01-1 part of calcium chloride and 0.01-1 part of calcium propionate. The invention also discloses a preparation method of the deoxidizing and drying agent. The deoxidizing and drying agent can be widely used in the fields of medical health-care products, instruments and equipment, food, feed and other industries, and has the all-inclusive deoxidizing and drying effects of removing heavy metals, harmful or smelly gas, bacteria and the like; and the deoxidizing and drying agent has the advantages of cheap and accessible raw materials, simple preparation technique and long effective period, has very broad market prospects and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of deoxidizing desiccants, and relates to a deoxidizing desiccant and a preparation method thereof. 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] At present, the most common ones in China are porous silica gel desiccant. Silica gel desiccant is a kind of highly active adsorption material. The main component is silicon dioxide. It is usually reacted with sodium silicate and sulfuric acid, and undergoes a series of post-...
