Problems solved by technology

[0002] At present, common desiccant adsorption materials include silica gel, activated carbon, quicklime, etc. These desiccants have defects such as short adsorption time and poor adsorption effect under normal temperature and low humidity conditions. More expensive, the quicklime desiccant expands and heats up when it meets water, and it is easy to contaminate food and other defects

Embodiment 1

[0021] Take 67 parts of clinoptilolite and pulverize into 200 mesh powder, 11 parts of activated alumina, 8 parts of microporous calcium silicate, and 7 parts of silica gel and mix them evenly. Add appropriate amount of water to reconcile (they can be kneaded in the hand without dripping water ), extruded into strips through a template with an aperture of 1.5mm, cut into strips of 1.5-2mm with a knife, rounded on a sieve with a mesh opening of less than 1.5mm, and dried until the moisture content is 10%-25%, and then put in In the microwave oven, first control the power of 500W and bake for 20 minutes, and then control the power of 900W and bake for 15 minutes. In the preparation process, it is necessary to avoid using too much power to cause the particles to heat up too quickly, causing the cations and lattice particles in the zeolite surface and pores to move violently, which may damage the structure of the zeolite and affect the adsorption performance.

Embodiment 2

[0023] Take 75 parts of clinoptilolite and pulverize into 200 mesh powder, 16 parts of activated alumina, 10 parts of microporous calcium silicate, and 8 parts of silica gel and mix them evenly. Add appropriate amount of water to mix (knead into a dough in the hand without dripping water) ).

[0024] The rest is implemented as in Example 1.

Embodiment 3

[0026] Take 80 parts of clinoptilolite and pulverize into 200 mesh powder, 20 parts of activated alumina, 13 parts of microporous calcium silicate, and 10 parts of silica gel and mix them evenly. Add appropriate amount of water to reconcile (knead into a mass in the hand without dripping water) ).

[0027] The rest is implemented as in Example 1.

Abstract

The invention discloses a composite type zeolitic drying agent and preparing method, which comprises the following steps: allocating 67-89 wt slope zeolite, 11-26 wt activated alumina, 8-15 wt micro void calcium silicate and 7-12 wt silica gel; grinding the zeolite to 200 order powder; mixing with the activated alumina, micro void calcium silicate and the silica gel; blending with proper water; preparing to small ball body with grain diameter at 1.5-2mm; drying or air-drying with water content at 10%-25%; roasting with microwave oven; getting the product. This invention possesses strong moisture absorption ability, which can be used to food, tea, medicine and so on aspects.

Description

Technical field: [0001] The invention relates to a desiccant, in particular to a desiccant used in food, tea, grain and oil products, medicine, leather, precision instruments, books and archives, and a preparation method thereof. Background technique: [0002] At present, common desiccant adsorption materials include silica gel, activated carbon, quicklime, etc., these desiccants have short adsorption time, poor adsorption effect under normal temperature and low humidity conditions, and silica gel and activated carbon desiccants still have the price More expensive, quicklime desiccant swells and heats when exposed to water, which can easily contaminate food and other defects. Summary of the invention: [0003] The technical problem to be solved by the present invention is to provide a desiccant, which not only has a long adsorption time, but also has a very good adsorption effect even under normal temperature and low humidity conditions. Compared with desiccants such as silica g...
