Embodiment 1

[0030] Mix 50 kg of measured 3A molecular sieve raw powder with 20 kg of kaolin, 15 kg of attapulgite clay and 15 kg of bentonite, and transport them to the rotary automatic ball forming machine. Add 0.5 kg of water-soluble adhesive carboxymethyl cellulose Soluble in water and diluted with an appropriate amount of water, while continuously spraying the aqueous adhesive solution, the small balls gradually grow up and form a molecular sieve body with a certain particle size. Then, dissolve 0.1 kg of potassium silicate, an additional compressive strength enhancer, in 10 kg of water, and spray the prepared aqueous solution of potassium silicate onto the formed molecular sieve body to coat and reinforce it; then transfer it to a special granular Dry it in a natural energy drying car for 20-40 hours, then blow off the dust with compressed air in a powder blower and polish it; bake it in a roasting furnace at a temperature of 480-700°C for 2-6 hours. After passing the inspection, it ...

Abstract

The invention is a hollow glass desiccant and process for preparation, which belongs to desiccating agent of zeolite molecular sieve, particularly relates to a hollow glass desiccant and process for preparation, which comprises the steps as follows: 3A molecular sieve original powder 50.0-8.0.% and clay 20.0-50.0% are mixed to form main component, then water-soluble adhesive agent 0.1-5.0% (Wt%) and proper amount of water which calculate the main components by percentage by weight are added for balling and pelleting, and water solution of compression strength reinforcing agent 0.1-5.0% (Wt%) which calculate the main component by percentage by weight is sprayed on a balling billet body, then the balling billet body is covered, reinforced, dried in nature, blown, and polished and baked at 480-700 DEG C for 2-6 hours, finally the desiccant can be obtained. The desiccant components of the invention are reasonably matched, the preparation is novel, the structure of the device is simple, and energy is saved. The hollow glass desiccant which is made achieves an idea effect in some aspects of the technical indicator of special requirements for hollow glass desiccant such as compressive strength, powder dropping rate and selective adsorption for each air component and the like.

Description

technical field [0001] A hollow glass desiccant and a preparation method thereof belong to zeolite molecular sieve desiccants, in particular to a hollow glass desiccant and a preparation method thereof. Background technique [0002] Hollow glass doors and windows are used in transportation tools such as vehicles and ships and fixed buildings, which is a great initiative for human beings to save energy and protect the environment. The thermal conductivity of air is low, and the air embedded in the insulating glass makes an outstanding contribution to its thermal insulation performance, but the physical properties of the air and the small amount of moisture that enters the insulating glass interlayer change with the change of temperature, which also brings new problems to the manufacture and use of insulating glass. A lot of trouble. When the ambient temperature drops below the dew point of the moisture in the insulating glass interlayer, dew condensation or even frost will f...
