Abstract
The invention relates to a chemical desiccant which is composed of the following components according to weight percent: 60 to 70 percent of calcium chloride, 10 to 15 percent of zeolite powder, 5 to 10 percent of Ca(H2P04)2, 2 to 6 percent of chitosan, 1.5 to 3.5 percent of cellulose ether, 2 to 4 percent of citric acid, 0.5 to 2 percent of pigment and water as the rest. A preparation method of the chemical desiccant comprises the following steps of uniformly mixing the zeolite powder and the cellulose ether first, then heating and cooling, so as to be viscous; putting prepared viscous products into a chitosan solution, uniformly mixing, and then adding the calcium chloride, the Ca(H2P04)2, the citric acid and the pigment; then filtering the substances; finally, calcining, drying and cooling filtered solid, so as to obtain the desiccant. The desiccant can absorb ammonia gas and has the advantages of aromatic odor and high absorption efficiency. The preparation method has the advantages of simplicity, convenience and low cost.
Description
Technical field
The present invention relates to chemicals field, particularly relate to a kind of chemical drier and preparation method thereof.
Background technology
Drier is the extremely strong adsorbent of a kind of adsorption capacity.Drier is utilized to remove the material of moisture in moist material.At present, conventional drier, due to the difference of application category, is divided into physical dryness agent and chemical drier.Chemical drier generates hydrate carry out drying by being combined with water, as calcium sulfate, calcium chloride etc., and calcium chloride wherein can not absorb ammonia, normally at ambient temperature mist is passed through anhydrous calcium chloride when dry ammonia, at this moment this complex compound just not easily decomposes once generation.
In prior art, use is had to add zeolite powder or Ca (H
2p0
4)
2carry out removal ammonia, but existing technical scheme complex manufacturing, production cost is high and absorption efficiency is low.
Summary of the invention
For the defect existed in prior art, the present invention proposes a kind of chemical drier and preparation method thereof, not only efficiently can remove ammonia, and makes drier have natural fragrance.The production technology of drier is easy, and production cost is low.
For achieving the above object, the present invention proposes a kind of chemical drier, is become to be grouped into: calcium chloride 60-70%, zeolite powder 10-15%, Ca (H by following weight percent
2p0
4)
25-10%, shitosan 2-6%, cellulose ether 1.5-3.5%, citric acid 2-4%, pigment 0.5-2%, surplus is water.
Also comprise spices 0.5-1%.
Described cellulose ether is the one in methylcellulose, hydroxypropyl methylcellulose, sodium carboxymethylcellulose.
A preparation method for chemical drier, comprises the following steps:
1) carry out after zeolite powder being mixed with cellulose ether heating, cool after become thick;
2) obtained thick product is put into chitosan solution, after stirring, add calcium chloride, Ca (H
2p0
4)
2, citric acid and pigment;
3) above-mentioned substance is filtered;
4) solid after filtering is carried out roasting, oven dry, cooling can obtain catalyst.
Beneficial effect:
Calcium chloride, Ca (H is included in the composition of chemical drier of the present invention
2p0
4)
2, citric acid and pigment; Make this drier not only can absorb ammonia, also make drier itself have certain aromatic odor, improve the result of use of drier, and improve absorption efficiency.This technique is prepared easy, and cost is low.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of chemical drier, is become to be grouped into by following weight percent: calcium chloride 60-70%, zeolite powder 10-15%, Ca (H
2p0
4)
25-10%, shitosan 2-6%, cellulose ether 1.5-3.5%, citric acid 2-4%, pigment 0.5-2%, surplus is water.Also comprise spices 0.5-1%.Drier can be made to absorb ammonia composition, and drier itself has certain color, after fully absorbing ammonia, the color of drier itself can change, and can remind the drier that user more renews in time.And drier itself can also distribute certain fragrance, improves environment for use.
Described cellulose ether is the one in methylcellulose, hydroxypropyl methylcellulose, sodium carboxymethylcellulose.
A preparation method for chemical drier, comprises the following steps:
1) carry out after zeolite powder being mixed with cellulose ether heating, cool after become thick;
2) obtained thick product is put into chitosan solution, after stirring, add calcium chloride, Ca (H
2p0
4)
2, citric acid and pigment;
3) above-mentioned substance is filtered;
4) solid after filtering is carried out roasting, oven dry, cooling can obtain drier.
Carry out being heated to 200-230 DEG C after zeolite powder mixes with cellulose ether in corresponding ratio by the first step, and continue 1 hour, after be cooled to room temperature and become thick.Sticky mass joins in chitosan solution by second step by a certain percentage, adds calcium chloride, Ca (H after stirring
2p0
4)
2, citric acid and pigment.3rd step, then mixture is filtered by centrifuge, sediment is retained.4th step, sediment is carried out technique routinely carry out roasting, dry finally cool, can drier be obtained.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
