Abstract
The invention relates to a silica-gel drying agent, which is characterized by being prepared by comprising the following steps: selecting the following components in percentage by weight: 50-70% of silica-gel, 12-15% of aluminium oxide, 8-10% of iron trioxide, 5-8% of calcium chloride, 3-6% of magnesium sulphate, 8-15% of carboxymethyl cellulose, and 0.7-1.0% of essence, uniformly mixing silica-gel, aluminium oxide, iron trioxide, calcium chloride, magnesium sulphate, carboxymethyl cellulose and essence, extruding into pills by using an extruder, feeding into a dryer, drying at 120-130 DEG C, and then, obtaining the silica-gel drying agent. The silica-gel drying agent disclosed by the invention has the advantages of being rapid in adsorption speed and high in adsorption capability and is also capable of providing fragrant air and further improving air quality.
Description
Technical field
The present invention relates to the air drying agent of chemical field, relate in particular to a kind of silica-gel desiccant.
Background technology
Silica-gel desiccant main application is to prevent that article from making moist, go mouldy and corrosion etc., play and preserve food, medicine etc., in our articles for daily use, all can use silica-gel desiccant as instrument, instrument, machinery equipment etc., the scope of application of visible silica-gel desiccant is very widely, demand is also very vigorous in the international market, adds the feature such as stable chemical nature, Heat stability is good, silica-gel desiccant more and more welcomed by the people! The effect of silica gel in drier also more and more highlights, but the very large silica gel of a lot of adsorbance is difficult to absorption under low humidity, and the speed of absorption is also slow, mainly due to its specific pore structure and structure of functional groups decision.
Summary of the invention
The object of this invention is to provide the silica-gel desiccant that a kind of adsorption rate is fast, adsorption capacity is large.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of silica-gel desiccant, its feature is: select silica gel according to weight percent: 50-70%, alundum (Al2O3): 12-15%, di-iron trioxide: 8-10%, calcium chloride: 5-8%, magnesium sulfate: 3-6%, carboxymethyl cellulose: 8-15%, essence: 0.7-1.0%, then after the silica gel of choosing, alundum (Al2O3), di-iron trioxide, calcium chloride, magnesium sulfate, carboxymethyl cellulose, essence are mixed, with extruder pellet shape, and dry and get product in 120-130 DEG C of drying environment.
Principle of the present invention is: the alundum (Al2O3) that this silica-gel desiccant contains, di-iron trioxide, calcium chloride, magnesium sulfate, the alkaline-earth metal such as carboxymethyl cellulose and alkaline-earth halide absorb steam and first form the compound containing the crystallization water from environment, further hygroscopic effect can continue to absorb water from environment and form liquid mixture, now the weak hydroxyl on macro porous silica gel surface rapidly the free water in liquid mixture be combined, that is to say the combination water that can seize in salt, make easy hygroscopic salt recover rapidly water absorbing capacity, from environment, continue adsorption moisture, thereby ensure the wettability power continuously and healthily of drier and high adsorption capacity, simultaneously silica gel hole due to a lot of micropores form capillarity by water adsorption in inner surface hole, firmly pin moisture, the carboxymethyl cellulose that the present invention contains also has good absorbent drying effect, and essence can further promote air quality, the air of delicate fragrance is provided.
Advantage of the present invention is: adsorption rate is fast, adsorption capacity is large, and the air of delicate fragrance can also be provided, and further promotes air quality.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
Select silica gel according to weight percent: 55%, alundum (Al2O3): 14%, di-iron trioxide: 9%, calcium chloride: 7%, magnesium sulfate: 5%, carboxymethyl cellulose: 9.2%, essence: 0.8%, then the silica gel of choosing, alundum (Al2O3), di-iron trioxide, calcium chloride, magnesium sulfate, carboxymethyl cellulose, essence are put into agitator and mixed, be then pressed into extruder the ball shape that diameter is 0.8cm, and send in dryer, in 125 DEG C of drying environment, dry and get product.
Embodiment 2
Select silica gel according to weight percent: 70%, alundum (Al2O3): 15%, di-iron trioxide: 9%, calcium chloride: 8%, magnesium sulfate: 4%, carboxymethyl cellulose: 12%, essence: 0.9%, then the silica gel of choosing, alundum (Al2O3), di-iron trioxide, calcium chloride, magnesium sulfate, carboxymethyl cellulose, essence are put into agitator and mixed, be then pressed into extruder the ball shape that diameter is 1cm, and send in dryer, in 128 DEG C of drying environment, dry and get product.
Embodiment 3
Select silica gel according to weight percent: 60%, alundum (Al2O3): 13%, di-iron trioxide: 10%, calcium chloride: 6%, magnesium sulfate: 6%, carboxymethyl cellulose: 14%, essence: 0.9%, then the silica gel of choosing, alundum (Al2O3), di-iron trioxide, calcium chloride, magnesium sulfate, carboxymethyl cellulose, essence are put into agitator and mixed, be then pressed into extruder the ball shape that diameter is 1cm, and send in dryer, in 130 DEG C of drying environment, dry and get product.
Through the prepared silica-gel desiccant of the present invention, the alundum (Al2O3) containing, di-iron trioxide, calcium chloride, magnesium sulfate, the alkaline-earth metal such as carboxymethyl cellulose and alkaline-earth halide absorb steam and first form the compound containing the crystallization water from environment, further hygroscopic effect can continue to absorb water from environment and form liquid mixture, now the weak hydroxyl on macro porous silica gel surface rapidly the free water in liquid mixture be combined, that is to say the combination water that can seize in salt, make easy hygroscopic salt recover rapidly water absorbing capacity, from environment, continue adsorption moisture, thereby ensure the wettability power continuously and healthily of drier and high adsorption capacity, simultaneously silica gel hole due to a lot of micropores form capillarity by water adsorption in inner surface hole, firmly pin moisture, the carboxymethyl cellulose that the present invention contains also has good absorbent drying effect, and essence can further promote air quality, the air of delicate fragrance is provided.
Embodiment recited above is described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention, all should fall into protection scope of the present invention.
