Abstract
The invention discloses a preparation method of a chemical drying agent. The preparation method of the chemical drying agent comprises the following steps: (1) selecting raw materials comprising 60 to 70 percent of calcium chloride, 10 to 15 percent of zeolite powder, 2 to 6 percent of chitosan, 1.5 to 3.5 percent of hydroxypropyl methyl cellulose, 2 to 4 percent of citric acid, 0.5 to 2 percent of pigment and the balance of water; (2) mixing the zeolite powder and the hydroxypropyl methyl cellulose uniformly, heating at the temperature of 220 to 240 DEG C for 40 to 70 minutes, and naturally cooling to room temperature to be viscous; (3) putting the prepared viscous product into a chitosan solution, stirring uniformly, adding the calcium chloride, the citric acid and the pigment, and filtering; (4) baking, drying and cooling the filtered solid to obtain the drying agent. The preparation method has the advantages that the production process is adjusted reasonably, so that the production process is simple and the production cost is greatly reduced.
Description
Technical field
The invention belongs to chemicals field, and in particular to a kind of preparation method of chemical drier.
Background technology
Drier is a kind of extremely strong adsorbent of adsorption capacity.The material of moisture in moist material is removed using drier.At present, conventional drier is divided into physical dryness agent and chemical drier due to the difference of application category.Chemical drier is dried by being combined generation hydrate with water, such as calcium sulfate, calcium chloride, and calcium chloride therein can not absorb ammonia, it is typically at ambient temperature mixed gas to be passed through into anhydrous calcium chloride when dry ammonia, at this moment this complex compound is not easily decomposed once generating.
Existing technical scheme complex manufacturing, production cost is high and absorption efficiency is low.
The content of the invention
Present invention aims to the deficiencies in the prior art, now provide a kind of simple production process, the preparation method of the chemical drier of low production cost.
For achieving the above object, the technical scheme is that：A kind of preparation method of chemical drier, its innovative point is：Comprise the steps：
（1）The selection of raw material：Calcium chloride 60-70%, zeolite powder 10-15%, shitosan 2-6%, hydroxypropyl methyl cellulose 1.5-3.5%, citric acid 2-4%, pigment 0.5-2%, balance of water；
（2）Heated after zeolite powder is well mixed with hydroxypropyl methyl cellulose, the temperature is 220-240 DEG C, the heat time is 40-70 minutes, is then naturally cooled to after room temperature into thick；
（3）Obtained thick product is put into chitosan solution, calcium chloride, citric acid and pigment is stirring evenly and then adding into, is then filtered；
（4）By the solid after filtration carry out roasting, drying, cooling drier is obtained.
Beneficial effects of the present invention are as follows：The present invention passes through Reasonable adjustment production technology so that simple production process, production cost is greatly reduced.
