Problems solved by technology

The production technology of molecular sieves has become increasingly mature, but there are still some problems in the use of molecular sieves. For example, when molecular sieves are used to absorb moisture in insulating glass, often due to the long construction and operation process, the exposed molecular sieves absorb too much moisture in the air. The result is that the amount of adsorption in the insulating glass is insufficient, which affects the smooth completion of the construction and even affects the quality of the project.

Embodiment Construction

[0012] Prepare molecular sieves to control the adsorption rate, and the weight of the raw material components is as follows:

[0013] 500 mesh zeolite powder 75-80 kg,

[0014] Carboxymethyl cellulose or lignin (pore forming agent) 1-1.5 kg,

[0015] 325 mesh attapulgite powder 18-22 kg.

[0016] See figure 1 , the production method is as follows: first 75-80 kg of 500-mesh zeolite powder, 18-22 kg of 325-mesh attapulgite powder with a weight ratio of 98-99%, and 1-1.5 kg of carboxymethyl cellulose or lignin Stir and mix, spray and granulate in a granulator (fog liquid is water, using conventional granulation process), and then coat a layer of 325-mesh attapulgite powder on the surface of the molded product, the amount of which is the remainder of the attapulgite powder amount, and then dried by drying equipment at a drying temperature of 100°C for 2 hours; finally roasted by a roasting equipment at a temperature of 600°C for 2 hours.

[0017] See Attached Table 1 for the ...

Abstract

The invention discloses a production method for controlling an adsorption rate molecular sieve. The production method is characterized by comprising the following steps of: mixing 75-80 parts by weight of 500-mesh zeolite micro mist, 18-22 parts by weight of 98-99 percent 325-mesh attapulgite powder and 1-1.5 parts by weight of carboxymethyl cellulose or lignin by stirring; performing spray granulation and shaping in a granulator; coating a layer of 325-mesh attapulgite powder on the surface of a shaped product in an amount which is the same as the remaining amount of the attapulgite powder; and drying with drying equipment, and calcining with calcining equipment.

Description

technical field [0001] The invention belongs to a technology for controlling the adsorption rate of molecular sieves, in particular to a production method of molecular sieves with controlled adsorption rate. Background technique [0002] In recent years, with the rapid development of my country's economic construction, the chemical industry has sprung up, taking the lead. Molecular sieves are used as high-efficiency adsorbents and catalyst carriers, and the demand is increasing day by day. The production technology of molecular sieves has become increasingly mature, but there are still some problems in the use of molecular sieves. For example, when molecular sieves are used to absorb moisture in insulating glass, often due to the long construction and operation process, the exposed molecular sieves absorb too much moisture in the air. The result is that the amount of adsorption in the insulating glass is insufficient, which affects the smooth completion of the construction ...
