Problems solved by technology

The machinery for adjusting humidity mainly includes dehumidifiers, humidifiers, and constant humidity air conditioners. The advantage of this method is high efficiency, but the disadvantage is that it consumes a lot of energy to adjust humidity continuously when it is turned on 24 hours a day; non-mechanical adjustment mainly refers to the use of humidity adjustment. The moisture absorption and desorption properties of the material can independently and adaptively adjust the environmental humidity. This method does not require any mechanical equipment and energy consumption, and is an environmentally friendly control and adjustment method

Abstract

A making method of an efficient composite antibacterial humidity controlling paperboard comprises the following steps: 1, taking ammonium sulfate, magnesium chloride, PCA-Na and diatomite, and adding the taken materials into water; 2, taking carboxymethyl cellulose, and dissolving carboxymethyl cellulose in water; 3, adding chitosan lactate to a dirty solution prepared in step 1, and fully uniformly mixing; 4, adding paper to a liquid prepared in step 3, fully stirring, adding a solution prepared in step 2, and stirring in one direction; 5, fully breaking by a breaker; 6, weighing sodium polyacrylate and polyethyleneimine resins, and adding the resins while stirring; and 7, putting a product obtained in step 6 in an oven, and drying at 120DEG C for 2h to obtain a final product. Compared with paperboards made through the prior art, the efficient composite antibacterial humidity controlling paperboard has the advantages of efficient and rapid adjustment of the relative humidity of microenvironment, simple production technology and apparatus, very convenient regeneration and reuse, no generation of harmful substances in the production process, and antibacterial performance.

Description

technical field [0001] The invention relates to a method for preparing a moisture-adjusting antibacterial cardboard, which is mainly suitable for protecting cultural relics prone to bacteria. Background technique [0002] Humidity control is an important topic in human life. Relative air humidity is an important parameter to measure the indoor environment. Appropriate humidity plays a very important role in human health and industrial and agricultural production. Humidity adjustment methods include mechanical adjustment and non-mechanical adjustment. The machinery for adjusting humidity mainly includes dehumidifiers, humidifiers, and constant humidity air conditioners. The advantage of this method is high efficiency, but the disadvantage is that it consumes a lot of energy to adjust humidity continuously when it is turned on 24 hours a day; non-mechanical adjustment mainly refers to the use of humidity adjustment. The moisture absorption and desorption properties of the ma...
