preparation example Construction

[0041] In the present invention, the preparation method of the base paper preferably comprises the following steps:

[0042] (a) mixing fibers with water, beating and dispersing to obtain fiber slurry;

[0043] (b) mixing the fiber slurry with the remaining raw materials to obtain a mixed slurry;

[0044] (c) papermaking the mixed slurry to obtain a base paper.

[0045]In the present invention, the fibers are preferably mixed with water and beaten to obtain fiber slurry. The present invention has no special requirements on the mixing method, and a mixing method well known to those skilled in the art can be used, such as stirring and mixing specifically. In the present invention, a disc refiner is preferably used for beating. The present invention has no special requirements on the degree of beating of the beating pulp, as long as it can be made. As an embodiment of the present invention, the degree of beating of the fiber pulp is 40-50°SR. In the present invention, the mas...

Abstract

The invention provides a water-free humidifying device, and belongs to the technical field of air conditioner humidifying devices. The water-free humidifying device provided by the invention comprises base paper made of an organic fiber material and a moisture absorption and desorption agent loaded on the surface and inside the base paper, the paper weight of the base paper is 10-200g / m < 2 >, and the strength of the base paper is greater than or equal to 1.5 kN / m; the moisture absorption and desorption agent is polydopamine containing sulfonate groups and inorganic nanoparticles; the water-free humidifying device is in a corrugated shape or a honeycomb shape. Polydopamine containing sulfonate groups and inorganic nanoparticles are used as moisture absorption and desorption agents, polydopamine has high hygroscopicity, and the surface of polydopamine is modified with hydrophilic sulfonate groups, so that the hygroscopicity of polydopamine is further improved; meanwhile, due to the addition of the nano particles containing the pore channels, the moisture releasability of the material can be enhanced. The moisture absorbing and releasing agent is loaded on the surface and inside the base paper, cannot be blown away by wind and is safe and environment-friendly in use.

Description

technical field [0001] The invention relates to the technical field of air conditioning humidifying devices, in particular to a waterless humidifying device and its preparation method and application. Background technique [0002] With the development of the economy and the improvement of people's living standards, air conditioners have increasingly entered people's daily lives. However, when the air conditioner is used, whether it is cooling or heating, the indoor humidity will be reduced. Low indoor air humidity will not only lead to excessive loss of human body water, resulting in chapped skin and dry mouth, but also increase dust and suspended particles, which is not conducive to human health. [0003] At present, air-conditioning humidification methods include water humidification and anhydrous humidification. In the water humidification method, a circulating water tank is installed in the air conditioner, which leads to high cost of the air conditioner, and requires ...
