Problems solved by technology

[0004] However, the existing dehumidification rotor manufacturing materials use simple single-layer fiber paper, which has problems such as being unable to work for a long time, low strength, poor flexibility, and easy to tear during processing, so it can only be used to manufacture ordinary, low-load dehumidifiers. The special dehumidification wheel cannot meet the continuous, stable and heavy-duty working requirements of the new generation of wheel dehumidifiers.

Abstract

The invention discloses a mixed fiber composite paperboard for fabricating a dehumidification turning wheel. The mixed fiber composite paperboard is characterized by comprising an upper paper layer, a mixed fiber layer, a mixed pulp layer and a lower paper layer, wherein the upper paper layer, the mixed fiber layer, the mixed pulp layer and the lower paper layer are overlapped in sequence from top to bottom, and every two adjacent layers are connected through cement substances; and the upper paper layer and the lower paper layer are provided with internally tangent units or externally tangent units. By means of the mixed fiber composite paperboard, suppleness of dehumidification turning wheel raw materials is improved, and meanwhile molding of the dehumidification turning wheel is facilitated.

Description

technical field [0001] The invention relates to the field of manufacturing dehumidification rotors, in particular to a mixed fiber composite paperboard for manufacturing dehumidification rotors. Background technique [0002] The rotary dehumidifier belongs to an important branch of the air conditioning field. At present, the fourth-generation rotary dehumidifier is being developed. It adopts advanced solid adsorption technology and can operate continuously and stably with large-load air humidity control, especially at low temperature. Ultra-low dew point temperature can be achieved under low humidity conditions. As the core component of the rotary dehumidifier, the dehumidification wheel can be divided into a moisture absorption area and a regeneration area. After the moisture in the air is removed in the moisture absorption area, the blower sends the dried air into the room, and the wheel that absorbs the moisture Move to the regeneration area, at this time, the regenerati...
