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.

Embodiment 1

[0015] The upper paper layer, mixed fiber layer, mixed pulp layer and lower paper layer of the mixed fiber composite paperboard used for the manufacture of the dehumidification rotor are stacked sequentially from top to bottom, and the adjacent two layers are bonded by a mixture of polypropylene and polyethylene , wherein the mass fraction of polypropylene is 42%; the upper paper layer is provided with a number of outer cutting units for the outward bending of the upper paper layer, and the lower paper layer is provided with a number of inner cutting units for the inward bending of the lower paper layer. Bending; the mass fraction of each component of the mixed fiber layer is: 40% non-asbestos mineral fiber, 10% graphite fiber, 10% carbon fiber, 10% basalt fiber, 10% glass fiber, 5% sizing agent, 15% additive %; the mass fraction of each component of the mixed pulp layer is: wood pulp 20%, straw pulp 20%, hemp pulp 20%, reed pulp 10%, bamboo pulp 10%, sizing agent 10%, auxiliar...

Embodiment 2

[0017] The adjacent two layers of the composite paperboard are bonded by a mixture of polypropylene and polyethylene, wherein the mass fraction of polypropylene is 65%; the upper paper layer does not have an exocut unit or an incut unit, but the length is slightly longer than that of the lower one. The paper layer and the lower paper layer are provided with a number of inscribed units for the inward bending of the lower paper layer; the mass fraction of each component of the mixed fiber layer is: asbestos-free mineral fiber 30%, graphite fiber 12%, carbon fiber 12% %, basalt fiber 12%, glass fiber 12%, sizing agent 8%, auxiliary agent 14%; the mass fraction of each component of the mixed pulp layer is: wood pulp 15%, straw pulp 15%, hemp pulp 15%, reed pulp 15% pulp, 15% bamboo pulp, 10% sizing agent, 15% auxiliary agent; wherein, the sizing agent is a mixture of rosin glue and paraffin wax glue, aluminum hydroxide powder, sodium hydroxide powder, calcium sulfate powder in the ...

Embodiment 3

[0019] Adjacent two layers of the composite paperboard are bonded by a mixture of polypropylene and polyethylene, wherein the mass fraction of polypropylene is 62%; the upper paper layer is provided with several inscribed units for the orientation of the upper paper layer. Inwardly curved, the lower paper layer does not have external or internal cut units but the length is slightly shorter than the upper paper layer; the mass fraction of each component of the mixed fiber layer is: asbestos-free mineral fiber 30%, graphite fiber 11%, carbon 16% fiber, 13% basalt fiber, 15% glass fiber, 7% sizing agent, 8% auxiliary agent; the mass fraction of each component of the mixed pulp layer is: wood pulp 12%, straw pulp 14%, hemp pulp 13% , reed pulp 21%, bamboo pulp 15%, sizing agent 10%, auxiliary agent 15%; Wherein, sizing agent is synthetic sizing agent, and the mass ratio of sodium hydroxide powder, calcium sulfate powder is 1.3 in the auxiliary agent: 1.

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...
