The utility model provides a humidification membrane is applied to air conditioning equipment's such as air conditioner, humidifier, clarifier humidification filter core, and its aim at reduces the accumulation of the incrustation scale of humidification membrane surface to slow down the decay rate of humidification volume, prolong the life of humidification membrane.
In the embodiment of the present invention, as shown in fig. 1, the humidifying membrane 10 includes a water-absorbing layer 11 and a first hydrophobic layer 12, the water-absorbing layer 11 is formed by a hydrophilic material, and the first hydrophobic layer 12 is disposed on the windward side of the water-absorbing layer 11.
It should be noted that when the cohesive force between water molecules is smaller than the mutual attraction force between water molecules and molecules of the solid material, the material is wetted by water, and such a material is hydrophilic and is called a hydrophilic material; when the cohesive force between water molecules is larger than the attractive force between the water molecules and the material molecules, the surface of the material cannot be wetted by water, and the material is hydrophobic and is called as a hydrophobic material. The utility model discloses among the technical scheme, layer 11 that absorbs water adopts the hydrophilic material to make, and this hydrophilic material includes but not limited to hydrophilic cotton, wood pulp paper and hydrophilic fibre etc.. When the water absorbing layer 11 is a film layer made of hydrophilic fibers, the water transport performance of the humidifying membrane 10 can be improved by utilizing the hydrophilicity and the capillary core structure of the surface of the hydrophilic fibers, so that the water absorbing capacity of the humidifying membrane 10 is improved.
The prior art only considers that the humidification amount of the humidification membrane is raised by increasing the water absorption amount of the humidification membrane, and therefore, the humidification membrane is entirely made of a hydrophilic material. However, the present invention finds that after the existing humidifying membrane is used for a long time, a layer of white or yellow scale is formed on the outer surface, especially the windward surface, and the scale is tightly combined with the hydrophilic material, so that the scale on the surface of the humidifying membrane is difficult to clean, and thus the scale is gradually deposited and blocks the capillary core structure of the hydrophilic material, which causes the water absorption and humidification to be gradually attenuated, thereby shortening the service life of the humidifying membrane.
And the utility model discloses technical scheme is through increasing the one deck hydrophobic layer at the windward side that absorbs water layer 11 for the surface of humidification membrane 10 absorbs water or does not absorb water less, reduces moisture content evaporation at its surface, thereby is difficult for forming the incrustation scale. Even if scale is formed on the surface, since the scale is not directly contacted with the hydrophilic layer, the scale is easily cleaned, so that the attenuation speed of the humidification quantity is slowed, and the service life of the humidification membrane 10 is prolonged.
Further, as shown in fig. 1, the humidifying membrane 10 further includes a second hydrophobic layer 13, and the second hydrophobic layer 13 is disposed on a leeward side of the water absorbing layer 11. It can be understood that, since the windward side and the leeward side of the humidifying membrane 10 are both exposed to the air, moisture on the windward side and the leeward side of the humidifying membrane is easy to evaporate to form scale, and therefore, by providing the hydrophobic layers on both side surfaces of the humidifying membrane 10, both side surfaces of the humidifying membrane 10 are not water-absorbing, thereby preventing scale from being formed due to moisture evaporation. In addition, the hydrophobic layers are arranged on the two side surfaces of the humidifying membrane 10, so that a user can conveniently replace the humidifying membrane 10 in the air conditioning equipment, and in the installation process, the user does not need to distinguish the two side surfaces of the humidifying membrane 10 and specially arranges one side surface of the humidifying membrane with the hydrophobic layers towards the air inlet. Of course, in other embodiments, the hydrophobic layer may be disposed only on the windward side of the water absorbing layer 11, and the hydrophobic layer may be marked to facilitate the user to identify and dispose the side of the humidifying membrane 10 having the hydrophobic layer toward the air inlet.
Specifically, the thickness of the first hydrophobic layer 12 and the thickness of the second hydrophobic layer 13 are both 50-200 μm, the average pore diameter is 2.0-5.0 μm, and the pore density is 500-1000 ppi. The thickness of the water absorbing layer 11 is 100-500 mu m, the average pore diameter is 2.0-5.0 mu m, and the pore density is 500-1000 ppi. It is understood that the thickness of the hydrophobic layer should be smaller than the thickness of the water-absorbing layer 11 to ensure the water-absorbing amount and the humidification amount of the humidification film 10. In addition, the water absorbing layer 11 and the hydrophobic layer are both porous structures, so that the humidifying membrane 10 has good air permeability, when wind passes through the humidifying membrane 10, moisture on the surface of the humidifying membrane 10 can be rapidly evaporated and carried away with air, and the water absorbing speed and the water absorbing capacity of the humidifying membrane 10 are increased.
Specifically, the first hydrophobic layer 12 and the second hydrophobic layer 13 are formed of hydrophobic fibers including any one or more of polytetrafluoroethylene fibers, polyvinyl acetate fibers, polyvinylidene fluoride-hexafluoropropylene fibers, polyvinylidene fluoride-tetrafluoroethylene-perfluoromethyl vinyl ether fibers, and polyvinylidene fluoride-chlorotrifluoroethylene fibers. It can be understood that the macromolecular chains of the hydrophilic fibers are mainly lipophilic organic groups, and lack a certain number of groups with stronger polarity (such as-OH, -NH, C ═ O, and the like), so that hydrogen bonding with water molecules is difficult to form, the proportion of the crystalline region is large, the amorphous region is less, the molecular structure is compact, and the water molecules are not easy to penetrate into the internal gaps of the fibers. Therefore, when the water-repellent layer made of the hydrophobic fibers is provided on the outer surface of the water-absorbing layer 11, the outer surface of the humidifying membrane 10 is less likely to absorb water and less likely to be wetted, and the outer surface thereof is less likely to be formed.
Further, the hydrophilic material is hydrophilic fiber, and the hydrophilic fiber comprises any one or more of cellulose acetate fiber, chitosan fiber, polyacrylonitrile fiber, ethylene/vinyl alcohol copolymer fiber, polyamide fiber and polyimide fiber.
Further, the hydrophilic material is a profiled fiber, and the cross-sectional shape of the profiled fiber includes at least one of a cross shape, a Y shape, a T shape, a W shape and an H shape. In the present embodiment, the water absorbing layer 11 can rapidly absorb water in the water tank 300 by using the fine grooves formed on the surface of the fiber having the irregular cross section, and instantly reach the top of the humidifying membrane 10.
Further, as shown in fig. 2 and 3, the humidifying membrane 10 is configured in a zigzag shape. Specifically, the humidifying membrane 10 may be folded alternately in two opposite directions, so that the humidifying membrane 10 forms a zigzag-shaped folded structure like a paper fan. Therefore, the contact area between the air and the humidifying membrane 10 can be increased, the moisture discharging area and the evaporation efficiency can be improved, and the humidifying quantity of the humidifying membrane 10 can be increased.
Specifically, as shown in fig. 3, the humidification film 10 having a zigzag shape has a plurality of teeth 14, the height H of the teeth 14 may be 10 to 100mm, and the density of the teeth 14 may be 150 to 500 teeth 14/m. It will be appreciated that the appropriate tooth 14 height and tooth 14 density allows for a greater amount of humidification of the humidification membrane 10 without excessive wind resistance.
Further, the humidifying membrane 10 is a nonwoven fabric composed of hydrophilic fibers and hydrophobic fibers. Specifically, the nonwoven fabric is a fabric formed without spinning a woven fabric, and is formed by only forming a fiber web structure by orienting or randomly arranging textile short fibers or filaments and then reinforcing the fiber web structure by mechanical, thermal bonding or chemical methods. The nonwoven fabric has advantages of flexibility, light weight, and air permeability, and can provide the humidifying membrane 10 with excellent humidifying effect.
In one embodiment, the nonwoven fabric satisfies the following conditions: the surface wetting grade is in the range of 2-5. The surface wetting grade of the humidifying membrane 10 is related to the material, pore diameter and porosity of the hydrophobic layer. The utility model discloses refer to GB/T4745-2012 standard and be stained with the water grade to humidification membrane 10's surface and test to the hydrophobic performance on evaluation humidification membrane 10 surface. The GB/T4745-2012 standard describes the wetting behavior of different wetting grades as shown in Table 1. As can be seen from table 1, the higher the wetting grade is, the less moisture is adhered to the surface of the humidifying membrane 10, and the better the hydrophobic property of the surface of the humidifying membrane 10 is.
TABLE 1 description of the wetting behavior for different wetting grades
In one embodiment, the humidifying membrane 10 is a non-woven fabric manufactured by an electrospinning technique, and the manufacturing process is as follows: firstly, hydrophobic fibers are deposited on a receiving substrate by an electrostatic spinning method to form a first hydrophobic layer 12; then, depositing hydrophilic fibers on the first hydrophobic layer 12 by an electrostatic spinning method to form a water absorbing layer 11; finally, hydrophobic fibers are deposited on the water absorbing layer 11 through an electrostatic spinning method to form a second hydrophobic layer 13.

And (3) performance testing:
The water absorption speed, water absorption amount and humidification amount of examples 1 to 5 and comparative example 1 were measured by the following methods:
Humidification amount and humidification film 10 life test: reference is made to GB/T23332-2009.
The test results are shown in table 2:
TABLE 2 Performance test results for different humidifying membranes 10
| Surface water rating | Amount of humidification (g/h) | Humidification film service life (h) | |
| Example 1 | 5 | 400 | 1500 |
| Example 2 | 4 | 450 | 1400 |
| Example 3 | 3 | 500 | 1300 |
| Example 4 | 2 | 550 | 1300 |

| Comparative example 1 | 0 | 700 | 1000 |

This is because, when the surface of the humidification membrane 10 is not provided with the hydrophobic layer, the surface of the humidification membrane 10 absorbs a large amount of water, the water is evaporated on the surface of the humidification membrane 10 for many times to leave the scale, and the scale gradually blocks the pores of the humidification membrane 10 to affect the air permeability, thereby slowing down the evaporation rate of the water of the humidification membrane 10, further reducing the humidification amount and shortening the service life thereof. The humidification films 10 provided in examples 1 to 5 have a high surface wetting level, and the humidification amount and the service life of the humidification film 10 are both excellent. This is because, when the surface of the humidification membrane 10 is provided with the hydrophobic layer, the outer surface of the humidification membrane 10 absorbs little or no water, and evaporation of water on the surface thereof is reduced, so that deposition of scale can be reduced. Even if scale is formed on the surface of the humidifying membrane, the humidifying membrane can be easily cleaned due to the hydrophobicity of the surface material, so that the attenuation speed of the humidifying quantity is reduced, and the service life of the humidifying membrane 10 is prolonged. It should be noted that the higher the humidification level of humidification film 10 is, the less moisture is adhered to the surface of humidification film 10, and scale is less likely to be formed, so that the higher the humidification amount of humidification film 10 is, the longer the service life is.
The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
