Problems solved by technology

For humidification filters made of resin plates, disc-shaped filter substrates are generally prepared by means such as injection molding using a mold, and then hydrophilized by dipping, etc., but this method is applied to film-shaped filter substrates. When the filter base material is weak, there may be problems related to breakage such as bending of the filter base material and formation of damage.

Embodiment 1

[0121] (filter substrate)

[0122] A polyethylene terephthalate film (hereinafter referred to as "PET film") having a thickness of 250 μm was used.

[0123] (coating of hydrophilic layer)

[0124] The following materials were mixed with a mixer to prepare a coating liquid for a hydrophilic layer.

[0125] Colloidal silica

[0126] (manufactured by Nissan Chemical Industry Co., Ltd., trade name: Snowtex (registered trademark) 20, 20% liquid) 70 parts

[0127] Styrene-butadiene copolymer resin

[0128] (manufactured by JSR Corporation, trade name: 3600H, 50% liquid) 30 parts

[0129] Silane coupling agent (3-aminopropyldimethoxymethylsilane) 1 part.

[0130]After transferring to the above-mentioned PET film with a gravure roll to which the coating liquid for a hydrophilic layer adhered, it was dried and coated with a hydrophilic layer having a thickness of 3 μm on both sides.

[0131] (Preparation of filter for humidification)

[0132] A circular (diameter: 141 mm) punchi...

Embodiment 2

[0136] (Preparation of filter for humidification)

[0137] The PET film coated with the hydrophilic layer prepared in Example 1 is subjected to circular (141 mm in diameter) punching, and an opening (16.1 mm×10.1 mm) is formed in the center as a shaft through the punching process. hole 2. like Figure 8 As shown, 58 sheets of humidification filters 1E and 1F in which 16 protrusions (bowl-shaped) were formed on the filter substrate by extrusion were prepared. Protrusions 3A indicated by solid lines and protrusions 3B indicated by dotted lines are respectively formed on opposite surfaces of filter base material 10 . In addition, the protrusions of the humidification filters 1E and 1F are shifted by 45° in the circumferential direction. In the protrusions 3A and 3B, the diameter of the lowermost part was 5.0 mm, and the height was 1.5 mm. The obtained humidification filter had no defects such as bending.

Embodiment 3

[0141] (Preparation of filter for humidification)

[0142] The PET film coated with the hydrophilic layer prepared in Example 1 is subjected to circular (141 mm in diameter) punching, and an opening (16.1 mm×10.1 mm) is formed in the center as a shaft through the punching process. hole 2. like Figure 4 As shown, 58 sheets of humidification filters 1C and 1D in which eight protrusions 3 (bowl-shaped) were formed only on one side of the filter substrate 10 were prepared by extrusion. The protrusions 3 of the humidification filter 1C and the protrusions 3 of the humidification filter D are respectively provided in circular shapes with different radii, and the mutual protrusions 3 may not overlap even when adjacent to each other. In addition, the diameter of the lowest part of the protrusion part 3 was 5.0 mm, and the height was 1.5 mm. The obtained humidification filter had no defects such as bending.

Abstract

Filter substrates are each provided with multiple protruding parts, and the disclosed humidifier filter comprises multiple such filter substrates which are laminated together and used as a humidifier filter laminate body. Said protruding parts are formed by applying pressure to portions of the substrates. Even using light-weight thin film-shaped filter substrates in the humidifier filter, space can be secured between neighboring humidifier filters. By this means, the filter substrates are not prone to damage during the manufacturing process, and humidification is not decreased.

Description

technical field [0001] The present invention relates to a humidification filter and a humidification filter laminate. Background technique [0002] As a humidification filter used in a humidifier, there is a humidification filter in which a part of a water-absorbing sheet-shaped humidification filter is immersed in a water tank, water is sucked in by capillary action, and dry air is passed through to obtain humidified air. (For example, refer to Patent Document 1). However, with the humidification filter that absorbs water by capillary action, there is a problem that if compounds containing elements such as silicon, calcium, and magnesium in the supplied water form scales and adhere to the humidification filter, the water will be sucked in. effect is reduced and the humidification performance is reduced. [0003] In order to solve such problems, a humidification filter has been proposed in which a hydrophilic inorganic compound is supported on a low-water-absorbing foam su...
