Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] In all the embodiments, the aluminum honeycomb panels used in the formaldehyde-removing air purification filter element based on the inclined-hole aluminum honeycomb panels all adopt aluminum substrates with a length and width of 30 cm to 20 cm, and the thickness of the aluminum honeycomb panels is 0.5-1.5 cm. The aluminum substrate is a plate-shaped body composed of hexagonal channels, and the angle between the hexagonal channels and the vertical direction of the front of the plate-shaped body is 5-20 degrees. The components of the formaldehyde removal coating include activated carbon, calcium peroxide, calcium oxide, manganese dioxide, potassium carbonate, and adhesive. The formaldehyde removal coating is coated on the inner surface of the hexagonal channel of the aluminum honeycomb panel and cured to form a formaldehyde removal layer.

Abstract

The invention discloses a formaldehyde-removing and air-purifying filter core based on an inclined-hole aluminum honeycomb plate. The formaldehyde-removing and air-purifying filter core based on the inclined-hole aluminum honeycomb plate comprises a formaldehyde-removing coating and an aluminum honeycomb plate. The aluminum honeycomb plate is a plate-like body consisting of hexagonal pore passages; and an included angle between each of the hexagonal pore passages and a vertical direction of the front side of the plate-like body is 5-20 degrees. The formaldehyde-removing coating is prepared by coating, drying and solidifying a formaldehyde-removing dope onto inner surfaces of the hexagonal pore passages. The formaldehyde-removing dope is a mixture. Ingredients of the mixture comprise active carbon, calcium peroxide, calcium oxide, manganese dioxide, potassium carbonate, and an adhesive. The invention further discloses a preparation method of the formaldehyde-removing and air-purifying filter core based on the inclined-hole aluminum honeycomb plate. The provided formaldehyde-removing and air-purifying filter core based on the inclined-hole aluminum honeycomb plate is able to achieve a formaldehyde-removing rate of up to 93% within 2.5 minutes, and a formaldehyde-removing rate in the air of up to 100% within 10 minutes. Comparing to grained formaldehyde-removing fillers, the windage resistance is reduced by 98%. The formaldehyde-removing and air-purifying filter core based on the inclined-hole aluminum honeycomb plate is characterized in a high formaldehyde-removing efficiency, a high-temperature resistance, a low air resistance, anti-corrosion property, a long service life, and the like.

Description

technical field [0001] The invention relates to a design and preparation method of a formaldehyde-removing air purification filter element. The filter element can be used in various air purifiers, air conditioners and fresh air systems. Background technique [0002] Modern people spend more than 90% of their time indoors or in cars. In a limited space, the pollution of volatile organic compounds (VOD) seriously endangers the health of modern people. Formaldehyde pollution, as the main VOD pollution, has received extensive attention. The source of formaldehyde is more complex, mainly including urea-formaldehyde / phenolic resin wood-based panels, or plywood containing formaldehyde, blockboard, medium density fiberboard and particle board, composite flooring; decorative materials containing formaldehyde, such as wallpaper, paint, adhesives; during the manufacturing process Uses formaldehyde and may have residual textile fibers, dyes, cleaning agents, etc. [0003] Due to its...
