Problems solved by technology

The original forms of these purification materials are powder materials. After being bonded into the pores of the porous carrier, it is easy to cause the pores to be blocked. In addition, the fine powder particles are easily covered by glue and cannot be in contact with the outside air, resulting in failure to purify the air. Effect
[0006] Also do not have a kind of structural design rationally at present, purification efficiency is high, wind resistance is little, use safety, the air purification filter screen and preparation method thereof that are easy to process

Embodiment 1

[0037] see Figure 1 to Figure 2 , choose activated carbon powder as the purification material, and use the granulation process to prepare it into spherical particles with a particle size of 40 mesh as air purification particles for use. Select a block with a pore density of 15 kg / m 3 The polyurethane sponge material is used as the skeleton carrier to prepare the target pore density of 20kg / m 3 The air purification filter screen needs to increase its pore density by adding glue. According to the previous exploratory experiments, it is known that the internal pores of the framework material can accommodate air purification material particles accounting for 60% of its pore volume, that is, each square of the framework material needs to add 5Kg of glue to achieve the target void density, and the required volume is 0.6 m 3 particles of air-purifying materials.

Embodiment 2

[0042] see Figure 1 to Figure 2 , choose activated carbon powder as the purification material, and use the granulation process to prepare it into spherical particles with a particle size of 50 mesh as air purification particles for use. Select a block with a pore density of 20 kg / m 3 The polyurethane sponge material is used as the skeleton carrier to prepare the target pore density of 24kg / m 3 The air purification filter screen needs to increase its pore density by adding glue. According to the previous exploratory experiments, it is known that the internal pores of the skeleton material can accommodate air purification material particles accounting for 60% of its pore volume, that is, each square of the skeleton material needs to add 4Kg of glue to achieve the target pore density, and the required volume is 0.6 m 3 particles of air-purifying materials.

Embodiment 3

[0047] see Figure 1 to Figure 2 , select activated carbon powder as the purification material, and use the granulation process to prepare it into spherical particles with a particle size of 100 mesh as air purification particles for use. Select a block with a pore density of 23 kg / m 3 The polyurethane sponge material is used as the skeleton carrier to prepare the target pore density of 25kg / m 3 The air purification filter screen needs to increase its pore density by adding glue. According to the previous exploratory experiments, it is known that the internal pores of the framework material can accommodate air purification material particles accounting for 60% of its pore volume, that is, each square of the framework material needs to add 2Kg of glue to achieve the target pore density, and the required volume is 0.6 m 3 particles of air-purifying materials.

Abstract

The invention relates to a spongy air purifying filter mesh and a production method thereof. In the prior art, neither air purifying filter mesh which is high in purifying efficiency, small in wind resistance and convenient to process, and nor a production method of the air purifying filter mesh is available. The spongy air purifying filter mesh comprises air purifying particles. The spongy air purifying filter mesh is characterized by further comprising a binder layer and a framework carrier with a plurality of hole passages, wherein the binder layer is fixed on the hole passages of the framework carrier; the air purifying particles are evenly distributed on the binder layer when the binder layer is not dry, and are fixed on the binder layer after the binder layer is dried. The production method of the spongy air purifying filter mesh comprises the following steps: adhering a binder into the hole passages of the framework carrier through the steps of gum dipping, extruding and wind blowing; when the binder is not dry, placing the air purifying particles on the surface of the framework carrier, so that the air purifying particles enter the hole passages of the framework carrier; drying the binder to form the binder layer, so as to obtain the spongy air purifying filter mesh. The spongy air purifying filter mesh disclosed by the invention is high in purifying efficiency, small in wind resistance and convenient to process.

Description

technical field [0001] The invention relates to a spongy air purification filter screen and a preparation method thereof. The spongy air purification filter screen is mainly used in air purifiers and belongs to the field of environmental protection materials. Background technique [0002] At present, air pollution has become a common concern of the public, and there are many different types and forms of air purification products on the market. The core component of these air purification products is the purification filter element that plays a purifying role. For different purification filters, the purification filter element reacts with the internal purification material and air to remove volatile harmful gas pollutants in the air. The purpose is to realize the function of purifying the air. However, in this purification process, the denser the design of the filter screen, the more purification materials it contains, the higher its efficiency in purifying the air, but when...
