Description

A new type of top cotton filter material

technical field

The utility model relates to the technical field of dust-proof workshop filtration, in particular to a novel top cotton filter material.

Background technique

When the painting workshop is working, the external air is filtered by the primary filter cotton and sent to the roof by the fan, and then enters the room after being filtered and purified by the filter cotton laid on the top for the second time. The air in the room adopts the full-drop type, flowing downward at a speed of 0.2-0.3m/s, so that the paint mist particles after painting cannot stay in the air, but are directly discharged out of the room through the bottom air outlet. This continuous cycle conversion makes the air cleanliness in the environment reach more than 98% when painting, and the air sent in has a certain pressure, which can form a constant airflow around the car to remove excess paint, thereby ensuring maximum protection. The quality of the paintwork.

At present, the filter cotton on the top of the paint shop is generally used as a fiber layer filter material processed by PET fiber through dry hot-melt method. The filtration efficiency of the filter cotton is improved by dipping treatment, and the air outlet surface is attached with a 40-mesh mesh to prevent Fibers shed.

Disadvantages: 1. The 40-mesh latitude and longitude mesh cloth attached to the air outlet surface of the filter cotton is bonded with adhesives. Due to the limited contact area, only increase the amount of glue to achieve the purpose of bonding firmly, and an adhesive film will be formed on the air outlet surface of the filter cotton. As a result, the ventilation resistance of the filter cotton is increased, the service life is shortened, and the operating cost of the system is increased.

2. The adhesive film formed on the air outlet surface of the filter cotton is produced in the process of high-temperature ironing, and its firmness is poor. Under the condition of long-term ventilation and 60-70°C, the adhesive film will weather and fall off, and the mesh cloth will detach, causing environmental pollution for spray paint.

3. The water-soluble adhesive used for dipping treatment is easy to breed harmful bacteria.

4. The material of the filter cotton is PET fiber, which is easy to generate static electricity in a high-temperature dry environment, which affects the stability of the airflow.

5. Because spraying and baking paint needs to be carried out at a relatively high temperature, the filter cotton is required to have corresponding high temperature resistance and flame retardancy, which provides a guarantee for safe production.

Utility model content

The purpose of this utility model is to improve the shortcomings and deficiencies of the above-mentioned prior art, and to provide a new type of top cotton filter material, so that the mesh attached to the air outlet surface is firmly and stably bonded and does not produce conjunctiva, the filtration efficiency is high, and the resistance is low. Long service life and low operating cost.

The technical scheme adopted for realizing the above-mentioned purpose is:

A new type of top cotton filter material, comprising a fine knitted mesh cloth, a filter material layer, and a water-based acrylic emulsion bonding glue; the knitted fine knitted mesh cloth is bonded to the filter material layer through the water-based acrylic emulsion bonding glue.

Knitted fine knitted mesh is woven with PET filament using knitting process.

The filter material layer 3 is composed of a loose layer 4 , an intermediate layer 5 and a dense layer 6 .

Polymer pure acrylic emulsion, antistatic agent and nano antibacterial and antifungal agent are distributed in the filter material layer.

The beneficial effects of the utility model are:

1. The new nominal 500-mesh knitted fine-knitted mesh adopts the knitting process of PET filaments. The feature of this process is that the threads are looped, hooked, three-dimensional, and overlapped, filled with each other, reducing the diameter of the mesh, and the filtration of the filter cotton. Accuracy increased by 1.5%.

2. With a small amount of adhesive, this new type of product can achieve the fastness of sticking to the net on the air outlet surface of the filter material layer, and does not form an adhesive film. After long-term ventilation and use, there will be no dust accumulation, and there will be no phenomenon that the mesh cloth will fall off. The service life of the filter cotton is long.

3. This new model adds flame-retardant fibers in the production of filter cotton, and the filter cotton has flame-retardant properties.

4. This new type adds antibacterial and antifungal agents and antistatic agents in the filter material layer to ensure that the filter cotton does not generate electrostatic adsorption and mildew.

detailed description

Below in conjunction with accompanying drawing and reference numeral the utility model is described in further detail.

As shown in Figure 1-3,

A new type of top cotton filter material, comprising a fine knitted mesh 1, a filter material layer 3, and a water-based acrylic emulsion adhesive 2; fit together.

The knitted fine mesh 1 is nominally 500 mesh.

The fine knitted mesh fabric 1 adopts PET filament and is woven by a knitting process.

The filter material layer 3 is composed of a loose layer 4 , an intermediate layer 5 and a dense layer 6 .

Polymer pure acrylic emulsion 7, antistatic agent 8 and nano antibacterial and antifungal agent 9 are distributed in the filter material layer 3.

Example

The three-dimensional space between the silk threads is formed in the novel knitted fine-woven mesh cloth 1, and a small amount of laminating glue can be used for fastness of sticking to the air outlet surface of the filter material layer 3 without forming a glue film. After long-term ventilation and use, no dust will be produced, and there will be no phenomenon that the mesh will fall off.

The filter material layer 3 is made of three-dimensional immersion polymer pure acrylic emulsion 7, nano antibacterial and antifungal agent 9 (YZN-Y-500), antistatic agent 8 (FSK-2), and then dried by hot air at 150°C. Increased filtration accuracy, with anti-static, anti-bacterial and anti-mildew effects.

The filter material layer 3 is composed of three-dimensional polyester staple fibers of different deniers and flame-retardant fibers as a skeleton, and a low-melting-point fiber is used as an adhesive, and is formed by a dry hot-melt method. The filter material layer 3 forms a loose layer 4, an intermediate layer 5 and a dense layer 6 through the fiber fineness from large to small, so as to realize the cascade filtration from the air inlet to the air outlet.

The processed finished filter cotton is cut and shaped as required, and packaged.
