EXAMPLES

A specific embodiment according to the present invention will be described with reference to the drawings. The present invention relates to an air purifier filter and a method of manufacturing the same, in which a frame is manufactured by attaching an adhesive 15 to a thick nonwoven fabric 12, 13, 16, and 17 and fixing it to the edge of a filter paper.

The process for achieving the present invention includes a process of manufacturing a sheet by bending the nonwoven fabric to the same mountain height using a bending machine, and a nonwoven fabric having a high degree of thickness on the outer surface of the sheet produced by bending with a certain mountain height. Non-woven fabric having a thickness of (a) to be formed slightly wider than the width of the space to apply the adhesive (15), and the width direction of the width (by using the non-woven fabric having a high degree after the adhesive 15 is applied) And a step of adhering to both sides in a direction parallel to the acid of the room), and cutting both ends in accordance with the width of the room for the non-woven fabric having a high degree of adhesion after the width direction.

And a step of inserting the tool into a tool for maintaining a constant acid gap in the frame-bonded space by using a thick nonwoven fabric 12 and 13 in the width direction. After fixing the acid of the room by the fixed by fixing it, and then attaching the adhesive to the thick non-woven fabric (16, 17) serving as a frame to fix the acid side of the room at the same time and fixed at the same time And a step of bonding and fixing the non-woven fabric frame having a high thickness to the acid, and cutting the high nonwoven fabrics 16 and 17 bonded to the sheet in the longitudinal direction to the length of the sheet. It is a manufacturing method of the filter for air, and relates to the filter for air cleaners produced by the said manufacturing method.

The thick nonwoven fabric used as the frame has a width of 0.5 mm to 3 mm wider than the bent acid height to apply the adhesive as a whole so that even if an error occurs during the process, the gap between the frame and the frame It is preferable to configure so that a gap does not arise.

The thick non-woven fabric 12, 13, 16, 17 attached to the outer surface of the margin to serve as a frame has a predetermined thickness when acting on the frame while being coupled to the frame of the air cleaner by elasticity. It is desirable to design and manufacture so that a gap does not arise.

In the case of manufacturing the air purification filter by the above process, by bonding the last ends of the pack with a paper frame that has been bending the conventional frame (bending) space, that is, the space that does not actually play an air purification role, that is, slope (Dead) It improves the performance of the overall filter by preventing the occurrence of space), and does not require the preparation work for bonding the paper frame during the conventional manufacturing process, thereby reducing the overall process number by 1/3, and also mechanizing and It is easy to implement automation, which can maintain a certain quality and high productivity, and greatly reduce the overall production cost.

According to the present invention, the filter was measured using a tool that maintains a constant mountain spacing, and the performance of the filter was measured in comparison with a frame and a paper frame method designed and manufactured using a thick nonwoven fabric. same.

Most air purifier filters are greatly affected by the air condition, and when the air is wet or dry, the filter varies depending on the material of the frame. It also has a big impact on the efficiency of the filter. Table 1 shows the test results of the heat resistance of the filter having a non-woven fabric (12, 13, 16, 17) frame having a thick back according to the present invention and the air purification filter attached to the edge of the paper filter, Table 2 is the present invention The filter having the nonwoven fabric 12, 13, 16, and 17 having a thickness according to and the air purifying filter having a paper frame attached to the edge of the filter were put into water for 1 hour and then taken out to show the test result of moisture resistance. Table 3 shows the values of the filter having a nonwoven fabric (12, 13, 16, 17) frame having a back thickness according to the present invention and the filter after the experiment in Table 2 at 24 ° C for 24 hours at the edge of the filter. .

Table 1. Test results of the heat resistance of the filter having a non-woven fabric frame having a back thickness according to the present invention and the air purification filter attached to the edge of the filter paper filter

Table 2 shows the test results of the moisture resistance of the filter having a non-woven fabric frame having a back thickness according to the present invention and the air purification filter with a paper frame attached to the edge of the filter paper.

Table 3 shows the dimensional change after 24 hours at 30 ° C. for a filter having a non-woven fabric frame having a back cover according to the present invention and an air purification filter having a paper frame attached to the edge of the filter.

As can be seen from Table 1, in the heat resistance test, the paper frame method was subjected to a heat test, and shrinkage of 1 mm in the longitudinal direction and 2 mm in the width direction before and after the test was observed, so that the unpurified air leaked through the gaps. It can be seen that the case of outgoing, in contrast to the frame filter designed by the nonwoven fabric having a thick fabric according to the present invention in contrast, it can be seen that no shrinkage in the length and width direction at all.

Table 2 shows the results of the moisture resistance test that has the greatest effect on the performance of the filter having a non-woven fabric frame having a thick back according to the present invention and the air filter attached to the edge of the paper filter. It can be seen that both the paper frame and the nonwoven frame have no shrinkage in the length and width directions. Table 3 is the data measured by taking out the sample put into water for 1 hour after leaving it at 30 degreeC for 24 hours, and it can be seen that Table 1 contracted 1 mm in the width direction by 2 mm in the longitudinal direction. In the case of the nonwoven fabric 12, 13, 16, 17 having a thickening according to the present invention it can be seen that there is no shrinkage even after 1 hour has passed after submerged in water.

Considering the above experimental results, it can be seen that the hygroscopicity, which is a basic property of paper, has a great influence on the experimental results. The high hygroscopicity of the paper material tends to shrink more than the original length when dried after containing moisture. In the case of air cleaner filters that are formed by inserting a filter into the injection mold, A gap is generated between the injection molding product and the filter, which causes an air passage that leaks between the gaps generated without purifying the air. The occurrence of such a gap is basically a structural defect, not a performance aspect, in an air purifier filter having high efficiency.

In the case of the air purifying filter having a high thickness nonwoven frame designed and manufactured according to the present invention, as shown in Tables 1 to 3, no shrinkage or elongation of only 1 mm was found in the heat and moisture resistance tests. . Since the material of the nonwoven fabric material and the nonwoven fabric frame is made of a polymer chemical having low hygroscopicity, it is possible to prevent the filter from contracting or expanding due to moisture present in the air. In addition, the high-quality nonwoven fabric fills the gap between the air purification filter and the injection material inserted by the filter, thereby preventing all air gaps.

Next, look at the efficiency test and the air leakage test results of the air purifying filter having a high thickness of the nonwoven frame designed and manufactured according to the present invention and the filter for the air cleaner manufactured by the paper frame method. In order to measure whether the air is leaked by using the two types of air purification filters, the dust of 3.0 μm to 2.0 μm is introduced and the wind speed is a constant amount of 10 g / min at a speed of 1.0 m / sec. Was added to measure the number of leaking dust. In the case of a filter designed by attaching a paper frame to a conventionally used edge, it can be confirmed that a large amount of dust is leaked out. This is because, as in the above-described problems of the related art, in the case of the paper frame type structure, there is a problem that air containing dust leaks between the gap generated between the air purification filter and the frame inside the air purifier to be inserted. .

Next, it looks at the efficiency of collecting dust with the air purifying filter having a high degree of non-woven fabric frame designed and manufactured according to the present invention and the filter for air cleaner manufactured by the paper frame method. The air purifying filter having a high-thickness nonwoven frame designed and manufactured according to the present invention can be used as a filter to the edge of the filter paper and has a large dust collecting area because no adhesive is used to fix the acid and acid of the filter paper. It has a higher collection rate than an air cleaner filter composed of a paper frame.

Nanotech / well-being is a term often used, and in particular, the term well-being is associated with many harmful substances that occur in various equipments and furniture that exist around people in relation to health. As the industrialization becomes more important and the industrialization is advanced, fine and sophisticated products are made, which are not harmful to the human body or beneficial to the human body. Air cleaners are often used to reduce the incidence of atopy in young children and to provide air to people by providing comfortable and clean air in the room.

Regarding the air cleaner, the conventional paper frame method is sensitive to moisture in the air, so that the width and width of the vertical change are severe and the amount of the adhesive used is high, which may cause harmful gas to be transferred, which is not suitable for the environment of modern society. In other words, the paper frame method requires a new alternative because of low moisture resistance, critical structural problems, and the like.

The nonwoven frame having a high degree of thickening according to the present invention may be said to be an optimal material capable of achieving a configuration capable of achieving efficient air purification by solving the problems of the paper frame as described above. That is, the thick nonwoven fabric frame according to the present invention has a durability against the conditions of various air cleaners, a process of simplifying the sealing process with the air cleaner frame, which was not seen in the paper frame, and the existing production process of various stages. The high productivity and low process cost by automation of the system can be pursued, and the improved performance and stable products can be supplied.
