Embodiment
[0031] refer to Figure 1~3 , a hepa filter screen sealing process, comprising the following steps:
[0032] S1, the inner surface of the frame groove 5 of the frame body 1, the outer surface of the screen plate 2, and the inner surface of the plate groove 6 are all sprayed with a layer of bottom spray paint, and the paint spray material includes the following components in parts by weight: 58 parts of acrylic resin, titanium 4 parts of tetrabutyl ester, 9 parts of hydroxyethyl cellulose, 7 parts of nano-titanium dioxide, 8 parts of hydroxyapatite, 6 parts of diopside, 5 parts of polymerized tung oil, 21 parts of non-leafing aluminum powder slurry, persimmon tannin 8 parts, 88 parts of deionized water, 15 parts of other additives;
[0033] S2. Heat component A of the foam sealant at a constant temperature of 45°C for 8 minutes, inject it into the plate groove 6 and cover the piston plate 4;
[0034] S3. After heating component B of the foam sealant at a constant temperature ...

The invention discloses a hepa filter screen sealing process and a sealing structure thereof. The hepa filter screen sealing process comprises the following steps: spraying a layer of bottom layer spray paint on the inner surface of a frame groove of a frame body, the outer surface of a screen plate and the inner surface of a plate groove, heating a foaming sealant component A at a constant temperature of 45 DEG C for 8 min, then injecting the foaming sealant component A into the plate groove, and covering a piston plate; heating a foaming sealant component B at a constant temperature of 60 DEG C for 10 minutes, and injecting the heated foaming sealant component B into the frame groove; and extruding the screen plate into the frame groove of the frame body and pushing a piston to extrude the foaming sealant component A into the plate groove for 20min to finish the whole sealing process. The method has the advantages that: when the sealing structure extrudes a part of the screen plate into the frame body, a limiting plate deflects upwards and does not generate any limiting effect on the screen plate, otherwise, if the screen plate needs to be pulled out of the frame body, the sharpstructure of the limiting plate can tightly clamp the screen plate so that the screen plate cannot be disengaged, and the situation that the screen plate is disengaged from the frame body due to handloosening in the pressing process is avoided.
Description
technical field [0001] The invention relates to the technical field of HEPA filter screen sealing, in particular to a HEPA filter screen sealing process and a sealing structure thereof. Background technique [0002] HEPA (High efficiency particulate air Filter), Chinese means high-efficiency air filter, the characteristic of HEPA net is that air can pass through, but fine particles cannot pass through, so as to achieve the filtering effect of air; with the rapid development of China's industry, the atmosphere Pollution is also becoming more and more serious. In order to improve the daily life and working environment, air purifiers, fresh air systems, HVAC systems, and purification projects are widely used. The main filter element is the HEPA filter. [0003] In the prior art, the HEPA filter is installed at the air inlet of the equipment, and the front-end pretreatment filter assembly is usually configured during installation. The equipment installed with HEPA filter relies...
