When using high-efficiency filter glue, some customers will ask what methods can be used to improve the sealing effect of the high-efficiency filter. In fact, the poor sealing effect of the high-efficiency filter is caused by many aspects, not just the high-efficiency filter itself. Quality issues. Next, the editor of Weigu will talk about how to improve the sealing effect of high-efficiency filters for your reference, so as to effectively improve the sealing effect of the filter.
1. By using the negative pressure leakage sealing method, the contaminated air in the positive pressure space is transmitted to the negative pressure space outside the work area through human intervention to ensure that the work area is not contaminated.
2. Contact packing sealing method. This method uses solid gaskets as sealing fillers, such as neoprene rubber, closed-cell sponge rubber sheets, etc., and liquid sealants, such as silicone rubber and chloroprene. Rubber, natural rubber, etc. Solid sealing gaskets usually use the sealing method of mechanical compression of bolt nuts. The compression amount of rubber sheets is generally 30%-50%. Liquid sealant seals by filling and adhering. This sealing method is also the most commonly used sealing method in clean rooms.
3. Liquid groove mouth sealing method. This method is to inject a certain height of non-Newtonian sealing liquid into the groove frame, and the mouth of the high-efficiency filter is inserted into the sealing liquid to make the air on both sides The passage is blocked to achieve sealing purpose. This sealing method has strong reliability and is easy to disassemble and assemble the filter. It is usually used in clean room sealing of Class 100, Class 10 and higher cleanliness levels.
The above are the tips for improving the sealing effect of high-efficiency air filter glue introduced by Shanghai Weigu Chemical Products Co., Ltd. I hope it will be helpful to everyone. To learn more about high-efficiency air filter products, please call: 15221366737
