High-efficiency air filter filtration accuracy improvement method
High-efficiency air filter filtration accuracy improvement methodIf you want to improve the sealing of high-efficiency air filters can only use a good bit of sealing strips and sealant, what methods can be used to improve the sealing effect of high-efficiency filters, poor sealing effect of high-efficiency filters is caused by several aspects, and is not just a high-efficiency filter's quality problems.First, through the use of the negative pressure leakage sealing method, the positive pressure space of the contaminated air, through human intervention means of transmission to the negative pressure space outside the work area, to ensure that the work area is not contaminated; Second, the contact packing sealing method, this method is to seal the packing with solid gaskets, such as closed-cell sponge rubber plates, etc., as well as liquid sealants, such as: silicone rubber, and natural rubber, etc., solid gaskets are usually used in the sealing method of the mechanical compression of the mother of bolts, rubber plate compression is generally 30% 6-50%, the liquid sealant is relying on the filler and adhesion method of sealing, sealing methods are also more commonly used sealing method in the clean room. The sealing method is also the more commonly used sealing method in the cleanroom. Third, the liquid groove mouth sealing method, this method is in the groove-shaped frame, injected with a certain height of non-Newtonian sealing liquid, the mouth of the pharmaceutical factory high-efficiency filter inserted into the sealing liquid, so that both sides of the air path is blocked, to achieve the sealing purpose, the reliability of this sealing method is strong, the filter is easy to dismantle and install, usually used in the cleanroom sealing of class 100, class 10 and higher level of cleanliness. |
