Purification workshop high-efficiency filter with good sealing and high precision
Purification workshop high-efficiency filter with good sealing and high precisionIf you want to improve the sealing of the purification workshop high-efficiency filter can only use a good bit of sealing strips and sealant, what method can enhance the sealing effect of the high-efficiency filter poor sealing effect of the high-efficiency filter is caused by several aspects, and not just the high-efficiency filter's quality problems, so the author, based on many years of experience, to talk about how to enhance the sealing effect of the high-efficiency filter, to effectively enhance the filter! The sealing effect of the filter.Through the use of the negative pressure leakage sealing method: the contaminated air in the positive pressure space, through the means of human intervention to the negative pressure space outside the work area, to ensure that the work area is not contaminated. Contact packing sealing method: this method is sealed with a packing solid gasket, such as a closed-cell sponge rubber plate, and liquid sealant, such as silicone rubber, natural rubber, etc., solid gasket is usually used to bolt the mother of the mechanical compression sealing method, the rubber plate of the compression amount is generally 30% -50%, the liquid sealant is by filling and adherence method of sealing, the sealing method is also a more commonly used sealing method of the clean room. Liquid slot sealing method: this method is in the slot frame, injected into a certain height of non-Newtonian sealing liquid, high-efficiency filters are inserted into the mouth of the sealing liquid, so that both sides of the air path are blocked, to achieve the sealing purpose, the reliability of this sealing method is strong, the filter is easy to dismantle and install, usually applied to the cleanroom sealing of the 100-level, 10-level and higher level of cleanliness. |
