Abstract

The present invention relates to a composite electrets fiber filtering material. The present invention is made by the method as follows:(1) compound the polyfluortetraethylene membrane and the basilar membrane to form a composite material; (2) electret the composite material to form composite electrets membrane; (3) composite electrets membrane forms fiber by extending, and then the product is gained by making the fiber into net. The composite electrets fiber filtering material has the advantages of extremely high electrets electric charge stability, prominent filtering efficiency, low pressure loss, long service life, wide appliance and board service scale.

Description

(1) Technical field [0001] The invention belongs to the field of ultra-purification engineering, and in particular relates to a composite electret fiber filter material. (2) Background technology [0002] With the development of science and technology, the requirements for the environment are becoming more and more stringent. To obtain a clean space, an air purifier is often used, and the filter membrane of the purifier is an important part in the purification process. The common filter membrane is The principle is to passively block the continuous movement of large dust whose line exceeds a certain size, so as to stop it. Its function is related to the pore size of the filter material (filter membrane). Moreover, the fabric or ordinary non-woven filter material usually used has dust infiltrated into the fabric to form a primary dust layer, thereby achieving deep and effective filtration. However, as the use time increases, its resistance increases until the fabric is bloc...
