HIGH-EFFICIENCY FILTER DEVICE AND METHOD FOR MAKING SAME
摘要
A high-efficiency filter (20) for removing or collecting trace levels of chemical compounds includes a randomly oriented glass substrate, a primer coating and a carbon coating. The present filter (20) is operable to sample or remove chemical compounds from the air with a high volumetric capacity while maintaining a low pressure drop across the filter substrate. A method for making the present filter (20) includes providing a glass substrate with randomly oriented glass fibers which is treated to remove any glue or other substances; the substrate is then coated with a primer including polydimethylsiloxane; and the primed substrate is then coated with a carbonaceous compound including polydimethylsiloxane.
