PRODUCTION AND EVALUATION OF LOWER BASIS WEIGHT IPC 1478 FILTER PAPER.
Abstract
The research was directed toward production and evaluation of IPC 1478 paper of reduced basis weight. It was possible to produce the filter paper at a basis weight of a little over 8 pounds per 1000 sq. ft. which is about 1/4 of the basis weight of the original IPC 1478 paper. The filtration efficiency and flow-pressure drop relationship was determined using the wind tunnel and aerosol detector described in DASA Report No. 1168. The retention of particles by the reduced basis weight paper was appreciably lower than that for the original basis weight IPC 1478 paper, as was expected. The pressure-drop across the reduced basis weight filter at a given flow was also decreased. A portion of the paper produced was impregnated with Kronisol and data were obtained on both the impregnated and unimpregnated paper. The data show that the Kronisol impregnation does not affect the retention or flow-pressure drop characteristics appreciably under the conditions of testing. (Author)
