WOVEN FILTERING NET Russian patent published in 2001 - IPC

FIELD: pharmaceutical, petrochemical and other industry branches, namely, filtering members for finely purifying gases and liquids by removing suspended solid particles, production of porous net materials and other goods of national economy. SUBSTANCE: net has warp and weft of metallic filaments. Structure parameter of woven net is no less than 4 and it is related with parameters of net by next relation: P_c = (P_oP_ud_o)²(d_o+d_ut_u/R_o)(d_ud_ot₀/R_u), where P_c c is structure parameter of woven net; P_o is close weave of filaments along warp (1/cm); P_u is close weave of filaments along weft, (1/cm); do is diameter of warp filament, cm; dy is diameter of weft filament, cm; Ro is pattern repeat of weave along warp; Ry is pattern repeat along weft; to is number of warp overlapping in pattern repeat along warp; ty is number of weft overlapping in pattern repeat along weft. Such net provides filtering of suspended particles with size no less than 8.33 micrometer at purifying factor equal to 98.4%. EFFECT: enhanced quality of purification of gases and liquids due to improved structure of net. 2 dwg, 1 tbl, 1 ex
