| 摘要 |
A belt designed for lead acid battery plate pasting that is rendered dimensional Iy stable and incompressible and is also rendered hydrophobic to allow water handling without absorption and subsequent contamination of lead oxide into the structure. The belt comprises a first ply (18) of an endless fabric structure produced from high modulus monofilament yarns, a second ply (16) comprising layers of monofilament flat fabric and layers of fibrous batt, a third ply (14) of layers of batt fibers and a fourth ply (12) of monofilament endless fabric structure attached to the third ply (14) through needling. |
