Abstract

The invention provides a composite papermaking pulp substrate and a manufacturing method of the composite papermaking pulp substrate. The substrate comprises a surface layer, a core layer and a bottom layer. The surface layer is made from bamboo fiber, cane syrup fiber and powdered activated carbon. The core layer is made from bamboo fiber, cane fiber, modal fiber, jute pulp fiber and coal slag particles. The bottom layer is made from bamboo fiber, ramie pulp fiber and cane syrup fiber. The manufacturing method of the composite papermaking pump substrate includes the steps of repulping, pulp matching, high-concentration sand removing, low-concentration sand removing, pressure screening, slushing, composite papermaking with pulp, drying and the like. The composite papermaking pulp substrate and the manufacturing method of the composite papermaking pulp substrate have the advantages that waste from bamboo and hemp product machining, food processing and spinning production and coal slag discharged by coal burning are used for manufacturing the pulp substrate; when the pulp substrate is used as filter material, suspended solids and particles in water can be well filtered out, organic particles and insoluble inorganic impurities can further be removed, and the effect of chemical oxygen consumption is reduced; waste water is not discharged out in the technological steps, and required water can be used cyclically.

Description

technical field [0001] The invention relates to the technical field of pulp production, in particular to the technical field of pulp production of a pulp substrate. Background technique [0002] Various pulp papermaking composites and multi-layer laminated net papermaking are mostly limited to the technical field of papermaking. [0003] CN101225627B discloses a "method for preparing gas-phase anti-rust paper from industrial solid waste fibers" (application number 200810017337.8), and its content relates to the preparation method of face pulp and core pulp. It adopts one-step copying method. The method is to send the batter into the upper and lower fourdrinier headboxes of the three-fold wire to form the upper layer and the lower layer, and at the same time integrate the core pulp into the inclined wire headbox to form. The diamond-shaped mesh cloth woven by the weaving machine is integrated into the inclined wire part through the inclined wire headbox to form a core layer....
