Embodiment 1

[0022] The present invention provides a kind of resource utilization method of bamboo dross, specifically comprises the following steps:

[0023] Step 1: Adjust the bamboo dregs produced in the process of papermaking and pulping according to the moisture content of 6% to 12%, and then crush and grind the bamboo dregs with a speed of 3000 to 39000r / min to obtain 100-mesh bamboo dregs. material.

[0024] To make pulp, the pulp is prepared from waste corrugated cartons. First, the waste corrugated cartons are fully disintegrated in a beater. After disintegration, the pulp is beaten with a PFI refiner, and the degree of beating is controlled at 18-30 O Sr.

[0025] Step 2: Take the pulp in step 1 and add bamboo residue fines of 5% of the pulp mass to it to obtain a pulp slurry, add water to dilute to obtain a pulp slurry with a pulp concentration of 0.1% to 0.5%, and stir in a pulp decomposer After 5 minutes, add 0.5% of the pulp mass as a retention aid cationic starch and 1% of...

Abstract

The invention discloses a resource utilization method of bamboo residues, which specifically comprises the following steps: 1, regulating the water content of the bamboo residues to 6-12%, and pulverizing and grinding the bamboo residues to obtain 100-300 mesh bamboo residue fine materials; 2, preparing paper pulp with the beating degree of 18-30 OSR, adding a bamboo residue fine material accounting for 5%-25% of the mass of the paper pulp into the paper pulp to prepare a mixture, adjusting the pulp concentration of the mixture to be 0.1%-0.5%, uniformly stirring the mixture, adding retentionaid cationic starch accounting for 0.5% of the mass of the paper pulp and reinforcing agent polyacrylamide accounting for 1% of the mass of the paper pulp, and uniformly stirring the mixture to obtainpapermaking pulp; 3, making the papermaking pulp obtained in the step 2 into a wet paper sheet according to the amount of 100g / m2, and then uncovering, squeezing and drying the wet paper sheet to obtain a dry paper sheet. According to the invention, the bamboo residues are crushed and pretreated to serve as filler to be applied to papermaking production, so that the problem of bamboo residue discharge is solved, the papermaking raw material cost is reduced, and the paper forming quality is improved.

Description

technical field [0001] The invention relates to bamboo dregs recycling technology, in particular to a resource utilization method of bamboo dregs. Background technique [0002] Papermaking is an important invention of the working people in ancient China. There are two forms of mechanism and manual. The organic mechanism is carried out continuously on the paper machine. The pulp suitable for the paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing and then dried into paper. By hand, bamboo screens, polyester nets or copper nets are used to make wet paper sheets from the fibers dispersed and suspended in water, which are dehydrated by pressing, and then dried or dried into paper. [0003] The papermaking industry uses native plant fibers such as wood, bamboo, reed, or recycled fibers such as waste paper as raw materials. During the pape...
