Example

[0032] Example 2. Blending of oil palm husk blasting pulp and waste paper pulp to produce A-grade corrugated base paper

[0033] The oil palm husk explosion pulp was prepared according to the production flow and process conditions of Example 1.

[0034] Waste paper pulp is made from old corrugated boxes and waste cement bags that are crushed by a high-concentration hydraulic pulper, and then passed through a heat dispersion system, sand removal, slag removal, washing, refining, and purification. The beating degree of waste paper pulp is 26-28°SR.

[0035] Ratio of pulp: 70% of oil palm shell blasting pulp, 30% of waste paper pulp. Pulp sizing: sizing the mixed pulp in the pulp mixing tank, the amount of rosin glue is 2% of dry fiber, and the amount of aluminum sulfate is 3%.

[0036] Finished product quality: Quantitative 116g / m 2 , tightness 0.55g / cm 3 , the transverse ring pressure index is 7.8Nm / g, and the longitudinal fracture length is 4450m. The quality of the finis...

[0037] Example 3: Combining oil palm husk blasting pulp with waste paper pulp and kraft wood pulp for kraft vermicelli boxboard

[0038] The preparation of oil palm husk blasting pulp is carried out according to the production process and process conditions of Example 1, and the preparation of waste paper pulp is carried out according to the production process and process conditions of Example 2. Kraft wood pulp is wood pulp made by crushing with a high-consistency hydraulic pulper, then through medium-consistency refining, screening and purification, dyeing and sizing.

[0039]Kraft wood pulp beating degree is 34-36°SR

[0040] Kraft wood pulp flavoring; dyeing and sizing in the pulp chest of the wood pulp production process. The dosage of basic orange is 0.04% of the dry fiber, and the dosage of basic bright yellow is 0.02% of the dry fiber. The amount of rosin glue is 2% of the dry fiber amount, and the amount of aluminum sulfate is 3%.

[0041] Ratio of pulp: kraft wood...

Abstract

This invention relates to a method for making the packing board through the blasting pulp, which belongs to the slurrying papermaking field. The method comprises the following steps: a) hammering, washing and stackable preprocessing the palm husk; b) adding caustic soda and adjuvant to immerse; c) setting the material in the blasting tin to steam, then discharging the slurry to the spreading chamber; d) extracting devil liquor of the slurry by the shoving mill, the devil liquor can be multi-purpose used or sent to sewage disposal place; e) backflushing pulp, purifying, grinding, seasoning, the blasting pulp single or with the waste pulp, sulfate wood pulp to make the packing board. The invention based on the biological tissue of the palm husk, through blasting to prepare pulp with low pollution, while the paper pulp has good intensity property especially high collar pressure intensity.

Description

technical field [0001] The invention relates to the technical field of pulping and papermaking, in particular to a method for producing packaging cardboard from oil palm shell blasting pulp. Background technique [0002] Oil palm is an evergreen oil-bearing tree species of the palm family. It is an arbor with a height of 15m. After the fruit is used for oil extraction, the palm shell becomes a solid residue. At present, only a small amount of palm shell is used as fuel, and in palm oil concentration In the place of origin, a large number of palm husks are either burned or piled up in the woodland and discarded, causing serious pollution to the environment. [0003] Some people at home and abroad have studied oil palm husks as raw materials for pulping and papermaking. The results of the research suggest that the chemical composition and fiber morphology of oil palm husks are similar to those of poplar wood and rice straw, so they should be used ...
