Embodiment 1

[0094] Embodiment 1 bobbin paper production system

[0095] A bobbin paper production system includes a high-grade bobbin paper production line and a middle-grade bobbin paper production line.

[0096] 1. High-grade bobbin paper production line includes pulping module Ⅰ and papermaking module Ⅰ.

[0097] (1) Pulping Module I

[0098] Pulping module I includes pulping equipment I for manufacturing pulp y made from waste cardboard, such as Figure 5 shown.

[0099] Pulping equipment I includes hydraulic pulper, high-consistency slag remover, medium-consistency slag remover, single-effect fiber separator, short-fiber pulp separation device, medium-fiber pulp separation device, and long-fiber pulp separation device connected in sequence. The output end of the effective fiber separator is also connected with the slag separator.

[0100] The fluff pulp separation device includes a first grading screen, a fluff pulp tank, a low-consistency slag remover, and a pulp refiner conne...

Embodiment 2

[0140] A kind of bobbin paper production process, it realizes based on the bobbin paper production system of embodiment 1, comprises the following steps:

[0141] A2. Preparation of pulp y2; B2. Dehydration forming of wire part; C2. Pressing; D2. Drying; E2. Calendering; F2. Roll paper; G2. Preparation of pulp x2; Forming; G2. Pressing; K2. Drying; L2. Calendering; M2. Roll paper.

[0142] A2. Preparation into slurry y2

[0143] After the waste cardboard is pulped by a hydraulic pulper, it is successively passed through a high-concentration cleaner and a medium-concentration cleaner to remove pulp residue in the slurry, and then sent to a single-effect fiber separator for fiber separation to separate effective slurry After ya2 and ya2 enter the fiber separator, the fibers are disintegrated by blades and impellers, and then the slurry that passes through the sieve plate under a certain pressure becomes effective slurry. The waste slurry discharged from the single-effect separ...

Embodiment 3-6

[0174] Embodiment 3-6 is a kind of bobbin paper production process respectively, and their difference with embodiment 2 is only that the control parameter in its production process is different, specifically as shown in the table below:

Abstract

The invention discloses a system and a corresponding process for manufacturing bobbin paper. The system for manufacturing the bobbin paper comprises a high-grade bobbin paper manufacturing line and a medium-grade bobbin paper manufacturing line. The high-grade bobbin paper manufacturing line comprises a pulp producing module I and a module I for manufacturing paper with pulp; a squeeze device I of the module I for manufacturing the paper with the pulp comprises a primary squeeze roll assembly I, a secondary squeeze roll assembly I, a tertiary squeeze roll assembly III and a fourth-level squeeze roll assembly I which are horizontally straightly arrayed. The system and the corresponding process have the advantages that paper sheet passing squeeze pressure zones can be enlarged by the aid of the primary squeeze roll assembly I, the secondary squeeze roll assembly I, the tertiary squeeze roll assembly III and the fourth-level squeeze roll assembly I, paper sheet compacting force can be increased, a transverse ring crush index of the bobbin paper manufactured by the aid of equipment of the system can reach 22N m / g, and interlayer binding force can reach 800J / m<2>; finished pulp made of waste pulp residues in the high-grade bobbin paper manufacturing line and finished pulp made of waste paperboards are proportionally mixed with each other to obtain the primary pulp for the bobbin paper, accordingly, the waste pulp residues can be turned into wealth, the manufactured bobbin paper is high in strength, interlayer binding force can reach 600J / m<2>, and a transverse ring crush index can reach 20N m / g; the high-grade bobbin paper manufacturing line and the medium-grade bobbin paper manufacturing line are respectively applicable to manufacturing the bobbin paper for spun yarns and plastics.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and relates to a bobbin paper production system and a bobbin paper production process based on the system. Background technique [0002] Bobbin paper is an industrial technical paper used by chemical fiber equipment factories in the textile industry. It can be used to make filament high-speed spinning cores. It not only requires high dry strength, wet strength, smoothness and wear resistance, but also must have the characteristics of oil resistance and water resistance, and it is required to be lint-free, non-deformed, Do not burst. Based on the above characteristics, bobbin paper is required to have certain physical strength and high quantitative. [0003] In the prior art, the production process of bobbin paper includes steps such as pulping, wire dehydration forming, pressing, drying, calendering, and paper rolling. The production equipment includes dehydration devices, pressing devices,...
