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 6 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. 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 connected in sequence. The m...

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 the hydraulic pulper, the pulp residue in the slurry is removed through the high-concentration cleaner and the medium-concentration cleaner in turn, and then sent to the single-effect fiber separator, and the fiber is broken by the blade and the impeller. , and then the slurry that passes through the sieve plate under a certain pressure becomes the effective slurry ya2. The waste slurry discharged from the single-effect separator enters the slag discharge separator. After the waste residue is removed, the remain...

Embodiment 3-7

[0174] Embodiment 3-7 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 following table:

Abstract

The invention discloses a bobbin paper production system and a corresponding production process. The production system includes a high-grade bobbin paper production line and a middle-grade bobbin paper production line; the high-grade bobbin paper production line includes a pulping module I and a papermaking module I; a papermaking module I The press device I includes one to four press roll assemblies I arranged in a horizontal line. The one-to-four-stage press roll assembly I of the present invention increases the press nip through which the paper sheet passes, and strengthens the compaction force of the paper sheet. Inter-bonding force up to 800J / m 2 ; In addition, use the pulp made from the waste slag in the high-grade bobbin paper production line and the pulp made from the waste cardboard to mix in proportion to make the bobbin paper raw pulp, which not only turns waste into treasure, but also The prepared bobbin paper has high strength, and the bonding force between layers can reach 600J / m 2 , the transverse ring pressure index can reach 20N·m / g. The high-grade and middle-grade bobbin paper production lines of the present invention are respectively suitable for producing bobbin paper for spinning 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,...
