Embodiment 1

[0043] Step 1: After mixing natural sulphate softwood pulp and sulphite wood pulp at a mass percentage of 80% and 20% respectively, they are pulverized by a hydropulper and pure water, and then pumped to a beating production line for refining. The beating production line includes large taper and double disc mills; the beating degree is 35SR, the wet weight is 7.0g, and the conductivity of pure water is 18μs / cm.

[0044] Step 2: Put the ground pulp through the pulp storage tower, the transition tank, the forebay and the high level box in turn to adjust the pulp, mix it with white water, pass through the sand remover and pressure screen to remove the slag, and finally send it to the headbox; the specific steps as follows:

[0045] Step 21: The slurry storage tower adjusts the ground pulp into a slurry with a concentration of 3.5%, and sends it to the transition tank through the slurry pump;

[0046] Step 22: The concentration pump in the transition tank adjusts the concentratio...

Abstract

The invention discloses a production method of natural-color anti-rusting body paper. The production method comprises the following steps: (1) mixing natural-color sulfate softwood pulp with sulfite wood pulp, adding pure water, and carrying out pulping; (2) sequentially blending the pulp by virtue of a pulp storage tower, a transition tank, a pre-papermaking tank and a high-level tank, mixing theblended pulp with white water, removing residues by virtue of a sand filter and a sucking-moving roll, and finally, conveying the pulp to a flow pulp tank; (3) uniformly distributing the pulp to a net by virtue of the flow pulp tank, dehydrating by virtue of a net part, so as to obtain a wet paper blank; (4) sucking and moving the wet paper blank to coarse cotton cloth by virtue of the sucking-moving roll, and carrying out three squeezing dehydration processes, so as to obtain wet paper; (5) introducing the wet paper to a drying part by virtue of a paper introducing rope, drying, and introducing the wet paper to a reeling part, discharging the wet paper from the roll while reaching a specified roll diameter after parameters are qualified; and (6) re-reeling the wet paper into a specifiedspecification by virtue of a re-reeling machine after discharging. The natural-color anti-rusting body paper produced by virtue of the production method is high in yield, low in energy consumption, good in water-absorbing quality, high in strength, stable in moisture and uniform in thickness.

Description

technical field [0001] The invention relates to the field of natural color pulp production, in particular to a production method of natural color antirust base paper. Background technique [0002] The current pulp production methods mainly include chemical, semi-chemical, mechanical and chemical-mechanical processes. Anti-rust paper is widely used, but domestic manufacturers of natural-color anti-rust base paper generally can only produce low-grade anti-rust base paper, which has low output, high dust, poor strength and low water absorption, and the use effect is not good. Contents of the invention [0003] In order to overcome the problems of low output, high dust, poor strength and low water absorption of colored antirust base paper in the prior art, the invention provides a production method of natural color antirust base paper. [0004] The specific technical scheme is as follows: [0005] A production method of natural color antirust base paper, [0006] Step 1: Af...
