Problems solved by technology

[0003] The traditional paper production process has the following disadvantages: there is no mechanism to straighten out the raw pulp during the output of the raw pulp, resulting in messy paper textures when the paper comes out at the end; large differences in the effects of the two sides of the paper; poor drying quality ;Paper tension is poor, prone to paper breaks

Embodiment 1

[0029] A paper production process, specifically comprising the following steps:

[0030] S1. Beating: the waste paper is continuously beaten, and the waste paper is pulped and beaten using a multi-cycle bin for 2 cycles of beating. In order to ensure the uniformity of the paper; Adjust the slurry inlet concentration, control the heating temperature and the gap between the heat dispersion grinding discs;

[0031] S2. Adding and stirring: feeding and stirring in the mixer, put the fully pulped and beaten pulp into the mixer, then add functional additives and stir fully, then add the slurry into the original pulp drain tube, the pulp and functional additives The input ratio is 100:6;

[0032] S3. Straighten out: transport the slurry in the raw pulp leaking barrel to the fourdrinier multi-cylinder paper machine through the straighten out device for papermaking;

[0033] S4. Paper making: use fourdrinier multi-cylinder paper machine for production, and use calender for finishing,...

Embodiment 2

[0044] A paper production process, specifically comprising the following steps:

[0045]S1. Beating: the waste paper is continuously beaten, and the waste paper is pulped and beaten using a multi-cycle bin for 4 cycles of beating. In order to ensure the evenness of the paper; Adjust the slurry inlet concentration, control the heating temperature and the gap between the heat dispersion grinding discs;

[0046] S2. Adding and stirring: feeding and stirring in the mixer, put the fully pulped and beaten pulp into the mixer, then add functional additives and stir fully, then add the slurry into the original pulp drain tube, the pulp and functional additives The investment ratio is 100:10;

[0047] S3. Straighten out: transport the slurry in the raw pulp leaking barrel to the fourdrinier multi-cylinder paper machine through the straighten out device for papermaking;

[0048] S4. Paper making: use fourdrinier multi-cylinder paper machine for production, and use calender for finishi...

Embodiment 3

[0059] A paper production process, specifically comprising the following steps:

[0060] S1. Beating: the waste paper is continuously beaten, and the waste paper is pulped and beaten using a multi-cycle bin for three cycles of beating. In order to ensure the uniformity of the paper; the beating of the waste paper tends to be divided into filaments, Adjust the slurry inlet concentration, control the heating temperature and the gap between the heat dispersion grinding discs;

[0061] S2. Adding and stirring: feeding and stirring in the mixer, put the fully pulped and beaten pulp into the mixer, then add functional additives and stir fully, then add the slurry into the original pulp drain tube, the pulp and functional additives The input ratio is 100:8;

[0062] S3. Straighten out: transport the slurry in the raw pulp leaking barrel to the fourdrinier multi-cylinder paper machine through the straighten out device for papermaking;

[0063] S4. Paper making: use fourdrinier multi...

Abstract

The invention discloses a paper production process. The paper production process comprises the steps of pulping, charging and stirring, straightening, papermaking, dewatering, irregular pulp sprayingand drying. The process can be used to prepare paper with excellent performance, wherein effects of two sides of the paper are ensured to be basically not different; fibers in original pulp are ensured to be output after passing through a straightening mechanism, and a situation of disorder in a conventional technology is avoided, so that drying quality of the paper is improved. Through irregularspraying, every piece of paper is unique; paper breaking is avoided; finished paper is ensured to have high tensile strength; and enough tension is ensured in a paper making process.

Description

technical field [0001] The invention relates to the technical field of paper production, in particular to a paper production process. Background technique [0002] Paper production is divided into two basic processes: pulping and papermaking. Pulping is to use mechanical methods, chemical methods or a combination of both to dissociate plant fiber raw materials into natural pulp or bleached pulp. Papermaking is the process of combining pulp fibers suspended in water into paper sheets that meet various requirements. [0003] The traditional paper production process has the following disadvantages: there is no mechanism to straighten the raw pulp during the output of the raw pulp, resulting in messy paper textures when the paper comes out at the end; large differences in the effects of the two sides of the paper; poor drying quality ;Paper tension is poor, prone to paper breaks. Contents of the invention [0004] The object of the present invention is to propose a paper pr...
