Embodiment 1

[0035] A workshop metos DCT135+ paper machine makes 36g / m 2 and 43g / m 2 Process parameters and physical property data of paper towels:

[0036]

[0037]

[0038] The physical properties of the base paper are all within the standard requirements of the formula card. At the same time, the production is stable and there are no phenomena such as large fluctuations in the moisture content of the base paper, wet paper sheets not being loaded into the vat, and poor forming.

Embodiment 2

[0040] An environment-friendly high-grammage paper towel production process adopts the following steps:

[0041] (1) pulp preparation process:

[0042] (1-1) Carry out pulping treatment to the commercially available rainbow fish slurry, and the pulping concentration obtained is 6wt%;

[0043] (1-2) Put the pulp after the pulping treatment in a refiner for refining treatment, use a long fiber refiner and a refiner for two refining, and control the concentration of the pulp in the long fiber refiner It is 4.8wt%, the slurry flow return rate is 15%, the knocking degree is 20SR, the power of the long fiber refiner is 90kwh / t, the control slurry concentration in the refiner is 3.5wt%, the slurry flow return rate is 8%, the beating degree is 28SR, and the power of the refiner is 35kwh / t;

[0044] (1-3) Add broken paper to the long-fiber pulp obtained after the refining treatment, the absolute-dry dosage ratio of the long-fiber pulp is 45wt%, and the absolute-dry dosage ratio of th...

Embodiment 3

[0052] An environment-friendly high-grammage paper towel production process adopts the following steps:

[0053] (1) pulp preparation process:

[0054] (1-1) The commercially available Marlboro slurry is crushed, and 14wt% of the leaflet slurry and 15wt% of the crystal slurry are added to obtain a pulp concentration of 6wt%;

[0055] (1-2) Put the pulp after the pulping treatment in a refiner for refining treatment, use a long fiber refiner and a refiner for two refining, and control the concentration of the pulp in the long fiber refiner It is 4.9wt%, and the slurry flow return rate is 18%, and the beating degree is 22SR. 10%, the beating degree is 30SR, and the power of the refiner is 40kwh / t;

[0056] (1-3) Add broken paper to the long-fiber pulp obtained after the refining treatment, the dry-dry dosage ratio of the long-fiber pulp is 50wt%, and the concentration of the added broken paper dry-dry dosage ratio in the pulp It is 20wt%, the preparation obtains slurry;

Abstract

The invention relates to an environment-friendly high-gram weight paper towel production process. The high-gram weight paper towel is prepared through two steps of a pulp preparation process and a papermaking process. The pulp preparation process includes pulping and refining long-fiber pulp. Treatment, adding broke paper to the long-fiber pulp obtained after refining treatment, and preparing the pulp; the papermaking process includes transporting the pulp stored in the pulping tank to the headbox through the pulping pump, and the pulp enters between the screen blankets After dehydration, a wet paper web is formed, passed through the felt, enters the press section for pressing and dehydration, and the paper web exiting the press section is transferred to the drying cylinder and air hood system for drying, and the dried paper web enters the coiling section for coiling, forming Paper rolls are produced to obtain environmentally friendly high-gram weight paper towels. Compared with the prior art, the present invention has the advantages of stable pulp quality, higher operation efficiency, lower wrinkle rate of finished products, and the like.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to an environment-friendly production process for high-grammage paper towels. Background technique [0002] Crescent-shaped high-speed toilet paper machines generally produce at a speed of 1500-2000m / min, and the quantitative range of base paper making is 11--25g / m 2 , its equipment mainly produces high-quality household paper with the characteristics of high speed, high efficiency and high production capacity. High grammage paper towels are generally produced by rotary paper machines or fourdrinier paper machines with narrower width and slower speed due to the characteristics of high base paper weight, high wet strength, and high moisture requirements, such as Chuanzhijiang BF10 series paper machine etc. Crescent-type high-speed paper machines are not suitable for producing high-weight paper towels, but when they must be produced due to production needs, a series of problems such as ex...
