Problems solved by technology

However, with the increase in demand, the market price of waste paper has risen from 600 to 800 yuan / ton to the current 1,400 to 1,500 yuan / ton. Using waste paper alone requires 1.2 to 1.3 tons to produce a ton of products, and the raw material price of a ton of products has already It reaches 1600-2000 yuan, and the production cost is 2350-2750 yuan / ton, while the current domestic market price of ordinary corrugated paper and bobbin paper is only 2000-2300 yuan / ton. Therefore, most manufacturers can only add a large amount of corrugated paper to reduce costs. Stone powder and other low-quality fillers produce poor-quality and low-grade products, making it difficult for ordinary corrugated paper and bobbin paper to move forward.

Embodiment 1

[0029] Screen and remove impurities from the cassava dregs, remove cassava skin, protein, and other impurities in the cassava dregs, dilute it to a concentration of about 5 to 15%, remove sand through the desander, remove the remaining heavy impurities, and then grind The pulp machine is circularly ground and pulverized until the fiber length is between 0.5 and 1.5 mm, so that fibers of different lengths are separated to form more space frames when the product is formed. The ground cassava dregs are washed and then dehydrated, and the water content is controlled between 70% and 80% for later use.

[0030] Take 700kg of pre-treated cassava residue and 300kg of waste paper pulp and mix them uniformly at a ratio of 7:3, add water to dilute to a concentration of 1-1.5%, add 10kg of adhesive polyacrylamide, 5kg of waterproofing agent AKD, and reinforcing agent PVA in sequence 5kg of polyvinyl alcohol, 15kg of antifungal agent, and 30kg of stone powder are mixed and stirred evenly, ...

Embodiment 2

[0032] The pretreatment process of sprinkling bad slag is the same as Example 1.

[0033] Mix 600kg distiller's grain residue and 400kg waste paper pulp in a ratio of 6:4, add water to dilute to a concentration of 1.5-2.0%, add adhesive polyacrylamide 30kg, waterproofing agent AKD 20kg, stir well, add water to dilute to 0.7-0.8 %, on the machine to produce corrugated paper. According to the requirements of different products, the quantitative range is 90 g / m2 to 250 g / m2. The products have the advantages of toughness, softness, folding resistance, waterproof, cushioning, and shock resistance.

Embodiment 3

[0035] Mix distiller's grains and cassava residues, after pretreatment, take 500kg of mixed residues and 500kg of waste paper pulp and mix evenly at a ratio of 5:5, add water to dilute to a concentration of 1.5-2.0%, add 20kg of polyacrylamide, 10kg of waterproofing agent AKD and stir well Finally, add water to dilute to 0.7-0.8%, and put it on the machine to produce corrugated paper. According to the requirements of different products, the quantitative range is 90 g / m2 to 250 g / m2. The products have the advantages of toughness, softness, folding resistance, waterproof, cushioning, and shock resistance.

[0036] Expected effects and application prospects

[0037] (1) Production cost estimation: Calculated on the basis of 70% cassava dregs or distiller’s grains to produce corrugated paper and bobbin paper, the cost of raw materials will be reduced from 1600 yuan / ton to 1000 yuan / ton (excluding tax, the same below), and the production cost will be reduced by 33 %; It is estimat...

Abstract

The invention discloses a method for producing corrugated paper and bobbin paper by manioc waste and lees. The manioc waste and the lees are purified, ground, washed, and dehydrated respectively; impurities are removed; plant fiber is retained; the mixture of treated manioc waste and lees is mixed with waste paper stock according to the proportion of 1-7 to 3-9; and a paper-making additive is properly added to produce the corrugated paper and the bobbin paper. The method fully utilizes production wastes, namely the manioc waste and the lees to produce good and cheap corrugated paper and bobbin paper. The methd has the advantages of adequate production raw materials, low cost, simple and convenient operation, good product stability, large market potential, and high product profit, prolongs industrial chains of the manioc waste and the lees, solves the waste utilization problem of the prior manioc waste and lees, also reduces the environmental protection pressure of enterprises, improves the economical benefit of the enterprises, drives surrounding villages to be commonly prosperous, and has good social benefit and environmental protection benefit.

Description

technical field [0001] The invention relates to a production method of corrugated paper and bobbin paper. Especially the method of producing corrugated paper and bobbin paper with cassava dregs and distiller's dregs. Background technique [0002] Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling of waste paper is conducive to protecting the environment, protecting forests and saving resources. In the 1970s, the utilization and treatment of waste paper in our country was used for making or compounding toilet paper and low-grade foil paperboard through simple cooking, dispersing, beating, and washing. By the 1980s, the recovery rate of waste paper had reached 25%. Around the same time, a small number of manufacturers can also produce deinked pulp. After the 1990s, some large and medium-sized papermaking enterprises successively introduced equipment and technologies including...
