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] The cassava residue is screened and impurity removed, cassava peel, protein, and other impurities are removed from the cassava residue, diluted to a concentration of about 5 to 15%, and sand is removed by a de-sander to remove the remaining heavy impurities. In the pulping machine, it is circulated to grind and pulverize until the fiber length is between 0.5 and 1.5 mm, so that fibers of different lengths can be separated, so as to form more space structures when the product is formed. The ground cassava residue is washed and dehydrated, and the moisture 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 evenly at a ratio of 7:3, dilute with water to a concentration of 1 to 1.5%, and add 10kg of adhesive polyacrylamide, 5kg of waterproofing agent, and PVA in turn After mixing 5kg of polyvinyl alcohol, 15kg of antifungal agent, and 30kg of stone powder, add water to dilute to...

Embodiment 2

[0032] The pre-treatment process of sprinkling dregs is the same as in Example 1.

[0033] After mixing 600kg of vinasse and 400kg of waste paper pulp in a ratio of 6:4, add water to dilute to a concentration of 1.5-2.0%, add 30kg of adhesive polyacrylamide and 20kg of waterproofing agent AKD, stir evenly, 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 product has the advantages of toughness, softness, folding resistance, waterproof, cushioning, and shockproof.

Embodiment 3

[0035] Mix the distiller's lees with the cassava residue, after pre-treatment, take 500kg of the mixed residue and 500kg of waste paper pulp and mix them evenly in a ratio of 5:5, dilute with water to a concentration of 1.5-2.0%, add 20kg of polyacrylamide, 10kg of waterproofing agent, and stir well After that, add water to dilute to 0.7-0.8%, and produce corrugated paper on the machine. According to the requirements of different products, the quantitative range is 90 g / m² to 250 g / m². The product has the advantages of toughness, softness, folding resistance, waterproof, cushioning, and shockproof.

[0036] Expected effects and application prospects of results

[0037] (1) Production cost estimation: If the cost of raw materials is reduced from 1600 yuan / ton to 1000 yuan / ton (excluding tax price, the same below), the production cost will be reduced by 33 %; The cost of the product is expected to be reduced from RMB 2,600 / ton to RMB 1,750 / ton. Based on the annual production of 30,...

Abstract

The invention discloses a cassava dregs distiller's dregs and a method for producing corrugated paper and bobbin paper. The cassava dregs and distiller's dregs are respectively purified, ground, cleaned, dehydrated, impurities are removed, and plant fibers are retained. 7:3-9 ratio mixing, appropriate amount of paper-making additives are added to produce corrugated paper and bobbin paper. The present invention makes full use of production wastes—cassava dregs and vinasse dregs to produce high-quality and cheap corrugated paper and bobbin paper. The production raw materials are sufficient, the cost is low, the operation is simple, the product is stable, the market potential is large, and the product profit is high. It extends the industrial chain of cassava dregs and distiller's grains, solves the current utilization problems of cassava dregs and distiller's grains, reduces the environmental protection pressure of enterprises, improves the economic benefits of enterprises, drives the common prosperity of surrounding rural areas, and has good social and environmental benefits.

Description

Technical field [0001] The invention relates to a production method of corrugated paper and yarn tube paper. Especially the method for producing corrugated paper and yarn tube paper with cassava residue and vinasse residue. 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. The utilization and treatment of waste paper in my country in the 1970s was through simple cooking, decomposing, beating and washing, and then used to make or mix toilet paper and low-grade foil and cardboard. By the 1980s, the recovery rate of waste paper reached 25%. Around, a few manufacturers can also produce deinked pulp. After the 1990s, some large and medium-sized paper companies introduced equipment and technology including production lines from abroad, and carried out tar...
