Problems solved by technology

[0003] Corrugated packaging is very common for frozen goods in the market now, and the market demand is growing rapidly. However, frozen packaging has high requirements for the strength and moisture resistance of corrugated base paper. These two quality indicators of corrugated base paper in the market are very unstable at present. Moreover, the sizing method adopted by the manufacturer to improve the strength and moisture resistance of the corrugated base paper has caused the workers high labor intensity, poor working environment, prone to burn accidents, and poor work safety.
[0004] In summary, there are still technical defects in the production process of high-strength corrugated paper, which must be improved in actual production.

Embodiment 1

[0024] Step 1: Pulping:

[0025] Domestic waste paper, including waste books and waste office paper, is pulped, screened, concentrated, and medium-consistency refined to obtain domestic waste paper pulp;

[0026] The second step: base paper processing:

[0027] The pulp obtained in the first step is formed, squeezed and dried to obtain base paper;

[0028] The third step: the preparation of sizing agent:

[0029] 10m with stirring 3 Inject 5.5 tons of water into the dissolving container, add 1 ton of starch into the dissolving container, add 2kg of ammonium persulfate after fully stirring, and send it into the glue tank with a pump. Start the heating device, intelligently control heating and heat preservation parameters: heat to temperature T1, T1=65°C, heat for 20 minutes, then keep warm at this temperature for 10 minutes, continue heating, heat to temperature T2, T2=95°C, heat for 15 minutes, then Keep warm at this temperature for 30 minutes. Heating during cooking, and...

Abstract

The invention belongs to the field of paper manufacturing and particularly relates to a production technology of high-strength corrugating base paper. The production technology of the high-strength corrugating base paper includes the following steps of pulping, base paper processing, sizing agent preparing and sizing. The production technology has the advantages that produced products are stable in quality, strength and damp resistance are ensured, workers do not heavy physical labor in the production process, and high-temperature and high-risk work environments are avoided.

Description

(1) Technical field [0001] The invention belongs to the field of papermaking, in particular to a production process of high-strength corrugated base paper. (2) Background technology [0002] Corrugated packaging is light and strong, which not only protects the goods, but also facilitates transportation and loading and unloading. It is recyclable and is a green and environmentally friendly product. It is widely used in the packaging field. With the wide application of corrugated packaging, various commodities have different quality requirements for corrugated packaging products. As the main raw material of corrugated packaging, the quality stability and pertinence of quality requirements of high-strength corrugated paper have become a challenge for packaging companies and paper-making companies. new challenges. [0003] Corrugated packaging is very common for frozen goods in the market now, and the market demand is growing rapidly. However, frozen packaging has high requirem...
