Embodiment 1

[0024] The single-facer is a mechanical device that presses corrugated paper into corrugated corrugated paper, coats the top with an adhesive, makes it directly bonded to the face paper, and heats it to gel instantly to produce a single-faced corrugated board that meets the quality requirements. The equipment is mainly composed of raw paper frame, corrugated roller, pressure roller, preheating roller, glue application system, glue storage and circulation system, heating system, pneumatic components, and cutting part.

[0025] 1. Raw paper holder, the original paper holder used by single-sided machine is relatively simple, mainly because the machine lifts and manually adjusts the tension of the roll paper, and has a certain bearing capacity, also known as a shaft support.

[0026] 2. Corrugating rollers, the upper and lower corrugating rollers are combined to press the corrugated base paper into corrugated corrugated paper. The matching pressure gap, parallelism and proper midd...

Embodiment 2

[0046] A kind of production technology of corrugated cardboard, this technology is according to embodiment 1, is made of face paper, inner paper, core paper and corrugated paper processed into corrugated corrugated by this adhesive, every production 1000kg of this adhesive needs the following weight Raw materials: 790kg of water, 183.3kg of starch, 8kg of caustic soda, 4kg of borax, 10kg of bridging agent, 2.5kg of stabilizer, 0.5kg of polyether modified silicone, 0.4kg of wood fiber, 0.1kg of cellulose ether, plant insect repellent powder 1kg (among them, 0.3kg camphor powder, 0.4kg prickly ash powder, 0.2kg peppermint powder, 0.1kg peppermint powder) and 0.2kg cis-cypermethrin.

[0047] The production technology of above-mentioned adhesive comprises following production steps:

[0048] (1) Add 760kg of water to the barrel, and then heat it to 40°C with steam;

[0049] (2) Add 2kg of caustic soda and keep stirring until completely dissolved;

[0050] (3) Add 183.3kg of star...

Embodiment 3

[0055] A kind of production technology of corrugated cardboard, this technology is according to embodiment 1, is made of face paper, inner paper, core paper and corrugated paper processed into corrugated corrugated by this adhesive, every production 1000kg of this adhesive needs the following weight Raw materials: 780kg of water, 200kg of starch, 6kg of caustic soda, 3kg of borax, 9kg of bridging agent, 1.5kg of stabilizer, 0.1kg of polyether modified silicone, 0.1kg of wood fiber, 0.07kg of cellulose ether, and 0.5 kg of plant repellent powder kg (of which, 0.2kg of camphor powder, 0.2kg of Zanthoxylum bungeanum powder, 0.08kg of incense powder, and 0.02kg of peppermint powder) and 0.2kg of cis-cypermethrin.

[0056] The production technology of above-mentioned adhesive comprises following production steps:

[0057] (1) Add 755kg of water to the barrel, and then heat it to 39°C with steam;

[0058] (2) Add 3kg of caustic soda and keep stirring until completely dissolved;

Abstract

The invention discloses a production technology for a corrugated paperboard. The corrugated paperboard is made of face paper, inner paper, core paper and corrugated paper machined into waveform corrugations through binding agents. The following raw materials including, by weight, 760 kg-790 kg of water, 183 kg-222 kg of starch, 5 kg-8 kg of caustic soda flakes, 3 kg-4 kg of borax, 8 kg-10 kg of a bridging agent, 1.2 kg-2.5 kg of a stabilizing agent, 0 kg-0.8 kg of a defoaming agent, 0.1 kg-0.5 kg of a waterproof additive and 0.2 kg-1.2 kg of an insecticide mixing agent are needed by producing 1000 kg of binding agents each time. The waterproof additive includes cellulose ether and wood fiber, and the insecticide mixing agent comprises plant insecticide powder and mild cypermethrin. By means of a corrugated carton made through the production technology, glue failure is not likely to happen even in a high-humidity and multi-insect environment, the product is free of toxins and explosion, the combustion risk is avoided, the production technology is simple, no three-waste emission exists during production, the environment-friendly requirement is met, and the production technology is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process of corrugated cardboard. Background technique [0002] Corrugated boxes are rigid paper containers made of corrugated cardboard through die-cutting, creasing, nailing or glueing. Corrugated cardboard is made by bonding face paper, inner paper, core paper and corrugated paper processed into corrugated corrugated. The flute shapes of corrugated corrugated paper include V shape, U shape and UV shape. The characteristic of V-shaped corrugated waveform is that the plane has high anti-pressure value, which saves the amount of adhesive and corrugated base paper during use; the characteristic of U-shaped corrugated waveform is that it has a large glue area, firm bonding, and a certain degree of elasticity. It is not as fragile as V-shaped flute, but the plane expansion pressure strength is not as good as that of V-shaped flute; UV-shaped corrugated roll combine...
