Embodiment 1

[0027] (1) Dehydration of coconut bran: place coconut bran in a 55-65°C oven for constant temperature dehydration, so that the water content of coconut bran is reduced to below 3wt%, and make 80-mesh coconut bran powder through a pulverizer;

[0028] (2) Pulping: the waste paper is made into 100-mesh waste paper powder through a pulverizer, and then 10kg of waste paper powder is added to the beater, and water is injected into the beater, and a uniform pulp is made through sufficient beating, and then 2kg of coconut bran is added Flour and 0.1kg sweet potato starch, continue beating to obtain a uniform slurry, the gained slurry is added in the refiner, the unbroken slurry is ground through the refiner, and finally the slag is removed by the slag remover;

[0029] (3) Dehydration: pump the prepared slurry to the wire section for forming and dehydration until the dryness reaches 15-25%, and the formed slurry is transported to the press section for dehydration until the dryness rea...

Embodiment 2

[0033] (1) Dehydration of coconut bran: place coconut bran in a 55-65°C oven for constant temperature dehydration, so that the water content of coconut bran is reduced to below 3wt%, and make 80-mesh coconut bran powder through a pulverizer;

[0034] (2) Pulping: the waste paper is made into 100-mesh waste paper powder through a pulverizer, and then 15kg of waste paper powder is added to the beater, and water is injected into the beater, and a uniform pulp is made by sufficient beating, and then 3kg of coconut bran is added Flour and 0.2kg sweet potato starch, continue beating to obtain a uniform slurry, the gained slurry is added in the refiner, the unbroken slurry is ground through the refiner, and finally the slag is removed through the slag remover;

[0035] (3) Dehydration: pump the prepared slurry to the wire section for forming and dehydration until the dryness reaches 15-25%, and the formed slurry is transported to the press section for dehydration until the dryness rea...

Embodiment 3

[0039] (1) Dehydration of coconut bran: place coconut bran in a 55-65°C oven for constant temperature dehydration, so that the water content of coconut bran is reduced to below 3wt%, and make 80-mesh coconut bran powder through a pulverizer;

[0040] (2) Pulping: the waste paper is made into 100-mesh waste paper powder through a pulverizer, and then 15kg of waste paper powder is added to the beater, and water is injected into the beater, and a uniform pulp is made by sufficient beating, and then 3kg of modified pulp is added. Coconut bran powder and 0.2kg sweet potato starch, continue beating to obtain a uniform slurry, the gained slurry is added in the refiner, the unbroken slurry is ground through the refiner, and finally the slag is removed through the slag remover;

[0041] (3) Dehydration: pump the prepared slurry to the wire section for forming and dehydration until the dryness reaches 15-25%, and the formed slurry is transported to the press section for dehydration until...

Abstract

The invention discloses a process for processing corrugated paper by utilizing waste paper and coconut bran, and relates to the technical field of processing of the corrugated paper. The process comprises the following steps: (1) coconut bran dehydration; (2) pulping; (3) dehydration; and (4) drying. According to the invention, with coconut bran powder as a main auxiliary material, the usage amount of the waste paper for processing of the corrugated paper is reduced, and a novel application of the coconut bran in the field of processing of the corrugated paper is realized, so the coconut branis no longer limited to be a gardening medium in application fields; meanwhile, through two steps of pulping operation, a uniform pulp used for processing of the corrugated paper is prepared by utilizing waste paper powder, the coconut bran powder and plant starch, and the corrugated paper is prepared through subsequent conventional operations, so the prepared corrugated paper has packaging properties comparable to the packaging properties of conventional corrugated paper in the prior art, and can be extensively applied to packaging of a variety of products.

Description

Technical field: [0001] The invention relates to the technical field of corrugated paper processing, in particular to a process for processing corrugated paper with waste paper and coconut chaff. Background technique: [0002] As an excellent packaging material, corrugated carton has the advantages of light weight, puncture resistance, shock resistance, easy processing and molding, good adaptability to decoration and printing, can be recycled, and has no pollution to the environment. Favored by modern society. The scope of use is getting wider and wider, and the speed of development is getting faster and faster. At present, corrugated paper is mostly made of waste paper, realizing the reasonable reuse of waste paper, but waste paper resources are still limited, and it is impossible to fundamentally reduce the consumption of wood. [0003] Coconut peat is coconut husk fiber powder, a by-product or waste of coconut after processing, and a pure natural organic medium that fal...
