Problems solved by technology

However, with the continuous expansion of production capacity, the problems exposed are becoming more and more serious: 1. Environmental pollution is overwhelming
Due to the workshop-style production, the pulp used is directly made into paper without being washed, causing the COD of papermaking wastewater to exceed the standard, generally around 10,000mg / l. Although this kind of water can be partially reused after simple treatment, most of it is still high COD papermaking wastewater must be discharged outside, causing water pollution in river basins
2. Product quality varies
Especially the bulk, in order to achieve the required bulk and feel, some use the method of adding wood chips, but this will affect the combustion effect of the product, resulting in insufficient combustion, black smoke, grayish white, and heavy smell
Will affect the environmental protection and health of sacrificial activities

Embodiment 1

[0019] (1) Use high-yield uncolored bamboo pulp as raw material, with a yield of 90%;

[0020] (2) Dispersing the slurry in step (1) to obtain dispersed pulp;

[0021] (3) Beating: The pulp after deflaking is beaten by three double disc mills connected in series with light knives, the beating concentration is 3.5%, and the beating degree is 14 O SR, wet weight 13 grams.

[0022] (4) Ingredients: ingredient concentration 3%, resin control agent 1kg / t slurry, fungicide 0.3kg / t slurry.

[0023] (5) Copying: Copying into a quantitative 30g / m on a rotary screen low-speed paper machine 2 bamboo pulp sacrificial paper.

[0024] (6) Water treatment: part of the white water produced in the paper machine papermaking process is recycled, and part of it is treated in the same flow and then discharged into the middle section for further biochemical treatment, finally achieving clean production.

Abstract

The invention discloses a method for producing high-yield natural color bamboo pulp paper for fete. The method comprises the following steps of slurry selection, defibering, beating, material preparation and manufacture of paper with pulp. According to the preparation method, the obtained product has the advantages of pure natural color, good strength, high bulk, quick burning, grayish white and no odor. The production process is fully industrialized and can fully achieve clean production, and environmental and social benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of pulping and papermaking, in particular to a method for producing high-yield uncolored bamboo pulp sacrificial paper. Background technique [0002] For thousands of years in China, there has been a custom called burning paper. The paper burned is an important item used by people in sacrificial activities. It is also called money paper. paper etc. For thousands of years, its production method has been made by folk soil method, which is to soak bamboo and lime naturally for a certain period of time, then take it out and smash it into pulp, and finally copy it into paper. Papermaking technology is a process of continuous evolution, from the initial manual scoop forming and drying, to the later machine forming and air drying, and now it has evolved to the use of cylinder forming and drying cylinder drying, and the production efficiency has been greatly improved. However, with the continuous expansion of prod...
