What is bamboo pulp paper?
Bamboo pulp paper is a kind of paper made from bamboo as raw material.
This paper has a natural color and texture. It is produced through papermaking processes such as cooking and rinsing, and can use bamboo pulp alone, or have a reasonable ratio with wood pulp and grass pulp. Bamboo pulp paper can be divided into different types, such as half pulp, whole pulp and straw pulp paper. This paper uses a pure physical pulping method, does not contain any chemical composition, so it has the characteristics of environmental protection. In addition, its price is usually higher, but it has strong water absorption, soft paper, uniform thickness, no holes, uniform wrinkling, consistent color, and no impurities. Moreover, due to the characteristics of bamboo fiber, this kind of paper also has the advantages of good air permeability, no bleach and phosphor.
Production process of bamboo pulp paper
Bamboo collection and processing
Bamboo is the main raw material of bamboo pulp paper, according to the different varieties of bamboo and tree age, the collection of parts are also different, the current market mainly used is bamboo roots and stems , picking should pay attention to the roots and stems and do not bring too much soil and weeds, affecting the subsequent processing, at the same time should be environmentally friendly picking process, to avoid pollution to the environment.
Pulping process
Alkaline pulping
Alkali pulping is a commonly used method for preparing bamboo pulp. Its process includes lye leaching, beating, screening, washing and so on. When making lye, we should pay attention to controlling temperature and concentration to prevent burning, explosion and other situations. In the pulping process, the selection and commissioning of the beater should meet the process requirements to avoid affecting the process and pulp quality.
acid pulping
Acid pulping is suitable for high temperature and high humidity areas, and its process mainly includes acid leaching, beating, screening and other steps. Attention should be paid to the control of acidity during operation to ensure good pulping color.
Papermaking process
slurry preparation and ratio
Before pa making, bamboo pulp should be prepared and mixed according to a certain proportion to achieve the ideal paper quality. At the same time, the humidity and viscosity of the slurry should be taken into account, which has a greater impact on the quality of the paper.
Modeling
Modeling refers to the conversion of the slurry into a certain shape, size and thickness of the paper, in the modeling should be first to screen the slurry filtration, draining and other operations. Paper thickness, quality and other factors are affected by drying and calendering, in the operation process should pay attention to the adjustment of drying temperature, drying speed, pressure and other parameters, in order to avoid excessive drying, insufficient pressure and other problems.
Conclusion
<p>Bamboo pulp papermaking is an environmentally friendly and energy-saving paper production method. Attention should be paid to pollution control and paper quality improvement in the production process. The above is the main production process of bamboo pulp paper, each link has the corresponding precautions and technical requirements.
Which is the bamboo pulp paper and wood pulp paper better?
Both kind of papers have their advantages and disadvantages respectively, and which one is better depends on the specific use needs and preferences.
Also , the two kinds of papers are different in environmental protection, quality, scope of application, price and so on. Here are the details:
Environmental protection.
<p>Bamboo pulp paper production process does not need to use chemical agents, the impact on the environment is small, the original wood pulp paper production process has a certain impact on the environment, because the need to cut down natural forests.
<h3>Quality<p><p>Bamboo pulp paper fiber length is short, fiber thickness is not uniform, so its strength and durability is poor. Wood pulp paper fiber length is longer, fiber thickness is uniform, so its strength and durability is better.
Scope of application
<p>Bamboo pulp paper is suitable for some products with low quality requirements, such as toilet paper, napkins, etc. And wood pulp paper is suitable for products with high quality requirements, such as books, magazines, packaging boxes, etc.
Price
The price of bamboo paper is relatively low, which can reduce manufacturing costs and improve product competitiveness. The price of wood pulp paper is relatively high, the manufacturing cost is high, and the product competitiveness is weak.
In addition, the use of the two kinds paper is also different. The use of bamboo pulp paper is mainly to manufacture paper, cardboard, paper towels and other low-grade products. The use of wood pulp paper is mainly to manufacture high-grade paper, books, magazines and other high-quality products.
Characteristics and applications of bamboo pulp paper for printing
Characteristics
Bamboo pulp paper is an environmentally friendly paper material . Paper made from bamboo has many advantages over paper made from trees.
First, bamboo is a fast growing plant that can mature in 3-5 years. Therefore, using bamboo to make paper can be produced more quickly than trees, making the production process more efficient.
Secondly, bamboo is rich in cellulose, which makes the paper made of bamboo pulp have high strength and durability. In addition, this kind of paper has better mechanical properties and better whiteness effect.
Application of bamboo pulp paper
Publication and printing
Bamboo pulp papers can be used to print various books and magazines. They have high whiteness and smoothness, which can ensure print quality and visual effects. In addition,they can print various types of text and images, and has a high degree of color reproduction.
Commercial printing
Printing paper made of bamboo pulp paper can be used to make posters, business cards, marketing brochures and other commercial purposes. The paper has fine texture and smoothness, making it ideal for printing high definition images and text.
Packaging and printing
<p>Bamboo pulp paper can be used to manufacture various types of packaging materials, such as packaging boxes, food packaging, household packaging, etc. The material properties of this kind of paper make it waterproof, moisture-proof and oil-proof, which can protect the product and maintain the appearance of the product.
Media printing
The paper can be used for the printing of media magazines, times and news newspapers. It provides high-quality print quality, so you can achieve a clearer reading experience with images and clearer text.
The future of bamboo pulp paper
With the continuous improvement of environmental awareness, bamboo paper as an environmentally friendly packaging material. And its application field is also expanding. In the future, this kind of paper will be applied in a wider range of fields. At the same time, its production technology will be continuously improved and improved to provide higher quality paper materials.</p>
Conclusion
In general, bamboo pulp paper, as an environmentally friendly, high-quality paper packaging material, has been widely used in the field of printing. From the natural properties of bamboo to the production process of paper, the paper has unique advantages in environmental protection, economy and production performance. In the future, with the continuous improvement of environmental awareness and the continuous development of science and technology, the application field of bamboo paper will continue to expand and deepen.
