Bamboo pulp is a kind of paper pulp made of bamboo, mainly with bamboo, bamboo, bamboo and other bamboo as raw materials, has many unique characteristics and advantages, is widely used in various fields. The following is a detailed introduction of the production process, characteristics, advantages and applications of bamboo pulp.
一、 Production process of bamboo pulp:
Often used by the sulfate method and caustic soda method are made. There are also the tender bamboo through the green, pickled with lime into half clinker. Fibre form and length, somewhere between wood and grass fiber. Easy to apply glue, bamboo pulp for medium fiber length pulp, fine and soft. Spine thickness, high tear degree, low breaking resistance strength and tensile strength. Have a higher mechanical strength.
1. Bamboo selection: more than 3 years of bamboo, bamboo, bamboo.
2. Bamboo cutting: cut the bamboo into 2-3 cm bamboo slices
3. Bamboo crushing and washing: use a crusher to break the bamboo materials into small pieces and clean them repeatedly with clean water
4. Bamboo cooking: put the bamboo into the boiler, at high temperature and high pressure, add chemical accessories to cook, to remove the lignin and other impurities in the bamboo
5. Bleaching of bamboo: Bleach the boiled bamboo to improve the whiteness of the pulp
6. Bamboo pulping: mix the bleached bamboo with the appropriate amount of water, stir through the mixing equipment, make the bamboo fiber and water separation.
二、 Characteristics of bamboo pulp
Bamboo fiber has two kinds of cell wall structures, one is multi-layer structure, the fiber wall is composed of wide layer and narrow layer, wide layer and narrow layer are about 4 ~5 layers, the wide layer of the color is lighter, indicating that the element density is low and the narrow layer is deeper. That is, lignin density is high, and this type of fiber is mainly found in the peripheral parts of the vascular bundle, accounting for about 1 / 2 of the total fiber number. The other type of fiber cell wall is very thick and narrow. The inner layer of the fiber secondary wall is mainly composed of two wide layers, and the outer wide layer is much wider than the inner wide layer.
1. Bamboo pulp fiber is long and thin, moderate softness, will not stimulate the skin, suitable for people with sensitive skin
2. Bamboo pulp toilet paper is more breathable and more comfortable than wood pulp toilet paper
3. Bamboo fiber can be pure spinning, can also be mixed with cotton, silk, hemp and synthetic fiber mixing or interwoven, can be widely used in the production of textiles
三、The advantage of bamboo pulp
1. Bamboo grows fast and can produce bamboo pulp in large quantities in a short time, so it is more efficient than wood pulp
2. The growth of bamboo has little impact on the environment, while bamboo has a long life and can be recycled, which is conducive to environmental protection
3. Bamboo pulp fiber has many incomparable advantages, such as good spinnability, colorability, natural antibacterial health function and moisture absorption and humidity release at the top of the fiber
四、Application of bamboo pulp
1. In the field of textile industry, bamboo fiber can be pure spinning or blended with other fibers or interwoven, used for the production of various underwear, towels, mat and other textiles
2. In the field of paper making, bamboo pulp can produce a variety of toilet paper, paper-plastic products, packaging paper, cable paper, insulating paper, cement bag paper, etc
3. In the field of construction, bamboo pulp can be made into various specifications of plate, wallpaper and other building materials, with environmental protection, beautiful and other characteristics
4. In the field of stationery, bamboo pulp can be made into various colors of pen sticks, pen strings and other stationery
In short, bamboo pulp, as a new type of green environmental protection fiber material, has broad application prospects and market prospects. With people's increasing attention to environmental protection and health, bamboo pulp products will receive more and more attention and favor.
abstract:
Bamboo pulp and paper products and natural bamboo pulp and paper products have good development prospects, so we need to continue to improve and optimize in raw material cultivation, production process, environmental protection cost and other aspects, and maintain the overweight rating of light industry-paper industry and paper packaging sub-industry. With the improvement of consumers' living standards, the market demand for strong and soft products is increasing. The environmental protection concept of natural bamboo and wood household paper and the original ecological fiber color are favored by the new generation of consumers. From the point of view of raw material characteristics, bamboo pulp safety, comfort, environmental protection and scarcity four advantages, bamboo to wood is the most suitable for pulp and paper raw materials, but in bamboo cultivation, production equipment and skills, environmental treatment costs still has defects, need to continue optimization improvement to promote the further development of the industry.
Bamboo pulp is of Chinese characteristics, and bamboo pulp has many advantages such as rich raw material resources and short growth cycle, especially reducing the cutting of wood and protecting forest resources. Although the production capacity of bamboo pulp is small, it is one of the most important supplementary raw materials for paper making. In recent years, the growth rate of output value of Chinese bamboo industry has recovered, but the proportion of output value is still relatively low, and the industrial space is still to be explored.
Bamboo pulp and paper making has unique advantages, raw materials, technology, environmental protection and other cost factors limit the development of the industry. Bamboo pulp has the unique advantages of safety, comfort, environmental protection and scarcity, and bamboo is the most suitable raw material for pulp and paper making, second only to wood. Bamboo pulp covers a wide range of paper products, but facing the dilemma of "wide surface and low quantity", in recent years, the proportion of bamboo pulp and paper has increased, the penetration rate still has a large space for expansion, the production capacity and operating rate of bamboo pulp are relatively low, and the industrial development is slightly inferior. In recent years, the popularity of natural life paper has brought new attention and development opportunities to the bamboo pulp market. However, with the development of raw materials, technology, environmental protection and other cost factors in bamboo pulp and paper, the future industry still needs to promote the reasonable expansion of the industry with linding pulp, and improve the equipment and process to reduce the production cost.
Industry leaders have been layout bamboo pulp paper industry, household paper, environmental protection packaging paper dominated. In addition to the traditional bamboo pulp and paper enterprises, in recent years, many leading enterprises in the paper and packaging industry have successively arranged bamboo pulp business as a supplement to wood pulp raw materials and expand the demand direction of new products. Among them, bamboo pulp household paper products are the most common. Compared with wood pulp household paper, bamboo pulp paper has stronger toughness. By strengthening the advantages of bamboo fiber and marketing strategy differentiation, various brands cultivate market cognition and consumer recognition. In terms of bamboo pulp packaging paper, China's new plastic ban was issued, and the alternative demand space for paper packaging was expanded. Environmental-friendly bamboo pulp and paper plastic can be widely used in many downstream industries, with great development potential.
Bamboo is a high quality fiber raw material, China is also the first country to use bamboo pulp and paper. Bamboo in fresh bamboo is also a traditional Chinese medicinal material, its medicinal value, as early as in "Compendium of Materia Medica" recorded, fresh bamboo, it has a sweet smell, non-toxic, the main stroke, wind, chest blood, stop boredom, thirst and other effects, contained in the first volume of "Chinese medicine" (1992). With the development of modern science and technology, after continuous exploration, fresh bamboo drain has been widely used in food (beverage), health care products, drugs and other aspects. China is rich in bamboo resources, and there are many existing methods of making bamboo raw fiber, pulping and extraction of bamboo drain. However, these existing technologies have problems such as low bamboo utilization rate, high industrial production cost and difficulty in pollution control.
