Culture comes from bamboo
When you touch a silky, soft, comfortable and healthy piece of bamboo toilet paper, do you think of its birth process? Now we take out a piece of bamboo toilet paper, smell the elegant bamboo fragrance, and listen to its origin. Good bamboo toilet paper is produced from good raw materials. To understand bamboo toilet paper, we must start with bamboo.
Not all bamboo can be used to make bamboo toilet paper. The most suitable variety for papermaking is Cizhu. Bamboo planting and afforestation is the first step to ensure a continuous supply of raw materials for bamboo pulp and papermaking. compared with planting trees, planting bamboo is relatively easier, because bamboo will "give birth". If you plant a seedling, you can grow a large area of bamboo.The planting process of bamboo includes: seed selection, seed preparation, bamboo planting, cultivation and forest. The growth rate of bamboo is fast, and it only takes 2-3 years from seedling to mature.Bamboo growth process does not apply chemical fertilizer, put an end to chemical and heavy metal residues from the source, there are good raw materials, can make good paper.
Cut bamboo and prepare materials
Bamboo is full of treasures, fresh bamboo shoots are delicious in the world, and mature bamboo has a wide range of uses. The felling of bamboo forest is in the form of thinning, which can be used without destroying the ecological environment. The cut bamboo can be used to process bamboo utensils or to make bamboo toilet paper. Bamboo papermaking is an ancient invention in China. Nowadays, the original pure handmade bamboo paper technology is still preserved in the middle and upper reaches of the Yangtze River in China. When felling, choose 3 years to produce annual bamboo, 2-3 inches from the ground, the knife edge is too low will destroy bamboo whip reproduction and bamboo shoots, too high will waste nutrients. Select tall and slender adult bamboo as raw material for papermaking, remove old bamboo residue for other uses, cut off branches and leaves, bamboo tips, bamboo leaves rot as natural fertilizer. Cut bamboo section, 2 meters into a section, tied into a bundle of 50 kilograms, transported to the material yard. Wash bamboo slices with mountain spring and stream water to remove sediment impurities.Then it is transported to the stacking yard and dried naturally for 3 months to remove excess water and set aside.
wash and screen the slices
Wash the air-dried raw materials with clean water 5 times after unstacking, completely remove sediment, dust, bamboo skin and other impurities, and cut into standard bamboo slices, and then enter into the silo after 6 screening.
Remove lignin and non-fiber components. Feed the bamboo slices from the silo into the presteamer for cooking. Then enter the high-strength screw extruder for strong extrusion and strong pressure.Then cook in a two-stage preevaporator. Then enter the two-stage high-strength screw extruder for strong extrusion and strong pressure. Finally, enter the 20-meter-high vertical steamer for formal high-temperature and high-pressure replacement cooking. Then put it into the pulp tower for heat preservation and cooking.
Six stages of screening and washing will thoroughly remove the non-fiber components of cooking: the first and second stages are coarse sieving and coarse washing, the third and fourth stages are fine sieving and fine washing, and the fifth and sixth stages are fine sieving and fine washing. Finally, delignification and three stages of washing are carried out to ensure that the purity and cleanliness of the fiber meet the requirements of papermaking. All of the above are physical pulping process, bamboo toilet paper is pulped by the whole physical method, the production process has no harm to the human body, and the finished product has no harmful chemical residue, health and safety. Use natural gas instead of traditional fuel to prevent smoke from polluting the air. Remove the bleaching process, retain the original color of plant fibers, reduce production water consumption, avoid the discharge of bleaching sewage, and protect the environment.
Copy the pulp board
The screened natural slurry is sent into the slurry storage tank with slurry pump and pipeline. Decompose the slurry and adjust the concentration to the copying requirements. After entering the front pool, enter the pulp distributor, distribute the pulp evenly in the net part of the 4-meter wide pulp board machine, and distribute the pulp at the speed of 300 meters per minute. After forming, dewatering and stripping, the net part enters the 12-channel pressing process, and then enters 24 groups of dryers to dry, and the moisture content is controlled at about 8%. Then it is sliced into pieces, and the pulp board is cut into corresponding specifications using a slitting machine, which is used for packaging, transportation, sales and use.
Copy the base paperThe pulp board enters the base paper workshop, decomposes with a pulping machine, enters the raw pulp pool, is broken down by 6 high-power disc mills, and then enters the mixing pool after dividing the silk broom. the tapping degree and concentration should meet the requirements of the process standard, and a large roll of base paper can be made.
Cut the package
According to the function and use of the product, the large roll of base paper is cut and packaged into product series of different specifications. Such as reel bamboo toilet paper,extractable bamboo toilet paper.
This is not only the whole process of the birth of bamboo toilet paper, but also the sublimation process of bamboo life value. And choosing to use bamboo toilet paper is also a reflection of people's high values.
