How to teach students to make green bamboo from paper

You can publish a special edition in the campus nest, it's so talented.

When our homeroom teacher was making Jinghu, he taught us that we should roast the water on the fire now, but it will become bent, and then straighten it with our hands, and then split it.

Yes, but it is much more complicated than wood to make raw materials, the fermentation time is longer, the quality is not as good as that made of wood, and it is not cost-effective.

Another great achievement of bamboo is papermaking. As early as the 9th century, China began to use bamboo to make paper, about 1000 years earlier than Europe. Regarding the use of bamboo to make paper, the Ming Dynasty "Tiangong Kaiwu" made a detailed record, and attached bamboo paper manufacturing drawings.

Steps: Materials to be prepared for handmade papermaking: pulp, filter cloth, filter plate, filter box, pressure plate, disposable water cup, water.

1. Put the pulp into a disposable water cup.

2. Add half a cup of water to soak the pulp and stir well.

3. Take out the filter plate and put it in the filter box. Top with a filter cloth.

4. Pour the stirred mass evenly on the filter cloth.

5. Spread another layer of filter cloth on the pulp.

6. Then flatten it with a pressing plate.

7. Pour out the excess water in the filter box.

8. Put the filter cartridge aside for natural air drying, and the handmade paper is completed.

9. Complete the drawing.

Handmade paper needs to be rebuilt.

Materials for preparation: pulp.

Filter cloth, filter board, filter box, pressure plate, one-time water cup, clear water.

1. Put the pulp in.

DAO disposable water bottle.

2. Add half a cup of water to soak the pulp and stir well.

3. Take out the filter plate and put it in the filter box. Top with a filter cloth.

4. Pour the stirred mass evenly on the filter cloth.

5. Spread another layer of filter cloth on the pulp.

6. Then flatten it with a pressing plate.

7. Pour out the excess water in the filter box.

8. Set the filter cartridge aside for natural air drying.

Handmade paper is done.

The easiest: put the waste paper in the beverage bottle and soak it and shake it evenly, then pour it on a denser cloth, spread it evenly, dehydrate it and press it tightly to dry.

Plants are rich in fiber.

The lignin-based pulp is obtained by cutting the trees and reeds into pieces and placing them in a large high-pressure container, and adding sodium hydroxide and sodium sulfide to separate the lignin from the fragments. The separated pulp is evenly sprinkled on the paper machine, and various types of paper can be made according to the required settings. The moisture of the pulp is dried and compacted at a high temperature, and calendered with a calender to make a large roll of paper.

Plants are rich in fiber.

The fine paper is made of pure wood pulp fibers. Ordinary paper is fiber plus some sundries, additives.

Bamboo is rich in fibers and can be used to make paper, but because the material value of bamboo is more precious, only some scraps are used to crush and wood, reeds, and waste paper to make paper for different purposes in different proportions.
