The technology of paper production at home, in the factory, in Ancient China

What was not written, the humanity! Rocks, cave walls, wood, clay and stone tablets, bronze columns… Maybe thanks to the latter, arose the proverb about the fact that not every axe can handle written. But none of these materials did not meet requirements in writing. Until then, not yet invented paper.

The Invention of the technology of making paper in China for a long time attributed to the Cai Luni, Imperial dignitary. At least, it was he first gave to the Emperor of China a petition for the widespread implementation of his method of making paper. Scientist dignitary in a special way mixed hemp and mulberry fiber, ash, water, fabric scraps, laid them in a form, and leveled as did the manufacturers of parchment and papyrus. The Emperor approved the petition. And so it happened that, while similar material in China, made long before the petition dignitary, the invention of paper is attributed to him.

The Technology of paper production has evolved in each country and over time, paper became the most popular, although not very high quality material.

In 1770, the Paper manufacturer was able to create the installation, delivered prepared paper on the traces of the form in which it was dried. After 30 years in France built the first paper machine. Since then, the paper had become known everywhere and ceased to be a deficit.

Today, the technology of paper production is quite simple and consists of several stages.

In the first stage to prepare the feedstock. Cut pine and spruce, cut them into boards, sanded on special machines by the method of dry okurivanie. Peeled bars are milled to the state of the chip.

The Second stage - the production of semi-finished product. The technology of paper production implies that wood masnih shops carefully prepared wood chips are ground into wood shredder, turning it into wood pulp. In these shops a lot of bleach and thicken.

At the third stage, the wood pulp and thermomechanical mass mixed, add pulp, sorted, bleached again, and only then sent to the machine for the production of paper. The grids of these machines formed the fabric from which the press squeeze the water. Then the paper is dried in the cylinders, make more smooth with the help of calender shafts, wound on knurled rollers, cut to the desired formats.

This paper making technique has only one drawback: it greatly reduces the amount of wood on the Ground.

Every stage of industrial manufacture of paper has its own name.

• Pre-processing or storage. Raw material is ground, mixed with fillers, coloring or bleaching substances enters storage musaliny the pool, whose task is to ensure smooth operation of paper machines.
• Refining, i.e. the alignment of the structure of the paper pulp.

Today, some countries (particularly Japan) for Souvenirs made paper by hand. She kind of looks expensive, but is a great gift.

Few people know that to make paper you can…home.

Home paper making technique

1. Shred old paper (tissue paper, newspaper, etc.), fill with water, beat with a mixer until you get a uniform "dough".

2. Add glue, stir, spread in a tray of the grid, covered with gauze. Squeeze with your hands, flatten, cover with gauze and lay press.

3. Leave for a few days, turning them over frequently for uniform outflow of water.

This home paper will not differ special beauty, but is quite suitable for souvenir, especially made by children.

This is not the only one, but the easiest way of making paper at home.
