What were the scientific and technological creations in ancient China?

Papermaking is an important invention of working people in ancient China. There are two forms: mechanical and manual. The mechanism is continuous on the paper machine. The paper pulp suitable for paper quality is diluted to a certain concentration with water, and is preliminarily dewatered in the wire section of a paper machine to form a wet paper sheet, then dewatered by pressing, and then dried into paper.

Step 2 print

Printing is a technology of making plates, inking and pressurizing original texts such as words, pictures, photos and anti-counterfeiting, so that the ink can be transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials, and the original contents can be copied in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

3. Textiles

The original intention of textile is taken from the floorboard of spinning and weaving, but with the continuous development and perfection of textile knowledge system and discipline system, especially after the emergence of nonwoven materials and three-dimensional composite weaving, there are not only traditional hand-spinning and weaving, but also garments, industrial and decorative textiles produced by non-woven, modern three-dimensional weaving technology and modern electrostatic nano-netting technology.

4. Pottery

Ceramics is the floorboard of pottery and porcelain, and it is also a kind of arts and crafts in China. As early as the Neolithic Age, there were rough and simple painted pottery and black pottery in China. Pottery and porcelain have different textures and characteristics. Pottery, made of clay with high viscosity and strong plasticity, is opaque, with fine pores, weak water absorption and turbid tapping sound.

5, metallurgy

Metallurgy is a process and technology to extract metals or metal compounds from minerals and make metals into metal materials with certain properties through various processing methods.

Metallurgy has a long history, from the Stone Age to the later Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development has integrated the history of metallurgical development.
