Zirocnia Ceramics:
Zirconia Ceramic blocks In order to prolong the life of paper, a new technology of dyeing paper has been invented in Jin Dynasty, that is, the juice is boiled from yellow tiller, and the paper is impregnated. The impregnated paper is called dyed paper, which is natural yellow, so it is also called jute paper. Yellow paper has the function of killing insects and moths.
By the Jin Dynasty (4th century), paper had finally replaced silk slips as the main writing material. Cai Lun played a great role in promoting the production of hemp paper and vellum paper. Although he was not the inventor of papermaking, his historical status as a technological innovator and organizational promoter should be affirmed. In the 8th century AD, paper was widely used in our country. In the following centuries, our country exported paper to various parts of Asia, and strictly kept the secret of papermaking. In 751 AD, the Tang Dynasty and the Arab Empire clashed, and the Arabs captured several Chinese paper craftsmen. It didn't take long for the paper industry to sprout up in Samarkand and Baghdad. In this way, papermaking technology gradually spread all over the world, where paper was widely used, and then spread to North America and Europe through the Arab countries.
