Paper is very commonly seen in our daily life. We consume a lot of paper products such as toilet paper, tissues, paper bags, and writing papers every day. However, since most kinds of paper are made of wood pulp, which is made of trees or other plants, the increase of paper consumption will lead to
With today’s increasingly high energy and chemical costs and stringent environmental regulations, the need for improved recovery of chemicals from the pulp and paper making process has become a critical economic factor in the industry. It is essential that mills maximize steam and power production capacity, reduce recirculating chemical dead loads, and minimize chemical losses.
Paper plays an important role in our daily life. It is one of the greatest inventions in human history. Paper can be made from pulp of wood, grass, waste paper or other materials. Paper manufacturing processes are as follows: The pulping process, it separates and cleans the fibers Refining process would be followed after the
Paper is actually a multi-functional biomass product, which can be made of renewable woods, grass, rags, waste paper, and other materials. No matter which material is used for papermaking, the first step is always to dissolve the material into pulp. Modern pulp production is based on the best available technologies and concepts, creating more products
History of Paper Manufacturing Process Formed from wood pulp or plant fiber, the paper is chiefly used for written communication. The earliest paper was papyrus, made from reeds by the ancient Egyptians. Chinese paper was invented in the second century, probably by a Chinese court official named Cailun. His paper was made from tree barks
The Notices on the Use of Recycled Fiber Wood is the main raw material for papermaking. However, with the decrease of forest resources and the increase of human demand, the wood problem has become more and more serious. To solve the dilemma from the lack of raw materials, the utilization of waste paper and fully
