Science and technology in China
Papermaking is the manufacture of paper and cardboard , which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery , while handmade paper survives as a specialized craft and a medium for artistic expression. In papermaking, a dilute suspension consisting mostly of separate cellulose fibres in water is drained through a sieve-like screen, so that a mat of randomly interwoven fibres is laid down. Water is further removed from this sheet by pressing, sometimes aided by suction or vacuum, or heating. Once dry, a generally flat, uniform and strong sheet of paper is achieved.
New technologies concentrate on the by-products of pulp production and on creating green energy. The focus on developing low-effluent and chemical recovery systems for chemi-mechanical pulp mills continues. Consumption of fresh water has also decreased. Technology development in evaporation is focusing on producing highly efficient, low or zero effluent evaporation systems. White liquor plant development is further reducing gaseous emissions and cleaning solid wastes to reduce toxicity.
