Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...
The construction of the Bãi Bằng paper mill was controversial. [1] This project was signed as a cooperation between Sweden and then North Vietnam in 1969, with construction beginning in 1975. The construction was evaluated by the Chr. Michelsen Institute, an independent, non-profit research foundation based in Norway .
International Paper: Kraft paper mill. Paper engineering is a branch of engineering that deals with the usage of physical science (e.g. chemistry and physics) and life sciences (e.g. biology and biochemistry) in conjunction with mathematics as applied to the converting of raw materials into useful paper products and co-products.

For other uses: emery paper, blotting paper, litmus paper, universal indicator paper, paper chromatography, electrical insulation paper (see also fishpaper), filter paper, wallpaper It is estimated that paper-based storage solutions captured 0.33% of the total in 1986 and only 0.007% in 2007, even though in absolute terms the world's capacity ...
Printing quality is highly influenced by the various treatments and methods used in creating paper and enhancing the paper surface. Consumers are most concerned with the paper-ink interactions which vary for certain types of paper due to different chemical properties of the surface. [8] Inkjet paper is the most commercially used type of paper.
Enormous challenges are posed by the trend towards recycled materials paper as raw material (the so-called secondary fibers), the rapid increase in the volume of cardboard at the expense of printing paper, the growing speeds (> 120 km/h [15]) and production quantities (maximum daily capacity of a single machine >4,500 tons or >1.5 million tons ...
