Paper chemicals designate a group of chemicals that are used for paper manufacturing, or modify the properties of paper. These chemicals can be used to alter the paper in many ways, including changing its color and brightness, or by increasing its strength and resistance to water. [1] The chemicals can be defined on basis of their usage in the ...
In industrial paper-making processes, organosolv is a pulping technique that uses an organic solvent to solubilise lignin and hemicellulose. It has been considered in the context of both pulp and paper manufacture and biorefining for subsequent conversion of cellulose to fuel ethanol.

Coating components are subject to particle-particle, particle-solvent, and particle-polymer interactions. [1] Van der Waals forces, electrostatic repulsions, and steric stabilization are the reasons for these interactions. [2] Importantly, the characteristics of adhesion and cohesion between the components form the base coating structure.
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 .
The density of paper ranges from 250 kg/m 3 (16 lb/cu ft) for tissue paper to 1 500 kg/m 3 (94 lb/cu ft) for some specialty paper. Printing paper is about 800 kg/m 3 (50 lb/cu ft). [22] Paper may be classified into seven categories: [23] Printing papers of wide variety. Wrapping papers for the protection of goods and merchandise. This includes ...
Mass deacidification—along with microfilm and lamination—was developed during the early and mid-20th century as a response to the chemical process of hydrolysis by which the fibers that constitute paper, providing its structure and strength, have their bonds broken, resulting in paper that becomes increasingly brittle over time.
