The surface chemical composition is differentiated by the adsorption of acrylic acid or an anionic surfactant, both of which are used for stabilization of the dispersion in water. [8] Co-binders, or thickeners, are generally water-soluble polymers that influence the paper's color viscosity, water retention, sizing, and gloss.

Paper is a thin sheet material produced by mechanically or ... Book publishers tend to use acid-free paper, made from fully bleached chemical pulps for hardback and ...
Machine-finished coated paper (MFC) has a basis weight of 48–80 g/m 2.They have good surface properties, high print gloss and adequate sheet stiffness. MFC papers are made of 60–85% groundwood or thermomechanical pulp (TMP) and 15–40% chemical pulp with a total pigment content of 20–30%.
The chemical formula of cellulose is (C 6 H 10 O 5) n where n is the degree of polymerization and represents the number of glucose groups. [ 21 ] Plant-derived cellulose is usually found in a mixture with hemicellulose , lignin , pectin and other substances, while bacterial cellulose is quite pure, has a much higher water content and higher ...
Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack kraft paper (or just sack paper ) is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.
In the United States, paper companies have consumed nearly all of the black liquor they produce since the 1990s. [8] As a result, the forest products industry has become one of the United States' leading generators of carbon-neutral renewable energy, producing approximately 28.5 terawatt hours of electricity annually.
Chemical reactions other than acid–base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white; the litmus dye is bleached [4] because hypochlorite ions are present. This reaction is irreversible, so the litmus is not acting as an indicator in this situation.
