A Chemical Of Many Uses Lime In The Pulp And Paper

Chemical Pulping. Chemical pulping removes lignin from lignocellulose. The resulting cellulose fibers may be used for paper production or chemical cellulose for manufacturing cellulose derivatives such as carboxymethyl cellulose. Pulping conditions tend to be so harsh that hemicellulose is hydrolyed and removed from the fiber
