Pulp and Paper Technology
A literature survey shows that a great deal of work has been done on beater additives. It also showed that there is little or no agreement among workers in this field.
Laboratory work was carried out comparing blends of pulp made up of a sulphite pulp beaten to a "gelatinized" mass and a kraft pulp beaten to two different freeness levels with the same kraft pulps to which guar gum and oxidized potato starch had been added. Results show that guar gum is the best strength developer when both millen and tear are considered.
