The term “surface sizing” refers to starch and other polymeric materials that are spread over the surface of the freshly made paper at a further stage in its production. Factors in the selection of an appropriate size test include speed, reproducibility, and degree or correlation with end-use issues.
Surface Sizing. Materials (usually a starch solution) added to the surface of a partially dried paper web as a means of sealing surface fibers and increasing sheet strength and resistance to stresses.
When we compare internal and surface sizing, some significant arguments crystallize out, which speak for surface sizing. Polymeric surface sizing agents are generally applied, together with starch solutions, so that the internal and surface strength of the paper increases. The yield of the surface sizing agent is 100 %. It is possible to ...
23 maj 2018 · Paper surface hydrophobization, also referred to as .surface sizing., is often necessary for printing and packaging purposes. Typically, hydrophobic polymeric nanoparticles, in combination with starch are applied on the paper surface at the dry-end of the paper machine.
Introduction to pigment coating and surface sizing of paper and board.
1 mar 2002 · Surface sizing with cationic starch also gave better picking resistance and ink receptivity for coated paper than ammonium persulfate starch.
Solenis offers a wide array of sizing agents to help papermakers improve the aqueous holdout of their products, whether it be a printing paper or packaging board that must meet a specific performance standard, such as the UN Cobb water absorption test.
