In-Line Preparation System for the Paraffin Emulsion used within a Particleboards Manufacturing Line

Abstract

The properties of particleboards greatly depend on the raw materials and additives used in their composition. Paraffin emulsion is one of the additives widely used to improve the surface absorption and thickness swelling of particleboards. Industrial paraffin emulsion contains a large number of filling materials which increase the solid content unnecessarily, with a negative impact on the properties of the boards. Additionally, the high amount of oil contained by the industrial emulsion causes spots on the panel surface. These shortcomings lead to the necessity of developing an original system for the in-line preparation of the paraffin emulsion. The basic design and the benefits obtained, as well as the results of the measurements regarding ammonia emissions, are presented in this article. The developed solution was efficiently implemented at the industrial level.
