Analysis of heat and mass transfer process while cooling particle boards produced on low-toxic resins

Abstract

Particle board production technology is a complex process including a number of important operations, and the quality indicators of the finished product largely depend on it. One of such operations is cooling of hot plates after pressing. Increasingly, low-toxic resins are used in particle board production. However, the modes of post-press exposure of particle board on resins with low formaldehyde content should differ from the well-known ones. Therefore, the purpose of this work was to develop a mathematical model (a system of equations), that will theoretically calculate the duration of plate cooling, as well as display the temperature on its surface and over the cross section for any time interval. As a result of the work carried out, a mathematical model has been proposed that enables theoretical calculation of cooling duration of particle board produced on low-toxic resins and to display the temperature on its surface and over the cross section at any time interval.

Experimental Granulometric Characterization of Wood Particles from CNC Machining of Chipboard

“…Particle board (chipboard) is a material used in the production of cabinet furniture and construction. The popularity of chipboard is also due to the fact that manufacturers of this board material are trying to introduce the promising developments of scientists, to keep up with the times [22,23]. The technology for the production of particle boards is a complex process including a number of important operations.…”
