Research of adhesive dosing possibility of glued laminated lumber technology
Abstract
Abstract Since the glue is not an ideal liquid for which the laws of its expiration are generally known, the purpose of our work was to determine the duration and speed of the resin outflow from the container, depending on 2 factors - the height of the container with the resin above the surface on which the resin is applied, and the conditional viscosity of the resin within its working value. As a result of the conducted research, it was found that it is possible to dose the glue in the glued beam technology, when using low-viscosity resins, by lifting the container with the resin (glue) above the level of the surface on which it is applied. Moreover, for low viscosity fluids with a viscosity up to 80 °C (on the examples of water and resin low viscosity) observed increase in flow rate from the container increasing the height of the rise of liquids over the surface to which it is applied. As the resin viscosity increases from 80 to 131s the absolute value of the resin flow rate from the container decreases.
