Wetting of an ideal flat surface solid liquid θ Dry if θ> 0 (partial wetting) Wetted if θ= 0 (total wetting) Young relation: cos θ= σ SV - σ SL σ Surface tensions.   Average wetting factors for Modified Surface C and Modified Surface D are found to be and respectively. Modified surface C improves average wetting factor of plain PP by around %, which is around % more than plain metallic surface Al. Modified Surface C wetting factor is around % higher than SLS ppm solution wetting Cited by: 8. The optimal solution was the minimum Q of KJ, which can be obtained with a pressure of MPa, temperature of °C, and veneer number of 5, which makes CA and MOE for the hot-press-dried.

wet-web strength, of never-dried, once-dried, and once-dried cellulase-treated furnishes. We also measured the effects of drying and enzyme treatment on burst strength and viscosity. MATERIALS AND METHODS A commercial enzyme preparation consisting of cellulases was used in the laboratory experiments and papermachine run.

Chow, , Determination of resin distribution in flakeboard using x-ray spectrometry.   Alternative drying methods have been investigated, such as a contact drying method that dries veneer by contact with a hot platen on one surface and by the application of a partial vacuum to the other surface (Paajanen et al., ). This method is claimed to reduce dying time significantly and may result in overall energy savings, however, at. Many studies have been conducted on the effect of veneer-drying temperature on the ability of veneer surfaces to bond [24,25], on the relationship between surface inactivation and bonding strength.

According to the IPC standard, non-wetting is defined as the inability of molten solder to form a metallic bond with the base metal. The potential of near-infrared spectroscopy (NIRS) to estimate moisture content (MC) and surface inactivation parameters of Douglas-fir (Pseudotsuga menziesii var. menziesii) veneer products was. veneer plies, the order of layers, the adhesive used, and the The wet mats are then dried to the nal. moisture content.
