In this study, a new technical process for hardening wood fiber insulation boards is introduced. During the dry-process, the fibers are usually glued with polymeric-diphenylmethane-diisocyanate (pMDI) and hardened to wood fiber insulation boards using a steam-air mixture. However, the maximum temperature reached in the steam-air process was 100 °C, and it was impossible to use an alternative bi...

The interfacial oxidation behavior of Cr4Mo4V high-speed steel (HSS) joints undergoing hot-compression bonding was investigated by using optical microscopy (OM), scanning electron (SEM), and transmission (TEM). In the heating holding processes, dispersed rod-like granular $$\delta - {\text{Al}}_{{2}} {\text{O}}_{{3}}$$ oxides were formed at interface in matrix near due to selective internal Al,...

Hot air drying of palm fruit is a simple method but results in low grade oil. The steaming high oil it requires wastewater treatment process. Both methods have both advantages and disadvantages, therefore if they were combined, can result the better grades oil, which should be encouraged for farmers Thailand to apply. This research aimed determine mechanical characteristics semi-damp dryer palm...
