Title: A wetting behavior test facility made by theory of rapid infrared heating
Inventor: WU SHYI-KAAN
IPC: G01N13/00
Filed: 2001-08-27
Granted: 2003-09-21
Abstract: Infrared heating is a process of fast heating workpieces by infrared generated from the heated W filament in the quartz lamp. Since the infrared can transmit quartz tube and be focused on the specimen, the specimen is locally heated by infrared. The rest part of furnace is much less heated by infrared. Therefore, infrared heating is a highly potential process with the characteristics of both rapid heating (high-energy efficiency) and rapid cooling (quick heat dissipation). This patent introduces a wetting behavior test facility made by theory of rapid infrared heating. It can be used to accurately measure the wetting behavior (including dynamic wetting angle and spreading area) of the contact between liquid phase droplet and flat solid surface. It is a revolutionary breakthrough, especially in accurately measuring the early stage wetting behavior of the liquid phase droplet.
