主研究擬自行組裝一測量熔融玻璃液滴之動態潤濕行為量測系統。潤溼現象之探討乃藉著熔融玻璃固著液滴接觸角之測量而得。
首先自行組裝一適用於高溫熔融玻璃液滴之量測裝置、撰寫連續取像程式和液滴邊界自動搜尋程式、建立固著液滴之接觸角量測方法，繼而探討接觸角隨溫度和加熱時間的變化情形，進而得知不同材質的熔融玻璃液滴在不同固材上之動態濕潤行為。
在固著液滴之接觸角量測部份：POI玻璃於不同基材（金屬：Pt、Pt-Au合金、Pt-Rh20合金；非金屬類：新、舊耐火磚）上的潤溼現象不盡相同。POI在Pt上潤溼溫度較低，於合金基材上之潤濕現象幾乎相同，於新耐火磚上潤溼溫度則高於金屬基材。不同玻璃 (POI、C18、N8) 於新耐火磚基材上的潤溼溫度：C18 > POI = N8。

A system for the studying the wetting phenomenon of melting glasses is developed in this work. The wetting behavior is via the measurement of dynamic contact angle of the melting glasses. An apparatus for measuring the melting glasses at temperature ranging between 800 and 1600 oC is built first. A program for acquiring drop images continuously and for locating the edge coordinates is then developed. After that, this contact angle of sessile drop of melting glasses is measured at different temperature and different heating time. The wetting phenomena are then studied from the dynamic contact angle data for various melting glasses at different solid substrates.
The data of contact angle show some interesting results. Different wetting phenomena were observed for POI melting glass on various solid substrates, which includes metals (Pt, Pt-Au alloy, and Pt-Rh alloy) and non-metal (two different refractory bricks). The temperature for POI glass reaching a constant contact angle is: Pt < alloy < non-metal. The temperature for different glasses on the new refractory to reach a constant contact angle is: C18 > POI = N8.
