本研究係觀察乙基纖維素(Ethyl Cellulose)分別添加於以特品醇(Terpineol)及B.C.A.(Diethylene Glycol Monobutyl Ether Acetate)兩種溶劑為主之承載媒體(Vehicle)中的流變行為，並藉由改變乙基纖維素的含量觀察其對流變行為的影響。
本研究運用流變儀(Rheolometer)以穩態方式量測屈服應力(Yield Stress)、搖溶性(Thixotropy)及各種不同剪切速率下之黏度值，並以動態方式量測黏彈性等流變性質。研究中發現特品醇對乙基纖維素屬於良溶劑，能使乙基纖維素分子鏈充分展開，增強三度空間網狀結構之糾結，致使系統擁有較高的黏度值、屈服應力值、較大之搖溶性及穩定之動態性質等特性；在良溶劑系統中，乙基纖維素對系統之流變性質有重要的影響，相對在不良溶劑中乙基纖維素對流變性質影響則不顯著。
另本研究藉由觀察不同樹脂含量及不同溶劑系統中承載媒體之流變行為，進ㄧ步探討溶劑選用及樹脂對系統流變性之影響，並藉以控制網板印刷所使用漿料(Paste)之黏度、搖溶性及黏彈性等條件，以調製符合網板印刷需求之漿料。

My thesis is aimed to observe the rheology properties of different ethyl cellulose contents by adding Terpineol and B.C.A. (Diethylene Glycol Monobutyl Ether Acetate) as a vehicle.
The yield stress, thixotropy and viscosity under different shear rate were studied by steady measurements means of Rheometer. The storage and loss modules were measured by dynamic testing.
The experiment results show that Terpineol is a good solvent for ethyl cellulose compared with B.C.A. The molecular chains of ethyl cellulose can be fully extended in Terpineol which results in a better 3-D network entanglement. These network structures provides higher values in viscosity, yield stress, thixotropy and better stability in dynamic measurements. In good solvent system, Terpineol, ethyl cellulose has great impaste in blending the pastes. In poor solvent system, B.C.A., ethyl cellulose has not great impaste in the flow properties of paste.
Through our researches, we know to choose a proper solvent to gain the past of mask printing via observing how different binder and solvent contents effect the theological properties of vehicle. Due to gain the past of mask printing, we change viscosity, thixotropy to achieve a recipe of solvent according to different binder contents and rheology system.
