Study on Influence of Moisture Absorption Strength of Adhesive T-Joint

Abstract:

Adhesive is commonly required to fulfil an explicit mechanical role where mechanical properties can affect their performance. The mechanical properties of adhesive are known to vary with moisture content. This paper presents a study of moisture absorption epoxy adhesive joint as alternative to welding joint in urea granulator chamber. Welding joint requires high skills to avoid joint failure. In particular, bulk specimens were exposed to three humidity conditions, namely, 80OC, 90OC, and 100OC at a constant time immersion of 15 minutes in water. Compression test revealed that Young modulus decreased with increasing water temperature. Moisture condition has some effect on the strength of the adhesive bonding with certain thickness. 1.0 mm of adhesive thickness provides the highest value failure load for every thickness and conditional water temperature. Experimental result indicated that failure load of adhesive T-joint at room and 90OC water temperature give relatively high value of strength if compared to water temperature at 80OC and 100OC.
