First, the significance of the detection of sealant.
Sealants play an important role in electronic components and industry, and a series of sealant tests are required to ensure that their quality and performance meet the design requirements. In the field of adhesive testing, adhesion performance is one of the landmark indicators to evaluate its performance. For sealant quality testing, the bonding performance with the substrate is the key to ensure the sealing performance. Peel strength testing of sealants is a test of the adhesion of sealants to various substrates under peel forces and under different aging conditions. Through these tests, we are able to fully evaluate the quality and safety of the sealant and select the right sealant for different applications.
Second, the detection method of sealant.
Shanghai Baosheng TAThe XTC Sealant Tester tests the basic properties of sealants, including durability, tensile strength, shear strength, hardness, and bond strength. Tensile strength and shear strength tests are used to evaluate the tensile and shear resistance of a glue. The hardness test is to evaluate the softness and pressure resistance of the glue by measuring its hardness. Bond strength tests are used to evaluate the adhesion between adhesives and different materials. According to the different forms of force on the adhesive bonding surface, we test the different stresses required when the bonding system is broken, and this stress is the bond strength. Different bond strengths can be divided into shear strength, tensile strength, uneven tear strength, peel strength, compressive strength, impact strength, bending strength, torsional strength, fatigue strength, creep strength, etc.
