Nowadays, adhesives are required in many household appliances, communication devices, means of transportation, and even in security equipment, new energy sources, military electronics, aerospace, intelligent manufacturing, and medical devices. With such a wide range of applications of adhesives, do we really understand them? And what are their advantages?
Firstly, it can connect various materials with different elastic moduli and thicknesses, especially thin materials. Moreover, the bonded surface is smooth and has good aerodynamic performance. Its sealing performance and corrosion resistance are also excellent. Most importantly, it can extend the service life of the bonded parts and reduce their weight.
To ensure the quality of adhesives when using them, the following points should also be achieved:
(1) Select the adhesive that is suitable for the specific use.
(2) Take into account both the high strength and good durability of the adhesive.
(3) Do not use adhesives that have exceeded their storage period and applicable period.
(4) If a single-component adhesive is stratified or precipitated, it should be stirred evenly before use.
(5) Multi-component adhesives should be mixed evenly according to the specified proportion.
(6) Do not adopt simple butt joints.
(7) Try to use lap joints, miter joints, sleeve joints, and mixed connections.
(8) The lap length should not be too long.
(9) For glued laminated materials, do not use lap joints, and miter joints should be used instead.
(10) Add screws and rivets, roll the edges and cover the corners to prevent peeling.
There are numerous classifications of adhesive products, and their functions and uses also vary. When selecting an adhesive, it is necessary to choose the corresponding adhesive according to the product, material, and the scenario of using the adhesive.
