Bonding is the method of firmly joining together the same or different materials by the adhesive force exerted on the solid surface by the adhesive. There are two main forms of bonding: unstructured and structural. According to reports, non-structural bonding mainly refers to surface bonding, sealing and functional bonding. Typical non-structural adhesives include adhesives for surface bonding, sealing and conductive adhesives; and structural bonding is the use of adhesives for structural units. Bonding that is firmly fixed together. The structural adhesives and their bonding points used must be able to transmit structural stresses without affecting their structural integrity and environmental applicability within the design range. The ring particles can be bonded to PMMA, PC, PET materials, etc.
