Although bonding technology has unique properties and advantages, as you can greatly simplify the process, address some key issues, but sometimes can not fully ensure structural reliability. In order to increase the reliability and durability of the adhesive, to take appropriate structural adjustments. Reinforcement measures and other methods is necessary. But, what are the ways and means should be considered depending on the specific conditions of the adhesive. Generally, there are several ways.
① mechanical reinforcement, including nesting, metal fastening, patching, screws riveting, welding, wear pins, bushings, etc., in fact, continue to connect with the mix.
② bonding glass cloth, glass fiber winding, after curing the adhesive becomes glass, steel, in order to effectively improve the structural strength.
③ plus rivets, edging, corners, widening, thickening and so improve the bonding peel strength.
④ The chemical surface treatment, can greatly improve the adhesive strength and adhesion durability.
⑤ bonding surface treatment using the coupling agent, the adhesive strength, water resistance, heat resistance, can improve anti-aging properties.
⑥ After the adhesive parts of the heat treatment such as ultraviolet light irradiation or heating electric hair dryer, can contribute to more fully cure the adhesive, the degree of crosslinking can be increased to increase the adhesive strength and creep resistance.
⑦ glue seam exposed parts of silicone resin waterproof material waterproof, moisture protective layer to prevent erosion and prevent debonding to delay the service life of the adhesive member.
