3542PUR structural adhesive Instructions: Please emptied before dispensing plastic nozzle short glue. The JSW3542 structural adhesive heated at a constant temperature 110 ℃ melting, using glue dispensing equipment needs to be bonded to the site within two minutes to complete the fit, and dwell in a fixed rule of 10 to 20 minutes, before moving to the next a station. Each structural adhesive is recommended not more than three hours of continuous warming, with a structural adhesive heating can not be repeated three times. Long heated hose will come into contact with the rear of the air temperature and the formation of the crust, can pierce the crust in order to reduce the gluing pressure. The above is a brief introduction of structural adhesive, need details please go gold Shengwei Guan network download. The following is an informal structure of plastic materials for reference purposes only. After the success of structural adhesive unified theory, people explore the role of the strong interaction and the weak, unified electromagnetic interaction between the three models proposed a variety of grand unified theory of structural adhesive. This theory predicts that structural adhesive will decay, and its life is about 12 ± 2 years. But the experiment has not been confirmed on. When exploring the structural adhesive unified theory of gravity can not be considered. But the force of gravity and the weak, electromagnetic force, strong force has important differences, because the structure of glue directly associated with measurement of space, time, and it passed by ── graviton spin differs from the other three forces transmitters, coupling constant structural adhesive has dimension ~ (mass) -2, which will appear endless variety of divergence, structural adhesive can renormalization. If we take into account the nature of the nonlinear structural adhesive A. Einstein's gravitational equations proposed, even increasing the quantum theory of gravity, renormalization difficulties. Preliminary study structural adhesive believe gravitational field is also a gauge field, which means that the other three fundamental forces of gravity and logically will eventually unify. But you can see the depth of the structural adhesive problems, there are some key factors that people have not mastered. Modified structural adhesive is a high adhesive strength structural adhesive crosslinked, have good mobility when heated to facilitate coating. Structural adhesive with a rapid melting heating, cooling rapidly (about 4s) can achieve the characteristics of high strength adhesive force. Structural adhesive bonding can meet the requirements of mobile electronic products structural components. Structural adhesive suitable substrates: ABS polycarbonate (PC) PS glass products UV-coated polyester (including DCPD modified) aluminum (anodized better) nickel-chrome plating (rough surface) of the same material or different materials bonded to each other . Structural adhesive for moisture curing polyurethane reactive hot melt adhesives. The main ingredient is isocyanate polyurethane prepolymer. After heating at high temperature, structural plastic adhesive molecules of water or active hydrogen reactive substances in the air and on or adhered to form part of the cross-linked structure, the adhesive strength, performance, resistance to chemicals, heat, hydrolysis, etc. superior general of hot melt adhesive. Structural adhesive bonding and toughness (elasticity) can be adjusted with a thermoplastic hot melt cold-ordinary performance, easy bonding operation can glue Receiving wide range of adjustability big performance. From the point of view of physical chemistry, mechanical action does not produce the factor structure of adhesive Relay, but a way to increase the bonding effect. Structural adhesive to penetrate into the gap is at or irregularities of the adherend surface after curing at the interface region production engaging force, which is similar to the case of the engagement nails and wood or roots implanted soil effect. The nature of the mechanical connection force is friction. Structural adhesive when bonding a variety of materials, TP, glass, etc., a mechanical coupling force is important, but the role of certain solid and smooth surface, structural adhesive of significant.
