The speed of UV glue curing has always been a concern for consumers. Measuring the quality of UV glue is good for many reasons: positioning time, depth of cure, strength, and flexibility of the film. We believe that the faster the positioning speed, the greater the internal stress generated when the glue cures. This may cause the aluminum plate to fall off. The general positioning speed is preferably 6 to 10 seconds. Therefore, judging the quality of the shadowless glue alone is not correct. Here we come together to understand the relevant knowledge of UV glue. Ultraviolet Adhesive Advantage I. Environment/Security 1. No pollution to the ambient air; 2. Limited or prohibited ingredients; 3. Low flammability. Second, economy 1. Curing speed, improve labor productivity 2. Can detect, carry 3. Save energy. 90% energy saving compared to thermosetting resins 4 simple equipment, save space 5. Easy to use Third, compatibility 1. For moisture sensitive materials can be used 2. Control the curing time 3. Repeatable sizing, multiple curing 4. Easy to install without major changes UV glue defects 1. Raw material cost and price are high. 2. The penetrating power of some materials is weak, and curing is limited. 3. The opaque materials need to be combined with other technologies, such as photothermal double curing. UV glue operation instruction 1. Clean the surface of the bonded object; 2. Light from the center to the periphery, confirm the light to the bonding site; 3 light around 6s. Relight until completely cured; 4. The curing time varies according to the material. 5. Low temperature, long curing time; 6. It is recommended to use fixed tools; 7. Consider the content of UV absorbers in plastics. 8. Purchase vacuum equipment to remove air bubbles and improve yield; 9. The specific operation to make appropriate adjustments according to specific circumstances UV glue use method 1. Pay attention to the amount, apply too much, not easy to cure, and will produce bubbles. The thickness is controlled at 0.04 to 0.06 mm. 2. It is best to use some sizing tools when applying adhesives. 3. If there is a bubble before using the adhesive, place it in a cool place for 24 hours. Editor's summary: The above is the introduction of the advantages and disadvantages of UV glue and the use of the relevant knowledge, hope to help friends who have this need!
