What details should be paid attention to when operating UV glue?

UV glue general-purpose products have a wide range of applications, and the bonding of plastics and various materials has excellent bonding effects; high bonding strength, through the destruction test, the plastic body can be broken without degumming, and the UV glue can be almost Positioning in seconds, achieving high strength in one minute, greatly improving work efficiency; completely transparent after curing, the product will not yellow or whiten for a long time; compared with traditional instant adhesive bonding, it has ring test resistance, no whitening, and flexibility Good sex and other advantages. What are the operating details of the UV glue introduced by the saliva glue manufacturer?

1. One of the two objects to be bonded is transparent and the surface is cleaned, dry and free of grease;

2. Apply UV glue on one of the surfaces, close the two planes, and irradiate it with a suitable wavelength (usually 365nm-400nm) and energy ultraviolet lamp or a high-pressure mercury lamp for lighting. The illumination should be from the center to the periphery, and Confirm that the light can really penetrate to the bonding part;

3. It is recommended to illuminate for about 6 seconds. When initial positioning, remove the remaining glue on the workpiece and re-illuminate until it is completely cured;

4. The curing time should be different according to different preparation materials, glue thickness and UV intensity. It is recommended that users purchase an ultraviolet intensity tester, and perform a light intensity test before bonding to reduce the rejection rate;

5. The temperature has a little effect on the activity of the glue, and the curing time should be extended appropriately when the temperature is low;

6. Do not apply force to squeeze and repeatedly rub the materials to be bonded during operation, and it is recommended to use fixed tools;

7. When bonding plastics, the content of UV absorbers in the plastics should be considered. A high content will seriously affect the transmittance of UV rays, which will also have a significant impact on the curing efficiency of the glue, and even cause the glue to fail to cure;

8. It is recommended to use low-viscosity products when bonding large areas. When conditions are available, purchase vacuum equipment and attach in a vacuum environment to remove air bubbles and increase the yield;

9. The above instructions are for reference only, and the specific operation needs to be adjusted by the customer according to the specific situation.
