In the electronics industry, can a display screen made of acrylic material bonded with UV glue be irradiated by a leduv curing ultraviolet lamp for one second?

In the electronics industry, when using UV glue to bond acrylic displays, one second of irradiation by an LED UV curing ultraviolet lamp is usually not enough. The curing time of UV glue is affected by multiple factors such as ultraviolet intensity, glue thickness, and temperature. Generally speaking, for acrylic-specific UV glue, it is recommended that about 6 seconds of light irradiation is needed for initial positioning, and a longer time is required for complete curing. Moreover, different brands and models of UV glue also have differences in curing time. For example, the 3312 plastic bonding UV glue of a certain glue company in Dongguan City can be initially fixed in 3-5 seconds and reach strength within 10 seconds in an ultraviolet light source environment with a wavelength of 365nm or 395nm. If the irradiation time is too short, the glue cannot be fully cured, which will lead to insufficient bonding strength. The display screen may have problems such as falling off and unsealing in subsequent use.
