Sankun touch screen UV adhesive curing standard science and technology
Touch screen UV glue curing standards are usually based on UV energy value measured by (mj/cm2), actually this is not accurate. As we all know the sun's rays is ultraviolet (UV), as well as energy (summer outdoor maximum 3.5 mw/cm2 at noon of UV light intensity), can also with UV high pressure mercury lamp can achieve the same value, but at the same energy of the sun's rays are no substitute for UV high pressure mercury lamp, the reason is that the sun's ultraviolet intensity (mw/cm2) is too weak, the lack of penetration. Can be seen from the UV curing glue can not only see the UV energy, UV glue under different intensity of UV curing energy value is different, the stronger curing UV ultraviolet glue when the less energy is needed to, on the contrary the lower the intensity of the ultraviolet energy needed for the more, the intensity of the ultraviolet low even more energy cannot make the UV glue solidified completely.
Different kinds of UV glue for UV lamp types of requirements are different, more commonly used is the UV metal halogen lamp (hereinafter referred to as the halogen lamp) and UV high pressure mercury lamp (hereinafter referred to as the mercury lamp), they all UV peak values differ (see chart), main peak is 365 nm mercury lamp, halogen lamp, the main peak is 365 nm, 380 nm. UV glue is a kind of modified acrylic resin structural adhesive, UV adhesive curing principle is light initiator of UV curing materials (or photosensitizer) under the irradiation of ultraviolet absorption after UV reactive free radicals or cationic monomer polymerization by, crosslinking and the chemical reaction, make its in seconds from liquid into solid. Light the play a key role of the initiator, different light initiator on the wavelength of ultraviolet radiation sensitivity is not the same, halogen lamps with double primary wave, so it's suitable for wider than mercury lamp. In mercury lamp and halogen lamp under the condition of same energy halogen effect more apparent than mercury lamp, they are not simple comparison on energy.
And there's a little glass cover, PC, PET and UV transmittance of polaroid has difference, will affect the UV glue ultimately curing effect.
So just use energy to measure whether the UV glue solidified completely is a myth, what should be integrated in the use of cover plate using what type of UV lamp, light intensity is the range of energy to make the UV glue solidified completely, the key is to test for a cured product, energy is only a reference, not absolute.
