“Overcured” thực sự có nghĩa là gì?

“I have been taught that over-sự chữa bệnh means you cure a nail product in a đèn uv longer than a manufacturer prescribes / recommends. I understand what happens when a nail product is not cured long enough. But let’s say, a sơn móng tay has to cure for 30 seconds to chữa bệnh đúng cách – what will happen if I work per 1 or 2 fingers? If a proper cured product goes into the light again (and again and again…) and get another full cure? Is that also overcure? It’s not possible to cure a product 180%, am I right? Will the ‘extra’ cure cause any problems?”

Thank you for your question! It is a good one.

‘Overcure’ does not mean too long in the lamp. Once a lớp phủ is properly cured it will not cure any more. All but a small percentage of monome have polymerised. The few that are remaining cannot move around anymore to form polyme chains, but they will not be a problem during removal.

This is why it is fine to keep replacing the nails in the lamp for further layers. So, in this sense you cannot ‘overcure’. Also, nails are in daylight and sunlight and this will not affect it for the same reason.

What ‘overcure’ means when thinking about the ‘proper cure’ is when the sự trùng hợp process is too fast, and the exothermic reaction (heat) can be felt and possibly burn the giường móng tay.

This can happen if a UV lamp that is not matched to the Gel tia cực tím system is used so the UV energy is too high. Or it can happen if the coating is too thick so the level of monomers in the process is so high that the heat can be felt. Or it can happen if the tấm móng tay is very thin making the nail bed sensitive.
