How to ensure the uv light intensity of uv lamp?First of all, it is an important prerequisite to

select and install the appropriate power uv lamp according to the printing speed and product

type. The uv light intensity of the uv lamp directly affects the curing time of the uv ink, which is

also a key factor affecting the internal hardenability of the ink film. When the uv light intensity

becomes low, even if the accumulated light amount is increased by increasing the irradiation time,

the hardenability inside the ink film cannot be improved, so the uv lamp tube that exceeds

the actual service life cannot completely cure the uv ink. In order to ensure the curing quality of

uv ink, the uv lamp should be replaced in time after reaching the actual service life.

How to ensure the uv light intensity of uv lamp?Secondly, if the ink contains impurities or the

dust in the production process adheres to the surface of the uv lamp, the uv light intensity will be

weakened, thus greatly reducing the curing quality of the uv ink. Therefore, after the uv lamp has

been used for a period of time, its lamp box should be disassembled, and the uv lamp surface

should be gently wiped with clean soft cotton cloth dipped in anhydrous ethanol to

ensure its cleanness and brightness.

How to ensure the uv light intensity of uv lamp?Finally, the reflector inside the uv light box can

concentrate 80% of the uv light on the printed matter. If the paper powder or dust adheres to the

reflector, it will affect its reflection effect on the uv light. Therefore, in daily production, the reflector

must be cleaned and maintained in time to maintain its best reflection angle and reflection ability.

This work can be carried out at the same time of cleaning the uv lamp tube, that is, clean and soft cotton

cloth dipped with anhydrous ethanol for cleaning. In addition, the condition of the transmitting plate shall

also be checked. Once the surface of the reflecting plate is blackened or uneven, it shall be replaced in time.
