Second, the surface is sticky and has a large residual odor
1, the cause of the failure
1 Insufficient UV light intensity, lamp aging, failure to fully cure and dry.
2 Non-reactive diluents (ethanol, etc.) are added excessively, affecting the complete curing of UV varnish, especially in the case of low temperature and high humidity, this effect is more serious.
3 coating is too thick or severe uneven.
4 The speed of the coating machine is too fast, and the curing and drying speed of the UV varnish is not suitable.
The reactive diluent in the 5UV Varnish is of poor quality, has a large odor and is not suitable for photoinitiators, resulting in large residual odor.
6 The storage time of the varnish is too long, causing gas accumulation in the container.
7 printing ink does not dry, affect the UV varnish completely cured.
2, elimination method
1 To ensure that the UV varnish is fully cured, it is the most effective way to avoid surface stickiness and reduce the residual odor of varnish.
2 The output power of the high pressure mercury lamp should not be less than 120W/cm.
3 Replace the lamp in time. UV lamps generally have a service life of about 1000 hours. Frequent startup will greatly shorten the service life. UV curing depends on the effective UV wavelength emitted by the high-pressure mercury lamp. Aging means that the effective UV wavelength decreases, so the lamp cannot be off or The ring is replaced.
4 The use of non-reactive diluents should be minimized, and the temperature of the photo-curing process should be appropriately increased to help volatilize non-reactive diluents and reduce the interference with photo-curing.
5 Select the type of UV varnish with fast curing and low odor.
6 When necessary, a certain amount of UV varnish curing accelerator can be added to accelerate the complete curing and drying of the UV varnish, and the addition amount is generally 2% to 5%.
If you are walking in a park or in your own backyard, you can't help but stop and gaze at the small Water Fountain since it appears to be so healing. This circular garden water feature gives a modern garden space a sophisticated feel by giving it a fantastic industrial edge. The elevated, flat steel bed that makes up the garden water feature is completely submerged in water, bringing out the lovely tones of the worn steel below. A babbling spring of water bubbles up from the center of the bed and, when it falls, creates a ripple of concentric circles in the pool. The edge of the bed is lapped by pool water. made of naturally self-rusting corten steel, which doesn't need painting or upkeep to maintain its visual appeal without compromising its structural strength.
Adaptable contemporary design for both indoor and outdoor spaces
has all you need; there is no need for additional purchases.
