UV LED 固化机固化光油产品效果实测
One, UV varnish (UV varnish) Introduction
1, UV varnish is a transparent coating, also called UV varnish by some people. Its role is to spray or roll coating on the surface of the substrate after the UV lamp (UVLED lamp) irradiation, so that it is instantly transformed from a liquid to a solid state.
2, UV varnish curing to achieve surface hardening, the main role to make it scratch-resistant role, and the surface looks glossy and shiny, beautiful and textured.
Second, the product characteristics of UV varnish
1, bright and beautiful, round texture, three-dimensional relief, short curing time, strong adhesion, with waterproof, sunlight resistance, strong compatibility, low odor, green, good matching, no bubbles, long service life, good mirror effect, fine film, wide range of use.
Three, UV varnish (UV varnish) application scenes
1, glass, metal, acrylic, plastic (BOPP, OPP, PET, PE, PP, ABS, PVC), light box cloth, wood panel, leather, wall cloth, mural, canvas, aluminum plastic plate, soft film, stone, ceramic, fiber and other materials.
2, cell phone case, display screen, porcelain bowl, tobacco and wine, cosmetics, health care products, food, drugs, daily necessities, cultural goods, audio and video products, backdrop, floor tiles, hardware, furniture, toys, handicrafts, etc.
Four, production process
1, production process: dust removal, UV varnish coating, UV curing.
2, UV varnish pre-treatment process: powder removal, corona treatment, priming oil, the main purpose is to make the printing on the UV varnish to achieve a flat, bright, strong adhesion.
Five, UV varnish curing common problems
Bad luster, brightness is not enough
1, UV oil viscosity is too small, the coating is too thin 2, ethanol and other non-reactive solvent dilution is excessive 3, uneven coating 4, paper absorption is too strong 5, coated anilox roller mesh is too thin, the amount of oil supply is not enough
Solution: According to the different circumstances of the paper appropriate to improve the viscosity of UV light oil and coating volume: absorbent paper can be coated with a layer of primer first.
Sixth, poor drying, curing is not complete, the surface is sticky
1, UV light intensity is not enough 2, UV lamp equipment aging, light intensity weakened 3, UV light oil storage time is too long 4, do not participate in the reaction of diluent added too much 5, the machine speed is too fast
Solution: In the case of curing speed less than 0.5s, generally should ensure that the power of high-pressure mercury lamp is not less than 120W / cm or UVLED lamp light intensity in 700mw / cm, if necessary, add a certain amount of UV light oil curing accelerator to accelerate drying.
Seven, the printed surface UV varnish coating does not go on, blossom
1, UV varnish viscosity is too small, the coating is too thin 2, ink in the ink transfer oil or dry oil content is too high 3, the ink surface has been crystallized 4, ink surface anti-adhesive materials (silicone oil, spray powder) too much 5, coated anilox roller mesh is too thin 6, the problem of the construction process (technical personnel technology is not in place)
Solutions: UV varnishing products required, printing should take appropriate measures to create certain conditions: UV varnish can be properly coated thicker, if necessary, on the primer or the use of special varnish formulations.
Eight, UV varnish coating with white spots and
1, coating and thin 2, coated anilox rollers are too fine 3, non-reactive thinner (such as ethanol) to add too much 4, the printed surface dust and other more impact
Solution: keep the production environment and the printed surface clean; increase the coating thickness; add a small amount of smoothing additives: weighing the releasing agent is best to participate in the reaction of the active diluent.
Nine, UV varnish coating uneven, streaks and orange peel phenomenon
1, UV light oil viscosity is too high 2, coated anilox roller mesh is too thick (too much coating), the surface is not smooth 3, uneven coating pressure 4, UV light oil leveling poor
Solution: Reduce the viscosity of the varnish, reduce the amount of coating; adjust the pressure evenly; coating rollers should be finely polished; add bright leveling agent.
Ten, UV varnish adhesion is not good
1, printing ink surface crystallization 2, printing ink in the additives are not suitable 3, UV light oil itself adhesion is not enough 4, light curing conditions are not suitable
Solution: The printing process should consider the varnishing conditions in advance; the primer to enhance adhesion should be applied to the printed product.
Eleven, UV varnish thickening, gel phenomenon
1, UV light oil storage time is too long 2, UV light oil is not completely protected from light storage 3, UV light oil storage temperature is high
Solution: Pay attention to the effective use period of UV light oil and store it strictly away from light, and the storage temperature should be 5~25℃.
Twelve, the residual odor is large
1, UV light oil curing is not complete 2, UV light is not enough or UV lamp aging 3, UV light oil poor oxygen interference resistance 4, UV light oil non-reactive diluent added too much.
Solution: UV light oil curing must be thorough, and to strengthen ventilation, if necessary, replace the light oil varieties.UV LED curing machine curing light oil product effect real test.
