Luminous and luminous signs luminous paint production technology and methods fluorescent colored plastic paint factory specializing in the production of long-term environmentally friendly injection molding luminous, luminous glass, ceramics luminous, leather dedicated special luminous powder luminous toys, crafts special luminous . The large wholesale sales of luminous, fluorescent, fluorescent pink, luminous paint luminous paint production technology by Yiu Tak Hing Technology highlight the long-term production of environmentally friendly Afterglow (), resins, solvents and additives by a certain percentage by special processing technology made. Each component determines the performance of luminous paint, simply stated as follows: 1 luminous powder luminous powder. Resin and the resin should be chosen varnish has good transparency, and because long-term luminescent pigment weakly basic substance, so the resin is preferably neutral or weakly alkaline, if the aqueous resin aqueous coating, luminous paint the need for surface water treatment. The resin can be selected and varnishes varieties: epoxy resin (e440), polyurethane resin (or varnish), amino varnish, polyester resin, acrylic resin, hydroxyl acrylic resin, acrylic urethane varnish (two-component), light color alcohol acid varnish, fluorocarbon resin, etc. 2 Select luminous paint additives in the long-term primary dispersant additives, anti-settling agent composition, heavy metal compounds can not be used as an additive. 3. luminescent pigment can be used alkaline earth aluminate, silicate, zinc sulfide system, and the amount is generally 15 to 50% of the production process of the preparation of paint you should use a glass or enamel container type, particle size of the luminescent material as low as possible, preparation of coatings, do not be abrasive, high-speed stirring method should be used, the relative weight of the light-emitting material is 3.6 to 4.0, when it is easy to paint formulated to sink through the use of anti-settling agent, can improve the shelf life of luminous paint. Screen LED signs, LED signs are signs precautions need to use light-emitting ink, luminescent ink used in the sign industry manufacturers are generally used according to their intended use and signage products themselves formulated to obtain the best results and economy costs. Usually adding a certain proportion of the common transparent ink luminescent material by simple mixing process can be made use of light-emitting ink, the ink if stored for a period of time sufficient to facilitate wetting luminescent material, the resulting print product surface smoothness will be better. The specific choice of transparent printing inks and substrates to be concerned, simply choose the appropriate application of transparent ink to the substrate. Luminous powder luminous powder luminous powder luminous powder long afterglow photoluminescent pigment amount of long-term environmental protection: generally 30-50% of the total (light-emitting material and a transparent ink 1: 1 to 1: 2) to determine the brightness of the light emitting according to print requirements The amount of pigment. The content of the ink, the higher its printed products with brightness, longer lighting time. Processed light-emitting ink viscosity at 300 ~ 500pa? S about, in print. , It should control the printing speed, ink viscosity with thinner to adjust to meet the printing requirements for screen printing patterns using light-emitting ink, when identified, are generally choose 200 mesh polyester net, to obtain the best possible lighting effects a large selection of high-brightness light-emitting pigment particles (such as gl-2 sl-2) may be used from 80 to 100 mesh screen printing. Light-emitting ink is preferably printed on white base, use of the underlying reflective effect increased emission luminance printed pattern or logo and afterglow time. If the substrate is not white or light-colored, with white or light-colored require screen printing ink obtained above the substrate, the thickness of 0.1 ~ 1.0mm. Printing luminescent ink coating thickness control at 130 to 150μm, luminous best, such as 80-mesh screen printing twice, you can achieve this thickness. General signs and other requirements in the areas of lighting effects better, more use of 80 to 100 mesh screen, although to get better lighting effects, but less apparent effect printing, the surface is rough, sometimes need to surface again 160 mesh screen printing over smaller (eg 8c-a) products are better surface smoothing effect, the brightness can be guaranteed, but the process is more complex, needs to consider factors such as cost effectiveness.
