Luminous printing operation flow injection

https://www.facebook.com/pages/Glow-in-the-dark-powder/ First, the method for injection molding technology
Epica long-lasting luminous powder for injection, the luminous material and plastic material ratio is usually about 2% to 10% (under normal circumstances is 25 kg plus one kilogram of the material inside the afterglow luminous paint), according to the color of the product depth, light color add less, pay more glow in the dark sandcolors principle may be. First, when the ingredients, first spread of oil added to the raw stir for a minute, then add the luminous material stir one minute, plus toner stirring two minutes, stirring time is not too long, it is worth noting that very sensitive and long-lasting luminous powder iron friction material will darken too long. Secondly, injection confidential clean, the temperature should be transferred to a minimum, can be injection molded, the material in the injection molding machine time not too long, to avoid burning, injection molding machines of different products, there are differences between the new and old machines machines, domestic machines and imported machines, which require debugging slowly resolved. Again, Epica luminous materials also have certain requirements, long-term STORING powder due to various reasons such as injection molding technology, injection molding machines, melting temperature of the material so may cause black, short-acting light-emitting materials (zinc sulfide luminous powder) in injection molding in terms of injection black areas show a little better. Stir before first injection luminous, not friction stir with iron, so luminous turn black, use a layer of plastic stir stick or cloth, so luminous works best!
Second, luminous with automatic extinction, STORING, luminous performance, absorbing all kinds of natural light (sunlight), lighting, etc.
? Visible 5-15 minutes, you can continue to light at night or in the glow in the dark sandmore than 8-15 hours, and can be infinitely recycled.
2. stable physical and chemical properties, strong environmental adaptability, long life. Can in outdoor or harsh environments, and can resist ultraviolet radiation, high temperature (+ 1000 ℃) and low temperature (under 1-20 ℃ in, the same black, not bad, good chemical resistance.
3. luminous product specifications: diameter (5um-200um) mesh (100 mesh -800 mesh) (1000 -2000 Head Head)
4. The use of luminous: not with opaque material mixed use, in order to avoid reducing its luminous efficacy. Must not contain heavy metals and calcium, diluent, adjuvant mix. Can not make a strong grinding, stirring Load method should be used.
5. luminous plastic injection, extrusion application notes:
● luminous with various types of plastic injection, extrusion, such as: PP, PE, PVC, PU, PS, ABS, TPR, EVA, nylon, acrylic and so on.
● When luminous direct injection, should be added the right amount of diffusion of the oil (white wax), the proliferation of pink slip agent additives, so luminous even better in combination with plastic, preferably using masterbatch, will be more evenly dispersed, masterbatch tablets before use must fully dry.
Third, the luminous Caution: play Epica luminous paint performance, must be complete and correct construction. Construction on the following considerations: the
(1) to understand the performance of luminous paint prescribed method of construction: if it is a professional construction time: We recommend spraying the polymer coated one to two agents on the ground floor and the completion of the film, so can enhance adhesion, weather resistance and paint life.
(2) do a complete surface treatment: surface treatment proper or not, has a great influence on the performance and life of the film, it is necessary to completely remove rust, grease and other foreign matter to be constructed and fully dried after brushing.
(3) should be fully luminous paint Stir: luminous paint pigment, a mixture of resin solution and Epica luminous afterglow of a long-term, from manufacture to use, there may be a period of time, but it is inevitable that the pigment was isolated and luminous of precipitation, Therefore, before using, stir.
(4) One of the brush thickness should not be too thick: once when the thickness of the brush if too thick, prone to effusion, wrinkles and other phenomena. So do the appropriate control, multi-layered coating to do the construction.
? (5) photoluminescent pigment than the major attention when using the mix.
(6) metal materials have a greater impact on the luminescent properties, should avoid contact with metal.
Most (7) luminescent pigment sparingly soluble in water, decomposed in acid, so the system can not be applied to water-soluble and acid system.
(8) according to your manufacturing process, select the appropriate size of the luminous pigment.
(9) should be stored in ventilated, dry environment, pay attention to moisture, failed once finished using luminescent pigment should note sealed.
(10) is usually a large
