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
https://www.facebook.com/pages/Glow-in-the-dark/ powder particle size, brightness better. However, we recommend, first of all according to your manufacturing process, select the appropriate size of the luminescent pigment

Leak phosphor mainly be used in any industry

https://www.facebook.com/pages/Glow-in-the-dark-material/ First, is mainly used to bag leak detection, leak detection equipment, pipeline leaks leak, leak detection circuit is smooth, the machine detects whether the line is broken.
Second, the phosphor good heat resistance: maximum temperature of 600amp # 176C, suitable for high-temperature processing of various treatments. Good solvent resistance, acid, alkali, high stability.
Third, the phosphor of plastic injection and extrusion applications:
A. applicable to all kinds of plastics such as PE, PS, PP, ABS, acrylic, urea, melamine, polyester, resin, the fluorescent color.

B. recommended dosage of 0.05% to 0.5%, typically 0.05-0.1%

C. Mixture should add a certain percentage of additives to enhance its stability and oxidation resistance.

Fourth, the phosphor coating and screen printing ink of the application:

A. inorganic
https://www.facebook.com/pages/Glowing-rocks/ are dispersed in the paint and ink, does not dissolve in the paint and ink. Phosphor is dissolved therein.

B. can be used in oil and water-based coatings and inks it. Neutral or alkaline transparent resin (pH 5-7 mass most applicable) should be used. Recommended dosage of 2% to 3%

C. apply to all types of printing, including screen printing, gravure and letterpress printing.

D. Background printing is recommended to use a white or light-colored, color change can improve the degree of difference.

E can be mixed with dyes or pigments, with a greater variety of color variations.

F. printed material is different, you should choose a suitable substrate of paint or ink.

Five, offset or gravure colorless fluorescent ink should note the following:1. The transfer roller and the plate needs to be cleaned, using a new ink roller is more ideal, otherwise, a very small amount of colored ink also has the potential to colorless fluorescent colored ink, affect the printing quality of appearance.
2. Different papers have different effects on the colorless fluorescent colors. Since most of the surface of the paper have been processed fluorescent whitening agent, a fluorescent whitening agent in the ultraviolet lamp emits blue color light, and therefore, in the absence of brighteners paper (bond paper) sheet containing whitening agent (such as plain paper), the effect of color colorless fluorescent ink, there are some differences. Need to mention that it is precisely because of this reason, too colorless fluorescent blue ink for paper containing strong fluorescent brighteners. Otherwise, the blue fluorescence will "drown" in the blue whitener.
3. Such printing inks can be printed on non-patterned part, can also be printed on the pattern. To highlight the fluorescent effect, usually printed on the outermost layer of the pattern.

The use of Fluorescent paint

A. Demand for covering large area of flat paint do not recommend the use of spraying (air spray gun is better).

B. When using an empty spray can be used directly without dilution or viscosity depending on the needs of spray consider to add diluent (with BAC or toluene may be), the amount of diluent should be added to ≦ 5% is appropriate, in order to avoid reducing their cover force.

C. luminous paint department genus (oily self-dry paint), containing polar solvent blend, general water-based paint and elastic coating paint erosion of fear in doubt, please use the former to be prudent in a small area or hidden at the first trial.

1. Clean the coated surface coating should be preceded, if uneven first renovation of the coated surface smooth; Judai it completely dry, and then

Pre-spray acrylic series white (plain) primer better.

2. In order to better STORING luminous paint is recommended to be sure before spraying spraying acrylic series white (plain) primer to the bottom.

3. When the spray primer is completely dry, then spray paint spraying luminous Please drape surface distance is 15-25 cm is appropriate, spray a thin layer of about 5-10 minutes or so until then spray the second track.

4. Each channel between 5-10 minutes spraying time is appropriate, should be sprayed at least three of the minimum benchmark, even after spraying depending on the circumstances; the fourth channel can be combined with spraying or more, with thickening of the paint film thickness of its STORING stronger (ie, better brightness at night).

5. luminous paint (touch dry time is about 15-20 minutes), after the completion of the visual needs spraying lacquer spray again, to make the surface more beautiful luminous paint more durable use of time.

Brushing with:

A. Pifu small area of the object is recommended brushing (using special paint brush).

B. When using the brush can be used directly without dilution or brushing thinner viscosity increases proportionally demand (with BAC or toluene may be), the amount of diluent should be added to ≦ 5% is appropriate in order to avoid reducing their opacity.

C. luminous paint are the property of (oil since dry spray / painting), containing polar solvent blend of general water-based paint, paint elastic coating erosion of fear in doubt, please use the former to be prudent in small area or shelter first trial.

1. Brushing should be preceded by cleaning the surface of the coating, such as uneven first renovation of the drape surface smooth Judai its completely dry, then spray acrylic pre-series white (plain) primer better.

2. In order to make better suggestions STORING luminous paint before brushing Always spray acrylic series white (plain) primer to the bottom.

3. After spraying or brushing until the primer is completely dry, then brushing luminous paint, please adopt accomplished in the same direction when brushing coating material

A thick coating operation, wait 15-20 minutes until their surface slightly after drying in the same manner as in the aforementioned second channel operations.

4. Do not over brush brushing construction under way or about to move back and forth brushing to avoid wandering produce luminous dispersed unevenly, leading to seriously affect their ability STORING.

5. Road brushing each interval to 15-20 minutes is appropriate, recommend brushing at least four cases of uniform minimum benchmark apparent after brushing it can be added a fifth channel or more, with the thickening of the film thickness STORING its stronger (ie, better brightness at night).

6. luminous paint (touch dry time is about 20-30 minutes), after the completion of the visual needs brushing or spraying on again brushing lacquer, to make the surface more beautiful Fluorescent paint more durable use of time.

Fluorescent paint Construction: luminous paint brush to go through after the formation of the film in order to function. Therefore, to fully dry.
