Features luminous quality , non-toxic harmless

It is because of the characteristics of high-quality non-toxic luminous powder makes the whole process does not require any other chemical raw materials, the real environmental pollution . Through the luminous technology to optimize the process , luminous masterbatch process is also very simple, usually twenty-three hours to master all the processes. As an innovative product , moonlight ice painting to fill a number of gaps in the industry , the rapid spread of a new generation of environmentally friendly applications.
Other eye-catching and luminous products due to too affected by the wavelength of the night waking unintentional glance , it is no longer difficult to sleep. The light emitted by luminous products like moonlight , soft eye-catching but not stimulate human vision, so as to avoid this situation. Compared to other masterbatch glow in dark, products with luminous at night not only to indicate the text , but can also display images. Instructions to identify more humane , and thus greatly increase the scope of use . Not only for business and home office spaces , but also can be widely used hotel , KTV and other entertainment fields . Not only functional, but also more grades .

Identification of the invoice with the temperature change ink

Temperature change ink ! As the name suggests , the ink temperature change as the temperature changes that will produce a color change , because it is this characteristic , it is used in a number of special items above anti-counterfeiting technology , powdered paint pigments version of the invoice at the Inland Revenue Department in Guangdong it is applied to the temperature change ink !
It was reported that "Guangdong Local Taxation generic fixed invoices " using a special ink temperature change IRD printing "LT" this pattern . At room temperature, this pattern was emerald green , but if you rub with your fingers jammed after heating , driveway stone will change to yellow , then drop back to room temperature, the temperature , but also color changes back to the original emerald green . Due to some kind of temperature change ink IRD -specific, so the move can effectively identify the authenticity of the invoice !

Adding as little as possible

​Long afterglow luminous use:
1 . Injection : press the proportion that good luminous body , adding an appropriate amount of paraffin oil ( diffusion oil can ) , into a paste, then pour weighed glow in the dark film compound can be produced . There can be injection molded material : pp, pe, pvc, pu, ps, abs, tpr, eva, pmma, nylon. The more transparent plastic  material , light the better , as far as possible with fluorescent toner toner , adding as little as possible ,
2 tone ink : that good luminous materials, transparent varnish, related auxiliaries stir evenly ( What varnish, what additives are different ) .
Use long-lasting afterglow luminous powder ratio:
1 . Injection : It is recommended 4-10 % , often 5-6 % , glow in the dark dye according to customer requirements .
8% brightness with good meal , the proportion of low concentration powder brightness.
2 . Transfer ink: recommended 40-60 % , often 50%.       

What are the characteristics of temperature change ink

Temperature change ink known as thermochromic ink , showing temperature sensitive ink or ink . Temperature change ink into three categories: the display a specific color temperature , the color disappears upon heating becomes colorless glow in the dark immediately restore the original color , because reversible change process , referred to as " inversion variable message color ink " ; Show colorless at room temperature, after heating into another color , then restore the original cooling colorless , photoluminescent films the change process reversible , referred to as" inversion hair color ink " ; ink display color at room temperature , after heating into another color , because the reversible change process referred to as " inversion variable color ink transfer ". 

The organic photochromic material

Our organic photochromic materials began in the 1980s . Nankai University graduation certificate security seal , is the oldest university diploma gravels for driveway application security is the first application of this technology in the security identification technology. Then the technology have been used in garment decoration , inks , paints, plastics , and other fields , to produce color clothing, color sandals, color plastic , color glasses , etc. ; covert military camouflage material also successfully Photoluminescent pigment, such as gradient color chameleon camouflage applications have mature, discolored material, especially by consumers in the clothing industry .

luminous and phosphor What is the difference

First, the main component of Epica and features luminous powder ;
1 luminous Description Material composition mixture 4SrO.7AL2O3: Eu (Eu as rare earth elements ) .
2 main non-toxic non-radioactive luminous , no burning, no explosion, free of heavy metals or other harmful chemicals .
3 luminous with a very stable gravel for gardens chemical properties , strong adaptability to environment and extremely long service life , luminous effect can be achieved using the longest 20 years . Luminous density ρ ≈ 3.6gcm3 7. Maintain good stability at -60 ℃ -600 ℃ condition .
4 luminous luminescent time is short, high brightness, long afterglow time , rich color varieties , colors and more .
5 can be used as an additive or luminous pigment. glow in the dark dyes in a variety of transparent or translucent medium, such as paint , oil, black, plastic , rubber stamp glass , ceramics, chemical materials , to achieve self-luminous function media should exhibit good low lighting instructions and decorative landscaping effect.

luminous production process

Features : Unlike the luminous phosphors , which non-radioactive , light long short but luminous efficiency , low cost , colorful. Second, the equipment: electric furnace , crucible , ball mill, drying equipment. Third, the formula : red luminous : 55 grams decorative aggregate , 40 g of magnesium sulfate , lithium phosphate, 2 g , 3 g of copper nitrate blue luminous : 63 g of calcium sulfide , sodium sulfate, 5 g , 5 g of potassium sulfate , strontium sulfate 10 g, 6 g of sodium chloride , 1 g of silver nitrate , 10 g magnesium sulfate . Purple luminous powder : 63 g calcium sulfide , magnesium sulfate 26 g , 10 g sodium sulfide , strontium nitrate 1 g . Green luminous powder : 55 g calcium sulfide , potassium sulfide 1 g , 10 g sodium sulfide , barium nitrate 12 g , 13 g of indium nitrate . Luminous yellow : barium sulfide 55 g , 40 g magnesium sulfate , aluminum sulfide 2 g , 3 g of potassium nitrate . Fourth, Crafts: after with a good raw material, the temperature on the crucible furnace heating , raw material in the pot , glow in the dark stone, mix the raw materials directly on the burning furnace , the temperature is 133 degrees , burning 50 minutes after hand -colored pick insufficiency impurities, and then placed in the cooked raw mill ground into fine powder and then soaked in water for precipitation to remove water, the sink in the powder can be placed in the drying oven . Fifth, use : put a colorless transparent plexiglass Two bananas dissolved in water . After adding 72 hours to the amount of luminous paint on watches, clocks , instruments and crafts .
