Why does phosphorescent tape glow?

There are two principles of luminescence in the phosphorescent tape:
One is that the phosphorescent tape USES a natural mineral that can store light. When the outside world darkens, it releases some of the stored light naturally, creating a luminous effect.
The other is that the phosphorescent tape USES non-woven fabric as the raw material. After being irradiated by the uv lamp, it produces the effect of starting light.
Usually what we call the luminous principle is the first kind.
The fluorescence materials used today are mainly white powders of zinc sulfide or copper sulfide. When they are exposed to light, they absorb a small amount of energy, and when they leave the light, they emit a faint glow that is green.
Very little activator is often added to the fluorescene: 1 parts per million of cupric chloride and cupric nitrate increase brightness; Adding materials such as manganese chloride or silver nitrate can produce different colors of light.

Temperature change ink is also used in the Teapot

 Since ancient times " need a good pot of tea ," said one , photochromic masterbatch is a teapot for the top grade of tea utensils . Teapot territory of China , is the origin of the best Yixing . The Teapot culture, but also Chinese traditional culture can not be an integral part . Teapot is a practical daily life utensils for tea and tea drinking . Teapot in Yixing, Jiangsu origin , also known as Yixing teapot . Teapot making its long history and ancient and beautiful art form become a kind highly collectible collectibles and appreciate the value of art - ink temperature change .
Teapot , Jiangsu Yixing most prestigious. Began in the Northern photochromic sheets, flourished in the Ming and Qing dynasties , a modern prosperous during the peak period is unique in the history of purple , diversification celebrity men , technology and styling , more so purple added a mystery. Now Yixing purple clay teapot , purple crafts , purple discoloration Cicada , color kettle , purple vase , purple mural , purple flower pots , purple sculpture , purple and purple decorations tea sea . Have developed a unique style features complete .

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 .
