Luminous ink, paint preparation and use methods

When using luminous powder to mix paint and ink, in order to achieve the best luminous effect, the choice of paint or ink is very important. Choice of paint and ink: Has colorless and transparent, good light transmittance, especially good uv transmittance (i.e. no uv resistance). Varnish of organic solvent series. Resistant to light and weather and stable chemical properties. The surface adhesion of products to be painted is good (depending on the base material). In accordance with the above characteristics of paint or...

Photoluminescent pigment and polyvinyl chloride resin formulation

Polyvinyl chloride (PVC) 16-18% plus ring has 0%, hot melt after as puree. Wataru first ring B into the container, then add PVC. And with the added with partners. Upon completion of the addition, this container does not exceed 50 ℃ in hot water and dissolved with stirring 15 minutes, until the PVC fully dissolved, which is puree puree Photoluminescent pigment30% plus 100% stir for 30 minutes Become a luminous plasma, the other plus glow in dark powder varnish...

Synthesis method of long afterglow materials

High temperature solid phase reaction method Long afterglow which was prepared by using high temperature solid instead should process is: according to the calculation of the mole ratio of says take spectrum pure co: A120, sr - and Eu203 raw material, and after a certain amount of canadians flux blending fine grinding, first by 1500 ℃ calcination 3 hours, then in the reduction of gas and 1200 ℃ 1400 ℃ roasting 2 one 4 hours, only made larger phosphor,...

Instructions for the use of long-acting luminous powder, technical indicators

Long-term luminous powder soil type belong to alkaline earth aluminate long afterglow luminescence materials, components can be expressed as: Al2O3 · (Sr, Mg, Ca) O: (Eu, La, Dy) B, can be in the sun or light absorbance 5-20 minutes later, will absorb the light energy stored in the crystal lattice, after can convert the energy into light energy in the dark and light, which can effectively sustained glow (luminescence brightness is more than 10 MCD/m2) to 8 to 10...

Examples and formulations of application of luminous powder in coatings and inks

May be mixed with a variety of transparent resin coatings and ink to make the glow in dark paint or inks. Such resins include acrylic resins, urethane resins, epoxy resins, amino resins, polyvinyl butyral resins, polyamide resins, etc., in coatings used in a proportion of 10% -50%, the proportion of the ink is 30% to 60% as well, the above-mentioned resin is dissolved with an appropriate solvent, adding luminescent pigment, and then adding a suitable anti-settling agents, antifoaming agents,...
