3D printing and Photoluminescent Rigid Sheet

Although the development of 3D printing technology is very fast, the biggest problem in 3D printing is that the finished product is monochrome, which undoubtedly limits the space of people's imagination. Recently, Photoluminescent Rigid Sheet STRATASYS announced the launch of the world's first color 3D printer, this printer can combine color printing and multi material 3D printing.

It is reported that the objet500 connex3 color material is much 3D printer uses a unique triple injection technology, which uses the three print head,
photoluminescent pigment can let three base material of liquid drop produced a variety of combinations, in order to achieve a variety of color printing effect.

The technology can be mixed almost all rigid, flexible and transparent colored material and color digital materials, through the three droplet aggregation of the basic material, disposable print out demand components.

The color principle of the product is similar to a 2D inkjet printer, the color of the material red, yellow, blue combination of vivid colors. These color material added STRATASYS widely polyjet photopolymer materials, fluorescent pigments manufacturer including multiple aspects of digital material rigidity, durability, transparency, and so on, by other high temperature material to simulate high temperature engineering plastics to produce standard color.

At present, this printer can print more than 700 kinds of materials, any other machines can not do the world. And this more than 700 kinds of material combination, can realize rubber, transparent, glow in dark sheets translucent, polypropylene and so many kinds of molding enterprise hope to adopt material.

Porous silicon photoluminescence (PL) quenching and recovery reasons

In the case of argon ion irradiation, irradiated porous silicon photoluminescence (PL) quenching occurs, and when the porous silicon after irradiation stored in the air, PL recovery will happen,  Photoluminescent Rigid Sheet  but the low strength of the final restoration in the luminous intensity of the original porous silicon. PL quenching of radiation due to the porous silicon surface defects, these defects as non-radiative recombination centers so that PL quenching occurs.

PL recovery and back key oxidized Si-H bond-related; in the case of nitrogen ion
irradiation, PL performance changes with argon ion irradiation is similar, but the strength of the recovery is stronger than the original PL porous silicon, which is the irradiation process Si-N bond formed about,  masterbatch production and in the process of irradiation of oxygen ions, oxygen ions are oxidized Si-H bonds is irradiated, the porous silicon surface shape.

The function and using method of IP consisting of Photoluminescent Rigid Sheet

IP is the medium of photography image transfer in CR system, it is composed of a supporting body, light induced light-emitting material and a protective layer, arranged in a special cartridge, Photoluminescent Rigid Sheet use method and ordinary film, photography only after not washing, sent directly to the image reading unit reading images.

There are two types of rigid and flexible laminates of the present IP, flexible plate is more common. The disadvantage is that the image reading is easy to cause scratches and rigid plate, glow in dark sheets only a few manufacturers can produce, it can effectively solve the problem of scratch.

Photography, IP in the fluorescent substance and through human X-ray signal corresponding reaction (one shot), the X-ray image like storage in the two-dimensional plane, photography after IP was sent to the image reader, image reading machine will to point the beam to it for full scan (secondary excitation), so that the memory from the luminescence of the X-ray signal, to read machine optical tube will be the collection and introduction of photomultiplier tubes, photomultiplier tube according to the intensity of the incident light sends out the corresponding Electronic, so as to change the optical signal into electrical signal, glow in the dark film and then send to the image processing workstation for digital processing of the signal.

IP can be reused, image reading after, IP was sent to a set of strong light irradiation, put the cleared all the latent image IP are then fed into the cassette to prepare for the next use. Can be reused 20000 times.

Effect of ion irradiation on the luminescence properties of porous silicon

Porous silicon can emit intense visible light at room temperature, Photoluminescent Rigid Sheet ,so it has great application prospect in the semiconductor lighting and photoelectric integration.

But when the porous silicon deposited in the air, the luminous intensity of porous silicon will be gradually weakened, and the instability of porous silicon light emitting porous silicon largest become an obstacle in the application process. This paper adopts a series of novel methods of surface treatment on Photoluminescence of porous silicon was improved after treatment, glow in the dark sand ,porous silicon luminescence intensity increased significantly. This paper studies the different active energy (800eV) effect of ion irradiation on the luminescence properties of porous silicon.

Photoluminescent pigment surface treatment

Using appropriate additives and processes for surface treatment luminescent pigment to disperse,photoluminescent pigment , water resistance, aging resistance and other performance indicators have certainly improved and enhanced, and the luminance of its specific surface area and fineness were no significant impact solve luminous paint in the production, application of the existing problems.

Luminous paint that absorbs sunlight during the day and night, self-luminous paint,Photoluminescent Tumbled Gravel , its applications are currently expanding. However, there are some problems in luminous paint production applications, such as occurs when added luminescent paint pigment agglomeration precipitation place a long time, brightness down and other issues that affect the further development and application of luminous paint.

Five kinds of use of luminous paint

Use of luminous paint has four kinds,

1. You can make use of luminous paint brush, roller, spray coating, knife coating, photoluminescent pigment curtain coating and other processes.

2. When luminous coating reaches a certain thickness, in order to obtain the ideal brightness, and therefore should be a minimum luminous coating 100-150um.

3. In the luminous white primer coating Below is a bottom can improve the luminous intensity.

4. In the light-emitting-clear coating to improve the coating gloss and weatherability.fluorescent pigments manufacturer

5. The viscosity of the coating can be adjusted according to the construction method, and before each use to mix evenly luminous paint
