About reflective powder |
|
Other
name:reflective glass micro beads, reflective pigment, glass microsphere.
Refractive
Powder made of a glass-based material from production, the main component of
SiO2, CaO, Na2O, TiO2 and BaO like. The product can be directly added to the
coating or resin, the product has a return reflective effect, it can be used on
a variety of surfaces of complex shapes. It is a production of reflective
fabric, reflective film, reflective paint, reflective signs, advertising
materials, clothing materials, standards stadium runway, shoes, bags, land and
air rescue supplies and other new light functional composites core materials. |

Reflective
principle |
|
When the
light shines at the bead surface, due to the high refraction beads while
concentrating on a particular focus of the reflective layer beads, reflective
layer and the light reflected back through the transparent microspheres to a
nearby light source, it can be seen in the light source to a very bright
reflected light. Depending on the complexity of the optical formula is
calculated, when the bead refractive index greater than 1.9 or more, to form a
good return reflective effect. Reflective powder is a production of reflective
cloth, reflective leather, reflective film, reflective paint, and other new
luminous functional composites core element having return characteristics of
reflective and resulting strong reflection effect.

Application |
|
Widely
used in screen printing (can be printed, printing printed trademark of a
class), making reflective paint, reflective paint, reflective fabric,
reflective tape, reflective film and all kinds of reflective fabric,
reflective signs,
Core
material reflective logo, advertising materials, clothing materials, standard
stadium runway, shoes, hats, bags, land and air rescue supplies and other new
optical functional composite materials, it has reflective properties of the
regression and the resulting strong retro-reflective effect, no external power
supply, can be widely used in roads, ports, mining, fire and other fields, as
a safety flags, greatly enhance the user's safety and reliability. |

Use
method |
|
Use
one: screen printing method
A
water-based screen printing method: reflective powder reflective directly
added to the aqueous slurry, adding appropriate additives to enhance fastness,
tune evenly printing, printing.
Water-based
screen printing method two: reflective powder directly into the transparent
water-based ink, plus 2% of water-based special effects catalyst evenly tone
printing, printing. (This method is better)
Water-based
screen printing method three: reflective powder slurry directly into
transparent, appropriate to add additives to enhance fastness, tune evenly
printing, printing.
Oily
screen printing method one: reflective powder directly into the varnish, even
tone, appropriate to add additives to enhance fastness, you can print,
printing. (This method is better)
Oily
Screen Act II: reflective powder directly into the ink, made of reflective
ink, silk screen or brush onto fabric or other items.
Oily
screen printing method three: first primer topcoat reflective printing paste
--- --- drying curing paste printing, printing thinner layer thickness to 30
microns to 50 microns is appropriate to ensure that the reflective powder can
and a half. exposed on the surface, to produce reflective effect.
According
to use, the use of thickness ranging from particle size, to obtain a variety
of reflective effect. (Particle size range, reflecting the better)
Use
the above method, simple operation, easy to master.
Use
two: spraying
1
first reflective paint spray primer, to be reflective paint dry, then
spray-reflective finish. If the cement surface construction, the proposed
two-reflective spray paint better.
2
recommends using W-71-type gun (nozzle ¢ 1.50 mm) using a spray gun pressure
primer about 2.0Kg / cm2, paint spray gun pressure around 3.0kg / cm2.
3.
guns and surface construction need to keep 18cm, gun angle 45 °, paint a thin
film to have obtained good results. For unknown substrate, a small area prior
to trial
4
Do not rain and fog in the snow and other inclement weather construction, will
affect fastness. |
|
Notice |
|
Before
1. construction surface to be cleaned, the surface free of grease and dry.
Reflective
and reflective paint primer must be stirred before 2 construction uniform;
painting process to keep stirring to prevent reflective powder precipitation.
Reflective
pulp preparation: According to how much amount will be transferred into a
paste with a solvent (cyclohexanone) the reflective powder weighing, and then
added to the transparent printing paste, adjusting uniform use. When printing,
printing thinner layer thickness to 30 microns to 50 microns is appropriate to
ensure that the powder can Banlu reflective surface to produce reflective
effect. According to use, the use of thickness ranging from particle size, to
obtain a variety of reflective effect. (Particle size range, reflecting the
better). Add the amount depending on how many add reflective brightness.
The
above technical parameters, the practical application of summary from various
industries, for reference only, without any legal basis. Make each user before
use, must themselves first test proofing before production confirmation, or
peril. |
