I. Intruduction

Shandong lunbo luminous products co.,ltd has been leading the way of applying the photoluminescent pigment to glaze to make photoluminescent glaze which can be widely used in the production of ceramic floor tiles,ceramic internal wall tiles and enamel signs and give luminous products excellent indicating and beautifying effect.

The photoluminescent glaze is composed of basic glaze,photoluminescent pigment as well as little additives and can be used directly to produce luminous products after complete blend.It can be applied to artistic tiles of internal wall,indication tiles,household ceramics as well as glass utensils.

Note: The thickness of the photoluminescent glaze layer is suggested 0.2-0.4mm.

III.Usage

Luminous Enamel Glaze
Photoluminescent enamel glaze had better be doped on the surface of the fired white enamel glaze layer to form the luminescent patterns. The doping and firing technologies of white enamel layer are like those of traditional white enamel.
1. Mix the PL enamel glaze with water (the weight ratio is 1:0.5-0.6) in the ball milling pot for 5 minutes to get glaze slurry.
2. Dope glaze slurry on the surface of the fired white glaze layer to get luminous layer, the thickness of this luminous layer is 400-500μm.
3. Dry it.
4. Fired 2-4 minutes at 800-850℃, luminous enamel product is got.
5.In order to obtain more smooth surface, a layer of thin transparent glaze can be doped on the luminous glaze layer.
6. Luminous glaze can also be mixed with certain amount of screen-printing ink to form luminous patterns through screen-print technology.

SUGGESTIONS
1. Do not grind the PL pigment with metal material, otherwise the luminous effect will be affected.
2. Add 1-2%(by weight) of baste to increase the fluidity and suspension of glaze, if you find deposition during usage.
3. Using TCB-35 transparent enamel glaze manufactured by our company, you can get better effect.

Luminous Ceramic Glaze
Adopt different technological steps according to different luminous ceramic products.

Luminous internal wall glaze tile
1. Ball mill TGB-45M series PL ceramic glaze with water (the weight ratio is 1:0.6-0.7) in ball milling machine for 20 minutes to get the glaze slurry.
2. To form a layer of luminescent glaze 200-400μm by spraying, spraying and pouring method.
3. Dry it.
4. Fired 35-50 minutes at 1000-1080℃, luminous internal wall glaze tile is got.

Luminous floor tile(pattern tile)
1. Mixing TGB-45H series luminous ceramic glaze with certain amount of screen-printing oil can get the screen-printing slurry.
2. Screen print luminous glaze slurry on the unfired floor tile's white glaze, then get luminous pattern.
3. Pour a layer of transparent glaze on the surface of the pattern.
4. Fired 35-45 minutes at 1100-1180℃, luminous design tile product is got.

Luminous internal wall design tile (fired for three times)
1. Mixing TGB-45L series luminous ceramic glaze with certain amount of screen-printing oil can get the screen-printing slurry.
2. Screen print luminous design on the surface of the fired white internal wall glaze tile.
3. Pile transparent dry glaze powder on the luminous design with screen.
4. Fired 40-50 minutes at 900-1000℃, internal wall tile with protuberant design is got.

SUGGESTIONS
1. Do not grind the PL pigment with metal material, otherwise the luminous effect will be affected.
2. If you find deposition during using, add 2%(weight) of baste to increase the fluidity of glaze.
3. You had better adopt suited transparent glaze produced by our company when producing luminous tile.
