Glowing powder is a powder material that can glow in the dark, also known as luminous powder, glow in the dark powder, phosphorescent pigment, or strontium aluminate powder. It is usually made of rare earth elements, zinc, aluminum and other materials, which can absorb energy when exposed to light, and then release light in dark places.

Today, we mainly discuss a topic that users are most concerned about, "Water-based glowing powder Flocculation".

First, during the long-term storage of the emulsion, the collision between latex particles will occur due to Brownian motion, resulting in emulsion coagulation. At the same time, due to the effect of gravity, the latex particles will also settle or rise to form a coacervate. No matter how high the stability of the emulsion is, it is inevitable to form irreversible aggregates during long-term storage to break the emulsion.

Simultaneous freezing and thawing can affect the stability of the emulsion.

This type of flocculation is a physical change and will not lead to an increase in the pH of the system.

Second, a certain substance in the system destroys the waterproof layer of the glowing powder, causing a chemical reaction of the glowing powder. The acrylic resin changes from small molecules to large molecules, and it will stick together with the powder. The powder precipitates and wraps the macromolecules together to form a solid. and blocky. At the same time, due to the reaction to produce aluminum hydroxide, the pH value will increase significantly.

Warn: The product after flocculation is irreversible. The molecular weight becomes larger, and then polymerized after dehydration. It is difficult to return to the original small molecule after polymerization.

Inventory powder detection method:

1. Take the orange glowing powder and yellow-green glowing powder in stock

2. Adjust the lotion in advance

3. Yellow-green glowing powder mixed with lotion

4. Orange Glow Powder Mixed with Lotion

5. After mixing 50% of the yellow-green and orange powders with the emulsion, do a PH test and a viscosity test, seal it and put it in 50-60 degree warm water (or in an oven)

After 12~13 days, check the pH and viscosity changes. It is recommended to use an electronic pH value tester.

Result analysis:

1. If the viscosity rises but the pH does not change, there may be a problem with the emulsion system. Suggestion: You can adjust the pH value of the emulsion to 6.5 to 7, and test again

2. If the PH value rises, the viscosity rises, and the glowing powder is hydrolyzed, then this batch of goods cannot be used

Suggestion: You can mix each additive with the glowing powder separately, and then observe the change in pH value to determine which additive reacts with the glowing powder, and then adjust the additive.
