The role of luminous painting:

Brush the adjusted luminous paste (not glow in the dark paint) on decorative items such as signboards, jewelry, scrolls, crafts, etc., and can emit light at night, and the ability to emit light is permanent (non-toxic and harmless to the human body).

With the improvement of people’s aesthetic concept, the technology of luminous painting will become more and more popular. Therefore, opening a luminous craft factory will have great development prospects. The production technology of luminous painting is very simple. Except for purchasing several chemical raw materials, basically, no equipment is needed.

The technical formula for making a luminous painting:

1, 16-18% of polyvinyl chloride (PVC), 70% of cyclopentyl ketone, after heating and melting into a raw pulp. Pour cyclo-ethyl ketone into the container, add PVC, and stir. After stirring, place the container in hot water below 50 ° C and continue stirring for five minutes. Add 30% of glow in the dark powder to 100% virgin pulp, continue stirring, and let stand for three minutes.

2, 7 grams of PVC, and 68 grams of cyclopentyl ketone were made according to the above steps. Add 25 grams of luminous powder to the original pulp and stir. The luminous pulp is completed.

Precautions:

  1. Regardless of whether it is printing or painting, we must pay attention to continuity and integrity. We must complete the production of the group at one time, and we cannot brush it repeatedly.
  2. When making the original pulp, the water temperature should not exceed 65 ° C and cannot be lower than 48 ° C.
  3. For winter construction, use PVC more to increase the viscosity. In summer construction, use cyclopentyl ketone to reduce viscosity.
  4. Before production, experiments should be conducted to find the best raw material ratio.
