Main Raw Materials:
Rare earth long-lasting afterglow night-light powder, polystyrene resin
1. Nightlight powder
is a high-tech self-luminous product made from rare earth metal elements activated alkaline earth aluminate and silicate. It can withstand temperatures of about 800 degrees. Its function is to absorb light and store light to emit light. It absorbs light in bright places (more than half an hour), and emits light in dark places. It has a strong ability to absorb short-wave visible light with a wavelength of less than 450 nanometers. By absorbing various natural or artificial light, it achieves the function of self-luminous in the dark state, and can be recycled. This luminous material has a high initial brightness of 2-3 hours, and the shoulder light curve is smooth. The afterglow duration can reach 8-10 hours. The afterglow luminous time and brightness of long afterglow night light powder are brighter than those of traditional zinc sulfide storage powder, and they have a faster absorption effect on sunlight and ultraviolet light. It can be used multiple times.
Poly(styrene) resin (see detailed information on Baidu Encyclopedia)
Polystyrene, abbreviated as PS, refers to a polymer made from styrene monomers through free radical polymerization. In Japanese, it is known as polystyrene. It is an odorless and transparent thermoplastic plastic with a glass transition temperature above 100°C, making it often used to create various disposable containers that can withstand boiling water and single-use foam food boxes. Regular polystyrene resin is an amorphous high molecular polymer with random arrangements of large-volume benzene rings in its side chains, which determine the physical and chemical properties of polystyrene, such as high transparency, high rigidity, high glass transition temperature, and brittleness. Expandable polystyrene is made by immersing low-boiling physical foam agents in regular polystyrene, which bubbles up during processing and is used to make foam plastic products. High-impact polystyrene is a copolymer of styrene and butadiene, with butadiene as the dispersed phase, which improves the material's impact strength, but the product is not transparent. Isotactic polystyrene is an isomeric structure produced using metallocene catalysts, and is a new variety of polystyrene with good performance, which belongs to engineering plastics.
 
Packing Method:
Bulk (25KG per bag), bag (1000G, 500G, 100G per small bag), boxed. According to customer requirements, we can apply logos, barcodes, etc. on the packaging...
Please indicate the color when shipping. It can be mixed color or clear color.
The night-light stones produced by our company are exported to the United States, Australia, Russia, and various countries in Europe, and are deeply favored by foreign customers.
Product dimensions (the following dimensions and weights are reference values)
Size: About 2CM
Weight: About 2.2 grams
Due to the irregular shape of the stones, the above dimensions are only estimated values. The weight is the sample's weight, and the data are for reference only. The shape of the stones will be shipped randomly when shipping.
 
 
Luminescence principle:
 
The principle of night-light stones is that after being stimulated by visible light such as sunlight or artificial light, they absorb and store energy. They can then emit light naturally in the dark for a long time. The product can be reused repeatedly by absorbing and emitting light. The service life is long.
