Outdoor Waterproof Free Bending Easy Fixing No Glue Flex LED Neon Tube

Lead glass tubes (also known as red lead glass tubes) have better thermal, mechanical, electrical, chemical stability, vacuum, and optical properties than sodium glass. Their weather resistance and service life greatly exceed that of sodium glass. Most of these lead glass tubes are commonly used internationally, with a usage rate of about 20-30% in China. For manufacturers who pursue good quality, users choose lead tubes to make neon lights. Lead glass is divided into heavy lead glass, medium lead glass, and light lead glass based on its lead content.According to the materials used for coating fluorescent powder inside neon tubes: ① Most of the neon tubes used are sprayed with "ordinary fluorescent powder", which is relatively cheap and can generally meet the requirements of various colors. ② The "three primary colors" fluorescent powder, also known as rare earth fluorescent powder, has better brightness, chromaticity, and freshness compared to ordinary fluorescent powder.

Spray a mixture of alcohol and ketone soluble fluorescent powder onto the inner wall of the lamp tube with water, allowing it to dry naturally. Glue coating involves spraying a mixture of glue and fluorescent powder, and then drying it in an oven. Its viscosity and fastness are greatly superior to those of water coated powder tubes. Most advanced countries use three primary colors of lead coated glass tubes to produce neon lights, and some manufacturers in China have already used this type of neon tube.
