Food-grade silicone bracelet luminous coating process

The core of the luminous coating process for food-grade silicone bracelets lies in combining luminous powder with silicone materials to achieve a luminous effect. The following is a detailed introduction:

Raw material selection and processing

Silicone raw material: Silicone is a highly active adsorption material, processed from silicic acid gel through a series of procedures. It features high-temperature resistance, corrosion resistance, non-toxicity, and odorlessness, meeting food-grade standards and ensuring the safety of children wearing it.

Luminous powder: Luminous powder itself is non-radioactive. It has a short light exposure but a long luminous effect, and its luminous life can reach more than twenty years. Generally, after a short period of exposure to electric light or sunlight, the subsequent luminous time is usually within three hours, which is equivalent to absorbing energy and finally releasing it. This pattern conforms to the law of conservation of energy.

Raw material processing: Mix the luminous powder into the silicone material in a certain proportion, stir thoroughly and evenly to ensure that the luminous powder is evenly distributed in the silicone, so as to achieve a uniform luminous effect.

Forming vulcanization

Mold design: Precisely manufacture molds based on the design drawings to ensure the accuracy of the shape, size and details of the silicone bracelets, so that the produced products meet the expected quality requirements.

Molding process: Put the silicone raw material containing luminous powder into the mold and carry out molding vulcanization under high temperature and high pressure. During this process, the control of temperature and time is extremely crucial and needs to be precisely mastered to ensure that the silicone raw materials gradually solidify and take shape, forming a silicone bracelet with a luminous effect.

Post-treatment process

Surface treatment: After vulcanization, the surface of the silicone bracelet may not be smooth enough or have flaws. Surface treatment such as grinding and polishing is required to improve the appearance quality of the bracelet.

Trimming: Trim the bracelet, remove the excess parts, and ensure that the size and shape of the bracelet meet the design requirements.

Inspection: Conduct a strict inspection of the bracelet to check whether its luminous effect, appearance quality, dimensional accuracy, etc. meet the standards. For substandard products, they should be reworked or scrapped in a timely manner.

Optimization of luminous Effect (optional)

Colored glow-in-the-dark design: Besides the simple glow-in-the-dark design, you can also add colored glow-in-the-dark powder to create a variety of colored glow-in-the-dark designs, making a wristband have all kinds of colors gathered together, which is more eye-catching.

Selection of luminous powder types: Different luminous powders with various colors and brightness can be chosen according to your needs, such as high-temperature high-brightness blue luminous powder, green long afterglow luminous powder, blue-green luminous powder, etc., to achieve different luminous effects.
