Led Slap Watch Silicone strap
We are no stranger to rubber straps. Silicone, as the new favorite of strap material, often appears in sports watches and diving watches. On the surface, this strap is very similar to the traditional rubber strap, but it seems to be different.
Silica gel is a huge family, divided into two major families of inorganic silica gel and organic silica gel. Inorganic silica gel is a highly active adsorption material, usually made by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid foaming. Its main component is silicon dioxide, which is structured like a sponge. The interconnected pores form a capillary pore adsorption system with a large surface area, which can adsorb and condense water vapor equivalent to 40% of its own weight, so it is mostly used as a desiccant. Although inorganic silica gel is not used to make watch bands, it is often used in the care of watches. As long as the watch with silicone particles and water is put in a closed container and removed after a few hours, the water in the watch All will disappear.
Our daily use is more organic silicone, which is divided into silicone rubber, silicone resin and silicone oil, which is a special rubber in synthetic rubber. The material often used in watch bands is a small branch of the silicone family, namely room temperature vulcanized silicone (RTV) in silicone rubber.
The raw materials for producing silicone rubber are silicon powder, methanol and hydrochloric acid. Silicon rubber can be finally obtained through a series of complicated chemical processes. This silicone rubber is also called "liquid silica gel" because of its low molecular weight and liquid state at room temperature. After mixing the cross-linking agent and platinum catalyst in the liquid silica gel, and then injecting it into the model, it can be cured after curing for a period of time. Increase response speed). And form the final product. Adding different additives can make silica gel materials have different specific gravity, hardness, strength, color and texture.
Led Slap Watch Noctilucent material principle
The phenomenon of material luminescence is generally divided into two categories: one is that the material is heated to generate heat radiation and emit light; the other is that the material is excited to absorb energy and then transition to an excited state (unstable state) and then return to the ground state. Releases energy. The use of fluorescent coatings on watches uses the second type of principle, that is, fluorescent materials emit light when excited.
Traditional fluorescent coating materials can be divided into two types: self-luminous and light-storing. Self-luminous fluorescent agents mostly rely on self-carrying traces of radioactive substances to release light to excite the fluorescent agent to emit light. The light-storing fluorescent agent basically does not contain radioactive materials, but it needs to absorb and store sufficient external light in advance to transfer its electrons from a low energy level to a high energy level and store it. When the surrounding environment is dark, it gradually releases the absorbed energy gradually. At this time, the electrons transition from a high energy level to a low energy level, and the phosphor starts to emit light. Since the light-storing type itself does not carry ray-excitation materials, the persistence of afterglow is temporarily inferior to that of the self-emitting type.
