We are no strangers to rubber straps. As the new favorite of the strap material, silica gel often appears in sports watches and diving watches. On the surface, this strap looks similar to a traditional rubber strap, but there seem to be differences. Silica gel is a huge family, divided into two major families: inorganic silica gel and organic silica gel. Inorganic silica gel is a highly active adsorption material, usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. Its main ingredient is silica, which is structured like a sponge. The interconnected pores form a capillary adsorption system with a huge surface area, which can absorb and condense water vapor equivalent to 40% of its own weight, so it is mostly used in desiccants. Although inorganic silica gel is not used to make watch straps, it is often used in the care of watches---as long as the silica gel particles and the watch with accumulated water are placed in an airtight container, and taken out after a few hours, the accumulated water in the watch will be eliminated. will all disappear. We use more silicone in our daily life. It is divided into silicone rubber, silicone resin and silicone oil. It is a special kind of rubber in synthetic rubber. The material commonly used in watch bands is a small branch of the silicone family, namely room temperature vulcanized silicone rubber (RTV) in silicone rubber. The raw materials for producing silicone rubber are silicon powder, methanol and hydrochloric acid. Through a series of complex chemical processes, silicone rubber can be finally obtained. This silicone rubber is also called "liquid silica gel" because of its low molecular weight and liquid state at room temperature. After mixing the crosslinking agent and platinum catalyst into the liquid silica gel, it is injected into the model, and after a period of vulcanization reaction, it can be cured and formed (the reaction can be done at room temperature, so it is called room temperature vulcanized silicone rubber, and it can also be heated slightly increase reaction speed). and form the final product. Adding different additives can make the silicone material have different specific gravity, hardness, strength, color and texture. Silicone rubber has better high and low temperature resistance than ordinary pure organic rubber. Traditional rubber will be frozen and brittle in space where the sun cannot reach, and it will be sealed and sealed during the period. The biggest feature of silicone rubber developed as a space material is that it is not afraid of high temperature and can withstand severe cold. Whether in extreme environments of 300°C or -90°C, it retains its chemical structure and its original flexibility. Compared with natural rubber, there is no bacterial growth. And its surface tension is very low, it is not easy to be soaked and deformed by sweat and rain, and it has strong waterproof and corrosion performance. Therefore, the service life of silicone rubber products in the natural environment can reach several decades. Silicone rubber is not all-powerful either, and its tear resistance is one of the lowest among rubbers. Therefore, small cracks are easily generated in the connection part of the silicone strap and the metal buckle due to a large external force. Therefore, when using a silicone strap, you need to pay attention to the connection between the strap and the metal buckle, and do not pull it vigorously. In addition, the silicone strap should be wiped with a soft cloth from time to time to remove some hard dust particles to prevent it from scratching the surface of the silicone and causing small cracks, which can also effectively prolong the life of the strap. Silica gel (Silica gel; Silica) alias: Silicone rubber is a highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel is divided into: macroporous silica gel, coarse-pored silica gel, B-type silica gel, and fine-pored silica gel according to the size of its pore size.
We also sell Silicone Case, which is generally made of rubber, soft and elastic, and is often used to protect electronic digital products from accidental drops or wear. If you need a Silicone Wristband, you can also consult us. Silicone wristbands are more associated with various organizational activities, brand promotion, sports, etc. A good design can convey a profound meaning.
