What is silicone material:


Silica gel is a highly active adsorbent material, which is an amorphous substance with a chemical formula of mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gels have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel is classified according to its pore size: macroporous silica gel, coarse pore silica gel, B-type silica gel, and fine pore silica gel. Due to the different pore structure, their adsorption properties are different. The coarse pore silica gel has a higher adsorption amount in the case of high relative humidity, and the fine pore silica gel has a higher adsorption amount than the coarse pore silica gel in the case of a relatively low relative humidity, and the B type silica gel has a pore structure in the coarse and fine pores. Between silica gel, the amount of adsorption is also between coarse and fine pores. Macroporous silica gel is generally used as a catalyst carrier, a matting agent, a toothpaste abrasive, and the like. Therefore, different varieties should be selected according to different uses. After the silica gel adsorbs moisture, it can be regenerated by exposure, baking, air drying, and the like.

   [Safety Performance] The main component of silica gel is silica, which is chemically stable and non-toxic. Silica gel has a strong adsorption capacity and can cause dryness on human skin. If the silicone enters the eye, rinse with plenty of water and seek medical attention as soon as possible. Blue silica gel is toxic due to the small amount of cobalt chloride. Avoid contact with food and inhalation. If a poisoning event occurs, seek medical attention immediately. [Main use] The strong adsorption of silica gel can quickly and effectively absorb the moisture in the sealed package, and it is chemically stable, non-toxic and harmless. In addition to the continuous innovation and development in recent years, various silica gels have been widely used for drug purification. DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification, beer purification, advanced coatings, and resin production or storage.


     In our daily life and production and management activities, silica gel is often used in the following aspects: precision optical instruments, dry and mildewproof packaging of electronic appliances; leather drying, such as leather, leather bags, leather shoes, dry and quality Function; food drying, more common in biscuits and fried foods to ensure that the food is crisp; in the drying of medicines, put in the medicine bottle to ensure the extended shelf life of the drug; container drying: transport containers at different latitudes It will form the “inner rain” in the box. If you use silica gel desiccant, it can absorb the water equivalent to its own weight. During the 50-day long-distance transportation, it can effectively reduce the dew point and make the container condensate. The phenomenon is controlled. Hotel items, such as placed in the closet, in the shoes and under the bed, absorb a variety of odors, keep the air dry and fresh.
