1. Organic silica
Introduction:
Organic silica gel belongs to the special rubber in synthetic rubber, which is divided into solid and liquid according to the form. The liquid is divided into room temperature vulcanization type and high temperature vulcanization type according to the vulcanization temperature. The basic structural unit of silicone products is composed of silicon-oxygen chains, and the side chains are connected to various other organic groups through silicon atoms. Therefore, the structure of silicone products contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it combine the characteristics of organic substances with the functions of inorganic substances.
Product Features:
Temperature resistance properties, weather resistance, electrical insulating properties, physiological inertness, low surface tension and low surface energy.
Silicone uses:
Silicone has these excellent properties, so its application range is very wide. It is not only used as a special material in aviation, cutting-edge technology and military technology sectors, but also in various sectors of the national economy. Metal and paint, medicine and medical treatment, etc.

2. Inorganic silica gel
Introduction:
The chemical formula of inorganic silica gel is xSio2 yH2O. Transparent or milky white granular solid, it is a highly active adsorption material, usually an amorphous machine-made product obtained by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. It is made of minerals existing in nature after washing and processing into granules or beads. The main component of inorganic silica gel is silica, which is an amorphous machine made of sodium silicate and sulfuric acid in silica. finished product. Inorganic silica gel is washed and processed into granular or bead shape from minerals existing in nature.
Product Features:
The structure of inorganic silica gel is very similar to a sponge, which is composed of interconnected pores to form a capillary adsorption system with a huge surface area, which can absorb and retain water vapor. Under the condition of 100% humidity, it can absorb and condense water vapor equivalent to 40% of its own weight. High adsorption performance, can adsorb a variety of substances. Add dilute sulfuric acid (or hydrochloric acid) to the aqueous solution of water glass and let it stand, it becomes a hydrous silicic acid gel and solidifies, with good thermal stability (the entry "thermal stability" is provided by the industry encyclopedia), and chemically stable , have high mechanical strength and so on.
use:
Inorganic silica gel has a wide range of choices for packaging materials, generally OPP/PE, PET/PE film, non-woven fabric, composite paper, etc. It is used for gas drying, gas absorption, liquid dehydration, chromatography analysis, etc. It is also used as a catalyst. If cobalt chloride is added, it turns blue when dry and red when it absorbs water.
