What is organic silica gel?

What is organic silica gel?

   Organic silica is a compound that contains si-c bonds, and at least one organic base is directly connected to the silicon atom, and it is customary to use compounds such as oxygen, sulfur, and nitrogen that connect organic to silicon atoms as silicone compounds. Among them, polysiloxane with silicon oxygen bond (-si-o-si-) as the skeleton, is the most of silicone compounds, the most research, the most widely used category, about 90% of the total dosage.


Silicone materials have a unique structure:

(1) sufficient methyl atoms on the SI atom will shield the high energy polysiloxane main chain;

(2) C-h of the polarity, so that the interaction between molecules is very weak;

(3) The Si-o key length is longer, the Si-o-si key angle is big;

(4) The Si-o bond is a covalent bond with a characteristic of 50% ionic bonds (the covalent bond has directionality and the ionic bonds have no directionality).


Morphological classification:

   Can be divided into: (Silicone chemical reagents), silicone oil (silicone grease, silicone emulsion, silicone surfactant), high-temperature vulcanized silicone rubber, liquid silicone rubber, silicone resin, complex and so on.

  

(heat vulcanization) silicone rubber and RTV (including Low-temperature vulcanization) silicone rubber two broad categories.

   

   Due to the performance of organic materials, the surface tension is low, the viscosity temperature coefficient is small, high compressibility, gas permeability of the basic properties, and has high and low temperature, electrical insulation, oxidation stability, weather resistance, refractory, hydrophobic, corrosion resistance, non-toxic tasteless and physiological inertia and other outstanding characteristics, widely used in aerospace, electrical and electronic, construction, Transport, chemical, textile, food, light industry, medical and other industries, of which silicone is mainly used for sealing, adhesion, lubrication, coating, surface activity, demoulding, defoaming, inhibition of foam, waterproof, moisture-proof, inert filling. With the continuous growth of the number and variety of organic silicon, the application field has been widened to form an important product system unique to the new chemical material industry, and many varieties are irreplaceable and essential for other chemicals.
