Silica gel alias：Silicic acid gel is a kind of high activity sorbing material, belongs to amorphous substance.Silica gel main component is two
Silica, chemical property are stablized, do not burn.
Most outstanding properties are：
1. temperature-resistance characteristic
Organosilicon product is using silicon-oxygen (Si-O) key as backbone structure, and the bond energy of C-C keys is 82.6 kilocalories/gram point
The bond energy of son, Si-O keys is 121 kilocalories/gram molecule in organosilicon, so the thermal stability of organosilicon product is high, under high temperature
The chemical bond of (or radiation exposure) molecule is not broken, does not decompose.Organosilicon not only can high temperature resistant, and it is low temperature resistant, can be one
It is used within the scope of a very wide temperature.Either chemical property or physical mechanical property, variation with temperature all very littles.
2. weatherability
The main chain of organosilicon product is-Si-O-, and no double bond exists, therefore is not easy to be decomposed by ultraviolet light and ozone.
Organosilicon has thermal stability more better than other high molecular materials and radiation resistance and weather-proof ability.Natural environment in organosilicon
Under service life up to decades.
3. electrical insulation properties
Organosilicon product all has good electrical insulation capability, dielectric loss, proof voltage, resistance to electric arc, Inverter fed motor, volume
Resistance coefficient and surface resistivity etc. come out at the top in insulating materials, and their electric property is by temperature and frequency
Influence very little.Therefore, they are a kind of electrically insulating materials of stabilization, are widely used in electronics, in electrical industry.Organosilicon
Other than with excellent heat resistance, also there is excellent water repellency, this is that electrical equipment is high using having under hygrometric state condition
The guarantee of reliability.
4. biological property
Silicon rubber has good biocompatibility, nonirritant to tissue, non-toxic, without allergic reaction, body
Rejection is few；With good physicochemical property, with can be kept in body fluid and tissue contact process its original elasticity and
Pliability is not degraded.
5. low surface tension and low-surface-energy
The main chain of organosilicon is very submissive, and intermolecular force ratio hydrocarbon wants much weaker, therefore, than same point
The hydrocarbon viscosity of son amount is low, and surface tension is weak, and surface energy is small, and film forming ability is strong.This low surface tension and low surface
Can be the main reason for it obtains many-sided application：The items superiority such as hydrophobic, defoaming, foam is stable, anti-sticking, lubrication, glazing
Energy.
