Three main reasons for aging of silicone tube
Silicone tube in the use of a period of time will appear to be hard, no problem of elasticity, more serious still hair. This is
What are the causes of the aging of silicone tube? Small series on the simple introduction of the old
Three major reasons for the:
1 role of ozone
The chemical activity of ozone is high, and the damage is greater, it is also the same as the molecular chain, but the effect of ozone on the silicone tube.
The condition is different from the deformation of the silicone tube. As for the silicone tube deformation is mainly unsaturated rubber), and stress
Crack direction, the so-called "ozone cracking"; effect on the deformation of the silicone tube, only the surface oxide film and the tortoise
Crack.
2 moisture content
The silicone tube is easy to damage in the humid air or rain soaked in water, and this is because of the silicone tube in water soluble substances and water
Tsuen group of components are water extraction solution. Cause of hydrolysis or absorption. Especially in the alternate soaking water and atmospheric exposure for
With the next, will accelerate the destruction of silicone tube. But in some cases the moisture content of the silicone tube can not play a role, and even have a delay.
The role of.
3 oxidation
Oxygen free radical chain reaction in rubber with rubber molecules, the molecular chain rupture or excessive crosslinking, caused by rubber performance
Change. Oxidation is one of the important reasons for aging of rubber.
