What are the factors that affect the aging of the mold?
Die silicone is a synthetic rubber with good comprehensive properties, which has good electrical insulation properties, aging resistance, chemical stability and radiation resistance, and can be used in -60 degree to 250 degree. Usually has a good silicone mold heat oxygen aging resistance, ozone resistance, light aging resistance and aging resistance of hou. However, now more and more of the mold silicone anti aging weakened, the use of the cycle is also greatly reduced, the impact of the aging of silicone aging factors have the following several aspects:
First, the impact of ozone to strengthen. With the increase of ozone in the atmosphere, the chemical activity of ozone is strengthened, and the destructive increase, which makes the molecular chain rupture. To increase the effect of ozone on silica gel, and ozone mainly acts on the silicon rubber deformation generated ozone cracking phenomenon. Second, oxidation is also an aspect of the aging of the mold silicone. The role of oxygen in the aging of silicone molecules in the rubber, the molecular chain rupture, and the change of the properties of silica gel. In addition, silicone mold in the wet, rain or soaked in water are easily damaged. Especially in the case of water immersion and atmospheric exposure, will accelerate the aging of the mold silicone.
Aging is not just a mold of the mold, it is true, of course, if we make the appropriate measures for these factors or to avoid these problems, that is, the:
1 avoid to make the mold silicone or silicone products too much contact with the strong oxide; do not open exposure.
2 silica gel storage do not have wet, rain phenomenon.
To sum up, we only in accordance with the reasonable method to use the mold silicone, can slow down the aging of the mold silicone, hope that we can make full use of every resource, so that it has value!
