PU duct hose pipe is very important for the production and processing of many enterprises. It is precisely because of the increasing demand for duct hose in various fields that many enterprises will buy a large number of different types of duct hose at one time to facilitate the use of hoses in the later stage of the enterprise! But we must know that the requirements of hoses in storage environment and other aspects are very high. If you just find a place to store these hoses, then it may accelerate the aging of the hose. So that it will seriously reduce the service life of the hose! So how to prevent PU duct hose pipe from excessive aging? Follow with Orientflex to find out!
- External environmental: Mainly oxygen, oxide, ozone, heat, light, radiation, mechanical fatigue, lack of processing process, etc.The effect of ozone is strengthened.With the increase of ozone in the atmosphere, the chemical activity of ozone increases and the destruction increases, which causes the molecular chain to break. The influence of ozone on the PU duct hose pipe is increased, and ozone mainly acts on the deformed silicone rubber to produce the phenomenon of ozone cracking. Oxidation is also an aspect of silica gel aging. The aging effect of oxygen and silica gel molecules in rubber occurs, and the molecular chain breaks, resulting in the change of silica gel properties.
- Silicone is easy to be damagedin the wet, rain or soaked in water. The aging of PU duct hose pipe will be accelerated especially in the case of water immersion and atmospheric exposure.
- Internal structural: Mainly including the type of rubber, molding method, degree of bonding, the type of drugs, factors in the processing.
