To prevent the aging of insulating paperboard, the following points are required:
1. prevent the high-density insulating paperboard from being in a high temperature environment, because the service life of the high-density insulating paperboard will be halved for every 8 ° C increase in the ambient temperature
2. avoid contacting corrosive chemical gases or liquids, because these will denature the insulation performance of high-density insulating paperboard and reduce the insulation strength
3. avoid light and radiation, because light and radiation will change the molecular structure of insulation and reduce the insulation strength
4. clean transportation tools with protective measures shall be used during transportation, and shall not be transported together with contaminated materials; During handling and stacking, it is not allowed to drop the cardboard from a high place.
5. the high-density insulating paperboard shall be properly kept to prevent the impact of rain, snow, ground moisture, acid, alkali and chemical gases, and the use environment shall be kept clean.
