The importance of vacuum insulation test

Nowadays, the world energy crisis is becoming more and more serious, energy cost is rising, energy saving and emission reduction has become a common problem facing the world. Vacuum Insulation Board (VIP) is an advanced and efficient energy-saving products, is based on the principle of vacuum insulation, by maximizing the plate in the vacuum and filling the core layer insulation material to achieve insulation heat conduction, so as to achieve the purpose of heat preservation, energy-saving. But the performance of VIP testing is a difficult problem, its performance depends on the level of the vacuum in the board. Because VIP can not open holes, vacuum cavity narrow, ordinary methods of detection technology can not be used, so it must be through some special methods to identify the performance of VIP to ensure that the production of VIP products to meet quality requirements.
