气相防锈塑料薄膜是气相防锈技术的一种应用形式,它是一种特殊的功能性薄膜,其核心技术是气相缓蚀剂技术。气相缓蚀剂又叫气相防锈剂(VaporPhaseCorrosionInhibitor,简称VPI)、气化性防锈剂(VolatileCorrosionInhibitor,简称VCI),它是一类特殊的化学物质,在常温下具有升华性或挥发性,并且具有适宜的蒸气压。它挥发出来的蒸气到达金属表面后与金属发生钝化作用,从而减轻或抑制金属锈蚀,使金属得到保护。
Vapor-phase anti-rust plastic film is a kind of application of vapor-phase anti-rust technology, it is a special functional film, its core technology is vapor phase inhibitor technology. Vapor phase inhibitor is also called VaporPhaseCorrosionInhibitor (VPI) and VolatileCorrosionInhibitor (VCI). It is a kind of special chemical substance that has sublimation or volatility at normal temperature, and With suitable vapor pressure. Volatile vapor from it reaches the metal surface and passivates the metal, thereby reducing or inhibiting the corrosion of the metal, so that the metal is protected.
