粮仓结露,对安全储粮威胁很大.积极探讨粮仓结露成因及其相关因素,对有效预防和处理粮仓结露,是非常必要的.(一)大量凝结核存在,加快粮仓结露形成实验证明:在纯净空气里,要使水汽凝结是很困难的,即使水汽饱和到相对湿度为300～400%,也不会发生凝结,只有当相对湿度达700～800%时,水汽发生凝结才有可能.在实际大气中,根本达不到这样的饱和程度.而云、雾等水汽凝结现象却时常发生,甚至有时水汽饱和程度达不到100%,凝结也会产生.其原因还是由于大气中存在
Condensation of grain silos, the threat to the safety of grain storage is very large.Study on the causes of formation of granary dew and its related factors, it is very necessary to effectively prevent and deal with the dew condensation of granaries.A large number of condensation nuclei exist to speed up the formation of granary dew Experiments show that in pure air, it is very difficult to condense the water vapor. Even if the water vapor is saturated to a relative humidity of 300 to 400%, no condensation will occur. Only when the relative humidity reaches 700 to 800%, the water vapor condenses It is possible that in the real atmosphere, it is impossible to achieve such a degree of saturation, while condensation phenomena such as clouds and fog occur frequently, even when the degree of saturation of water vapor is less than 100% and the condensation will occur.
